Abstract
BACKGROUND AND AIMS: The management of refractory benign esophageal strictures (RBESs) is challenging. Stent placement has been proposed as a possible rescue strategy. We performed a systematic review and meta-analysis to examine the efficacy of this strategy in the long-term resolution of dysphagia. METHODS: PubMed, SCOPUS, and Google Scholar were searched (up to January 2015). Studies recruiting adults with RBES treated with stent placement were eligible. The success, adverse event, and migration rates were pooled by means of a random-effect model to obtain odds with a 95 % confidence interval (CI). RESULTS: Eighteen studies (444 patients) were eligible for inclusion. The pooled clinical success rate was 40.5 % (95 %CI 31.5 % - 49.5 %), yielding odds of 0.68 (95 %CI 0.46 - 0.98) with high heterogeneity (I(2) = 65.0 %). The meta-regression analysis showed stricture etiology as the only influencing factor. Treatment with self-expanding plastic (SEPSs) and metal stents (SEMSs) did not result in significantly higher success rates than treatment with biodegradable stents (BDSs) (46.2 % vs. 40.1 % vs. 32.9 %, respectively). The migration rate was 28.6 % (95 %CI 21.9 % - 37.1 %), yielding odds of 0.40 (95 %CI 0.28 - 0.59), with migration rates for SEPSs and SEMSs reported as being not significantly higher than BDSs (33.3 % vs. 31.5 % vs. 15.3 %, respectively). The adverse event rate was 20.6 % (95 %CI 15.3 % - 28.1 %), yielding odds of 0.26 (95 %CI 0.18 - 0.39) with no significant difference between stent types (19.4 % vs. 21.9 % vs. 21.9 %, respectively). CONCLUSIONS: Stent placement in patients with RBES is effective in about 40 % of cases. Further studies should investigate whether the clinical success rate varies according to the stricture etiology.(PROSPERO registration number: CRD42015019017.). © Georg Thieme Verlag KG Stuttgart · New York.
