Yes, you have heard us here! Here, we brief you about this condition. Obstructive defecation syndrome (ODS) can be termed as the inability to pass stool through the digestive tract out of the rectum.
Here, we explain to you the difference between obstructive defecation syndrome and constipation.
Decoding the connection between Obstructive defecation syndrome and constipation
Tons of research suggests that obstructive defecation syndrome (ODS) is one of the main causes of primary constipation. Constipation has a high prevalence in the general population and is a cause for significant morbidity. The ones who have the problem of chronic constipation may be at the risk of obstructed defecation. Constipation caused owing to the obstructed defecation is of two basic types:
Below are the symptoms of obstructive defecation syndrome
Are you aware? The most common symptom of obstructive defecation is the feeling of more stools remaining in the rectum after attempting to pass stool. Furthermore, the other symptoms may include:
- straining to empty
- passing hard stools
- excessive or prolonged straining while passing stool
- routine usage of laxatives or enemas
- prolonged or unsuccessful efforts to evacuate a motion
- long hours spent in the bathroom
- a sensation of incomplete emptying or difficulty wiping clean
- According to a study published the Indian Journal of Radiology and Imaging in 2015, various modalities have been used for the evaluation of ODS.These include fluoroscopic defecography and MRD. MRD can be performed in open magnets in a sitting position or closed tunnel magnets in a supine position. The MRD is performed, and no prior colon preparation is necessary.
- Three hundred milliliters of ultrasound jelly is instilled in the patient's rectum using the rectal tube in the left lateral decubitus position. The patient is then made to lie down in the supine position on the MR machine gantry and imaging is performed using an 8-channel pelvic phased-array coil. All patients undergo colonoscopy before the MRD to exclude other colonic pathologies like colon neoplasms and polyps.
