Efficacy of endoscopic retrograde cholangiopancreatography combined with electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system in treatment of difficult choledocholithiasis
Objective To investigate the safety and efficacy of endoscopic retrograde cholangiopancreatography(ERCP)combined with electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system in the treatment of difficult choledocholithiasis.Methods A retrospective analysis was performed for the clinical data of 12 patients with difficult choledocholithiasis who underwent ERCP and electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system in Department of Gastroenterology,Jilin People's Hospital,from May to November 2022.The clinical effect of lithotripsy and lithotomy was observed,and postoperative complications and time of surgical operation were assessed.Results Among the 12 patients,11(91.67%)were successfully treated by electrohydraulic lithotripsy under direct view,9(75.00%)achieved first-attempt success in lithotripsy,and 11(91.67%)had complete removal of calculi;1 patient was found to have stenosis of the bile ducts caused by multiple biliary tract surgeries,and grade Ⅱ intrahepatic bile duct stones above the sites of stenosis were removed under direct view,but there were still residues of grade Ⅲ intrahepatic bile duct stones,which led to the fact that complete calculus removal was not achieved.The mean time of ERCP operation was 91.3±26.2 minutes,including a time of 41.8±22.2 minutes for energy lithotripsy.There were 2 cases of postoperative biliary tract infection which were improved after anti-infective therapy,2 cases of hyperamylasemia which were not given special treatment,and 3 cases of mild pancreatitis which were improved after symptomatic medication,and there were no complications such as bleeding and perforation.Conclusion ERCP combined with electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system is safe,effective,and feasible in the treatment of difficult choledocholithiasis.
