Plain-language summary
Choledocholithiasis is a common and frequently occurring disease in China, accounting for 15.3% \~ 31.7% of the total cholelithiasis.According to its source, can be divided into primary and secondary choledocholithiasis.For large choledocholithiasis, it is difficult to remove all calculi after dilatation of large diameter balloon or mechanical stone following alone.Therefore, we used the method of balloon dilation combined with mechanical lithotripsy after EST.There are few researches on the sequence of balloon dilation and mechanical lithotripsy at home and abroad, and there is no unified standard.
Through the ERCP balloon expansion of duodenal papilla sphincter and mechanical lithotripsy in the treatment of common bile duct calculi in patients with clinical observation, the balloon expansion and mechanical lithotripsy time order of take stone, stone residues rate and the influence of recent complications such as postoperative pancreatitis, ERCP in the treatment of huge stones optimization procedure was formulated.
