Note 21 — Chapter II · SYMPTOMATOLOGY—PHYSICAL EXPLORATION—DIAGNOSIS—PROGNOSIS.

In some cases of fissure the irritable condition of the sphincter will cause such contraction of the anus when an examination is attempted that it will be impossible for the surgeon to pass his finger into the rectum without etherization of the patient. In these instances it is best to advise the patient to submit to such operative measures as may be deemed necessary at the same time that the examination is made under ether.
