Colonic Slow Transit in Patients with Dyssynergic Defecation and Effectiveness of Biofeedback Therapy

Background: Colonic transit is delayed in two-thirds of patients with dyssynergic defecation. As a result, it's possible that dyssynergic defecation and slow transit constipation are linked. There is a scarcity of research on the coexistence of dyssynergic defecation and slow transit constipation, as well as the efficacy of biofeedback therapy in this group of patients. Methods: The results of anorectal manometry and MR defecography were used to make the diagnosis of dyssynergic defecation. The colon transit time was measured with the help of 24 specially marked markers. All of the patients were given biofeedback therapy. Results: The average age of the 17 patients with dyssynergic defecation in the study was 45.6 years. The colon transit time was prolonged in seven patients (41.2%). In anorectal manometry, 7 patients (41.2%) had improved dyssynergic defecation after dyssynergic defecation. When the relationship between colon transit time and biofeedback therapy was investigated, it was discovered that normal colon transit time was found in 85.7 percent of those who benefited from biofeedback therapy, while slow transit constipation was found in 60% of those who did not. Conclusion: In patients with pre- biofeedback therapy and dyssynergic defecation, colon transit time should be evaluated, and it should be kept in mind that these patients may be resistant to treatment in the case of accompanying slow transit constipation.
