Looking inside the body with an endoscope (a long, thin, flexible fiber-optic tube attached to a tiny high-definition video camera) allows gastroenterologists to examine your digestive tract for ulcers, polyps, malignancies and other abnormal tissue. We can also remove suspicious polyps or growths, stop bleeding with cauterization and place a stent to open an obstruction and restore the flow of bile.
Our specialized endoscopy procedures include:
- Endoscopic retrograde cholangiopancreatography (ERCP): During this procedure, which incorporates detailed X-rays during a visual inspection of the bile duct, pancreatic duct and gallbladder, your colon doctor may simultaneously remove gallstones from the bile duct and place stents.
- Endoscopic ultrasound (EUS): A GI doctor examines deeper layers of the esophagus, stomach, small intestine, bile duct, pancreas and gallbladder and performs nonsurgical biopsies for hard-to-reach lesions.
- Upper endoscopy, also known as esophagogastroduodenoscopy (EGD): This procedure explores the esophagus and stomach. Doctors also use an upper endoscopy to remove growths, perform biopsies, dilate the esophagus and treat bleeding.
A colon cancer screening, also known as a colonoscopy, is the single most effective early detection system to prevent colon cancer. The second leading cause of cancer death in the U.S., colon cancer generally has no symptoms in the early stages. If detected early, colon cancer is 90-95 percent curable.
During a colonoscopy, a doctor uses a lighted, flexible scope with a tiny camera inside to view the entire length of the colon and see any signs of trouble that may be developing. If polyps are discovered, they can be removed immediately with another tiny instrument inside the scope.
Advanced technology available at Parkland Medical Center and from our partners at Salem Radiology allows us to perform some colon screening procedures as virtual colonoscopies using computed tomography.
Scheduling a colonoscopy
Current guidelines suggest starting your colon cancer screenings at age 50 years old, so talk to your doctor about when and how often you need a colonoscopy. Medicare and most insurance plans cover colon cancer screenings for people 50 years old and older.
Preparing for your colonoscopy
The day before your colonoscopy, you’ll need to clean out your colon completely. Digestive health specialists use several different types of preparation for cleansing the colon, and your colonoscopy doctor can help you decide which is best for you. We suggest that you eat light, easily digestible foods for several days before your colonoscopy.
After your colonoscopy
As soon as the sedation wears off, your physician will discuss your results with you. If any polyps were removed, they will be sent to the lab for a biopsy and evaluation. Results will be available in a few days.
Our GI doctors will sometimes perform surgery to manage chronic conditions and to avoid a colostomy. If you need GI surgery, rest assured that you'll receive comprehensive care in our full-service hospital. We have all the amenities necessary to make your procedure and stay as comfortable as possible.
