title: Improved short-term outcomes of laparoscopic versus open resection for colon and rectal cancer in an area health service: a multicenter study.
abstract: BACKGROUND
  Evidence demonstrates short-term benefits of laparoscopic surgery for colon cancer. The situation for rectal cancer is less clear.
  
  
  OBJECTIVE
  This review assessed the use and short-term outcomes of elective open and laparoscopic colon and rectal cancer resections within an area health service.
  
  
  METHODS
  This was a multicenter, retrospective review of a prospective database.
  
  
  METHODS
  All elective colon and rectal cancer resections in the western zone of Sydney South West Area Health Service from 2001 until 2008 were included.
  
  
  METHODS
  Included were 1721 patients who underwent either a laparoscopic colon (n = 434) or rectal (n = 157) resection or an open colon (n = 742) or rectal (n = 388) resection.
  
  
  METHODS
  : Outcome measures included operating time, blood loss, adequacy of resection, conversion rate, intensive care unit admission, length of stay, and 26 acute postoperative complications.
  
  
  RESULTS
  Patients were matched for age, sex, ASA, BMI, and tumor stage. Laparoscopic surgery increased in frequency. Fewer patients experienced a complication in both the laparoscopic colon (28.8 vs 54.4%; p < 0.0001) and rectal (41.4 vs 60.3%; p < 0.0001) group irrespective of age. Laparoscopic operating time for colon and rectal cancer was 24.1 minutes (p < 0.0001) and 25.8 minutes (p < 0.0001) longer, with a low conversion-to-open rate (6.5% and 8.3%; p = 0.44). Laparoscopic surgery resulted in fewer transfusions (0.4 vs 0.7 units; p = 0.0028) and length of stay (7 vs 10 days; p = 0.0011) for colon cancers, and reduced intraoperative hemoglobin drop (20.5 vs 24.8; p = 0.029) and intensive care unit admissions (26.8 vs 36.3%; p = 0.032) for rectal cancers.
  
  
  CONCLUSIONS
  : This was a nonrandomized study with rectal cancers more often resected with the open technique (71.2 vs 28.8%; p < 0.001).
  
  
  CONCLUSIONS
  Within an area health service, elective laparoscopic resection for colon and rectal cancer had improved short-term outcomes in comparison with open surgery.
