“…Proton pump inhibitors are the mainstay for treatment of acid disorders such as GERD in humans. 25 However, Nissen fundoplication is the gold standard for GERD treatment in patients that require antireflux surgery: 1) patients with symptoms who respond inadequately to proton-pump inhibitors (PPI); 2) patients that continue to have nonacid reflux, even eliminating heartburn by PPI; 3) patients with symptoms such as chest pain, cough, or wheezing, who have well-documented reflux events; 4) patients with secondary peptic stricture, Barrett's esophagus, or vocal cord injuries; and 5) patients with well-documented GERD, who wish to stop the chronic use of a PPI. 26 In humans, Nissen fundoplication can be performed laparoscopically with five access ports, two of which are 10 mm in length and three that have a 5 mm span.…”
