Postpolypectomy bleeding: incidence, risk factors, prevention, and management.

Endoscopic polypectomy is at the forefront of colorectal cancer (CRC) prevention. However, endoscopic polypectomy is not completely free of complications, with bleeding being one of the most common complications encountered. In view of the ongoing campaign to introduce colorectal cancer screening to the population, addressing the issue of colonoscopic complications, and postpolypectomy bleeding (PPB) in particular is becoming more important.

Diagnostic yield and clinical impact of wireless capsule endoscopy in patients with chronic abdominal pain with or without diarrhea: a Greek multicenter study.

Background: Wireless capsule endoscopy has become the gold standard for the examination of small bowel. However, its role in the evaluation of patients suffering from chronic abdominal pain is not yet clearly defined. We conducted an open-label prospective multi-center study to evaluate the yield and clinical outcome of capsule endoscopy in patients with chronic abdominal pain with/without diarrhea.

Endoscopic management of occluded biliary uncovered metal stents: a multicenter experience.

Aim: To compare diverse endoscopic interventions in the management of occluded uncovered self-expanding metal stents (SEMSs) that had been placed for palliative treatment of unresectable malignant biliary obstruction.

Methods: A retrospective review was undertaken in 4 tertiary endoscopic centers to determine optimal management of different types of occluded SEMSs. The technical success of performed treatment in occluded SEMSs, the patency of the stent, the need for re-intervention and the financial costs of each treatment were analyzed.

The use of endoclips in the treatment of nonvariceal gastrointestinal bleeding.

Acute nonvariceal gastrointestinal bleeding is the most common emergency managed by endoscopists and the endoscopic therapy has generally been recommended as the first-line treatment. Traditionally, endoscopic treatment included injections of epinephrine and sclerosing solutions or the use of thermocoagulation. In the last decade with the introduction of hemoclips and band ligators, we have witnessed a significant improvement in the clinical outcome of nonvariceal gastrointestinal bleeding.
