Services

At Advanced Endoscopy Centers, we focus on two core procedures: colonoscopy and upper endoscopy. These outpatient services are essential tools for both prevention and diagnosis in gastrointestinal health. Below, you’ll find clear information on each procedure, including what to expect and how to prepare.

Colonoscopy

A colonoscopy is a procedure used to examine the inner lining of the large intestine (colon and rectum). It is often recommended for:

What to Expect

You’ll receive detailed prep instructions before your procedure. Most patients are sedated, and the test typically takes about 15-20 minutes. During the exam, the physician uses a flexible tube with a camera to view the colon and may remove polyps or take tissue samples for further testing.

While the colonoscopy itself usually takes a relatively short time, the overall visit will take longer. Here’s why:

Before the procedure: You’ll check in, speak with the nurse and doctor.

During the procedure: The doctor uses a thin, flexible scope to examine the colon. If polyps or abnormal tissue are found, they may be removed or biopsied, which can extend the time slightly.

After the procedure: You’ll recover in a quiet area as the anesthesia wears off. Most people stay in recovery for 20–30 minutes before going home.

Plan to be at the center for at least 2 to 3 hours total. This allows time for every step to be done safely and thoroughly.

Upper Endoscopy (EGD)

An upper endoscopy, also called an EGD (esophagogastroduodenoscopy), allows your physician to examine the upper part of your digestive tract specifically the esophagus, stomach, and upper small intestine.

Common Reasons for an EGD:

What to Expect

You’ll receive clear preparation instructions in advance, including fasting for several hours before the procedure. Most patients are given light sedation to help them relax. During the EGD, the doctor gently guides a thin, flexible tube (endoscope) with a camera through your mouth and into your upper digestive tract.

The exam usually takes 5– 10 minutes.

If needed, the doctor may take biopsies (tissue samples) or treat minor findings during the same visit.

After the Procedure

You’ll rest in our recovery area while the sedation wears off. Expect to stay for about 20 to 30 minutes after the procedure is complete. Most patients resume normal activities the following day unless told otherwise.

Your doctor will go over any initial findings with you or schedule a follow-up if lab results (such as biopsies) are needed.
