What happens if anal edema occurs after hemorrhoid surgery?

Anal edema after hemorrhoid surgery may be caused by shallow and concentrated injection of anesthetic drugs, blood and lymphatic obstruction or incomplete treatment leading to blood circulation disorders after surgery, excessive tissue resection or excessive suture tension, postoperative defecation difficulties, wound infection and other factors.

1. The anesthetic injection is too shallow and too concentrated

Local anesthesia is required before hemorrhoid surgery, that is, local anesthetics are injected into the anus. If the local anesthetics are injected too shallowly or too concentrated, the drug solution will remain in the subcutaneous tissue gap and cause anal edema.

2. Blood and lymph return is blocked after surgery

Obstruction of blood and lymphatic return after surgery is also a common cause of anal edema. After hemorrhoid surgery, the anus is compressed by dressings, anal sphincter spasms, sutures or cuts of blood vessels and lymphatic vessels, which hinders blood and lymphatic return, and causes subcutaneous fluid to seep out of the anus, causing edema.

3. Incomplete treatment leads to blood circulation disorders

In mixed hemorrhoid surgery, if only the internal hemorrhoids are partially treated and the external hemorrhoids are not treated at all, or if the annular internal hemorrhoids are ligated without incision decompression, the blood circulation in the anorectum will be obstructed, causing edema.

4. Excessive tissue removal or excessive suture tension

During hemorrhoid surgery, if too much tissue is removed or the suture tension is too high for some reason, it will hinder the return of blood and lymph and promote anal edema symptoms.

5. Difficulty in urination and defecation after surgery

Some hemorrhoid patients are affected by surgery and have difficulty defecating after surgery, which causes them to squat on the toilet for too long, affecting blood return and causing congestive edema.

6. Wound infection

After surgery, if you do not pay attention to postoperative care, the wound may be infected. Once infection occurs, there will be a large amount of exudate, which can easily lead to tissue edema.
