Combination of Electronic Choledochoscopy and Holmium Laser Lithotripsy for Complicated Biliary Calculus Treatment: A New Exploration

The safety and efficacy of the combination of electronic choledochoscopy and holmium laser lithotripsy for complicated bile duct stones were assessed. In total, 20 patients participated in this study, which was conducted between 2012 and 2017. None of the patients were candidates for endoscopic retrograde cholangiopancreatography with stone extraction. Outcome measures included complete stone clearance and complications postprocedure. Mean stone size was 17±5.2 mm (8 to 30 mm) and mean number of stones was 1.7±1.3 (1 to 5). The mean number of laser sessions was 1.3±0.7 (1 to 4). A mean of 1.0 to 1.5 J/20 to 25 Hz was applied during laser lithotripsy sessions with a mean operative time of 67.8±24.8 minutes. The clearance rate of stone was 18/20 (90%). No mortality existed in this study; however, 1 patient developed acute pancreatitis. The combination of holmium laser lithotripsy and electronic choledochoscopy for complicated biliary calculi is safe, reliable, and minimally invasive and has low residual stone rate.

Advances of recurrent risk factors and management of choledocholithiasis

Gallstone disease is a common and frequently occurring disease in human, and it is the main disease among the digestive system diseases. The incidence of gallstone disease in western countries is about 5%-22%, and common bile duct stones (CBDS) accounts for 8%-20%. CBDS easily lead to biliary obstruction, secondary cholangitis, pancreatitis, and obstructive jaundice, even endanger life. Therefore, it needs timely treatment once diagnosed. The recurrence of choledocholithiasis after bile duct stones clearance involves complicated factors and cannot be completely elaborated by a single factor. The risk factors for recurrence of choledocholithiasis include bacteria, biliary structure, endoscopic and surgical treatment, and inflammation. The modalities for management of choledocholithiasis are endoscopic retrograde cholangiopancreatography (ERCP), laparoscopic or open common bile duct exploration, dissolving solutions, extracorporeal shockwave lithotripsy (ESWL), percutaneous radiological interventions, electrohydraulic lithotripsy (EHL) and laser lithotripsy. We compare the different benefits between surgery and ERCP. And finally, we make a summary of the current strategy for reducing the recurrence of CBDS and future perspectives for CBDS management.

Common bile duct stones - their presentation, diagnosis and management

Common Bile duct stones (CBD) continue to pose a significant problem both to the patient and the Surgeon. They increase the morbidity of a patient undergoing Cholecystectomy from less than 5% to as much as 20% and almost zero mortality to as high as 30%. Recent times have thrown up a fair share of controversy in the management of this condition both due to technological innovations and costreduction-pressures. The aim in CBD stone disease, as in any benign disease is to discover a therapeutic algorithm with minimal morbidity, no mortality and at reasonable cost. This can be achieved only by a thorough understanding of the disease and also the available diagnostic and treatment modalities.This article dicusses the diagnosis, investigation and therapy of Common Bile Duct Stones (CBD) and gives a therapeutic algorithm.

Endoscopic papillotomy, syn. sphincterotomy: results from the past two years

Endoscopic papillotomy, introduced in 1973, is now an established endoscopic procedure for treatment of various diseases of the papilla, bile duct, and pancreas. This article describes the use of this technique, the various instruments that can be employed, the instances in which it is indicated, and its associated complications and risks. Alternative treatments are also summarized.
