After training as a general surgeon in Auckland I spent almost 2 years in Edinburgh gaining subspecialty expertise in hepato-biliary, pancreatic and gastro-oesophageal surgery.
On returning to NZ in 1992, I established the first HBP/Upper GI Unit in NZ in 1993 at Auckland City Hospital. During the 1990s I pioneered a number of laparoscopic surgeries and set up the Surgical Skills Training Centre.
As Professor of Surgery at the University of Auckland I have a research program and I am involved in surgical teaching and training.
My surgical practice encompasses the management of the following diseases.
- Pancreatic cancer (adenocarcinoma, neuroendocrine, other)
- Neoplastic cysts (mucinous, serous, IPMN)
- Acute pancreatitis
- Chronic pancreatitis
- Pancreatic pseudocysts
- Autoimmune pancreatitis
- Gallstone disease (biliary colic, acute cholecystitis, mucocoele)
- Gallbladder cancer (cholangiocarcinoma)
- Bile duct tumours
- Bile duct stones (choledocholithiasis, cholangitis)
- Choledochal cyst
- Post-cholecystectomy syndrome
- Gastro-oesophageal reflux (GORD, hiatus hernia, para-oesophageal hernia, revision)
- Achalasia and motility disorders
- Oesophageal cancer (adenocarcinoma, squamous cell carcinoma)
- Oesophageal perforation
- Oesophageal diverticulae
- Stomach cancer
- Gastrointestinal stromal tumour (GIST)
- Peptic ulcer disease
- Inguinal (groin) hernia
- Incisional hernia
- Ventral hernia
- Femoral hernia
Small Bowel and Appendiceal Disease
- Adhesive bowel obstruction
- Small bowel tumours
- Acute and chronic appendicitis
What is General Surgery?
The role of the general surgeon varies, but in broad terms general surgery can be said to deal with a wide range of conditions within the abdomen, breast, neck, skin and 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 Hepato-biliary and Pancreatic Surgery?
This is a sub-specialty of general surgery involving surgery of the liver, pancreas and biliary system. HPB surgeons help to diagnose and treat patients with conditions such as liver cancer (primary or secondary), pancreatic cancer, pancreatitis, bile duct cancer and gallstones.
What is Laparoscopic Surgery?
Laparoscopic (or keyhole) surgical procedures are performed through several small cuts (incisions) usually only 5 -10mm long, rather than through one large incision.
A long, narrow surgical telescope (laparoscope) that has a tiny camera and light source attached is inserted through one of the incisions so that the surgeon can view the inside of the body on a TV monitor.
The surgeon then passes specially designed surgical instruments through the other incisions and carries out the procedure using the TV monitor to guide the instruments.
Laparoscopic surgery is usually associated with less blood loss during surgery and less pain and scarring following surgery. In most cases, time spent in hospital is less and overall recovery time from the operation is less than with conventional open surgery.
