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.

Their billing is super questionable. This is one of those places where you end up getting multiple bills for a single service. They do not provide itemized statements even after request so it is not possible to verify that their charges are not duplicative with the hospital charges. If you find that kind of thing annoying, I think the Sutter center in Santa Rosa is a better option. Their billing was much clearer.

My wife stated that she got great service from all the medical professionals she dealt with. Unfortunately our dealings with one individual not involved in the medical process (front desk) tainted the review. This is a makeup review to account for that.

Very pleasant experience. Dr Hogan was so sweet and professional. My nurse was kind and personable. The anesthesiologist was friendly and funny. They had a lot of patients in at the same time but they buzzed in and out past each other very smoothly. My procedure started on time and went perfectly well.
