Dr. Dua is a Clinical Assistant Professor of Surgery at Stanford. She received her undergraduate degree from the University of California, Los Angeles and her medical degree from Drexel University in Philadelphia. She completed her general surgery residency at Stanford University School of Medicine with a two year post-doctoral research fellowship in vascular biology. She then went on to do a one year fellowship in minimally invasive and robotic surgery at the Cleveland Clinic and a second two year fellowship in hepatobiliary and pancreatic surgery back at Stanford University prior to joining the division faculty. Her clinical focus is in gastrointestinal oncology with a focus on benign and malignant disease of the liver, pancreas, and bile duct. She also performs oncologic resections for tumors of the distal esophagus, stomach, and small intestine. Dr. Dua is the associate program director for the HPB fellowship, an active instructor in the Stanford University surgical clerkship curriculum for medical students, and also serves as the regional HPB Surgeon at the VA Palo Alto Health Care System. Dr. Dua participates in the Benign Pancreas Program at Stanford and her research includes both benign and malignant aspects of GI/HPB surgery with a focus on the management of severe pancreatitis as well as surgical strategies for the treatment of necrotizing pancreatitis. Other research interests include the application of minimally invasive approaches to the surgical management of HPB diseases including laparoscopic techniques in liver surgery and the use of laparoscopic and robotic platforms in pancreatic surgery. She currently has an ongoing clinical trial looking at the myoelectric activity of the stomach and intestine following pancreaticoduodenectomy as a function of predicting which patients are at higher risk of developing delayed gastric emptying or postoperative ileus. This study is being performed concurrently with the introduction of the division’s enhanced recovery after surgery perioperative care pathways to facilitate improved patient outcomes in those undergoing pancreatic resections.

I am a fellowship-trained minimally invasive and bariatric surgeon, who is involved in national surgical and specialty societies. My area of clinical and research interest is in outcomes of metabolic and bariatric surgery in special populations. As a surgeon at the Palo Alto Veterans Hospital, I am specifically interested in the outcomes of weight loss surgery in obese Veterans, who represent a population with a significant burden of co-morbidity, as well as challenging social, economic, and geographic circumstances. In addition, I am currently studying Veterans with spinal cord injury, with a goal to identify gaps in assessment and management of obesity in this special population.
