Gallstones / Gallbladder Disease

Your gallbladder is a pear-shaped organ under your liver. It stores bile, a fluid made by your liver to digest fat. As your stomach and intestines digest food, your gallbladder releases bile through a tube called the common bile duct. The duct connects your gallbladder and liver to your small intestine.

Your gallbladder is most likely to give you trouble if something blocks the flow of bile through the bile ducts. That is usually a gallstone. Gallstones form when substances in bile harden. Rarely, you can also get cancer in your gallbladder.

Many gallbladder problems get better with removal of the gallbladder. Fortunately, you can live without a gallbladder. Bile has other ways of reaching your small intestine.

Hernia Repair

 Hernia is a condition when there is a weakness or tear in the abdominal wall. The risk of hernias if untreated is gangrene of the intestines.  The most common location is the groin. However, hernias may occur through previous incisions and at the diaphragm, the muscle which separates the chest cavity from the abdominal cavity. For groin hernias, repairs can be done in several different ways.  The two main categories of repairs are the open technique and the laparoscopic technique. Hernia repair is generally a very safe procedure that causes a minimum of complications.

Mesh in Hernia Repair (Also called a "patch," or "screen," mesh) has been used for about 25 years, and represents a leap forward in the art of hernia repair. Repairs utilizing mesh patches may also be called a "Lichtenstein Repair," because it was a surgeon named Irving Lichtenstein, MD, who popularized tension-free techniques as an outpatient procedure under local anesthesia. Prior to this, surgeons only used mesh for large or recurrent hernias, or when they thought it was absolutely necessary. They believed the mesh was a "foreign body" and would increase the risk of infection. However, subsequent studies proved the superiority of mesh, and now surgeons use mesh in their procedures frequently

Laparoscopic Repair In laparoscopic surgery, your surgeon inserts a laparoscope (a thin instrument with a light source and magnifying lens) through a small incision in your abdomen. The laparoscope enables your surgeon to examine the hernia and place a mesh patch on the inside of your abdominal wall. This surgery is called posterior hernia repair. It differs from traditional mesh repairs (discussed above), in which the mesh is placed on the outside of the abdominal wall.


Diverticulitis is condition that stems from inflammation of diverticula. Diverticular disease is a very common today. Prevention of diverticular disease is through diets high in fiber, physical activity, and avoiding foods such as nuts, popcorn, and seeds. When uncomplicated diverticulitis forms, the treatment is antibiotics, a clear liquid diet and often times stool softeners.

After several attacks of uncomplicated diverticulitis, we would recommend an elective partial colectomy to prevent further attacks. In cases of complicated diverticulitis, hospitalization is often required with intravenous antibiotics. The goal is to cool down the inflammatory process, and hopefully perform an elective partial colectomy and avoid a colostomy. There are times when a colostomy cannot be avoided(i.e. free rupture, severe diverticulitis and peritonitis that doesn’t respond to antibiotics).

Walnut Creek Surgical Associates perform all the techniques for resection of diverticulitis including laparoscopic colectomy, and open techniques.

Gastroesophageal Reflux Disease / Hiatal Hernia

A hiatal hernia is a condition in which a small part of your stomach bulges through a hole in your diaphragm. This hole, called a “hiatus,” is a normal, anatomically correct opening that allows your esophagus to connect to your stomach.

The cause of a hiatal hernia is unknown, but weak supportive tissues are thought to play a role, according to the U.S. National Library of Medicine (NLM). The hernia itself can play a role in the development of acid reflux, or GERD.

Acid Reflux, or GERD, is condition when stomach juices back up into the esophagus which may be associated with injury to the lining of the esophagus.  Symptoms include heartburn, chronic cough, and voice changes.  Abnormal reflux may occur because of an abnormality of theprotective mechanism of the lower esophageal sphincter.  Injury to the lining of the esophagus can become cancer if untreated.   Medical treatment is with antacids.  However, surgical treatment using small 1cm incisions can be performed for those with incomplete control of reflux with medications, Barrett’s esophagus, and extraesophageal manifestations of reflux including respiratory manifestations, ear infections, and dental erosion.  This procedure is called Laparoscopic Nissen fundoplication.

Thyroid / Parathyroid Disease

Both the thyroid and parathyroid glands are endocrine glands. This means they make and secrete (release) hormones. Hormones are chemicals which can be released into the bloodstream. They act as messengers, affecting cells and tissues in distant parts of your body. Thyroid hormones affect the body’s metabolic rate and the levels of certain minerals in the blood. The hormone produced by the parathyroid also helps to control the amount of these essential minerals.

Wound Care

Wounds are injuries that break the skin or other body tissues. They include cuts, scrapes, scratches, and punctured skin. They often happen because of an accident, but surgery, sutures, and stitches also cause wounds. Minor wounds usually aren’t serious, but it is important to clean them. Serious and infected wounds may require first aid followed by a visit to your doctor. You should also seek attention if the wound is deep, you cannot close it yourself, you cannot stop the bleeding or get the dirt out, or it does not heal.

Other common types of injuries include

  • Bruises
  • Burns
  • Dislocations
  • Fractures
  • Sprains and strains

Perirectal Disease / Hemorrhoids

Hemorrhoids (HEM-uh-roids), also called piles, are swollen and inflamed veins in your anus and lower rectum. Hemorrhoids may result from straining during bowel movements or from the increased pressure on these veins during pregnancy, among other causes. Hemorrhoids may be located inside the rectum (internal hemorrhoids), or they may develop under the skin around the anus (external hemorrhoids).
