Abstract
Purpose: Mesenteric embolization is an integral part in the management of acute lower gastrointestinal (GI) bleeding. The aim of this study was to highlight our experience after adopting mesenteric embolization in the management of acute lower GI hemorrhage.
Methods: A retrospective review of all cases of mesenteric embolization for acute lower GI bleeding from October 2007 to August 2012 was performed.
Results: Twenty-seven patients with a median age of 73 years (range, 31 to 86 years) formed the study group. More than half (n = 16, 59.3%) of the patients were on either antiplatelet and/or anticoagulant therapy. The underlying etiology included diverticular disease (n = 9), neoplasms (n = 5) and postprocedural complications (n = 6). The colon was the most common bleeding site and was seen in 21 patients (left, 10; right, 11). The median hemoglobin prior to the embolization was 8.6 g/dL (6.1 to 12.6 g/dL). A 100% technical success rate with immediate cessation of hemorrhage at the end of the session was achieved. There were three clinical failures (11.1%) in our series. Two patients re-bled, and both underwent a successful repeat embolization. The only patient who developed an infarcted bowel following embolization underwent an emergency operation and died one week later. There were no factors that predicted clinical failure.
Conclusion: Mesenteric embolization for acute lower GI bleeding can be safely performed and is associated with a high clinical success rate in most patients. A repeat embolization can be considered in selected cases, but postembolization ischemia is associated with bad outcomes.
