Application Of Pelvic Floor Peritoneal Closure Reconstruction In Laparoscopic Resection Of Low Rectal Cancer

Background: Low rectal cancer is a difficult point in the treatment of colorectal cancer.At present,with the development of laparoscopic minimally invasive technology,laparoscopic rectal resection has become an important surgical treatment for colorectal cancer.Laparoscopic radical resection of low rectal cancer has less surgical trauma than traditional open surgery.However,it may still cause various surgical complications,including surgical site infection,perineal hernia,adhesive intestinal obstruction,etc.,increasing the pain of patients and prolonging the hospital stay.Objective: To evaluate whether pelvic peritoneal reconstruction(PPR)can reduce the incidence of complications in laparoscopic low rectal cancer surgery and the safety of using prickly suture to repair pelvic peritoneum.Methods: According to the inclusion and exclusion criteria,the clinical data of patients who received laparoscopic low rectal cancer radical surgery in Aden Abdulle Hospital in Somalia from January 2010 to December 2020 were collected.Patients were divided into experimental group(laparoscopic rectal resection combined with PPR)and control group(only laparoscopic rectal resection without PPR)according to whether they received PPR during operation.All patients received standard treatment before and after operation.Observation indicators:(1)Basic clinical characteristics of patients: age,sex,complications,etc;(2)Operation condition: operation time,bleeding volume,etc;(3)Postoperative pathological examination: tumor stage,number of lymph nodes cleared,etc.(4)Postoperative complications: surgical site infection,intestinal obstruction,perineal hernia,etc.SPSS17.0 statistical software was used for statistics.Results: A total of 402 patients receiving rectal cancer surgery in the Somali Aden Abdulle Hospital were included in this study,including 216 cases in the experimental group and 186 cases in the control group.There was no significant difference between the two groups in terms of surgical approach,incision margin,tumor size,postoperative T stage,postoperative N stage,number of positive lymph nodes,number of lymph nodes cleaned,perineal wound infection,perineal hernia,postoperative pneumonia,postoperative bleeding,presacral effusion,abdominal pelvic abscess,etc.There were significant differences between the two groups in terms of operation time,bleeding volume,incidence of anastomotic leakage and incidence of small intestinal obstruction.Conclusion: It is safe and reliable to perform pelvic peritoneum closure and reconstruction during laparoscopic rectal resection,which can reduce postoperative complications to a certain extent.
