Get to know Proctologist Dr. Johan Nordenstam, who serves patients in Chicago, Illinois.

Recognized as a highly trained proctologist, Dr. Nordenstam practices in the Division of Colon & Rectal Surgery at UI Health. He provides state-of-the-art care for patients with conditions of the colon, rectum, and anal canal. His interests include complex surgery for colorectal cancer and inflammatory bowel disease using minimally invasive methods — including trans-anal endoscopic microsurgery, robotic, and laparoscopic surgery — in addition to treatment options for hemorrhoids, fistula, and rectal prolapse.

The Division of Colon & Rectal Surgery at UI Health specializes in the evaluation, diagnosis, and surgical treatment of diseases of the colon, rectum, and anus. The team of surgeons work closely with other specialists to determine the best treatment plan for each individual patient, and they use the latest techniques in the evaluation and treatment of patients. At surgery, they focus on minimally invasive techniques for more successful procedures and faster recoveries.

Alongside his clinical role, Dr. Nordenstam serves as an Associate Professor of Surgery at University of Illinois at Chicago.

Educated in Sweden, he earned his medical degree from Karolinska Institute, after which he performed his residency at Danderyds Hospital. After moving to the United States, he completed fellowships in both colon & rectal surgery and minimally invasive colon & rectal surgery at the University of Minnesota – Twin Cities.

As a testament to his success, he is board-certified in colon & rectal surgery by the American Board of Colon and Rectal Surgery. It is a member of the American Board of Medical Specialties that issues certificates for practitioners of colorectal surgery.

Colorectal surgery is a field in medicine dealing with disorders of the rectum, anus, and colon. The field is also known as proctology, but this term is now used infrequently within medicine and is most often employed to identify practices relating to the anus and rectum in particular. A proctologist is a surgical specialist with a focus on diagnosing and treating disorders of the colon, rectum and anus. They often are seen for complex lower digestive tract issues or when surgery is needed to treat the patient.

Throughout his extensive career, Dr. Nordenstam has published his research in a number of scientific journals and has been a lecturer at national and international meetings.

On a more personal note, he speaks both English and Swedish.
