Should ERCP be routine after an episode of “idiopathic” pancreatitis? A cost-utility analysis

摘要: Abstract Background: Patients often recover from an episode of acute pancreatitis with conservative therapy and without identified cause. The options include proceeding ERCP to identify treat occult common bile duct stone or performing the procedure only after a second idiopathic occurs. Methods: Decision analysis (SMLTREE software) was used determine incremental cost-utility. Variables were estimated search literature, utility involving health professionals familiar question, retrospective review hospital charts costs. Results: This model estimates gain for prompt approach 1.0 quality-adjusted life weeks per patient at cost $245 (Canadian). yields cost-utility ratio $12,740 (Canadian) year. result highly sensitive probability finding stone. Conclusion: Routine is marginal overall benefit, but more substantial benefit cost-effective in subgroup patients greater having (Gastrointest Endosc 1996;44:118-23.)
