Abstract
BackgroundAlthough indications for surgery in lower gastrointestinal bleeding (LGIB) are widely described, practice varies. This study was designed to assess outcomes of patients allowed to exceed traditional triggers for surgery because of LGIB. MethodsThis is a retrospective review of patients at an urban tertiary hospital over a 3-y period that had LGIB necessitating 99mTc-labeled red blood cell scintigraphy. Traditional indications for operative treatment of LGIB were defined as transfusion of >6U of packed red blood cells, hemodynamic instability, bleeding lasting >72h, and rebleeding after cessation of bleeding for >24h. ResultsOne hundred ninety-four LGIB patients had scintigraphy during the period of study with 180 meeting inclusion criteria. Fifty-six (31%) patients had at least one operative indication, and 32 (60%) were managed nonoperatively without a mortality. There were two (8.3%) mortalities in those who had operative management, one of which was because of exsanguination. Eighteen (32%) patients who met operative criteria were unlocalized. ConclusionsPatients with LGIB can be safely managed nonoperatively, even when the bleed is unlocalized and traditional indications for surgery are met. Exsanguinations because of LGIB treated nonoperatively are rare except in patients deemed not to be surgical candidates.
