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.
