Abstract:Objective To compare the efficacy of endoscopic bougie/balloon dilation (EBD), endoscopic radial incision (ERI), and ERI combined with esophageal stent placement (ESP) for the treatment of benign esophageal stenosis, and evaluate the feasibility and safety of ERI combined with ESP for the treatment of benign esophageal stenosis.Methods 48 Patients with benign esophageal stenosis from January 2019 to January 2023 were recruited, and divided into EBD group (n = 24), ERI group (n = 17) and ERI + ESP group (n = 7). The differences in operating success, restenosis and complications among the three groups were compared.Results The number of previous endoscopic treatment in ERI + ESP group was more than that in EBD group and ERI group, and the differences were statistically significant (P < 0.05). Technical success was achieved in 23 cases and clinical remission in 23 cases in EBD group, technical success in 16 cases and clinical remission in 15 cases in ERI group, technical success in 7 cases and clinical remission in 7 cases in ERI + ESP group. There was no significant difference in technical success rate and clinical remission rate among the three groups (P > 0.05). After 3 months of follow-up, there were 15, 9 and 1 cases of esophageal restenosis in the EBD group, ERI group and ERI + ESP group, respectively. There was no significant difference in the rate of esophageal restenosis among the 3 groups (P > 0.05). After 6 months of follow-up, there were 20 cases of esophageal restenosis in the EBD group, 13 cases in the ERI group and 1 case in the ERI + ESP group. The rate of esophageal restenosis in the ERI + ESP group was significantly lower than that in the EBD group and the ERI group (P < 0.05). However, there was no statistically significant difference in the esophageal restenosis rate between the EBD group and the ERI group (P > 0.05). The time to the first postoperative restenosis was 74.00 (48.75, 159.00) days in the EBD group, 84.00 (54.50, 195.00) days in the ERI group, and 250.00 (206.00, 289.00) days in the ERI + ESP group. The time to the first postoperative restenosis was longer in the ERI + ESP group than that in the EBD and ERI groups. The differences were statistically significant (P < 0.05), but there was no significant difference in restenosis time between EBD group and ERI group (P > 0.05). There were 5, 5 and 3 cases of complications in the EBD group, ERI group and ERI + ESP group, respectively, and there was no significant difference in the incidence of complications among the three groups (P > 0.05).Conclusion ERI+ESP is comparable to EBD and ERI in terms of technical success and short-term clinical remission rate for the treatment of benign esophageal stenosis, and is superior to EBD and ERI in terms of long-term restenosis rate and restenosis time, with no influence on the occurrence of complications.
