Because the cyst can exist for a long time and remain unchanged for many years, it needs regular observation and no treatment. If the cyst grows up gradually, affects life, or is infected repeatedly, and often forms abscess, it is feasible to perform Papillostomy on the cyst. This method is simple, with little damage, and can still retain gland function. However, the stoma should be large enough. After the stoma, it is best to put a drainage strip and wash it with hydrogen peroxide or 2% iodophor once a day, * * * 3 ~ 4 times to prevent postoperative adhesion and closure, and form cysts again. Once the abscess is formed, it should be cut and drained. In recent years, CO _ 2 laser has been used for ostomy, which has the advantages of high treatment rate, no adverse reaction, simple operation, short treatment time and no need to suture the wound, and patients can be treated in outpatient department. Because of the high heat effect of laser, tissue cells can be coagulated and carbonized. Because of the affinity of laser to hemoglobin, it has good coagulation effect, less bleeding during and after operation, and can retain the normal function of glands, which has no influence on sexual life, no infection after operation and no need to use antibiotics. However, the application scope of this technology is still not wide, which needs further observation and research.
