Welcome to Colorectal Surgical Associates of Kansas City

Highly Specialized Diagnosis, Treatment, and Surgical Care of Conditions Related to the Colon and Rectum

Founded in 1991, we continue the 20-year tradition established by Drs. W. Edwin Conner and John W. Heryer as Kansas City’s leading colorectal specialists. We are proud to continue the legacy begun in 1979 by providing excellent colon and rectal care, in combination with the most advanced surgical techniques to treat patients suffering from diseases of the intestines, colon, rectum, and anus.

Our practice holds the Center of Excellence designation by Menorah Hospital for colon and colorectal surgery. We receive referrals from GI’s who entrust us with their patients throughout the Kansas City metro area and further. The physicians at Colorectal Surgical Associates are committed to treating patients as individuals, communicating their medical care in an understandable manner, and developing trusting doctor-patient relationships to foster the best possible treatment outcomes. Our surgeons are certified by the American Board of Colon and Rectal Surgery and the American Board of Surgery and have received extensive advanced training.

We provide the most up-to-date, advanced medical care and procedures regarding colon and rectal disorders. We make every attempt to provide non-surgical alternatives for pelvic floor dysfunctions, the most common of which is fecal incontinence. We use techniques such as behavior modification, pelvic muscle exercises, biofeedback, and functional electric stimulation (SNM therapy).

When colorectal surgery is necessary, we believe it should be precise, state-of-the-art, and minimally invasive to minimize patient discomfort and reduce healing time. That is why we are robotically trained and have received the Center of Excellence designation. The da Vinci Surgical System is designed to facilitate surgery using a minimally invasive approach. In fact, we are the robotic experts, training other surgeons on how to use this system. Other less invasive procedures offered include laparoscopic procedures and TEMs (Transanal Endoscopic Microsurgery).
