[Digestive system endoscopy in the elderly and in patients with severe comorbidities]. / Emésztorendszeri endoszkópos vizsgálatok idoskorban és súlyos társbetegségekben.

Besides the technical equipment, the endoscopic team's theoretical and practical skills, the success of endoscopic intervention is influenced by the patient's general condition. Advanced age, severe co-morbidities may increase the risk, especially in case of operative endoscopy. The decision is more complicated when alarm symptoms urge the examination. The endoscopic examination of digestive system, biliary track and pancreas in advanced age can safely be performed as alternatives of surgical intervention. It is important to know the exact stage of cardiovascular and pulmonary diseases, besides, in case of stroke the patient's cooperation is very important. In everyday practice the most common problems are the endoscopic examination of the patient in oral anticoagulant and/or thrombocyte aggregation inhibition therapy and the question of suspending, modifying or restarting the therapy. Examining the patients with implanted electronic device as well as antibiotic prophylaxis in expanding range of indications are special issues. The gastroenterologist makes the decision based on the knowledge of the endoscopic intervention, the patient's risk classification, the indications, the contradictions and the alternative diagnostic possibilities. This review attempts to give an overview with some practical aspects.

[Primary T-cell lymphoma of the small bowel]. / Primer vékonybél T-sejtes lymphoma operált esete.

Primary malignancies in the small intestine are relatively rare. There are no specific methods to find these tumours in early stage. The authors report a case of a primary T-cell lymphoma in the small bowel that caused diagnostic challenges. A 66-year-old woman presenting with abdominal pain and and a palpable mass in the left upper quadrant of her abdomen was admitted into the hospital. Blood tests, endoscopic examinations, ultrasonography and CT scan could not reveal a definitive diagnosis. While a small bowel follow through examination demonstrated an entero-enteral fistula, its exact position could not have been determined. Consequently, an exploratory laparotomy was carried out, and a tumour was found involving the small bowel loops. The involved portion of the small intestine (with the fistula) was resected, and a side-to-side small bowel anastomosis was performed. Histological and immunohistochemical analyses revealed a primary T-cell lymphoma of the small bowel. There was no evidence of metastatic disease at the time of surgery. The patient received adjuvant chemotherapy, but three months later multiple lung metastases were detected. Small bowel malignant tumours cause significant diagnostic difficulties. Therefore, diagnosis and adequate treatment are usually delayed for some weeks. In the future, capsule endoscopy could help in the diagnostic work-up. Nevertheless, surgical exploration and resection of the tumour will be necessary for the correct diagnosis and treatment.
