Abstract

Background Factors associated with successful endoscopic therapy with temporary stents for esophageal leaks, fistulae, and perforations (L/F/P) are not well known. Objectives To evaluate the safety, efficacy, and outcomes of esophageal stenting in these patients and identify factors associated with successful closure. Design Retrospective. Setting Academic tertiary referral center. Patients All patients with attempted stent placement for esophageal L/F/P between January 2003 and May 2012. Intervention Esophageal stent placement and removal. Main Outcome Measurements Factors predictive of therapeutic success defined as complete closure after index stent removal (primary closure) or after further endoscopic stenting (secondary closure). Results Sixty-seven patients with 132 attempted stents for esophageal L/F/P were considered; 13 patients were excluded. Among the remaining 54 patients, 117 stents were placed for leaks (29 patients; 64 stents), fistulae (15 patients; 36 stents), and perforations (10 patients; 17 stents). Procedural technical success was achieved in all patients (100%). Primary closure was successful in 40 patients (74%) and secondary closure in an additional 5 (83% overall). On short-term (<3 months) follow-up, 27 patients (50%) were asymptomatic, whereas 22 (41%) had technical adverse events, including stent migration in 15 patients (28%). Factors associated with successful primary closure include a shorter time between diagnosis of esophageal L/F/P and initial stent insertion (9.03 vs 22.54 days; P =.003), and a smaller luminal opening size (P =.002). Limitations Retrospective, single-center study. Conclusions Temporary stents are safe and effective in treating esophageal L/F/P. Defect opening size and time from diagnosis to stent placement appear to be candidate predictors for successful closure.
