One-stage suture of latent hair cyst and sinus tract resection

Primary suture cyst and sinus resection for suture surgery for the treatment of appendix cysts and sinuses. The appendix cyst is different in name and location. Such as posterior anal cyst, tail cyst, sacral cyst and latent hair cyst, etc., often due to secondary infection to form the corresponding sinus. There is no consensus on the etiology, but it is related to the congenital (exodermal sag) and acquired (the hair gradually enters the skin, becomes a short track, and gradually forms a sinus later). There are 3 types of pathology: 1 tail fossa: depression in the appendix joint, the humerus or the tip of the tailbone. On the median line, it is often single or multiple, and there are many sweat glands on the wall. Often asymptomatic, no clinical importance. 2 sinus sinus: the same position as the appendix sinus. When there is no complication in the sinus of the appendix, there is only 1 outer hole, and a small amount of secretion is discharged. Sometimes there is a bunch of hair in the hole. The sinus is often upward, and becomes shallow in the fascia of the humerus. Cyst. There are often acute and chronic infections in the sinus wall. 3 cyst: is the same lesion as the appendix sinus, the sac does not communicate with the outside world, if grown up, often caused by infection to form an abscess, rupture or incision to form a sinus. There are often hair and epithelial debris in the sinus. There is no need for treatment of the appendix fossa. If the appendix sinus and appendix cyst are infected, anti-infective treatment is needed. If an abscess is formed, it is necessary to open the drainage. If the above therapy fails, surgery is required. The operation should be based on the location, extent and degree of infection of the sinus. Treatment of diseases: fistula cyst Indication The first-stage suture of latent hair cyst and sinus resection is suitable for the appendix cyst and the small infection of the sinus in the midline. Contraindications Infected cysts and sinus should not be sutured in one stage. Preoperative preparation 1. Brush the skin 3d twice a day for 5 minutes. Shave the hair of the appendix before surgery. 2. Before operation, do iodine sinus angiography, positive and lateral slices to understand the relationship between sinus and the appendix. 3. Waist lumps and perianal shaving. 4. If necessary, warm saline enema. 5. Intestinal antibiotics were applied 1 day before surgery. Surgical procedure 1. First probe the direction, depth and extent of the sinus. Inject 2 ml from the sinus ostium with methylene blue. 2. According to the exploration, combined with the pigmentation range of the epidermis of the appendix, a fusiform incision was made with an electric knife. 3. Clamp the skin with tissue forceps, along with the bottom of the sinus, and make a large resection. Electrocautery stops bleeding. Excision of all cysts or sinus, but close to the cyst tissue to the patellofemoral fascia, all lesions were removed from the patellofemoral fascia, such as the patellofemoral fascia has been violated, but also need to be removed, sometimes need to remove the tailbone. 4. Cut the fascia above the gluteus maximus on both sides, and extend the incision to the outside 5~6cm, free the muscles and fascia on both sides, and suture it to the midline with a thick non-absorbent line or a 32-gauge alloy steel wire to avoid tension. 5. Trim the skin of the wound edge and suture the skin and the skin with no absorption line. complication 1. The diseased tissue should be cut, otherwise it is easy to relapse. 2. Stop bleeding carefully, otherwise it is easy to get infected.
