Rectal sensation, tone, and compliance test (ie, response to graded balloon distention)
CPT4 code
Name of the Procedure:
Rectal Sensation, Tone, and Compliance Test (i.e., response to graded balloon distention)
Summary
The Rectal Sensation, Tone, and Compliance Test is a diagnostic procedure that evaluates how your rectum responds to different levels of pressure using a small balloon. The test helps doctors understand issues related to bowel movements and rectal function.
Purpose
The procedure is used to diagnose conditions affecting bowel control and rectal function, such as chronic constipation or fecal incontinence. The goal is to identify abnormalities in rectal sensation (feeling), muscle tone, and elasticity, which can help guide appropriate treatment.
Indications
This test is indicated for patients experiencing:
- Chronic constipation
- Fecal incontinence
- Incomplete bowel movements
- Unexplained rectal pain
Patients who have symptoms suggestive of an underlying rectal dysfunction, despite normal findings on other diagnostic tests, are also good candidates for this procedure.
Preparation
- Patients may need to follow a clear liquid diet for 24 hours before the test.
- A bowel cleansing regimen (laxatives or enemas) might be required the night before the procedure.
- Inform your doctor about any medications or existing health conditions.
Procedure Description
- The patient lies on their side.
- A small, deflated balloon attached to a thin tube is gently inserted into the rectum.
- The balloon is gradually inflated with air or water to specific pressures while the patient's sensations and responses are monitored.
- Measurements of rectal sensation, muscle tone, and compliance are recorded.
- The balloon is then deflated and removed.
Tools used include:
- A specialized balloon catheter.
- A device to control and measure inflation pressures.
Anesthesia or sedation is usually not required, but local anesthetic gel may be applied.
Duration
The procedure typically takes about 30 to 60 minutes.
Setting
This test is performed in a hospital or outpatient clinic equipped for specialized diagnostic procedures.
Personnel
- The procedure is usually conducted by a gastroenterologist or a specially trained nurse.
- A technician or assistant may be present to operate equipment and record data.
Risks and Complications
Common risks:
- Mild discomfort or pressure
- Minor bleeding or irritation in the rectal area
Rare risks:
- Rectal perforation
- Infection
Complications are generally managed with conservative treatments, such as rest and antibiotics, if necessary.
Benefits
- Provides valuable information on rectal function.
- Helps identify the cause of bowel control issues.
- Informs effective treatment plans. The benefits are typically realized soon after the results are analyzed and a treatment plan is initiated.
Recovery
- Patients can usually return to normal activities immediately after the test.
- Any mild discomfort can usually be managed with over-the-counter pain relief.
- Follow-up appointments may be scheduled to discuss results and treatment options.
Alternatives
- Colonoscopy
- Manometry studies (anal and colonic)
- Imaging studies (e.g., MRI, CT scan) These alternatives may be less specific in evaluating rectal function but involve different risks and benefits.
Patient Experience
During the procedure, patients might feel:
- Pressure or fullness as the balloon inflates
- Mild discomfort, akin to the feeling of needing to have a bowel movement
After the procedure, patients may:
- Experience slight spotting or irritation
- Usually have minimal, if any, pain
Pain management and comfort are prioritized, ensuring the patient is as comfortable as possible during and after the test.
