[Proctalgia Fugax--what's new over the last 100 years?].

Proctalgia Fugax is a benign, self-limiting disease characterized by episodes of intense pain in the anorectal area occurring at infrequent intervals. It is common, but most suffers do not seek medical advice. Although its classical symptomatology was describe more than a century ago, the etiology is unclear. Theories regarding the etiology have centered on alteration in the internal anal sphincter function and morphology. For most patients after gathering a detailed history, reassurance and warm baths will suffice. In persistent cases therapies that induce internal anal sphincter relaxation are the main treatment modalities.
