anusitis

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

由于肛管炎是一种较难定义的疾病，因此究起来比较容易混。”

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.

究未涉及肛管炎，它是最见的肛肠疾病，也是最的，它比痔更引起出血。
