Improved detectability of small-bowel lesions via capsule endoscopy with computed virtual chromoendoscopy: A pilot study

Figures & data

Figure 1. Example of an angioectasia. Although some reddening can be seen on the conventional image, the lesion is more clearly visualized by CE-FICE. a: Conventional CE image. b–d: CE-FICE images derived from the three different wavelength settings (b = setting 1; c = setting 2; d = setting 3). CE = conventional endoscopy; CE-FICE = CE with flexible spectral imaging color enhancement.

Table I. Number of lesions detected by conventional CE and CE-FICE.

Lesion type	Conventional CE	CE-FICE
		Setting 1	Setting 2	Setting 3
Angioectasia	17	48*	45**	24
Erosion	20	27	33	31
UIceration	12	13	21	20
Tumor
Lymphangioma	40	45	44	40
Adenomatous polyp	1	1	1	1
Peutz-Jeghers polyp	7	7	7	7
GIST	5	6	4	4
Hemangioma	2	2	1	1

Abbreviations: CE = conventional endoscopy; CE-FICE = CE with flexible spectral imaging color enhancement; GIST = gastrointestinal stromal tumor.

*p = 0.0003 vs. conventional CE; **p = 0.001 vs. conventional CE (Wilcoxon test).

Figure 2. Increase in the number of angioectasias detected per FICE setting (vs. conventional CE). Abbreviations: CE = conventional endoscopy; FICE = flexible spectral imaging color enhancement.

Table II. Capsule video reading times*.

Conventional CE images	FICE images
	Setting 1	Setting 2	Setting 3
36 ± 6.9	36 ± 6.4	38 ± 5.8	35 ± 6.7

Abbreviations: CE = conventional endoscopy; FICE = flexible spectral imaging color enhancement.

Differences did not differ statistically.
