Intraoperative video panendoscopy for diagnosing sites of chronic intestinal bleeding

Intraoperative video panendoscopy was performed in 14 patients with chronic, recurrent gastrointestinal bleeding. All of the study patients had undergone extensive and expensive diagnostic testing including multiple radiographic contrast studies of the gastrointestinal tract, upper and lower endoscopy, nuclear bleeding scans, and selective mesenteric angiography without definition of the bleeding source. Intraoperative video panendoscopy, employing a segmental advance and look technique, allowed visualization and transillumination of the entire gut and identified mucosal disease in 13 patients (93 percent). Angiodysplasia of the colon and small intestine was the most common pathologic finding. Intraoperative video panendoscopy significantly influenced the operation performed in 13 patients (93 percent). Postoperative complications were minimal, with none being directly attributable to intraoperative video panendoscopy. Bleeding was totally controlled in 10 patients (71 percent) during a mean follow-up period of 25 months. Intraoperative video panendoscopy is a valuable technique for assisting in the management of the patient with recurrent gastrointestinal bleeding.
