[Surgically treated Zenker diverticulum: a double-contrast radiologic study and videorecording]. / Diverticoli di Zenker operati: studio radiologico a doppio contrasto associato a video-registrazione.

Sixteen patients who had undergone the surgical resection of pharyngoesophageal diverticula were investigated with combined double-contrast radiology and video-recording. In 11 patients morphological or functional anomalies were identified. The authors report their results and stress the high incidence of postoperative stenoses (18%) and recurrences (43%). The combined use of double-contrast examination and video-recording is suggested to detect such functional disorders as those which were identified in 68% of the patients in this series of cases.
