AbstractLaparoscopic cholecystectomy (LPC) is increasingly used to treat symptomatic cholelithiasis. We compared the effects of cholecystectomy by subcostal incision to those of LPC on lung function and endocrine metabolic response. The effects of thoracic epidural analgesia for LPC were studied as well. Thirty patients undergoing elective cholecystectomy under general anesthesia were allocated to three study groups: group I, cholecystectomy by subcostal incision; group II, LPC; group III, LPC and epidural analgesia with 0.5% bupivacaine with epinephrine, followed by continuous epidural infusion of 6 mL of 0.5% bupivacaine. Forced vital capacity (FVC), peak expiratory flow, and forced expiratory volume in 1 s were measured with the patients in a half-sitting position. In all groups, sustained decreases in FVC, forced expiratory volume in 1 s, and peak expiratory flow were observed up to 24 h after surgery. Reduction of FVC was significantly more in group I compared with groups II and III (P less than 0.05). The FVC in group I decreased from 3.8 +/- 0.42 (SD) to 1.1 +/- 0.27 L (P less than 0.01), in group II from 3.6 +/- 1.46 to 2.1 +/- 0.94 L (P less than 0.05), and in group III from 3.8 +/- 0.92 to 2.8 +/- 0.90 L (P less than 0.05). In all groups, plasma glucose and cortisol increased after surgery compared with baseline levels (P less than 0.05). At 240 min after surgery, a small but significant decrease of cortisol was measured in group III (P less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
