Baseline characteristics comparing endoscopic sphincterotomy with large balloon dilation (EPLBD) versus endoscopic sphincterotomy (EST).
| Trials | Site | Number of patients | Stone size (diameter, mm) | EPLBD procedure | The length of the sphincterotomy | ||||
|---|---|---|---|---|---|---|---|---|---|
