title: Management of tailgut cysts in a tertiary referral centre: a 10-year experience.
abstract: OBJECTIVE
  Tailgut cysts are rare congenital lesions typically presenting as presacral masses. A variable clinical presentation often leads to misdiagnosis and unsuccessful operations.
  
  
  METHODS
  A retrospective analysis was performed of tailgut cysts presenting to one surgeon at St Mark's hospital between 2003 and 2013. The patient demographic data and clinicopathological and radiological features, together with perioperative details and recurrence, were reviewed.
  
  
  RESULTS
  A total of 17 patients (15 women) with a median age of 35 (21-64) years were included in the study. The mean duration of symptoms before referral was 40 months, with sepsis predominating in 12 cases. Fifteen of the patients had previously undergone surgery (mean 2.9 procedures). A posterior surgical approach was adopted in all patients with a coccygectomy performed in 13. A loop colostomy was formed in three patients. Two of them went on to have a secondary pull-through operation after an initial failed local repair of rectal injury. One case was reported to show malignant degeneration on histological examination. There was one recurrence during a median follow-up period of 13 (3-36) months.
  
  
  CONCLUSIONS
  Tailgut cysts are an uncommon yet important cause of chronic perianal sepsis. Suspicion should be raised in a patient, usually female, presenting with a history of unsuccessful procedures. Diagnosis can be made by clinical assessment and MRI. Complete excision usually resolves the problem.
