Abstract:
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 = 24), and BS‐FCMS were used in group 2 ( N = 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 = 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 = 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.
