ManoScan HRM

Indications & Risks

Indications

  •  The ManoScan system obtains a high resolution mapping of pressure levels within tubular organs of the human gastrointestinal tract including the anus/rectum
  • The system is used in a clinical setting to acquire pressures, impedance levels and video, store the corresponding data, and to provide visualization and analytic tools
  • The real-time data and analysis information can be viewed by a physician for diagnostic and analytic purposes

Contraindications

  • Patients with known anal strictures or obstructions preventing insertion of the instrument

Procedure Risks

Patients with previous rectal surgery, bowel inflammation, or bowel obstruction may have a higher risk for iatrogenic bowel perforation.  Three reported cases of iatrogenic perforations after water perfused manometry testing for recto-anal sensory testing are in the literature.  Measurement of maximum tolerable volume via manometry balloon should be performed with caution in patients with restorative proctectomy for rectal cancer or rectal prolapse (Cho et al, 2008;Park et al, 2007).
 
Medical, endoscopic, or surgical intervention may be necessary to address any of these complications, should they occur.  The system is not compatible for use in an MRI magnetic field. 
 
This information should not be used as a substitute for medical advice concerning specific diagnosis and treatment.
