What is revisional weight loss surgery?

Revisional weight loss surgery can mean many things. It may refer to someone who is having one type of weight loss surgery then switches to another. For example, lap band to sleeve or sleeve to gastric bypass. 
 
There are also endoscopic revisional procedures. Revisional surgery is usually higher risk than the original procedure due to increased scarring on the inside of the stomach.
With the growing popularity of weight-loss surgery, there is greater need for revisional surgery to alter or repair one of the many types of surgical procedures for the treatment of morbid obesity.

The most common reason patients undergo gastric bypass revision is weight-related. Either not enough weight was lost following surgery, or too much was gained back. In some cases, there are medical complications that require revisional surgery.

Your surgeon will want to rule out diet or exercise problems before undertaking another procedure. Each revision must be tailored to meet the particular needs of the patient.

Revisional surgery may be an option for patients who have already undergone a procedure and need another one to either repair the first one, or for those who have gained weight or have not lost sufficient weight.

In about 50% of cases, vertical banded gastroplasty, or "stomach stapling" fails, resulting in inadequate weight loss. Staple erosion in more recent cases may cause chronic inflammation, ulcers, and infection. This is one major reason that our surgeon use absorbable sutures instead of staples to perform intestinal attachments to the stomach.

In other cases, a patient's original gastric bypass may become ineffective when the small pouch and opening to the intestine which the surgeon created stretches, allowing more food into the intestine, leading to weight gain. Such stretching of tissue may occur because of overeating, or from the healed tissue stretching naturally.

Sometimes scar tissue develops during the healing process after a first surgery which can make a revision surgery and healing more difficult. Our surgeons have created procedures that lower the risk of a second surgery.

Most often, patients need a revision surgery to convert an older weight-loss procedure to a more modern, effective one, such as the Roux-en-Y gastric bypass with a duodenal switch.
