Summary
Obesity surgery guidelines may be too restrictive. This review found that patients with less than 80% excess weight undergoing biliopancreatic diversion experienced comparable complications and results to those with higher excess weight.
Area of Science:
- Bariatric Surgery
- Metabolic and Endocrine Disorders
- Surgical Gastroenterology
Background:
- Classical indications for obesity surgery typically require 100% excess weight or 45 kg.
- Recent studies suggest potential benefits for patients with lower excess weight thresholds.
Purpose of the Study:
- To challenge the traditional indication for obesity surgery based on excess weight.
- To compare complications and outcomes in patients undergoing biliopancreatic diversion with excess weight below 80% versus above 80%.
Main Methods:
- Retrospective review of 170 patients who underwent biliopancreatic diversion.
- Comparison of weight-related complications, reoperations, and results between two groups: excess weight <80% and excess weight >80%.
Main Results:
- Sixty-four out of 170 patients (37.6%) had an excess weight below 80%.
- No significant differences in complications or surgical outcomes were observed between the groups with lower (<80%) and higher (>80%) excess weight.
Conclusions:
- The findings challenge the conventional 100% excess weight indication for obesity surgery.
- Biliopancreatic diversion appears safe and effective for patients with excess weight below 80%, suggesting a broader patient eligibility.
