Abstract
We report the first case of single port laparoscopic right hemicolectomy for advanced colon cancer. An abdominal 3 cm length incision was made via the umbilicus. A small wound retractor and a surgical glove were used as a single port. All soft tissue anterior to the superior mesenteric vein was completely removed and D3 lymph node dissection was achieved. The total operative time was 180 min with minimal blood loss (< 50 mL). The size of the tumor was 5 cm x 3 cm and its tumor stage was T3N0. Sixty-nine lymph nodes were harvested and none were positive. We believe that single port surgery for colon cancer is a feasible and safe procedure with surgical results comparable to conventional laparoscopic procedures.
