Background and Aims This retrospective study was aimed at assessing the efficacy of endoscopic dilation for esophageal anastomotic strictures, and to compare response between caustic anastomotic strictures (CAS) and non-caustic anastomotic strictures (NCAS). Materials and Methods Patients with anastomotic strictures (enrolled during January 1996–December 2015) were analyzed. Short- and long-term outcomes of dilation, in terms of clinical success, refractory, and recurrent strictures were compared between NCAS and CAS. Patients with refractory and recurrent strictures were managed with adjunctive therapy including intralesional steroids. Factors predicting refractoriness at start of dilation and reasons for more than ten lifetime dilations were also evaluated. Results Of the 142 patients, 124 (mean age—44.02; males—74) underwent dilation. Clinical success was achieved in 113 (91.3%) patients requiring a median [Interquartile range (IQR)] of 4 (2–10) sessions. The number of dilations to achieve clinical success, refractory strictures, and recurrent strictures, and the use of adjunctive therapy were significantly higher for CAS than for NCAS. Intralesional steroid use decreased periodic dilation index (PDI) significantly in CAS. Caustic etiology and starting dilation diameter of < 10 mm were found to be predictors of refractoriness, with the former alone being an inde- pendent predictor of more than ten lifetime dilations.
