Factors predicting a positive capsule endoscopy in past overt obscure gastrointestinal bleeding: a multicenter retrospective study.

Objectives: Capsule endoscopy (CE) remains the examination of choice for the investigation of obscure gastrointestinal bleeding. Although the factors predicting positive CE findings in the overall obscure gastrointestinal bleeding have been investigated, the clinical characteristics that predict a positive CE in patients with past overt obscure gastrointestinal bleeding (OOGIB) have not been systematically studied.

Methods: Between September 2004 and December 2013, 262 patients underwent CE for evaluation of past OOGIB after negative upper and lower endoscopy, and other diagnostic modalities.

The role of capsule endoscopy in the evaluation and treatment of obscure-overt gastrointestinal bleeding during daily clinical practice: a prospective multicenter study.

Objective: Capsule endoscopy (CE) is most commonly performed to evaluate obscure gastrointestinal bleeding (GIB). However, at present the role of CE in patients with obscure-overt GIB especially during daily clinical practice is unknown. The aim of the present study was to investigate the diagnostic yield and the impact of CE on the management of patients with obscure-overt GIB.

A prospective comparative study of blended and pure coagulation current in endoscopic mucosal resection of large sessile colorectal polyps.

Background: The aim of this study was to compare pure coagulation and blended current in the resection of large colorectal sessile polyps (SPs).

Patients And Methods: Between January 2009 and June 2012, 84 patients (45 men, 39 women; median age 66 y; range, 42 to 88 y) with large colorectal SPs (diameter ≥2 cm) were randomized in 1:1 ratio to undergo treatment by the "lift and cut" piecemeal resection technique. A total of 43 blended current subjects (group A) were well matched to 41 pure coagulation current subjects (group B), with a median lesion size of 3.

Optimisation of Radiation Exposure to Gastroenterologists and Patients during Therapeutic ERCP.

This study intended to optimize the radiation doses for gastroenterologists and patients during therapeutic endoscopic retrograde cholangiopancreatography (ERCP) and to compare the doses based on available data obtained by other researchers. A total of 153 patients were studied in two Gastroenterology Departments, (group A, 111; group B, 42). Thermoluminescent dosimeters (TLD) were used to measure the staff and patients entrance surface air kerma (ESAK) at different body sites.

Prophylactic clip application before endoscopic resection of large pedunculated colorectal polyps in patients receiving anticoagulation or antiplatelet medications.

Background: The aim of the present study was to evaluate the safety of prophylactic endoclipping before resection of large pedunculated colorectal polyps in patients with uninterrupted anticoagulation or antiplatelet therapy.

Patients And Methods: In a single tertiary referral center, patients with normal coagulation parameters and those with uninterrupted anticoagulation or antiplatelet medications, who underwent prophylactic endoclipping before resection of large pedunculated colorectal polyps (polyp's head diameter >10 mm), were evaluated retrospectively. Demographic, clinical, and laboratory parameters, polyp characteristics, number of clips used for endoclipping, histology of resected polyps, the polypectomy technique, and postpolypectomy complications were recorded and compared.
