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.

Starting at the front desk! The young lady was kind and helpful for what was to come after check in ! Thank you ! Next the nurse that came out to get me was very pleasant great chat as we went to the room ! Asked me questions about my medical history very easy to understand! Then she put the ivy needle in my right arm and didn't feel a thing !! It's hard to find a vain on me bet one push of the needle and she was done ! She took me to the next room to wait for the doctor he was recommended to me. He explained everything in more detail ! Next a nother young lady came and rolled me to the procedure room and she can drive a hospital bed with skills ! Two people were in the room waiting and explaining step by step what was going to happen before I took a nap lol ! I told them I have bad teeth and not one face changed ! He gave me the Anastasia and I said good night to them ! LOL !! When I woke up another lady asked if I waited water or juice I said yes please 🙏 I don't write much or type ! This place is amazing !!! Send my wife there and im confident she will be well taken care of !!! Thank you again all of you !!

The wait explains the service, if you want to go to a place you are just a number this is it. They are understaffed and busy I won’t come back.

I'm very happy with the care I receive from the staff and providers at this office. I would recommend them to anyone. Wait times are long, but that is the norm in WA. They have many locations and even offer telehealth.

Katie was wonderful! She's very knowledgeable and takes time to actually listen to you. This is the first time in almost a year that I've felt like someone is listening. She's wonderful!!
