Abstract
In this paper we report a technique for laparoscopic lymph node (LN) dissection for descending and proximal sigmoid colon cancer with the preservation of the superior rectal artery (SRA) to maintain the blood supply to the distal sigmoid colon. Five (5) cases were included from November 2004 to March 2005. For D3 LN dissection, the root of inferior mesenteric artery was exposed with ultrasonic cutting and coagulating surgical device to avoid bleeding. The arterial wall was then exposed with a spatula-type electric cautery down to the left colic artery (LCA). The LCA was then clipped and cut while preserving the SRA. The inferior mesenteric vein was divided at the caudal side of the LCA and prior to joining to the splenic vein. All cases underwent a LN dissection laparoscopically. There were no cases of complications originating from the LN dissection. Although long-term outcomes should be investigated, our results indicate that this is a safe, applicable method.
