What is a Direct Access Colonoscopy?

Patients at Kelsey-Seybold Clinic who have a primary care physician can now directly schedule appointments for a colonoscopy in the Ambulatory Surgery Center rather than being referred through a gastroenterologist prior to their procedure.

“The Direct Access Colonoscopy Program allows qualified Kelsey-Seybold patients to fast-track the colonoscopy procedure,” said John I. Hughes, M.D., F.A.C.P., F.A.C.G. with the Gastroenterology Department at Kelsey-Seybold Clinic. “This program provides a welcomed relief to a procedure that can often be thought of as inconvenient and worrisome for our patients.”

The Direct Access Colonoscopy Program at Kelsey-Seybold Clinic eliminates the need for healthy patients to meet with a Kelsey-Seybold gastroenterologist for a pre-consultation appointment.

To qualify, patients must have a Kelsey-Seybold primary care physician, be between the ages of 50-70 years, be in good health and have never had a colon screening in the past. These inclusions are assessed during a telephone interview with the patient and a nurse.

According to the American Cancer Society, colorectal cancer is the second leading cause of cancer-related death in the United States in men and women combined. Kelsey-Seybold gastroenterologists consider colonoscopy the preferred screening technique to help diagnose this disorder. A colonoscopy should be performed beginning at age 50, and every 10 years thereafter or as prescribed by the patient’s physician.

Any patient with outstanding or pending referrals to Cardiology or Pulmonary physicians, who requires supplemental oxygen therapy or who has been diagnosed with advanced renal disease, coronary artery disease, congestive heart failure, chronic obstructive pulmonary disorder or chronic lung disease needs to schedule a pre-consultation with a Kelsey-Seybold gastroenterologist. To schedule an appointment, contact your Kelsey-Seybold primary care physician or call 713-442-0000.
