Abstract:Objective To investigate the safety and the clinical effects of endoscopic radial incision combined with local injection of triamcinolone acetonide (ERITA) for benign esophageal strictures.Methods Medical records for 54 patients with benign esophageal stricture in postoperative esophageal cancer from January 2018 to October 2021 were retrospectively analyzed. According to different surgical methods, the patients were divided into ERITA group (n = 19) and endoscopic bougienage dilation combined with local injection of triamcinolone (EBDTA) group (n = 35). Comparing treatment outcomes between the two groups, and the recurrence and complications of stenosis after treatment were evaluated.Results All the 54 patients successfully completed ERITA or EBDTA. The proportion of patients with refractory esophageal stenosis was higher in ERITA group. The time of operation for the ERITA group was longer than that of the EBDTA group [(45.5 ± 12.7) and (20.4 ± 8.6) min, P = 0.032]. The total adverse event rate was no significant difference between the two groups (P = 0.527). After six month of follow-up, the ERITA group was significantly longer than EBDTA group in maintaining the recurrence time of stenosis after operation (159.0 and 80.5 d, P = 0.037), and the efficacy of ERITA in the treatment of refractory esophageal stenosis was significantly better than that of EBDTA group.Conclusion ERITA is effective and safe in patients with benign esophageal strictures, and it shows promising results for the prevention of stricture recurrence, we believe that it is a promising method for refractory benign esophageal strictures in the future。
