1/37. Massive tracheal necrosis due to compression by an innominate artery aneurysm associated with a grade IV Chagasic megaesophagus and chronic duodenal ulcer.

    A 49-year-old man suffered necrosis of the cephalad tracheal segment due to compression by an innominate artery aneurysm. A peritracheal abscess, a grade IV chagasic megaesophagus, and a duodenal ulcer were also present. The patient underwent a three-stage surgical treatment, and 7 years later he is doing well, and breathing and eating normally.

2/37. Spontaneous closure of a large tracheal fistula due to descending necrotizing mediastinitis.

    We present a case of a 77-year-old man who had a large tracheal fistula due to descending necrotizing mediastinitis. He underwent long-term care with a respirator after mediastinal drainage operations. The fistula was covered spontaneously with the anterior wall of the esophagus 1.5 months postoperatively.

3/37. Transmural necrosis of the esophagus secondary to acute aortic dissection.

    A case of transmural ischemic necrosis of the esophagus secondary to aortic dissection is presented. A 66-year-old woman with acute type A aortic dissection underwent total arch replacement with a technique of deep hypothermic arrest and retrograde cerebral perfusion. Postoperatively she had hematemesis, and endoscopic examination revealed circumferential mucosal necrosis and desquamation of the lower esophagus. She died of multiple organ failure on postoperative day 74. autopsy demonstrated transmural necrosis of the esophagus secondary to ischemia. ischemia of the esophagus secondary to aortic dissection is extremely rare.

4/37. Black esophagus: a view in the dark.

    A 73-year-old man had a low anterior resection for a villous adenoma in the rectosigmoid. On the 4th day after surgery, he suddenly developed severe interscapular pain. Aortic dissection was ruled out, but endoscopy showed black mucosa of the entire esophagus. With conservative treatment, including proton pump inhibition, he recovered completely. We hypothesize that a transient gastric outlet obstruction and massive gastroesophageal reflux played a significant role in the etiology of this rare and alarming, but, in this case, completely reversible, syndrome.

5/37. Redoing reconstruction of the esophagus using remnants of the ileo-left colon aided by microvascular anastomosis.

    Theoretically, the jejunum, fasciocutaneous or myocutaneous flap is recommended as an esophageal substitute in redoing reconstruction of the esophagus after a second incidence of corrosive injury. However, other esophageal substitutes should also be considered. We present a case of a 42-year-old woman who underwent esophageal reconstruction using an ileocolon graft for corrosive esophageal stricture ten years before. The patient ingested caustic drain cleaner again and underwent resection of the ileocolon graft secondary to corrosive necrosis. Two and a half months after the second incidence of corrosive injury, reconstruction of the esophagus was again performed using a graft of remnant ileo-left colon aided by microvascular anastomosis. The patient was able to swallow a regular diet after the procedure. Remnant ileo-left colon is a good alternative esophageal substitute in cases of repeated corrosive injury.

6/37. Black esophagus: should it be considered an unfavorable prognostic factor?

    Black esophagus is a rare condition, reported for the first time in 1990. It is always noted in severely compromised patients. The diagnosis is possible using endoscopy. An esophageal ischemic injury should be considered. It is important that a differential diagnosis is made with consideration of other necrotic conditions of the esophagus. Only supportive treatment and the improvement of the associated disease appear possible.

7/37. Acute necrotizing esophagitis: a case report.

    Acute necrotizing esophagitis is rare. The exact etiology is unknown in most cases. The esophagus appears black, necrotic and ulcerated on the upper endoscopy, thus the term "black esophagus" is used. Histologically, there is necrosis of the esophageal mucosa and submucosa. Here, we present a patient with cholangiocarcinoma who had upper gastrointestinal bleeding and was found to have acute necrotizing esophagitis on the upper endoscopy.

8/37. Sarcoma of the thyroid gland: a case report.

    Sarcoma of the thyroid gland is a very uncommon malignant tumor (<1% of thyroid cancers) characterized by severe local course and rapid metastatic dissemination and very poor prognosis. We report the case of an 84-year-old woman hospitalized for expiratory dyspnea, severe malnutrition and swallowing disorders leading to bronchial infection. She had a voluminous (20 cm) extra-thoracic right-neck goiter with a considerable superficial venous pattern that had developed on an old goiter before growing recently. CEA and calcitonin levels were normal. The cervical-thoracic CT demonstrated a partially necrosed heterogeneously hypodense tumor compressing the esophagus and the trachea with displacement of adjacent structures which were not directly invaded. Large areas of necrosis and a probable metastatic image measuring 3 cm in the right median pulmonary lobe were observed. Macrobiopsy disclosed grade 3 sarcoma. Complete resection delivered a 3.170 kg tumor. histology confirmed the diagnosis of sarcoma without neoplastic extension. Apart from right recurrent palsy, the initial post-operative period was satisfactory and the patient was discharged. Four and a half months later she was rehospitalized with local recurrence with a large metastatis in the right lung. She died two weeks later.

9/37. Black esophagus induced by severe vomiting in a healthy young man.

    Black esophagus is an uncommon entity that has been described only a few times previously. It is defined as a dark pigmentation of the esophagus associated with histologic mucosal necrosis. Most cases have no known etiology, although ischemia, nasogastric tube trauma, infection, gastric outlet obstruction, gastric volvulus, and hypersensitivity to antibiotics have all been suggested as possible causes. Herein we report the case of a young, healthy, athletic man who developed black esophagus due to severe vomiting after alcohol overindulgence and summarize the other published cases to date.

10/37. carcinosarcoma of the stomach.

    In the gastrointestinal tract, carcinosarcomas are most frequently seen in the esophagus. carcinosarcoma in the stomach is a rare tumor. We report a carcinosarcoma of the antrum of stomach. The tumor was polypoid and exophytic in appearance and located in the antrum. Immunohistochemical studies showed positivity for cytokeratin, epithelial membrane antigen and cytoplasmic carcinoembryonic antigen in the epithelial component. Positive staining with vimentin, desmin and focal smooth muscle actin and negative staining with chromogranin were observed in spindle cells. Nuclear positive staining was observed with p53 and Ki-67 in both glandular and spindle atypical cells.
