ABSTRACT
Purpose@#Pelvic exenteration (PE) is a highly invasive procedure with high morbidity and mortality rates. Promising options to reduce this invasiveness have included laparoscopic and transperineal approaches. The aim of this study was to identify the safety of combined transabdominal and transperineal endoscopic PE for colorectal malignancies. @*Methods@#Fourteen patients who underwent combined transabdominal and transperineal PE (T group: 2-team approach, n = 7; O group: 1-team approach, n = 7) for colorectal malignancies between April 2016 and March 2020 in our institutions were included in this study. Clinicopathological features and perioperative outcomes were compared between groups. @*Results@#All patients successfully underwent R0 resection. Operation time tended to be shorter in the T group (463 minutes) than in the O group (636 minutes, P = 0.080). Time to specimen removal was significantly shorter (258 minutes vs. 423 minutes, P = 0.006), blood loss was lower (343 mL vs. 867 mL, P = 0.042), and volume of blood transfusion was less (0 mL vs. 560 mL, P = 0.063) in the T group, respectively. Postoperative complications were similar between groups. @*Conclusion@#Combined transabdominal and transperineal PE under a synchronous 2-team approach was feasible and safe, with the potential to reduce operation time, blood loss, and surgeon stress.

ABSTRACT
In accordance with the new model-core-curriculum for medical education, the current status of education about the science of radiation health was surveyed in all medical schools in Japan. Among the four learning points related to the “Biological effects of radiation and radiation hazards” , about half of the schools covered issues on “radiation and human body” and the “effect of medical radiation exposure” in one, or less than one, 60-minutes class, but did not touch on “radiation risk communication” and “radiological disaster medicine” . A significant deviation of human resources was also observed between schools. Learning tools such as presentation files and video content were preferred as education support materials. Therefore, development and distribution of the learning tools, especially in “radiation risk communication” and “radiological disaster medicine” , may be a first step to promoting high-quality education on the science of radiation health risk in each school’s curriculum.
