The disadvantages of pull-type sphincterotome led to develop a new sphincterotome. The characteristic features of new antegrade sphincterotome are: it is inserted ready to use; the direction of cutting is strictly determined; fully controlled depth of the cut. Thanks to shaping as it hook the sphincterotome has been extracted cutting the circular layer only. The cutting wire is located between two teflon catheters preventing the longitudinal muscle layer from being damaged. The distance between the catheters determines the depth of the cut. Endoscopic transpapillary antegrade sphincterotomy developed by Dr. Dovbenko -(ASD) performance in such case allowed: to manage the papillary stenosis; to treat complicated form of gallstone disease; In research group this method allowed to avoid cholecystectomy in 71,2 % of cases', 'detailedDescription': 'Sph of Oddi consists of a circular inner muscle layer and a longitudinal outer muscle layer. The circular layer does not depend on the duodenum. The longitudinal layer passes from the wall of the duodenum and separates ascending and descending parts superimposing over its circular layer. The arrangement of these layers towards each others is constant. Mostly ERCP complications are caused by the interventions in major papilla and remain at a high level of frequency up to 23 % Cutting all the layers of duodenum leads to bleeding up to 3 %. The perforation might happened up to 1 % Destruction of the opening mechanism after sphincterotomy leads to develop of reflux cholangitis, acute cholecystitis. It is possible to avoid further cholecystectomy only in 10% of patients. Incapability of performing the retrograde sphincterotomy in patients with extended papillary stenosis led to the creation of a new method - ASD. Retrograde and antegrade sphincterotomies are analysed. 750 patients underwent ASD within 7 years 65 % in urgent cases . Relative risk of complication after ASD performing 3 times less. Taking into consideration possible post-ASD inner edema, plastic biliary/pancreatic stent(s) are required during 5-10 days after. Standard methods for post ERCP pancreatitis prevention must be applied in all cases. The new method performed some selective. First of all young patient with alone stone in the common bile duct, women after after childbirth. secondly, elderly patient were cured by ASD. And as well as a group of patients with severe comorbid diseases, such as renal failure, acute myocardial infarction. In our research, in two patients with AIDS was performed ASD. They were on special treatment after being diagnosed with HIV-infection, within 2 years. It was SSC. Papillary stenosis and cholangiolithiasis were cured successfully. The use of ASD with preservation of the closure function of the sph. Oddi allowed to avoid cholecystectomy in 71.2%. ASD can be performed new design of sphincterotome. It takes into account the anatomical structure of sph. Oddi and is recommended as an alternative to standard sphincterotomy, balloon dilatation and drainage interventions (RR 0,55 \\[95%CI 0,18 to 1,67\\].
