Gina Adrales, M.D., M.P.H., joins the Johns Hopkins Department of Surgery as director of the Division of Minimally Invasive Surgery. Dr. Adrales is skilled in a variety of minimally invasive surgical techniques. Her areas of clinical expertise include gastroesophageal reflux disease (GERD), gallbladder disease, achalasia, splenectomy (spleen removal), bariatric surgery, and open and laparoscopic hernia repair (inguinal, ventral, incisional, umbilical, hiatal, paraesophageal).

Prior to joining Johns Hopkins, Dr. Adrales was Associate Professor of surgery at Dartmouth College Geisel School of Medicine in New Hampshire, where she directed the bariatric surgery program. She received her undergraduate degree from the College of William and Mary and earned her medical degree from the University of Virginia School of Medicine. She completed her residency at the Carolinas Medical Center and she performed a research and clinical fellowship in minimally invasive surgery at the University of Kentucky before her first faculty appointment at the Medical College of Georgia. While maintaining a busy clinical practice at Dartmouth, she earned her master’s degree in public health from The Dartmouth Institute for Health Policy and Clinical Practice.

A national leader in hernia surgery, Dr. Adrales serves on the Executive Council of the Americas Hernia Society and previously served on the Executive Council of the Americas Hernia Society Quality Collaborative to improve the safety and quality of hernia surgery. She is actively involved in a number of committees for the Society of American Gastrointestinal and Endoscopic Surgeons including various roles in surgical resident education, the development of the Fundamentals of Endoscopic Surgery and an innovative interactive hernia surgery education module. She is also a member of the American College of Surgeons, New England Surgical Society, Association for Surgical Education, and the Association of Women Surgeons.

Dr. Adrales’ research interests include clinical outcomes in minimally invasive surgery, bariatric and metabolic surgery, and hernia repair. She is interested in the geographic variation of bariatric surgery and the impact of physician availability, the application of minimally invasive surgical techniques in the older patient population, and the use of simulation in the training and assessment of surgeons in training. She has presented her work regionally, nationally, and internationally. more
