Rectoscopy is an exploration that allows the direct visualization of the entire rectum sigmoid, performs a rectal examination and introduces a colonoscope through the anus. Which is a flexible tube with a chamber at its end that allows to evaluate the rectal mucosa.
Complete cleansing of the rectum-sigmoid is necessary, ie it does not contain feces. If this cleaning is not done correctly the study will not be of much value, since the doctor has difficulty visualizing the rectum and can overlook a problem that needs treatment.
For more information, see the Pre-Rectoscope Preparation documentation.
This is a test used to measure the functioning of the esophagus, by placing a thin probe with balls in the final portion. For a esophageal manometry to be conclusive, the patient's collaboration is important.
Reasons for the test
The purpose of esophageal manometry is to see if the esophagus is contracting and relaxing properly.
helps identify causes of chest pain, burning, or difficulty in swallowing or passing food from the mouth to the stomach. It may also be useful for planning some types of surgery or for determining the effectiveness of prior surgery. (Prerequisite for surgery)
- At least 6 hours of fast if it is to be done in the morning, if it is in the afternoon you can have a light breakfast. li>
- The patient can not be sedated during the study because he needs to follow instructions and collaborate with the procedure, and sedation medications affect the outcome of manometry
- If the patient is anti-coagulated (taking or applying medicines to prevent blood from clotting, such as: heparin, Clexane, Warfarin, etc.), you should contact the doctor who does the manometry first
- Bring previous gastroscopy.
- You should stop taking 48 hours before the procedure:
- Prokinetic agents: Metoclopramide (Plasil, Metagliz), Cisapride (Prepulsid), Domperidone (Motilium), Dislep.
- Calcium channel blockers: Nifedipine, Verapamil, Diltiazem, always with permission of the treating physician. If it is by Arterial hypertension do not suspend this medication.
- Anticholinergics: hyoscine, Sintaverin, Buscapine
- Tricyclic antidepressants: Rivotril, etc ...
- Nitrates: Nitroglycerin, Nitroglycerides, Isosorbide Dinitrate, etc. (with doctor's authorization)
- Benzodiazepines: Diazepan (Valium), Midazolam (Dormicum, Domix), Clonazepam, etc ...
After the scan
You may notice slight discomfort in the throat, disappear in a short time.This test has no major complications, and after the scan can eat and perform normal life.
Computerized recto-anal manometry measures the pressure (force) of the anal sphincter muscles at rest, in retentive contraction and if they relax as they should, during defecation. This is the appropriate test to measure rectal anomaly function, it will allow to determine if there are alterations and of what type.
To do this, place a thin probe with holes through the anus. With it you can measure pressures at different levels. The results can help identify some causes of anal pain, fecal incontinence and constipation. It may also be useful for planning some types of surgery or for determining the effectiveness of prior surgery.
What preparation do you require?
DO NOT require fasting, or any other special preparation. An enema is given the night before, and in the morning shortly before the test. The study is painless and safe, so it does not require anesthesia.
After the scan
This test has no complications, and after the scan can perform normal life.
Ph esophageal metastasisPh Metria is a test in which a measurement of the ph or the amount of acid is passed from the stomach to the esophagus for 24 hours. They are used to diagnose and identify the cause of gastroesophageal reflux (heartburn or heartburn). It is mostly indicated in a patient who has failed medical treatment and continues with significant symptoms and may be candidates for surgical treatment. p>
It is also used to assess the efficacy of the treatment that has been indicated to the patient or in patients with rare symptoms such as precordial pain, cough, asthma and other pharyngeal symptoms. p>
how is it done?
The equipment used to perform this test in a small tube that is inserted through the nostril and placed near the lower part of the esophagus. The cable is connected to a small monitor that is inserted in the belt
