Background

Recent clinical studies have suggested sleeve gastrectomy is the most performed effective treatment modality for severe obesity. However, long-term data after sleeve gastrectomy has not been investigated for super-obesity in Korea.ObjectivesThis study aims to evaluate the long-term effects of sleeve gastrectomy in super-obese populations in Asian populations

Methods

We retrospectively reviewed patients who underwent sleeve gastrectomy from 2007 to 2022. We evaluated long-term (>= 60 months) outcomes.

Results

42 patients who underwent sleeve gastrectomy from 2007 to 2022 were included. The mean age at the time of surgery was 32.57 +- 3.79 years. The mean weight was 137.44 +- 15.15 kg and the mean body mass index (BMI) was 49.22 +- 2.66 kg/m2 preoperatively. The BMI in the postoperative first, third, fifth and seventh year was 31.40 +- 3.77, 31.89 +- 3.40, 35.39 +- 3.30, and 30.12 +- 1.77, respectively. The percentage of total weight loss in the postoperative first, third, fifth and seventh year was 36.36 +- 6.29, 35.28 +- 5.72, 27.78 +- 8.99, and 40.17 +- 6.49, respectively. There was no 30-day peri-operative mortality. The complication rates within 30 days were 4.76% including 1 bleeding and 1 wound infection.

Conclusions

These findings show that sleeve gastrectomy is a safe and effective long-term bariatric-metabolic surgery option for super-obesity in Korea. Randomized prospective control studies between sleeve gastrectomy or Roux-en-Y gastric bypass are needed to confirm the long-term bariatric-metabolic effects and safety
