Narrow Band Imaging with Magnification Can Pick Up Esophageal Squamous Cell Carcinoma More Efficiently Than Lugol Chromoendoscopy in Patients after Chemoradiotherapy

Table 3

Number of lesions detected by NBI with magnification versus Lugol chromoendoscopy.

	NBI with magnification	Lugol chromoendoscopy
	𝑛 (%)	𝑛 (%)
SCC; (4 lesions)	4 (100)	4 (100)
HGIN; (2 lesions)	2 (100)	2 (100)
Other; (66 lesions)	1 (1.5)	66 (100)

NBI: narrow band imaging, SCC: squamous cell carcinoma, HGIN: high-grade intraepithelial neoplasia.
