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.

It was great to see how the staff works so well together. They were consistent in their rhythm and flow. Almost like they could sense each others moves. I felt very comfortable and welcome. All my questions were answered, they were professional and very kind. My wait was very short. I trust my Dr. and his surgical team completely. I give them 5 stars.

Obviously everyone knows what they are doing! Very streamlined and professional. From the moment I walked through the door I felt cared for and respected . The anesthesia doc is a mainstay there. Can’t imagine trusting anyone else with my care. He is personality plus and very present with you . Dr. Guo, so sad he is retiring , well deserved . If all docs could be as warm and reassuring as he is.
