Abstract

Background
Bariatric surgery has beneficial effects on weight loss and metabolic profiles in morbidly obese patients. A 12-month retrospective cohort study was performed to investigate changes in body weight according to sex, age, and metabolic parameters among Korean morbidly obese patients after undergoing sleeve gastrectomy.
Methods
We included 58 patients with an initial body mass index (BMI) of 35 kg/m² or more, or a BMI of 30 kg/m² with metabolic comorbidities, who underwent laparoscopic sleeve gastrectomy. We collected body weight and biochemistry data pre- and post-surgery and analyzed longitudinal changes of body weight and metabolic parameters.
Results
The mean preoperative and postoperative weights were 124.77 kg and 92.77 kg (pre- and at 12 months, respectively) in males and 99.21 kg and 75.29 kg in females, respectively (P<0.0001). The mean preoperative and postoperative BMIs were 39.57 kg/m²and 29.39 kg/m² in males, and 38.20 kg/m² and 29.02 kg/m² in females, respectively (P<0.0001). There was no difference in percent (%) BMI change between males and females. However, younger patients aged <40 years showed a higher % BMI change post-op at 2 weeks, 3 months, 6 months, 9 months, and 12 months than those aged ≥40 years. Metabolic parameters were significantly improved after sleeve gastrectomy.
Conclusion
In Korean morbidly obese patients, approximately 25% weight reduction and metabolic improvement were achieved at 12 months after sleeve gastrectomy. Increased percentages of weight change were observed in younger patients. Large-scaled, prospective studies are needed to verify the long-term effectiveness of bariatric surgery in Korean morbidly obese patients.
