Pharyngeal pouch surgical treatments can be carried out via an endoscopic or open approach. Injection of botulinum toxin into the cricopharyngeus was first described as an alternative treatment to the more invasive surgical procedures performed for cricopharyngeal dysfunction. It has not been previously described as a treatment option for pharyngeal pouch.
To compare operative time, average stay, complication rates and symptom control between endoscopic laser diverticulotomy, botulinum toxin injection and open procedures for pharyngeal pouch patients.
The medical records for 66 pharyngeal pouch procedures, carried out on 47 patients treated between 2011 and 2017, were identified and reviewed.
The mean operative time was 21 minutes for botulinum toxin injection, 38 for endoscopic laser diverticulotomy and 104 for open surgery. The mean hospital stay was 0.6 days for botulinum toxin injection, 4.7 for endoscopic laser diverticulotomy and 4 for open surgery. The improvement in Reflux Symptom Index scores was statistically significant for both endoscopic laser diverticulotomy and botulinum toxin injection. Botulinum toxin injection had a 0 per cent complication rate.
Botulinum toxin injection is a safe and effective treatment for pharyngeal pouch.
