There are more complications after cricoid mixed hemorrhoid surgery, and there are generally no sequelae. Surgery is a kind of trauma regardless of the size, and there are more or less complications after surgery. The complications that generally occur after cricoid mixed hemorrhoid surgery include the following categories: 1. anal pain: related to the size of the incision; 2. anal edge edema: related to the size of the trauma and the lightness of the tension of the skin bridge; 3. anorectal stenosis. The skin of rectal mucosa and anal canal may be more severely damaged during surgery; 4. Urinary retention: partly caused by anesthesia, such as anesthesia blocking the nerves in the pelvis, resulting in weak contraction of bladder smooth muscle, as well as spasm of bladder sphincter, which can cause abnormal defecation; postoperative anal pain can lead to spasm of bladder neck as well as urethral sphincter, plus the postoperative anal canal will be filled with hemostatic gauze and dressings, which can cause pressure on The anal pain can lead to spasm of the bladder neck as well as the urethral sphincter, plus the postoperative anal filling of hemostatic gauze and dressing can cause compression of the urethra, which can lead to urinary retention; 5. anal incontinence: there are few patients who are clinically incontinent because of the circumferential mixed hemorrhoids; 6. longer healing time: the long healing time is mainly due to more incisions and poor drainage; 7. anal swelling: mainly the nerve endings receptors in the residual anal cushion tissue cause persistent stimulation; 8. postoperative bleeding: it is usually the time of defecation When the anal pressure is relatively large, the incision tears or the ligature line falls off prematurely and occurs.
