The impact I have on my patients is what I enjoy most about being a weight loss surgeon. It is amazing that we can do an operation that not only helps a patient lose weight, but also fixes their diabetes, high blood pressure, and cholesterol, along with giving them a better quality of life. There are a lot of options these days for people who are considering weight loss surgery. It’s important for patients to take into account each institution and what resources they have available. Duke is fully equipped to take care of complex cases in a safe manner. We have a multi-institutional team that’s been around the Triangle the longest and has the most experience. Almost every patient comes back after surgery and we see some of their previous medical conditions go away. That’s a good definition of success. Dr. Portenier is rated as a Distinguished provider by MediFind in Gastric Bypass. His top areas of expertise are Obesity, Hernia, Short Bowel Syndrome, Gastric Bypass, and Sleeve Gastrectomy.

The majority of my practice is focused on treating patients with the disease obesity. I am a general surgeon who completed a fellowship in advanced minimally invasive and bariatric surgery, so that I can offer obesity care using advanced endoscopic, laparoscopic, and robotic approaches. I am also board certified in obesity medicine and my hope is to approach patients comprehensively. Obesity is a chronic disease that needs lifelong follow up. This approach takes a team and here at Duke Health, we have a fantastic team. A true multidisciplinary approach helps us meet all the needs of our patients. With my training, I also treat gallbladder disease, stomach diseases, acid reflux, and hernias. With my laparoscopic and robotic training, I can offer the safest and best approaches for your general surgery needs.

I came to Duke from Nebraska, where I was a medical director for two weight loss surgery programs. I decided to become a weight loss surgeon because it gives me the chance to establish a long-term relationship with my patients. For many patients, weight loss surgery often feels like a fresh start, since they are able to get rid of some of the health problems they may have acquired due to their weight and do certain activities they couldn’t do before. I get a thrill out of being able help patients start this “new life.” My approach to care involves listening to what the patient wants out of the surgery, educating them about various treatment options and performing a full evaluation. Then, I work with the patient to come up with a treatment plan that meets their physical and mental health needs. Dr. Sudan is rated as a Distinguished provider by MediFind in Gastric Bypass.

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 see patients who have heart disease, and I work to prevent them from having any bad consequences of that disease. I also see patients who are having symptoms and do diagnostic work to see what cardiovascular condition they may have to explain their symptoms. I also take care of patients who either have known or suspected genetic cardiovascular disorders. Our genetics clinic is one of the only adult cardiovascular clinics in the Southeast. We take care of patients who have a variety of cardiovascular genetic disorders or who have strong family histories of heart disease and want to come in for testing. Duke has a strong collaborative approach to patient care.

Interventional radiology allows me to perform minimally invasive procedures to treat a wide array of problems. Through tiny incisions on the skin that most frequently don’t require stitches, I insert a catheter, direct it to the problem area using imaging guidance (x-rays and/or ultrasound), and treat the problem. My areas of clinical focus include women (fibroids, adenomyosis, post-partum hemorrhage, placenta increta or percreta, occluded Fallopian tubes, chronic pelvic pain from pelvic congestion), children (venous malformations, arteriovenous malformations, combined malformations, difficult venous access), and lymphatics (lymphatic malformations, lymphoceles, chylothorax, chylous ascites, plastic bronchitis, protein losing enteropathy).
