A new surgical tool now allows surgeons to reduce the size of the stomach pouch and stoma through the patient's mouth without making external cuts into the body. Before the ROSE incisionless procedure, patients who regained weight after gastric bypass generally had few treatment options. Scarring and adhesions related to the initial bypass make open or laparoscopic revision surgery very challenging.
The ROSE procedure is performed using a four-channel tube and special incisionless surgery tools. The surgeon advances a flexible tube and a small endoscope through the patient's mouth, into the stomach pouch. The surgeon will then insert the surgical tools through the channels of the tube. Tissue anchors are used to create multiple tissue folds around the stoma reducing the diameter. The surgeon will then use the same technique to place anchors in the stomach pouch to reduce its volume.
