Biofeedback provides long-term benefit for patients with intractable, slow and normal transit constipation

Area of Science:

• Gastroenterology
• Colorectal Surgery
• Pelvic Floor Rehabilitation

Background:

• Idiopathic constipation often resists conventional medical treatments, necessitating alternative therapies.
• Biofeedback therapy is a proposed alternative, but its long-term efficacy and patient selection criteria remain unclear.
• Traditional biofeedback treatment has been limited to patients with normal colonic transit and impaired pelvic floor coordination.

Purpose of the Study:

• To evaluate the long-term efficacy and outcomes of biofeedback treatment for idiopathic constipation.
• To identify patient subgroups that benefit from biofeedback therapy.

Main Methods:

• A retrospective analysis of 100 patients who completed biofeedback over 12 months prior.
• Collation of pretreatment data on bowel function, symptoms, whole gut transit time, and anorectal physiological testing.
• Long-term follow-up via structured interviews to assess treatment outcomes.

Main Results:

• At a median follow-up of 23 months, 55% found biofeedback helpful, and 57% reported improved constipation.
• Significant reductions were observed in straining, abdominal pain, bloating, and oral laxative use.
• Patients with slow or normal transit, and those with or without paradoxical pelvic floor contraction, benefited equally; anorectal testing did not predict outcomes.

Conclusions:

• Biofeedback is an effective long-term treatment for most patients with idiopathic constipation refractory to traditional therapies.
• Pelvic floor abnormalities and transit time should not be used as exclusion criteria for biofeedback treatment.
