Dr. Dana D. Portenier

A significant portion of my practice involves advanced minimally invasive techniques in thoracic surgery to treat diseases such as lung or esophageal cancer. Another part of my clinical practice is spent taking care of patients with severe lung disease, especially those needing lung transplantation. Patients from all over the world come to Duke for lung transplantation. Research demonstrates that experience is very important in taking care of complex medical problems, both on the surgical side and on the medical side. We have one of the largest transplant centers in the world with excellent survival statistics, as well as the shortest wait list time. Instead of the national average which may be four to six months, our patients wait an average of about two weeks. One of the best aspects of being a patient or working at Duke is the people who work here. No matter how challenging the medical problems may be or what problems may arise, I know there’s a world’s expert a phone call away who can help intervene and I know that my patients will be cared for by committed Duke staff from across the hospital.

The majority of my practice focuses on abdominal wall surgery and the repair of ventral, incisional, and inguinal (groin) hernias. I chose to specialize in minimally invasive surgery because I saw the incredible benefits that these procedures provide for patients. By performing complex surgeries using either laparoscopic or robotic instruments, I am able to get patients back to their normal daily activities much faster and with significantly less pain. Whether I am repairing a hernia, performing surgery for weight loss, or helping to treat reflux, I will always try to offer a minimally invasive approach first and foremost. When I get the chance to meet you in the clinic we will discuss all of the possible treatment options for your condition and we will work as a team to pick which is the best choice for you. I feel incredibly fortunate to practice at Duke Health where we have incredible resources to take care of you no matter what problem you may have. I look forward to working with you and caring for you and your family. Dr. Greenberg is rated as a Distinguished provider by MediFind in the treatment of Esophagitis.
