title: [Persistent pharyngeocutaneous fistula after transcervical resection of a diverticulum of the hypopharynx].
abstract: METHODS
  A 26-year-old white male patient had undergone resection of a diverticulum of the hypopharynx and myotomy of the cricopharyngeal muscle elsewhere. A transcervical approach had been chosen owing to the presence of an arteria lusoria and the associated risk of vessel injury. The patient had subsequently had recurrent fistulas through the skin incision, which had not resolved despite four further operations. He presented in our department with significant weight loss and persistent retrosternal pain. Esophageal manometry revealed that resting muscle tone in the upper esophageal sphincter was still significantly elevated. Assuming that the earlier myotomy had not been completely successful, we decided to complete this operation as revision surgery. The pharynx was closed with a running suture using the Conley technique. The fistula healed, and there were no further recurrences.
  
  
  CONCLUSIONS
  Complete and careful dissection of all muscle fibers back to the mucosa is essential, as well as complete removal of the diverticulum if this operation is to be successful when performed by the transcutaneous approach. Recurrent diverticula are not the only possible complication; persistent pharyngeocutaneous fistulas can also arise.
