I felt a hard tube near my anus

The symptom of feeling a strip-like hard tube next to the anus is consistent with the characteristics of perianal abscess. Perianal abscess is mainly caused by bacterial infection and is a relatively common anorectal disease. Whether the strip-like hard tube felt near the anus is caused by perianal abscess cannot be determined by a single symptom, but we can first understand the disease of perianal abscess and make a comprehensive judgment based on our own situation, so that we can draw a conclusion.

Cause of this disease: This disease is a bacterial infection in the intestines. "Intestinal bacteria" is the source and the cause of the disease. The "anal sinus" is the entrance for infection and is also the internal opening for abscesses and fistulas. The "anal glands" are the route of infection, where infection occurs first and then spreads. The "perianal space" is the final site of disease. Intestinal bacteria enter the anal sinus and cause inflammation, blocking the anal gland opening, causing obstruction of anal gland fluid outflow and causing anal gland infection. The infection spreads to the perianal space through the muscle space and lymphatic vessels, and finally forms an anal canal and rectal abscess.

There are not many options for the treatment of this disease. The only cure is surgery, and the sooner the better. When there are no conditions or physical conditions that do not allow surgery, drug treatment can be chosen. 1. Drug treatment (1) Anti-inflammatory: For superficial abscesses, oral antibiotics can be used, generally broad-spectrum antibiotics. For relatively large abscesses, combined medication is required, such as metronidazole, ezetimibe sulfate, kanamycin, streptomycin, etc. (2) For external use, you can apply golden ointment, huoxue zhitong powder, sihuang ointment, yulu ointment, etc. (3) In the Ming Dynasty, Xue Yi’s “Essentials of Surgery” proposed the treatment concept of dispersing the disease at the beginning and expelling the poison during the pus formation stage. You can use Xianfang Huomingyin and Huanglian Jiedu Decoction with modifications. 2. Surgical treatment (1) Drainage of pus and decompression and local disinfection. Use a 20 ml syringe to pierce the abscess cavity from the weakest part of the abscess and draw out the pus, moving the needle up and down while drawing out the pus until there is no more pus to draw out. This method can temporarily reduce the tension of the abscess cavity and relieve pain. It is suitable for temporary emergency treatment, but it cannot replace surgery. If the disease progresses rapidly, such as necrotizing fasciitis, it should not be used to avoid delaying the disease. (2) Incision and drainage: Under local anesthesia, a small incision is made in the middle of the abscess cavity to drain the pus. After the operation, the abscess cavity is flushed with metronidazole and an oil gauze strip is placed for drainage. It is a temporary emergency treatment or the first surgery in a secondary surgical treatment. It can drain pus and quickly relieve symptoms, but it cannot replace radical surgery. It usually takes about 3 months for the fistula to form and the internal opening to be clear before radical surgery can be performed. (3) Radical surgery ① Low-position abscess - direct incision. ② Horse hoof abscess - incision and isolation. ③High-position abscess - hanging thread technique. ④High-position abscess - isobaric drainage. Because the cutting hanging wire still cuts off the straight anal ring, it is very painful and the wound is deep. In order to further reduce surgical trauma, bidirectional isobaric drainage surgery can be adopted. During the operation, a half-cutting hanging thread is used and a drainage tube is placed, so that the abscess cavity can heal without cutting the straight anal ring.
