A 16-year-old girl presented with hematochezia and abdominal pain. The patient developed a small bowel obstruction that required a laparotomy, which showed a segment of grossly infarcted small bowel with 3 perforations, localized abscesses, and creeping fat. Resection and an end-to-end anastomosis were performed. Pathologic examination showed underlying mesenteric venous thrombosis with no evidence of Crohn's disease. Hematology workup showed no evidence of a congenitally inherent hypercoagulable state. The use of oral contraceptives was the only predisposing factor identified.
