title: Robotic-assisted Heller myotomy versus laparoscopic Heller myotomy for the treatment of esophageal achalasia: a case-control study.
abstract: Minimally invasive surgery has become the gold standard for the treatment of achalasia. The incorporation of robotic technology can improve many limitations of laparoscopic surgery, through, for example, the availability of three-dimensional vision, increasing the degrees of movement, avoiding the fulcrum effect and optimizing ergonomics. The aim of this study was to compare robotic-assisted laparoscopic Heller myotomy (RAHM) with laparoscopic Heller myotomy (LHM) in terms of efficacy and safety. Thirty-one patients with diagnosis of achalasia confirmed by esophagogram and manometry were included. Dysphagia and weight loss were the main complaints in both groups. 18 patients were treated with LHM and 13 patients with RAHM. There was no difference in mean operative time (76 ± 13 vs. 79 ± 20 min; P = 0.73). Intraoperative complications were less frequent in the robotic-assisted procedures (5.5% vs. 0%); however, this was a non-significant difference. 94.5-100% of patients had relief of their symptoms. We conclude that RAHM is a safe and effective procedure. The operative time is no longer than in LHM, but it is necessary to evaluate the technique in randomized clinical trials to determine its advantages in terms of intraoperative complications.
