A 56 year-old male patient had a gastric resection (Billroth II) at age 33. In 1993 he had vague upper digestive complaints. During investigations for a moderate anaemia biopsies performed during an oesogastroduodenoscopy revealed a jejunitis with Giardia lamblia (G.l.) trophozoites which were also found on the gastric mucosa associated with Helicobacter pylori related chronic active gastritis. The few publications dealing with the presence of Giardia lamblia in the stomach either assert or cast some doubts on the pathogenicity of this protozoa for the gastric mucosa. Gastric involvement by G.l. is usually associated with duodeno-jejunal disease responsible for diarrhoea which may occur as epidemics of varying extension. Since Giardia lamblia infection is not submitted to reporting in Switzerland, the epidemiology in our country is scarcely known and investigated. In our opinion, however, health authorities in Switzerland should consider the need of reporting this infectious disease.
一名56岁男性患者在33岁时接受了胃切除术（毕罗氏Ⅱ式）。1993年，他出现了模糊的上消化道不适症状。在对中度贫血进行检查期间，经食管胃十二指肠镜检查时所取活检显示为空肠炎，伴有蓝氏贾第鞭毛虫滋养体，在胃黏膜上也发现了这种滋养体，同时伴有幽门螺杆菌相关的慢性活动性胃炎。少数关于胃中存在蓝氏贾第鞭毛虫的出版物要么断言这种原生动物对胃黏膜具有致病性，要么对此表示怀疑。蓝氏贾第鞭毛虫累及胃部通常与导致腹泻的十二指肠 - 空肠疾病有关，腹泻可能呈不同程度的流行发生。由于在瑞士蓝氏贾第鞭毛虫感染无需上报，我国对其流行病学情况知之甚少且缺乏研究。然而，我们认为瑞士卫生当局应考虑上报这种传染病的必要性。
