Impact of ileostomy on postoperative wound complications in patients after laparoscopic rectal cancer surgery: A meta-analysis.

Abstract

To prevent anastomotic leakage and other postoperative complications after laparoscopic rectal cancer surgery, a protective ileostomy is often used. However, the necessity of performing ileostomy after laparoscopic rectal cancer remains controversial. The aim of this meta-analysis was to assess the benefit of ileostomy on wound infection after laparoscopic rectal cancer. The Cochrane Library, EMBASE, Web of Science, and PubMed were used to retrieve all related documents up to September 2023. Completion of the trial literature was submitted once the eligibility and exclusion criteria were met and the literature quality assessment was evaluated. This study compared the post-operative post-operative complications of an ileostomy with that of non-ileostomy in a laparoscope. We used Reman 5.3 to analyse meta-data. Controlled studies were evaluated with ROBINS-I. The meta-analyses included 525 studies, and 5 publications were chosen to statistically analyse the data according to the classification criteria. There was no statistically significant difference in the rate of postoperative wound infections among ostomate and nonostomate (odds ratio [OR], 1.79; 95% confidence interval [CI], 0.66, 4.84; p = 0.25). In 5 trials, the incidence of anastomotic leak was increased after surgery in nonostomate patients (OR, 0.26; 95% CI, 0.12, 0.57; p = 0.0009). Two studies reported no significant difference in the length of operation time when nonstomal compared to stomal operations in patients with rectal cancer (mean difference, 0.87; 95% CI, -2.99, 4.74; p = 0.66). No significant difference was found in the rate of wound infection and operation time after operation among the two groups, but the incidence of anastomosis leak increased after operation. Protective ileostomy after laparoscopic rectal cancer was effective in reducing the risk of anastomotic leakage in patients, and we found no additional risk of infection. We cautiously conclude that protective ileostomy is active and necessary for patients with a high risk of anastomotic leakage after surgery, which needs to be further confirmed by high-quality studies with larger samples.
