We detected heavy infections of Blastocystis hominis in four individuals with intestinal obstruction due to cancerous growths. After surgery, the infections spontaneously resolved, without specific chemotherapy. It appears that the B. hominis infection was coincidental and not related to the neoplastic growth. We suggest that intestinal obstruction and concomitant stool retention, plus hemorrhage from cancerous lesions, may have permitted the more abundant growth of B. hominis. This is the first report of a possible relationship between intestinal obstruction and a concomitant B. hominis infection.
我们在四名因癌性生长导致肠梗阻的患者中检测到了人芽囊原虫的重度感染。手术后，感染自行消退，未进行特异性化疗。看来人芽囊原虫感染是巧合，与肿瘤生长无关。我们认为，肠梗阻及随之而来的粪便潴留，加上癌性病变出血，可能使人芽囊原虫生长更为旺盛。这是关于肠梗阻与人芽囊原虫伴随感染之间可能存在关联的首次报告。
