The method of excision of external hemorrhoids in the surgery of mixed hemorrhoids, especially cricoid mixed hemorrhoids, whether it is a shuttle or V-shaped incision, is prone to postoperative sequelae such as the formation of new external hemorrhoids due to edema of the preserved flap, anal fissure and anal stenosis due to poor healing of the incision, etc. The use of ∧-shaped flap free fixation instead of the traditional incision avoids the above sequelae and shortens the healing time at the same time. The surgical method of common mixed hemorrhoid is to inject 2ml of 1:1 anti-hemorrhoid injection into the suprahemorrhoidal artery area of mixed hemorrhoids; make incisions from the center of the hemorrhoid nucleus at the dentate line, respectively to the edge of the external part of the hemorrhoid, separate the skin from the hemorrhoid tissue, and make the free flap ∧-shaped; bluntly and sharply peel off the varicose vein mass under the dentate line to 0.3CM above the dentate line, ligate it together with the internal hemorrhoid, remove and preserve 1/3 of the tip; trim the flap that has been Trim the free flap and gently pull the tip of the flap to the root of the ligated hemorrhoid to ensure that the tension of the flap is not too high or too low; use a skin suture to pass one of the ligated threads through the tip of the flap and knot the two ligated threads to fix the flap to the root of the ligated hemorrhoid. The same method is used to treat other mixed hemorrhoids. Surgical method for cricoid mixed hemorrhoids Select 4 to 5 larger hemorrhoids according to their natural demarcation line, and inject 2ml of 1:1 anti-hemorrhoid injection into the suprahemorrhoidal artery area of each of these hemorrhoids, and inject 1:1 anti-hemorrhoid injection into the submucosal and intramucosal layers of the hemorrhoid area of the remaining hemorrhoids, 2 to 4ml for each hemorrhoid, with the total amount of anti-hemorrhoid injection not exceeding 30ml; use the general surgical method for mixed hemorrhoids to The selected 4-5 larger hemorrhoids were ligated and flap fixed, the varicose tissue under the skin flap between the two fixed flaps was excised, and the mucosa was suspended and ligated in the suprahemorrhoidal artery area between the two ligated hemorrhoids, so that the skin incisions were completely closed. After the operation, the pagoda gauze was wrapped with pressure. After surgery, control defecation for 24-72 h. After each defecation and cleaning, insert the hemorrhoid plug with Ma Yinglong into the anus and apply pressure bandage until it heals. Patients with cricoid mixed hemorrhoids should choose the 6 and 12 o’clock position to perform ∧ shaped flap free fixation medially to avoid postoperative fissures and new connective tissue proliferation. Surgical treatment of mixed hemorrhoids is complicated by edema of the incision, secondary bleeding, pain and poor healing during the healing period; in the distant period, it can leave superfluous skin, mucosal ectasia, anal stenosis, defecation disorder and even recurrence. In the author’s opinion, the occurrence of the above symptoms is closely related to the choice of surgical procedure. The traditional V-shaped incision and shuttle incision often cannot remove the varicose tissue below the dentate line completely, which will cause postoperative edema and bleeding of the external hemorrhoid stump, and this is also an important factor leading to postoperative pain; the healing between the residual tissues of external hemorrhoids is slow, plus the skin between the incisions may produce fibrous changes of the incision margins before healing, leading to poor healing of the incisions and the formation of anal fissures. The author has also used other reported incisions, but the results are often unsatisfactory or too complicated. The present procedure maximizes the preservation of skin and mucosa at the dentate line while completely removing the varicose tissue below the dentate line, so the incidence of edema and bleeding is low, and there is little new superfluous skin after surgery. The key to this procedure is whether the skin incision is well aligned and whether the tension of the free fixed flap is suitable, and there is no occurrence of anal fissure, defecation disorder, anal stricture, or mucosal ectasia at follow-up, and the patient’s satisfaction is high.
