Andreas M Kaiser, MD FACS FASCRS, a Professor of Clinical Surgery, has been on the faculty and in practice at USC since 2000. He graduated in 1988 from the University of Zurich in Switzerland. After an internship in Surgical Pathology, Dr. Kaiser trained in General Surgery at the University Hospital of Zurich (1990-1998), enhanced by a two-year research fellowship at Harvard Medical School/Beth Israel Hospital in Boston. He also completed a fellowship in Visceral Surgery at the University Hospital in Zurich, and in Colorectal Surgery at the Keck School of Medicine at USC. From 2008-2009, Dr. Kaiser served as the Interim Chairman of the Department of Colorectal Surgery at USC. He is board-certified by the Swiss Board of Surgery in General Surgery (1998) and Visceral Surgery (2006), and by the European Surgery Qualification Board in Coloproctology (2002). He is a Fellow of the American College of Surgeons (FACS) and the American Society of Colon and Rectal Surgeons (FASCRS), and a member of
several national and international professional associations and committees.
Dr. Kaiser has extensive experience in every aspect of even the most complex colorectal diseases. He serves as a referral center for challenging pathologies that may be beyond the scope of many other hospitals. Comprehensive and interdisciplinary treatment in the management of advanced colon cancer, rectal cancer, and anal cancer (primary, recurrent cancers, palliative setting) are as much routine as are inflammatory bowel disease (ulcerative colitis, Crohn’s disease), acute diverticulitis, functional disorders of the colon and rectum, and benign disorders of the anus. He has been instrumental and at the forefront in evaluating and adapting the newest technologies including robotic surgery, 3D-laparoscopic surgery, TEMS and advanced endoscopies, or sacral nerve stimulation and implants for fecal incontinence; he is one of few experts nationwide who understand and perform continent ileostomies, and he was instrumental in the development of the T-pouch. He is an expert for evaluation and treatment of fecal incontinence and not only offers sacral nerve stimulation but is also one of few surgeons who implanted the Artificial Bowel Sphincter or the magnetic ring (Fenix).
Dr. Kaiser's major areas of research interest include Colorectal Cancer, Inflammatory Bowel Disease, Diverticulitis, and Fecal Incontinence. Dr. Kaiser is not only committed to patient-care, but also to research and education.
He is Editor-in-Chief of "Clinical and Experimental Gastroenterology", and Associate Editor of Diseases of the Colon and Rectum", the official journal of the American Society of Colon and Rectal Surgeons; in addition, he serves among others on the editorial boards of “Surgical Endoscopy”, the "World Journal of Gastroenterology", and "World Journal of Gastrointestinal Pathophysiology". He serves/served as a member of several national committees of various societies (membership committee (chair), standards committee, program committee, CME committee, publications committee, guidelines committee). He served as Guest Editor on Hereditary Colorectal Cancer for "Seminars in Colon and Rectal Surgery", and was the lead author on a ASCRS Task Force for “New Technologies for Fecal Incontinence. He is a member of the NIH Advisory Board for the Pelvic Floor Dysfunction Network of the National Institutes of Health.
