비비만 환자와 비만 환자에서 루와이 위우회술 후 체중과 혈청지질 농도의 변화 비교

초록

Background: This study was aimed to investigate the effects of bariatric surgery in non-obese patients through the comparison of the changes in body weight (BW) and serum lipid profile between non-obese and obese patients after Roux-en-Y gastric bypass. Methods: In this study, 116 patients who received laparoscopic Roux-en-Y gastric bypass due to early gastric cancer were included. Patients were divided into two groups, non-obese group (N=76), defined as body mass index <25 kg/m2, and obese group (N=40), body mass index ≥25 kg/m2. BW and serum lipid profile before surgery and at 3, 6, 9, and 12 months after surgery were examined. Results: In all groups, BW and triglyceride (TG) showed significant (P<0.05) decrease after surgery, while high-density lipoprotein cholesterol (HDL-C) showed a significant increase during the first 3 months after surgery, in obese group. Total cholesterol and low-density lipoprotein cholesterol (LDL-C) decreased. However, the effect was significant for only a limited time period after surgery. Mean percentages of BW loss and TG decrease were greater in the obese group after surgery, however, the change was significant for only a limited time period after surgery. Mean percentage of HDL-C increase in non-obese group was greater but was not statistically significant. There were no differences in mean percentages of total cholesterol and LDL-C decrease between the two groups. Conclusion: At 12 months after surgery, all groups showed significant improvement in BW and serum lipid profile. However, mean percentages in BW loss, TG decrease, and HDL-C increase between the two groups were different.
