Factors influencing the occurrence of parastomal hernia after preventive ileostomy for colorectal cancer / 中国医师杂志

ABSTRACT

Objective:To explore the risk factors related to the formation of parastomal hernia (PSH) in patients with colorectal cancer after preventive ileostomy, provide Evidence-based medicine basis for prevention and treatment, and reduce the incidence of incision hernia (SSIH) at the stoma.Methods:The clinical data of 214 patients who underwent laparoscopic radical resection of colorectal cancer combined with preventive loop ileostomy in the General Surgery Department of the Linyi People′s Hospital from January 2019 to May 2021 were retrospectively analyzed. The incidence of PSH was statistically analyzed, and the risk factors of PSH were analyzed by binary logistic regression.Results:There were 177 cases of PSH in 214 patients, with an incidence rate of 82.71%. There were 5 cases of SSIH (2.34%). The results of single factor analysis showed that there were significant differences in body mass index (BMI), postoperative diversion time and the proportion of stoma through rectus abdominis muscle between the PSH group and the non PSH group (all P<0.05); The results of binary logistic regression analysis showed that BMI, postoperative diversion time, rectus abdominis muscle stoma, incision infection and liquefaction were important influencing factors for the formation of PSH after preventive loop ileostomy for colorectal cancer (all P<0.05). Conclusions:BMI, postoperative diversion time, rectus abdominis muscle stoma, incision infection and liquefaction are important influencing factors for the formation of PSH after preventive ileostomy. Intervention measures can be targeted to reduce the incidence of SSIH by reducing the risk of PSH.
