	72 (34.9)	56 (27.2)	62 (30.1)	16 (7.8)	206 (100)

Table 2 Esophageal stricture in relation to esophageal injury n (%)

Grade of esophageal injury	Stricture rate
Grade-0	0 (0)
Grade-1	0 (0)
Grade 2a	6 (37.5)
Grade 2b	9 (56.25)
Grade 3	1 (6.25)
Total	16 (100)

Table 3 Gastroscopic findings according to caustic substance n (%)

	Substance				Total (n = 206)
	Acidic (n =72 )	Alkaline (n = 56)	Liquid household bleach (n =62 )	Unknown content(n = 16)
Severe gastric injury	29 (14)	6 (2.9)	2 (1)	1 (0.5)	38 (18.4)

Table 4 Severity of esophageal lesions in relation to clinical findings n (%)

Clinical findings	Grade of esophageal injury
	0	1	2a	2b	3
Normal (n = 57) (27.7%)	37 (17.9)	9 (4.4)	9 (4.4)	2 (1)	0
Positive clinical findings (n = 149) (72.3%)	49 (23.8)	40 (19.4)	33 (16)	26 (12.6)	1 (0.5)

Table 5 Severity of gastric lesions in relation to clinical findings n (%)

Clinical findings	Gastric injury
	Normal	Severe
Normal (n = 57) (27.7%)	49 (23.7)	8 (3.9)
Positive clinical findings (n = 149) (72.3%)	117 (56.8)	30 (14.6)

Gastroscopy could not be performed in 2 (1%) patients with positive clinical findings because of severe esophageal edema.
