  • Inequalities in access to minimally invasive general surgery: a
           comprehensive nationwide analysis across 20 years

    • Free pre-print version: Loading...

      Abstract: Background Minimally invasive surgery (MIS) has profoundly changed standards of care and lowered perioperative morbidity, but its temporal implementation and factors favoring MIS access remain elusive. We aimed to comprehensibly investigate MIS adoption across different surgical procedures over 20 years, identify predictors for MIS amenability and compare propensity score-matched outcomes among MIS and open surgery. Methods Nationwide retrospective analysis of all hospitalizations in Switzerland between 1998 and 2017. Appendectomies (n = 186,929), cholecystectomies (n = 57,788), oncological right (n = 9138) and left hemicolectomies (n = 21,580), rectal resections (n = 13,989) and gastrectomies for carcinoma (n = 6606) were included. Endpoints were assessment of temporal MIS implementation, identification of predictors for MIS access and comparison of propensity score-matched outcomes among MIS and open surgery. Results The rates of MIS increased for all procedures during the study period (p ≤ 0.001). While half of all appendectomies were performed laparoscopically by 2005, minimally invasive oncological colorectal resections reached 50% only by 2016. Multivariate analyses identified older age (p ≤ 0.02, except gastrectomy), higher comorbidities (p ≤ 0.001, except rectal resections), lack of private insurance (p ≤ 0.01) as well as rural residence (p ≤ 0.01) with impaired access to MIS. Rural residence correlated with low income regions (p ≤ 0.001), which themselves were associated with decreased MIS access. Geographical mapping confirmed strong disparities for rural and low-income areas in MIS access. Matched outcome analyses revealed benefits of MIS for length of stay, decreased surgical site infection rates for MIS appendectomies and cholecystectomies and higher mortality for open cholecystectomies. No consistent morbidity or mortality benefit for MIS compared to open colorectal resections was observed. Conclusion Unequal access to MIS exists in disfavor of older and more comorbid patients and those lacking private insurance, living in rural areas, and having lower income. Efforts should be made to ensure equal MIS access regardless of socioeconomic or geographical factors.

  • Laparoscopic versus open right posterior sectionectomy: an international,
           multicenter, propensity score-matched evaluation

    • Free pre-print version: Loading...

      Abstract: Background Although laparoscopic liver resection has become the standard for minor resections, evidence is lacking for more complex resections such as the right posterior sectionectomy (RPS). We aimed to compare surgical outcomes between laparoscopic (LRPS) and open right posterior sectionectomy (ORPS). Methods An international multicenter retrospective study comparing patients undergoing LRPS or ORPS (January 2007—December 2018) was performed. Patients were matched based on propensity scores in a 1:1 ratio. Primary endpoint was major complication rate defined as Accordion ≥ 3 grade. Secondary endpoints included blood loss, length of hospital stay (LOS) and resection status. A sensitivity analysis was done excluding the first 10 LRPS patients of each center to correct for the learning curve. Additionally, possible risk factors were explored for operative time, blood loss and LOS. Results Overall, 399 patients were included from 9 centers from 6 European countries of which 150 LRPS could be matched to 150 ORPS. LRPS was associated with a shorter operative time [235 (195–285) vs. 247 min (195–315) p = 0.004], less blood loss [260 (188–400) vs. 400 mL (280–550) p = 0.009] and a shorter LOS [5 (4–7) vs. 8 days (6–10), p = 0.002]. Major complication rate [n = 8 (5.3%) vs. n = 9 (6.0%) p = 1.00] and R0 resection rate [144 (96.0%) vs. 141 (94.0%), p = 0.607] did not differ between LRPS and ORPS, respectively. The sensitivity analysis showed similar findings in the previous mentioned outcomes. In multivariable regression analysis blood loss was significantly associated with the open approach, higher ASA classification and malignancy as diagnosis. For LOS this was the open approach and a malignancy. Conclusion This international multicenter propensity score-matched study showed an advantage in favor of LRPS in selected patients as compared to ORPS in terms of operative time, blood loss and LOS without differences in major complications and R0 resection rate.

  • Novel noninvasive liver fibrotic markers to predict postoperative
           re-bleeding after laparoscopic splenectomy and azygoportal disconnection:
           a 1-year prospective study

    • Free pre-print version: Loading...

      Abstract: Background Esophagogastric variceal re-bleeding (EGVR) is a common and potentially lethal complication after open or laparoscopic splenectomy and azygoportal disconnection (LSD) in patients with cirrhosis and portal hypertension. Currently, noninvasive biomarkers for predicting EGVR are lacking. This prospective study focused on developing a noninvasive and convenient clinical model for predicting postoperative EGVR. Methods Between September 2014 and March 2017, we enrolled 164 patients with cirrhosis who successfully underwent LSD. Based on the absence or presence of EGVR, patients were divided into EGVR and non-EGVR groups. We used correlation analysis to determine significant candidate variables among the liver fibrotic markers procollagen type III (PC-III), hyaluronidase (HA), laminin (LN), and type IV collagen (C-IV). Results Postoperative EGVR occurred in 22 (13.41%) patients. Correlation analyses showed that LN (r = 0.375; p < 0.001) and C-IV (r = 0.349; p < 0.001) were significantly positively associated with EGVR. The area under the receiver operating characteristic curve (AUC) of LN was 0.817 (95% confidence interval [CI] 0.722–0.913); that of C-IV was 0.795 (95% CI 0.710–0.881). In logistic multivariate regression, cutoff values LN ≥ 64 µg/L and of C-IV ≥ 65 µg/L were independent risk factors for EGVR. LN ≥ 64 µg/L combined with C-IV ≥ 65 µg/L was the best performing model, with AUC 0.867 (95% CI 0.768–0.967). Conclusion LN and C-IV are potential markers to predict EGVR. Combining the two markers showed satisfactory ability to predict EGVR in patients with cirrhosis and portal hypertension after LSD.

  • Impact of smoking on weight loss outcomes after bariatric surgery: a
           literature review

    • Free pre-print version: Loading...

      Abstract: Background The association between smoking and surgical complications after bariatric surgery has been well-established. However, given that this patient population is inherently weight-concerned, understanding the effects of tobacco use on postoperative weight loss is essential to guiding clinicians in counseling patients. We aimed to summarize the current literature examining the effects of preoperative and postoperative smoking, as well as changes in smoking status, on bariatric surgery weight loss outcomes. Methods Ovid MEDLINE, PubMed, and SCOPUS databases were queried to identify relevant published studies. Results Overall, 20 studies were included. Preoperative and postoperative smoking rates varied widely across studies, as did requirements for smoking cessation prior to bariatric surgery. Reported preoperative smoking prevalence ranged from 1 to 62%, and postoperative smoking prevalence ranged from 6 to 43%. The majority of studies which examined preoperative and/or postoperative smoking habits found no association between smoking habits and postoperative weight loss outcomes. A minority of studies found relatively small differences in postoperative weight loss between smokers and nonsmokers; these often became nonsignificant with longer follow-up. No studies found significant associations between changes in smoking status and weight loss outcomes. Conclusion While smoking has been associated with weight loss in the general population, most current evidence demonstrates that smoking habits are not associated with weight loss outcomes after bariatric surgery. However, due to the heterogeneity in study design and analysis, no definitive conclusions can be made, and more robust studies are needed to investigate any relationship between smoking and long-term weight loss outcomes. Given the established increased risk of surgical complications and mortality in smokers, smoking cessation should be encouraged.

  • Telemedicine for postoperative follow-up, virtual surgical clinics during
           COVID-19 pandemic

    • Free pre-print version: Loading...

      Abstract: Summary and background data Recent coronavirus outbreak and “stay at home” policies have accelerated the implementation of virtual healthcare. Many surgery departments are implementing telemedicine to enhance remote perioperative care. However, concern still arises regarding the safety of this modality in postoperative follow-up after gastrointestinal surgery. The aim of the present prospective study is to compare the use of telemedicine clinics to in-person follow-up for postoperative care after gastrointestinal surgery during COVID-19 outbreak. Methods Prospective study that included all abdominal surgery patients operated since the COVID-19 outbreak. On discharge, patients were given the option to perform their postoperative follow-up appointment by telemedicine or by in-person clinics. Demographic, perioperative, and follow-up variables were analyzed. Results Among 219 patients who underwent abdominal surgery, 106 (48%) had their postoperative follow-up using telemedicine. There were no differences in age, gender, ASA score, and COVID-19 positive rate between groups. Patients who preferred telemedicine over in-person follow-up were more likely to have undergone laparoscopic surgery (71% vs. 51%, P = 0.037) and emergency surgery (55% vs. 41%; P = 0.038). Morbidity rate for telemedicine and in-person group was 5.7% and 8%, (P = 0.50). Only 2.8% of patients needed an in-person visit following the telemedicine consult, and 1.9% visited the emergency department. Conclusions In the current pandemic, telemedicine follow-up can be safely and effectively performed in selected surgical patients. Patients who underwent laparoscopic and emergency procedures opted more for telemedicine than in-person follow-up.

  • Optimal drainage of anastomosis stricture after living donor liver
           transplantation

    • Free pre-print version: Loading...

      Abstract: Background Endoscopic biliary stenting (EBS) with a fully covered, self-expandable metallic stent (FC-SEMS) and plastic stent (PS) is safe and efficient for biliary anastomotic strictures (ASs) after a deceased donor liver transplantation. Limited studies have investigated the use of FC-SEMSs for biliary strictures post-living donor liver transplantation (LDLT). We compared the resolution rate of biliary ASs post-LDLT and the 12-month recurrence rates post-stent removal between EBS with an FC-SEMS, PS, and percutaneous transhepatic biliary drainage (PTBD). Methods Patients with biliary ASs after an LDLT (mean age: 57.3 years, 76.1% men) hospitalized between 2014 and 2017 were enrolled. Endoscopic retrograde cholangiopancreatography (ERCP) was repeated every 3–4 months. Patients were followed-up for at least 1-year post-stent removal. Results Of the 75 patients enrolled, 16, 20, and 39 underwent EBS with an FC-SEMS, PS, and PTBD, respectively. Median follow-up period was 39.2 months. Fewer ERCP procedures were needed in the FC-SEMS group than in the PS group (median, 2 vs. 3; P = 0.20). Median stent indwelling periods were 4.7, 9.3, and 5.4 months in the FC-SEMS, PS, and PTBD groups, respectively (P = 0.006). The functional resolution rate was lower in the PS group (16/20) than in the FC-SEMS (16/16) or PTBD (39/39) group (P = 0.005). The radiologic resolution rate was higher in the FC-SEMS group (16/16) than in the PS group (14/20) (P = 0.07). The 12-month recurrence rates showed no significant differences (FC-SEMS, 4/16; PS, 3/16; PTBD, 6/39; P = 0.66). The rates of complications during treatment differed significantly between the groups (P = 0.04). Stent migration occurred in 1 (6.3%) and 5 (25.0%) patients in the FC-SEMS and PS groups, respectively (P = 0.59). Conclusions EBS with an FC-SEMS is comparable with EBS with a PS or PTBD in terms of biliary stricture resolution and 12-month recurrence rates. The use of FC-SEMSs is potentially effective and safe for biliary AS resolution after LDLT.

  • Three years prospective clinical and radiologic follow-up of laparoscopic
           sacrocolpoperineopexy

    • Free pre-print version: Loading...

      Abstract: Background When Rectocele is part of a complex pelvic organ prolapse, a full repair is recommended. The aim of this study was to evaluate the clinical and radiological results after laparoscopic surgery in patients with symptomatic rectocele and III/IV stage vaginal vault prolapse Methods This is a prospective cohort study of women with symptomatic rectoceles and middle compartment prolapse operated on between 2013 and 2015, who underwent a laparoscopic sacrocolpoperineopexy with synthetic Y mesh attached to puborectalis muscles, the anterior and posterior vagina wall and the sacrum. The clinical outcomes measured were symptoms of prolapse, obstructive defecation syndrome and quality of life. Radiological outcomes were distance of the vaginal vault below pubococcigeal line and depth of rectovaginal wall protrusion in dynamic pelvic resonance. Results 33 patients were included. 32 of them remained asymptomatic after a three years follow-up. Significant differences were shown in the obstructed defecation score and quality of life after 6, 12 and 36 months compared to preoperatively. No differences were identified when the postoperative results were compared. Significant differences were shown in preoperative vaginal vault prolapse (3.2 cms ± 0.8 SD below the pubococcigeal Line) and rectocele size, compared with 1 and 3 years after surgery. There were no significant differences in vaginal vault prolapse when compared after 1 and 3 years. When rectocele size after 1 and 3 years was compared, significant differences were shown, but only one clinical recurrence (3%) was identified after a mean follow-up of 47 months. Conclusions Laparoscopic sacrocolpoperineopexy in patients with symptomatic rectocele and III/IV vaginal vault prolapse solves the constipation and obstructed defecation with an excellent quality of life and low clinical recurrences. Radiological deterioration, especially in rectocele size, was identified in the mid-term follow-up without clinical significance.

  • A nomogram illustrating the probability of anastomotic leakage following
           cervical esophagogastrostomy

    • Free pre-print version: Loading...

      Abstract: Background Early diagnosis of anastomotic dehiscence following cervical esophagogastrostomy may become difficult. Estimation of an individual probability could help to establish preventive and diagnostic measures. The predictive impact of epidemiological, surgery-related data and laboratory parameters on the development of anastomotic dehiscence was investigated in the immediate perioperative period. Methods Retrospective study in 412 patients with cervical esophagogastrostomy following esophagectomy. Epidemiological data, risk factors, underlying disease, pre-treatment- and surgery-related data, C-reactive protein and albumin levels pre-and post-operatively were evaluated. We applied univariable and multivariable logistic regression analysis and developed a nomogram for individual risk assessment. Results There were 345 male, 67 female patients, mean aged 61.5 years; 284 had orthotopic, 128 retrosternal gastric pull-up; 331 patients had carcinoma, 81 non-malignant disease. Mean duration of operation was 184 min; 235 patients had manual, 113 mechanical and 64 semi-mechanical suturing; 76 patients (18.5%) developed anastomotic dehiscence clinically evident at mean 11.4 days after surgery. In univariable testing young age, retrosternal conduit transposition, manual suturing, high body mass index, high ASA and high postoperative levels of C-reactive protein were predictors for anastomotic leakage. These six parameters which had yielded a p < 0.1 in the univariable analysis, were entered into a multivariable analysis and a nomogram allowing the determination of the patient’s individual risk was created. Conclusion By using the nomogram as a supportive measure in the perioperative management, the patient’s individual probability of developing an anastomotic leak could be quantified which may help to take preventive measures improving the outcome.

  • Guidelines for the performance of minimally invasive splenectomy

    • Free pre-print version: Loading...

      Abstract: Background Minimally invasive splenectomy (MIS) is increasingly favored for the treatment of benign and malignant diseases of the spleen over open access approaches. While many studies cite the superiority of MIS in terms of decreased morbidity and length of stay over a traditional open approach, the comparative effectiveness of specific technical and peri-operative approaches to MIS is unclear. Objective To develop evidence-based guidelines that support clinicians, patients, and others in decisions on the peri-operative performance of MIS. Methods A guidelines committee panel of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) including methodologists used the Grading of Recommendations Assessment, Development and Evaluation approach to grade the certainty of evidence and formulate recommendations. Results Informed by a systematic review of the evidence, the panel agreed on eight recommendations for the peri-operative performance of MIS for adults and children in elective situations addressing six key questions. Conclusions Conditional recommendations were made in favor of lateral positioning for non-hematologic disease, intra-operative platelet administration for patients with idiopathic thrombocytopenic purpura instead of preoperative administration, and the use of mechanical devices to control the splenic hilum. Further, a conditional recommendation was made against routine intra-operative drain placement.

  • Lumen-apposing metal stents for approved and off-label indications: a
           single-centre experience

    • Free pre-print version: Loading...

      Abstract: Background and study aims Lumen-apposing stents (LAMS) are approved to treat peripancreatic collections and for gallbladder and bile duct drainage. Over the last years, LAMS have also been used for off-label indications including gastrojejunostomy, gastro-gastrostomy and drainage of postsurgical collections. We aimed to analyze indications, technical/clinical success rates and complications of all LAMS placed over the last 2 years. Patients and methods Data from 61 consecutive LAMS (Hot Axios, Boston Scientific) in 57 patients were analyzed. Technical success was defined as successful deployment of the LAMS in the desired position. Clinical success was defined as follows: for pancreatic collections: resolution without the need for non-endoscopic interventions; for choledochoduodenostomy: ≥ 50% drop in baseline serum bilirubin within 2 weeks AND patient can receive chemotherapy if indicated; for gastrojejunostomy: resolution of gastric outlet obstruction and successful re-initiation of oral intake; for gastro-gastrostomy: successful endoscopic access to the excluded stomach; for gallbladder or postsurgical collection drainage: resolution of sepsis. Results Indications were drainage of peripancreatic collections in 24 cases (39.3%), choledochoduodenostomy in 13 (21.3%), gastrojejunostomy in 6 (9.8%), gastro-gastrostomy in 13 (21.3%), gallbladder drainage in 1 (1.6%) and postsurgical collection drainage in 4 (6.6%). Overall technical and clinical success rates were high (57/61; 93.4% and 54/61; 88.5%, respectively). Clinical success rate for non-approved indications was 95.6% (22/23 cases). Complications occurred in 13 patients (21.3%, 4 serious). Conclusions LAMS are increasingly used in interventional endoscopy. In our cohort, more than one third of LAMS are placed for off-label indications, with a high success rate and acceptable complication rate.

  • Transoral robotic thyroidectomy versus transoral endoscopic thyroidectomy:
           a propensity-score-matched analysis of surgical outcomes

    • Free pre-print version: Loading...

      Abstract: Background Transoral endoscopic thyroidectomy vestibular approach (TOETVA) has been shown to be safe and has similar outcomes as open thyroidectomy for selected patients. It is not clear if transoral robotic thyroidectomy (TORT) may extend transoral endoscopic thyroidectomy to more complex thyroid operations. The study aimed to compare the safety and outcomes of TORT with those of TOETVA. Methods We retrospectively reviewed all patients who had TORT and TOETVA performed by a single surgeon from June 2017 to May 2019. Intrathoracic goiter and combined operations were excluded. Surgical outcomes were compared after propensity score matching. Learning curves, as measured by operating time, were evaluated. Results A total of 150 patients underwent 154 transoral (55 TORT and 99 TOETVA) thyroidectomy. Of the 154 operations, 28 (18.2%) were bilateral total thyroidectomy and 126 (81.8%) were unilateral thyroid lobectomy. After propensity score matching, we found a longer operative time (median [interquartile range]) for TORT (n = 53) than for the TOETVA (308 [284–388] vs 228 [201–267] min, P < 0.001). Blood loss and visual analog scale scores for pain were not significantly different between the two groups. Central neck lymph node dissection was performed more frequent in the TORT group (28 of 53 [52.8%] vs 10 of 53 [18.9%], P = 0.001), and when performed, the numbers of total and positive lymph nodes did not differ significantly between the two groups. The rates of hypoparathyroidism and recurrent laryngeal nerve injury did not differ significantly between the two groups. There was no conversion to open thyroidectomy, mental nerve injury, or surgical site infection. The learning curve for TORT was 25 cases, but no obvious learning curve was observed for TOETVA. Conclusions TORT requires a longer operative time, but is as safe as TOETVA and may be useful for more complex thyroid operations.

  • Technology development of hyperthermic pressurized intraperitoneal aerosol
           chemotherapy (hPIPAC)

    • Free pre-print version: Loading...

      Abstract: Background Optimized drug delivery systems are needed for intraperitoneal chemotherapy. The aim of this study was to develop a technology for applying pressurized intraperitoneal aerosol chemotherapy (PIPAC) under hyperthermic conditions (hPIPAC). Methods This is an ex-vivo study in an inverted bovine urinary bladder (IBUB). Hyperthermia was established using a modified industry-standard device (Humigard). Two entry and one exit ports were placed. Warm-humid CO2 was insufflated in the IBUB placed in a normothermic bath to simulate body thermal inertia. The temperature of the aerosol, tissue, and water bath was measured in real-time. Results Therapeutic hyperthermia (target tissue temperature 41–43 °C) could be established and maintained over 30 min. In the first phase (insufflation phase), tissue hyperthermia was created by insufflating continuously warm-humid CO2. In the second phase (aerosolization phase), chemotherapeutic drugs were heated up and aerosolized into the IBUB. In a third phase (application phase), hyperthermia was maintained within the therapeutic range using an endoscopic infrared heating device. In a fourth phase, the toxic aerosol was discarded using a closed aerosol waste system (CAWS). Discussion We introduce a simple and effective technology for hPIPAC. hPIPAC is feasible in an ex-vivo model by using a combination of industry-standard medical devices after modification. Potential pharmacological and biological advantages of hPIPAC over PIPAC should now be evaluated.

  • Quality of life and patient satisfaction after single- and multiport
           laparoscopic surgery in colon cancer: a multicentre randomised controlled
           trial (SIMPLE Trial)

    • Free pre-print version: Loading...

      Abstract: Background The clinical benefits of single-port laparoscopic surgery (SPLS) in patients with colon cancer patients are unclear because only a few studies have reported on the quality of life (QoL) of such patients. This study aimed to compare the QoL and patient satisfaction between SPLS and multiport laparoscopic surgery (MPLS) in colon cancer. Methods The multicentre randomised controlled SIngle-port versus MultiPort Laparoscopic surgEry (SIMPLE) trial included patients with colon cancer who underwent radical surgery at seven hospitals in South Korea. We performed a pre-planned secondary analysis of the QoL data of 359 patients from that trial. The QoL was surveyed using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 preoperatively and at 1, 3, 6, and 12 months postoperatively. Patient satisfaction was measured with a 5-point questionnaire at these postoperative time points. Results Overall, 145 and 147 patients were included in the SPLS and MPLS groups, respectively. Most QoL domains were similar between the groups. In the subgroup analysis of patients without adjuvant chemotherapy, patients in the SPLS group presented with significantly better global health status (p = 0.017), fatigue (p = 0.047), and pain (p = 0.005) scores and tended to have improved physical (p = 0.055), emotional (p = 0.064), and social (p = 0.081) functioning, with marginal significance at 1 month postoperatively, compared to those in the MPLS group. Patient satisfaction regarding surgery (p = 0.002) and appearance of the abdominal scar (p = 0.002) was significantly higher with SPLS than with MPLS at 12 months postoperatively. Conclusion Patients who underwent SPLS without adjuvant chemotherapy had better global health status, fatigue status, and pain at 1 month postoperatively; however, these improvements were minimal and temporary. In the near future, the effect of SPLS on postoperative QoL should be confirmed through a randomised controlled trial targeting the QoL in colon cancer patients.

  • Do postoperative telemedicine interventions with a communication feature
           reduce emergency department visits and readmissions'—a systematic
           review and meta-analysis

    • Free pre-print version: Loading...

      Abstract: Introduction Emergency department (ED) visits and readmissions after surgery are common and represent a significant cost-burden on the healthcare system. A notable portion of these unplanned visits are the result of expected complications or normal recovery after surgery, suggesting that improved coordination and communication in the outpatient setting could potentially prevent these. Telemedicine can improve patient–physician communication and as such may have a role in limiting unplanned emergency department visits and readmissions in postoperative patients. Methods Major electronic databases were searched for randomized controlled trials and cohort studies in surgical patients examining the effect of postoperative telemedicine interventions with a communication feature on 30-day readmissions and emergency department visits as compared to current standard postoperative follow-up. All surgical subspecialties were included. Two independent reviewers assessed eligibility, extracted data, and evaluated risk of bias using standardized tools. Our primary outcomes of interest were 30-day ED visits and readmissions. Our secondary outcomes were patient satisfaction with the intervention. Results 29 studies were included in the final analysis. Fourteen studies were RCTs, and the remaining fifteen were cohort studies. Eighteen studies reported 30-day ED visit as an outcome. There was no overall reduction in 30-day ED visit in the telemedicine group (RR: 0.89, 95%CI: 0.70–1.12). Twenty-two studies reported 30-day readmission as an outcome. The overall pooled estimate did not show a difference in this outcome (RR: 0.90, 95%CI: 0.74–1.09). Fifteen studies reported a metric of patient satisfaction regarding utilization of the telemedicine intervention. All studies demonstrated high levels of satisfaction (> 80%) with the telemedicine intervention. Discussion This review fails to demonstrate a clear reduction ED visits and readmissions to support use of a telemedicine intervention across the board. This may be in part explained by significant heterogeneity in the proportions of potentially preventable visits in each surgical specialty. As such, targeting interventions to specific surgical settings may prove most useful.

  • Impact of the COVID-19 pandemic on an interdisciplinary endoscopy unit in
           a German “hotspot” area: a single center experience

    • Free pre-print version: Loading...

      Abstract: Background and study aims Since December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of coronavirus disease 2019 (COVID-19), has posed a pandemic threat to global health and has challenged health care system in all affected countries. Patients and methods This is a combined study including a descriptive part about the changes in the daily work routine of an Interdisciplinary Endoscopic Unit (IEU) and a prospective analysis of patients tested positive for SARS-CoV-2 who required endoscopic interventions. Conclusively, we present the finding of a point-prevalence analysis in the staff of the IEU. Results We present effects of the COVID-19-related restructuring of processes in our interdisciplinary endoscopy unit (IEU) with respect to cancelation of examinations, relocation of staff to other departments, impact of SARS-CoV-2 on medical staff of the IEU, and supply of protective clothing. Additionally, we analyzed the cohort of COVID-19 patients: Sixteen endoscopic interventions were done in ten patients. In all patients with confirmed infection with SARS-CoV-2, emergency endoscopies were required for relevant bleeding situations. Re-endoscopies were required only in critically ill COVID-19 patients. Conclusions The restructuring of processes in the IEU was feasible in short time, effective, and can also be applied broadly at least in developed countries [Garbe et al. in Gastroenterology 159:778–780, 2020; Repici A, Pace F, Gabbiadini R, Colombo M, Hassan C, Dinelli M, Group IG-CW, Maselli R, Spadaccini M, Mutignani M, Gabbrielli A, Signorelli C, Spada C, Leoni P, Fabbri C, Segato S, Gaffuri N, Mangiavillano B, Radaelli F, Salerno R, Bargiggia S, Maroni L, Benedetti A, Occhipinti P, De Grazia F, Ferraris L, Cengia G, Greco S, Alvisi C, Scarcelli A, De Luca L, Cereatti F, Testoni PA, Mingotto R, Aragona G, Manes G, Beretta P, Amvrosiadis G, Cennamo V, Lella F, Missale G, Lagoussis P, Triossi O, Giovanardi M, De Roberto G, Cantu P, Buscarini E, Anderloni A, Carrara S, Fugazza A, Galtieri PA, Pellegatta G, Antonelli G, Rosch T, Sharma P (2020) Endoscopy units and the COVID-19 Outbreak: a Multi-Center Experience from Italy.

  • Impact of the Endoscopic Surgical Skill Qualification System on the safety
           of laparoscopic gastrectomy for gastric cancer

    • Free pre-print version: Loading...

      Abstract: Background We hypothesized that the Endoscopic Surgical Skill Qualification System (ESSQS) can shorten operative time, resulting in a decrease in postoperative morbidity. Here, we aimed to clarify whether ESSQS-qualified surgeons could decrease the incidence of complications. Methods Between January 2009 and June 2019, 1042 patients diagnosed with both clinical and pathological Stage ≤ III gastric cancer and undergoing LG were enrolled. In all LG procedures involving ESSQS-qualified surgeons, these served as the operator or the instructive assistant. The short-term outcomes were retrospectively compared between the ESSQS-qualified and the non-ESSQS-qualified surgeons using a propensity-score matched analysis. Results After propensity-score matching, 321 patients were included in each group. No significant differences were observed in morbidity rate, and length of hospitalization following surgery, although the non-ESSQS-qualified surgeon group had a significantly longer total operative time (Non-ESSQS-qualified group, 368 [170–779] min vs. ESSQS-qualified group, 316 [147–772] min; p < 0.001), and larger estimated blood loss (Non-ESSQS-qualified group, 28 [0–702] mL vs. ESSQS-qualified group 25, [0–1069] mL; p = 0.042). Multivariate analysis revealed that operative time ≥ 360 min (OR 1.818 [1.069–3.094], p = 0.027) was identified as the only significant independent risk factor determining morbidity. Conclusions The incidence of postoperative morbidity did not differ between patients operated by the qualified and nonqualified surgeons, as long as ESSQS-qualified surgeons provide intraoperative instructions.

  • Clinical results after biliary drainage by endoscopic retrograde
           cholangiopancreatography for analysis of metastatic cancer survival and
           prognostic factors

    • Free pre-print version: Loading...

      Abstract: Background Malignant biliary obstruction secondary to metastatic cancer is associated with poor prognosis. To the best of our knowledge, no previous study has investigated long-term survival and associated prognostic factors after biliary endoscopic retrograde cholangiopancreatography (ERCP) drainage for obstruction jaundice secondary to various types of metastatic cancer. Methods This retrospective study included 60 patients who underwent biliary ERCP drainage for obstructive jaundice secondary to metastatic cancer at two hospitals during the period from November 2012 to December 2019. Multivariate analysis was conducted to identify independent prognostic factors. Results Biliary drainage was successfully achieved in 55 (91.7%) patients, 37 of whom received subsequent treatment. Overall median survival time was 133 days after stent placement. The overall survival (OS) rates after ERCP drainage were significantly better in the post-drainage treatment group than in the post-drainage untreated group (239 days vs. 45 days, p < 0.001). Good ECOG performance status before drainage, albumin level ≥ 35 g/L, successful drainage, absence of ascites, and post-drainage treatment were identified as factors of improved survival in univariate analysis. ECOG performance status and post-drainage treatment were independent predictors of OS in multivariate analysis. Conclusions We showed that stent placement with ERCP was a safe and effective treatment method for patients with malignant biliary obstruction caused by metastatic cancer and may be preferred over percutaneous transhepatic biliary drainage. Post-drainage treatment and a good ECOG performance status were predictors of better prognosis.

  • Endoscopic papillectomy; a retrospective international multicenter cohort
           study with long-term follow-up

    • Free pre-print version: Loading...

      Abstract: Background Endoscopic papillectomy (EP) is considered a relatively safe and minimally invasive treatment for papillary adenomas. In the literature a significant risk for local recurrence is described. The aim of this study was to evaluate long-term recurrence rates and time-to-recurrence. Additionally, risk factors for recurrence, malignancy and adverse events were studied. Methods This is a retrospective study in consecutive patients with papillary adenomas who underwent EP in two tertiary referral hospitals between 2001 and 2018. Primary outcome was recurrence in patients with at least 1-year endoscopic follow-up. Secondary outcomes were surgery free survival, adverse events, and mortality within 30 days after the index procedure. Results A total of 259 patients were found eligible [median age 66 years, 130 male (50.2%)]. Forty-three patients were known with familial adenomatous polyposis (FAP) (16.6%). At least 1-year endoscopic follow-up was available in 154 patients with a total follow-up of 586 person-years and median of 40 months [interquartile range (IQR) 25–75]. Recurrence occurred in 24 cases (15.6%) of which 8 were known with FAP, leading to a recurrence incidence rate of 4.1 per 100 person-years with a median time-to-recurrence of 29 months (IQR 14.75–59.5). Fifty-three patients underwent at least 5-year follow-up, in 6 (11.3%) of them recurrence was encountered after 5 years of which four were known with FAP. No risk factors for recurrence could be identified. Adverse events occurred in 50/259 patients (19.3%). One patient died within 30 days after the procedure. Papillary stenosis occurred in 19/259 (7.3%) of the patients. There were no cases of malignant degeneration during follow-up. Conclusions Recurrence after EP occurs in a significant proportion of patients and occurs even 5 years after EP. This emphasizes the need for long-term follow-up. We advise to consider at least 5-year follow-up in case of a sporadic adenoma, unless comorbidity makes follow-up clinically irrelevant.

  • Achieving the critical view of safety in the difficult laparoscopic
           cholecystectomy: a prospective study of predictors of failure

    • Free pre-print version: Loading...

      Abstract: Background Bile duct injury rates for laparoscopic cholecystectomy (LC) remain higher than during open cholecystectomy. The “culture of safety” concept is based on demonstrating the critical view of safety (CVS) and/or correctly interpreting intraoperative cholangiography (IOC). However, the CVS may not always be achievable due to difficult anatomy or pathology. Safety may be enhanced if surgeons assess difficulties objectively, recognise instances where a CVS is unachievable and be familiar with recovery strategies. Aims and methods A prospective study was conducted to evaluate the achievability of the CVS during all consecutive LC performed over four years. The primary aim was to study the association between the inability to obtain the CVS and an objective measure of operative difficulty. The secondary aim was to identify preoperative and operative predictors indicating the use of alternate strategies to complete the operation safely. Results The study included 1060 consecutive LC. The median age was 53 years, male to female ratio was 1:2.1 and 54.9% were emergency admissions. CVS was obtained in 84.2%, the majority being difficulty grade I or II (70.7%). Displaying the CVS failed in 167 LC (15.8%): including 55.6% of all difficulty grade IV LC and 92.3% of difficulty grade V. There were no biliary injuries or conversions. Conclusion All three components of the critical view of safety could not be demonstrated in one out of 6 consecutive laparoscopic cholecystectomies. Preoperative factors and operative difficulty grading can predict cases where the CVS may not be achievable. Adapting instrument selection and alternate dissection strategies would then need to be considered.
