Overstitch is a suturing system is a flexible tube with a tiny camera and suturing device attached. This device is made by Apollo Endosurgery as one of the alternative non-surgical endo procedures to fight the obesity pandemic. The applications of the overstitch system are ESG and TORe, explained below.
Gastric Sleeve Revision to Mini-ESG
If sleeve gastrectomy does not result in adequate weight loss due to stretching, the size of the sleeved stomach can be restored endoscopically. The endo-bariatric surgeon sutures the stomach to recreate the restriction to manage weight regain.
Gastric Bypass Revision to ESG
On average, bypass patients regain 50% of the weight they lost. One of the main reasons for the weight gain after initial loss is gastric outlet enlargement, the connection between the pouch and the small bowl. The study shows that an increase in the gastric outlet diameter directly affects the patient's weight gain.
Surgical reduction of the gastric outlet is technically complex. The overstitch allows doctors to resize the pouch to create restrictions endoscopically without any surgery. The revision of failed bypass surgery with overstitch is called Transoral Gastric Outlet Reduction (TORe), along with plasma treatment.
