Gastric bypass operation for obesity
World Journal of Surgery
|August 26, 1998
Summary
Gastric bypass surgery is a highly effective obesity treatment, evolving from ulcer procedures. It leads to significant weight loss and resolves obesity-related health issues with low risks.
Area of Science:
- Bariatric Surgery
- Metabolic Surgery
- Obesity Management
Background:
- Gastric bypass evolved from peptic ulcer disease treatments.
- First described in 1967, it has undergone significant modifications.
- Currently exists as a hybrid surgical procedure.
Purpose of the Study:
- To present the evolution, modifications, risks, and outcomes of gastric bypass.
- To discuss future trends in gastric bypass for obesity treatment.
- To highlight the Fobi pouch operation, a specific gastric bypass modification.
Main Methods:
- Review of historical data and modifications of gastric bypass.
- Evaluation of surgical outcomes, including morbidity and weight loss.
- Analysis of co-morbidity resolution and metabolic consequences.
Main Results:
- Gastric bypass is a gold standard for obesity treatment.
- Perioperative morbidity is less than 10%.
- Average excess weight loss is 70%, with an 85% success rate (≥50% excess weight loss at 2 years).
- Obesity-related co-morbidities are typically ameliorated.
- Metabolic deficiencies are manageable with supplements.
Conclusions:
- Gastric bypass is a safe and effective bariatric procedure.
- Significant weight loss and co-morbidity improvement are achieved.
- Controllable metabolic deficiencies and favorable long-term outcomes support its use.
