Comparing the Effects of Two Methods of Bariatric Surgery, Laparoscopic Sleeve Gastrectomy and Mini Gastric Bypass, on the Weight Loss of Children and Adolescent Younger Than 19 Years Old: A Three-Year Follow-up Study

There is little data about the surgical outcomes of different procedures in children.

We aimed to compare the difference in three-year surgical outcomes between laparoscopic sleeve gastrectomy laparoscopic sleeve gastrectomy (LSG) and one-anastomosis gastric bypass one-anastomosis gastric bypass (OAGB) in children undergoing these procedures.

A total of 96 children aged ≤ 19 years were listed for bariatric surgery to be included in this prospective study. Demographic characteristics, such as age and gender, and anthropometric indices, including height, weight, body mass index, waist circumference, and hip circumference, as well as postoperative complications, were recorded. The participants underwent LSG and OAGB by the same surgical team. The variables were compared between the groups at baseline and 1, 3, 6, 12, 24, and 36 months after surgery.

At follow-up, the OAGB group had a higher waist circumference after 1 and 3 month(s) (P = 0.011 and 0.005, respectively) and higher hip circumference 3 months after surgery (P = 0.035). Time significantly affected the trend of changes in weight, body mass index, waist circumference, and hip circumference (P < 0.001). There were no cases of postoperative complications.

Our experience showed that LSG had better outcomes after three months, while LSG and OAGB had favorable outcomes on the weight and body mass index (BMI) of children with morbid obesity until three years after surgery.
