This study aimed at evaluating the lymph node (LN) harvest after both open and laparoscopic colorectal cancer surgery.
In the period between 1996 and 2009, 404 patients with colorectal cancer underwent open resection, whereas 147 patients underwent laparoscopic surgery.
The overall number of harvested LNs was significantly higher in the laparoscopic group than in the open one (16.5 vs. 14.3, P<0.001). A higher number of LNs was found in moderately differentiated tumors of the laparoscopic group when compared with the open surgery group (16.7 vs. 14.2, P<0.01). The numbers of harvested LNs in the proximal tumors and in stage II and III tumors were higher in the laparoscopic group than in the open group (18.9 vs. 15.4, P<0.001; 17.9 vs. 14.2, P=0.002; 17.3 vs. 15.3, P=0.02, respectively).
Laparoscopic surgery for colorectal cancer can achieve LN retrieval similar to that achieved by the open approach.
