Hyun Seok Lee, Seong Woo Jeon, Hye Yoon Park, Seong Jae Yeo
Background and study aims Colonoscopy in the right colon is less effective than in the left colon in screening for colorectal cancer. The aim of this study was to prospectively evaluate the diagnostic value of retroflexion in the right colon. Patients and methods A total of 1020 patients undergoing screening or surveillance colonoscopy were enrolled. After the first cecal intubation, the scope was withdrawn from the cecum to the hepatic flexure in the standard forward view and all identified polyps were resected...

Background and study aim: There are no data comparing endoscopic ultrasound (EUS)-guided gallbladder drainage (EGBD) with percutaneous cholecystostomy as a treatment for patients with acute cholecystitis. Patients and methods: This was a 1 : 1 matched cohort study of all patients who were unfit for cholecystectomy and underwent EGBD or percutaneous cholecystostomy instead for the treatment of acute cholecystitis. The outcomes were matched for age, sex, and American Society of Anesthesiologists grade. Outcome measures included the technical and clinical success rates, adverse events, hospital stay, the number of unplanned admissions, and mortality...

Background and study aims: Duodenal endoscopic submucosal dissection (ESD) requires sophisticated endoscopic techniques because of a high rate of perforation. We introduced the pocket-creation method (PCM) of duodenal ESD to overcome difficulties. The aim of this study was to evaluate the safety and usefulness of ESD using the PCM for superficial tumors of the duodenum. Patients and methods: We performed ESD of 17 non-ampullary duodenal lesions using the conventional method and of 28 lesions using the PCM from 2006 to 2015 and retrospectively reviewed the results, comparing the PCM and the conventional method...

Background: Staple-line leak following laparoscopic sleeve gastrectomy is a dire adverse event. While the treatment of acute and early leaks is well established, there is still dispute regarding late and chronic leaks. We describe an endoscopic approach combining septotomy and sleeve stricture dilation for treating late/chronic leaks. Methods: Ten consecutive patients with late/chronic proximal leaks were treated at our center. The septum separating the sleeve lumen from the perigastric cavity was progressively dissected over several sessions and the downstream stricture was pneumatically dilated...

Background and aims: Endoscopic treatment of Barrett's esophagus (BE) consists of endoscopic resection of visible lesions followed by radiofrequency ablation (RFA) for any remaining flat BE. Because RFA is only justified in flat BE, detection of neoplastic lesions (high grade dysplasia [HGD] and early adenocarcinoma [EAC]) is crucial. We hypothesized that the detection of visible lesions containing HGD or EAC would be superior in BE expert centers compared with community hospitals, thereby supporting centralization of therapy for BE-related neoplasia...

Background and study aims: Colonoscopy should reliably intubate the cecum with minimal patient discomfort and without complications. Use of thinner endoscopes to overcome pain during the procedure has shown promise. However, the use of thinner scopes could lead to excess looping and difficulty with therapeutic procedures. The aim of this meta-analysis was to analyze the performance of ultrathin colonoscopes (UTC) and standard colonoscopes for routine colonoscopy. Patients and methods: We searched several electronic databases for all randomized controlled trials and nonrandomized (prospective) studies that compared the efficacies of UTC (diameter ≤ 9...

Background and study aim: Upper endoscopy is the most common method for the diagnosis of upper gastrointestinal tract diseases. The aim of this study was to determine whether premedication with simethicone or N-acetylcysteine improves mucosal visualization during upper endoscopy. Patients and methods: This was a randomized, double-blind, placebo-controlled study of 297 patients scheduled for upper endoscopy who were premedicated 15 - 30 minutes before the procedure with: 100 mL of water (placebo, group A); water plus 100 mg simethicone (group B); water plus 100 mg simethicone plus 600 mg N-acetylcysteine (group C)...

Background and study aims: Endoscopic resection is a curative treatment option for large nonpedunculated colorectal polyps (LNPCPs). Endoscopic submucosal dissection (ESD) allows en bloc resection but ESD experience is still limited outside Asia. The aim of our study was to evaluate the role of ESD in the treatment of early rectal neoplasia in a European center. Patients and methods: 330 patients referred for endoscopic resection of rectal LNPCPs were included prospectively. Results: ESD was performed for 302 LNPCPs (median diameter 40 mm)...

Endoscopic submucosal dissection (ESD) is known to provide superior results in terms of en bloc and/or R0 resection compared with endoscopic mucosal resection. Therefore, ESD is also expected to provide superior clinical outcomes in terms of the need for supplementary surgery after endoscopic treatment. However, whether or not the clinical gain to the patient is sufficiently large to justify the cost and risk of ESD remains to be further evaluated.

Background and study aims: Guidelines recommend surveillance endoscopy with both forward- and side-viewing endoscopes to identify duodenal and ampullary adenomas in patients with familial adenomatous polyposis (FAP). We hypothesized that both the duodenum and the ampulla of Vater can be completely visualized during cap-assisted forward-viewing endoscopy. Patients and methods: A total of 40 patients with FAP underwent forward-viewing endoscopy with a short cap attached to the tip of the gastroscope, with the aim of visualizing both the duodenum and the ampulla of Vater...
