Procedures Performed

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

Ophthalmology (Eye Surgery)6
Cataract SurgeryThe clouded natural lens of the eye is removed and replaced with a clear artificial one. It is one of the most common outpatient procedures performed in the country, usually takes under 30 minutes per eye, and is done under light sedation with numbing drops rather than general anesthesia.LASIK / Refractive SurgeryA laser reshapes the cornea to correct nearsightedness, farsightedness, or astigmatism, reducing dependence on glasses or contacts. The procedure itself takes minutes per eye. Vision is often noticeably better within a day, though it can take several weeks to fully stabilize.Glaucoma SurgeryCreates a new drainage path for fluid inside the eye to lower internal pressure. Glaucoma damages the optic nerve silently, so the goal is preventing further vision loss rather than restoring vision already lost. Several minimally invasive options are now performed in outpatient settings.Retinal SurgeryRepairs the light-sensitive tissue at the back of the eye, most often for a detached or torn retina, or for bleeding related to diabetes. Timing matters — a detaching retina is treated urgently because delay increases the risk of permanent vision loss.Eyelid Surgery (Blepharoplasty)Removes excess skin and fat from the upper or lower eyelids. When drooping upper lids block part of the visual field, the procedure is functional rather than cosmetic and is often covered by insurance if visual field testing documents the obstruction.Corneal TransplantReplaces damaged or clouded corneal tissue with donor tissue. Modern techniques often replace only the affected layer rather than the full thickness, which shortens recovery. Vision improves gradually over months, and stitches may stay in place for a year or longer.
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.
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.

I arrived early for my appointment in November, checked in, and was seated. Everyone who arrived after me was called back to registration and went back for their procedure while I waited 50 minutes for registration and to be called for my procedure. I was asked to pay deductible/facility charge of $797 before receiving procedure. I paid the fee and was to be refunded after insurance paid fee. My insurance paid the fee in January. Here it is end of March and I am still waiting for refund from Wesmark Ambulatory Surgery. I am very disappointed with their registration and insurance policies. Also, please be careful to treat everyone fairly regardless of race, ethnicity and nationality. The procedure went very well, and I had a very caring nurse. Thank you! Sumter Gastroenterology for a procedure well done!

Candie sutton made sure that I had top quality service. I went in for a retainer after having my braces removed this week. She made sure that my retainer fit comfortably. She is very passionate and I was very pleased after my appointment.

I recently had a colonoscopy here with Dr Angus and his team. I was very nervous about the procedure but I have to say the staff was very calm and friendly and efficient. Everyone treated me well and the parts of the experience that I remember were very pleasant. The worst part was the colon prep but unfortunately that comes with the territory so to speak and the staff here couldn't help that. 🤣
