The aim of this study is to demonstrate that patients with high risk of choledocholithiasis who undergo ERCP only for patients with choledocholith in the EUS examination[EUS-ERCP group] have less negative outcomes (including false-negative results and procedure-related complications) than patients who undergo ERCP in all patients with high risk of choledocholithiasis[ERCP group]. The primary outcome is the incidence of negative outcomes (including false-negative results and procedure-related complications) in both groups. The secondary outcomes included days of hospitalization and the rate of diagnostic ERC.
Several studies have shown that EUS testing prior to ERCP may reduce ERCP complications in patients with intermediate-risk choledocholithiasis. In other words, this results obtained by not performing ERCP in patients without choledocholith in the EUS examination. However, to the best of our knowledge, no prospective study has been conducted on the role of EUS in patients with high risk of choledocholithiasis. Therefore, we investigate the role of EUS screening in patients with high risk of choledocholithiasis. We compare the negative outcomes (including false negative and procedure-related complications of EUS and ERCP) of the 'EUS-ERCP group' in which ERCP is performed when necessary after the EUS examination and the 'ERCP group' in which ERCP is performed in all patients.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| EUS-ERCP group | Experimental | EUS is performed first, and when the examiner finds bile duct stone in the EUS examination, ERCP is performed to remove the stone. |
|
| ERCP group | Active Comparator | ERCP without EUS is performed in all patients. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| EUS | Device | Endoscopic ultrasound (EUS) is performed with radial scanning echo endoscope (Olympus GF UE260) by four endosonographers. EUS examination is performed first, and if there is choledocholith, ERCP is performed. |
| Measure | Description | Time Frame |
|---|---|---|
| Any negative outcomes related to either a false-negative diagnosis of choledocholithiasis or the endoscopic procedure | Negative outcomes associated with a false-negative diagnosis of choledocholithiasis were defined as follows: 1) diagnosis of choledocholithiasis during follow-up or 2) hospitalization for a condition likely associated with choledocholithiasis, such as biliary pancreatitis, cholangitis, or obstructive jaundice. Negative outcomes of endoscopic procedures were assessed according to the ASGE lexicon | 6 months after randomization |
| Measure | Description | Time Frame |
|---|---|---|
| Length of hospital stay | Length of hospital stay | 6 months after randomization |
| Measure | Description | Time Frame |
|---|---|---|
| The rate of diagnostic ERC (Endoscopic retrograde cholangiography) | The diagnostic ERC was defined as any ERC procedures in which no stone or sludge was removed during the procedure. | 6 months after randomization |
