Savary-Guilliard Dilators for Management of Corrosive Esophageal Strictures without using Fluoroscope: Five -year Experience in Pakistani Population

Abstract

Objective: To evaluated the safety and effectiveness of Savary-Guilliard dilators in corrosive
esophageal strictures without using fluoroscopic monitoring.
Methods: A total of 307 patients with corrosive esophageal strictures who underwent
endoscopic dilatation using Savary-Guilliard dilators were included in the study. Procedures were
repeated after every 2-4 weeks to assess the outcome and further need of dilatation. Treatment
was considered successful if the patient was able to tolerate a solid/semisolid meal for a period of
>6 months without further need of dilatation.
Results: Nine hundred eighty three dilatations were performed in 307 patients. The mean
number of sessions performed per patient was 3.2. Treatment success was obtained in 277
patients (90.2%). Treatment failure was noted in 18 patients (5.9%) and 12 patients (3.9%) lost to
follow up. Perforation occurred in 8 (2.6%) patients that were managed conservatively.
Conclusions: Dilatation of corrosive esophageal strictures with Savary-Guilliard dilators
without using fluoroscope is efficacious and safe.
