Core Tip

Core Tip: The procedure for lateral lymph node dissection (LLND) is complicated, with a high incidence of complications. We developed a technique of laparoscopic LLND based on two fascial spaces to simplify the procedure. By cadaveric dissection, we found that urogenital fascia, vesicohypogastric fascia and parietal fascia lie side by side and formed two spaces (Latzko's pararectal space and paravesical space) which were the surgical area for LLND. 3D-Laparoscopic LLND in two fascial spaces was performed successfully in 20 patients with locally advanced low rectal cancer, and the results showed that it was a feasible, effective and safe procedure.
