The Heresy of Hypoabsorptive Bariatric Surgery: A Critical Reappraisal of Long-Term Outcomes and Clinical Trade-Offs

1

Hypoabsorptive bariatric surgery offers superior weight loss and metabolic comorbidity resolution but constitutes less than 3% of bariatric operations in the US.
2

Contemporary evidence suggests hypoabsorptive procedures have short-term risk profiles comparable to established operations when adjusted for baseline characteristics.
3

Long-term studies show that complications from hypoabsorptive surgery accumulate progressively, particularly in frail patients with higher comorbidity.
4

Diabetes remission rates are high after hypoabsorptive procedures, with 92.8% for duodenal switch and 85.7% for single anastomosis duodeno-ileal bypass.
5

Nutritional complications after bariatric surgery increase over time, with 74% of patients experiencing issues by 30 years post-operation.
