Role of Endoscopy in GERD
- Abstract: Publication date: March 2014
  Source:Gastroenterology Clinics of North America, Volume 43, Issue 1
  Author(s): Virender K. Sharma
  
  Teaser Endoscopy is commonly performed for the diagnosis and management of gastroesophageal reflux disease (GERD). Endoscopy allows the physician to evaluate esophageal mucosa for evidence of esophagitis and Barrett esophagus, to obtain mucosal biopsies for evaluation of such conditions as eosinophilic esophagitis and diagnosis and grading of Barrett esophagus, and to apply various therapies. In a patient with suboptimal response to GERD therapy, endoscopy excludes other etiologies as a cause of patients’ symptoms. Newer endoscopic therapies for GERD are available or are in development. Advances in imaging techniques in development will improve the diagnostic yield of endoscopy and may replace the need for mucosal biopsies.

  Author(s): Sami R. Achem , Kenneth R. DeVault
  
  Teaser Gastroesophageal reflux disease is a common disorder in all patients but a particular problem in the elderly, for whom the disease often presents with advanced mucosal damage and other complications. Symptoms are also not as reliable an indication of disease severity in older patients. Likewise, therapy is more difficult because of potential side effects and drug interactions.

Barium Esophagram Does It Have a Role in Gastroesophageal Reflux Disease'
- Abstract: Publication date: Available online 7 January 2014
  Source:Gastroenterology Clinics of North America
  Author(s): Mark E. Baker , David M. Einstein
  
  Teaser The barium esophagram is an integral part of the assessment and management of patients with gastroesophageal reflux disease (GERD) before, and especially after, antireflux procedures. While many of the findings on the examination can be identified with endosocopy, a gastric emptying study and an esophageal motility examination, the barium esophagram is better at demonstrating the anatomic findings after anti-reflux surgery, especially in symptomatic patients. These complementary examinations, when taken as a whole, fully evaluate a patient with suspected GERD as well as symptomatic patients after antireflux procedures.

Surgical Treatment of GERD Where Have We Been and Where Are We Going'
- Abstract: Publication date: Available online 3 January 2014
  Source:Gastroenterology Clinics of North America
  Author(s): David Kim , Vic Velanovich
  
  Teaser Surgical management of gastroesophageal reflux disease has evolved from relatively invasive procedures requiring open laparotomy or thoracotomy to minimally invasive laparoscopic techniques. Although side effects may still occur, with careful patient selection and good technique, the overall symptomatic control leads to satisfaction rates in the 90% range. Unfortunately, the next evolution to endoluminal techniques has not been as successful. Reliable devices are still awaited that consistently produce long-term symptomatic relief with correction of pathologic reflux. However, newer laparoscopically placed devices hold promise in achieving equivalent symptomatic relief with fewer side effects. Clinical trials are still forthcoming.

Medical Treatments of GERD The Old and New
- Abstract: Publication date: Available online 31 December 2013
  Source:Gastroenterology Clinics of North America
  Author(s): Marcelo F. Vela
  
  Teaser The mainstay of pharmacological therapy for GERD is gastric acid suppression with proton pump inhibitors (PPIs), which are superior to histamine-2 receptor antagonists for healing erosive esophagitis and achieving symptomatic relief. However, up to one-third of patients may not respond to PPI therapy, creating the need for alternative treatments. Potential approaches include transient lower esophageal sphincter relaxation inhibitors; augmentation esophageal defense mechanisms by improving esophageal clearance or enhancing epithelial repair, and modulation of sensory pathways responsible for GERD symptoms. This review discusses the effectiveness of acid suppression and the data on alternative pharmacological approaches for the treatment of GERD.

Acid and Nonacid Reflux Monitoring
- Abstract: Publication date: Available online 27 December 2013

  Author(s): Dustin A. Carlson , John E. Pandolfino
  
  Teaser Detection of acid and nonacid reflux using esophageal reflux monitoring, which includes conventional and wireless pH monitoring and pH impedance, can be a valuable diagnostic tool when used appropriately in the assessment of patients with gastroesophageal reflux disease. Reflux monitoring may be especially helpful if a management change is desired, such as when initial or empirical treatment is ineffective. However, each of these methods has its limitations, which need to be accounted for in their clinical use. Indications, test performance, interpretation, and clinical applications of esophageal reflux monitoring, as well as their limitations, are discussed in this review.

Obesity and GERD
- Abstract: Publication date: Available online 27 December 2013

  Author(s): Paul Chang , Frank Friedenberg
  
  Teaser Epidemiologic data have demonstrated that obesity is an important risk factor for the development of gastroesophageal reflux disease (GERD). There is also accumulating data that obesity is associated with complications related to longstanding reflux such as erosive esophagitis, Barrett esophagus, and esophageal adenocarcinoma. Central obesity, rather than body mass index, appears to be more closely associated with these complications. Surgical data are confounded by the concomitant repair of prevalent hiatal hernias in many patients.

Esophageal Manometry in Gastroesophageal Reflux Disease
- Abstract: Publication date: Available online 28 December 2013
  Source:Gastroenterology Clinics of North America
  Author(s): Michael Mello , C. Prakash Gyawali
  
  Teaser High-resolution manometry (HRM) allows nuanced evaluation of esophageal motor function, and more accurate evaluation of lower esophageal sphincter (LES) function, in comparison with conventional manometry. Pathophysiologic correlates of gastroesophageal reflux disease (GERD) and esophageal peristaltic performance are well addressed by this technique. HRM may alter the surgical decision by assessment of esophageal peristaltic function and exclusion of esophageal outflow obstruction before antireflux surgery. Provocative testing during HRM may assess esophageal smooth muscle peristaltic reserve, and help predict the likelihood of transit symptoms following antireflux surgery. HRM represents a continuously evolving new technology that compliments the evaluation and management of GERD.

Pathophysiology of Gastroesophageal Reflux Disease
- Abstract: Publication date: Available online 27 December 2013

  Teaser Gastroesophageal reflux disease (GERD) is one of the most common digestive diseases in the Western world, with typical symptoms, such as heartburn, regurgitation, or retrosternal pain, reported by 15% to 20% of the general population. The pathophysiology of GERD is multifactorial. Our understanding of these factors has significantly improved in recent years, with increased understanding of the acid pocket and hiatal hernia and how these factors interact. Although our insight has significantly increased over the past years, more studies are required to better understand symptom generation in GERD, especially in patients with therapy-resistant symptoms.

Symptom Predictability in Gastroesophageal Reflux Disease and Role of Proton Pump Inhibitor Test
- Abstract: Publication date: Available online 27 December 2013
  Source:Gastroenterology Clinics of North America
  Author(s): David S. Estores
  
  Teaser There are problems with the definition, assessment, and measurement of gastroesophageal reflux disease (GERD). The Reflux Disease Questionnaire and the GERD questionnaire are patient-reported outcome (PRO) measures for use in a primary care setting, which are easy to use and are validated. There is no widely accepted definition of a proton pump inhibitor test and performance of the test in the clinical setting is not standardized. The use of the PRO measures in primary care with predetermined cutoff values may help to reduce the cost of diagnosing GERD and increasing rates of response for evaluated patients to acid suppression.

Epidemiology of Gastroesophageal Reflux Disease
- Abstract: Publication date: Available online 27 December 2013
  Source:Gastroenterology Clinics of North America
  Author(s): Joel H. Rubenstein , Joan W. Chen
  
  Teaser The prevalence of gastroesophageal reflux disease (GERD) symptoms increased approximately 50% until the mid-1990s, when it plateaued. The incidence of complications related to GERD including hospitalization, esophageal strictures, esophageal adenocarcinoma, and mortality also increased during that time period, but the increase in esophageal adenocarcinoma has since slowed, and the incidence of strictures has decreased since the mid-1990s. GERD is responsible for the greatest direct costs in the United States of any gastrointestinal disease, and most of those expenditures are for pharmacotherapy. Risk factors for GERD include obesity, poor diet, lack of physical activity, consumption of tobacco and alcohol, and respiratory diseases.

Extraesophageal Presentations of GERD Where is the Science'
- Abstract: Publication date: Available online 28 December 2013
  Source:Gastroenterology Clinics of North America
  Author(s): Ryan D. Madanick
  
  Teaser This article reviews the evaluation and management of patients with suspected extraesophageal manifestations of gastroesophageal reflux disease, such as asthma, chronic cough, and laryngitis, which are commonly encountered in gastroenterology practices. Otolaryngologists and gastroenterologists commonly disagree upon the underlying cause for complaints in patients with one of the suspected extraesophageal reflux syndromes. The accuracy of diagnostic tests (laryngoscopy, endoscopy, and pH- or pH-impedance monitoring) for patients with suspected extraesophageal manifestations of gastroesophageal reflux disease is suboptimal. An empiric trial of proton pump inhibitors in patients without alarm features can help some patients, but the response to therapy is variable.

  Author(s): Pablo A. Bejarano , Marylise Boutros , Mariana Berho
  
  Teaser Diagnosis, follow up, and treatment of anal intraepithelial neoplasia are complex and not standardized. This may be partly caused by poor communication of biopsy and cytology findings between pathologists and clinicians as a result of a disparate and confusing terminology used to classify these lesions. This article focuses on general aspects of epidemiology and on clarifying the current terminology of intraepithelial squamous neoplasia, its relationship with human papilloma virus infection, and the current methods that exist to diagnose and treat this condition.

Management of Radiation Proctitis
- Abstract: Publication date: December 2013

  Author(s): Ankit Sarin , Bashar Safar
  
  Teaser Radiation damage to the rectum following radiotherapy for pelvic malignancies can range from acute dose-limiting side effects to major morbidity affecting health-related quality of life. No standard guidelines exist for diagnosis and management of radiation proctitis. This article reviews the definitions, staging, and clinical features of radiation proctitis, and summarizes the modalities available for the treatment of acute and chronic radiation proctitis. Because of the paucity of well-controlled, blinded, randomized studies, it is not possible to fully assess the comparative efficacy of the different approaches to management. However, the evidence and rationale for use of the different strategies are presented.

Surgical Management of Fecal Incontinence
- Abstract: Publication date: Available online 6 November 2013
  Source:Gastroenterology Clinics of North America
  Author(s): Joshua I.S. Bleier , Brian R. Kann
  
  Teaser The surgical approach to treating fecal incontinence is complex. After optimal medical management has failed, surgery remains the best option for restoring function. Patient factors, such as prior surgery, anatomic derangements, and degree of incontinence, help inform the astute surgeon regarding the most appropriate option. Many varied approaches to surgical management are available, ranging from more conservative approaches, such as anal canal bulking agents and neuromodulation, to more aggressive approaches, including sphincter repair, anal cerclage techniques, and muscle transposition. Efficacy and morbidity of these approaches also range widely, and this article presents the data and operative considerations for these approaches.

  Teaser Anal fissure is a common anorectal disorder resulting in anal pain and bleeding. Fissures can either heal spontaneously and be classified as acute, or persist for 6 or more weeks and be classified as chronic, ultimately necessitating treatment. Anal stenosis is a challenging problem most commonly resulting from trauma, such as excisional hemorrhoidectomy. This frustrating issue for the patient is equally as challenging to the surgeon. This article reviews these 2 anorectal disorders, covering their etiology, mechanism of disease, diagnosis, and algorithm of management.

  Author(s): Jason F. Hall
  
  Teaser Complaints secondary to hemorrhoidal disease have been treated by health care providers for centuries. Most symptoms referable to hemorrhoidal disease can be managed nonoperatively. When symptoms do not respond to medical therapy, procedural intervention is recommended. Surgical hemorrhoidectomy is usually reserved for patients who are refractory to or unable to tolerate office procedures. This article reviews the pathophysiology of hemorrhoidal disease and the most commonly used techniques for the nonoperative and operative palliation of hemorrhoidal complaints.

Colonoscopic Polypectomy Current Techniques and Controversies
- Abstract: Publication date: September 2013
  Source:Gastroenterology Clinics of North America, Volume 42, Issue 3
  Author(s): David G. Hewett
  
  Teaser Colonoscopic polypectomy is fundamental to effective colonoscopy. Through its impact on the polyp-cancer sequence, colonoscopic polypectomy reduces colorectal cancer incidence and mortality. Because it eliminates electrosurgical risk, cold snaring has emerged as the preferred technique for most small and all diminutive polyps. Few clinical trial data are available on the effectiveness and safety of specific techniques. Polypectomy technique seems highly variable between endoscopists, with some techniques more effective than others are. Further research is needed to investigate operator variation in polypectomy outcomes and establish an evidence base for best practice.

Water-aided Colonoscopy
- Abstract: Publication date: September 2013
  Source:Gastroenterology Clinics of North America, Volume 42, Issue 3
  Author(s): Felix W. Leung
  
  Teaser Water-aided methods for colonoscopy include the established water immersion and the recent novel modification of water exchange. Water immersion entails the use of water as an adjunct to air insufflations to facilitate insertion. Water exchange evolved from water immersion to facilitate completion of colonoscopy without discomfort in unsedated patients. Infused water is removed predominantly during insertion rather than withdrawal. A higher adenoma detection rate has been reported with water exchange. Aggregate data of randomized controlled trials suggest that water exchange may be superior to water immersion in attenuating colonoscopy discomfort and optimizing adenoma detection, particularly in the proximal colon.

  Teaser Advancements in image technology have allowed recognition of mucosal architecture in more detail and may improve adenoma detection. This review provides a technical overview on individual imaging technologies and their effect on detection of adenomas. Only high-definition endoscopy has been shown to improve detection of small adenomas. None of the digital chromoendoscopy technologies improves adenoma detection. Limited studies on autoimmunfluorescence imaging in conjunction with high-definition endoscopy may improve detection of small adenomas.

Cap-Assisted Colonoscopy
- Abstract: Publication date: September 2013
  Source:Gastroenterology Clinics of North America, Volume 42, Issue 3
  Author(s): Amit Rastogi
  
  Teaser Cap-assisted colonoscopy is a simple, practical, and inexpensive technique that serves several useful purposes in enhancing the performance of colonoscopy. It helps improve polyp detection by its ability to visualize otherwise blind mucosal areas on the proximal aspects of folds and flexures, although its effect on adenoma detection is inconsistent. By helping navigate the colon more efficiently, it facilitates intubation of the cecum faster, with lesser patient discomfort. Cap-assisted colonoscopy can be tried as a salvage procedure in cases of failed cecal intubation with regular colonoscopy and can be of assistance during polypectomy, especially for polyps located on the proximal aspects of folds.

Retroview Colonoscopy
- Abstract: Publication date: September 2013
  Source:Gastroenterology Clinics of North America, Volume 42, Issue 3
  Author(s): Jerome D. Waye
  
  Teaser A retroview in the colon permits an 11–25% increase in the adenoma detection rate when compared with a standard straight forward view during colonoscopy. This can often be accomplished in the rectum or the proximal colon by using dial controls and shaft manipulation to turn the tip of a standard colonoscope 180°. A special slim caliber instrument, the “Third Eye Retroscope” (a backward viewing device) has been developed which is inserted through the working channel of a colonoscope. New colonoscopes are being developed that have the capability of side vision with accompanying light illumination which, with wide angle lenses, provide an almost complete retroview of the colon.

Chromocolonoscopy

  Teaser “Chromocolonoscopy is the process of endoscopically examining the colon mucosa after it has been stained with dye. The goal is to allow the endoscopist to identify subtle features in the mucosa, such as morphologically flat polyps or crypt patterns. Studies examining the efficacy of chromocolonoscopy to identify adenomas missed by conventional colonoscopy have shown that although chromocolonoscopy increases polyp yield, most additional lesions are small in size. Staining can also help in differentiating neoplastic from non-neoplastic polyps. Perhaps the most useful aspect of chromocolonoscopy is increasing the yield for dysplasia in patients undergoing colonoscopy for inflammatory bowel disease surveillance.”

Optimal Withdrawal and Examination in Colonoscopy
- Abstract: Publication date: Available online 15 June 2013

  Author(s): Douglas K. Rex
  
  Teaser The primary goal of most colonoscopies, whether performed for screening, surveillance, or diagnostic examinations (those performed for symptoms or positive screening tests other than colonoscopy) is the detection of neoplasia and its subsequent removal by either endoscopic polypectomy or referral for surgical resection. Unfortunately, colonoscopy has proved to be a highly operator-dependent procedure with regard to detection. Variable detection results in some of the cancers that occur in the interval before the next colonoscopy.
