Roux-en-Y Gastric Bypass

Laparoscopic Roux-en-Y Gastric Bypass

The Roux-en-Y gastric bypass is the most common weight-loss surgery in the United States and has been utilized in various forms since the 1960’s. It is a major abdominal surgery involving permanent anatomic rearrangement of the gastrointestinal tract and is usually performed laparoscopically. The gastric bypass causes weight loss by limiting the amount of food one can eat (restriction) and by reducing the amount of food that is absorbed by the intestines (malabsorption). Additionally, hormonal changes may help reduce appetite and improve blood sugar regulation.

Advantages:

  • Patients typically see the most weight loss, often 50-80% excess weight loss long-term.
  • There is often significant improvement of many weight-related medical problems, especially type II diabetes due to the powerful hormonal effects of the surgery.
  • Very low mortality rate — below 0.5%.

Disadvantages:

  • Leaks from staple lines could occur resulting in infection or death.
  • Staple line strictures could occur resulting in obstruction and vomiting.
  • Internal hernias and bowel obstructions could occur causing abdominal pain and vomiting.
  • There is a risk of developing marginal ulcers which could cause pain or bleeding, and NSAID (e.g. ibuprofen) pain medication should be avoided.
  • There is an increased risk of nutritional deficiency and a need for more aggressive nutritional supplementation and monitoring due to the intestinal rearrangement.
