The anismus, or failure in the phenomenon of somatic sphincter relaxation device that allows a bowel movement, has been implicated as the principal factor in the problem of obstructed defecation. Current diagnostic methods, which rely on laboratory physiological measures during attempted defecation and proctography complex dynamics, have become essential for diagnosis. With the use of a computerized outpatient novel method for registration of the sphincter function with the patient at home, we report a 80% reduction in our rate of diagnostic anism which suggests that conventional tests fail to accurately diagnose this condition, probably because they represent a very poor natural physiology of defecation. The treatment of this disabling condition is more complex and a variety of surgical procedures and drug have failed. In these patients the retraining of the ano-rectal function biorectroalimentación has been very successful and is the preferred modality of management.
Impossibility of relaxation of the sphincter apparatus of the anus during defecation, has been implicated as a major factor in the problem of constipation. Current methods of diagnosing anism depends on laboratory tests, the dynamic proctographie, review the most complex, has been, until now, the most conclusive review. With the use of a computerized ambulatory record, we found a 80% reduction in our rates of diagnosis, which suggests that conventional tests do not make a correct diagnosis, probably because they do not adequately consider the natural physiology of defecation. The treatment of this entity is complex and alarmingly many pharmacological or surgical methods have failed. By cons, biofeedback and anorectal training are often successful and represent the therapeutic method of choice.
