What is the cause of gas leakage after anal fistula surgery?

Leakage after anal fistula surgery may be related to incomplete healing of the surgical wound, impaired anal sphincter function, or postoperative infection. Treatment methods include enhanced postoperative care, drug therapy, and rehabilitation training.

1. The surgical wound has not healed completely

After anal fistula surgery, the wound needs a certain amount of time to heal. If the healing is not good, gas may leak from the wound. The wound should be kept clean and dry after surgery to avoid infection. Using potassium permanganate solution for a sitz bath twice a day for 15 minutes each time can help promote wound healing. Avoid sitting or standing for long periods of time to reduce anal pressure and promote wound recovery.

2. Impaired anal sphincter function

Surgery may cause some damage to the anal sphincter, resulting in a decrease in its ability to control gas discharge. Performing anal sphincter function training, such as levator ani exercises, 3 times a day, 15 minutes each time, can help strengthen the sphincter. Avoid eating foods that easily produce gas, such as beans, carbonated drinks, etc., to reduce intestinal gas production.

3. Postoperative infection

Postoperative infection may cause delayed wound healing or dysfunction, which may lead to air leakage. If you experience fever, local swelling, pain, and other symptoms, you should seek medical attention immediately. The doctor may prescribe antibiotics such as cephalosporins or penicillins to control the infection. At the same time, keep a light diet and avoid spicy and irritating foods to promote physical recovery.

Air leakage after anal fistula surgery requires targeted measures based on the specific cause. Postoperative care, drug treatment and rehabilitation training are key. If symptoms persist or worsen, seek medical attention in a timely manner to avoid delaying treatment. Through scientific care and reasonable treatment, most patients can restore normal function and improve their quality of life.
