ABSTRACT
Objective:To observe short-term effects of laparoscopic total mesorectal excision (LTME)combined with intersphincteric resection (ISR) and open abdominal ISR in treatment of low rectal cancer.Methods:74 patients with low rectal cancer from July 2012-December 2014 were analyzed retrospectively.Among them,38 cases underwent laparoscopic TME combined with ISR and another 36 patients underwent open ISR.Short-term prognosis of two groups were analyzed.Results:Operation time of (LTME+ISR) group was longer than that of open ISR group(P＜0.05);Intraoperative blood loss of (LTME+ISR) group was lower than that of open ISR group(P＜0.05);Difference of retrieved lymph nodes number and prophylactic colostomy number of two groups were not statistically significant(P＞0.05).Postoperative anus start exhaust time,start eating time and hospitalization time of (LTME+ISR) group were shorter than that of open ISR group (P＜0.05).Postoperative complication rate of (LTME+ISR) group was 13.16％,lower than that of open ISR group 33.33％(P＜0.05).Local recurrence rate and distant metastasis rate of (LTME+ISR) group were lower than that of open ISR group,2 year survival rate was higher than that of open ISR group,but the difference was not statistically significant (P＞0.05).Conlusion:LTME combined with ISR compared with open ISR,the operation time is longer.However,the amount of intraoperative bleeding is less,postoperative recovery is faster and less complications.The prognosis of the two surgical methods was similar in the 2 years.
