[Anorectal pull-through and vector volume manometry].

Anorectal manometry has been developed from an object of clinic oriented scientific interest to an established tool within the spectrum of proctologic diagnostics. At present it represents the only objective diagnostic method with regards to continence disorders; it is routinely applied in the evaluation of constipation, of incontinence, of pre- and postoperative conditions in diseases of the anorectum as well as in the indication and therapeutic control investigations during biofeedback training of the anal sphincter. The new technique of determination of the anal sphincter pressure vector volume allows for the most sensitive functional separation of patients with different degrees of continence; this method delivers a 3-dimensional graphic imaging of the sphincter pressure profile, thus allowing for an objective visualisation of the present mechanic defect and an aid in planning a surgical correction.
