Abstract
Objective To investigate therapeutic effect of endoscope-guided bougie dilatation on children with benign esophageal stricture. Methods Data of 71 patients with benign esophageal stricture were retrospective analyzed.Patients were divided into group A (reflux stricture), B (congenital esophageal atresia stricture) and C (caustic injuries stricture), based on different causes. The expansion effectiveness and factors of the three groups were analyzed. Results A total of 885 expansions were performed on 71 patients with the total efficacy rate 94.37%(67/71). No statistic differences were shown in expansion effectiveness among the 3 groups; group C(14.9 times/case, P<0.05)showed more expansion frequencies than group A (9.1 times/case, P<0.05)and group B(10.7 times/case, P<0.05), more complications than group A(1.22% VS 0, P<0.05) and group B(1.22% VS 0.31%, P<0.05). Conclusion Endoscope-guided bougie dilatation is safe and effective for childrens′ benign esophageal stricture. Caustic injuries, refractory benign esophageal stricture, need more expansions and may be accompanied with more complications. Key words: Children benign esophageal stricture; Endoscope-guided dilatation; Effectiveness; Risk factor
