Risk Factors for Esophageal Stricture in Grade 2b and 3a Corrosive Esophageal Injuries.

BACKGROUND AND PURPOSE: Publications document the risk of developing esophageal stricture as a sequential complication of esophageal injury grades 2b and 3a. Although there are studies describing the risk factors of post-corrosive stricture, there is limited literature on these factors. The aim of this study was to evaluate the different factors with post-corrosive esophageal stricture and non-stricture groups in endoscopic grades 2b and 3a of corrosive esophageal injuries. METHODS: Data were retrospectively analyzed in the patients with esophageal injury grades 2b and 3a between January 2011 and December 2017. RESULTS: One hundred ninety-six corrosive ingestion patients were admitted with 32 patients (15.8%) in grade 2b and 12 patients (6.1%) in grade 3a and stricture was developed in 19 patients (61.3%) with grade 2b and in 10 patients (83.3%) with grade 3a. The patients' height of the non-stricture group was greater than that of stricture groups (2b stricture group, 1.58 ± 0.08 m; 2b non-stricture group, 1.66 ± 0.07 m; p < 0.004; 3a stricture group, 1.52 ± 0.09 m; 3a non-stricture group, 1.71 ± 0.02 m; p < 0.001). Omeprazole was more commonly used in the non-stricture than stricture group (26.3% in the 2b stricture group, 69.2% in the 2b non-stricture group, p = 0.017; 50% in the 3a stricture group, 100% in the 3a non-stricture group, 1.71 ± 0.02 m, p = 0.015). CONCLUSIONS: The height of patients may help to predict the risks and the prescription of omeprazole may help to minimize the risks of 2b and 3a post-corrosive esophageal stricture.
