Noninvasive Procedure for GERD

The SRS system, being developed by Medigus (Omer, Israel), is a specialized flexible endoscope designed to perform an endoluminal partial anterior fundoplication for the treatment of GERD. This eliminates the need for general anesthesia. Fundoplication is a surgical technique used to treat GERD, by strengthening the barrier to acid reflux when the lower esophageal sphincter does not work normally. The surgeon does this by wrapping the stomach around the esophagus to create pressure on the muscle at the opening to the stomach.

The SRS combines a miniaturized video camera, a surgical stapler, and ultrasonic sights for alignment. The distal tip, which measures only 15 mm in diameter, includes all the elements of a standard gastroscope and in addition includes the ultrasound measurement device, the anvil of the stapler, and specialized screws for anchoring the scope while the procedure is performed. A disposable cartridge of staples is inserted into the rigid section of the scope, which is then introduced into the stomach, and the tip is rotated 270º. The cartridge and anvil are aligned using the ultrasonic scope and are joined by two screws that lock the anvil and cartridge together. The staples are then fired. The procedure is repeated to create an antero-lateral wrap, which tapers from 120-180o, and augments the angle of His.

The company has completed pre-clinical animal trials. Since the current standard practice for carrying out a fundoplication procedure is open or minimally-invasive (laparoscopic) surgery, performing a completely noninvasive procedure may revolutionize the treatment of GERD.
