Abstract

Background: For patients with sphincter of Oddi dysfunction and abnormal pancreatic basal sphincter pressure, additional pancreatic sphincterotomy has been recommended. The outcome of endoscopic dual pancreatobiliary sphincterotomy in patients with manometry-documented sphincter of Oddi dysfunction was evaluated. Methods: An ERCP database was searched for data entered from January 1995 to November 2000 on patients with sphincter of Oddi dysfunction who met the following parameters: sphincter of Oddi manometry of both ducts, abnormal pressure for at least 1 sphincter (≥40 mm Hg), no evidence of chronic pancreatitis, and endoscopic dual pancreatobiliary sphincterotomy. Patients were offered reintervention by repeat ERCP if clinical symptoms were not improved. The frequency of reintervention was analyzed according to ducts with abnormal basal sphincter pressure, previous cholecystectomy, sphincter of Oddi dysfunction type, and endoscopic dual pancreatobiliary sphincterotomy method. Results: A total of 313 patients were followed for a mean of 43.1 months (median, 41.0 months; interquartile range: 29.8-60.0 months). Immediate postendoscopic dual pancreatobiliary sphincterotomy complications occurred in 15% of patients. Reintervention was required in 24.6% of patients at a median follow-up (interquartile range) of 8.0 (5.5-22.5) months. The frequency of reintervention was similar irrespective of ducts with abnormal basal sphincter pressure, previous cholecystectomy, or endoscopic dual pancreatobiliary sphincterotomy method. Of patients with type III sphincter of Oddi dysfunction, 28.3% underwent reintervention compared with 20.4% with combined types I and II sphincter of Oddi dysfunction (p = 0.105). When compared with endoscopic biliary sphincterotomy alone in historical control patients from our unit, endoscopic dual pancreatobiliary sphincterotomy had a lower reintervention rate in patients with pancreatic sphincter of Oddi dysfuntion alone and a comparable outcome in those with sphincter of Oddi dysfunction of both ducts. Conclusion: Endoscopic dual pancreatobiliary sphincterotomy is useful in patients with pancreatic sphincter of Oddi dysfunction. Prospective randomized trials of endoscopic biliary sphincterotomy alone versus endoscopic dual pancreatobiliary sphincterotomy based on sphincter of Oddi manometry findings are in progress.
