The Effect of Indigocarmine on Improvement of the Polyp Detection Rate during Colonoscopic Examination with Hood Cap: Sang Chang Kwon, Sung Won Choi, Seong Ho Choi, Hee Seung Park, Seung Heon Lee, Bong Gun Kim, Eun Hee Seo, Mun Jang, Seung Min Ryu, Dong Hyun Kim, Young Hoon Kim, Jun Ouk Ha, Jae Seung Lee; Intest Res 2014;12(1):60-65.

<b>Background/Aims</b><br/>

Hood cap-assisted chromocolonoscopy using indigocarmine is expected to improve the detection rate of colorectal polyps, especially adenomatous polyps. Therefore, aim of the present study was to evaluate the usefulness of hood cap-assisted chromocolonoscopy in routine colonoscopic examinations.

Methods

From January, 2013 through March, 2013, a total of 86 patients were enrolled (M:F=33:53, mean age=60 years). For each patient, hood cap-assisted colonoscopic examination was performed, followed by hood cap-assisted chromocolonoscopy using 0.2% indigocarmine from the cecum to the hepatic flexure. Total numbers and characteristics of polyps were compared before and after indigo carmine dye spraying.

Results

Prior to dye spraying, 48 polyps were found in 37 patients, and after dye spraying, 53 additional polyps were found in 34 patients. Of these undetected polyps, 45 (85%) were small sized polyps (≤0.5 cm). Histologically, 19 (36%) were adenomatous polyps, and of these, 15 (28%) were tubular adenomas and 4 (8%) were serrated adenomas. As for the polyp detection rate, there was no difference between the expert and the non-expert groups.

Conclusion

Hood cap-assisted chromocolonoscopic examination using indigocarmine was helpful in detecting cecum and ascending colon polyps, especially small sized polyps (<0.5 cm) and neoplastic polyps.

Efficacy of Hood-cap Assisted Colonoscopy; Comparison with Conventional Colonoscopy: Sung Won Choi, Hee Seung Park, Jae Seung Lee, Sang Yon Hwang, Sung Dong Kwak, Seong Ho Choi; Intest Res 2012;10(3):280-288. Published online July 31, 2012; DOI: https://doi.org/10.5217/ir.2012.10.3.280

Background/Aims
A few studies showed that hood-cap assisted colonoscopy (CAC) had improved cecal intubation rate and cecal intubation time but did not help in finding colon polyps in comparison with conventional colonoscopy (CC). However, other studies have shown different results. Therefore, we investigated the efficacy of CAC for the cecal intubation time and polyp detection rate. Methods: Patients for colonoscopy in Busan St. Mary's Medical Center were enrolled to this randomized controlled trial between July 2010 and September 2010. The evaluated outcomes were polyp detection rate, adenoma detection rate, and cecal intubation time in all patients, in difficult cases (history of previous abdominal or pelvic surgery, obesity, old age), and in the expert and non-expert groups. Results: A total of 260 patients enrolled in this study were randomly allocated to the CAC group (n=130), or CC group (n=130). The overall cecal intubation time was shorter in the CAC group (5.7±3.4 min vs. 7.8±5.7 min, P＜0.001). The polyp detection rate was higher in the CAC group (58.4% vs. 43%, P=0.008). The cecal intubation time in the expert and non-expert groups were shorter in the CAC group (expert: 4.1±2.2 min vs. 5.5±2.0 min, P=0.001; non-expert: 6.7±3.7 min vs. 9.4±5.9 min, P=0.001). Conclusions: The use of CAC improved the detection rate of colon polyps and shortened the cecal intubation time for both the expert and non-expert groups. (Intest Res 2012;10: 0-288)
