Abstract
PURPOSE: This study was designed to investigate the reliability of thr ee-dimensional vectormanometry for differential diagnosis of fecal inc ontinence. METHODS: Eight-channel, continuous pull-out perfusion manom etry was performed on 23 female patients with traumatic (n = 11) or id iopathic (n = 12) incontinence, respectively. RESULTS: At rest, the mi nimum sector pressure of patients with traumatic incontinence (32 +/- 14 mmHg) was significantly lower than it was in the controls (76 +/- 1 6 mmHg) and in those with idiopathic incontinence (64 +/- 28 mmHg) (P < 0.001). At maximum squeezing, the minimum sector pressure was 57 +/- 22 mmHg in patients with traumatic incontinence and 79 +/- 33 mmHg in those with idiopathic incontinence, both being significantly lower th an in the control group with 152 +/- 27 mmHg (P < 0.001). The asymmetr y index of the patients with a sphincter defect was significantly high er, both at rest (23 +/- 13 percent) and squeeze (26 +/- 12 percent), in comparison with the control group (7 +/- 2 percent at rest and 6.2 +/- 1.6 percent at squeeze) and the patients with idiopathic incontine nce (10 +/- 5 percent at rest and 8.4 +/- 4 percent at squeeze). CONCL USION: Three-dimensional vectormanometry identifies localized pressure deficits in the anal canal, thereby differentiating between sectorial and global sphincter insufficiency.
