Abstract

|
|
Laser laparoscopic cholecystectomy has rapidly become a popular method for removing the gallbladder,. The main advantages of this procedure are that it is less painful, less invasive, shortens the hospital stay, returns patients earlier to active
life,
and causes minimal scarring than traditional cholecystectomy.
This study was investigated the effects of laparoscopic cholecystectomy on pulmonary function., this investigation was designed to assess preoperative and postoperative pulmonary function, that is the forced vital capacity(FVC0 and the forced
expiratory
volume in the first second(FEV1) and blood gases (PaCO2, PaO2) and pH. These variables on the preoperative and the first postoperative days were taken in 45 patients having elective laparoscopic cholecystencotmy.
@ES the results were as follows:
@EN 1) The ratio male to female was 17 : 28 and averaged age was 52.6 years old(range : 29~79).
2) duration of operation procedure averaged 33.9 minutes(range, 10~70), and anesthetic time averaged 47.0 minutes(range, 15~120.).
3) Anagesics for postoperative pain was used in 22 patients(47%).
4) Postoperatively, the FVC and FEV1 were reduced by 78~79% of preoperative valuses in estimated volumes and percent of predicted. FEV1/FVC ratio was not changed. And then MMF was reduced by 30%, FEFR, FEE25, FEF50 and FEF75 were reduced by
15~20%
of
preoperative values.
5) Postoperatively pH and PaCO2 were not changed, and PaO2, SaO2 were reduced, but there were no clinical sginificance.
