Adenocarcinoma is an uncommon gastrointestinal malignancy. Fiberoptic duodenoscopy is the diagnostic procedure of choice, allowing direct visualization as well as biopsy of the neoplasm. Conversely, in the vast majority of cases, CT is unable to demonstrate the duodenal tumor. We describe a technical procedure that has permitted CT visualization of a small ampullary tumor in two cases.
Superior mesenteric artery syndrome is an uncommon clinical condition. A case of duodenal vascular compression and a review of the literature are reported in order to clarify the pathophysiology of the disease. Diagnostic values of hypotonic duodenography and angiography are emphasized. Although, the significance of long-term pH monitoring and gastric emptying for preoperative study and its importance in follow-up after the surgical treatment are evaluated.

The Authors describe a rare case of esophageal stenosis complicated by gastroesophageal reflux due to Trichosporon beigelii in the absence of a pathologic predisposition or immunodeficiency. The diagnosis was drawn by embedding membrane fragments obtained endoscopically in Sabouraud and blood-Agar cultures. The patient was treated with antimicotics, immunostimulants, inhibitors of the gastric protonic pump, prokinetics and later underwent endoscopic dilatation combined with Savary-Guillard and pneumatic dilatators of growing diameter, until complete "restitutio ad integrum" of the esophageal lumen.
