title: [Is laparoscopic cholecystectomy minor invasive surgery?].
abstract: We conducted a comparative study to investigate whether or not laparoscopic cholecystectomy is less invasive and safer than abdominal subcostal laparotomy, using findings in blood pressure, heart rate, blood gas and endocrinological functions. In laparoscopic cholecystectomy, the patients' hospitalization period and expense for surgery were markedly reduced. However, those patients who underwent laparoscopic cholecystectomy had increases in blood pressure, heart rate, plasma cortisol and norepinephrine concentrations; it was assumed that these increases might be the result of reduced venous return to the heart which accompanied increased intra-thoracic and abdominal pressures, with reduction of cardiac output. In conclusion, since laparoscopic surgery is very advantageous for patients, we consider that for the success of this surgical procedure, it will be necessary to conduct safe anesthetic managements as well as to select patients carefully.
