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

Background: 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. Case Summary: A 66-year-old man with suspected small bowel bleeding underwent small bowel capsule endoscopy and balloon-assisted endoscopy with argon plasma coagulation hemostasis for a small intestinal angioectasia. Because small bowel bleeding recurred intermittently after the treatment, small bowel capsule endoscopy and balloon-assisted endoscopy were repeated when there was no bleeding, but no abnormalities were found. Subsequent small bowel capsule endoscopy during a bleeding episode revealed bloody intestinal fluid in the proximal small intestine. Peroral balloon-assisted endoscopy was performed 2 days after SBCE for detailed observation of the small intestinal mucosa at the suspected bleeding site, and there a 1-mm Dieulafoy's lesion with no active bleeding was identified. We performed argon plasma coagulation, and no bleeding was observed thereafter. Conclusions: Small bowel capsule endoscopy immediately after bleeding onset can identify the bleeding source of multiple minute lesions in small bowel angioectasia.

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. Upper gastrointestinal series and high-resolution esophageal manometry revealed absent peristalsis in the dilated part. CIIP was suspected in the patient's father, suggesting familial CIIP. The patient likely had signs of pre-onset CIIP. This is the first case of suspected CIIP in which detailed gastrointestinal tract examinations were performed before symptoms appeared.

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. This report describes a case of intolerance to mesalazine in which UC was effectively treated by switching mesalazine formulations. A drug-induced lymphocyte stimulation test suggested that allergy to the additive povidone was the cause of mesalazine formulation intolerance. This is the first case study to identify an additive that caused mesalazine formulation intolerance.
