Dyssynergia
Conditions
Brief summary
Constipation is a common disorder and current treatments are unsatisfactory. Biofeedback may help patients with constipation and dyssynergic defecation, but its efficacy is unproven and whether this is due to behavioral modification or excessive attention is unknown. Methods: In a prospective randomized trial, the investigators investigated the efficacy of Biofeedback (manometric- assisted anal relaxation, muscle coordination and simulated defecation training), with either sham feedback therapy (Sham) or standard therapy (diet, exercise, laxatives; Standard) in 77 subjects (69 women) with dyssynergic defecation. Primary outcome measures included presence of dyssynergia, balloon expulsion time, number of complete spontaneous bowel movements (CSBM), and global bowel satisfaction. Data analyzed per protocol.

Inclusion criteria
Patients were included if they fulfilled Rome II criteria for functional constipation, and during attempted defecation demonstrated a dyssynergic pattern of defecation, and either had prolonged difficulty with expelling a simulated stool (\> 1 minute) or prolonged delay (\> 20% marker retention) in colonic transit.
Exclusion criteria
They were required to have no evidence of structural or metabolic diseases that could cause constipation, as assessed by colonoscopy/barium enema and routine hematological, biochemical and thyroid function tests. Patients taking drugs known to be constipating, for example opioids were either excluded or were asked to discontinue the drug prior to enrollment. Other
