Objective: To investigate if ERCP (endoscopic retrograde cholangiopancreatography)conducted with patient in supine position is as safe and effective as in traditional prone position.
Methods: 52 consecutive patients who were undergoing ERCP in our center were randomized to be operated in either prone or supine position. Demographic and clinical characteristics of the 52 study patients were recorded. Difficulty of cannulation of the ampulla of Vater was assessed with the Freeman Score. Total procedure time, intra-operative vital signs (Heart rate, oxygen desaturation and mean artery pressure), patient tolerance were also recorded and compared.
Results: There was no statistically difference for the Freeman score and procedure time between the two groups. Vital signs were compared in the two groups respectively on the basis of 4 steps during the procedure: enter of endoscope; canulation; sphincterotomy and nasobiliary drainage, no significant difference were found between the two groups during each step, while heart rate and MAP during enter of endoscope in both supine (p=0.01;p=0.001) and prone group (p=0.027;p=0.021) increased significantly compared to base line level.
Conclusion: We believe that ERCP could be performed with the patient in the supine position since it is as safe and effective as that in prone position.
