Core Tip
Core Tip: A retrospective analysis was conducted on 110 colon cancer patients who underwent total laparoscopic radical right hemicolectomy. This study compares the efficacy of improved π anastomosis and overlap anastomosis. No significant differences were observed between the two groups in terms of operative time, number of lymph nodes dissected, or postoperative hospital stay, however, the anastomosis time was significantly shorter in the improved π anastomosis group. The learning curve analysis shows that improved π anastomosis achieves proficiency earlier than overlap anastomosis.
