  • Perioperative use of immunosuppressive medications in patients with
           Crohn's disease in the new "biological era"

    • Authors: Lightner AL; Shen B.
      First page: 165
      Abstract: AbstractCrohn’s disease (CD) is characterized by transmural inflammation of the gastrointestinal tract leading to inflammatory, stricturing and/or and fistulizing disease. Once a patient develops medically refractory disease, mechanical obstruction, fistulizing disease or perforation, surgery is indicated. Unfortunately, surgery is not curative in most cases, underscoring the importance of bowel preservation and adequate perioperative medical management. As many of the medications used to treat CD are immunosuppressive, the concern for postoperative infectious complications and anastomotic healing are particularly concerning; these concerns have to be balanced with preventing and treating residual or recurrent disease. We herein review the available literature and make recommendations regarding the preoperative, perioperative and postoperative administration of immunosuppressive medications in the current era of biological therapy for CD. Standardized algorithms for perioperative medical management would greatly assist future research for optimizing surgical outcomes and preventing disease recurrence in the future.

  • Systematic review of mixed cryoglobulinemia associated with hepatitis E
           virus infection: association or causation'

    • Authors: Bazerbachi F; Leise MD, Watt KD, et al.
      First page: 178
      Abstract: AbstractBackground and aim: Mixed cryoglobulinemia (MC) has been associated with several viral infections, and chronic hepatitis C is recognized as a major cause. MC associated with hepatitis E virus (HEV) has been described and little is known about this rare association. The aim of this study is to perform a systematic review of MC associated with HEV, and examine the presence of a causal relationship.Methods: An experienced librarian conducted a search of databases from each database’s inception to 12 December 2016 based on a priori criteria. The risk of bias was assessed, and Hill’s criteria were applied to determine causality.Results: Five publications met inclusion criteria, with a total of 15 cases. Three studies had low, one low to moderate and one moderate risk of bias. Median age was 43 years, and all patients came from Western Europe. Two patients were immunocompetent, while 13 were immunosuppressed, post solid organ transplant and had chronic hepatitis E. Renal involvement was observed in seven patients, mild to moderately severe cryoglobulinemic disease in one patient and severe cryoglobulinemic disease in three patients. One patient improved spontaneously, and another was treated with immunosuppressant reduction leading to viral clearance. Ten patients treated with peg-interferon or ribavirin for 3 months achieved loss of cryoglobulinemia and end-of-treatment response, but sustained virologic response was reported and achieved in two. Immunosuppressant achieved loss of cryoglobulinemia in three patients. One case of chronic renal failure, three cases of end-stage renal disease and one death were observed. Five of the nine Hill’s criteria were fulfilled.Conclusion: MC has been described with HEV infection. A causal relationship between HEV infection and cryoglobulinemia is highly probable.

  • Variceal bleeding in cirrhotic patients

    • Authors: Mallet M; Rudler M, Thabut D.
      First page: 185
      Abstract: AbstractVariceal bleeding is one of the major causes of death in cirrhotic patients. The management during the acute phase and the secondary prophylaxis is well defined. Recent recommendations (2015 Baveno VI expert consensus) are available and should be followed for an optimal management, which must be performed as an emergency in a liver or general intensive-care unit. It is based on the early administration of a vasoactive drug (before endoscopy), an antibiotic prophylaxis and a restrictive transfusion strategy (hemoglobin target of 7 g/dL). The endoscopic treatment is based on band ligations. Sclerotherapy should be abandoned. In the most severe patients (Child Pugh C or B with active bleeding during initial endoscopy), transjugular intrahepatic portosystemic shunt (TIPS) should be performed within 72 hours after admission to minimize the risk of rebleeding. Secondary prophylaxis is based on the association of non-selective beta-blockers (NSBBs) and repeated band ligations. TIPS should be considered when bleeding reoccurs in spite of a well-conducted secondary prophylaxis or when NSBBs are poorly tolerated. It should also be considered when bleeding is refractory.

  • Selection of a cut-off for high- and low-methane producers using a
           spot-methane breath test: results from a large north American dataset of
           hydrogen, methane and carbon dioxide measurements in breath

    • Authors: Gottlieb K; Le C, Wacher V, et al.
      First page: 193
      Abstract: AbstractBackground: Levels of breath methane, together with breath hydrogen, are determined by means of repeated collections of both, following ingestion of a carbohydrate substrate, at 15–20 minutes intervals, until 10 samples have been obtained. The frequent sampling is required to capture a rise of hydrogen emissions, which typically occur later in the test: in contrast, methane levels are typically elevated at baseline. If methane emissions represent the principal objective of the test, a spot methane test (i.e. a single-time-point sample taken after an overnight fast without administration of substrate) may be sufficient.Methods: We analysed 10-sample lactulose breath test data from 11 674 consecutive unique subjects who submitted samples to Commonwealth Laboratories (Salem, MA, USA) from sites in all of the states of the USA over a one-year period. The North American Consensus (NAC) guidelines criteria for breath testing served as a reference standard.Results: The overall prevalence of methane-positive subjects (by NAC criteria) was 20.4%, based on corrected methane results, and 18.9% based on raw data. In our USA dataset, the optimal cut-off level to maximize sensitivity and specificity was ≥4 ppm CH4, 94.5% [confidence interval (CI): 93.5–95.4%] and 95.0% (CI: 94.6–95.5%), respectively. The use of a correction factor (CF) (5% CO2 as numerator) led to reclassifications CH4-high to CH4-low in 0.7 % and CH4-low to CH4-high in 2.1%.Conclusions: A cut-off value for methane at baseline of either ≥4 ppm, as in our USA dataset, or ≥ 5 ppm, as described in a single institution study, are both highly accurate in identifying subjects at baseline that would be diagnosed as ‘methane-positive’ in a 10-sample lactulose breath test for small intestinal bacterial overgrowth.

  • Fecal microbiota transplantation for Clostridium difficile infection in
           patients with ileal pouches

    • Authors: Lan N; Ashburn J, Shen B.
      First page: 200
      Abstract: AbstractBackground:Clostridium difficile infection (CDI) in patients with ileal pouch-anal anastomosis (IPAA) has been increasingly recognized. The aim of this study was to evaluate the outcome of fecal microbiota transplantation (FMT) in patients with pouch and CDI.Methods: All consecutive patients that underwent FMT for CDI from 2012 to 2016 were extracted from our IRB-approved, prospectively maintained Registry of Pouch Disorders. The primary outcome was negative stool tests for Clostridium difficile after FMT and the secondary outcomes were symptomatic and endoscopic responses.Results: A total of 13 patients were included in this study, with 10 being Caucasian males (76.9%). All patients had underlying ulcerative colitis for J pouch surgery. After a mean of 2.8±0.8 courses of antibiotic treatments was given and failed, 22 sessions of FMT were administered with an average of 1.7±1.1 sessions each. Within the 22 sessions, 16 were given via pouchoscopy, 4 via esophagogastroduodenoscopy and 2 via enemas. All patients tested negative on C. difficile polymerase chain reaction (PCR) after the initial FMT with a total of 7/12 (58.3%) documented patients showed symptomatic improvements and 3/11 (27.3%) patients showed endoscopic improvement according to the modified Pouchitis Disease Activity Index. During the follow-up of 1.2±1.1 years, there were a total of five patients (38.5%) that had recurrence after the successful initial treatment and four of them were successfully treated again with FMT.Conclusions: FMT appeared to be effective in eradication of CDI in patients with ileal pouches. However, FMT had a modest impact on endoscopic inflammation and recurrence after FMT and recurrence was common.

  • Real world experience with pegylated interferon and ribavirin in hepatitis
           C genotype 1 population with favourable IL28B polymorphism

    • Authors: Ekstrom V; Kumar R, Zhao Y, et al.
      First page: 208
      Abstract: AbstractBackground and aim: Conventional hepatitis C treatment using pegylated interferon (PEG-IFN) and ribavirin is associated with significant side effects. IL28B polymorphism can predict response to treatment, with CC genotype having a better response. ITPA gene deficiency protects against clinically significant anaemia induced by treatment. The purpose of this study was to determine IL28B polymorphism and ITPA variation among hepatitis C genotype 1 patients who have undergone therapy with PEG-IFN and ribavirin and their association with sustained viral response (SVR).Methods: All hepatitis C genotype 1 patients who had been treated with PEG-IFN and ribavirin over the past 10 years were identified by available medical records and were contacted by letter of invitation to participate in the study. Blood samples for IL28B and ITPA genotyping were obtained. Medical records were reviewed for verification of treatment response, development of anaemia and if treatment reduction was required during the treatment.Results: A total of 61 patients with hepatitis C genotype 1 were treated with PEG-IFN and ribavirin, of whom 42 agreed to participate in the study. Mean age was 45.6±12.9 years at time of treatment, and 83.3% of patients were males. Thirty-three (78.6%) had IL28B CC genotype, of whom 25 (75.8%) obtained SVR compared with only 3 of 9 (33.3%) non C/C genotype patients who achieved SVR (P=0.041). Eleven (26.1%) patients had ITPA AC genotype, and 30 (71.4%) had CC genotype. There was no statistically significant difference between ITPA AC and CC genotypes in predicting clinically significant anaemia (45.5% vs 63.3%, P=0.302). Even among patients who developed anaemia, 70.8% still managed to achieve SVR. Treatment reduction also had no impact on SVR.Conclusion: Hepatitis C genotype 1 patients should be informed of the response rate for treatment with PEG-IFN and ribavirin in a population with favourable IL28B genotype before consideration of newer therapeutic options.

  • Healthcare utilization and costs associated with cholangiocarcinoma

    • Authors: Wadhwa V; Jobanputra Y, Thota PN, et al.
      First page: 213
      Abstract: AbstractBackground and aims. Cholangiocarcinoma is a rare but devastating malignancy associated with a poor prognosis and a high mortality rate. With the recent advances in detection and treatment, it is unclear if the incidence and outcomes of cholangiocarcinoma are improving in the United States. The aim of this study was to evaluate the trends in the incidence, costs and mortality rates of cholangiocarcinoma- related hospital admissions in the USA.Methods. We utilized the National Inpatient Sample Database (NIS) from 1997–2012 for all patients in whom cholangiocarcinoma (ICD-9 code 155.1, 156) was the principal discharge diagnosis. The temporal trends in the number of hospital admissions, length of stay and, hospitalization costs along with mortality rates over the study period were determined by using regression analysis for trends.Results. There was a significant increase in the number of hospital admissions for cholangiocarcinoma as the principal diagnosis from 1997 to 2012 (10 357 vs 11 970, P<0.001). The mean length of stay for cholangiocarcinoma decreased by 17 % between 1997 and 2012 from 9.5 days to 7.9 days (P<0.001). However, during the same period, the mean hospital charges per patient (adjusted for inflation) increased 113.25% from $36 460 in 1997 to $77 753 in 2012. The in-hospital mortality rate decreased from 9.3% in 1997 to 6.4% in 2012 (P<0.001).Conclusions. There was a significant increase in the number of hospital admissions and associated costs from cholangiocarcinoma in the USA between 1997 and 2012. However, this was accompanied by a decrease in the inpatient mortality rates from cholangiocarcinoma.

  • Identification of the distinguishing features of Crohn’s disease and
           ischemic colitis using computed tomographic enterography

    • Authors: Chen M; Remer EM, Liu X, et al.
      First page: 219
      Abstract: AbstractBackground and aims: The differential diagnosis between Crohn’s disease (CD) and ischemic colitis (ISC) is important as their clinical management is different. ISC can easily be misdiagnosed as CD, especially in elderly populations. The distinctive radiographic features of the two disease entities have not been investigated. The aim of this study is to assess the utility of computed tomographic enterography (CTE) in the differential diagnosis between CD and ISC.Methods: Patients with confirmed CD and ISC were identified through an electronic medical record search of the Cleveland Clinic Foundation. Patients who had undergone CTE, with or without concurrent colonoscopy and histopathological specimens, were included in this study. CTE images were blindly re-reviewed by an expert gastrointestinal radiologist. The sensitivities, specificities, accuracies and positive and negative predictive values for each of the CTE findings in differentiating CD from ISC were estimated. Kappa coefficients (κ) were calculated to measure diagnosis agreement between CTE and the reference standard.Results: A total of 34 eligible patients were included in this study with 17 having CD and 17 having ISC. In differentiating CD from ISC, the presence of mucosal hyperenhancement and absence of the “target sign” on CTE showed a sensitivity of 100% each for CD, while the two radiographic features yielded a low specificity of 35.3% and 76.5%, respectively. The presence of stricture had a lower sensitivity of 64.7% for the detection of CD but had a high specificity of 100%. In distinguishing CD from ISC, the accuracy of presence of mucosal hyperenhancement, stricture and absence of target sign were 67.7%, 82.4% and 88.2%, respectively. The combination of the presence of mucosal hyperenhancement and the absence of the target sign achieved an accuracy of 100% for distinguishing CD from ISC. There was a good correlation between CTE and the reference standard for distinguishing CD from ISC (κ = 0.882).Conclusions: CTE appeared to be clinically useful in distinguishing CD from ISC.

  • Rectal cancer restaging using 3D CUBE vs. 2D T2-weighted technique after
           neoadjuvant therapy: a diagnostic study

    • Authors: Cao W; Lian Y, Liu D, et al.
      First page: 226
      Abstract: AbstractObjective. This study aimed to compare the accuracy of rectal cancer restaging after neoadjuvant therapy with 3D CUBE sequence with 2D T2-weighted fast spin-echo (FSE) sequence.Methods. This retrospective study comprised 72 patients with rectal cancer confirmed by colonoscopy and biopsy. After neoadjuvant therapy, all patients underwent pelvic magnetic resonance imaging (MRI) examination at 1.5T MRI sequences including a single coronal 3D CUBE T2-weighted FSE sequence with 1.4 mm thickness and a 2D T2-weighted FSE sequence in the sagittal, coronal and axial planes with 5 mm thickness. The total acquisition time of the two sequences was recorded. Results were compared with postsurgical pathology (gold standard). The diagnostic accuracy was evaluated; and receiver operating characteristic (ROC) curves and the area under the curves (AUC) were calculated.Results. The T category staging accuracy of 3D T2WI and 2D T2WI was 81.9% and 72.2%, respectively, for reviewer 1 and 86.1% and 75.0% for reviewer 2. The AUC of 3D was higher than that of 2D (0.878 vs. 0.783 for reader 1 and 0.905 vs. 0.796 for reader 2; both P < 0.05) when judging whether the tumor broke through the muscle layer. There was no significant difference between 3D and 2D in judging whether lymph nodes were malignant (AUC 0.719 vs. 0.698 for reader 1 and 0.740 vs. 0.698 for reader 2; both P > 0.05). There were no significant differences in the visibility of the rectal wall layer, tumor lesion and the overall image quality (all P > 0.05). Compared with 2D sequences, the 3D sequence had shorter acquisition time and higher signal intensity ratio (both P < 0.05).Conclusion. 3D CUBE T2-weighted sequences offer better diagnostic accuracy in rectal cancer restaging after neoadjuvant therapy when compared with 2D T2-weighted FSE sequences; it has a shorter scanning time and more versatility of orientation reconstruction.

  • Ammonia level at admission predicts in-hospital mortality for patients
           with alcoholic hepatitis

    • Authors: Ravi S; Bade KS, Hasanin M, et al.
      First page: 232
      Abstract: AbstractObjective. Alcoholic hepatitis (AH), a unique clinical syndrome among patients with chronic and active alcohol use, is associated with high short-term mortality. An elevated ammonia level is associated with mortality in patients with acute liver failure; however, its impact in AH has not been well-studied.Methods. A retrospective study was performed on patients admitted to a tertiary-care hospital with the discharge diagnosis of AH. Patients meeting criteria for AH were included in the final data analysis. Multivariate logistic regression models were built to examine the impact of serum ammonia in predicting in-hospital mortality (IHM) and 30-day mortality (TDM). Subgroup analysis was also performed, which was limited to patients who had hepatic encephalopathy.Results. Of the 105 AH patients included, 26 (25%) died during the initial hospitalization. Among the 79 patients who survived initial hospitalization, 30 (39%) died within 30 days. Information about ammonia levels at admission was available for 82 patients. Of these, 25 patients had IHM and significantly higher ammonia level (97 vs. 69 μmol/L, P < 0.01). Among the 57 who survived hospitalization, ammonia levels were not significantly different (71 vs. 67 μmol/L, P = 0.69) in patients with and without TDM. The addition of ammonia to the multivariate regression models including age, sex, cirrhosis, treatment and model for end-stage liver disease (MELD) score improved the C statistics for IHM from 0.708 to 0.801 and for TDM from 0.756 to 0.766, respectively. These results were identical, even when limited to patients with hepatic encephalopathy.Conclusion. AH patients with elevated ammonia levels at admission have higher IHM; however, they do not seem to play a significant role in 30-day mortality for patients who survived hospitalization.

  • Wandering spleen: a surgical enigma

    • Authors: Puranik A; Mehra R, Chauhan S, et al.
      First page: 241
      Abstract: AbstractWandering spleen, also referred to as ‘ptotic spleen’, is a rare clinical condition characterized by splenic migration form its normal left hypochondrial position to any other abdominal or pelvic position. Among the multifactorial etiologies proposed, laxity of the spleen’s primary supporting ligaments is the most agreed-upon hypothesis. We present one rare case of wandering spleen in an 11-year-old girl who presented with recurrent abdominal pain with no localizing features. Her abdominal examination revealed an intra-abdominal left iliac fossa lump with restricted mobility, which was confirmed as a wandering spleen by abdominal sonography and contrast-enhanced computed tomography. Intraoperatively, an infarcted spleen was encountered with tortuous, elongated, torsional splenic pedicle and a single dense adhesive band with descending colon. Splenectomy was offered to the patient. Post-operatively, the patient is healthy and symptom free at one-year follow-up. The rare clinical diagnosis of this condition, particularly in the paediatric age-group, makes it an enigma for the surgical world.

  • A diagnostic dilemma: acute abdomen presenting as segmental arterial
           mediolysis masked by a ruptured hepatocellular carcinoma

    • Authors: Liao C; Kuo W, Huang E, et al.
      First page: 244
      Abstract: AbstractA 65-year-old male was brought to our hospital with right upper abdominal fullness sensation and recent body weight loss of about 3 kg. The patient had developed episodes of melena following progressive abdominal muscular guarding and drop of haemoglobin level to 6.3 g/dL. An abdominal computed tomography scan disclosed a ruptured hepatocellular cell carcinoma. A segmental arterial mediolysis was found on the superior mesenteric artery in the process of repairing the ruptured right hepatic artery with the assistance of angiography. Transarterial embolization was carried out and permanent haemostasis was achieved.
