BackgroundThe relatively rare carcinoma of the ampulla of Vater is a neoplasia with a good prognosis compared to pancreatic cancer. Preoperative staging is important in planning the most suitable surgical intervention.AimTo prospectively evaluate the diagnostic accuracy of Endoscopic Ultrasonography (EUS) in comparison with conventional US and CT scan, in staging of patients with ampullary carcinoma.Patients and Methods20 patients (7 women and 13 men) with histologically proven carcinoma of the ampulla of Vater were assessed by EUS, CT scan and US. Results were compared to surgical findings.ResultsEndoscopic biopsies were diagnostic in 76% of the patients. Detection of ampullary cancer with US and CT scan was 15% and 20% respectively. Only indirect signs of the disease were identified in the majority of cases using these methods. Overall accuracy of EUS in detection of ampullary tumours was 100%. The EUS was significantly (p < 0.001) superior than US and CT scan in ampullary carcinoma detection. Tumour size, tumour extension and the existence of metastatic lymph nodes were also identified and EUS proved to be very useful for the preoperative classification both for the T and the N components of the TNM staging of this neoplasia. The diagnostic accuracy for tumour extension (T) was 82% and for detection of metastatic lymph nodes (N) was 71%.ConclusionEUS is more accurate in detecting ampullary cancer than US and CT scan. Tumor extension and locally metastatic lymph nodes are more accurately assessed by means of EUS than with other imaging methods.

Placement of self-expanding metal stents is a safe and cost effective treatment modality that improve the quality of life, as compared with other palliative techniques, for patients with inoperable malignant esophageal obstructions. In cases of expansion of the mass a second stent can be used; however, the overall survival of these patients, is poor.

Background: The aim was to evaluate and validate a bowel disease questionnaire in patients attending an out-patient gastroenterology clinic in Greece.

The present study was designed to determine the frequency of candidal esophagitis in cancer patients with oral thrush. Patients with clinically and microbiologically diagnosed oral candidiasis were evaluated by endoscopy for concurrent esophageal candidiasis. Esophageal involvement was documented by mucosal lesions, microbiological findings of candidal infection in smears of brushing material, positive cultures of brushing material, and histological evidence of mucosal invasion by the yeast. For 21 of the 22 patients studied, there were endoscopic and microbiological findings of candidal esophagitis. Cultures of the brushing material from all 22 patients were positive, while histological evidence was found for 14 patients. Only 10 of the patients had mild esophageal symptoms. It is concluded that oral thrush represents a reliable marker for esophageal candidiasis in patients with cancer. Routine endoscopy is not necessary to confirm the diagnosis; this procedure should be reserved for patients with persistent thrush and symptoms despite antifungal therapy.

The fact that it mostly concerns (relatively) young patients may suggest a potential causative relation between those autoimmune disorders and the early development of atrophic gastritis with hypergastrinaemia, which subsequently leads to the occurrence of gastric carcinoid tumours at a young age.
