title: [Clinical value of laparoscopic surgery for colon cancer].
abstract: BACKGROUND
  Using data and analysis compiled in the nationwide German Colon/Rectal Cancer qualitative multicenter study, the aim of this study was to determine the value of laparoscopic surgery for colon cancer in clinical routine.
  
  
  METHODS
  From 1 January 2000 to 31 December 2003, patients with colon cancer resections were evaluated for short-term postoperative and long-term oncologic results associated with operative approach (laparoscopic vs conversion vs open).
  
  
  RESULTS
  Of 21,721 patients with colon cancer, 949 (4.4%) underwent laparoscopic resection. These patients were younger (P<0.001) with lower ASA risk factors (P<0.001) and earlier UICC tumor stages (P<0.001) than open resected patients. They also showed reduced overall morbidity (P<0.001), in-hospital mortality (P=0.001), and shorter hospital stays (P<0.001). The rates of intraoperative and specific complications remained unchanged. Nineteen percent of the patients had resections converted to open approaches. These had the highest overall morbidity and longest hospital stays. Their mortality was three times that of the group with complete laparoscopic resection.
  
  
  CONCLUSIONS
  The open approach remained the standard of surgical care in colon cancer for the study duration. Laparoscopic surgery was used in only a small number of patients. By virtue of preferential patient selection, better early postoperative and long-term results could be achieved for the laparoscopic group than with the open approach. Conversions were shown to be associated with inferior results at the high rate of 19%. To ensure optimal results, laparoscopic surgery for colon carcinoma should be conducted by an experienced surgeon in an appropriately selected patient pool.
