Surgical treatment of mixed hemorrhoids is a more effective treatment. However, postoperative care of mixed hemorrhoids is also very important. Many patients are prone to edema in the postoperative treatment of mixed hemorrhoids. Let’s take a look at the operation of mixed hemorrhoids. What problems should be paid attention to after edema?
The internal anal sphincter is a part of the rectal muscle ring. When there is high tension, the pressure in the anal canal increases, causing the corresponding venous and lymphatic drainage of the anorectal to be blocked. After mixed hemorrhoids, the internal platysma muscle reflex spasm and the pressure of the anal canal increases, so that the passage of the platysma muscle to the submucous layer of the rectum, the inner layer of the anal canal, the subcutaneous arteries and veins and the corresponding lymphatic drainage are blocked, resulting in the internal anus The gate closing effect of the circulatory muscle has become one of the main reasons for the pain and edema of the anal margin after mixed hemorrhoid surgery.
Anal marginal edema refers to the symptoms of edema, congestion, swelling, swelling, or pain in the anal canal and the skin of the anal margin. It is a common complication after mixed hemorrhoids; during hemorrhoid surgery, the local tissues of the anus are removed, stripped or stitched Damage to the original venous and lymphatic circulation pathways at the wound edge, or poor drainage after surgery, or local inflammatory changes caused by wound infection can cause local circulatory disturbances, increase the osmotic pressure of local blood vessels in the anus, and the physiology of the anus and hemorrhoids. Characteristic, it is very easy to cause local edema in the anus, anal trauma and inflammatory stimulation can cause anal spasm, aggravate pain, block venous and lymphatic drainage, and aggravate anal edema. In addition, squatting on the toilet prematurely after surgery or dry stools, blockage of feces and accumulation in the rectum, oppressing local blood supply, can cause or aggravate edema. Edema of external hemorrhoids is easy to re-form new external hemorrhoids, which affects the effect of surgery and brings mental burden to the patient.
After mixed hemorrhoids, anal margin pain and edema can be removed after part of the inner platysma, the pressure in the anal canal is reduced, but it can still resist the intra-abdominal pressure and maintain anal self-control. The mechanism of radial incision and decompression of the perianal skin of the external hemorrhoid wound is to make the blood and lymph accumulated in the anus part due to the blockage of the circulation channel to be shunted and dredged faster, so that the osmotic pressure of the local tissues and blood vessels is reduced , Is conducive to the re-establishment of the new circulation channel, the local stagnation accumulation is reduced or eliminated, and the edema can be reduced or eliminated.
Whether the postoperative edema care of mixed hemorrhoids is appropriate is of great significance to the therapeutic effect of mixed hemorrhoids.
