Procedures Performed

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

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.

Nicolle A. Farvour, MSN, NP at GI Associates is who I met with and she was wonderful! She listened, let me talk and tell her how I was feeling. She never interrupted me and was gracious with her time. She genuinely cared. When you don’t feel well, you want someone like Nicolle taking care of you.🩷

Nicolle NNP was awesome. It was obvious that she had reviewed my chart before we met, and she entered the room like a friend. She was very easy to talk to and was making sure she heard my concerns and questions. We came up with a plan together and I left the office with a clear care plan in my hand. Great service!

Edit: GI Associates reached out to see what they could do better. That means a lot in my book. They recognize the issues are are working to correct them. Moving this up to 4 stars. Origional review: This is a hard one. My doctor and his assistant are fabulous, seriously 11 out of 10. Scheduling, medical records, and their nursing line are nothing short of a disaster. GI Assoicates president Nalini M. Guda has to know how poor the support services are. Please do better.

Very helpful, friendly, and efficient! Anne, the person who helped me over the phone prepping was amazing! She was so friendly and answered all my questions. And when I met her the day of my procedure, she was even better in person. I've had a couple procedures there, and they really do a good job. Highly recommend them if your insurance allows it.

I would avoid this place like the plague! Totally painful experience just to get a preventative screening done because I was deathly afraid of the history of colon cancer in my family. They will do everything they can to be ambiguous at addressing your original concerns and reason for visit, not to mention how billing and insurance will be submitted. I was under the expectation that I was getting a baseline preventative screening done (I'm age 36 and I have had a close relative pass away from Colon Cancer at age 40). Should be a lot easier to have a simple preventative screening done to give you peace of mind. So stupid!! Sure enough, the week I got my procedure done I find out United HealthCare expands their Colon Screening benefits to cover the first one free of charge regardless of age. My luck. Now they will do noting to change my billing codes to match the ORIGINAL REASON that I came in and I am out thousands of dollars when my insurance would have likely covered it anyway as I would be high risk. They do not care to help you in any way to make your experience positive with billing or insurance. My carrier would probably understand this and cover me 100% anyway if they worked with me on this because I really did not have that much incentive to get it done when I could have just waited until Jan 1, 2026. But not I am responsible for a $2,700 bill. :-/ During my procedure, everything was clean as a whistle but for some reason they decided to take a biopsy for no reason which further complicated things for me down the road. I just feel like my discussions with the doctor and the office people were very confusing and I feel like I was mis-advised on what was going on throughout the entire process. Not a good feeling in the slightest. Throughout the whole process from my primary care to the specialist I was advised to get a preventative screening 5 years prior to the earliest family diagnosis for High-Risk, which likely would have been 100% covered if coded correctly. Do not go here it will cause you nothing but headaches! I'd rather get my procedure done abroad next time!! Sad this is how our healthcare system operates.
