Disease relevance of Defecography

MATERIALS AND METHODS: Eleven patients with MS and constipation (10 women, one man) underwent defecography [1].
PURPOSE: To evaluate defecography in assessment of anorectal function in patients with multiple sclerosis (MS) who have intractable constipation [1].

High impact information on Defecography

METHODS: In 190 patients with chronic constipation (age, 53 (range, 18-88) years; 85 percent of whom were women), symptom evaluation, transit time measurement (radiopaque markers), and functional rectoanal evaluation (proctoscopy, anorectal manometry, defecography) were performed [2].
The straining anorectal angle (S-ARA), measured by defecography, improved from a preoperative value of 120.6 degrees +/- 6.9 degrees to a postoperative value of 98.5 degrees +/- 3.5 degrees (P < 0.05), and the perineal descent (PD) improved from a preoperative value of 16.2 +/- 2.5 cm to a postoperative value of 8.1 +/- 1.3 cm (P < 0.05) [3].
Fluoroscopic defecography performed during this procedure in each patient disclosed that the glycerin enema promptly evoked cecal peristalsis, which was transmitted to the distal colon and rectum, and squeezed out almost all the fecal matter, evacuating it from the anus [4].

Gene context of Defecography

Straining anorectal angle (S-ARA) by defecography improved from the preoperative value of 120.6 +/- 6.9 degrees to the postoperative value of 98.5 +/- 3.5 degrees (p < 0.05) and the perineal descent (PD) improved from the preoperative value of 16.2 +/- 2.5 cm to the postoperative value 8.1 +/- 1.3 cm (p < 0.05) [5].
