Laparoscopy: Colon CancerLaparoscopy: Colon CancerConclusionConclusion

Laparoscopy for colon cancer has shown to be potentially Laparoscopy for colon cancer has shown to be potentially superior to laparotomy in regard to short-term benefits superior to laparotomy in regard to short-term benefits and equivalent with regard to long term benefitsand equivalent with regard to long term benefits

Available data appear to support that laparoscopic Available data appear to support that laparoscopic colectomy and conventional open colectomy have either colectomy and conventional open colectomy have either similar or superior long-term outcomes (Level 1 similar or superior long-term outcomes (Level 1 evidence)evidence)
