As the application of laparoscopic surgical technique in colorectal cancer surgery becomes more and more mature,it is favored by surgeons because of its high precision of operation and fast postoperative recovery.However,in the face of obese patients or patients with severe adhesions in the abdominal cavity,the conventional laparoscopic approach becomes particularly difficult.For these patients,it is important to seek a safer and more effective approach.Currently,there is no report of retroperitoneal approach for the treatment of sigmoid colon cancer.In this case,we report a female patient with sigmoid colon cancer who underwent successful D3 lymph node dissection with preservation of the left colonic artery via retroperitoneal approach.
