Anorectal manometry is an exam performed on patients with various complaints in the anal or pelvic floor area. Performed quickly and usually painless, the procedure helps in the detection and differentiation of various diseases, and helps the indication of the best treatment for each case.

There is still some embarrassment in people when it comes to seeking help when they realize that something is wrong with their anal region. But in order for the problem to be properly diagnosed and the treatment to start as soon as possible, it is essential to consult a physician and perform the requested tests.

Anorectal manometry procedure

Anorectal manometry is a simple, fast, and usually painless procedure. It is done without the need for sedation, fasting or other specific preparations, and there is no need for an escort during the exam. The specialist introduces a type of malleable straw into the patient’s anus. It is required that the patient perform movements of contraction, evacuation effort and relaxation, for example, so that the sensors record the pressure variations, which correspond to the muscular strength of the region. Tests may also be performed to assess sensitivity and rectal ability.

The probe used in the exam has a balloon at its end and transmits the information collected to the manometer (equipment used to measure pressures). These signals allow the assessment of the anus pressure at rest, contraction and during evacuation movements – in addition to reflexes and the sensitivity of the region. These parameters are essential for understanding the physiology of evacuation and finding the best solution for each problem.

At COLONO, we use solid state probes, which do not require the use of water and thus produce minimal discomfort compared to traditional infusion equipment. The exam lasts for about 15 minutes. Because it is a test that requires active patient participation, no sedation is used. The patient performing anorectal manometry may return to normal activities soon after the exam.

Indications

Anorectal manometry is very important so that the specialist can diagnose anorectal and pelvic floor diseases as well as indicate an appropriate treatment. On suspicion of incontinence, this exam is very important, because it makes it possible to evaluate the strength of the muscles of the region and its coordination.
These are some of the symptoms that indicate the need for investigation of this kind:

  • Fecal incontinence
  • Anal pain for no apparent reason
  • Constipation (difficulty in evacuating)
  • Suspicion of idiopathic or chagasic megacolon (dilatations of the large intestine and rectum that may be related to Chagas disease)
  • Evaluation of patients before and after radiotherapy in the region, as may be the case in the treatment of tumors of the cervix or the prostate
  • Hemorrhoids Disease
  • Anal fissures
  • Anal fistulas

In addition, anorectal manometry is also required as a preoperative exam for surgeries that may involve the anus and rectum, such as hemorrhoid surgeries, anal fistulas, and anal fissures, as well as those involving the rectum.
Anorectal manometry is a safe and fundamental procedure for an appropriate treatment for each case.
