Dr. Sirinek has been a part of UTHSCSA for over 40 years. He received his medical degree from Marquette University School of Medicine. He then completed his General Surgery Residency at Ohio State University with Dr. Robert M. Zollinger. During this time, Dr. Sirinek was actively involved in basic and clinical GI physiology research and enrolled in graduate school, culminating in a doctoral degree in Physiology. He then served in the U.S. Army as a Major, MC, at the Burn Unit (Institute for Surgical Research) at Brooke Army Medical Center, San Antonio, TX, under Dr. Basil A. Pruitt.
Since being recruited by the first Chairman of Surgery, Dr. J. Bradley Aust, he has spent his entire academic and clinical career at UTHSCSA. He is presently Professor of Surgery, Vice Chairman for Academic Affairs and Professional Development and J.B. Aust, MD, PhD, Chair in Surgery. Dr. Sirinek served as Chief of the Division of General and Laparoendoscopic Surgery from 2001-2010. Prior to this, he also served as the General Surgery Residency Program Director for sixteen years.
His areas of expertise include complex procedures on the liver, biliary tract and pancreas, including the Whipple procedure. He has performed over 5000 cholecystectomies, primarily (99.5%) by the laparoscopic technique since 1991. In conjunction with plastic surgery and a wound care clinic, he has developed a large referral base for the treatment of patients with complicated abdominal wounds, incisional hernias, and enterocutaneous fistulas.
Dr. Sirinek has published over 200 book chapters, journal articles and abstracts. His areas of research have included: the role of gastrointestinal hormones in disease states including peptic ulcer, cirrhosis, and morbid obesity; the pharmacologic control and surgical management of portal hypertension; the physiological effects of laparoscopy; management of patients with complicated diverticulitis; the treatment of complicated biliary tract disease; and the use of both permanent and biologic mesh in the repair of complicated abdominal wall hernias. Honors awarded him include listings in Best Doctors in America, Who's Who, Texas Super Doctors, and Top Doctors in San Antonio. He recently completed six years of service on the American College of Surgeons Board of Governors and has been an examiner for the American Board of Surgery for 20 years.
