There are many postoperative complications of mixed hemorrhoids, and different complications can occur depending on the surgical method. Generally, the most common complications exist as follows; 1. Postoperative bleeding is a more serious complication, and postoperative bleeding is generally divided into two types, primary bleeding and secondary bleeding. The so-called primary bleeding is bleeding within 24 hours after surgery, and bleeding again after 24 hours is called secondary bleeding. Early bleeding also has many causes and is closely related to the surgery itself, so for postoperative bleeding, the treatment should be decided according to the amount of bleeding. If the bleeding is very little can be compressed to stop the bleeding, if the bleeding is much must go to the operating room and then treated separately for another surgery, otherwise there will be more serious adverse consequences; 2, pain, postoperative pain for sure, but there are light and heavy, depending on the surgical method, the severity of hemorrhoids and the degree of patient tolerance are closely related. The pain is lighter and can be handled, but there are many ways to deal with the heavier pain, such as the application of long-acting anesthetics during and after surgery, as well as postoperative anesthetic pumps, pain medications, Chinese herbal auricular pressure beans, acupuncture points, acupuncture, acupuncture, etc.; 3, urination difficulties, there are several reasons for urination difficulties, such as postoperative wound filling many dressings to compress the urethra can not be discharged, postoperative wound pain leads to sphincter spasm caused by urination difficulties and anesthesia The difficulty in urination after the operation is caused by anesthesia. There are also other reasons, such as too much fluid, combined with prostate enlargement, etc. Therefore, difficulty in urination is also the most common complication of mixed hemorrhoids after surgery, and there are many ways to deal with it, such as hot compresses, acupuncture, and if that doesn’t work, a urinary catheter can be inserted. Many post-operative patients do not go to surgery because they are afraid to insert a urinary catheter and are afraid of post-operative pain; 4. Post-operative anal stenosis is a serious post-operative complication, as too many hemorrhoids are removed from the hemorrhoid nucleus after surgery and too much skin is removed from the perianal area after the wound heals, resulting in anal stenosis. So anal stenosis is also a common complication, but it is a late complication. There are also many ways to deal with anal stenosis, such as anal dilation, medication, and reoperation; 5. Other complications such as wound edema and non-healing wounds.
