Abstract:
Objective To assess the safety, effectiveness and predictive factors of endoscopic balloon dilatation for the treatment of esophageal stricture and esophageal achalasia in children. Methods 28 patients with esophageal stricture and esophageal achalasia treated by endoscopic balloon dilatation from January 2012 to November 2014 were included. All the patients were divided into two groups, 22 in group A (esophageal stricture) and 6 in group B (esophageal achalasia). All procedures were performed under tracheal intubation and intravenous anesthesia using the 3rd grade controlled radial expansion (CRE) balloon with gastroscope. Outcomes, including success, complications and recurrence data were recorded, and predictors for outcomes were analyzed. Results A total of EBD 57 sessions (1 to 5 per patient, 2.00 ± 1.15) were performed on 28 patients in this study. 22 patients were diagnosed with esophageal stricture (78.57%) and 6 with esophageal achalasia (21.43%). The median age was 25 months (range 0 ~ 150), and female/ male ratio was 12/16. EBD was successful in all the 28 cases. The total success rate was 100.00%. Complications occurred in 6 patients during the dilatation, and no complication in 22 patients. Completely remission of symptoms was seen in 82.14% cases (n = 23), relief in 14.28% (n = 4), non-response in 3.57% (n = 1), and recurrence in 3.57% (n = 1). The stricture diameter before EBD was (6.28 ± 1.77) mm (range 3.0 ~ 10.0 mm), and it was (10.85 ± 2.51) (range 6 ~ 15 mm) after the last EBD. The difference was significant (P < 0.01). There was no significant difference in success, effectiveness, complications and recurrence among the two groups (P > 0.05). The effectiveness of EBD was significantly associated with the diameter and number of strictures (P < 0.05), more complications were seen in the patients with multiple and/or smaller strictures (P < 0.05). In group A, the longer interval between surgery and the first EBD was related to more dilatation in the patients with anastomotic esophageal strictures (P < 0.05). The age and the interval between symptom onset and the first EBD were not the predicting factors for treatment in group B (P > 0.05). Conclusions The results of this study indicated that EBD under general anesthesia was an effective primary treatment in children with esophageal stricture and esophageal achalasia. The diameter and number of stricture were the most important predictive factors for successful clinical outcomes, while the interval between surgery and the first EBD was the most risk factor for EBD sessions in the patients with anastomotic esophageal strictures.
