The robot can break bars with the best of them: a novel approach to treating cricopharyngeal bars with myotomy.

Introduction: Failure of the cricopharyngeus to relax results in oropharyngeal dysphagia, which over time results in hypertrophy and increased risk for aspiration. Open myotomy is one definitive treatment option, however there are several drawbacks attributable to the long neck incision, ± drain placement, and invasiveness of the procedure. We aim to share our experience using the DaVinci robotic platform to perform a minimally invasive cricopharyngeal myotomy, which has never been described before in the literature.
Methods: All robotic cricopharyngeal myotomies performed in adult patients by a single surgeon from 2021 to 2022 were retrospectively reviewed. No patients were excluded. Outcomes of interest included length of procedure, time to diet resumption, hospital length of stay, complications, symptom improvement at follow-up, and symptom recurrence.
Results: Eight robotic cricopharyngeal myotomies were performed. The median age was 65 years old (62-91) and mostly female (n = 5, 56%) with a median BMI of 28.9 kg/m ² (21.7-39.5). The median procedure length was 113 min (94-141) and there were no intraoperative complications. All patients underwent a post-procedural esophagram with no leaks were identified. All patients were started on clear liquids in recovery and transitioned to full liquids prior to discharge. All but one patient was subsequently discharged home on the same day as procedure. All patients had routine 2-week post-operative follow-up in addition to phone follow-up at a later date (6-11 months post-operative). All patients reported resolution of symptoms. There were no complications or readmissions. No instances of recurrence were reported. On cost analysis, the minimally invasive robotic approach allows for an outpatient procedure with similar cost to an open approach with a one-night stay.
Conclusion: Our experience with the novel technique of minimally invasive robotic cricopharyngeal myotomy for cricopharyngeal bars with cervical dysphagia is safe, efficacious, less invasive, and cost saving, with excellent patient outcomes.
