The Colon and Rectal Surgery Residency program at Penn State Milton S. Hershey Medical Center is a fully ACGME accredited program. There is one resident per year. The purpose of this residency program is to provide the Colon and Rectal resident with in depth comprehensive training in the surgical and medical management of the diseases of the colon, rectum, and anus. Clinical exposure to the full range of disease of the colon, rectum and anus is provided. The division has a strong interest in inflammatory bowel disease and is a regional referral center for patients with IBD, rectal cancer, and complex anorectal disease. The appointment is for one year clinical year. A second research year is available for those who are interested.

There are four General Surgery residents assigned to the service on a rotating basis: a chief resident, a second year resident, and two interns. In addition to the clinical staff, there is a full time basic science research staff consisting of one PhD, two postdocs, two residents, one clinical research fellow and three research technicians.
The Colon and Rectal Surgery service is divided into two teams (Blue and White). The Blue team consists of Dr. Koltun and Dr. Messaris, and the White team consists of Dr. McKenna, Dr. Messaris and Dr. Poritz.
The Colon and Rectal resident will rotate services every six weeks alternating with the Chief General Surgery resident, giving him/her six months on each service in total. While on each service the Colon and Rectal fellow will be responsible for the daily care of their assigned attendings inpatients, participate in clinic with the assigned attending and assist in the operating room. The Colorectal resident will spend a total of six months on each rotation. The time on each rotation will be broken up into six-week blocks to easily alternate with the Chief General Surgery resident so that there is no overlap. The General Surgery residents rotate on the Colon and Rectal Surgery service for three months at a time, and will spend six weeks on each rotation. At no time will both the Chief General Surgery resident and the Colon and Rectal resident be assigned to the same team. The junior residents on the service (R2 and interns) will work with both teams.
