Veterans Affairs General Surgery

About Us

The Palo Alto Veterans Health Care System is a Dean’s affiliated hospital of Stanford University and serves the veteran population in VISN 21 (Hawaii, Northern California, and Nevada) as well as taking complex surgical care cases as referrals from VAs around the nation. Our immediate catchment area extends from Yosemite, the central valley, east bay, peninsula, south bay, and south coast past Salinas. We are the designated complex care facility for referrals from VISN 21. We are proud to serve our veteran patients and fulfill the promise made by President Lincoln in his second inaugural address “To care for him who shall have borne the battle and for his widow, and his orphan.” VA care has been shown to be a leader in US medicine in outcomes, minimization of racial disparities in care, and complex care of the veteran patients who often have other comorbities compared to the general population.

Program Priorities

Our service provides state of the art open, laparoscopic, and robotic treatment of typical surgical conditions such as hernia, soft tissue masses, endocrine, gallbladder, colon and rectal surgery. We have two recognized areas of special emphasis-complex gastrointestinal cancer care including stomach, liver, pancreas, intestine, sarcoma, melanoma, and colorectal tumors. The VA has been an ACS Commission of Cancer Certified Caner program for more than 20 years. In addition, we are a national referral center for bariatric surgery which features a recognized multidisciplinary approach to the complex patient with morbid obesity.


Our faculty are all board-certified Stanford faculty members with additional training in liver/pancreas/gallbaldder, minimally invasive surgery, bariatrics, robotics, endocrine, hernia, sarcoma, and colorectal surgery. We are a training site of the Stanford medical school and Department of Surgery. Patients are focused to a surgical specialist who is an expert in their specific disease area.

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.
