Many factors cause postoperative hepatic dysfunction, and anesthetic agents and type of surgery are belived to contribute to hepatic dysfunction. The authors planned this study to evaluate the effect of different anesthetic agents (sevoflurane, desflurane, enflurane or propofol) on liver enzymes in the patients who undergone laparoscopic cholecystectomy.

80 patients were randomly selected from among those who had undergone cholecystectomy and divided into 4 groups; an enflurane group (n = 20), a sevoflurane group (n = 20), a desflurane group (n = 20) and a propofol group (n = 20). Preoperative values of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) were compared with those on postoperative days 1 and 3 in all groups.

In all groups, ALT and AST were significantly elevated after operation, and then showed a decrease 3 days after operation, but remainrd of above preoperative levels (P < 0.05). However, no differences were observed between the 4 groups (P < 0.05).

We consider that propofol, sevoflurane, desflurane and enflurane are equally usable and that they have little effect on liver function after laparoscopic cholecystectomy.
