ABSTRACT

Background:

Colonoscopy is considered as a standard method for detecting various kinds of colorectal polyps. However,conventional colonoscopy( CC)still has the chance to miss some lesions. Literatures have already reported that transparent hood assisted colonoscopy( THAC)can improve the detection of colorectal polyps. However,the effect of black hood assisted colonoscopy( BHAC)on detection of colorectal polyps is still unclear.

Aims:

To evaluate the effect of BHAC on detection of colorectal polyps.

Methods:

A total of 1 076 patients underwent CC and BHAC from Sept. 2014 to April 2015 at Huadong Hospital Affiliated to Fudan University were enrolled in this prospective randomized controlled study. Baseline characteristics,cecal intubation time,withdrawal time,number of polyps,detection rate of polyps,location, size,morphology and pathological diagnosis of polyps between two groups were compared.

Results:

Compared with CC group,cecal intubation time was significantly shorter in BHAC group than in CC group[(6. 31 ± 3. 51)min vs.(7. 05 ± 4. 15)min,P=0. 002]. No significant differences in withdrawal time and rate of cecal intubation were found between two groups(P>0. 05). Detection rate of polyps was significantly higher in BHAC group than in CC group(65. 4% vs. 48. 7%,P=0. 004). No significant differences in size,morphology of polyps were found between two groups(P>0. 05).

Conclusions:

Compared with CC,BHAC could significantly improve the detection of colorectal polyps,and shorten cecal intubation time.
