    Abstract:
    The development of peptic ulcers in gastric tubes used for esophageal reconstruction for cancer are rare. However, they can potentially cause serious complications, including perforation and hemorrhaging. We experienced a case in which an ulcer of large size developed in the gastric tube, and it was very difficult to treat. The patient was a 72-year-old man, who had undergone an esophagotomy of the thoracic portion, an gastroesophagoplasty through the anterior portion of the sternum, and postoperative radiotherapy 2 years ago. Eight days after his admission, the ulcer began excessive bleeding, and we performed an emergency operation. The ulcer perforated into the mediastinum, and developed an abscess involving the intrathoracic artery. After hemostasis and debridement, we resected the upper half of the gastric tube, closed the oral side of the remaining portion, and converted the cervical esophageal stump into an external fistula. The wound was covered with a flap. A histological examination showed an ulcer with no evidence of malignancy, and without any signs of healing. Five months were required for the wound to heal completely. After that, we succeeded in reconstruction through jejunal free-transfer, using the microvascular surgery technique. Some pathogenesis is suggested for gastric ulcers after gastroesophagoplasty. Despite performing a vagotomy, the secretion of acid from the gastric mucosa is common. Both this condition, and the deterioration of the mucosal barrier caused by surgery, can play significant roles in the development of the ulcer. The histological influence of postoperative radiotherapy is also important, as this treatment aggravates the circulatory disturbance, and disturbs the histological reaction necessary for healing.
