BACKGROUND: Placement of self-expanding metal stents (SEMS) or plastic stents (SEPS) has emerged as a minimally invasive treatment option for benign oesophageal ruptures and leaks; however, it is not clear which stent type should be preferred. AIM: To assess clinical effectiveness and safety of treating benign oesophageal ruptures and anastomotic leaks with temporary placement of a stent with special emphasis on different stent designs. METHODS: A pooled analysis was performed after searching PubMed and EMBASE databases for studies regarding placement of fully covered and partially covered SEMS (FSEMS and PSEMS) and SEPS for this indication. Data were pooled and evaluated for clinical outcome, complications and survival. RESULTS: Twenty-five studies, including 267 patients with complete follow-up on outcome, were identified. Clinical success was achieved in 85% of patients and was not different between stent types (SEPS 84%, FSEMS 85% and PSEMS 86%, P = 0.97). Time of stent placement was longest for SEPS (8 weeks) followed by FSEMS and PSEMS (both 6 weeks). In total, 65 (34%) patients had a stent-related complication. Stent migration occurred more often with SEPS [n = 47 (31%)] and FSEMS [n = 7 (26%)] than with PSEMS [n = 2 (12%), P ≤ 0.001], whereas there was no significant difference in tissue in- and overgrowth between PSEMS [12% vs. 7% (FSEMS) and 3% (SEPS), P = 0.68]. CONCLUSIONS: Although there is a lack of randomised controlled trials, it seems that covered stent placement for a period of 6-8 weeks is safe and effective for benign oesophageal ruptures and anastomotic leaks to heal. As efficacy between different stent types is not significantly different, stent choice should depend on expected risk of stent migration (self-expanding plastic stents and fully covered self-expanding metal stents) and, to a minor degree, on expected risk of tissue in- or overgrowth (partially covered self-expanding metal stents).
