Answer

In adults, benefits of minimally invasive surgery include decreased length of stay, smaller incisions, less narcotic use, less blood loss and lower transfusion rates, and improved pulmonary function after surgery. No long-term differences have been demonstrated regarding oncologic outcomes. [42]  

Surgical colon cancer guidelines widely cite consensus for a goal of at least 12 lymph nodes for an adequate staging. There is a positive correlation between the number of lymph nodes examined and survival for patients with stage II and III CRC. No difference has been shown between open and laparoscopic approaches regarding the number of lymph nodes examined, as well as local or distant recurrence rates. [42]

Early reports of a high rate (21%) of port site recurrence raised concerns about minimally invasive surgery. However, larger multicenter, randomized, controlled trials have not shown any significant increase in wound site recurrence. Both laparoscopic and open CRC resections have wound recurrence rates of less than 1%. [42]
