Metabolic and Bariatric Surgery Outcomes in Extreme Age and BMI Groups

IBC Oxford Oral Abstract 60 - Metabolic and bariatric surgery in age and BMI extremes

View Full Paper

Why the study?

Does sleeve gastrectomy compared to Roux-en-Y gastric bypass affect total weight loss and complication rates in patients at extremes of age and BMI?

Population

2,482 patients who underwent metabolic and bariatric surgery between 2019 and 2023, grouped by age and BMI

Comparison

Sleeve gastrectomy (n=745) vs Roux-en-Y gastric bypass (n=1737)

Design

Cohort

Follow-up

up to 24 months

Key result

Surgery type did not significantly affect complication rates, but RYGB patients with BMI <40 achieved significantly higher total weight loss than those who underwent SG.

Overview

RYGB may yield greater weight loss than SG in BMI <40 without excess complications; leaves open need for randomized confirmation at age/BMI extremes.

Key Points

  • Assess the effectiveness and complications of metabolic and bariatric surgery by age and BMI categories.
  • Conducted a retrospective cohort study of 2482 patients between 2019 and 2023.
  • Grouped patients by age (<30, 30-60, >60 years) and BMI (<40, 40-50, >50 kg/m²).
  • Evaluated total weight loss and surgical complications at multiple follow-up points.
  • No significant difference in total weight loss between SG and RYGB in younger patients.
  • SG patients with BMI <40 had lower total weight loss compared to RYGB.
  • Complication rates were similar across elderly patients and those with BMI >50 for both surgeries.

Structured PICO

Does sleeve gastrectomy compared to Roux-en-Y gastric bypass affect total weight loss and complication rates in patients at extremes of age and BMI?

Population
2,482 patients who underwent metabolic and bariatric surgery between 2019 and 2023, grouped by age (<30, 30–60, >60 years) and BMI (<40, 40–50, >50 kg/m²)
I
Intervention
Sleeve gastrectomy (n=745)
C
Comparator
Roux-en-Y gastric bypass (n=1737)
O
Outcome
Total weight loss (TWL) ≥ 20% at 6, 12, 18, and 24 months, and surgical complicationssurrogate

In patients at extremes of age and BMI, sleeve gastrectomy has similar complication rates to Roux-en-Y gastric bypass, though RYGB yields greater weight loss in patients with lower BMI.
