[A Case of Perforated Rectal Cancer with Laparoscopic Low Anterior Resection].

We report a case of perforated rectal cancer with laparoscopic low anterior resection. Case: A 60-year-old man was transported to the hospital with a chief complaint of sudden lower abdominal pain. Computed tomography revealed wall thickening of the upper rectum and free air localized around the rectum and fecal mass in the mesorectum. He was diagnosed with perforated rectal cancer. Because of the early onset, young age, and ascites confined to the pelvic floor, we decided to perform laparoscopic low anterior resection(D3 dissection). Intraabdominal observation revealed tumor in the upper rectum with a large rectal perforation 3 cm proximal to the tumor. By using gauze and suction, we were able to complete the surgery with ingenuity laparoscopically. The postoperative course was good, and he was discharged 9 days after surgery. Postoperative pathological examination revealed pT4apN0sM0, pStage Ⅱb. Adjuvant chemotherapy of 8 courses of capecitabine was performed. There has been no recurrence 3 years after surgery.
