A hernia exists where part of the abdominal wall is weakened, and the contents of the abdomen push through to the outside. This is most commonly seen in the groin area but can occur in other places. Surgical treatment is usually quite straightforward and involves returning the abdominal contents to the inside and then reinforcing the abdominal wall in some way. An inguinal hernia is caused by a connection between the scrotum and the abdomen (uncommonly a similar connection occurs in girls causing an inguinal hernia). The connection is present in all babies in the womb during development, but in most babies has closed over before birth. The connection allows some contents of the abdomen to pass down towards the scrotum causing a bulge in the groin. The bulge is often more noticeable when the baby cries. The bulge (or hernia) can usually be pushed back into the abdomen by gentle pressure when the baby is settled. Uncommonly the hernia cannot be pushed back (“reduced”), which can be a serious complication because the tissue trapped in the connection can become swollen and damaged. An inguinal hernia can be repaired with a simple operation. Your family doctor will have referred you to a children’s surgeon who is experienced in repairing inguinal hernias. An umbilical hernia is caused by a weakness in the muscles of the abdominal wall near the belly button or navel, which allows the contents of the abdomen to push through and form a bulge around the belly button. In most cases these hernias close by themselves before the age of 5 years, but if they are large or are causing problems, they may require surgery.

General surgery covers some disorders of the liver and biliary system. The most common of these is pain caused by gallstones. These are formed if the gallbladder is not working properly, and the standard treatment is to remove the gallbladder (cholecystectomy). This procedure is usually performed using a laparoscopic (keyhole) approach.

These are large, complex incisional hernias from previous abdominal surgeries. They require careful planning and multi-disciplinary surgical care.

These are due to chest wall injuries and deformities likely due to trauma. The ribs are realigned with titanium plates to ease pain, reduce deformity and improve breathing. Most are ACC related.

Removal of appendix due to inflammation. This can be simple or complex-acute or chronic.

Conditions of the gut dealt with by general surgery include disorders of the oesophagus, stomach, small bowel, large bowel and anus. These range from complex conditions such as ulceration or cancer in the bowel through to fairly minor conditions such as haemorrhoids. Many of the more major conditions such as bowel cancer will require surgery, or sometimes treatment with medication, chemotherapy or radiotherapy. Haemorrhoids are a condition where the veins under the lining of the anus are congested and enlarged. Less severe haemorrhoids can be managed with simple treatments such as injection or banding which can be performed in the clinic while larger ones will require surgery.

Skin conditions dealt with by paediatric surgeons include lumps, tumours, cysts and other lesions of the skin and underlying tissues. These are often fairly simple conditions that can be dealt with by performing minor operations under local anaesthetic (the area of skin being treated is numbed). Often these procedures are performed as outpatient or day case procedures.

Vascular ulcers are open wounds on the skin that do not heal or that keep coming back once they do heal. They occur because there is not enough blood being supplied to the skin to heal injuries that may be caused by minor trauma or pressure. Arterial or ischaemic ulcers are usually the result of atherosclerosis or "hardening of the arteries" (a build up of fatty deposits on the inner wall of arteries). When the arteries become narrowed, the flow of blood to the tissues is reduced. These ulcers are usually found on the toes and edge of the foot and are often very painful. Treatment for arterial ulcers may involve surgery. Venous or stasis ulcers occur when impaired blood flow in the veins causes pooling of blood in the legs. These ulcers are often associated with varicose veins. Venous ulcers are usually found on the lower leg between the knee and the ankle and the leg is often swollen and discoloured. Compression or pressure bandages are the main treatment for venous ulcers although surgery may be required in some patients.

Abnormalities of the endocrine system treated by general surgery include disorders of the pancreas and adrenal glands in the abdomen and the thyroid and parathyroid glands in the neck. These are often very complex conditions requiring extensive investigations. If surgery is required it is often quite complicated and will usually mean a stay in hospital for several days or even longer.
