Intramural pseudocysts of the upper gastrointestinal tract

Aorto-oesophageal fistula with upper gastrointestinal tract intramural haematoma in an oesophageal cancer patient.

Sudden onset haematemesis occurred in a 52-year old male with oesophageal cancer. Computed tomography showed an aorto-oesophageal fistula with contrast extravasation from the aorta. Thoracic endovascular aortic repair with stent graft was done. The haematemesis stopped postoperatively, but follow-up images (Fig. 1) showed persistent contrast extravasation. The patient died of another episode of...

Upper Gastrointestinal Tract Bleeding : Assessing

Various strategies can be used in the diagnosis of upper gastrointestinal tract bleeding. This study investigates the relevance of anamnestic and clinical findings for the diagnosis of the bleeding source. The authors introduced a computer-aided diagnostic system using Bayes’ theorem and compared it with clinicians’ predictions using anamnestic and clinical findings only. There was no differenc...

Blood Fibrin in Upper Gastrointestinal Tract Obstruction

After high gastrointestinal tract obstruction the blood fibrin increases rapidly. The change is more marked in animals with obstruction of the cardiac end of the stomach. The rise in fibrin parallels closely the toxemia characteristic of such conditions. These results indicate that liver insufficiency cannot be the cause of death in such obstructions.

Oncolytic virotherapy in upper gastrointestinal tract cancers

Upper gastrointestinal tract malignancies are among the most challenging cancers with regard to response to treatment and prognosis. Cancers of the esophagus, stomach, pancreas, liver, and biliary tree have dismal 5-year survival, and very modest improvements in this rate have been made in recent times. Oncolytic viruses are being developed to address these malignancies, with a focus on high sa...
