ADJUSTABLE GASTRIC BAND
This procedure consists of placing a circular band around the gastric esophagus union, in order to diminish the passage of food. In its inner surface the band has an inflatable pouch that communicates through a subcutaneous reservoir which inflates or deflates the pouch according to the patient’s needs.
History
The gastric band is a purely restrictive technique that doesn’t need any resections and anastomosis of the digestive tract. It had a great boom in England and Australia but its limited long term results have made it obsolete.
