Gastrointestinal Procedures

Capsule Endoscopy

This is an exam of your digestive tract. It’s done with a tiny camera capsule you swallow. This exam is often used to see inside the small intestine, because that’s hard to reach with other types of scopes.

Colon Polypectomy

This procedure removes abnormal growths, called “polyps”, from the inner wall of your large intestine. The procedure usually lasts from 30 minutes to an hour.


This procedure is an examination of the large intestine. The physician will look for inflammation, ulcers, or abnormal growths called polyps. The physician uses a colonoscope. This is an instrument with a small camera attached to a soft, flexible tube. The procedure usually lasts from 30 minutes to an hour.

Percutaneous Endoscopic Gastrostomy (PEG) Tube Placement

During this procedure, a feeding tube is placed in your stomach. This tube will be used to give you food, liquids and medicines (if needed). A PEG tube is very helpful for patients who have trouble swallowing.

Endoscopic Retrograde Cholangiopancreatogram (ERCP)

This procedure is used to examine the duodenum, bile ducts, gallbladder and pancreatic duct. The physician uses a small camera, called an endoscope, which is guided down the throat. The procedure usually lasts from 30 minutes to an hour.

Upper Gastrointestinal Series (UGI)

This is an x-ray exam. It can help your doctor identify problems with your esophagus, stomach, and the first part of your small intestine. You may benefit from this exam if you have a problem such as heartburn, indigestion or unexplained pain in your chest or abdomen.

Liver Biopsy (Percautaneous)

During this outpatient procedure, one or more small samples of tissue are taken from the liver. These tissue samples will be studied under a microscope. A liver biopsy can help identify problems in the liver. If the patient has a liver disease, a biopsy can help doctors determine the type and severity.

Upper Endoscopy (EGD)

This procedure looks at the lining of your esophagus, stomach, and duodenum (that’s the first part of your small intestine). It’s done with an endoscope. That’s a special camera that looks like a flexible tube.


Monitored Anesthesia Care

Monitored anesthesia care is a type of anesthesia that makes the patient feel very relaxed. It reduces painful sensations and the awareness of pain. It is not intended to put the patient to sleep, and will wear off quickly after a procedure. Monitored anesthesia care is commonly used for simple procedures that can be completed quickly.

General Anesthesia

General anesthesia makes a person unconscious. People call this “put under” or “put to sleep.” But it isn’t the same as regular sleep. A person given general anesthesia cannot feel pain. And, the person won’t remember what happens during a medical procedure.

Anesthesia Overview

Anesthesia is the use of medications to block the pain of a medical procedure. The medications that block this pain are called anesthetics. Different forms of anesthesia are used to prepare patients for different types of procedures.

Regional Anesthesia

Regional anesthesia makes an area of the body numb to prevent the patient from feeling pain during or after a medical procedure. It can completely block sensation to a large area of the body. Regional anesthesia does not put a patient to sleep, but it is commonly used along with sedation. It may also be used with general anesthesia.

Local Anesthesia

Local anesthesia makes a part of the body numb to prevent a patient from feeling pain during a medical procedure. Local anesthesia is commonly used for many minor outpatient surgeries.
