title: [Multivariate analysis of pharyngo cutaneou fistulas after larynx cancer and lower pharynx cancer surgery].
abstract: OBJECTIVE
  To investigate the relative factors of pharyngo cutaneou fistulas after larynx cancer and lower pharynx cancer surgery.
  
  
  METHODS
  The clinical datas of 87 larynx cancer patients and lower pharynx cancer patients admitted were retrospectively analyzed. According to the type of postoperative complications all cases could be divided into pharyngo cutaneou fistulas group and no pharyngo cutaneou fistulas group. Thirty-eight kinds of factors,including age, clinical stage, plasma electrolytes level and type of procedure are in the multivariate analysis, and the variability indicators are in binary-regression analysis.
  
  
  RESULTS
  Eleven patients had pharyngo cutaneou fistulas (12.64%). Univariate analysis indicated that BMI, pre-operative serum potassium, operation time, cervical lymph dissection, post-operative prealbumin, post-operative hemoglobin, infection and delayed union of incision were the risk factors of pharyngo cutaneou fistulas (P < 0.05). Logistic stepwise regression analysis indicated that post-operative prealbumin and operation time were the independent risk factors.
  
  
  CONCLUSIONS
  To avoid pharyngo cutaneou fistulam, it is very necessary to correct electrolyte disorder and negative nitrogen balance. To shorten the operation time, to avoid incision infection and delayed union were helpfulness, too.
