What Is an Anorectal Balloon Catheter?
An anorectal balloon catheter is a single-use medical device used during Balloon Expulsion Testing (BET) and other anorectal physiology assessments to evaluate rectal muscle function and bowel evacuation. It helps healthcare professionals assess patients with chronic constipation, pelvic floor dysfunction, and suspected anorectal disorders by providing objective information about anorectal function.
Unlike imaging tests that primarily identify structural problems, an anorectal balloon catheter helps evaluate how the rectum and pelvic floor muscles work together during defecation. This functional information can support clinical decision-making when interpreted alongside patient history, physical examination, and tests such as anorectal manometry.
Why Is Balloon Expulsion Testing Important?
Patients with chronic constipation or difficulty emptying the bowels may have different underlying causes. Some have slow-transit constipation, while others have disorders affecting pelvic floor muscle coordination.
A Balloon Expulsion Test (BET) helps clinicians evaluate rectal evacuation by inserting a balloon catheter into the rectum, inflating it according to the manufacturer's Instructions for Use, and asking the patient to expel it. The results are interpreted together with other clinical findings to help guide diagnosis and treatment planning.
Common Clinical Applications
Healthcare professionals may use an anorectal balloon catheter for:
- Balloon Expulsion Testing (BET)
- Evaluation of chronic constipation
- Assessment of pelvic floor dysfunction
- Functional defecation disorder evaluation
- Anorectal physiology testing
- Biofeedback assessment with compatible systems
- Gastrointestinal motility studies
Benefits of an Anorectal Balloon Catheter
Key advantages include:
- Supports standardized anorectal physiology testing
- Provides objective functional assessment
- Minimally invasive and generally well tolerated
- Single-use design to support infection prevention protocols
- Compatible with selected biofeedback and physiology testing systems
- Helps clinicians develop evidence-informed treatment plans
Why Healthcare Professionals Trust This Diagnostic Approach
Professional organizations recognize anorectal physiology testing as an important part of evaluating selected patients with chronic constipation and suspected defecatory disorders.
The American Gastroenterological Association (AGA) and the American Society of Colon and Rectal Surgeons (ASCRS) include Balloon Expulsion Testing and anorectal physiology testing within their clinical guidance for appropriate patients. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) also provides evidence-based educational information on constipation and digestive disorders.
