Short-term results of treatment and cost-effect rates were analyzed in three groups of patients undergone traditional cholecystectomy, laparoscopic cholecystectomy and cholecystectomy through minilaparotomy. It was demonstrated that frequency of complications was less after operations through laparoscopy and minilaparotomy. Traditional approach had the most costs due to more number of postoperative complications, hospital stay after surgery and more number of analgesics. Cholecystectomy through minilaparotomy is most cost-effective due to high clinical effectiveness, short hospital stay and rare complications. This procedure does not require expensive devices and can be performed with regional anesthesia only. It is concluded that minimally invasive methods of cholecystectomy must be used more widely.
