Preparing Japanese surgeons for potential mass casualty situations will require innovative and systematic programs.

INTRODUCTION: The ongoing state of global geo-political instability means that it is prudent to prepare civilian surgeons to manage major military-type trauma. Japan has enjoyed a prolonged period of peace and consequently it is unlikely that surgeons will have been exposed to a sufficient volume of cases. This study reviews the state of trauma training and preparedness in Japan and reviews the trauma workload of a major Japanese emergency medical center and compared with a major South African trauma center with the intention of quantifying and comparing the time needed to gain adequate exposure to major trauma at the two centers.

MATERIALS AND METHODS: The literature describing the surgical burden from a number of recent military missions was reviewed and the core surgical skills to manage military-type injuries were identified. We then went on to review all patients admitted to both Kurashiki Central Hospital (KCH) and Pietermaritzburg Metropolitan Trauma Service (PMTS) following trauma between the period September 2015 and August 2016. The burden of trauma at each center was quantified and the number of core surgical competencies or procedures performed at each center was then reviewed. These were then compared with the number of the core procedures which were performed on the reported military missions.

RESULTS: Three reports on military surgical missions were reviewed. These came from the Dutch, French and British military surgical services. The average number of each core procedures performed on each reported military surgery mission are tabulated in the text. The most common procedures were wound debridement and orthopedic fixation, followed by trauma laparotomy, neck exploration and thoracotomy. During the 12 month study period, 309 trauma patients were admitted to KCH. Of which 206 (67%) were male, and the mean age was 57 years. There were 10 penetrating injuries and 299 blunt injuries. Of the penetrating injuries there were no gunshot wounds. The mechanisms of injury for blunt trauma were as follows: Road traffic accidents (RTAs); 141 (47%), fall; 136 (46%) and other injuries; 22 (7%). In the same period, 2887 trauma patients were admitted by the PMTS. There were 1244 cases (43%) of penetrating trauma and 1644 cases (57%) of blunt trauma in PMTS. The mechanisms of injury for penetrating trauma were as follows: stab wounds (SWs); 955 (77%), gunshot wounds (GSWs); 252 (20%), and other injuries; 37 (3%) and for blunt trauma were as follows: assault; 739 (45%), RTAs; 669 (41%), fall; 166 (10%), and other injuries; 70 (4%). The exposure to all the key competencies required to manage trauma is overwhelmingly greater in South Africa than in Japan. The length of time needed to obtain an equivalent trauma exposure to that achieved in South Africa, working in Japan is prohibitively long.

CONCLUSION: Trauma training in Japan is hamstrung by a lack of clinical material as well as by systematic factors. Training a trauma surgeon is difficult. Developing a trauma system in the country may help address some of these deficits. South Africa in contrast has a huge burden of trauma and sufficient infrastructure to ensure that surgeons working there have adequate exposure to major trauma. Developing an academic exchange program between Japan and South Africa may allow for the transfer of trauma experience and skills between the two countries.
