Abstract

Esophageal diverticulum is a rare problem on clinical medicine because it does not cause any symptoms. But we have had five cases of esophageal carcinoma arising from diverticulum. We studied clinical features, endoscopic diagnosis and treatment for these cases seen at our hospital. The subjects consisted of three men and two women with average age of 68.8. The locations of diverticula were as follows ; one case at cervical esophagus, two cases at middle thoracic esophagus, one case at between middle and lower thoracic esophagus and another one at lower esophagus. All cancers were superficial types in endoscopic gross classification. Esophagectomy was performed for three cases, diverticulectomy with irradiation was performed for one and only irradiation was performed for another one. Pathologically, all resected specimens showed squamous cell carcinoma. Three cases performed esophagectomy are alive free from recurrence. In other two cases, esophageal cancer had recurred. One received diverticulectomy with irradiation died after five years and four months of operation. Another one received only irradiation is alive with local recurrence. We studied clinicopathological findings, diagnostic features and treatment about esophageal carcinoma arising from deverticulum reported in Japan.
