title: [Case-control studies of two kinds of method for the treatment of lumbar tuberculosis with psoas abscess].
abstract: OBJECTIVE
  To compare two kinds of method for treating lumbar tuberculosis with psoas abscess, to provide reference for clinical reasonable select of therapy treatment.
  
  
  METHODS
  From January 2010 to January 2013,42 patients with lumbar tuberculosis combined with psoas abscess with obvious surgical indications were enrolled, including 24 males and 18 females with an average age of (38.5 ± 10.2) years old ranging from 21 to 63 years old. All patients were followed up for 18 to 24 months with an average of 20.9 months. Twenty-two patients underwent posterior vertebral body lesions cleared, bone graft fusion and internal fixation and percutaneous puncture catheter drainage for treatment of psoas major abscess as group A, and twenty patients underwent one-stage extraperitoneal approach to remove abscess, posterior vertebral body lesions cleared, bone graft fusion and internal fixation as group B. The operative time, loss of blood, length of hospital stay, clinical cure rate and other clinical results for the two groups were analyzed and compared.
  
  
  RESULTS
  The loss of blood was (452.3 ± 137.6) ml in group A and (603.5 ± 99.6) ml in group B, there was significant statistical difference (P < 0.05). The time of operation was (193.6 ± 91.2) min in group A and (230.5 ± 56.6) min in group B, there was significant statistical difference (P < 0.05). The time of operation and the loss of blood in group A were obviously less than which in group B. In group A 20 cases were cured and 2 cases relapsed, 19 cases were cured and 1 case relapsed in group B, there was no significant statistical differences between two groups regarding cure rate with chi-square test (χ² = 0.000, P = 1.000). All patients in two groups obtained good clinical curative effect. There were no significant statistical difference between two groups regarding for length of hospital stay with t-test (P > 0.05).
  
  
  CONCLUSIONS
  Lumbar spinal tuberculosis with psoas abscess is not absolute indications for anterior open operation. Compared with the combined anterior and posterior surgical procedure, the percutaneous puncture catheter drainage combined with posterior debridement, interbody fusion and internal fixation can achieve the same clinical effect but less trauma for the patients.
