Management of Malignant Large-Bowel Obstruction

Abstract

An otherwise healthy 59-year-old man presented to the emergency department with 2 weeks of narrowed stools, 5 days of obstipation, and 1 day of abdominal pain, nausea, and vomiting. Computed tomography revealed an obstructing sigmoid mass without evidence of metastatic disease, and the CEA was 1.2 ng/mL. Flexible sigmoidoscopy confirmed a circumferentially obstructing distal sigmoid neoplasm. Endoscopic stent placement was immediately followed by a firm distended abdomen. An upright radiograph obtained following the procedure demonstrated free intraperitoneal air. An emergent Hartmann procedure was performed for iatrogenic colon perforation in a patient with malignant obstruction and chronic dilation of the proximal colon.
