Core tip: Several randomized controlled trials have reported the short-term advantages of laparoscopic resection compared to open resection for both colon and rectal cancer. In addition, there is evidence showing the non-inferiority of the laparoscopic approach in colon and rectal cancer surgery in long-term survival. Conversion to open surgery has been reported in up to 30% of laparoscopic colorectal cancer resections. However, both short and long-term outcomes in these patients are unclear. Therefore, we discuss the currently available evidence of the impact of conversion of laparoscopic resection for colon and rectal cancer on both short-term outcomes and long-term survival.
