Electrical or Laser Coagulation or Infrared Photo Coagulation

These surgical techniques use special devices to burn hemorrhoidal tissue.

Endoanal or Endorectal Ultrasound

This diagnostic test uses sound waves emitted by a probe, or transducer, which is inserted into the rectum and bounces sound waves off tissues to produce an image on a screen.

Endoscopic Mucosal Resection (EMR)

a minimally invasive treatment for Barrett's esophagus, this procedure is used to remove a small cancer or localized area of high-grade dysplasia (abnormal cells). Using an endoscope, the abnormal areas are treated by injecting solution under the lining of the Barrett's area and applying suction to remove the abnormal tissue.

If EMR is used to treat an early-stage cancer, an endoscopic ultrasound will first be performed to make sure that the cancer involves only the very top layer of cells, and is an intramucosal cancer - one located on only the top mucous layer of esophageal cells.

EMR can provide a definitive proof of the tumor's depth. Healing usually takes about 4-8 weeks. Risks associated with this procedure include bleeding.

Endoscopic Retrograde Cholangiopancreatography (ERCP)

ERCP is a procedure that allows the physician to diagnose and treat problems in the liver, gallbladder, bile ducts, and pancreas. The procedure combines x-ray and the use of an endoscope - a long, flexible, lighted tube. The scope is guided through the patient's mouth and throat, then through the esophagus, stomach, and duodenum. The physician can examine the inside of these organs and detect any abnormalities. a tube is then passed through the scope, and a dye is injected which will allow the internal organs to appear on an x-ray.

If a duct is blocked, the physician can open it up by inserting a tiny stent (slender tube) into the duct through the endoscope, which can remain in place to keep the duct open. The physician may also take a small biopsy of tissue.

Patients fast for 12 hours, and are given a sedative and a local anesthetic, either in a spray or gargle, before undergoing an ERCP procedure. The procedure itself requires about an hour.


An endoscopy is an imaging technique that a gastroenterologist uses to see inside of the esophagus and stomach. It is a thin flexible tube with a light on the end, inserted through the mouth and down into the stomach. This procedure is done only when you are sedated.

Esophageal Manometry

This test helps determine the strength of the muscles in the esophagus. It is useful in evaluating gastroesophageal reflux and swallowing abnormalities. a small tube is guided into the nostril, then passed into the throat, and finally into the esophagus. The pressure the esophageal muscles produce at rest is then measured.


In this diagnosic test, a thin, lighted tube, or esophagoscope (an endoscope) is inserted through the mouth or nose into the throat and esophagus while the patient is given a local anesthetic. Small tissue biopsies can be taken through the scope, which pathologists analyze to determine the type and stage of cancer.

Esophagogastroduodenoscopy (EGD)

Also called an EGD or upper endoscopy, this procedure allows the physician to examine the inside of the esophagus, stomach, and duodenum using a thin, flexible, lighted tube, called an endoscope. The endoscope is guided into the mouth and throat, then into the esophagus, stomach, and duodenum. The endoscope also allows the physician to insert instruments through a scope for removal of a sample of tissue for biopsy, if necessary. Patients unable to tolerate an upper endoscopy may receive a capsule endoscopy, a non-invasive method that uses a small camera the size of a pill, which the patient swallows. The "camera pill" transmits photos to a recording device as it travels through the esophagus. The pill is later excreted.
