"I see a broad range of problems related to the digestive system. Some of these are simple and straightforward, but others are very complex. Helping parents of these children to understand their child’s symptoms and working with them to treat the underlying condition is my main source of professional satisfaction." — Warren P. Bishop

Meet Warren P. Bishop, MD

Warren P. Bishop, MD, is director of the division of pediatric gastroenterology and medical director of the Pediatric Specialty Clinic at University of Iowa Stead Family Children’s Hospital. He received his training in Michigan and North Carolina and once worked at a military hospital in North Carolina. A native of Wisconsin, he joined UI Stead Family Children’s Hospital in 1989.

What factors sparked your interest in medicine?

I grew up in Milwaukee, and my uncle was a family practice doctor in Maquoketa, Iowa. He was always someone the family looked up to. To some degree, my mother fostered that interest [in medicine] in me. As long as I can remember, I wanted to be like my uncle. I was always interested in science, which helped. My identical twin brother became a doctor, too.

Why pediatrics, and especially pediatric gastroenterology?

When I was in my third year of medical school, I was exposed to all the different specialties. I enjoyed most of them. I actually did my pediatric rotation last. It was clear to me then that I would be a pediatrician. I liked the kids, and I liked the other pediatricians. I decided that was the path I was going to take.

Robert Kelch, MD, was my faculty mentor at the University of Michigan. He was an endocrinologist, and he pretty much had me convinced I should be an endocrinologist, too. But I had received an Air Force scholarship to medical school, and the Air Force said, ‘No, thank you.’ They wanted me to be a general pediatrician. I worked at an Air Force hospital in a small town in North Carolina where I encountered patients with various liver and GI [gastroenterological] issues. When I finished there, I went to the University of North Carolina to do a fellowship in pediatric gastroenterology.

What attracted you to the University of Iowa?

Coming to Iowa really felt like coming home. I had been to Iowa many times because my uncle lived in Maquoketa. My wife and I were happy to return to the Midwest. She is a professor, and she found a job here, too, which was part of it. Having gone to a small college in a small town [St. Olaf in Northfield, Minnesota] and a large university in a small city [University of Wisconsin-Madison], the idea of a university town—a place with liberal thought, safe streets, and cultural opportunities—appealed to me.

What would you like people to know about our children’s hospital?

There’s nothing like it in the state. The people here are sincere, caring, and hard-working. A big advantage for a child with complex illnesses is the depth of our faculty. I take care of a lot of kids with pretty significant illnesses that require an expert medical team. The people of Iowa need to be aware that they have a real gem of an institution here. In my gastroenterology division, we have doctors who have even more specialized expertise, such as in liver diseases, short bowel syndrome, feeding problems, and inflammatory bowel disease. I see children with a very broad range of conditions, from abdominal pain to liver transplant. One of our exciting new programs will be a multidisciplinary program for patients with chronic pain. It will open in the summer of 2017 when the first phase of renovations to the Pediatric Specialty Clinic is complete. I am working with rheumatology and neurology specialists on this so that we can provide service to children with many types of pain.

Where do you focus your research time?

Most of my recent publications have been in the area of constipation. I helped publish the first papers on using polyethylene glycol [brand name Miralax] to treat constipation in children. It had just come on the market for use in adults. We pioneered its use in children and showed the benefits of excellent efficacy and palatability [worked well and had an agreeable taste]. We published information on useful doses and safety. Now polyethylene glycol is used for children all around the world.

What are you looking forward to about our new children’s hospital?

First, it will provide a really wonderful environment for kids and families. It will offer all private rooms, nice scenery with its big windows, and it will certainly be quiet. Our division does somewhere close to 100 procedures a month, mostly endoscopies and placing feeding tubes. We will do those on Lower Level 2 of the new hospital.

With our new hospital, it will be obvious that this is a premier pediatric institution. It certainly will make it more attractive for new faculty to come to the University of Iowa.

What’s the best part of your job?

The children for sure. They are just fun—a breath of fresh air every day. I enjoy interacting with them. I see all ages, from babies to teenagers, with each age providing its particular rewards and challenges to the physician. I actually continue to follow many of my patients through their college years. Watching my patients grow is rewarding. I now have what I call “grandpatients;” I see the children of some of my former patients!
