Endoscopy procedures are performed for patients suffering from stomach or intestinal problems. During an endoscopy, a doctor inserts a lighted, flexible tube called an endoscope into a natural body opening. A camera in the endoscope allows the doctor to examine inside the patient's body without invasive surgery. Many people know about colonoscopy, an examination of the entire colon and gastroscopy, a visual examination of the stomach.

Endoscopy procedures are performed at the Procedure Center of South Sacremento. For any endoscopy procedures, patients need to be referred by their physician.


Barrx™ is a new treatment option for Barrett’s Esophagus, a condition that can often result from chronic heartburn or Gastroesophageal Reflux Disease, commonly referred to as GERD.

Dr. Imperato specializes in Barrx™ for Barrett's esophagus. It is performed in conjunction with an upper endoscopy and does not require any incisions or surgery. Barrx™ can minimize one’s risk of developing esophageal cancer if suffering from Barrett’s Esophagus as a result of GERD.


A colonoscopy is a procedure that allows the physician to look inside your large intestine, from the lowest part, the rectum, all the way up through the colon to the lower end of the small intestine.

For the procedure, you will lie on your left side on the examining table. You will probably be given pain medication and a mild sedative to keep you comfortable and to help you relax during the exam. The physician will insert a long, flexible, lighted tube into your rectum and slowly guide it into your colon. The scope transmits an image of the inside of the colon so the physician can carefully examine the lining of the colon. The scope bends so the physician can move it around the curves of your colon. You may be asked to change position occasionally to help the physician move the scope. The scope also blows air into your colon, which inflates the colon and helps the physician see better.

If anything abnormal is seen in your colon, like a polyp or inflamed tissue, the physician can remove all or part of it using tiny instruments passed through the scope. That tissue is then sent to a lab for testing.

A colonoscopy takes 30 to 60 minutes. The sedative and pain medicine should keep you from feeling much discomfort during the exam. You will need to remain at the colonoscopy facility until the sedative wears off, about one to two hours, before going home.


During balloon enteroscopy, a scope is inserted into the patient's mouth and fed through the stomach into the small bowel so that the doctor can get a first-hand look at any areas of concern. Alternately, the scope can be fed through the rectum to allow for study of the end of the small bowel. In both cases the patient is sedated. Because patients' judgment can be impaired after this procedure, they will not be released to public transportation, a taxicab driver, or even to walk home without another responsible adult to accompany them.

The risks associated with balloon enteroscopy are similar to those for colonoscopy and upper endoscopy (EGD) and include bleeding, perforation, and complications of sedation. There also is a less than one percent risk of bowel obstruction and/or inflammation of the pancreas with the balloon enteroscopy procedure.


A polypectomy is the surgical removal of a polyp, an abnormal growth of tissue on a mucous membrane. Surgeons may perform a polypectomy as part of an endoscopic procedure to remove polyps from many parts of the body, including the uterus, the cervix, and the small intestines.

However, polypectomy surgery is most often performed to remove polyps from the colon during a colonoscopy. Surgeons performing a colon polypectomy will remove polyps for further examination to determine if the polyps are cancerous or pre-cancerous.

Capsule Endoscopy

Capsule endoscopy is a way to record images of the digestive tract for use in medicine. The capsule is the size and shape of a pill and contains a tiny camera. After a patient swallows the capsule, it takes pictures of the inside of the gastrointestinal tract. The primary use of capsule endoscopy is to examine areas of the small intestine that cannot be seen by other types of endoscopy such as colonoscopy or esophagogastroduodenoscopy (EGD).

Hepatitis C Treatment

Recent advances in the number and types of medications available to treat Hepatitis C give us more options to consider when deciding on a treatment plan. For some people with a particular strain or genotype of HCV, these advances make the treatment regimen shorter in duration, less difficult to tolerate and more effective.


ERCP is short for: Endoscopic Retrograde Cholangiopancreatography, which is a procedure that looks at the bile ducts. It is done through an endoscope which is a thin, flexible tube with a tiny video camera and light on the end.

During an ERCP, the endoscope is inserted through your mouth, down through the esophagus and stomach, to the first part of the small intestines. In the small intestine, the endoscope is used to insert a small catheter into the bile and/or pancreatic duct. The endoscope is used by a highly trained subspecialist, the gastroenterologist, to diagnose and treat various problems of the bile ducts, pancreas, liver and gallbladder.
