title: Readmissions due to acute biliary edematous pancreatitis in patients without cholecystectomy.
abstract: OBJECTIVE
  Analyzing the readmission of patients with acute biliary edematous pancreatitis (ABEP) without cholecystectomy despite a previous episode of mild acute gallstone pancreatitis or lithiasic cholecystitis. Calculating the health costs associated with the non-performance of cholecystectomy.
  
  
  METHODS
  Prospective observational study conducted at a tertiary hospital from July to November 2014. The study has consecutively included inpatients suffering from ABEP who: a) had suffered a previous episode of mild acute gallstone pancreatitis or cholecystitis at least 2 weeks before readmission; and b) had not undergone cholecystectomy despite the lack of contraindications.
  
  
  RESULTS
  During the research period, 9 patients (7 females and 2 males) with a mean age of 65.3 years (standard deviation [SD] 19.2) were readmitted. The median number of days between the previous episode of ABEP or cholecystitis and the readmission was 114 days (interquartile range [IQR] 111.0). Reported median overall length of hospital stay was 10 days (IQR = 2.0). Patients underwent a mean of 2.8 (SD = 1.2) ultrasound scans, 1.3 (SD = 0.9) abdominal and pelvic CT, 0.8 (SD = 1.0) MRCP and 0.2 (SD = 0.4) ERCP. The mean cost per patient for each readmission, including hospital stay (143.0 €/day), Emergency Service (332.31 €) and tests performed was 2,381.70 €/patient.
  
  
  CONCLUSIONS
  Not performing a cholecystectomy within two weeks after a first episode of mild ABEP or cholecystitis contributes to patient readmission due to recurrent pancreatitis, resulting in avoidable treatment costs.
