Rainer W.G. Gruessner (born 1957) is an American general surgeon and transplant surgeon of German descent, most noted as a surgical pioneer for his clinical and research innovations. Gruessner was the first transplant surgeon to perform all types of abdominal transplants (kidney, liver, pancreas and intestine) from living donors. He was also the first surgeon to describe a standardized technique for intestinal (bowel) transplantation from a living donor and then perform it successfully in 1997.〔(【引用サイトリンク】url=http://www.highbeam.com/doc/1G1-62632577.html )〕 He was the first surgeon to perform a combined laparoscopic removal of a portion of the pancreas and a kidney that were successfully transplanted simultaneously into a diabetic patient with end-stage renal disease. In 1998, Gruessner performed the first preemptive liver transplant from a living donor in an infant with oxalosis. In 2012, he and his team performed the first fully robotic removal of the pancreas and simultaneous islet transplant in a patient with chronic pancreatitis.〔(【引用サイトリンク】url=http://uanews.org/story/ua-surgeons-first-remove-whole-pancreas-combined-autoislet-transplant )〕 Gruessner was part of the teams that performed the world’s first split pancreas transplant and the world's first pancreas allotransplant after complete removal of a patient's native pancreas (both in 1988). He was involved in the development of transanal endoscopic microsurgery (TEM) techniques and conducted the first prospective study in 1989 that showed the superiority of ultrasound in comparison to peritoneal lavage in the diagnosis of blunt abdominal trauma. In the 1990s, he was the first to confirm in large clinical studies the efficacy of new immunosuppressive drugs after pancreas transplantation. Gruessner’s basic-science research has focused on different techniques of donor cell augmentation for tolerance induction after transplantation and on different rejection patterns in single versus combined transplants. In 2015, he and his team showed that 25 years of organ transplantation in the U.S. saved 2.2 million years of life in patients with end-stage organ failure. ==Biography and career== Gruessner was born in Mainz, Germany, where he also completed medical school at the Johannes Gutenberg Universitaet. In 1983, he was awarded “summa cum laude” for his doctoral thesis. After his residency, he completed a fellowship in transplantation immunology at the University of Minnesota. In 1991, he completed his professorial thesis (“Habilitation”, the German Ph.D. equivalent) at Philips Universitaet in Marburg, Germany. In 1991, Gruessner began his academic career in the U.S. as an Assistant Professor of Surgery at the University of Minnesota. Only five years later, he was promoted to full Professor with tenure. He went back to Europe for one year to assume the position of Chairman of the Department of General and Transplant Surgery at the University of Zuerich, Switzerland. In 1999, he returned to the U.S. to assume the roles of Vice Chair of the Department of Surgery and Vice Chief of the Division of Transplantation at the University of Minnesota. While in Minnesota, he and his team performed the state’s first living donor liver transplant, first living donor intestinal transplant, first combined living donor intestinal and liver transplant, and first multivisceral transplant.〔(【引用サイトリンク】title=Bowel transplant patients sent home; outlook good. )〕 His focus on living donor transplantation was boosted in 1996 when he received additional training in living donor transplantation at the University of Kyoto in Japan. In 2007, Gruessner was appointed Chairman of the Department of Surgery at the University of Arizona. He also served as the department’s Chief of Transplantation and Surgical Director of the Hepatopancreaticobiliary (HPB) Program at the University Medical Center. During his tenure, he transformed an ailing department into one with a national reputation specifically in transplantation and robotic as well as minimally invasive surgery through the recruitment of over 50 new faculty, the development of numerous new programs and divisions, and quadrupling of the department’s NIH support. In 2011, in his capacity as the department’s chairman, Gruessner oversaw the surgical management for the victims of the tragic Tucson shooting which included former US Congresswoman Gabrielle Giffords who suffered a critical gunshot wound to the head.〔 While in Arizona, Gruessner performed the state’s first living and deceased intestinal transplants, first multivisceral transplant, first pediatric living donor liver transplant and first autologous islet transplant.〔〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Rainer Gruessner」の詳細全文を読む スポンサード リンク
