Abstract

In a cohort of 2313 young adults, Roux-en-Y gastric bypass (RYGB) resulted in 3.3% higher total weight loss compared to sleeve gastrectomy (SG) at 3 years post-surgery.

RYGB showed significantly greater percentage total weight loss (%TWL) than SG at 1, 2, and 3 years after surgery.
Females experienced an average %TWL that was 2.75 higher with RYGB compared to SG, while no significant difference was observed in males.
Incidence of complications within 30 days post-surgery did not differ significantly between the two procedures.
Both procedures had similar effects on the progression of obesity-related comorbidities, except for gastroesophageal reflux disease (GERD).
Improvement or resolution of GERD was more prevalent in the RYGB group, with 95.2% showing improvement compared to 56.3% in the SG group.

BACKGROUND: The most commonly performed bariatric procedures worldwide are Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), yet outcomes following these procedures in young adults are limited. Therefore, the objective of this study was to compare weight loss outcomes between RYGB and SG in young adults.

METHODS: This is a nationwide retrospective cohort study of young adults, aged 18-25 years, who underwent RYGB or SG between 2015 and 2019, with data from the Dutch Audit Treatment of Obesity (DATO). The primary outcome was weight loss expressed as percentage total weight loss (%TWL) in a period of 3 years after surgery. Secondary outcomes were the incidence of complications (< 30 days) and progression of obesity-related comorbidities.

RESULTS: In total, 2313 patients were included, 1246 in the RYGB group and 1067 in the SG group. Percentage TWL was significantly higher in the RYGB group compared to the SG group at 1, 2, and 3 years after surgery (respectively 2.4%, 2.9%, and 3.3% higher, p < 0.001). RYGB was associated with an on-average 2.75 higher %TWL compared to SG in females (p < 0.001), although this was not seen in males (β = 0.63, p = 0.514). No differences were found in the incidence of complications, nor the progression of obesity-related comorbidities except for gastroesophageal reflux disease (GERD). There was more improvement or resolution of GERD in the RYGB group (95.2% vs. 56.3%, p < 0.001).

CONCLUSION: Similar numbers of RYGB and SG were performed in young adults, whereas RYGB was associated with greater weight loss in the short- and midterm, particularly in females.
