Clinical characteristics of patients with chronic constipation after radical hysterectomy or delivery]

This study was aimed to analyze the clinical characteristics of patients who developed constipation after radical hysterectomy or delivery and to investigate the results of biofeedback therapy for these patients.Thirty-five chronic constipation patients with radical hysterectomy (radical hysterectomy group), 27 chronic constipation patients with delivery (delivery group) and 27 constipation patients with no history of hysterectomy or delivery (control group) were included. Clinical characteristics of these patients, including the results of biofeedback therapy, were analyzed.The delivery group showed higher rates of pelvic floor dyssynergia than the control group (14/27, 52% vs. 6/27, 22%; p<0.05). The prevalence of slow transit constipation was lower in the radical hysterectomy group and delivery group than in the control group (7/35, 20% and 5/27, 19% vs. 12/27, 44%; p<0.05). The prevalence of anatomical abnormalities was not different between the groups. The radical hysterectomy group showed higher rate of obstructive sensation and the delivery group showed higher rate of hard stool and digital maneuvers. The biofeedback therapy was effective in 10 out of 12 patients (91%) among the radical hysterectomy and delivery group.Radical hysterectomy and delivery seem to induce functional constipation, which may be caused by anorectal dysfunction such as pelvic floor dyssynergia. The biofeedback treatment was effective in functional constipation after radical hysterectomy or delivery.
