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

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.

The efficacy of ileostomy after laparoscopic rectal cancer surgery: a meta-analysis

Background

Protective ileostomy is always applied to avoid clinically significant anastomotic leakage and other postoperative complications for patients receiving laparoscopic rectal cancer surgery. However, whether it is necessary to perform the ileostomy is still controversial. This meta-analysis aims to analyze the efficacy of ileostomy on laparoscopic rectal cancer surgery.

Methods

Cochrane Library, EMBASE, Web of Science, and PubMed were applied for systematic search of all relevant literature, updated to May 07, 2021. Studies compared patients with and without ileostomy for laparoscopic rectal cancer surgery. We applied Review Manager software to perform this meta-analysis. The quality of the non-randomized controlled trials was assessed using the Newcastle-Ottawa scale (NOS), and the randomized studies were assessed using the Jadad scale.

Results

We collected a total of 1203 references, and seven studies were included using the research methods. The clinically significant anastomotic leakage rate was significantly lower in ileostomy group (27/567, 4.76%) than that in non-ileostomy group (54/525, 10.29%) (RR = 0.47, 95% CI 0.30–0.73, P for overall effect = 0.0009, P for heterogeneity = 0.18, I² = 32%). However, the postoperative hospital stay, reoperation, wound infection, and operation time showed no significant difference between the ileostomy and non-ileostomy groups.

Conclusion

The results demonstrated that protective ileostomy could decrease the clinically significant anastomotic leakage rate for patients undergoing laparoscopic rectal cancer surgery. However, ileostomy has no effect on postoperative hospital stay, reoperation, wound infection, and operation time.
