In group A (n = 25), BC performed following SC detected 15 additional Dasatinib polyps, resulted in 107%

additional detection rate. In group B (n = 24) SC performed following BC detected 1 additional polyp, resulted in 11% additional detection rate. Additional detection rate ratio, which represents the probability of missing a polyp during the first procedure with SC compared to the first procedure with BC is 107/11 = 9.72. This ratio is compared to published additional detection rate ratios of 2.56 (PDR) and 1.86 (ADR) in the Third Eye Retroscope and Cap fitted Colonoscopy tandem studies, respectively. Conclusion: BC using the balloon-colonoscope and withdrawal technique is safe, easy to use and demonstrates substantial increase in PDR during colonoscopy. Key Word(s): 1. CRC; 2.

Harbin Medical PLX4032 mouse University Objective: To discuss the difference between of Sodium Phosphates Oral Solution and Polyethylene Glycol-Electrolyte Powder in intestinal cleaning before colonoscopy. Methods: 107 patients was divided into 2 groups at ramdom, and Analysis the difference after they take Sodium Phosphates Oral Solution (Group A) and Polyethylene Glycol-Electrolyte Powder (Group B) seperatedly. RESULTS: The effective rate of group A and B was 75.68% and 77.14% respectively,

and the amount of residual feces was close. Results: The this website effective rate of group A and B was 75.68% and 77.14% respectively, and the amount of residual feces was close. Conclusion: There was no significant difference between two grouops in intestinal cleaning. The application scheme of one bottle of Sodium Phosphates Oral Solution should be promoted clinically.

Our aim was to determine the success rate of repeat ERCP with a failed ERCP procedure. Methods: A review of 168 repeat ERCP procedures was performed at Beijing Frend Hospital affiliated to the Capital medical university in the year2003–2013. Results: 168 endoscopy was repeated after unsuccessful procedures, and access to the desired duct was achieved in 90%(151/168) of repeat attempts. No complications occurred with repeat ERCP. Of the 17 patients who underwent failed repeated ERCP, 6 was not available for the follow-up study, 6 had metastatic cancer, and the other had pancreas divisum. Conclusion: Repeat ERCP yields an 90% success rate. This leads to an overall success rate of 91.0% Key Word(s): 1. ERCP; 2. canulation; 3. endoscopy; 4.
