Abstract
Two cases of superficial carcinoma in the middle esophageal(parabronchia1)diverticulum and the other one in the Tower esophageal(epiphrenic)diverticulum are reported.The case l was a 54-year-old female who was pointed out to have a superficial carcinomaof type O-IIa in the middle esophageal(parabronchial)diverticulum on the right side. Thecarcinoma was considered to invade into the submucosal Layer. Therefor, total thoracicephagectorny through a right posterolateral thoracotomy and a median laparotomy wascarried out. in additon, adjuvant chemotherapy was performed. The case 2 was a 74-year-old female who was pointed out to have a superficial carcinoma of type O-I in the loweresophageal(epiphrenic)diverticulum, who was treated with radiation therapy before. Onthis admission, recurrence of type O-IIc lesion was noted. Therefor, lower thoracicesophageal and cardial resection through a left thoracotomy and a median laparotomy wascarried out. The occurrence of carcinoma arising in an esophageal diverticulum is rare.We reported the problems of endoscopic diagnosis and treatment.
