Endo-sponge in management of anastomotic colorectal leaks: a systematic review and meta-analysis.

ABSTRACT: Background and study aims Following colorectal surgery, anastomotic dehiscence and leak formation has an incidence of 2 % to 7 %. Endo-SPONGE has been applied in the management of anastomatic leaks (ALs) after colorectal surgery. This is the first systematic review and meta analysis to evaluate the efficacy and safety of Endo-SPONGE in the management of colorectal ALs. Patients and methods The primary outcomes assessed were the technical and clinical success of Endo-SPONGE placement in colorectal ALs. The secondary outcomes assessed were the overall adverse events (AEs) and the AE subtypes. Pooled estimates were calculated using random-effects models with 95 % confidence interval (C. I.). The statistical analysis was done using STATA v16.1 software (StataCorp, LLC College Station, Texas, United States). Results The analysis included 17 independent cohort studies with a total of 384 patients. The rate of technical success was 99.86 % (95 % CI: 99.2 %, 100 %; P = 0.00; I ² = 70.69 %) and the calculated pooled rate of clinical success was 84.99 % (95 % CI: 77.4 %, 91.41 %; P = 0.00; I ² = 68.02 %). The calculated pooled rate of adverse events was 7.6 % (95 % CI: 3.99 %, 12.21 %; P = 0.03; I ² = 42.5 %) with recurrent abscess formation and bleeding being the most common AEs. Moderate to substantial heterogeneity was noted in our meta-analysis. Conclusions Endoscopic vacuum therapy appears to be a minimally invasive, safe, and effective treatment modality for patients with a significant colorectal leak without any generalized peritonitis with high clinical and technical success rates and a low rate of adverse events. Further prospective or randomized controlled trials are needed to validate our findings.

Project description:Objective: To evaluate the safety and efficacy of endoscopic procedures for ureteroenteric anastomotic strictures (UESs) after radical cystectomy and urinary diversion. Methods: We performed a meta-analysis of relevant articles through March 2020 using PubMed, Embase, and Cochrane Central Register to assess the efficacy of endoscopic procedures in UES according to the PRISMA and PICOS criteria. The main endpoints were success rate and complications, and we also compared the efficacy of different methods and stricture length and side in UES. Cochrane Collaboration's Revman version 5.3 and Stata version 15.1 software were used for statistical analysis. Results: A total of 18 retrospective studies with 697 patients were included. The median follow-up ranges from 12 to 62.5 months. Patients treated with endoscopic procedures had an overall success rate of 46%. The pooled rate of Clavien-Dindo ≥ 3 complications was 3.8% among included studies. Laser vaporization and stent insertion (48 and 47%) had a relatively high success rate than balloon dilatation (35%). In subgroup analysis, the success rate of endoscopic procedures for ≤ 1-cm strictures was significantly higher than that for >1-cm ones [odds ratio (OR), 8.65; 95% confidence interval (CI), 3.53-21.21; P < 0.00001]. In addition, the success rate in cases with strictures of the right side was relatively higher than that in cases with strictures of the left side (OR, 1.72; 95% CI, 1.05-2.81; P = 0.03). Conclusion: Our pooled studies showed that endoscopic operation is feasible and associated with a moderate success rate along with a relatively low incidence of perioperative complications in the treatment of UES, especially with length ≤ 1 cm and right side. Although there is still no consensus on endoscopic technique for UES regarding balloon dilatation, stent insertion, and laser vaporization, we believe that endoscopic management is a safety and available approach for UES with close follow-up.
