Description

Formerly Lakes DHB General Surgery

Lakes provides acute and elective surgical services at Rotorua and Taupō hospital sites. 

Acute services are provided 24 hours a day, 7 days a week and range from minor injuries/illness to major trauma. Elective services are provided five days per week and incorporate patient care in inpatient, day patient, and outpatient environments.

Day Stay Unit

Day Stay Unit is our point of entry for elective surgical patients.  The unit has 10 beds and 10 La-Z-Boy chairs and is currently open from 7.00am - 5.30pm.  As patients arrive they are assessed and prepared for their surgery.

Surgical Unit

The Surgical Unit cares for acute and elective surgical patients requiring general surgery procedures/care as well as acute urology, gynaecology, ophthalmology and ENT patients who may require at least one overnight stay.

Most patients in the Unit undergo surgery, but some are managed conservatively.  There are 25 beds in the Surgical Unit.  

Where to find us: see the Rotorua Hospital map here.

The General Surgery team are based at Rotorua Hospital but provide visiting services to Taupō Hospital.

 

What is General Surgery?

The role of the General Surgical Department varies from hospital to hospital, but in broad terms general surgery can be said to deal with a wide range of conditions within the abdomen, breast, neck, skin and, in many hospitals, vascular (blood vessel) system.

While the name would suggest that the focus of general surgery is to perform operations, often this is not the case. Many patients are referred to surgeons with conditions that do not need surgical procedures, but merely require counselling or medical treatment.

What is Vascular Surgery?

Vascular surgery is the branch of surgery that involves the diagnosis and treatment of disorders of the vessels that carry blood away from (arteries) and back to (veins) your heart.

Vascular disorders include blockages and narrowings of the vessels, abnormal swellings of the vessels (aneurysm) or vessel malfunctions. The disease processes involved in vascular disorders often involve other body systems and your treatment may therefore require the combined efforts of other medical specialists such as radiologists and general physicians.

Consultants

Referral Expectations

When you come to your appointment, your surgeon will ask questions about your illness and examine you to try to determine or confirm the diagnosis. This process may also require a number of tests (e.g. blood tests, x-rays, scans etc). Sometimes this can all be done during one visit, but for some conditions this will take several follow-up appointments. Occasionally some tests are arranged even before your appointment to try to speed up the process.

Once a diagnosis has been made, your surgeon will discuss treatment with you. In some instances this will mean surgery, while other cases can be managed with medication and advice. If surgery is advised, the steps involved in the surgical process and the likely outcome are usually discussed with you at this time.

Procedures / Treatments

Skin Disorders

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.

Endocrine Disorders

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.

Breast Disorders

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.

Gastrointestinal Disorders

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.

Gallstones

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.

Hernias

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. Hernia operations are very common and may be performed either with a standard open operation or laparoscopically (keyhole surgery).

Vascular Disorders

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.

Aortic Aneurysm

This is the dilatation or ballooning of a section of the aorta which is the main artery coming out of the heart. An aneurysm usually occurs because of an underlying weakness in the wall of the aorta at that point. Very often you will not have any symptoms from the aneurysm and it may only be discovered through a chest x-ray or CT scan. Most aneurysms found do not require surgery at the time of finding or in the future. However they should be monitored by scans to see if they are enlarging. If you have an aneurysm it is important that you do not smoke and your blood pressure should be monitored by your GP. If you have high blood pressure this needs to be well controlled. If one of your close family members (mother, father, or brother or sister) has been diagnosed with an aneurysm then you should discuss with your GP whether you should have a scan. This will depend on a number of factors that your GP can go over with you. Surgery may be offered depending on the size of the aneurysm or the rate of change in the size as seen on a scan. The pros and cons of surgery will be discussed with you by the vascular surgeon. If the aneurysm begins to get larger or leak, you may experience chest or back pain. If you have a known aneurysm and you experience these symptoms, you should seek urgent medical advice.

Carotid Artery Disease

You have two carotid arteries, one on either side of your neck, that supply blood to your brain. Carotid artery disease occurs if these arteries become narrowed due to atherosclerosis (a build up of fat and cholesterol deposits on the inner walls of the vessels). If a clot forms in one of the carotid arteries and reduces or stops the flow of blood to part of your brain, it may cause a stroke. You have an increased risk of developing carotid artery disease if you: · have a family history of atherosclerosis · smoke · have high blood pressure (hypertension) · have diabetes · have coronary artery disease. Treatment may involve lifestyle changes e.g. stopping smoking, exercising more, dietary changes and/or medication. If there is severe narrowing of the arteries, treatment may involve surgery.

Peripheral Arterial Disease

Peripheral arterial disease refers to the narrowing of arteries outside the heart and brain, usually as 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 target organs or tissues is reduced. The arteries commonly affected are those carrying blood to the kidneys, stomach, arms and legs. Peripheral arterial disease often appears first in your legs, with the most common symptom being dull, cramping leg pain that occurs when exercising but stops when you stand still. This is known as "intermittent claudication". Treatment for peripheral arterial disease may involve medication and/or surgery.

Varicose Veins

These are bulging veins that lie just beneath the skin (superficial veins). They occur when the walls of a vein are weak or damaged or if the valves in the vein that normally stop the blood from flowing backwards are impaired, resulting in pooling of the blood and stretched veins. Besides being unattractive, varicose veins can be painful and cause inflammation or ulceration. The following different types of surgery are available if varicose veins require treatment: Sclerotherapy – a tiny needle is used to inject a chemical solution into the vein that causes the vein to collapse. This approach is recommended for small varicose veins or spider veins that typically appear on the upper legs. You will need to wear elastic bandages or stockings over the treated area for some time after surgery. Vein stripping – the varicose veins are cut out and the veins that branch off them are tied off. The cuts (incisions) made in the skin are closed with sutures. You will need to wear elastic bandages or stockings over the treated area for some time after surgery. This procedure requires anaesthesia. Phlebectomy – small cuts (incisions) are made in the leg and the varicose veins are pulled out with a tiny hook-like instrument. The cuts are closed with tape rather than sutures and, once healed, are almost invisible. You will need to wear elastic bandages or stockings over the treated area for some time after surgery.

Hyperhidrosis

Hyperhidrosis is excessive sweating that may occur over the entire body or only in certain parts, most commonly the face, underarms, palms of the hands and soles of the feet. It may also refer to severe facial blushing. This condition is caused by overactivity of the nerves that carry messages to the affected sweat glands. These nerves are part of the 'sympathetic' nervous system, which means that they are 'involuntary' or not under our conscious control. Treatment may be with medication or, for facial and palm sweating, may involve a surgical procedure known as Endoscopic Thoracic Sympathectomy (ETS). Surgery is usually only offered if medication has failed and the sweating interferes with your daily functioning. The surgery is a minimally invasive procedure (it does not require a large incision or cut to be made) and involves interrupting the nerves that supply the sweat glands.

Ulcers

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.

Gastroscopy

This is a procedure which allows the doctor to see inside your oesophagus, stomach, and the first part of the small intestine (duodenum) and examine the lining directly. What to expect The gastroscope is a plastic-coated tube about as thick as a ballpoint pen and is flexible. It has a tiny camera attached that sends images to a viewing screen. During the test you will swallow the tube but the back of your throat will be sprayed with anaesthetic so you don’t feel this. You will be offered a sedative (medicine that will make you sleepy but is not a general anaesthetic) as well. Not all patients require sedation for this procedure. If the doctor sees any abnormalities they can take a biopsy (a small piece of tissue) to send to the laboratory for testing. This is not a painful procedure and will be performed at the day stay unit in a theatre suite (operating room) by a specialist doctor with nurses assisting. Complications from this procedure are very rare but can occur. They include: bleeding after a biopsy, if performed an allergic reaction to the sedative or throat spray perforation (tearing) of the stomach with the instrument (this is a serious but extremely rare complication). Before the procedure You will be asked not to eat anything from midnight the night before and not to take any of your medications on the day of the procedure. After the procedure You will stay in the day stay unit until the sedation has worn off which usually takes 1-2 hours. You will be given something to eat or drink before you go home. If you have been sedated, you are not to drive until the following day. If biopsies are taken these will be sent for analysis and results are available within 2-3 weeks. A report and copies of these are sent to your GP.

Colonoscopy

This is a procedure which allows the doctor to see inside your large bowel and examine the surfaces directly and take biopsies (samples of tissue) if needed. Treatment of conditions can also be undertaken. What to expect The colonoscope is a flexible plastic-coated tube a little thicker than a ballpoint pen which has a tiny camera attached that sends images to a viewing screen. You will be given a sedative (medicine that will make you sleepy but is not a general anaesthetic). The tube is passed into the rectum (bottom) and gently moved along the large bowel. The procedure takes from 10 minutes to 1 hour and your oxygen levels and heart rhythm are monitored throughout. The procedure is performed in a day stay operating theatre. Before the procedure You will need to follow a special diet and take some laxatives (medicine to make you go to the toilet) over the days leading up to the test. Risks of a colonoscopy are rare but include: bleeding if a biopsy is performed allergic reaction to the sedative perforation (tearing) of the bowel wall.
