Abstract

Background: Benign gastroesophageal anastomotic strictures are common and often refractory to treatment. Various endoscopic dilation techniques have been reported, but none of these methods has been proven to be superior. Objective: Comparison of the efficacy and safety of dilation of previously untreated anastomotic strictures by using electrocautery incision (EI) and Savary bougienage (SB). Design: Randomized, prospective study Setting: Multicenter study Patients: Sixty-two patients with an anastomotic stricture after esophagogastrostomy and dysphagia Atkinson grades II to IV were included. Interventions: Patients were treated with El or SB. Main Outcome Measurements: Objective and subjective results were compared with baseline and 1, 3, and 6 months after the first treatment. Complications of both treatments were noted. Primary endpoints after 6 months were the mean number of dilation sessions and success rate (percentage of patients with <= 5 dilations in 6 months). Study participation ended after 6 months or if dysphagia grades 11 to IV recurred despite 5 treatment sessions. Results: No complications occurred with both treatments, There was no significant difference between the El and SB groups in the mean number of dilations (2.9; 95% Cl, 2.7-4.1 vs 3.3; 95% Cl, 2.3-3.61; P = .46) or the success rate (80.6% vs 67.7%, P = .26 and 96.2% vs 80.8%, P = .19). Limitations: In a small study with negative primary endpoints, secondary endpoints and subgroup analyses are hypothesis generating only Conclusions: This prospective trial demonstrated that El of gastroesophageal anastomotic strictures is a safe therapy and equivalent to SB as a primary therapy. El can be used as an alternative or additional therapy to SB. (Registered with Current Controlled Trials, Ltd, registration number ISRCTN81239664.) (Gastrointest Endosc 2009;70:849-55.)
