Which of the following statements regarding open colon resection of a cancerous lesion is inaccurate?

The assertion that the resection of a cancerous colon lesion is always performed laparoscopically is inaccurate. While laparoscopic techniques have gained popularity in many surgical interventions, including colorectal cancer surgeries, they are not universally applicable or performed in all cases. Factors such as the size and location of the tumor, the patient's overall health, and potential complications can lead surgeons to opt for an open resection instead. Thus, stating that laparoscopic resection is the only method used does not account for the variability in clinical practice and the necessity for individualized surgical approaches based on the situation at hand.

In contrast, the other statements accurately reflect common practices in colon cancer surgery. Resection typically requires a sufficient distal margin to ensure clear margins, intraoperative anastomosis is frequently performed to restore intestinal continuity, and the resection of adjacent lymph nodes plays a crucial role in adequate staging and treatment of colon cancer.
