Short bowel syndrome after near total enterectomy in an elderly patient: case report and review of the literature

Abstract

Acute mesenteric ischemia (AMI) is a rare but highly lethal vascular emergency resulting from the abrupt interruption of intestinal blood flow. In advanced stages, extensive bowel necrosis may require near total enterectomy, leading to short bowel syndrome and permanent dependence on parenteral nutrition. An 86-year-old woman with atrial fibrillation and multiple cardiometabolic comorbidities presented with acute abdominal pain, nausea, and vomiting. Initial laboratory findings revealed marked leukocytosis and severe systemic inflammation (CRP: 21.0 mg/L). Computed tomography (CT) angiography demonstrated impaired perfusion of the superior mesenteric artery. Emergency laparotomy confirmed extensive jejunoileal ischemic necrosis, necessitating near total enterectomy with stapled jejunoileal anastomosis. Second-look surgery revealed progressive ischemia of the ileocecal region and right colon, requiring extended right hemicolectomy. Postoperatively, the patient was managed with total parenteral nutrition and intensive supportive care. Despite temporary stabilization and discharge on home parenteral nutrition, she died six months later. AMI complicated by short bowel syndrome is associated with poor prognosis in elderly patients. Persistent systemic inflammation, progressive organ dysfunction, and intestinal failure remain major determinants of adverse long-term outcomes, highlighting the critical importance of early diagnosis, prompt surgical intervention, and multidisciplinary postoperative management.
