Objective: The purpose of this study was to determine whether obesity increases risk in performing laparoscopic gynecological surgery or not, in Korean women. Methods and Methods: 277 of 302 women who underwent gynecological laparoscopic surgery in Severance hospital, between January, 1998 and November, 2000, were enrolled in this study. They were analyzed by chart review. Obesity was defined as BMI(Body mass index) ≥25. Then, they were categorized by BMI[weight(㎏)/height2(㎡)], obese group[BMI≥25(n=74)], and non-obese group[BMI<25(n=203)]. Thereafter, each group was further divided into three groups according to the operation grade. Comparison of patient characteristics and operation parameters between obese group and non-obese group in three sub-groups was made. Results: No significant difference in patient characteristics(age, parity, menopausal status, medico-surgical illness, and history of previous intra-abdominal surgery) between the two groups, except in the distribution of operation grade and adhesion grade, was noted. However, the adhesion grade was evenly distributed in each operation grade group. Then, comparison between two groups was done in each operation grade group. In all operation grade group, no significant difference in operative parameters[estimated blood loss(EBL), operation time, operative complications, post-operative complications, hospital days, and rate of conversion to laparotomy] was found between the two groups. Conclusion: Obesity has been generally known to increase risk in laparoscopic surgery. But, from our study with Korean women, obesity did not seem to increase the risk and gynecological laparoscopic surgery was safely and also feasibly performed in obese women, therefore, it should not be considered as a risk-increasing warning sign.
