ABSTRACT
Angiodysplasia of small bowel is uncommon and frequently undiagnosed and presents a taxing surgical problem. It is usually diagnosed for unexplained gastrointestinal bleeding. For the surgeon, the main technical problem is that the lesion is impalpable, and invisible to the naked eye, so it usually cannot be identified unless bleeds actively at the time of surgery. Arteriography gives a little information about wax and wane pattern of bleeding in the lesion. Endoscopy is often unfruitful because the majority of lesions are submucosal and rarely exceed a few millimeters in diameter. Transillumination of the intestinal wall from inside of the lumen to the outside in a dark room can define the precise vascular anatomy of the wall. The delicate lesion of the angiodysplasia can be identified by this transillumination method. We described a simple intraoperstive endoscopic translllumination technique used successfully to identify an angiodysplasia in the small bovwel prior to the bowel resecion. This report summarized our experience and review of literature.

The bleeding duodenal varices ia uncommon and frequeintly present a difficult diagnostic problem While the bleeding duodenal varices is a complication of portal hypertension, the possibility of bleeding duodenal varices in the absence of eaophageal varix bleeding should be kept mind. For the surgeon, the mikin technical problem is that even when identified by frequently impalpable, and invisible to the naked eye unless they are actively bleeding at the time of surgery. We described simple intra-operative endoscopic technique successfully to identify and bleeding varices in the duodenal third portion prior to the partial duodenal resection. This report summarized our experience and review of literature.

Angiodysplsia of the small bowel is uncommon, but provably remains frequently undiagnosed. In the small intestine, angiodysplasia presents a taxing surgical problem and is uauslly diagnosed for unexplained gastrointestinal bleeding. For the surgeon, the main technical problem is that even when identified by frequently impalpable, and invisible to the naked eye unless they are actively bleeding at the time of surgery. Ensocopy is often unfruitful because the majority of lesions are submucosal and rarely exceed a few milimeters in diameter. We described a simple intraoperative endoscopic transillumination technique used successfully to identify an angiodysplasia in the jejunum prior to the small bowel resection. This report summarized our experience and review of literature.
