Procedures Performed

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

Interventional Pain Management6
Epidural Steroid InjectionsSteroid medication is injected near irritated spinal nerve roots to calm inflammation causing sciatica or arm pain. Often used to make physical therapy tolerable rather than as a standalone cure. There are limits on how frequently they can be repeated.Nerve Block InjectionsAnesthetic, sometimes with steroid, is injected around a specific nerve to interrupt pain signals. Used both to treat pain and to identify its source, since relief from a precisely placed block points to the nerve responsible.Radiofrequency AblationHeat generated by radio waves disables the small nerves carrying pain signals from an arthritic spinal joint. Relief commonly lasts six months to two years. Because the nerves regenerate over time, the procedure can be repeated.Spinal Cord StimulationA device delivers mild electrical pulses to the spinal cord to interrupt chronic pain signals before they reach the brain. A temporary trial period is done first, so you can judge the benefit before committing to a permanent implant.Joint InjectionsSteroid or lubricating medication is injected directly into an arthritic or inflamed joint. Image guidance is often used to confirm placement. Relief typically lasts weeks to months and can make physical therapy more productive.Trigger Point InjectionsA local anesthetic is injected into a taut, tender knot of muscle to break the spasm-and-pain cycle. The appointment takes minutes and you can usually return to normal activity the same day.
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.

Lazy doctors who put off their job on Friday to get a long weekend. Actually it’s every day they leave before close so I guess they don’t want me to pay my bills.

Refusing all referrals if you don’t live in Moses Lake. Terrible service, rude receptionist who was startled by asking why that was the case.

I went with my significant other to an appointment with Dr. Orton and was disappointed at the "care" my significant other received. Once the doctor came in and introduced himself, he couldn't get out of the room fast enough. He left my significant other with more questions than answers, primarily because we were apparently disrupting his day. On our way out, Dr. Orton was stretched out at his desk doing nothing. Apparently, we were an inconvenience to his stretching session. We are going to ask to be transferred to another provider, one that doesn't act like doing his job is an inconvenience.

Waited over an hour to schedule an appointment that couldn’t be scheduled online. 25 min waiting just to be told I was connected to the wrong clinic. Transferred over to the correct one and waited another 45 min to get a rep. Always a wait in office too.

Nice clinic. Wait times are long but that is normal for any Hospital or Clinic. More so these days but it has always been a busy place. Going to a place like this expecting to be in then out is like asking a fig tree for an apple. It's clean and the staff is friendly. I keep getting sent here for random drug tests from my employer. Each time has been easy.
