[Recurrent rectorrhagia caused by angiodysplasia of the colon localized exclusively by scintigraphy with Tc-99m red blood cells]. / Rectorragia recidivante por angiodisplasia de colon, localizada exclusivamente mediante gammagrafía con 99mTc-hematíes.

ABSTRACT

A case of angiodysplasia of the colon with clinical manifestation of massive rectal bleeding is presented. The activity and the severity of the life-threatening bleeding episode led to emergency exploratory laparotomy with intraoperative colonoscopy which was not diagnostic. Three years later, following multiple recurrent bleeding episodes and non diagnostic explorations, the localization of the hemorrhage was obtained by abdominal scintigraphy with 99mTc-red blood cells. Surgical removal of the affected area achieved definitive cure.
