Study on the relationship between microbial composition within obstructive biliary stents and the severity of obstruction and duration of stent placement.

Biliary stent occlusion is due, in part, to biofilm formation by bacteria. However, previous culture-based approaches may not have revealed all microorganisms on the surface. Twenty-seven patients underwent endoscopic retrograde biliary drainage for the removal or replacement of plastic biliary stents.

Contribution of Capsule Endoscopy Early in a Bleeding Episode to Treatment of Small Bowel Angioectasia: A Case Report.

: Recent advances in endoscopic devices such as small bowel capsule endoscopy and balloon-assisted endoscopy have improved the level of medical care for small bowel bleeding. However, treating small bowel angioectasia remains challenging because repeated intermittent bleeding can occur from the multiple minute lesions (about 1 mm in size) that develop in a synchronous and metachronous manner. Here, we report a case of small bowel angioectasia in which capsule endoscopy performed early in a bleeding episode contributed to treatment.

Megaesophagus and Megaduodenum Found Incidentally on a Routine Chest Radiograph During a Health Examination.

Chronic idiopathic intestinal pseudo-obstruction (CIIP) caused by impaired intestinal peristalsis leads to intestinal obstructive symptoms. A 20-year-old man had marked esophageal dilatation that was found incidentally on chest radiography during a health examination. Chest/abdominal contrast-enhanced computed tomography and endoscopy showed marked esophageal and duodenal dilatation without mechanical obstruction.

Mesalazine formulation intolerance due to suspected excipient allergy in the treatment of ulcerative colitis: a case report.

Mesalazine formulations are essential for treating ulcerative colitis (UC), and intolerance to these formulations complicates the treatment of this condition. Some cases of mesalazine formulation intolerance are caused by the excipients rather than the active ingredient mesalazine. Therefore, mesalazine administration can be continued in such cases by changing the mesalazine formulation.
