Spastic hypertrophy of the puborectalis muscle, clinically known as puborectalis syndrome, is often accompanied by reflex contraction and loss of diastolic function of the muscle, causing abnormal physical conditions. Puborectal muscle syndrome is thought to be associated with infection, constipation, and prolonged use of laxatives. Inflammation of the puborectalis muscle causes spasms, which cause further irritation during defecation, and aggravation of pain, causing abnormal contraction of the puborectalis muscle, which leads to edema, fibrosis, and scarring of the muscle, resulting in hypertrophy and loss of diastolic function, and resulting in the development of the corresponding disease. Puborectal muscle syndrome can cause difficulty in defecation and prolonged defecation time, which can be detected through clinical examination and defecography. Early stage of the disease can be cared for through dietary modification and warm water bath, etc. Conservative treatment is ineffective and some of the patients need surgical treatment (cutting off part of the puborectalis muscle), and the specific treatment plan needs to be standardized under the guidance of the clinician. If you feel unwell, you should go to the hospital in time, and under the guidance of the physician, give targeted treatment after clarifying the cause.
