General surgery covers a wide spectrum of surgical conditions, including abdominal, skin and soft tissues, gastrointestinal, vascular and endocrine systems.  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 general surgeons with conditions that do not need surgical procedures, but merely require counselling or medical treatment.

The most common indication for gallbladder surgery is symptomatic gallstones. Gallstones are stones formed within the gallbladder out of the components of bile. Laparoscopic cholecystectomy is the surgical removal of the gallbladder using a laparoscope (a tube like instrument). This is commonly known as keyhole surgery and is safe and effective for most patients who have symptoms from gallstones. There are usually three or four small cuts (incisions) made in the abdomen, however the number of the cuts and their positions may vary between patients.

Most patients who require a liver resection have metastases from a colorectal (bowel) cancer.  Less commonly other secondary cancers from neuroendocrine tumors (like carcinoid), renal cancer, breast or melanoma are resected.  The most common primary liver cancer that is resected is hepatocellular carcinoma (HCC or Hepatoma). This is a cancer that originates in liver cells (primary), and is usually associated with underlying chronic liver disease. Primary cancers of the bile ducts, cholangiocarcinoma, are less commonly resected.  There are a number of benign lesions that occur in the liver… READ MORE

Gastrointestinal surgery is the branch of surgery that intervenes to treat or improve the prognosis of pathologies affecting the digestive system.

This includes conditions that affect the stomach, small and large bowel as well as the solid intra-abdominal organs; pancreas and liver.

Associate Professor, Dr. Adam Bartlett

The pressure from inside the abdomen then pushes the lining of the abdominal wall, the peritoneum, out through this area of weakness, leading to a bulge under the skin. The hernia sac may start as a small lump, which disappears when the patient is lying down, and may be only apparent when standing or straining (coughing). Hernias are not always painful, they can be found incidentally. … READ MORE

Laparoscopy is a surgical procedure involving the use of small instruments introduced through keyholes to operate on organs inside the abdomen. It’s a low-risk, minimally invasive procedure that requires only small incisions.

Laparoscopy is often used to identify and diagnose the source of pelvic or abdominal pain. It’s usually performed when non-invasive methods are unable to help with diagnosis.  It is also used as a means to perform a number of operations, including cholecystectomy, appendicectomy, hernia repair, colectomy, appendectomy, and resection of solid organs (pancreas, liver, spleen).

Associate Professor, Dr. Adam Bartlett

Pancreas is a vital gland, located behind the stomach just below the liver. It produces several digestive enzymes (exocrine function) and also plays a vital role in maintaining the blood glucose levels (endocrine function).

Any disease or injury to the pancreas may cause several problems. Pancreatic surgery comprises a wide range of surgical procedures performed on the pancreas. Most operations involve a resection or removal of the diseased portion of the pancreas. … READ MORE

Allergies, also known as allergic diseases, are a number of conditions caused by hypersensitivity of the immune system to typically harmless substances in the environment.

An allergist diagnoses and treats diseases including hay fever, food allergies, atopic dermatitis, allergic asthma, and anaphylaxis.

Immunology is the study of the immune system and is a very important branch of the medical and biological sciences. The immune system protects us from infection through various lines of defence. If the immune system is not functioning as it should, it can result in disease, such as autoimmunity, allergy and cancer.

Clinical immunologists are clinicians who focus on the diagnosis and management of diseases of the immune system, such as autoimmune diseases, allergies and immunodeficiency.

Dr. Pete Storey


Nephrology is the subspecialty of internal medicine that focuses on the diagnosis and treatment of diseases of the kidney. Because the kidney performs so many critical functions, nephrologists maintain expertise in primary kidney disorders, but also the management of the systemic consequences of kidney dysfunction. Although the prevention and identification and management of early kidney disease is a large part of general internal medicine practice, nephrologists are usually called upon to assist and manage more complex or advanced nephrologic disorders.

Perioperative medicine is the multidisciplinary, integrated care of patients from the moment surgery is contemplated through to recovery. It involves:

  • Preoperative evaluation.
  • Risk assessment and preparation.
  • Intraoperative care.
  • Postoperative care (including monitoring, rehabilitation and post-discharge).
  • Communication and handover to primary care or referrer.
  • Coordination of personnel and systems.
  • Shared decision making.

Perioperative medicine aims to facilitate effective communication with the patient and their family to ensure that surgical outcomes align with their expectations and wishes.

The perioperative specialist will help patients navigate the healthcare system and co-ordinate their care by different clinicians and sub-specialties through shared decision making. The goal is to improve the patient experience, reduce postoperative complications, reduce inpatient hospital days and reduce early re-admissions following surgery.
