ABSTRACT: Background
The optimal target of endoscopic dilation of postsurgical esophageal strictures is unknown. Our aim was to compare the dilation-free period of patients who underwent dilation up to 16 mm with patients who were dilated up to 17 or 18 mm.Methods
We retrospectively analyzed adult patients who received bougie/balloon dilation for a benign anastomotic stricture after esophagectomy. An anastomotic stricture was defined as dysphagia in combination with a luminal diameter of ?13 mm at endoscopy. We analyzed the dilation-free period using Kaplan-Meier and multivariable Cox regression analysis.Results
Eighty-eight patients were dilated up to a maximum diameter of 16 mm and 91 patients to a diameter >16 mm. The stricture recurrence rate was 79.5 % in the 16 mm group and 68.1 % in the >16 mm group (p = 0.083). The overall dilation-free period had a median of 41.5 (range 8-3233) days and 92 (range 17-1745) days, respectively (p < 0.001). For patients who developed a stricture recurrence, the median dilation-free period was 28 (range 8-487) days and 63 (range 17-1013) days, respectively (p = 0.001). Cox regression analysis showed a reduced risk of stricture recurrence for patients who were dilated up to >16 mm: crude hazard ratio (HR) 0.57 (95 % confidence interval (CI) 0.41-0.81) and adjusted HR 0.48 (95 % CI 0.33-0.70).Conclusions
Endoscopic dilation over 16 mm resulted in a significant prolongation of the dilation-free period in comparison with dilation up to 16 mm in patients with benign anastomotic strictures after esophagectomy.
