Recto-anal motor function test

Rectal-anal motor function measurement An anorectal manometry can be performed on the patient using an electronic air pump and a fluid perfusion digestive tract pressure monitoring system. Basic Information Specialist classification: Digestive examination classification: other examinations Applicable gender: whether men and women apply fasting: fasting Tips: Do not take drugs that stimulate the stomach before checking. Normal value The initial rectal sensation value was 87.3 ml (P<0.05), the rectal defecation value was 128.4 ml (P<0.05), and the rectal pain value was 206.1 ml (P<0.05). Clinical significance Abnormal results In patients with irritable bowel syndrome, the anal internal sphincter resting pressure, the internal sphincter maximum systolic pressure, the minimum volume of rectal anal inhibition, ie the minimum inhibitory volume and rectal compliance, were not significantly different from healthy people, and the rectal initial Feeling sputum, rectal bowel movements and rectal pain are lower than normal. Need to check the population of irritable and comprehensive patients. Precautions Contraindications before the test: Do not take drugs that stimulate the stomach. Taboo when checking: 1. Pay attention to the patient's feelings. 2. Inject gas to pay attention to speed and pressure, and observe the minimum suppression capacity. Inspection process Anorectal manometry was performed with an electronic air pump and a fluid perfusion gastrointestinal pressure monitoring system. First record the anal internal sphincter resting pressure and the internal sphincter maximum systolic pressure sensory function test with increasing pressure phase expansion, inflating into the balloon, the inflation rate is 38ML / s, each pressure increase 5mmHg, the instrument automatically records the gas injection capacity, The time between the two insufflation intervals was reported. The subjects reported the sensation through the sensory language score table to observe the initial rectal sensation of the rectum, rectal defecation and rectal pain, and then calculate the rectal compliance. At the same time, the rectum was able to lead out the rectum during the insufflation. The anal inhibition reflects the minimum volume above the internal sphincter pressure drop, ie the minimum inhibition capacity. Not suitable for the crowd Not suitable for checking the crowd: none.
