Abstract: Objective To observe the clinical effect of laparoscopic total mesorectal excision (LTME) with pelvic automatic nerve preservation (PANP) on patients with rectal cancer.Methods A total of 82 patients with rectal cancer were selected from February 2012 to June 2015 in Luoding People’s Hospital.Of them,41 cases received open total mesorectal excision and PANP (OTME+PANP group),and the other 41 cases received LTME and PANP (LTME+PANP group).The operation condition,complication incidence,and survival rate within one year of each group were observed.Results The operation time,bleeding volume,recovery time of gastrointestinal function,time of leaving bed,and hospitalization time of the LTME+PANP group was significantly better than those of the OTME+PANP group (P<0.05); the incidence rate of complications of the LTME+PANP group was significantly lower than that of the OTME+PANP group (7.32% vs.21.95%,P<0.05); the recurrence rate (0%) and the survival rate (100%) within one year of the LTME+PANP group were not statistically different from those of the OTME+PANP group (2.44% and 100%) (P<0.05).Conclusion The combination of LTME and PANP has a better treatment effect for patients with rectal cancer,resulting in decreased postoperative complication incidence and faster recovery of gastrointestinal function,thus the surgery is worthy of clinical application.
