open incision submerged sinus tract resection

The incision open method is used for the surgical treatment of the appendix cyst and sinus. 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: anorectal abscess Indication Incision open method for latent sinus resection is applicable to: 1. Small and shallow sinus. 2. Multiple sinus ostiums with mild infections. Preoperative preparation 1. Preoperative sinus angiography, positive and lateral slices, to understand the relationship between sinus and the appendix. 2. Waist lumps and perianal shaving. 3. If necessary, warm saline enema. 4. 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. 4. According to the coloration of methylene blue, if there is no residual sinus, completely stop the bleeding, press the wound with iodoform gauze, and wrap it with Vaseline gauze dressing. complication 1. This method is simple and safe, but it takes a long time to heal. 2. The scar on the humerus sticks to the humerus. Because it is thin, it is often difficult to heal due to injury.
