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 ā€” 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.

My experience was top notch. The receptionist, nurses, anesthetist and Dr. Ramgopal were skilled, thorough, informative, patient and pleasant. I have been and have taken people to other facilities where you become a number on a screen. This facility and team provide a personal, welcoming experience.

Received a call the morning of my procedure and was asked to come in early due to cancellations. Working in the healthcare industry, I understand the need for utilization management and cleared out multiple work meetings in order to work with them. I checked in and sat in the overcrowded waiting room. My husband also took time off from work in order to accompany me, as is their requirement. 40 minutes later, there was no sign of an employed staff member, and the receptionist disappeared into the back as well. Finally I caught a nurse accompanying a patient out the door and asked her about my appointment. Sat for another 5 minutes, no sign of said nurse, and I walked out. Completely unacceptable. If they attempt to charge me for the procedure that did not happen, I will definitely be fighting the charges. Complete waste of time -- zero stars!!!

I had my endoscopy here and beginning with the information packet given ahead of time to the follow up phone call the day after, this is the BEST group of people. Dr. Matthews is so kind and he has surrounded himself with an amazing team that all made me feel so safe and taken care of. Iā€™m actually no longer nervous about colonoscopies or endoscopies!! Thank you ALL!

Dr. Williams is an excellent provider as is his team! Unfortunately he is now retired. Beware of hidden costs at this facility. Although I vetted my health insurance and the office vetted me and reviewed that actual costs related to a routine, over 60 years of age, colonoscopy, it was ascertained that my insurance covered this procedure. I was charged over 8000$ for a facility use fee!!! what is this.... 3 years later I am still on a payment plan. Needless to say I am not having a colonoscopy again, despite the health risk...

I had a colonoscopy and everyone was so nice and helpful. I was extremely nervous (my first time) Amy my nurse talked to me and calmed my nerves. The check in was quick and the wait was little to none! You can tell they care about their patients.
