To investigate the technique and effect that reduced tension of anastomotic stoma for laparoscopic radical resection of rectal cancer.

Summary and analysis the clinical data of 243 patients that were carried out surgery of Dixon with laparoscopic radical resection of rectal cancer. All cases disconnect the inferior mesenteric artery in roots and only staged the edge vascular arcades of the colon. The 86 patients of the descending colon were freed to the splenic of colon, the incidence rate was 35.4%. The 57 patients were sutured for reduceing the tension of anastomotic stoma in before and below of the anterior superior iliac spine. The incidence rate was 23.4%.

All cases of anastomotic were without tension.The operation time was 85-145 min, average 135min. The amount of bleeding was 5-100 ml, the average was 10 ml. The specimens that was checked the number of lymph nodes was 9-17. The anastomotic leakage occurred in 2 cases, The incidence rate was 0.8%.

It is necessary to ensure that anastomotic completely without tension in laparoscopic radical resection with Dixon of rectal cancer. when the length of colon is not enough, the colon should free to the splenic flexure .It can reduce the tension of anastomotic stoma that sutured the colon to the before and below of the anterior superior iliac spine. This is can reduce the incidence of the anastomotic eakage.
