Minimally Invasive Phasic Treatment Protocol for the Treatment of Extrahepatic Bile Duct Stones

Abstract Objectives: To identify the optimal treatment for extrahepatic bile duct stones using endoscopy, laparoscopy, and the combination of the two in different conditions and to develop phasic treatment protocols for their minimally invasive treatment. Patients and Methods: Of 2718 cases of extrahepatic bile duct stones collected from June 2005 to December 2011, 50 were randomly selected to receive open bile duct exploration and T-tube drainage, serving as the control group. For the rest, a one-scope protocol, two-scope protocol (two-scope protocol A or two-scope protocol B), or three-scope protocol was adopted according to the specific conditions of stones and the endoscopic treatment results. The treatment outcomes and postoperative clinical indicators of the minimally invasive treatment protocols were analyzed and compared with those of the control group. Results: Among the 2668 cases of extrahepatic bile duct stones receiving the phasic minimally invasive treatment, the treatment success rate was 9...
