GI Cancer Surgery
Comprehensive Surgical Care for GI Cancers
Surgery is the main treatment for most cancers of the stomach, colon and rectum. We offer complete cancer surgery with laparoscopic and robotic options, planned together with oncologists.
About GI Cancer Surgery
Gastrointestinal (GI) cancers include cancers of the oesophagus, stomach, small intestine, colon and rectum. The aim of surgery is to remove the tumour completely along with the surrounding lymph nodes.
Every case is planned with medical and radiation oncologists, so surgery is combined with chemotherapy or radiotherapy where needed for the best chance of cure.

Frequently Asked Questions
What are the warning signs of GI cancer?
Warning signs include persistent indigestion, difficulty swallowing, blood in the stool, a change in bowel habits, unexplained weight loss, anaemia and abdominal pain. These should be checked by a specialist.
Can GI cancers be treated with keyhole surgery?
Yes. Many stomach, colon and rectal cancers can be removed with laparoscopic or robotic surgery, which means smaller cuts, less pain and a faster recovery without compromising the cancer operation.
Will I need chemotherapy as well?
It depends on the type and stage of cancer. Some patients need chemotherapy or radiotherapy before or after surgery. The plan is made together with the oncology team.
Will I need a stoma after rectal cancer surgery?
Many patients can have sphincter-saving surgery. A temporary stoma is sometimes made to protect the join and is usually reversed later. A permanent stoma is needed only for very low tumours.
