Pulmonary function in women: comparative analysis of conventional versus single-port laparoscopic cholecystectomy.

OBJECTIVE: to evaluate the pulmonary function of women submitted to conventional and single-port laparoscopic cholecystectomy. METHODS: forty women with symptomatic cholelithiasis, aged 18 to 70 years, participated in the study. We divided the patients into two groups: 21 patients underwent conventional laparoscopic cholecystectomy, and 19, single-port laparoscopic cholecystectomy. We assessed pulmonary function through forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), and the FEV1/FVC ratio, measured before and 24 hours after the procedure. RESULTS: in both groups, FVC and FEV1 were lower in the postoperative period than those obtained in the preoperative period, with a greater reduction in the group undergoing conventional laparoscopic cholecystectomy. Regarding the FEV1/FVC (%) values, there was no statistically significant difference in any of the groups or times analyzed. CONCLUSION: there was a greater decline in FVC and FEV1 in the postoperative group of patients submitted to conventional laparoscopic cholecystectomy.
