title: [Operation technique determines frequency of recurrence of colorectal carcinoma].
abstract: BACKGROUND
  In order to investigate whether operative technique determines the 5-year recurrence and survival rates, we analysed the results obtained by two surgical departments using two different operative techniques. Department A: Removal of the tumour and a number of lymph nodes; department B: En-bloc resection in accordance with the requirements of standardised tumour surgery.
  
  
  METHODS
  The surgical results obtained with all patients with colorectal carcinoma operated on between 1984 and 1988 (department A: 152 colon and 53 rectal carcinomas; department B: 124 colon and 177 rectal carcinomas).
  
  
  RESULTS
  The local recurrence rate achieved by department A was significantly higher (colon carcinoma: department A 25 %; department B 10 %; rectal carcinoma: department A 54 %; department B 16 %). The 5-year survival rate for colon carcinoma was 65 % in department A, and 66 % in department B, the corresponding figures for rectal carcinoma being 49 % and 72 %, respectively.
  
  
  CONCLUSIONS
  The results indicate that carcinoma of the colorectum should be operated on only at an institution that complies with the standards required for surgery of colorectal carcinoma.
