Revisional Bariatric Surgery
Obesity and Metabolic SurgeryIf the patient has lost less than 55% of the targeted excess body weight within 18 months after the first bariatric surgery, or if weight gain begins again after the surgery and exceeds acceptable limits, or if long- or late-term complications occur due to the operation, corrective revision surgeries can be performed.
When the need for such a corrective operation arises, what is generally preferred is to convert a failed restrictive surgical procedure into a malabsorptive or combined (restrictive + malabsorptive) method.
Revision surgery after failed gastric banding is generally recommended 3-6 months after band removal. However, if the stomach is in a suitable structure for surgery, revision surgery can be performed in the same session. Here, the thickness of the stomach after the band is removed and the operating environment are important. Although it may vary depending on the patient and the physician, sleeve gastrectomy operations are most frequently performed.
If the patient has undergone sleeve gastrectomy (stomach tube) surgery as the first operation and it is determined that the remaining stomach tissue has expanded during the controls, a procedure called re-sleeving can be applied to narrow the stomach tube. Apart from this, it can also be converted into duodenal switch / pancreaticobiliary diversion surgeries, where the sleeve gastrectomy is the first step.
For example, if serious problems due to reflux develop after sleeve gastrectomy surgery, the surgery can be converted to bypass procedures or reflux-reducing procedures can be applied to the stomach entrance. The procedure can also be changed to bypass in patients with insufficient weight loss.
