The causes of acute pancreatitis in Finland are alcohol overuse (60%), cholecystolithiasis (20%) and idiopathic (i.e. etiology unknown)(20%). Acute pancreatitis may recur in over half of cases and may be fatal in severe cases in 30%. Majority of idiopathic pancreatitis are caused by microlithiasis in gall bladder. The purpose of this randomized study is to prevent recurrence of idiopathic pancreatitis by performing laparoscopic cholecystectomy compared to non-operative group in 2 years follow-up of patients.

Study Start Date: January 2009
Estimated Study Completion Date: December 2015

Arms Assigned Interventions
Experimental: 1:Laparoscopic cholecystectomy
Procedure: Laparoscopic cholecystectomy
Other Names:
  • idiopathic pancreatitis
  • cholecystectomy
No Intervention: 2:controls
non-surgical control group

Detailed Description:

Etiologic investigations include serum amylase, lipase, triglyceride and calcium determination, as well as abdominal ultrasound scanning. Alcohol consumption is asked by using WHO audit test. After etiology of acute pancreatitis has been confirmed as idiopathic, 100 patients are randomized to laparoscopic cholecystectomy and 100 patients to follow-up of 2 years. Five to seven Finnish university and main central hospitals are participating the study.
