[The treatment of epithelial coccygeal cyst]

The dissection of coccygeal duct and closing the wound with a through perforated bathing drainage under modified epidural-sacral anaesthesia has been clinically approved. The operation was performed 3-4 days after two-step opening and cleaning of the abscess. The epithelial duct that doesn't have abscess symptoms should be dissected in one step operation. 68 patients underwent one-step surgery and in 125 cases two-step surgery has been done. The average time of staying in hospital was 15.3 days and 19.1 days, respectively. The double-step surgery of epithelial coccygeal duct decreases the level of postoperative septic complications and improves the functional and cosmetic results of the treatment.
