滴虫多寄生于女性阴道,很少寄生于肠道。由于滴虫性肠炎少见,所以在临床上容易造成误诊。我院曾将1例滴虫性肠炎误诊为急性菌痢而误治多日,现介绍如下: 患者男性,70岁,工人。因解粘液性大便伴左下腹痛2日,于1985年8月31日入院。发病以来,大便每日3～5次,有里急后重感。曾于1984年7月有过类似病史,经用中药治愈。体检无明显阳性体征发现。 Trichomoniasis more parasitic in the female vagina, rarely parasitic in the intestine. Due to rare trichomonas enteritis, it is easy to cause misdiagnosis in clinical. In our hospital, one case of trichomonas enteritis was misdiagnosed as acute bacillary dysentery and was mistakenly treated for many days. The introduction is as follows: Male patient, 70 years old, worker. Mucolytic stool with left lower abdominal pain on the 2nd, on August 31, 1985 admission. Since the onset of stool daily 3 to 5 times, tenesmus heavy sense. Had in July 1984 had a similar medical history, with Chinese medicine cure. No significant positive physical examination found.
