Use of intraoperative radionuclide study and colonoscopy in gastrointestinal hemorrhage.
Tc-99m labeled red cell imaging is used in the diagnosis and localization of gastrointestinal hemorrhage. A patient in whom a preoperative scan was positive in the right paraumbilical region is discussed. Intraoperative Tc-99m labeled red cell imaging was used in conjunction with colonoscopy, and the site of active bleeding was found in the proximal transverse colon, which had been displaced downward because of adhesions.
