To avoid this expansion, a calibration ring, such as the MIDCAL ™, may be placed around the stomach. The stomach pouch remaining after gastric bypass is thus calibrated by the ring, and the risks of expansion are greatly reduced. Protecting the gastric reservoir in this way makes it possible to maintain the effect of satiety, and to limit the absorption of an excessive amount of food. Placement of a calibration ring like MIDCAL ™ must be done by a qualified surgeon with experience in weight loss surgery. Ask your surgeon if placement of a MIDCAL™ may be a good indication for you.
