Abstract
A 68-year-old man presented with abdominal pain and bloody stool. Rectal cancer was identified on lower gastrointestinal endoscopy, and further investigations resulted in a diagnosis of T3N2M0c Stage IIIb. Preoperative contrast-enhanced computed tomography (CT) showed that the patient also had Leriche syndrome, but this was asymptomatic, and imaging also showed that blood was supplied to the legs and intraperitoneal organs via highly developed intraperitoneal collateral flow. Laparoscopic low anterior resection was carried out without revascularization. There were no perioperative complications, and the patient was discharged on postoperative Day 7. It was possible to safely perform laparoscopic surgery for rectal cancer in a patient with Leriche syndrome.
