Anus drop, also called anus bulge, is a common symptom after anorectal surgery. It is an important reason for patients to fear surgery. It is also a psychological shadow of patients after surgery. It is also an unspeakable pain that patients cannot bear. It is manifested as: consciously falling and discomfort in the anus, or a feeling of blockage and fullness, always wanting to have a bowel movement, but the bowel movement is not smooth, or no stool is discharged, and still feels not pulled clean after going to the toilet, at least 3-4 times a day, or more 7-8 times.
The reasons are as follows:
1. Dressing change stimulation: The sensory nerve endings around the anus are abnormally rich. After being stimulated, they think that there is stool, which will transmit the signal to the brain and make defecation instructions, which will cause the feeling of stool and anal falling. Embolism, oil-filled gauze, movable ligatures, etc. can cause this irritation during dressing change.
2. Hemorrhoid ligation thread falls off: starting 5-7 days after external peeling and internal ligation of mixed hemorrhoids, the hemorrhoid ligation thread begins to loosen and fall off. During this period, the anus falls strongly, which is the most common cause of anus fall. This situation continues until the hemorrhoid ligature is completely off. No special treatment is needed. The patient only needs to pay attention to rest, avoid squatting for a long time, keep the stool smooth, and ensure that the hemorrhoid ligation is completely necrotic and fall off naturally. Otherwise, it will easily fall off prematurely and cause hemorrhage. .
3. Stimulation of thread hanging: high perianal abscesses and high anal fistulas need to be treated with rubber bands for thread hanging. Before the rubber band falls off, the anus always drops, accompanied by falling pain. The fall of the tight line feels strong on the day, and then slowly reduce it until the rubber band falls off.
4. Edema irritation: Edema is prone to occur on the edge of the incision or the skin between the incision and the incision, which can cause anal drop due to stimulation. Therefore, after the operation, oral anti-swelling drugs should be taken and the defecation time should be controlled within five minutes to prevent skin edema. Once edema occurs, you can also take measures such as bathing with Chinese medicine and hot compress.
