Endoscopic Retrograde Cholangiopancreatography-Induced Severe Acute Pancreatitis

Background/Aims: There is scant information in the literature about the outcomes of endoscopic retrograde cholangiopancreatography (ERCP)-induced severe acute pancreatitis (ESAP). Compared to other causes, higher morbidity and mortality have been reported in ERCP-induced acute pancreatitis. We undertook this study to determine the differences between ESAP and SAP due to other causes (OSAP). Methods: We retrospectively identified all cases of SAP admitted to our institution during the years 1992-2001. We reviewed the medical records of all SAP patients to obtain information on demographics, interventions, local and systemic complications and outcomes.Results: We identified 207 patients with SAP, of whom 16 (7.7%) had ESAP and 191 OSAP. There was no difference between ESAP and OSAP with regard to demographics, clinical interventions, local and systemic complications and outcomes. Both groups had a similar mortality (25 vs. 18%).Conclusion: ESAP has a similar morbidity and mortality compared to OSAP
