PURPOSE

The purpose of this study is to evaluate the usefulness of individualized metabolic surgery score for Korean patients in determining bariatric surgical procedures.

MATERIALS AND METHODS

A total of 135 patients with type 2 diabetes mellitus who underwent sleeve gastrectomy (n=19) or Roux-en-Y gastric bypass (n=116) at our institute with a 1-year follow up were analyzed for the predictive power of diabetes remission using the individualized metabolic surgery scoring system.

RESULTS

At the postoperative follow-up of 1 year, the remission of type 2 diabetes mellitus (HbA<6.5%, off medications) was achieved in 88 (65.2%) patients. The remission rates showed no significant differences between patients who underwent sleeve gastrectomy and Roux-en-Y gastric bypass (63.2% versus 65.5%; P=0.84), regardless of the severity of type 2 diabetes mellitus. Although there was no statistically significant difference in the remission rate according to the bariatric surgery procedures (P>0.99 in mild, P=0.11 in moderate, P>0.99 in severe IMS score), remission rates were higher in moderate severity patients who underwent Roux-en-Y gastric bypass than in those who underwent sleeve gastrectomy (69.7% versus 37.5%).

CONCLUSION

The remission rates after bariatric surgery procedures were similar to that of the previously reported study. Despite the limitations of our data, the individualized metabolic surgery score can be used as a complement to other scoring systems in Korean patients.
