Investigate Avoid Ureter Injured From Anatomical Factors In The Laparoscpic Radical Resection For Colorectal Cancer--Separate And Expose Toldt's Fascia

Objective To investigate how to decrease the risk of ureteral injured in the laparoscopic radical resection for colorectal cancer from the anatomical level.Methods Video information of 80 cases of laparoscopic radical resection for colorectal cancer from December 2006 to December 2008 were analyzed retrospectively , Observation of the main surgical approachs,and the relationship between ureter and Toldt's fascia,Investigate the method avoid ureter injured in the laparoscopic radical resection for colorectal cancer.Results 80 cases of laparoscopic radical resection for colorectal cancer were successfully completed surgery. The main use of Mesocolon approach and Lateral peritoneal approach,too much separation ureter and breakthrough Toldt's fascia are easy to injure the ureter both in two of surgical approach(7 vs.5cases, p=0.75).Conclusion Both two surgical approachs have their own characteristic, familiar with the ureter's dissection relations, and accurate search Toldt's fascia at intraoperative is the key to avoiding injure ureter.
