Investigators have found that laparoscopic resections and open procedures yield a similar number of mesenteric lymph nodes[51,53]; however, the adequacy of distal resection margins for lower lying leftsided tumors has been questioned.[54] Additional concern has been raised by reports of early tumor recurrence at laparoscopic cannula sites.[55,-56] Currently, there are no data on long-term oncologic outcomes.
