Comparing the Safety and Efficacy of Savary-Gilliard and Balloon Dilatators.
Pak J Med Health Sci Jan ;13(2):249-51.

Background: Corrosive intake and subsequent esophageal stricture formation is a major health hazard in developing countries. The main stay of treatment for dysphagia resulting from corrosive intake is endoscopic dilatation of stricture. Two methods of dilatation are currently in wide use, push type dilators (Savary-Gilliard) and balloon dilators. Aim: To compare the safety and efficacy of Savary-Gilliard and Balloon dilatators in corrosive esophageal strictures. Methods: The study cohort included 60 patients who presented to our Department of Gastroenterology with dysphagia due to corrosive esophageal strictures between February 2016 to September 2017. During the procedure, half the patients were dilated with balloon dilatators and half with Savary-Guilliard dilators. All the dilatations were performed by experienced endoscopists . Results: A total of 159 dilatations were performed in 60 patients. 72 dilatations were performed with Savary- Gilliard dilators in 30 patients and 87 dilatations with balloon dilators in other 30 patients. Treatment success was obtained in 28/30 patients (9 3.3%) in Savary-Gilliard group and 27/30 patients (90%) in balloon dilator group. Treatment failure was noted in 5 patients , two in Savary-Gilliard group and three in balloon dilator group. No perforation was seen in Savary-Gilliard group while one perforation occurred in balloon dilator group. Conclusion: Both methods of stricture dilatation were safe and effective, although Savary-Gilliard dilators were slightly more effective and safer.
