Sydney vascular surgeon Dr John Swinnen OAM has risked his life treating hundreds of gunshot wounds, bomb blast injuries and performed countless operations not often seen in developed countries like ours. Dr Swinnen's voluntary work with Médecins Sans Frontières (MSF) has taken him to the world's most dangerous regions, including Eastern Congo, the Afghanistan-Pakistan border, Yemen and Gaza. He discusses the kinds of operations he performs in these combat zones, and why he's continued to volunteer his time for one or two months every year for the last decade.
