Three\u2010dimensional images were constructed at a workstation and showed branches of the iliac artery and vein, ureter, urinary bladder, and enlarged lymph nodes. All members of the surgical team participated in preoperative simulation using the 3\u2010D images.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 10 patients with advanced lower rectal cancer and enlarged lateral pelvic lymph nodes underwent laparoscopic unilateral LPLD after total mesorectal excision, tumor\u2010specific mesorectal excision, or total proctocolectomy. Four of the 10 patients (40%) had variations in pelvic vascular anatomy. The median operative time for unilateral LPLD was 91\u2009min (range, 66\u2013142\u2009min) and gradually declined, suggesting a good learning curve. The median number of lateral pelvic lymph nodes harvested was nine (range, 3\u201316). The median estimated blood loss was 13\u2009mL (range, 10\u2013160\u2009mL). No conversion to open surgery or intraoperative complications occurred.
