Procedures Performed

Common outpatient procedures performed at this ambulatory surgery center, based on reported specialties.

Gastroenterology (GI Surgery)6
ColonoscopyA flexible camera examines the full length of the colon to screen for cancer and remove polyps before they become cancerous. Done under sedation, it typically takes 30 to 60 minutes. The bowel prep the day before is the part most patients find hardest.Upper Endoscopy (EGD)A thin camera passed through the mouth examines the esophagus, stomach, and the first part of the small intestine. Used to investigate persistent heartburn, difficulty swallowing, unexplained bleeding, or abdominal pain. Usually takes 15 to 30 minutes under sedation.Flexible SigmoidoscopyExamines the lower portion of the colon only, rather than its full length. Preparation is lighter than a full colonoscopy and sedation is sometimes unnecessary, but it cannot detect problems higher in the colon.Capsule EndoscopyYou swallow a vitamin-sized camera that photographs the small intestine as it passes through — a region that standard scopes cannot easily reach. There is no sedation and no recovery. The capsule passes naturally, and images are reviewed after the fact.ERCPCombines endoscopy and X-ray imaging to diagnose and treat blockages in the bile and pancreatic ducts, most often gallstones stuck in a duct. Unlike a routine endoscopy, it carries a meaningful risk of pancreatitis afterward, so it is used when treatment is likely rather than for screening alone.Hemorrhoid TreatmentShrinks or removes swollen veins in the rectum and anus using rubber band ligation, injection, or surgical removal depending on severity. Banding is quick and typically requires no anesthesia; surgical removal is more effective for advanced cases but recovery is noticeably more uncomfortable.

I had a GREAT experience at Maryland Center For Digestive Health (Dec. 2025) -- from the admitting secretary, to the nurses, to Dr. Raja Taunk -- all did a *great* job. I am so thankful for a smooth colonoscopy. And it's so great that you can use an Uber to get there and back. All were caring and attentive. Dr. Taunk was fantastic. I feel tremendous gratitude for all who served me there that day. Thanks so much! :)

Worst experience. They did not allow a support person when you’re waking up from anesthesia. The nurses were cold and rude. One asked me if I recalled what the doctor said to me upon waking and when I said no, she responded, well you were groggy and then walked away. Wth. I also ended up admitted to the hospital later that night. First time I’ve had any issues with my procedures. I’ll be going back to Anne Arundel Digestive Center. The staff is so wonderful there.

Had 2 prior colonoscopies here in the past and was impressed. Not this time. Front desk pleasant enough. After that was a total uncaring factory push through. Heard all of the nurses personal chatter waiting to be taken in. No eye contact from staff when explaining procedures-like robots. Worst anesthesiologist experience ever -rattled off some kind of explanation to me while being wheeled into procedure room-then woke up in the middle of procedure! Extremely painful! Scripted ending -“Enjoy your breakfast! “

I had a procesure here 2 months ago. Staff at front desk and check in were super nice. The nurses were very pleasant while I got prepped for procedure. My doctor, anesthesiologist, and nurse were very helpful and pleasant. I am happy with my procedure, but I was not happy with afterwards. No tea, ginger ale, orange juice, crackers, cookies..nothing offered to get you right after having not eaten for a full day and a half. I have had this procedure done 2 times in the past, and after waking from the procedure, I was greated with a good bedside manner, asked if I wanted liquids or some snacks. Very unprofessional in this regard.
