title: ["Colon-/rectal carcinoma" prospective studies as comprehensive surgical quality assurance].
abstract: BACKGROUND
  Currently, only a small percentage of the diagnostic and therapeutic data on colonic carcinomas has been confirmed by data obtained in randomized controlled studies. For this reason, the results of prospective multicentre observational studies are extremely important.
  
  
  METHODS
  Within a multicentre observational study involving 75 surgical departments carried out between 01.01. and 31.12.1999, 3,756 patients with a colorectal carcinoma (2,293 carcinoma of the colon; 1,463 carcinomas or the rectum) were investigated prospectively using a standardised questionnaire.
  
  
  RESULTS
  The OP rate was 98.4%, the resection rate 92.5% (colon 94.1%, rectum 89.9%). The rate of rectal extirpations was relatively high at 30.3%. General postoperative morbidity was 27.4% (colon 27.0%, rectum 27.9%); the specific postoperative morbidity was 24.6% (colon 21.8%, rectum 29.1%). The anastomotic insufficiency rate was 5.2% (colon 3.7%, rectum 9.5%). The 30-day mortality rate was 4.7%, and the postoperative mortality rate 5.7%.
  
  
  CONCLUSIONS
  Surgical quality control in the form of prospective multicentre observational studies make possible the analysis of the therapeutic situation of a surgical disease under quality assurance aspects. At the same time, the comprehensive data material available will serve the specific planning of prospective randomized studies. With the aid of the present study, a basis for a thorough and complete evaluation of colorectal carcinoma has been created.
