Cricopharyngeal myotomy and excision of a pharyngo-oesophageal diverticulum
It has now been established that Zenker’s diverticula form because of an inability of the cricopharyngeus to open adequately during swallowing. It is thus rational to divide the cricopharyngeus muscle when treating a patient with Zenker’s diverticulum. If the diverticulum is small (less than 2 cm in diameter) nothing further need be done. If the diverticulum is slightly larger (2–4 cm) then the diverticulum is suspended upside down after performing the cricopharyngeal myotomy. If the diverticulum is larger than 4 cm in diameter, it is best to remove it after performing a cricopharyngeal myotomy.
