Efficacy and Safety of Endoscopic Submucosal Dissection for Superficial Gastric Neoplasms: A Latin American Cohort Study.

Background/aims: Endoscopic submucosal dissection (ESD) is the preferred technique for treating early gastric cancer (EGC). However, very few studies have been conducted in South America. This study aimed to assess the efficacy and safety of ESD for EGC.

Peroral endoscopic myotomy in a pediatric patient with refractory achalasia: a case report and review of the literature.

A 15-year-old male patient presented with dysphagia, regurgitation, weight loss and retrosternal pain. The diagnosis of achalasia was made 4 years before. The esophagogram revealed severe esophagus dilatation and the classic "bird-beak" termination.

Closure of colonic deep mural injury and perforation with endoclips.

Introduction: colorectal perforations are one of the most feared complications after performing an endoscopic resection. The use of endoclips is considered for the management of these complications.

Objectives: to evaluate the efficacy and safety of the use of endoclips in the management of perforations and deep mural injuries that occur after an endoscopic colorectal resection.

[Safety and efficacy of the use of self-expanding metal stents in the management ofunresectable malignant biliary stenosis].

Background: In recent years there has been an increase in the use of self-expanding metallic stents (SEMS) in patients with unresectable malignant stenosis of the bile duct. However, in Peru there are no reports on the safety and efficacy of this procedure.

Objective: To evaluate the safety and efficacy of the use of SEMS in the palliative management of malignant stenosis of the bile duct.

Fasciola hepatica in the common bile duct: spyglass visualization and endoscopic extraction.

We report the case of a 60-year-old Peruvian female who was admitted with abdominal pain and jaundice. Cholangioscopy revealed a leaf-like trematode, Fasciola hepatica. This trematode was extracted with a Dormia's basket via endoscopic retrograde cholangiopancreatography (ERCP).

[Large balloon dilation for removal of choledocholithiasis difficult to extract: clinical experience].

Objective: The aim of this study was to report the initial experience of the combined use of biliary sphincterotomy plus balloon dilatation of the papilla for management of large stones.

Materials And Methods: Design: Retrospective, descriptive. This study included 18 patients in whom a hydrostatic dilatation of the papilla with large balloons was performed between June 2012 and April 2014.

[Perception of pain during sigmoidoscopy flexible as an additional diagnostic method for irritable bowel syndrome].

Introduction: Visceral hypersensitivity has been proposed as a biological marker of Irritable bowel syndrome (IBS).

Objective: To evaluate the pain perception during sigmoidoscopy using a visual analog scale of pain in patients with or without IBS, and to assess the pain perception as diagnostic criteria for IBS. We further assessed the sensitivity, specificity and diagnostic efficiency of pain scores to diagnose IBS.
