TREATING SIMPLE BENIGN ESOPHAGEAL STRICTURES WITH SAVARY-GILLIARD DILATORS: IS THE RULE OF THREE STILL NECESSARY?

Abstract

ABSTRACT BACKGROUND: Bougies dilation is considered an effective technique for the treatment of simple benign esophageal strictures. The “rule of three” has been advocated to prevent reported adverse events such as bleeding and perforation. However, adherence to this rule has increased the cost and duration of treatment. OBJECTIVE: To demonstrate the safety and long-term benefits of progressive bougie dilations until reaching 15 mm (45Fr) in one single session endoscopy with non-adherence to the rule of three. METHODS: A retrospective analysis of a prospectively collected data of patients with simple benign esophageal strictures treated with multiple progressive bougie dilators until reaching 15 mm (45Fr) in one single session. RESULTS: The median age was 58 years (range 28-89), and 83.3% of patients were female. The main presenting symptom was dysphagia for solids in 11/12 cases (91.6%). The cause of their simple benign esophageal stricture was distributed as follows: 7/12 esophageal webs, 2/12 peptic stenosis, 2/12 Schatzki rings and one caustic injury. 75% required only one session for clinical success. No serious adverse events were described. No recurrence of symptoms was noted in a median follow-up of 20 months. CONCLUSION: The rule of three in patients with simple benign esophageal strictures secondary to esophageal webs, Schatzki rings and peptic strictures treated with Savary-Gilliard dilators is not necessary, showing good clinical results. Prospective studies with more patients are necessary.
