In general, between 10% and 30% of patients having any type of weight loss surgery will end up needing later surgery to treat complications or weight regain. One of the main ways to avoid this is to attend regular follow-up appointments to ensure that behaviours, strategies and good eating choices remain on track.
Revisional surgery for bariatric patients can be needed, whether the patient has had a Band, a Sleeve or a Bypass. Redo or revisional surgery is always more complicated than the initial surgery because of obvious changes to the organs with scar tissue present. It often requires further investigation and consultation with the patient.
