Two-port hand-assisted laparoscopic surgery for the 2-stage treatment of a complete bowel obstruction by left colon cancer: a case report.

A 69-year-old woman presented to her local clinic with vomiting and abdominal distension. Since a bowel obstruction by left colon cancer was suspected due to a marked dilation of the transverse colon, she was referred to our hospital. On admission, an enema disclosed a complete obstruction at the splenic flexure of the colon. An emergency operation was performed, and a temporary loop colostomy was fashioned on the left side of the transverse colon within the range of resection for 2-stage radical surgery. On hospital day 16, a left hemicolectomy D2 was performed by 2-port hand-assisted laparoscopic surgery (2P-HALS) using the stoma as the hand access site, and the tumor was resected along with the removal of the stoma. After surgery, a slight wound infection occurred at the hand access site, but this healed with conservative management. On day 36, she was discharged from hospital. The histological diagnosis was Type 2 circumferential well-differentiated adenocarcinoma with local peritoneal dissemination. Our experience suggests that 2-stage surgery combined with 2P-HALS is applicable even to a large obstructing left colon cancer. This method is less invasive, safe and achieves excellent results, including a good cosmetic outcome.
