Gastrointestinal stromal tumour (GIST) surgery
Expert care for rare stomach and bowel tumours
At Auckland Laparoscopic Surgery, we understand how unsettling it can be to receive a diagnosis involving a rare tumour. That’s why we’re here to provide not only expert care, but also kind, clear guidance through every step of your journey. Our approach is safe, compassionate, and grounded in the latest medical evidence.
What is a GIST?
A Gastrointestinal Stromal Tumour (GIST) is a rare type of tumour that begins in the connective tissue of the gastrointestinal (GI) tract, most commonly in the stomach or small intestine.
GISTs may be benign (non-cancerous) or malignant (cancerous) and typically begin in specialised cells in the gut wall that help coordinate movement and digestion.
These tumours can affect both men and women, usually over the age of 40. Some are discovered incidentally, while others cause symptoms such as abdominal pain, bleeding, anaemia, or a feeling of fullness.
Common symptoms of a GIST
While some GISTs are discovered incidentally during investigations for other conditions, symptoms may include:
- Abdominal discomfort or swelling
- Gastrointestinal bleeding (black or bloody stools)
- Anaemia (low red blood cell count)
- Nausea or early satiety (feeling full quickly)
- Unexplained weight loss
If you are experiencing any of these symptoms, please don’t ignore them. It’s important to seek medical attention promptly.
How is a GIST diagnosed?
Diagnosis usually involves a combination of:
- Endoscopy – A camera test to view the stomach or bowel lining
- CT scan or MRI – To visualise the tumour and surrounding organs
- Biopsy – A sample of the tumour may be taken to confirm the diagnosis
Treatment options for GIST
Surgery – the primary treatment
In most cases, surgical removal of the tumour is the most effective treatment, especially if the GIST hasn’t spread.
At Auckland Laparoscopic Surgery, we specialise in minimally invasive GIST surgery, which offers the benefits of:
- Smaller incisions
- Reduced pain
- Quicker recovery
- Shorter hospital stays
Depending on the tumour’s size and location, different types of surgery may be recommended, such as:
- Laparoscopic wedge resection (removal of the tumour with a rim of healthy tissue)
- Laparoscopic transgastric resection (removal of the tumour from within the stomach, with a rim of healthy tissue, when the tumour is too large for endoscopic removal)
- Segmental bowel resection (removal of part of the bowel if the tumour is in the small intestine)
In some cases, open surgery may be required for larger or more complex tumours.
Targeted therapy
If a GIST cannot be removed surgically, or if it has spread (metastasised), targeted medication such as Imatinib (Glivec) may be used to shrink or control the tumour. This is also sometimes given after surgery (adjuvant therapy) to reduce the risk of recurrence.
Pros and cons of GIST surgery
- Offers a potential cure for localised tumours
- Can significantly reduce or eliminate symptoms
- Minimally invasive techniques promote faster recovery
- May prevent future complications such as bleeding or obstruction
- Risk of recurrence, especially for larger or aggressive tumours
- Surgery may not be possible if the tumour has spread
- Postoperative monitoring and sometimes long-term medication are needed
- Possible complications include bleeding, infection, or damage to surrounding organs (though rare)
