Clinical study of laparoscopic resection of rectal cancer with three trocar

Objective To evaluate the treatment of the laparoscopic resection of rectal carcinoma with three trocars.Methods Seven hundred patients recruited according to the inclusion criteria were randomly divided into two groups.The laparoscopic group contains 345 patients who received laparoscopic radical resection,and the open group contains 355 patients who underwent open radical resection.The differences on the intraoperative and postoperative general conditions,pathological factors concerning with the operation,postoperative complications and the follow-up data 1-5 years after operation were compared between the two groups.Results Compared to the open group,the volume of bleeding was less in the laparoscopic group,the passage of flatus occurred earlier.Patients got off bed earlier in the laparoscopic group.But the average operation time was significantly longer.There was no difference for postoperative complications,the mean number of lymph nodes resected,length of lower resected margin to the tumor,the rate of relapse,metastasis,mortality in 1-5 year after operation between the two groups.Conclusions Laparoscopic radical resection of rectal carcinoma with three trocars is a feasible procedure with better short-term outcomes.
