A: Flat lesion 0-IIa visualized with high-definition white light and surface enhancement; B: Same lesion visualized … The overall number and size of the lesions, protruding or nonprotruding, found with HD+ plus i-Scan and standard white light are shown in Table Table3.3. The HD+ plus i-Scan technique identified a significantly larger number of lesions smaller from than 10 mm, either protruding or nonprotruding, than standard white light (P < 0.0001); the difference was not significant for lesions measuring 11-20 mm, 21-30 mm, and > 30 mm. Colonoscopies performed with HD+ with i-Scan technique also identified a significantly larger number of overall lesions and nonprotruding lesions smaller than 10 mm than did standard white light (P < 0.0001 and P < 0.

022, respectively), while the difference was not different for larger lesions, either protruding or nonprotruding. The differences were not significant considering screening, diagnostic, and surveillance colonoscopies. Table 3 Number and size of protruding and nonprotruding lesions found with high-definition+ with i-Scan and standard white-light colonoscopy Among the 154 nonprotruding lesions, histological report was available for 133 lesions, because in 21 cases, resected specimens were missed during colonoscopy (Table (Table4).4). Adenoma detection rate was significantly higher with HD+ plus i-Scan mode than with standard white light only for lesions smaller than 10 mm (32/35 vs 19/27, P = 0.05), while the difference was not significant for larger adenomas.

Table 4 Histological report of nonprotruding lesions The number of procedures managed by the four endoscopists and the distribution of HD+ plus i-Scan and standard white-light colonoscopies, with the mean numbers of lesions found by each one. The lesion detection rates were very similar for all four. The cumulative mean number of lesions per procedure detected with the two techniques was significantly higher with the HD+ plus i-Scan than with standard white-light imaging (mean �� SD, 1.82 �� 2.89 vs 0.95 �� 1.35, P < 0.0001). In fact, each of the four endoscopists identified twice as many lesions with the HD+ plus i-Scan as with standard white-light imaging. The overall withdrawal time, reported only for screening colonoscopies, did not significantly differ between procedures performed with the HD+ plus i-Scan and standard white light (8.4 �� 1.

2 min vs 8.3 �� 1.4 min, respectively) (Table (Table55). Table 5 Procedures performed by the four endoscopists using the two techniques DISCUSSION To date, only one study has evaluated the impact of the routine use of i-Scan with TE mode and HD+ imaging in the detection of mucosal lesion Batimastat during the withdrawal phase of colonoscopy, compared to standard white-light imaging, in a large series of patients in clinical practice[45].
