MSA: laparoscopic or robotic approach?


 Gastroesophageal reflux disease (GERD)—the pathologic reflux of gastric contents into the distal esophagus—is the most common benign disorder of the esophagus. Its incidence is at 10–20% of the Western population and it yearly cost of treatment in the USA in 9.3 billion dollars. Although first line treatment for the disorder is medical therapy with proton pump inhibitors, an estimated 30–40% of patients will continue to experience medically refractory GERD. In this population anti-reflux surgery can be offered. Traditional anti-reflux surgery is done via the Nissen fundoplication, a technically difficult surgery with uncomfortable side effects of bloating and inability to belch. Magnetic sphincter augmentation (MSA) of the lower esophagus via the LINX device was introduced a less technically challenging alternative to the Nissen. The LINX provides fewer side effects of bloating and inability to belch and has been adapted widely to the practice of anti-reflux surgery. In this paper we discuss the progression of surgical practices with the LINX, including an analysis of the laparoscopic and robotic approaches to MSA device implantation.
