BACKGROUND: The role of laparoscopic surgery in the treatment of transverse colon cancer remains controversial in Japan. The aim of the present study is to review the short term outcomes of the laparoscopic surgery for transverse colon cancer.
METHODS: Most cases were advanced cases. Our principle of the procedure is to perform D3 dissection and complete resection of mesocolon (CRM) for the advanced cases. Thirty-one patients underwent laparoscopic surgery for transverse colon cancer in our hospital from February 2010 to November 2014. We conducted partial resection of transverse colon, right hemicolectomy and left hemicolectomy depending on the location and stage of the tumor. We reviewed short term outcomes including operative time, blood loss, postoperative complication, conversion to open surgery, recurrence after resection.
RESULTS: Patients with transverse colon cancer underwent 22 (70%) partial resection of transvers colon, 6 (20%) right hemicolectomy and 3 (10%) left hemicolectomy. Median operative time was 240 min (125-555 min). Median blood loss was 100 mg (5-700 mg). Rate of postoperative complications was 12% (lymph fistula: 10%, ileus: 3%). Conversion rate to open surgery was 3% because of the invasion to duodenum. So far no recurrence case has been observed.
CONCLUSION: Laparoscopic resection of transverse colon cancer is technically feasible and not associated with a significantly higher rate of complications compered with laparoscopic resection for other colon cancer.
