摘      要：Colonoscopy sometimes causes pain during insertion,especially in difficult ***-insufflation of air causes elongation or acute angulations of the colon,making passage of the scope difficult and causing *** previously reported a sedative-risk-free colonoscopy insertion technique,namely,Water Navigation Colonoscopy.Complete air suction after water infusion not only improves the vision,but also makes water flow down to the descending colon,while the sigmoid colon collapses and *** non-sedative colonoscopy can be carried out without pain in most cases,some patients do complain of *** of these patients have abnormal colon morphology,and the pain is caused while negotiating the hairpin bends of the *** hairpin bends of the colon should be negotiated by gently pushing the full-angled *** proximal 10-20 cm from the angulated part of the conventional colonoscope is stiff,with a wide turning radius,therefore,a conventional colonoscope cannot be negotiated through the hairpin bends of the colon without stretching them and causing *** passive-bending colonoscope has a flexible tip with a narrow turning radius,so that the scope can be negotiated through the hairpin bends of the colon with a minimum turning radius and minimal ***,the intubation and pain-reducing performance of the passive-bending colonoscope was assessed in difficult cases.
