Operative (30-day) mortality for gastric bypass when performed by skilled surgeons is about 0.5%. The risk of dying in the first month after a Roux-en-Y gastric bypass from complications of the operation is about 0.2-0.5% in expert centers. Studies have demonstrated that the mortality reported by hospitals with less experience with the procedure is far higher than that reported by expert centers. Compared with open procedures, laparoscopic gastric bypass has a higher rate of intra-abdominal complications, whereas the duration of hospitalization is shorter, wound complications are lower, and the postoperative patient comfort is higher.

Lifelong oral or intramuscular vitamin B12 supplementation and iron, vitamin B, folate, and calcium supplementation are recommended to avoid specific nutrient deficiency conditions, such as anemia.

Early complications of the adjustable gastric band procedure are as follows:

  • Injury of the stomach or esophagus
  • Bleeding
  • Food intolerance (most common immediate postoperative complication)
  • Wound infection
  • Pneumonia
