Laparoscopic pelvic lymph node dissection in cadaver surgical training from the combined perspectives of urologists, gastroenterologists and gynecologists improves overall knowledge and technique: initial experience of multidisciplinary cadaver surgical training at a single institution in Japan.

Surgeons in Japan have recently become more familiar with cadaver surgical training (CST). Extended pelvic lymph node dissection (PLND) considering the vesicohypogastric fascia and ureterohypogastric nerve fascia is gradually being performed not only in urology, but also in gynecology and gastroenterology. We performed CST using a 76-year-old female cadaver who was fixed by the Thiel method, with the aim of confirming the differences in the extent of PLND performed by certified laparoscopic specialists in urology, gastroenterology and gynecology. Even in the common surgeries, there are still several areas where anatomical structures are poorly understood. In recent years, with the spread of robotic surgery, the techniques related to PLND in these three departments have gradually become similar. Through this CST program, we were able to understand the differences in procedures and the extent of PLND in these three departments. By continuing these CSTs, we hope that a standardized PLND procedure will be performed not only within the same department, but also between different departments, and that high-quality PLND will be safely performed.
