Background and study aims  Re-commencement of bleeding (rebleeding) of colonic diverticula after endoscopic hemostasis is a clinical problem. This study aimed to examine whether endoscopic visibility of colonic diverticular bleeding affects the risk of rebleeding after endoscopic hemostasis. Patients and methods  We performed a retrospective review of endoscopic images and medical charts of p...

A Dieulafoy's lesion is a vascular abnormality consisting of a large caliber-persistent tortuous submucosal artery. A small mucosal defect with the eruption of this protruding vessel can cause bleeding. In fact, a Dieulafoy's lesion is a relatively rare but potentially life-threatening condition. It accounts for 1% to 2% of cases of acute gastrointestinal bleeding. Although there is no consensu...

A 79-year-old woman presented with hematemesis. As upper gastrointestinal tract bleeding was suspected, acute gastroduodenoscopy was performed. This showed reflux esophagitis with multiple ulcerations (Los Angeles classification grade D) and oozing hemorrhage (Forrest Ib) in the lower third of the esophagus (●" Fig.1a). The bleeding was originating from a large area of ulceration, so clipping o...

Mortality from acute variceal bleeding (AVB) has improved markedly over the last 2-3 decades due to increased specialisation and standardisation of medical and endoscopic practice culminating in the production of consensus guidance based on expert opinion. Nonetheless, despite greater exposure, training and endoscopic practices, 30-day mortality still remains high at around 30%. This is a refle...

doscopic variceal ligation. The Stieg− mann±Goff ligator works by pulling a string to deploy the band [1], but requires an overtube for multiple ligations. Saeed’s multishooter has the advantage of single insertion, pulling a single band at a time and is able to shoot six bands [2]. Most multishooters use a double thread, however, which hampers the en− doscopic view. Our single−thread system ha...
