Two cases of esophageal diverticula.

Two cases of pharyngoesophageal diverticula were reported with reference to previous studies. Definite diagnosis was established by esophagography. The surgical treatment is generally conducted in accordance with Goodman-Parnes' criteria for surgical indication. We also carried out surgery on the basis of this criteria. One-stage diverticulectomy was performed and favorable results with no postoperative complications were obtained.
