“…Although the stent indwelling time of this study is relatively shorter than that of other studies that used plastic stents, 6,7 the leakage occlusion rate is similar to, or even higher than, that of other studies. 7,8,10 We decided to use a stent indwelling time of 2 weeks because, in our experience, the incidence of significant marginal ulcer increased after that. The PR-SEMS was designed to be fully covered for prevention of marginal ulcer, but that has proven to be ineffective.…”

“…Excellent symptom response has been sustained for over 8 months (no dysphagia). Patient outcomes after placement of selfexpanding metal stents (SEMS) and selfexpanding plastic stents (SEPS) for benign esophageal strictures are disappointing due to notable stent-related complications, including hyperplastic tissue ingrowth (SEMS) [1] and stent migration (SEPS) [2]. Novel self-expanding biodegradeable stents are an alternative and may benefit patients with benign esophageal strictures and achalasia, and have the potential to become primary therapy, replacing other stent types and balloon dilation [3,4].…”

“…Plastic stents have been evaluated in several trials, with disappointing results in terms of clinical success, with only 6%-30% long-term symptom improvement. 3,4 Complications were frequent and consisted mainly of migrations (22%-64.2%), chest pain (11%), bleeding (8%) and perforations (5.5%). 3 One death from massive bleeding was reported by Dua et al 3 Data concerning metal stents are sparse, with published studies including only small numbers of patients [6][7][8] or patients with particular lesions, such as benign hypopharyngeal strictures 6 or achalasia.…”

Background: Some esophageal strictures resist endoscopic treatments. There is a need for new treatments, such as specifically designed stents. Objective: Our study sought to compare the results achieved with a standard, fully covered metallic stent (FCMS) and those achieved using a stent designed specifically for benign strictures (BS-FCMS). Patients and methods: The study used a prospective, multicenter, controlled design, with patients recruited from tertiary referral centers. Patients with refractory esophageal strictures were included. Standard FCMS were used in group 1 (N ¼ 24), and BS-FCMS were used in group 2 (N ¼ 17). Patients were followed for 24 months after stent removal. The main outcomes measured were stricture resolution rate, 24 months' recurrence rate and stent-related morbidity. Results: Early stent migrations occurred in one (4.1%) patient from group 1 and five (29.4%) from group 2 (p < 0.05). During esophageal stenting, complications occurred in six patients (25%) in group 1 and six patients (35.3%) in group 2 (p ¼ 0.47), respectively. Fifty percent of complications were attributed to migration. There was no procedure-related morbidity associated with the extraction of the stent. The stricture resolution rate was, respectively, 95.2% in group 1 and 87.5% in group 2 (the difference between the two groups is not significant). During follow-up, stricture recurrence occurred in 15/19 patients (group 1, 79%) and 7/8 patients (group 2, 87.5%; p ¼ 1.0). The median time to recurrence of esophageal stricture was 1.7 months (group 1, 0.6-12 months) and 1 month (group 2, 0.1-6 months). Study limitations include its nonrandomized design. Conclusion: The stricture resolution rate was high at the end of the stenting period for both types of stents without any statistical difference between the two groups, but the long-term results were disappointing, with stricture recurring frequently and rapidly in both groups.
