Open versus laparoscopic cholecystectomy: a comparison of postoperative temperature

Abstract

Laparoscopic cholecystectomy has been shown to allow better postoperative pulmonary function than open cholecystectomy, with less incidence of lung atelectasis. As atelectasis following abdominal surgery is responsible for most febrile episodes in the first 48 h, it was postulated that with minimally invasive surgery there may be a parallel improvement in the incidence of postoperative fever. This study was designed to evaluate this hypothesis. Seventy-eight patients were randomly divided into two groups. Thirty-eight had an open cholecystectomy and 40 underwent the laparoscopic approach. Twenty-one of the 38 patients (55%) following open cholecystectomy had early febrile episodes compared with only 6 of the 40 (15%) in the laparoscopic cholecystectomy group. We concluded that there was a lower incidence of febrile episodes following laparoscopic cholecystectomy and suggest that this was related to improved pulmonary function and minimal surgical trauma.
