Additional Surgical and Treatment Options

Appendectomy

If you’re suffering from appendicitis, you need quick treatment. Appendicitis causes severe pain and requires emergency surgery to remove the infected appendix. At AnMed, our skilled surgeons perform the appendectomy through small incisions, reducing your recovery time and getting you back to your normal life as soon as possible.

Barrett's Esophagus Treatment

Left untreated, GERD can lead to Barrett’s esophagus, a condition where the lining of the esophagus is replaced by cells similar to those in the small intestine. This increases the risk of esophageal cancer.

To prevent cancer, radiofrequency ablation (RFA) may be recommended. This outpatient procedure uses heat to destroy precancerous cells, allowing healthy tissue to grow in their place. RFA is a minimally invasive treatment that helps reduce cancer risk and supports long-term digestive health.

Colon and Rectal Surgery

When you need specialized colorectal care, Dr. Brian Sadowski, Anderson’s only colorectal surgeon, offers the expertise you need close to home. He treats conditions like ulcerative colitis, rectal prolapse, and fecal incontinence using the latest minimally invasive techniques. These procedures often involve smaller incisions, allowing for a faster recovery and less time in the hospital.

Dr. Sadowski also performs surgeries that remove the colon while preserving bowel function—without the need for a permanent ostomy. His goal is to help you maintain your quality of life while providing the best possible surgical outcomes.

Fistula, Fissure & Hemorrhoid Treatment

Conditions affecting the anus and lower rectum can be uncomfortable, but our specialists can provide effective treatments to help relieve pain and improve your quality of life. These conditions include:

  • Anal fistula: Small holes that develop after an abscess
  • Anal fissure: Painful tears in the skin around the anus caused by hard stools
  • Hemorrhoids: Swollen, painful veins in the rectum that cause itching and discomfort

GERD Surgery

If you suffer from acid reflux or heartburn, or gastroesophageal reflux disease (GERD), you know how uncomfortable and disruptive the symptoms can be. GERD happens when stomach acids flow back into the esophagus due to a faulty valve, and over time, it can cause more serious issues like Barrett's esophagus, which increases the risk of cancer.

At AnMed, we offer Transoral Incisionless Fundoplication (TIF) to repair the faulty valve without the need for incisions. This approach reduces recovery time and the risk of complications compared to traditional surgery, helping you get back to your routine faster.

Gallbladder Removal

If you need gallbladder removal due to gallstones or pain, da Vinci® Surgical System allows your surgeon to perform the procedure through a single small incision. This technique leads to less scarring, a quicker recovery, and minimal pain. Dr. Paul Frassinelli, who has been performing robotic gallbladder removals longer than any other surgeon in South Carolina, uses this advanced approach to help you feel better faster with a less invasive procedure.

Hernia Repair

A hernia occurs when an organ, such as the intestine, pushes through a weak spot in the abdominal wall, causing pain, swelling and a visible bulge. Hernias don’t go away on their own and surgery is usually necessary to correct the condition. At AnMed, our surgeons use advanced techniques to repair the hernia with minimal incisions, helping you recover faster and get back to your life sooner.
