Internal hemorrhoids are serious and mainly treated by surgery, which includes hemorrhoidectomy and anastomotic hemorrhoidal mucosal circumferential resection, and the appropriate surgical method should be chosen according to the condition. 1. Hemorrhoidectomy: It is suitable for the treatment of second, third and fourth stage internal hemorrhoids. During the operation, the patient will take the lateral position or truncal position, and after local anesthesia, the anus will be expanded to 4-6 fingers first, so as to make the hemorrhoids exposed, and separate the hemorrhoids, and excise the hemorrhoidal nucleus. Surgery will cause local trauma, need a certain amount of recovery time. 2. anastomosis hemorrhoidal mucosal circumferential resection: for three, four stages of internal hemorrhoids, also suitable for drug treatment is not ideal for the second stage of internal hemorrhoids patients, the operation is characterized by a short operating time, on the local damage is small, postoperative recovery, but the cost is expensive. During the surgery, the anus is first dilated, and the rectal mucosa is looped and sutured at about 4cm above the dentate line, then the PPH anastomosis is inserted into the anus, and the prolapsed mucous membrane band is excised after the suture is tied and the anastomosis is struck to achieve the therapeutic purpose. Once serious symptoms of internal hemorrhoids are detected, they should be treated actively, and regular medication change and rechecking should be performed as prescribed by the doctor after surgery, so as not to affect the postoperative recovery.
