Intraoperative enteroscopy is a valuable method for localizing gastrointestinal bleeding of obscure origin. The insertion and manipulation of an endoscope through an enterotomy, however, may result in significant trauma to the intestinal wall, as well as contamination of the abdominal cavity. We have devised a new technique for the introduction of the endoscope that lessens trauma to the bowel wall and allows a complete enteroscopy with minimal contamination.
