Cancer Surgery
Our surgeons provide expert surgical treatment for oesophageal and gastric cancers using advanced laparoscopic and robotic techniques. Every patient receives personalised, multidisciplinary care from diagnosis through to recovery and beyond.
Cancers we treat
Our surgeons specialise in the surgical management of upper gastrointestinal cancers and pre-cancerous conditions, including:
Oesophageal Cancer
Cancer of the oesophagus (food pipe). May present with difficulty swallowing, weight loss, or chest pain. Early diagnosis and treatment are critical for the best outcomes.
Gastric (Stomach) Cancer
Cancer arising in the stomach lining. Symptoms may include persistent indigestion, unexplained weight loss, or abdominal discomfort. Treatment depends on stage and location.
Gastrointestinal Stromal Tumours (GIST)
A type of tumour that develops in the wall of the gastrointestinal tract. Often found incidentally and may require surgical removal depending on size and location.
Pre-cancerous Conditions
Conditions such as Barrett's oesophagus and gastric polyps that carry an increased risk of developing into cancer. Close monitoring and early intervention are important.
Our Treatment Approach
Our surgeons use the most advanced techniques available to achieve the best possible outcomes for every patient. The approach is tailored to each individual based on cancer type, stage, and overall health.
Oesophagectomy
Surgical removal of part or all of the oesophagus for oesophageal cancer. Can be performed using minimally invasive, robotic, or open techniques depending on the individual case.
- Minimally invasive and robotic approaches available
- Mr Kulasegaran performed New Zealand’s first robotic oesophagectomy
- Aims to achieve complete cancer removal with clear margins
- Reconstruction restores the ability to eat and swallow
Gastrectomy
Partial or total removal of the stomach for gastric cancer. The extent of surgery depends on the location and stage of the cancer.
- Laparoscopic and robotic techniques available
- Mr Kulasegaran performed New Zealand’s first robotic gastrectomy
- Subtotal or total gastrectomy depending on tumour location
- Lymph node dissection as appropriate
Staging Laparoscopy
A minimally invasive procedure to assess the extent of cancer spread before planning definitive treatment. Helps the multidisciplinary team determine the best treatment approach.
- Small keyhole incisions to inspect the abdominal cavity
- Identifies cancer spread not visible on imaging
- Guides treatment planning and avoids unnecessary major surgery
- Usually performed as a day procedure
Multidisciplinary Team (MDT) Care
Every cancer patient is discussed at a multidisciplinary team meeting involving surgeons, oncologists, radiologists, and other specialists to ensure the best treatment plan.
- Personalised treatment plan for every patient
- Coordinated care across surgical, medical, and radiation oncology
- Regular review throughout your treatment journey
- Access to the latest evidence-based treatment protocols
What to expect
Diagnosis and staging
Your surgeon will review all investigations and imaging. You may need additional tests including endoscopy, CT scans, PET scans, or staging laparoscopy to accurately stage your cancer and plan treatment.
Your treatment plan
Your case is discussed at a multidisciplinary team meeting. Treatment may involve surgery alone, or a combination of chemotherapy and surgery. Your surgeon will explain the recommended approach and answer all your questions.
Surgery and recovery
Our surgeons use the most advanced techniques available, including robotic surgery, to achieve the best outcomes with the fastest recovery. You will receive comprehensive support throughout your hospital stay and ongoing follow-up care.

Contact usFrequently asked questions
What happens after a cancer diagnosis?
After diagnosis, your case will be reviewed by our multidisciplinary team. We will arrange any additional investigations needed and develop a personalised treatment plan. We understand this is an anxious time and will keep you informed at every step.
Will I need chemotherapy as well as surgery?
This depends on the type and stage of your cancer. Many patients benefit from chemotherapy before and/or after surgery. Your treatment plan will be discussed with you in detail at your consultation.
How long will I be in hospital after cancer surgery?
Recovery time varies depending on the procedure. Oesophagectomy typically requires 7–10 days in hospital, while gastrectomy may require 5–7 days. Your surgeon will provide specific guidance based on your procedure.
Is robotic surgery available for cancer operations?
Yes. Mr Kulasegaran is a pioneer in robotic cancer surgery in New Zealand, having performed the country’s first robotic oesophagectomy and gastrectomy. Robotic surgery can offer benefits including reduced blood loss, less pain, and faster recovery.
What support is available during treatment?
You will have ongoing access to your surgeon, oncology team, specialist nurses, and dietitian support. We also provide guidance on nutrition, rehabilitation, and managing side effects throughout your treatment.
