Vagus nerve blocking therapy (morbid obesity); laparoscopic implantation of neurostimulator electrode array, anterior and posterior vagal trunks adjacent to esophagogastric junction (EGJ), with implantation of pulse generator, includes programming

Vagus nerve blocking (VBLOC) therapy is a medical procedure designed to assist in the treatment of morbid obesity. This therapy targets the vagus nerve, also known as the pneumogastric nerve or cranial nerve X, which originates from the brainstem. The vagus nerve consists of two branches that extend along the esophagus, bronchi, and major blood vessels, passing through the diaphragm and terminating in the upper part of the stomach. It plays a crucial role in the regulation of hunger and satiety by transmitting signals between the stomach, pancreas, and brain. In VBLOC therapy, a specialized technique is employed where an intermittent, high-frequency, low-energy electrical stimulus is applied to block these nerve impulses. This interruption in communication is intended to help manage feelings of hunger and promote weight loss. The procedure involves laparoscopic implantation of a neurostimulator electrode array around the anterior and posterior vagal trunks, located adjacent to the esophagogastric junction (EGJ). This minimally invasive approach includes the implantation of a pulse generator, which is programmed to deliver the electrical stimulation necessary for the therapy to be effective.
