Multiple microaneurysms of the superior hemorrhoidal artery: unusual recurrent massive rectal bleeding: report of a case.

A case of massive rectal bleeding in a 38-year-old male patient from a previously unreported source is presented. Multiple microaneurysms affecting the rectum were demonstrated on an inferior mesenteric artery angiogram. The importance of angiography both for diagnosis and potential therapy in patients with continuous active lower gastrointestinal bleeding is emphasized.

Esophageal variceal ligation by reloading with inexpensive hemorrhoidal O-ring--is an overtube necessary?

The overtube is the major cause for severe complications during endoscopic variceal ligation with a single-shot ligator. This retrospective study was designed to examine the necessity of the placement of an overtube during elective endoscopic variceal ligation. Thirty-one sessions in 18 patients were analyzed. An overtube was inserted using an over-the-scope technique in 11 sessions (group 1) but was omitted in 20 sessions (group II). The complications, technical difficulties, and operating time were analyzed. Child's grading, the size of the esophageal varices, and the number of rubber bands deployed were comparable in both groups. There was a significantly longer operating time (p < 0.01) and more oropharyngeal injury (p = 0.03) in group I than in group II. Mid esophageal injury, which was associated with resistance in withdrawing the gastroscope from the overtube, occurred in 55% of sessions in group I but in 0% of session in group II. In conclusion, the use of an overtube is associated with more complications, and it can be omitted during elective endoscopic variceal ligation.
