Original Article


Laparoscopic Heller myotomy and Dor fundoplication is considered a safe and effective treatment for achalasia. Robotic-assisted Heller–Dor procedure (RAHD) has emerged as an alternative approach due to improved visualization and fine motor control. The aim of this prospective study was to evaluate clinical, and functional results of RAHD. We evaluated a group of 66 patients with achalasia that underwent robotic-assisted Heller–Dor operation. Before treatment all patients underwent a diagnostic work-up such as upper endoscopy, esophageal barium swallow and high resolution manometry. The presence of postoperative gastroesophageal reflux disease was diagnosed by impedance and pH monitoring (MII-pH). Dysphagia improved in 92.4% of patients after treatment. Barium swallow series showed esophageal emptying in 100% of patients and a significant reduction of the esophageal diameter (p = 0.00235). Forty-five of 66 patients (68.2%) underwent upper endoscopy and 35 of 66 (53%) underwent MII-pH. Esophageal erosions were found in 4/45 (8,8%) and MII-pH showed abnormal results in 3/35 patients (8.6%). RAHD ensures a meticulous esophageal and gastric myotomy, allowing to visualize and divide each muscle fibers with a low rate of intraoperative and postoperative complications. resulting in turn in good clinical outcomes, radiological findings and functional results even if robotic tecnique definitely increases the surgical cost in the treatment of these functional esophageal disorders.
