Clip-assisted endoloop ligation of the mucosal defect after resection of colorectal polyps decreased postprocedural delayed bleeding.

Background: Postprocedural delayed bleeding (PDB) remains the most common major complication of colorectal polypectomy. Incomplete clip closure of mucosal defect and unclosed injured blood vessels in gaps between clips may be the risk factors for PDB.

Objectives: To observe whether completely no-gap closure of mucosal defect after polypectomy can reduce PDB occurrence.

Success and Safety of Needle Knife Papillotomy and Fistulotomy Based on Papillary Anatomy: A Prospective Controlled Trial.

Background: Needle knife papillotomy (NKP) and fistulotomy (NKF) are the two most commonly used rescue techniques for patients with difficult biliary cannulation (DBC). Anatomy of the major duodenal papillae (MDP) influences the optimal precut technique for biliary access. However, comparative studies of the success and safety of NKP and NKF based on the anatomy of MDP have been scarce.

Needle-knife papillotomy and fistulotomy improved the treatment outcome of patients with difficult biliary cannulation.

Background And Aims: Needle-knife papillotomy and fistulotomy (NKPF) is a new, modified technique designed for difficult biliary cannulation. The safety and efficacy of performing NKPF based on characteristics of main duodenal papilla (MDP) was evaluated.

Methods: We performed a retrospective review of consecutive patients with intact papilla who were established as candidates for therapeutic ERCP at tertiary referral center.

Clip closure of defect after endoscopic resection in patients with larger colorectal tumors decreased the adverse events.

Background: Clip closure of large colorectal mucosal defects may reduce the rate of adverse events in a cost-effective manner.

Objective: To assess the adverse events and outcomes of clip closure of defects after endoscopic resection in patients with large colorectal tumors.

Design: Prospective, randomized, controlled study.

Antimicrobial prophylaxis in patients with colorectal lesions undergoing endoscopic resection.

Aim: To investigate the effect of prophylaxis with antibiotics on clinical adverse events in patients who underwent endoscopic submucosal dissection (ESD) or endoscopic mucosal resection (EMR) for colorectal lesions.

Methods: From June 2011 to December 2013, a total of 428 patients were enrolled into the study, of which 214 patients admitted to hospital underwent EMR or ESD procedures. These patients were randomized to an antibiotic group, in which patients were given cefuroxime 1.
