ManoScan HRM

Indications & Risks

Indications

  • The ManoScan system obtains a high resolution mapping of pressure levels and, optionally, impedance levels within tubular organs of the human gastrointestinal tract including the esophagus from the pharyngeal region to the stomach and the proximal gut (stomach/duodenum)
  •  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 an inability to tolerate nasal intubation
  • Patients with significant bleeding disorders for whom nasal intubation is contraindicated
  • Patients with a known esophageal obstruction preventing passage of the instrument

Procedure Risks

The risks of catheter insertion into the nasal passage include: discomfort, nasal pain, minor bleeding, runny nose, throat discomfort, irregular heartbeat with dizziness and perforation. In rare instances, the catheter may be misdirected into the trachea causing coughing or choking, or the catheter may shift up or down causing false results.
 
Some medications such as pain medicines, sedatives, antispasmotics, promotility agents and others, can alter normal contraction of the esophagus and therefore may need to be temporarily discontinued to avoid false results.1    As with all procedures, physicians should review a patient’s current medication regime prior to administering this procedure.
 
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 risk information should not be used as a substitute for medical advice concerning specific diagnosis and treatment.
