Totally laparoscopic colectomy with intracorporeal anastomosis for colonic liposarcoma: A case report

Liposarcoma is a type of soft tissue sarcoma. Primary colonic liposarcomas are extremely rare. An 86-year-old man with diarrhea and anorexia visited our outpatient clinic at Okayama City Hospital. Colonoscopy and computed tomography imaging revealed a large submucosal tumor in the descending colon with a maximum diameter of approximately 10 cm. He underwent totally laparoscopic left hemicolectomy with intracorporeal anastomosis. The histopathological diagnosis was a well-differentiated liposarcoma without lymph node metastases. The patient's postoperative course was uneventful. We herein report a rare case of totally laparoscopic colectomy with intracorporeal anastomosis in an elderly patient with colonic liposarcoma.
