[Comparison of the results of laparoscopic cholecystectomy preformed in the usual way and with a lesser number of trocars].

Laparoscopic surgery is a part of the minimally invasive surgery. Its aim is to make on operation as valuable as the open one, or even more, with a smaller invasion or injury of the body. With the instruments improvement the operation would be possible without any remarkable organism injury. On the other hand, modifications of the operation techniques lead to progress. European technique of laparoscopic cholecystectomy using four trocars has changed. Procedures are performed with one trocar less. Two groups of two hundred patients each have undergone laparoscopic cholecystectomy. The operation in the first group was performed using four, and in the second group using three trocars. The aim of the investigation was to compare these two methods of laparoscopic cholecystectomy. The results analysis showed that laparoscopic cholecystectomy using three trocars did not cause either a higher complication rate, prolonged average operation time or longer duration of hospitalisation. The analgesics consumption was lower, sick-leaves were shorter, with smaller total costs, and cosmetic effect was better.
