About Pokala Ravi Kiran, MD:
Dr. Ravi P. Kiran is the co-director of the Global Center for Integrated Colorectal Surgery and IBD Interventional Endoscopy at NewYork-Presbyerian/Columbia University Irving Medical Center. Prior to that, he served as chief and program director of the Division of Colorectal Surgery at NewYork-Presbyterian/Columbia University Irving Medical Center for over a decade. He is also the Director of the Center for Innovation and Outcomes Research in the Department of Surgery. Dr. Kiran, a renowned surgeon-scientist with expertise in inflammatory bowel disease, colorectal cancer, and other complicated colorectal conditions, joined NewYork-Presbyterian/Columbia from the Cleveland Clinic, where he was staff surgeon and head of the research section in the Department of Colorectal Surgery and director of its Rupert B. Turnbull Jr. School of Enterostomal Therapy.
Dr. Kiran brings a wealth of experience in laparoscopic and open colorectal surgery, anorectal procedures and reoperative abdominal and pelvic surgery. With expertise in inflammatory bowel disease (IBD) like complex Crohn’s disease and ulcerative colitis, he specializes in bowel conservation as well as avoiding an ostomy (external bag) for these conditions when others may be unable. Having trained with Dr Victor Fazio at the Cleveland Clinic, he is an expert at pouch procedures. In addition to J and S pouch creation, he has experience in the repair, revision and redo of these pouches when pouch failure occurs. In addition to IBD, he is also expert in the surgical management of primary and recurrent colon and rectal cancer, diverticulitis, enterocutaneous fistula, functional bowel problems including constipation, incontinence and pelvic floor disorders. He is one of only a few highly skilled surgeons world-wide to perform continent ileostomy reservoir procedures and other complex operations to avoid a permanent ostomy after rectal or colon resection. As a researcher, Dr. Kiran has specific interests in surgical outcomes and quality and in evidence-based strategies for inflammatory bowel disease and other conditions. With a joint appointment at Columbia University Vagelos College of Physicians and Surgeons and at Columbia’s Mailman School of Public Health, Dr. Kiran facilitates research collaborations in epidemiology between the Department of Surgery and the Mailman School.
Dr. Kiran received his medical degree from and completed surgical training at Osmania Medical College in Hyderabad, India, and received advanced training in colorectal surgery in the United Kingdom. He completed his general surgery residency at Yale-Saint Mary’s Hospital and Bronx-Lebanon Hospital Center and fellowship training in colorectal surgery at the Cleveland Clinic. He is board certified in surgery and in colon and rectal surgery from the American College of Surgeons (FACS) and the American Society of Colon and Rectal Surgeons (FASCRS) and is a fellow of the Royal Colleges of Surgeons of England and Glasgow.
The author of more than 200 peer-reviewed publications, Dr. Kiran is also an editor and reviewer for numerous prominent journals and textbooks. As a student and physician, he has earned several distinctions, including the National Merit Scholarship and Gold Medals during his medical education and surgical training in India, Resident Researcher of the Year during surgical residency, Teacher of the Year in Colorectal Surgery at Cleveland Clinic in 2011, and the ASCRS Travelling Fellow Award in 2012. He has been voted to the list of Best Doctors in New York many times.
Dr Kiran has a patient-centered approach to care and is available to see patients at the Main Campus, Midtown and New Jersey colorectal surgery office locations.
