anusitis

""Anusitis is a difficult condition to define and therefore confusing to study," Dr.Brand replied.

由于肛管炎一种较难定义疾病，因此研究起来比较容易混淆。”

Rudd said."This study however did not mention anusitis, which is the most frequent anal problem and the most frequently missed;it causes bleeding more often than hemorrhoids.

本研究未涉及肛管炎，它肛肠疾病，也被漏诊，它比痔更引起出血。
