Role of laparoscopic surgery for treatment of early colorectal carcinoma

The first laparoscopic colorectal surgery was performed in 1991. Several reports have showed some advantages for the laparoscopic technique compared to open procedures, but the lack of well designed trials has produced doubts about the real advantage of laparoscopy for colorectal cancer. To date, retrospective and prospective evidence suggests that laparoscopy is as safe as conventional colorectal surgery. Two recent prospective, randomized trials have showed that the short-term outcome is not compromised after laparoscopy for colorectal cancer. Furthermore, less pain, faster recovery of respiratory parameters, and better preservation of cell-mediated immune function have been associated with the laparoscopic technique. Laparoscopic surgery for early colorectal cancer may have a role in a well selected group of patients.
