Objective. To determine the prevalence of and factors associated with severe mucosal injury on signs/symptoms (oral lesions, drooling, vomiting, abdominal pain, dysphagia).

Results. 320 patients were investigated: 155 (48%) accidental and 165 (52%) intentional cases. In accidental intake, majority (84%) were <=6 years old [mean(SD) age: 3.7 (4.3) yrs, 59% males]. 10% had severe mucosal injury. The odds of severe injury increased in the presence of >=2 signs/symptoms: OR=7.0 for 2 and OR=62.2 for >2. In intential cases, the mean (SD) ae was 16 (1.6) years, 74% females. Severe mucosal injury was seen in 5% and associated with acidic agent (OR=54.8).

Conclusions. Severe mucosal injury on EGD occurred in 10% and 5% among accidental and intentional cases, respectively. In accidental cases, probability of severe injury increased in the presence of >=2 signs/symptoms. In intentional cases, acid intake was the only factor associated with severe injury. In the local setting, presence of these factors among patients with caustic ingestion will help identify high-risk patients who need EGD-guided management.
