Abstract Twenty-one patients with corrosive esophageal strictures underwent contrast-enhanced CT of the chest to determine (1) the esophageal wall thickness at the stricture site and (2) its correlation with number of sessions required for adequate dilation. Average esophageal wall thickness was defined as the mean thickness of all four walls at the site of the stricture, whereas the size of the thickest wall was taken as maximal esophageal wall thickness. Average esophageal wall thickness (8.52 +/- 0.61 mm; range, 5.4 to 13.5 mm) and maximal esophageal wall thickness (11.63 +/- 0.83 mm; range, 5.4 to 20 mm) were significantly higher in patients with corrosive esophageal strictures than normal esophageal wall thickness (2.70 +/- 0.04 mm, p < .01). These patients required a mean of 5.70 +/- 1.42 sessions for achieving adequate dilation. Age, sex, grade of dysphagia, and cause and site of the stricture did not influence the number of sessions required for adequate dilation. On multivariate analysis, maximal esophageal wall thickness (p < .01) but not average esophageal wall thickness or stricture length was independently associated with the number of sessions required for adequate dilation. Patients with maximal esophageal wall thickness of 9 mm or more required a significantly higher number of sessions for adequate dilation than did those with wall thickness of less than 9 mm (7.57 +/- 1.80 versus 1.42 +/- 0.27, p < .05).(ABSTRACT TRUNCATED AT 250 WORDS)
