Fissure of the Anus and Fistula in Ano

A concise clinical manual treats two rectal disorders in separate parts: the first defines anal fissure (irritable ulcer), reviews anorectal anatomy and nerve supply, and outlines typical symptoms, physical and digital examination, differential diagnosis, prognosis, and both palliative and operative management; the second surveys fistula in ano, discussing frequency, etiology, classification, symptomatology, examination, prognosis, and approaches to conservative and surgical treatment. The author stresses hygiene, the need for prompt and thorough local examination to prevent misdiagnosis, and practical surgical guidance aimed at reliable patient relief.
