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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| First lithotripsy and then EPBD | Experimental | After successful selective bile duct intubation, contrast agent was injected to measure the thickness of the bile duct and the size of bile duct stones under fluoroscopy. For those meeting the inclusion criteria, sphincterotomy was performed first.Papillary sphincter incision after indwelling godet in bile duct, anti-popular character silk will be crushed stone on top into rubble after biliary tract, broken line to suitable size after the switch to expanding balloon EPBD and further kidney stones, papillary sphincter incision after indwelling godet in bile duct, anti-popular character silk will be crushed stone on top into rubble after biliary tract, broken balloon to suitable size after the switch to expansion, expansion size 10-12 mm, according to the lower bile duct diameter, expansion time of 30 seconds.Then, the stones were removed with a net basket or balloon, and the nasobiliary duct was placed to end the operation. |
|
| First EPBD and then lithotripsy | Experimental | After puncture of the papillary sphincter, the guide wire was indwelled in the bile duct, and the columnar dilating balloon was inserted in exchange. The dilation size was 10-12mm, and the dilation time was 30 seconds according to the diameter of the lower end of the bile duct.At the end of the expansion, the stones were broken to a suitable size using a one-piece gravel net basket.The calculi were removed by using a stone net basket or balloon, and the nasobiliary duct was placed to end the operation. |

|---|---|---|
| Lithotomy time | The time required from completion of papillary myotomy to completion of lithotomy, including the time of cylindrical balloon dilation | About 20 minutes |
| Stone residual rate | Routine indwelling of the nasobiliary duct was performed, and nasobiliary angiography before removal was performed to confirm the presence of residual stones | about 2 days |
