Table 3

Comparison of the clinical characteristics and severity of corrosive injury between patients with and without gastric outlet obstruction (GOO).

	GOO; 𝑁=18	Non-GOO; 𝑁=80	𝑃
Age (years, mean ± SD)	50.9 ± 14.9	47.6 ± 17.8	0.445
Gender (M/F)	8/10	38/42	0.814
Acid/alkali	17/1	69/11	0.457
Grade III esophagus injury	9 (50%)	27 (33.8%)	0.279
Grade III stomach injury	18 (100%)	31 (38.8%)	<0.001
Grade III duodenum injury	7 (43.8%)	6 (8%)	<0.001
