We present a case of a 52-year-old male patient who died from massive hematemesis as a result of perforation of a benign peptic ulcer into the descending thoracic aorta, 1 year after esophagectomy for esophageal cancer and gastric tube interposition. We also review the literature for mechanisms of ulceration in intrathoracic gastric grafts and for complications of such ulcers.
We present two similar cases of huge distension of the esophageal stump after cervical esophagogastrostomy in two psychotic patients. Chronic use of anti-psychotic drugs, in combination with prolonged mild anastomotic stricture, may have contributed to this situation.
A rare case of a secondary achalasia or pseudoachalasia due to a mesenchymal tumour of the oesophagus is presented. A 67-year-old Caucasian man had symptoms including dysphagia, odynophagia, and weight loss for 8 months. Radiological examination revealed no signs of neoplasia but an exploratory laparotomy revealed the presence of a mesenchymal tumour of the oesophagus. Tucker's criteria constitute an important tool in the differential diagnosis of secondary achalasia from primary achalasia with clinical value, but in this case, exploratory laparotomy rather than non-invasive diagnostic procedures provided the final and definite diagnosis.
A case of delayed rupture of the thoracic aorta into the esophagus after blunt thoracic injury is reported. It involved a hemodynamically stable 18-year-old male patient without any clinical or radiological signs to indicate aortic injury. Aortoesophageal fistula presented in the fifth post traumatic day, with a sudden dyspnea episode, intraperitoneal hemorrhage and lower gastrointestinal bleeding, due to intraperitoneal and intragastric rupture of intramural esophageal hematoma.

18 patients with unilateral staghorn calculi managed by selective hypothermic perfusion are presented and the results reported. The procedure proved to be simple, safe and effective in the management of most staghorn calculi.

Four cases of benign stricture of the oesophagus treated by reversed gastric tube oesophagoplasty are presented. The technique used is described in detail, and the advantages of this method over other ways of bypassing the oesophagus are discussed. The most important advantage is the restoration of normal deglutition with only one extrathoracic anasthomosis.
