Abstract
AIM: The aim of this meta-analysis was to comparatively evaluate the outcomes of primary anastomosis (PRA) and nonrestorative resection (NRR) as emergency surgery and ostomy reversal in patients with perforated diverticulitis and peritonitis.
METHODS: PubMed, MEDLINE via Ovid, Embase, CINAHL, Cochrane Library and Web of Science databases were systematically searched. Postoperative morbidity following emergency resection was the primary end-point. Quality assessment of the included studies was performed using the Cochrane Quality Assessment Tool including recruitment bias and crossover with intention-to-treat analysis. The Haenszel-Mantel method with odds ratios (OR, 95% CI) and the inverse variance method with mean difference (MD, 95% CI) as effect measures were utilized for dichotomous and continuous outcomes, respectively.
RESULTS: Four randomized controlled trials totaling 382 patients (180 PRA vs 204 NRR) were included. Morbidity rates following emergency resection did not differ (OR = 0.99, 95% CI 0.65, 1.51; P = 0.95; number needed to treat/harm (NNT) 96). Organ/space surgical site infection rates were 3.3% in PRA vs 11.3% in NRR (OR = 0.29, 95% CI 0.12, 0.74; P = 0.009; NNT = 13). Postoperative morbidity rates following ostomy reversal were significantly lower in PRA (OR = 0.31, 95% CI 0.15, 0.64; P = 0.001; NNT = 7). Pooled ostomy non-reversal rates were 16% in PRA vs 35.5% in NRR (OR = 0.37, 95% CI 0.22, 0.62; P = 0.0001; NNT = 6) with high heterogeneity (I
CONCLUSION: This meta-analysis found that PRA was associated with better short- and long-term outcomes at the cost of significantly longer operating time at emergency surgery.
