Hepatobiliary pelvic drainage

Hepatobiliary stones and stenosis are the main reasons for the current enterohepatic drainage. The traditional surgical method of hepatobiliary stones is to cut through the common bile duct, use stone clamps or gallstone spoons to dig, dig, and squeeze extrahepatically to remove the stones, and then perform hepatointestinal drainage. Up to 32% to 76%, and the reoperation rate is 30% to 56%. To summarize the lessons of past failures, it is necessary to end the intrahepatic calculi and narrow the situation with only extrahepatic treatment. Hepatobiliary calculi and stenosis The focus of surgery is not on excavation but on relief of hepatobiliary stenosis. Aiming at the situation of intrahepatic bile duct stones combined with stenosis, the method of widely exposing the intrahepatic bile duct was used to cut and shape the narrow part to form a "hepatobiliary pelvis", and then perform drainage with the bowel. This is a new surgical approach that can address stenosis and bile retention, reducing the possibility of stone residue and recurrence.
