[Minimising hospital costs in the treatment of bile duct calculi: a comparison study].

Introduction: The treatment of bile duct calculi associated with cholelithiasis is controversial. The hospital costs could be a decisive factor in choosing between the different therapeutic options.
Objectives: To compare the effectiveness and costs of two options in the treatment of common bile duct calculi: 1) One-stage: Laparoscopic cholecystectomy and bile duct exploration, and 2) Two-stage: sequential endoscopic retrograde cholangiopancreatography and laparoscopic cholecystectomy.
Material and Methods: A retrospective, observational study was performed on 49 consecutive patients with bile duct calculi and gallbladder in situ, treated consecutively and simultaneously over a two year period. The post-operate complication, hospital stay, number of procedures per patient, conversion to laparotomy, efficacy of removing the calculi, and hospital costs.
Results: There were no differences as regards the patient clinical features or morbidity. The mean post-surgical hospital stay for the One-stage group was less than that in the Two-stage group. Three patients of the Two-stage group required conversion to laparotomy. The median costs per patient were less for the One-stage strategy, representing an overall saving of 37,173€ during the period studied.
Conclusions: No significant differences were found between the two treatment options as regards efficacy or post-surgical morbidity and mortality, but there were differences in hospital stay and costs. The management of patients with gallstones in one-stage surgery represents a saving of 3 days hospital stay and 1,008€ per patient.
