[Role of multi-detector row computed tomography for localization of acute lower gastrointestinal bleeding].

Background/aims: Recent studies have shown good performance for the detection of sources of gastrointestinal bleeding using multi-detector row computed tomography (MDCT). However, there are limited reports about the role of MDCT for localization of acute lower gastrointestinal (GI) bleeding. The purpose of this study was to evaluate the role of MDCT for detection and localization of acute lower gastrointestinal bleeding.

Background: Endoscopic stone removal is difficult in patients with a Billroth II gastrectomy.

Objective: To evaluate the usefulness of a rotatable papillotome and large-balloon dilation for removing bile-duct stones in patients with a Billroth II gastrectomy.

Design: A case series.
