Should patients undergoing ERCP be placed in the prone or supine position?

Area of Science:

• Gastroenterology
• Endoscopic Procedures

Background:

• Endoscopic retrograde cholangiopancreatography (ERCP) is commonly performed in prone or semi-prone positions.
• Supine positioning may offer advantages in airway control and anatomical visualization, while prone positioning is associated with lower aspiration risk.

Discussion:

• A prospective, randomized study by Tringali et al. compared ERCP performance in prone versus supine positions.
• The study evaluated outcomes in both experienced endoscopists and trainees, assessing procedural difficulty, time to papilla visualization, and ductal opacification.

Key Insights:

• No significant difference was observed in procedural difficulty between prone and supine positions for ERCP.
• Objective measures like time to papilla visualization and ductal opacification were equivalent.
• Overall technical success and complication rates were comparable across both patient positions.

Outlook:

• The findings suggest that both supine and prone positions are technically adequate for performing ERCP.
• Clinical practice should consider these results when interpreting patient positioning strategies.
• Further research may explore patient comfort and specific anatomical challenges in different positions.
