      BACKGROUND: Perforation is an uncommon but potentially devastating complication of colonoscopy. Surgical closure is the standard of care. Immediate endoluminal closure of a perforation would avoid the morbidity and mortality associated with general anesthesia, laparotomy, and surgical repair.

      OBJECTIVES: To evaluate the feasibility and safety of full-thickness endoscopic closure of colonic perforations with a prototype endoscopic suturing device, the Eagle Claw, in a porcine ...

      BACKGROUND: We hypothesized that magnetic resonance cholangiography (MRC) may have less accuracy for the diagnosis and the assessment of the severity of primary sclerosing cholangitis (PSC) than endoscopic retrograde cholangiography (ERC).

      OBJECTIVE: The aim of this study was to determine the diagnostic accuracy and interobserver agreement of both ERC and MRC in PSC.

      DESIGN: A case-control study.

      SETTING: University Hospital.

      PATIENTS: ERCs and MRCs of 36 patients with PSC and 51 ...

      Cholangiocarcinoma remains difficult to diagnose and is a major cause of death in patients with primary sclerosing cholangitis. Recently serum carcinoembryonic antigen and carbohydrate antigen 19-9 (CA 19-9) levels have been reported to improve diagnostic accuracy in patients with cholangiocarcinoma and primary sclerosing cholangitis. We reviewed our experience with cholangiocarcinoma complicating primary sclerosing cholangitis to identify clinical factors associated with ...

      BACKGROUND: Data regarding the incidence and severity of post-ERCP pancreatitis (PEP) are primarily from nonrandomized studies.

      OBJECTIVE: To determine the incidence, severity, and mortality of PEP from a systematic review of the placebo or no-stent arms of randomized, controlled trials (RCTs).

      DESIGN: MEDLINE, EMBASE, and Cochrane databases were searched to identify RCTs evaluating the efficacy of drugs and/or pancreatic stents to prevent PEP.

      SETTING: Systematic review of patients ...

      Background and AimEndoscopic ultrasound-guided biliary drainage (EGBD) may be a safe, alternative technique to percutaneous transhepatic biliary drainage (PTBD) in patients who fail ERCP. However, it is currently unknown how both techniques compare in terms of efficacy, safety, and cost. The aims of this study were to compare efficacy, safety, and cost of EGBD to that of PTBD.MethodsJaundiced patients with distal malignant biliary obstruction who underwent EGBD or PTBD after failed ERCP ...

      BACKGROUND & AIMS: Individuals with a strong family history of pancreatic cancer and persons with Peutz-Jeghers syndrome (PJS) have an increased risk for pancreatic cancer. This study screened for early pancreatic neoplasia and compared the pancreatic abnormalities in high-risk individuals and control subjects.

      METHODS: High-risk individuals with PJS or a strong family history of pancreatic cancer were prospectively evaluated with baseline and 12-month computed tomography (CT) scan and ...

      BACKGROUND: Although colonoscopy is currently the optimal method for detecting colorectal polyps, some are missed. The Third Eye Retroscope provides an additional retrograde view that may detect polyps behind folds.

      OBJECTIVE: To determine whether the addition of the Third Eye Retroscope to colonoscopy improves the adenoma detection rate.

      DESIGN: Prospective, multicenter, randomized, controlled trial.

      SETTING: Nine European and U.S. centers.

      PATIENTS: Of 448 enrolled subjects, 395 had ...

      Molecular markers of pancreatic neoplasia could aid in the evaluation of visible pancreatic lesions and indicate neoplasia invisible to imaging. We evaluated methylation-specific PCR (MSP) assays that detect aberrantly methylated DNA for their use as markers of pancreatic neoplasia. Methylation analysis was done on pancreatic juice collected endoscopically or surgically from 155 individuals with suspected pancreatic disease: 56 patients had pancreatic ductal adenocarcinoma, 17 had ...

      BACKGROUND AND STUDY AIMS: Placement of a pancreatic stent is recommended for the prevention of pancreatitis after endoscopic retrograde cholangiopancreatitis (ERCP) among high-risk patients. However, it is not known whether there is a particular feature of the pancreatic stent that is associated with a lower incidence of post-ERCP pancreatitis (PEP). This systematic review and network meta-analysis (NMA) aimed to examine whether a particular feature of pancreatic stents is associated ...

      BACKGROUND: Transgastric cholecystectomy is thought to technically and anatomically challenge a single entry flexible endoscopic approach.

      OBJECTIVES: To examine the feasibility of a transgastric-only cholecystectomy, endoscope performance in an upper-abdominal operation, and the usefulness of an offset gastrotomy.

      STUDY DESIGN: Animal survival study.

      SETTING: Animal research laboratory.

      PATIENTS: Six domestic pigs.

      MAIN OUTCOME MEASUREMENTS: Transgastric access to the gallbladder and ...

      BACKGROUND AND AIMS: There are limitations to enteral self-expandable metal stents and surgical gastrojejunostomy in the treatment of patients with gastric outlet obstruction (GOO). EUS-guided gastroenterostomy (EUS-GE) is a novel procedure that potentially offers long-lasting luminal patency without the risk of tumor ingrowth and/or overgrowth, while avoiding the morbidity of a surgical procedure. The aims of this study were to report the first U.S. clinical experience with EUS-GE in ...

      BACKGROUND AND AIMS: Endoscopic sleeve gastroplasty (ESG) reduces the gastric lumen to a size comparable with that of laparoscopic sleeve gastrectomy (LSG). However, there is a paucity of research comparing outcomes between the 2 procedures. Our study compared the 6-month weight loss outcomes and adverse events of ESG with LSG in a case-matched cohort.

      METHODS: We retrospectively reviewed prospectively collected data for patients undergoing ESG or LSG at a single academic center. Weight ...

      BACKGROUND: The aim of this study is to report a novel, multicenter experience with the diverticular peroral endoscopic myotomy (D-POEM) technique in the management of esophageal diverticula.

      METHODS: This is a multicenter, international, retrospective study involving three centers. D-POEM was performed using the principles of submucosal endoscopy.

      RESULTS: A total of 11 patients with an esophageal diverticulum (Zenker's 7, mid-esophagus 1, epiphrenic 3) were included. The mean size of ...

      BACKGROUND AND AIMS: The safety and efficacy of peroral endoscopic myotomy (POEM) when performed by gastroenterologists in the endoscopy unit are currently unknown. The aims of this study were to assess (1) the safety and efficacy of POEM in which all procedures were performed by 1 gastroenterologist in the endoscopy unit, and (2) the predictors of adverse events and nonresponse.

      METHODS: All consecutive patients who underwent POEM at 1 tertiary center were included. Clinical response ...
