ABSTRACT

Objective To evaluate the curative effect of trans-anal surgery vs.conventional laparoscopic surgery in treating sigmoid and high-rectum tumor.Methods From Jan 2014 to Mar 2017,100 patients in Beijing Friendship Hospital participated in this clinical study.45 patients underwent transanal surgery and 55 patients underwent conventional laparoscopic surgery.Results No significant difference was found between trans-anal surgery group and the traditional laparoscopic group in terms of operation time,blood loss,the use of analgesic drugs and the radical evaluation of tumor.While the postoperative pain scores in trans-anal surgery group (2.0 ± 1.0 vs.2.6 ± 1.0,t =2.9,P =0.005) were lower than those in the conventional group.The follow-up data showed one case of local tumor recurrence and one case of multiple peritoneal metastasis in the trans-anal surgery group,compared to two cases of liver metastasis and one case dying of pneumonia in the conventional laparoscopic group.The remaining cases were of no local recurrence,nor distant metastases or any critical complications.Conclusions Trans-anal surgery in the treatment of sigmoid and high-rectum tumor is safe,reliable and having the same clinical efficacy with conventional laparoscopic surgery.
