Abstract

BACKGROUND & AIMS: Conservative treatment (intensive care, a combination of antimicrobial agents, and nutritional support, with or without drainage of the infected fluid) has recently been shown to be effective for patients with infected pancreatic necrosis (IPN), but the data from individual studies are not robust enough to recommend it as the standard of care. We performed a systematic review and meta-analysis of studies related to primary conservative management for IPN. METHODS: We performed a literature search of MEDLINE/PUBMED from January 1990 to March 2012 for studies of priori protocols for primary conservative treatment, without necrosectomy, for consecutive patients with IPN. We analyzed data from 8 studies, comprising 324 patients with IPN who received primary conservative management. We then analyzed an additional 4 studies (comprising 157 patients) that reported the efficacy of percutaneous drainage in non-consecutive patients with IPN. Outcome measures were the success of conservative management strategy, need for necrosectomy, and mortality. RESULTS: There was significant heterogeneity in results among the studies. Based on a random effects model, conservative management was successful for 64% of patients (95% confidence interval [CI], 51%-78%); mortality was 12% (95% CI, 6%-18%), and 26% of patients required necrosectomy or additional surgery for complications (95% CI, 15%-37%). A separate analysis of 4 studies that reported outcomes of non-consecutive patients with IPN, following percutaneous drainage, had comparable results-50% had successful outcomes (95% CI, 43%-58%), mortality was 18% (95% CI, 6%-30%), and 38% of patients required surgery (95% CI, 20%-56%). CONCLUSION: Conservative management without necrosectomy is a successful approach for 64% of patients with IPN. This approach has low mortality and prevents surgical necrosectomy.
