Summary

Endoscopic retrograde cholangiopancreatography (ERCP) has been widely used in diagnosis and treatment of pancreaticobiliary diseases. Traditionally, ERCP has been performed in the prone position. The prone position for ERCP can facilitate selective bile duct cannulation, offer a better fluoroscopic image of pancreaticobiliary anatomy, and prevent aspiration of gastric contents. However, in cases of difficult in the prone position, ERCP has been performed in the left lateral or supine position. Compared with the prone position, left lateral position is more comfortable for patients, especially with limitation for cervical movement including cervical cord injury, cervical spine operation, parkinson's disease, contracture due to cerebral infarction, and allow more easy passage of the scope through the pharynx, and useful to secure airway. However, in the left lateral position, it is difficult to obtain fluoroscopic image of right hepatic duct and intrahepatic bile duct.

In cases of severe abdominal pain, severe abdominal distension, large amount of ascites, recent abdominal surgery or cervical spine surgery, intra-abdominal catheter insertion, severe obesity, it is difficult to position in prone or left lateral, therefore, ERCP may be performed in the supine position. In supine position for ERCP, there has been documented increased risk of cardiopulmonary adverse event and decreased success rate of selective bile duct cannulation.

There have been reported the efficacy and safety between the prone position and supine position for ERCP in several studies. We aimed to evaluate the efficacy and safety between the prone position and left lateral position for ERCP in this prospective, randomized study.

Interventions

PROCEDURE

Endoscopic retrograde cholangiopancreatography

1. Endoscopic retrograde cholangiopancreatography is started using conventional duodenoscope (TJF 240 or 260V, Olympus Optical Co., Ltd, Tokyo, Japan) in randomly assigned left lateral position or prone position. 2. Selective bile duct cannulation is performed using wire-guided cannulation. 3. In case of difficult cannulation, precut is performed using a needle-knife. 4. After selective cannulation, cholangiogram is obtained using ERCP catheter, and endoscopic sphincterotomy and/or endoscopic papillary balloon dilation is performed.
