Skin conditions dealt with by general surgery include lumps, tumours 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.

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.

General surgery covers breast diseases including breast cancer. These conditions are often initially dealt with in a specialised breast clinic which is able to perform a number of investigations (e.g. mammography, ultrasound, needle biopsy) during the initial outpatient clinic visit.

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.

Disorders of the salivary glands may be dealt with by the general surgical department or the ENT (ORL) department depending on the local policy.

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.

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.

Vascular (blood vessel) disorders treated by general surgery include varicose veins, blockages and narrowings in the arteries or abnormal swellings of the arteries (aneurysm). The most common of these conditions facing the general surgeon is varicose veins. This occurs when veins in the legs and thighs become enlarged and twisted. This is often caused by the failure of the one-way valve system in the veins, in which case it can be treated surgically by removing the segments of veins containing the malfunctioning valves as well as those veins which are significantly dilated.
