Abstract：Objective To investigate the clinical effect of pelvic floor peritoneal reconstruction combined with transanal ileal tube placement during laparoscopic anterior resection of low rectal cancer.Methods A total of 84 patients with middle to low rectal cancer who underwent surgical treatment in our hospital from January 2022 to May 2024 were selected as the observation subjects.All of them were clinically diagnosed through colonoscopy and pathological examination.They were randomly divided into the control group and observation group,with 42 cases per group.Conventional surgery was performed in all patients,and those in the observation group were additionally treated with pelvic floor peritoneal reconstruction combined with transanal ileal tube placement for drainage.Results All enrolled patients successfully completed laparoscopic resection,without cases of conversion to open surgery or deaths during the operation.After postoperative pathological examination,rectal cancer was confirmed in all cases.Negative margin of the cutting edges on bilateral sides was confirmed by pathology.The incidence of postoperative anastomotic leakage in the observation group was significantly lower than the control group(P<0.05).All patients with postoperative anastomotic leakage were managed by comprehensive conservative treatments,such as parenteral nutrition,pelvic irrigation via drainage tube,and anti-infection,and all of them were cured after active treatments.Postoperative follow-up showed no occurrence of anastomotic stenosis,tumor recurrence,distant metastasis,or other conditions.The postoperative hospitalization time of the observation group was significantly shorter than the control group(P<0.05).No significant differences were found in the anal high-pressure zone,anal resting pressure,anal maximum contraction pressure between groups(P>0.05),which were all significantly reduced after 2 months of treatment,and significantly pronounced in the observation group than the control group(P<0.05).Conclusion During laparoscopic low rectal precancerous resection,the closure of the pelvic floor peritoneum and the placement of the anorectal obstruction catheter can reduce the possibility of contacting intestinal contents,achieve the goal of full decompression of the anastomosis,prevent postoperative anastomosis leakage,promote postoperative recovery,and further improve the anorectal function.
