General Surgery

We perform many surgeries with minimally invasive procedures. This type of surgery is performed with much smaller incisions than we use for traditional surgery and results in less pain and scarring and faster recovery times. When you come in for your appointment, your doctor will explain your options and whether this is the most appropriate surgical approach for you.

Our general surgery services include (but aren’t limited to) a wide range of procedures:

(Procedures shown in bold indicate those areas where we offer specialized diagnostic programs.)

  • Appendectomy
  • Breast surgery
  • Colon and rectal surgery
  • Endoscopy and colonoscopy
  • Esophagus surgery
  • Gallbladder surgery
  • Hemorrhoid surgery
  • Hernia surgery
  • Intestinal surgery
  • Lung surgery
  • Preventive health screenings
  • Reflux surgery

Breast Surgery

You may have detected a small lump in your breast that wasn’t there last month. Or your doctor may be concerned about a suspicious spot on your mammogram. Or you may have been told you need breast surgery for breast cancer and are looking for the right surgeon.

At Grants Pass Surgical Associates, your well-being is our first priority. We help you cope with the stress and fear you are feeling with accurate diagnosis and supportive care.

Breast Surgery

Comprehensive breast evaluation

First, we want you to know that being sent to a surgeon does not mean you have cancer. Non-cancerous breast conditions are very common and don’t require treatment. Once we have done a thorough exam, we will provide you with our diagnosis and all the information you need to understand it.

Expert cancer treatment

Should we detect cancer, we will work with you and your other doctors to determine the best treatment options for you. Surgery is the most common first step in treatment and our surgeons are highly trained in both surgical oncology (cancer-related surgery) and breast reconstruction.

Breast procedures we perform routinely:

  • Surgical biopsy: A biopsy is the only way to know for sure if you have breast cancer. It involves removing and examining part or all of a suspicious cyst or tumor in the breast tissue. A tissue sample can be suctioned out through a needle (which may be done without anesthesia) or surgically removed through a small incision. Some women decide to start with a surgical biopsy and, if cancer is detected, have it removed at the same time.
  • Lumpectomy: In this procedure, only the breast tumor and a small amount of surrounding tissue is removed, conserving as much of the breast as possible.
  • Mastectomy: This surgery involves the removal of all breast tissue, which we can do, in most cases, without removing the muscles under the breast.
  • Axillary lymph node dissection: Removing affected lymph nodes may be necessary if cancer has spread outside the milk ducts of the breast. Lymph nodes may be removed at the same time as a lumpectomy or mastectomy.
  • Sentinal lymph node dissection: In some cases, a less invasive procedure can be used to remove the lymph node closest to the area of breast that contains the cancer. This node is considered the first to filter fluid away from the affected area. If this node is clean, it’s likely other lymph nodes will not be cancerous. This is a procedure that should only be done by a surgeon with significant experience performing this technique. Our surgeons are well-trained in this area and will offer the treatment, when appropriate.
  • Breast reconstruction surgery: When you’ve had a full or partial mastectomy, you will have the choice of having your breast reconstructed to look like your natural breast. We perform breast reconstruction using an artificial implant, tissue from another part of your body or a combination of both.

Endoscopy & Colonoscopy

You don’t have to live with undiagnosed digestive pain, heartburn, weight loss, vomiting or difficulty swallowing. Grants Pass Surgical Associates can provide answers quickly and comfortably using a non-surgical procedure called endoscopy. We also perform routine colonoscopies to screen for colorectal cancer.

The doctors at Grants Pass Surgical Associates are specialists at detecting all gastrointestinal conditions with the latest tools and techniques. We take special care to make your endoscopy experience painless and stress-free.

Endoscopy & Colonoscopy

Get answers and solutions for gastrointestinal pain. When your pain or discomfort is in your esophagus (the tube that connects your throat to your stomach), stomach or upper part of the small intestine, we perform an upper endoscopy to detect problems your primary care doctor may have missed. During this diagnostic procedure we insert a thin, flexible tube with a light and camera at its tip—called an endoscope—through the mouth and throat.

The endoscope sends images of your digestive tract to a monitor for evaluation of a range of conditions that include:

  • GERD (gastroesophageal reflux)
  • Esophageal cancer
  • Ulcers
  • Inflammation
  • Precancerous growths (polyps)
  • Bowel obstruction
  • Hiatis hernias

Schedule your colonoscopy to prevent colorectal cancer. Colorectal cancer is the most avoidable and treatable form of cancer when detected early. The best way to screen for it is with a colonoscopy. A colonoscopy involves placing an endoscope through the rectum and into the large intestine (colon) to search for precancerous or cancerous growths.

If we find any growths we can remove them during the colonoscopy and test them for cancer. Removing precancerous growths prevents them from becoming cancerous. Colon cancer is slow growing, so even if a growth is cancerous, detecting it early makes the cancer easier to treat.

When to have a colonoscopy

  • You are 50 years old and over and have been told by your doctor to get screened.
  • You have a family history of colorectal cancer. (Have your first screening 10 years before the age your first-degree relative was diagnosed.)
  • You have already been diagnosed with polyps or early stage colorectal cancer.
  • You have a family history of inherited breast, uterine or ovarian cancer.

Varicose Vein Treatment

We can provide minimally invasive treatment for varicose veins. These bulging, rope-like veins could mean that tiny valves in the veins in your legs have stopped working properly to keep blood flowing in the right direction.

Varicose Vein Treatment

Proper diagnosis of varicose veins is critical to successful treatment. If you suspect you have varicose veins, you’re not alone. Over half the population over 50 suffer from some form of them. Many younger people do too. Varicose veins can ache and cause feelings of fatigue or cramping. You may also have skin conditions like a rash, redness or sores on your legs. Standing or sitting for too long can make these symptoms worse.

Accurate diagnosis is done using duplex ultrasound. Your surgeon will first conduct a physical exam and ask you questions about your general health, medical history, and symptoms. He or she will also examine the texture and color of any prominent veins. Depending on findings, we may recommend a duplex ultrasound test that uses sound waves to measure the speed of blood flow and examine the structure of your veins. This should take about 20 minutes per leg and gives us the information we need to make the most accurate diagnosis possible.

When the veins in your legs are healthy, blood circulates smoothly from your feet to your heart. But sometimes the blood in your leg veins can pool and increase the pressure in your veins. This often happens when you don’t get proper exercise or sit or stand too long. Eventually the walls of those veins weaken. Pooling blood can also damage the one-way flaps, called valves, that keep your blood flowing in the right direction. The result can be varicose veins.

While varicose veins are not life threatening, a severe case can slightly increase your chance of developing a deep vein thrombosis (DVT). DVT can cause sudden, severe leg swelling and always requires immediate medical attention. With proper diagnosis, we can make sure this never happens to you.

Advanced, safe treatments have you back on your feet quickly. Thanks to advances in medicine, we can offer a variety of treatments for both varicose veins and spider veins (dilated blood vessels that appear on the legs, hands, chest and face). Most procedures can be done without any sedation so you can go right back to your normal activities.

Our vein treatments include:

  • Compression therapy: Compression stockings are the most conservative approach to treating problem veins in your legs. These prescription stockings put pressure on your veins to stop excess blood from flowing backward and pooling. They also help heal skin sores and prevent them from returning.
  • Sclerotherapy: During this simple treatment your physician injects a chemical into spider or small varicose veins through a tiny needle. The affected vein then shrinks and is absorbed into the body. Healthier veins take over the job of moving blood to your heart. You may experience tenderness at the injection site for up to two weeks.
  • Radiofrequency ablation (RF): This is a minimally invasive treatment that uses radiofrequency energy to heat and seal spider veins or small varicose veins shut. Using ultrasound for guidance, we deliver heat through a tiny catheter directly into the problem vein. At Grants Pass Surgical Associates, we use the latest technology, called the VNUS ClosureFAST, which shortens the procedure time while providing optimal results. You can generally walk immediately after the procedure but should rest for the first few days to avoid bruising and swelling. You may experience soreness for a week or more.
  • Ambulatory phlebectomy: For larger varicose veins, we may recommend a minimally invasive outpatient procedure called ambulatory phlebectomy. After applying local anesthesia, your doctor will make several tiny incisions to remove the veins at the leg’s surface. No stitches are required and you should be able to walk out of the office. You may need to wear compression stockings for several weeks to minimize bruising and aid healing. You can generally expect great long-term results from this treatment.
  • Vein stripping: In more severe cases of varicose veins and other chronic vein diseases, we may recommend a surgical procedure called vein stripping. This outpatient procedure is performed with general or local anesthesia. Your surgeon will make a small incision in the groin area and usually another incision in your calf below the knee. After tying off (ligating) the affected superficial saphenous vein in your leg, we remove (strip) it through these incisions. Blood then circulates through nearby veins with healthy valves. The incisions are closed with stitches. Vein stripping usually takes 60 to 90 minutes. You will need to wear bandages to control the bleeding and swelling for 3 to 5 days and wear compression stockings for several weeks. You should be able to return to work within a few days of the procedure.
