anusitis

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

由于肛管炎是一种难定义的疾病，因此研究起来易混淆。”

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，它是最见的肛肠疾病，也是最被漏诊的，它引起出血。
