説明

Any consensus has not been established in Japan regarding risk factors for post-ERCP pancreatitis. Therefore, to evaluate factors that stimulate the papilla, total operation time, was studied along with other factors previously reported. Among patients who underwent ERCP between August,2003 and May,2006,629 patients (average age of 65.5 years old and male: female ratio of 1.4: 1.0) were studied. The total incidence rate of post-ERCP pancreatitis was 4.1%. The patients were divided into two groups and compared: 1) those that“developed”and 2) those that“did not develop”pancreatitis. No differences were detected in the two groups for age, male: female ratio, common bile duct diameter, and main pancreatic duct diameter. The following parameters were significantly greater in the“developed”group: operation time: 47.5 vs.29.4 minutes; and imaging rate of pancreatic duct: 85.2% vs.63.5%. The time until deep insertion showed a longer tendency in the“developed”group: 17.4vs.8.7 minutes. These data suggest that operation time and imaging rate of the pancreatic duct are risk factors for post-ERCP pancreatitis.
