With a faculty of 22 colon and rectal surgeons, a broad exposure to the full breadth of colon and rectal surgery is provided.

Each candidate must have completed a minimum of five (5) years training in an ACGME approved general surgical training program.

Clinical Rotations

The residents rotate between different clinical sites/rotations twice over the course of the academic year. Each rotation is structured to provide endoscopy, operative and private office/outpatient clinical experience. In addition, some rotations have special emphasis on preoperative/postoperative care, pelvic floor evaluation, endorectal ultrasound, TEM, and robotic surgery. The residents work under the supervision of teaching faculty. At the University of Minnesota Medical Center and Veterans Administration sites, they collaborate with more junior residents and medical students in the teaching pyramid. In the private practice rotations, they work one-on-one with the faculty.

Clinical Research

There is ongoing clinical and basic science research at the University of Minnesota. Each resident is assigned a research topic and expected to prepare an abstract for submission to the American Society of Colon and Rectal Surgeons. These topics are typically retrospective studies of a particular condition. There are many other opportunities to co-author chapters or participate in other research projects.
