Comparing bariatric surgery and medical therapy for obese adolescents with type 2 diabetes

Background: Mounting evidence in recent years has demonstrated that the number of obese adolescents has continued to rise. Obese adolescents are more likely to be diagnosed with type 2 diabetes, which causes additional harm. This study aimed to compare the clinical outcomes of bariatric surgery and medical treatment. Methods: We conducted a multicenter, nonrandomized, retrospective study on 202 obese adolescents with type 2 diabetes who received surgery or medical treatment in three hospitals from 2017 to 2019. We analyzed the effects of surgery and medical treatment in terms of weight loss, glycemic control and the remission of type 2 diabetes. Propensity score matching was conducted to balance the confounding factors.Results: Among the 202 adolescents, 109 adolescents underwent surgery, and the remaining 93 adolescents received nonsurgical treatment. Both in the entire cohort and in the propensity-score matching cohort, the mean body mass index (BMI) and total weight in the surgery group notably decreased. Similarly, the effect of surgery on glycemic control (with respect to HBG, HbA1c, HOMA-IR) was superior to that of medical treatment. In the surgery group, the remission rate of diabetes was 76.1% in the entire cohort and 80.5% in the matched group, which was significantly higher than that in the control group (6.5% and 5.7%, respectively). In addition, LRYGB had better effects on weight loss and glycemic control than LSG. Conclusion: Bariatric surgery is more effective in the control of weight loss and type 2 diabetes than medical treatment. The effects between different types of bariatric surgeries remain to be further investigated, and longer follow-up times are needed.(c) 2022 Asian Surgical Association and Taiwan Robotic Surgery Association.

Automated summary

This study aimed to compare the clinical outcomes of bariatric surgery and medical treatment for obese adolescents with type 2 diabetes. The results showed that bariatric surgery was more effective than medical treatment in controlling weight loss and type 2 diabetes, with LRYGB surgery having better effects on weight loss and glycemic control.
