RESUMO
The proposed method of common biliary duct cannulation is simple, easily performed and permits studying bile hydrodynamics biligenesis for a necessary time. Tightness of the system is completely preserved after removal a choledochostomical tube. Walls of the invaginated stump of the cystic duct are swiftly abated as a result of hydrostatic pressure and cover its gap. The presence of purse string kapron suture in a stump orifice creates an obstacle to deinvagination. Good reparation properties of serous and subserous membranes, covering the biliary duct, promote rapid closing of stoma. Effectiveness of the proposed method of common biliary duct cannulation by means of the invaginated stump of the cystic duct is confirmed by the smooth postoperative course and absence of a biliary fistula after the tube removal.
