Background. ERCP is customarily performed with the patient in prone position. For patients intolerant of prone positioning, ERCP in left lateral decubitus (LLD) position offers a potential alternative. Aims. To compare efficacy and safety of ERCP in the LLD position versus prone position. Methods. Consecutive ERCP reports from August 2009 to October 2010 at Mayo Clinic Arizona were reviewed. Inclusion criteria. Age > 18 years, native papilla, and biliary indication. Primary outcome measure. Bile duct cannulation rate. Secondary outcomes. Times to ampullary localization and bile duct cannulation and complication rate. Results. ERCPs reviewed from 59 patients in two positions: 39 prone and 20 LLD. Cannulation Rate. 100% prone versus 90% in LLD ( ). Median (IRQ) times. (1) Ampullary localization: 90 sec (70–110) prone versus 100 sec (80–118) ( ); (2) bile duct cannulation: 140 sec (45–350) prone versus 165 sec (55–418) LLD ( ). Complications. No periprocedure; postprocedure 4 (10%) prone versus 3 (15%) LLD ( ). Conclusion. ERCP performed in LLD position allowed deep bile duct cannulation in 90% of patients without significantly increased procedural times or rate of complications as compared to prone position.
