Procedures Performed

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

Orthopaedic Surgery6
Knee ArthroscopyA camera and small instruments are inserted through incisions the size of a buttonhole to repair cartilage, trim a torn meniscus, or remove loose fragments. Because the joint is not opened fully, recovery is far faster than traditional open knee surgery.Shoulder ArthroscopyUses a small camera and instruments through tiny incisions to repair the shoulder joint — commonly for impingement, labral tears, or damaged cartilage. Most patients go home the same day and begin physical therapy within the first week.ACL ReconstructionRebuilds the torn anterior cruciate ligament using a graft, since a fully torn ACL does not heal on its own. The surgery itself is outpatient, but returning to cutting and pivoting sports typically takes nine to twelve months of structured rehabilitation.Rotator Cuff RepairReattaches torn tendons in the shoulder to the bone. Pain relief often comes well before strength does — a sling is typical for several weeks and full recovery commonly takes four to six months, with physical therapy doing much of the work.Carpal Tunnel ReleaseCuts the ligament pressing on the median nerve at the wrist to relieve numbness, tingling, and night pain in the hand. The procedure takes about 15 minutes under local anesthesia. Night symptoms often improve immediately; grip strength returns over several weeks.Joint ReplacementDamaged joint surfaces are replaced with implants, most commonly at the knee or hip. Once exclusively a hospital procedure, selected healthy patients now have this done at surgery centers and go home the same day with a structured recovery plan.
Otolaryngology (ENT Surgery)6
Tonsillectomy / AdenoidectomyThe tonsils and sometimes the adenoids are removed for repeated infections or sleep-disordered breathing. Recovery is notably harder for adults than children, with significant throat pain for a week or more and a real emphasis on staying hydrated.Ear Tube PlacementTiny tubes are placed through the eardrum to drain fluid and ventilate the middle ear, most often for children with recurrent ear infections. The procedure takes about 10 minutes and the tubes usually fall out on their own within a year.Sinus Surgery (FESS)A camera and instruments passed through the nostrils open blocked sinus drainage pathways, with no external incisions. Considered for chronic sinusitis that has not improved with medication. Congestion often worsens briefly before it improves.SeptoplastyThe wall of cartilage and bone between the nostrils is straightened to improve airflow through a blocked side. It addresses breathing rather than external appearance, though it is sometimes combined with cosmetic reshaping.Turbinate ReductionSwollen tissue inside the nose is shrunk to improve airflow, frequently at the same time as septoplasty. Often the difference between a nose that is structurally straight and one that actually feels open.LaryngoscopyA scope examines the voice box and vocal cords, used for persistent hoarseness, difficulty swallowing, or throat pain that has not resolved. Small lesions can sometimes be biopsied or removed during the same procedure.
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.
Podiatry (Foot & Ankle Surgery)6
Bunion Correction (Bunionectomy)The bony prominence at the base of the big toe is removed and the bone realigned, often with screws or plates. Recovery involves weeks in a protective shoe or boot, and swelling can persist for several months.Hammertoe CorrectionA toe permanently bent at the middle joint is straightened, sometimes with a temporary pin holding the correction. Considered when the toe rubs painfully in shoes or has developed calluses and sores.Plantar Fascia ReleaseThe tight band of tissue along the bottom of the foot is partially released to relieve stubborn heel pain. Reserved for cases that have not improved after months of stretching, orthotics, and other conservative treatment.Ankle ArthroscopyA small camera and instruments treat problems inside the ankle joint — impingement, loose fragments, or damaged cartilage — through incisions a few millimeters wide, avoiding a larger open exposure.Ingrown Toenail RemovalThe edge of a nail growing into the surrounding skin is removed under local anesthesia. When the problem keeps recurring, the nail-forming tissue at that edge is also treated so it does not grow back.Foot Fracture RepairBroken bones in the foot are realigned and stabilized with hardware so they heal in position. Because the foot bears your full weight with every step, alignment matters more here than the small bone size suggests.

I received a call tonight at 7:15pm just a 2 business days before I have surgery telling me that I need to pay a large copay before I have surgery. It would have been really helpful had I known this dinner to plan and prepare. I pay the copay to my surgeons office and didn’t realize I needed to pay for a facility fee! I have my FMLA approved and a driver and if I can’t make a payment plan I may have to reschedule this. I am at a loss of the inequality in this process. I have been going to providence for years and have had many surgeries and never have I had the process be like this especially for a large copay. It also says it’s an estimated fee amount!

Impeccably clean facility, super friendly pre-op and post op teams and head RN piped in Kendrick Lamar "They Not Like Us" before I drifted away. Suite 156 Ambulatory Surgery Center is a winner as they even sent me a Thank You card.

I want to talk about the wonderful doctors, the best in the world, the fantastic service that has been provided to me, Portland Providence Plaza, Ambulatory Surgery Center, LLC . Within a month, two operations were performed on different eyes.. . So it happened two years ago, my vision started to blur, then I stopped seeing in my eyes, I came to the Northwest Eye Health clinic in the spring of 2023, I was urgently provided with Daniel Holland !!! He looked at my eye and immediately prescribed me surgery , I waited 4 months.. . Coming to surgery at an eye clinic in the Clackamas area, the anesthesiologist found that my blood oxygen level had dropped to 83 and she did cancel my surgery . vision could disappear instantly and then reappear ... In 2025, as always in the spring, I again had a problem with my eyes, I again stopped seeing . This time, my eye clinic referred me to the Ambulatory Surgery Center, LLC, Portland Providence Plaza ! I came in for surgery this morning, I was greeted by a very affable Pre OP team Stephanie, RN !!! She took my blood pressure: it showed 166/84 ! I went with a great risk for surgery, for my health condition, on my hand I put a fob: Fall Risk .Then Michael, RN Golden, came up to me, very affable, who sympathized with my unfortunate experience .I am so grateful to the first anesthesiologist, Raghavan Rahul ... just the biggest of mine and a low bow to him, the entire team that participated in preparing me for surgery . Especially want to emphasize my attending physician, who did me surgery, who was not afraid of my health problems and risked to help me, this is Dr. Daniel Holland !!! He conducted such a unique and fantastic operation, he is so talented, intelligent, a highly professional specialist in his field !!! The operation was very successful, without any consequences, I was so pleased with the anesthesiologist Raghavan Rahul that I did not feel any pain, Michael Golden, and such an excellent, wonderful Stephanie !!! I am so glad that I was given the best service of my life..! The second surgery occurred a month later in the same composition, only the other was an anesthesiologist, Dr. Bolton! I’m grateful and very grateful to him, too ! That he supported me during the operation, held my hand, that most importantly, I did not feel pain, I saw how much Dr. Daniel Holland concentrated and sure . My lowest and most sincere bow to the best doctor in the world !!! Two operations were carried out without consequences, pain . I am so glad that my doctor gave me the opportunity to see the world in colors and the opportunity to see at all, Every minute I say to him and his team: “Thank you so much for the fantastic service ! I'm very proud of you. !!! Tatyana Bouwman

First of all I know there is only 21 reviews however I still can’t believe they are between 3-4. I spent a lot of time with my spouse in medical offices and I have to say 5 stars is not enough. Everyone I was in contact with A++++.
