Emergent Small Bowel Resection for Acute Mesenteric Ischemia

Between January 2007 and December 2019, we retrospectively reviewed patients who underwent emergent small bowel resection for nonmalignant lesions, by operative notes as well as by pathology results. We aimed to identify patients with AMI and intestinal gangrene. Patients who experienced intestinal gangrene and resection were included. The preoperative diagnosis of AMI was determined by contrast computed tomography (CT) scan. Gangrene of the bowel was confirmed by pathological findings. Patients without intestinal resection, intestinal gangrene, or preoperative contrast CT scans were all excluded. Patients with isolated ischemic colitis were also excluded. Patients with intestinal gangrene resulting from adhesion, abdominal wall hernia, internal herniation, or concurrent active malignancy were all excluded.
