Detailed explanation-1: -Overall, one to three dilations are sufficient to relieve dysphagia in simple strictures. Only 25–35 % of patients require additional sessions, with a maximum of five dilations in more than 95 % of patients [4]. Complex strictures are usually longer (>2 cm), angulated, irregular, or have a severely narrowed diameter.
Detailed explanation-2: -Depending on the degree and cause of narrowing of your esophagus, it is common to require repeat dilations. This allows the dilation to be performed gradually and decreases the risk of complications. Once the stricture, or narrowed esophagus, is completely dilated, repeat dilations may not be required.
Detailed explanation-3: -Most of the effects of the sedation persist for 15-60 minutes, and you may not be able to recall the procedure afterwards. Your throat is usually anesthetized with a spray or liquid to minimize the gag reflex. The endoscope is then gently inserted into the upper esophagus and advanced through the upper digestive tract.
Detailed explanation-4: -The “rule of three” in dilation of esophageal strictures suggests that in a single session, no more than three bougie dilators of sequentially larger size should be passed once moderate or greater resistance is evident. (Dilators passed with no or mild resistance do not count toward this total.)
