The Division of GI Oncology uses advanced, minimally invasive techniques to treat a range of colorectal disorders, benign and malignant, including prolapse and hemorrhoids, diverticulitis and colorectal cancer. Physicians evaluate, diagnose and treat fecal incontinence using pre-operative testing, endoscopy, manometry, electromyography and nerve studies. Physicians may recommend surgical repair or biofeedback. They also treat rectal cancer, inflammatory bowel disease, restorative proctocolectomy and treatment of renal bleeding and discomfort after radiation.
