Abstract

Background: Surgical strategies for acute perforated diverticulitis with generalised peritonitis remain controversial. This study aimed to meta-analyse trials comparing primary resection and anastomosis (PRA) to Hartmann's procedure (HP) for Hinchey III/IV diverticulitis.

Methods: A systematic literature search was conducted to identify observational studies and randomised control trials (RCTs) of patients with Hinchey III/IV diverticulitis undergoing sigmoidectomy that compared PRA to HP. The methodological quality of the included studies was assessed systematically (Newcastle-Ottawa, Jadad and Cochrane risk of bias scores) and a meta-analysis was performed.

Results: After removal of duplicates, 12 studies including 4 RCTs were identified. The analysis included 918 patients, of whom 367 (39.98%) underwent PRA. Both the initial stoma rate (risk ratio [RR] persistent stoma 0.43, 95% confidence interval [CI] 0.26, 0.71, p = 0.001; I2 = 99%, p < 0.0001) and the rate of permanent stoma after combining the first (emergency surgery) and second (stoma reversal) procedures were lower in the PRA group. There was no difference in in 30-day mortality; however, PRA resulted in a reduction in overall mortality as well as major complications after the initial operation (RR 0.67, 95% CI 0.46, 0.97, p = 0.03; I2 = 22%, p = 0.26), stoma reversal (RR 0.48, 95% CI 0.26, 0.92, p = 0.03; I2 = 0%, p = 0.58) and when combining both procedures (RR 0.67, 95% CI 0.51, 0.88, p = 0.005; I2 = 0%, heterogeneity p = 0.58). A subgroup analysis of stoma reversal rates using data from only RCTs were consistent (RR permanent stoma, 0.33, 95% CI 0.13, 0.85, p = 0.02; I2 = 77%, p = 0.004) with the findings of the overall analysis.

Conclusions: This meta-analysis demonstrates that PRA used in the management of haemodynamically stable patients with Hinchey grade III/IV diverticulitis leads to a lower overall persistent stoma rate, with reduced morbidity compared with the traditional management.
