The general risks of surgery, and of rapid weight loss apply to this operation just like the Adjustable Gastric Band.
Specific risks of the operation include:
Leakage from the gastric staple line in 1.0 %, Postoperative bleeding in 0.5 – 1% of cases, Stricture (tight scar in the stomach tube) in 2%.
These risks are higher when the surgery is done in patients who have had previous gastric operations, or have a BMI greater than 50 kg/m2.
Long term risks & side effects include:
Vomiting in 20%, Gastro-Oesophageal reflux in 30%, Anaemia, Vitamin D deficiency, Inadequate weight loss or late weight re-gain can occur.
As this is quite a new operation, the results are limited to follow-up of up to 8 years. This makes it difficult to be certain of the long-term outcomes.
