Overview

I am an orthopaedic physician and work in adult reconstructive orthopaedics, predominantly with hip- and knee-replacement surgeries. I also help manage revision surgeries and take care of people with infections or fractures around their implants. I am interested in the whole continuum of care for arthritis and not just the surgical treatment of it. Even though I specialize in surgery, not everyone needs that treatment, and as an orthopaedic doctor, my role is to help direct the whole process. The care around revision surgeries at other centers is tertiary and many times not at the same place, but here at Duke we treat patients every step of the way at the same practice and have access to the latest treatments.

Dr. Jiranek is rated as an Experienced provider by MediFind in the treatment of Obesity. His top areas of expertise are Osteoarthritis, Infectious Arthritis, Septic Arthritis, Knee Replacement, and Hip Replacement.

His clinical research consists of co-authoring 143 peer reviewed articles and participating in 3 clinical trials. MediFind looks at clinical research from the past 15 years. In particular, he has co-authored 4 articles in the study of Obesity.

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. When I meet you in clinic, we will talk through all the treatments options for your condition so we make the best and safest decision for you and your family. My goal is to offer you the care that I would want for my family. Dr. Eckhouse is rated as a Distinguished provider by MediFind in the treatment of Obesity. Her top areas of expertise are Obesity, Obesity in Children, Hernia, Gastric Bypass, and Sleeve Gastrectomy.

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 the treatment of Obesity. His top areas of expertise are Obesity, Hernia, Short Bowel Syndrome, Gastric Bypass, and Sleeve Gastrectomy.
