Abstract Severe caustic injury to the gastrointestinal tract carries a high risk of luminal strictures. The aim of this retrospective study was to identify predicting factors for progress of caustic injury to gastric outlet obstruction (GOO) and esophageal strictures (ES), using modified endoscopic mucosal injury grading scale. We retrospectively reviewed medical records of patients with caustic injuries to the gastrointestinal tract in our hospital in the past 7 years. We enrolled 108 patients (49 male, 59 female, mean age 50.1 years, range 18-86) after applying strict exclusion criteria. All patients received early upper gastrointestinal endoscopy within 24 hours of ingestion. Grade III stomach injuries were found in 58 patients (53.7\%); 43 (39.8\%) esophageal, and 13 (12\%) duodenal. Of the 108 patients, 10 (9.3\%) died during the acute stage. Age over 60 years (OR 4.725, P = 0.029) was an independent risk factor of mortality for patients after corrosive injury. Among the 98 survivors, 36 developed luminal strictures (37.1\%): ES in 18 patients (18.6\%), GOO in 7 (7.2\%), and both ES and GOO in 11 (11.3\%). Grade III esophageal (OR 3.079, P = 0.039) or stomach (OR 18.972, P = 0.007) injuries were independent risk factors for obstructions. Age ≥ 60 years was the independent risk factor for mortality after corrosive injury of GI tract. Grade III injury of esophagus was the independent risk factor for development of ES. Grade III injury of stomach was the independent risk factor for development of GOO.
