Objective: Laparoscopic Heller myotomy and Dor fundoplication has become the gold standard in treating esophageal achalasia and robotic surgical platform represents its natural evolution. The objective of our study was to assess durable long-term clinical outcomes in our cohort., Methods and Procedures: Between June 1, 1999 and June 30, 2019, 111 patients underwent minimally invasive treatment for achalasia (96 laparoscopically and 15 robotically). Fifty-two were males. Mean age was 49 years (20 - 96). Esophageal manometry confirmed the diagnosis. Fifty patients underwent pH monitoring study, with pathologic reflux in 18. Preoperative esophageal dilation was performed in 76 patients and 21 patients received botulin injection. Dysphagia was universally present, and mean duration was 96 months (5 - 480)., Results: Median operative time was 144 minutes (90 - 200). One patient required conversion to open approach. Four mucosal perforations occurred in the laparoscopic group and were repaired intraoperatively. Seven patients underwent completion esophageal myotomy and added Dor fundoplication. Upper gastrointestinal series was performed before discharge. Median hospital stay was 39 hours (24 - 312). Median follow up was 157 months (6 - 240), and dysphagia was resolved in 94% of patients. Seven patients required postoperative esophageal dilation., Conclusions: Minimally invasive Heller myotomy and Dor fundoplication are feasible. The operation is challenging, but excellent results hinge on the operative techniques and experience. The high dexterity, three-dimensional view, and the ergonomic movements of robotic surgery allow application of all the technical elements, achieving the best durable outcome for the patient. Robotic surgery is the natural evolution of minimally invasive treatment of esophageal achalasia., (© 2022 by SLS, Society of Laparoscopic & Robotic Surgeons.)

Purpose: Laparoscopic fundoplication is now a cornerstone in the treatment of gastro-esophageal reflux disease (GERD) with sliding hernia. The best outcomes are achieved in those patients who have some response to medical treatment compared to those who do not. Robotic fundoplication is considered a novel approach in treating GERD with large paraesophageal hiatal hernias. Our goal was to examine the feasibility of this technique., Methods: Seventy patients (23 males and 47 females) with mean age 64 y old (22-92), preoperatively diagnosed with a large paraesophageal hiatal hernia, were treated with a robotic approach. Biosynthetic tissue absorbable mesh was applied for hiatal closure reinforcement. Fifty-eight patients underwent total fundoplication, 11 patients had partial fundoplication, and one patient had a Collis-Nissen fundoplication for acquired short esophagus., Results: All procedures were completed robotically, without laparoscopic or open conversion. Mean operative time was 223 min (180-360). Mean length of stay was 38 h (24-96). Median follow-up was 29 mo (7-51). Moderate postoperative dysphagia was noted in eight patients, all of which resolved after 3 mo without esophageal dilation. No mesh-related complications were detected. There were six hernia recurrences. Four patients were treated with redo-robotic fundoplication, and two were treated medically., Conclusions: The success of robotic fundoplication depends on adhering to a few important technical principles. In our experience, the robotic surgical treatment of gastroesophageal reflux disease with large paraesophageal hernias may afford the surgeon increased dexterity and is feasible with comparable outcomes compared with traditional laparoscopic approaches., Competing Interests: Conflicts of Interest: The authors declare no conflict of interest., (© 2020 by JSLS, Journal of the Society of Laparoscopic & Robotic Surgeons.)

Until recently, pneumatic dilatation and intrasphincteric injection of botulinum toxin (Botox) have been used as initial treatments for achalasia, with myotomy reserved for patients with residual dysphagia. It is unknown, however, whether these nonsurgical treatments affect the performance of a subsequent myotomy. We compared the results of laparoscopic Heller myotomy and Dor fundoplication in 44 patients with achalasia who had been treated with medications (group A, 16 patients), pneumatic dilatation (group B, 18 patients), or botulinum toxin (group C, 10 patients). The last group was further subdivided according to whether there was (C2, 4 patients) or was not (C1, 6 patients) a response to the treatment. Results for groups A, B, C1, and C2, respectively, were: anatomic planes identified at surgery (% of patients)--100%, 89%, 100%, and 25%; esophageal perforation (% of patients)--0%, 5%, 0%, and 50%; hospital stay (hrs)--26+/-8, 38+/-25, 26+/-11, and 72+/-65; and excellent/good results (% of patients)--87%, 95%, 100%, and 50%. These results show that: (1) previous pneumatic dilatation did not affect the results of myotomy; (2) in patients who did not respond to botulinum toxin, the myotomy was technically straightforward and the outcome was excellent; (3) in patients who responded to botulinum toxin, the LES muscle had become fibrotic (perforation occurred more often in this setting, and dysphagia was less predictably improved); and (4) myotomy relieved dysphagia in 91% of patients who had not been treated with botulinum toxin. These data support a strategy of reserving botulinum toxin for patients who are not candidates for pneumatic dilatation or laparoscopic Heller myotomy. [ABSTRACT FROM AUTHOR]
