Abstract：Objective:To observe the application effect of laparoscopic transanal total mesorectal excision (Lap-taTME) in low rectal cancer patients undergoing anal sphincter preservation surgery.Method:Fifty patients with low rectal cancer who intended to undergo anal preservation surgery were selected from Dehua County Hospital from January 2022 to February 2024.According to the method of random number table,they were divided into control group and study group,25 cases in each group.The control group was given total mesorectal excision (TME) and the study group was given Lap-TaTME.Perioperative indexes,recovery condition,anal function 3 months after surgery,surgical conversion rate,and short-term poor prognosis of tumors were compared between the two groups.Result:The intraoperative blood loss volume in the study group was less than that in the control group,and the operative time was longer than that in the control group,the differences were statistically significant (P<0.05).Incision healing time and hospital stay in the study group were shorter than those in the control group,and postoperative anal exhaust time and getting out of bed activity time were significantly earlier than those in the control group,the differences were statistically significant (P<0.05).Three months after surgery,the Wexner score of the study group was lower than that of the control group,and the difference was statistically significant (P<0.05).The conversion rate of surgery in the study group was 8.00％ (2/25),which was lower than 36.00％ (9/25) in the control group,and the difference was statistically significant (P<0.05).There was no significant difference in the incidence of short-term adverse prognosis between the two groups (P>0.05).Conclusion:Lap-TaTME can reduce the amount of surgical bleeding in patients with low rectal cancer,accelerate postoperative recovery,optimize anal function,and reduce the rate of surgical conversion.
