Treatments, operations and tests

Appendix removal

An appendectomy (sometimes called appendisectomy or appendicectomy) is the surgical removal of the vermiform appendix. This procedure is normally performed as an emergency procedure, when the patient is suffering from acute appendicitis. In the absence of surgical facilities, intravenous antibiotics are used to delay or avoid the onset of sepsis; it is now recognized that many cases will resolve when treated non-operatively.

Endoscopy (Upper GI)

An upper gastrointestinal endoscopy uses a long endoscope to see the lining of the upper GI tract. This is used to identify the cause of many symptoms, from persistent heartburn to unexplained weight loss. There are a wide range of diseases that may be diagnosed by an Upper GI Endoscopy.

Gall bladder removal (Laparoscopic)

Gall bladder removal (cholecystectomy) surgery is usually performed laparoscopically (keyhole), using a laparoscope. The surgeon removes your gall bladder with the aid of a small camera which is inserted into the abdomen via one of a number of small incisions in the abdomen. It is now a relatively common procedure which requires only a short time in hospital.

Hernia repair (femoral)

Femoral hernias occur just below the inguinal ligament, when abdominal contents pass through a naturally occurring weakness called the femoral canal. Femoral hernias are a relatively uncommon type, accounting for only 3% of all hernias. While femoral hernias can occur in both males and females, almost all of them develop in women because of the wider bone structure of the female pelvis. Femoral hernias are more common in adults than in children. Those that do occur in children are more likely to be associated with a connective tissue disorder or with conditions that increase intra-abdominal pressure.

Hernia repair (inguinal)

A hernia is a weakness in the stomach or abdominal wall. There are various forms of treatment - open hernia surgery using a mesh to repair the weakness, and keyhole surgery which may enable you to return to normal activities sooner.

Hernia repair (Laparocscopic Incisional)

A hernia occurs when the abdominal muscle weakens, resulting in a bulge or tear through which tissue can be pressed and cause extreme pain. Laparoscopic techniques require a small incision and the insertion of a camera/tool to repair the hernia through surgical staples and patches. While the incision is minimal and generally performed as an outpatient procedure it requires a general anaesthetic.

Hernia repair (umbilical)

The hernia pouch or sac is the lining of the inside of the tummy wall. It pushes through the weakness at the tummy button. The sac has a fatty covering and inside there may be bowel or fatty tissue called omentum. The sac steadily gets larger and can be painful. The bowel and omentum may get stuck in the sac. Their blood supply can be cut off and the bowel and omentum can strangulate and die. This causes vomiting, great pain and is very serious. Umbilical hernias are very common and easily treated, particularly when small. If treated when they are small, this will prevent strangulation and make the strongest repair.

Hernia Repair - Groin (Inguinal) - Open surgery

A hernia occurs when the abdominal muscle weakens, resulting in a bulge or tear through which tissue can be pressed and cause extreme pain. Surgical intervention uses a single long incision to allow access to the site of the hernia where the bulge can be removed or pushed back into the abdominal cavity and the muscle walls repaired with stitches or patches depending on the size of the rupture.

Oesophagus and stomach examination by endoscope (gastroscopy)

Gastroscopy is an examination of the upper digestive tract (the oesophagus, stomach and duodenum) using an endoscope — a long, thin, flexible tube containing a camera and a light — to view the lining of these organs.

Spleen removal

A splenectomy is a surgical procedure that partially or completely removes the spleen. Open surgery is performed in trauma cases or if the spleen is enlarged. Either method is major surgery and is performed under general anesthesia. The spleen is located and disconnected from its arteries. The ligaments holding the spleen in place are dissected and the organ is removed. In some cases, one or more accessory spleens are discovered and also removed during surgery. The incisions are closed and when indicated, a drain is left. If necessary, tissue samples are sent to a laboratory for analysis.
