Value of dynamic defecography in patients with the spastic pelvic floor syndrome

Objective: To evaluate the role of dynamic defecography in diagnosis patients with the Spastic Pelvic floor syndrome. Materials and methods: The images of defecography in 44 cases of anismus and 22 volunteers were retrospectively analyzed. Methods: The anorectal angle(ARA) at quiescent and defecation, and the difference between them was calculated. T test was used in statistical analysis. Results: 21 patients with spastic pelvic floor syndrome(SPFS) also suffered from rectocele, anterior mucosal prolapse or other disease. The ARA in patients group at quiescent, defecation and difference between them were (103.2 ± 8.62)°, (92.8 ± 7.38)° and (10.4 ± 7.9)° respectively, and those in normal control group were (117.4 ± 12.7)°, (137.1 ± 10.4)° and (19.7 ± 12.4)° respectively. There was significant difference in ARA between two groups (P < 0.01). Conclusion: Dynamic defecography can provide reliable diagnostic basis for the Spastic Pelvic Floor syndrome. (authors)
