How long it takes for the edema to subside after hemorrhoid surgery has to be judged in context and varies from person to person, and no specific time can be determined. Edema at the anal verge after hemorrhoid surgery is a common complication after mixed hemorrhoid surgery, and its causes are multifaceted, related to surgical factors, local infection, pain, constipation and other factors. Most of the patients’ edema can subside with conservative treatment, mostly in 2-3 weeks, while some edema does not subside completely and may require trimming treatment. The usual surgical treatment options for hemorrhoids are external peel and ligation and TST surgery. The swelling usually goes down quickly after PPH and TST and can be discharged without any special conditions. In addition, patients with hemorrhoids need to pay attention to perianal hygiene and wash promptly after defecation to prevent contamination of the trauma. It is also important to pay attention to diet, eat more fruits and vegetables to prevent constipation, and eat a semi-liquid diet that is easy to digest. It is recommended to develop good bowel habits and control the duration of each bowel movement to no more than 5 minutes.
