Observational study on cannulation rate during ERCP at hospital alor setar

ERCP (Endoscopic Retrograde Cholangiopancreaticography) was introduced in this hospital in late 1995. Since then, a lot of improvement have been achieved in the management of biliary tract diseases. Various general surgeons posted to this hospital have been trained in this procedure. A study was done to include all patients admitted for ERCP from August 1998 to July 1999. A total of 322 new patients with a mean of 26.9 cases a month had underwent this procedure. The duration of cannulation varied from 2 minutes to 45 minutes with a mean of 12 minutes. Cannulation rate by various surgeons differed. Overall success rate was 80%. Mortality was 0.6 % and morbidity was 0.9%. ERCP is safe and it takes at least 6 months of regular duodenoscopy before one can master the technique. Achieving 80% cannulation rate, has definitely reduced unnecessary common bile duct (CBD) explorations. During this study we have trained various surgeons in this procedure and at least 2 surgeons could be credentialled according to the guidelines provided by the Malaysian Society of Gastroenterology and Hepatology. During this study we have identified various reasons for the failure of cannulation which are useful for future training of endoscopists.
