Clinical Outcome of Endoscopic Dilatation Using Ultrathin Endoscope Assisted Method for Esophageal and Pyloric Stricture Related Corrosive Injury: 4 Years Retrospective Study

Abstract

Background: Corrosive injuries (CI) became medical problems related complications include esophageal, pyloric stricture, squamous cell carcinoma [1], physical and quality of life [2]. Endoscopic dilatation (ED) is primary therapy [3]. The ultrathin endoscope assisted method is potentially safe and useful in avoiding technical failure [4].
 Methods: Retrospective study of esophageal and/or pyloric stricture after CI who underwent di-latation at Soetomo General Hospital (July 2018 – July 2022). One-biweekly ED using Ultrathin Endoscope Assisted Method then continued by Through The Scope (TTS) balloon or Bougie dila-tor. Target diameter is 14mm. Clinical outcome included successful, refractory, recurrent rate and complications related procedures
 Results: Fifteen patients with stricture related CI. Eleven patients underwent ED with total 73 procedures. Mean age 31,45 years, Male 6(54,6%), suicide attempt 7(63,6%), acid agent 9(81,8%) located at esophagus 3(27,3%), pylorus 3(27,3 %), or both 5(45,4%). Number of esophageal dilata-tion to achieve target 14mm was 1-2 and 2-15 procedures for simple and complex stricture with overall successful, recurrent and refractory rate were 75%, 12.5% and 12.5% respectively. Pyloric dilatation outcome were 62.5%, 25% and 12.5% for successful, recurrent and refractory rate re-spectively. 
 Conclusions: Stricture-related corrosive injury has predominantly complex anatomical structure, more sessions are required and lower clinical outcome
