[Epstein-Barr virus genome positive lymphoepithelioma-like carcinoma of the stomach].

EBV is associated with a high number of tumours and non-tumourous conditions. The rare lymphoepithelioma like carcinoma of the stomach,--just as similar tumours of foregut origin (thymus, lung, salivary gland)--are frequently EBV genom positive with the expression of only a few genes (EBV nuclear antigen 1, EBV encoded ribonucleoproteins/EBER/, latency I). On the basis of the clinicopathological analysis of two cases and literature data the authors point out the male predominance and the relatively favourable prognosis of the patients, furthermore the frequent cardial-subcardial localization of these tumours.

[Changes in the treatment of choledocholithiasis].

Efficacy of nizatidine, clarithromycin and bismuth subcitrate therapy for Helicobacter pylori eradication in duodenal ulcer patients--a preliminary report.

The triple combination of nizatidine, clarithromycin, and bismuth subcitrate resulted in an ulcer healing rate of 98% and an H. pylori eradication rate of 90%. Corresponding 'intention-to-treat' figures were 92% and 84%, respectively.

[Bouveret syndrome diagnosed by endoscopy].

The case of a 74 years old woman suffered from a gallstone disease for 5 years is reported. In the background of the upper abdominal pain and vomiting, which necessitated her hospitalization, a large-size gallstone penetrated into the duodenal bulb and obstructed pyloric channel was found by endoscopic examination. The upper duodenal ileus was verified during the operation, gastroduodenotomy and cholecystectomy were performed, and the 7 x 4 cm size gallstone was removed.
