CUSA during liver resection

Its tip vibrates to fragment selected soft tissue, while irrigation and suction clear the operative field. This lets the surgeon identify blood vessels and bile ducts as the liver is divided, then seal, clip or tie them as appropriate.

Liver resection removes a planned portion of the liver containing a tumour or other diseased tissue. It may be considered for primary liver cancer or liver metastases, including some that originated in the bowel. CUSA is one option for the tissue-division stage; it is not a separate cancer treatment.

The surgeon may instead use or combine other dissection and vessel-sealing instruments. Tumour position, nearby vessels, liver condition, the planned open or minimally invasive approach, and the team's experience all influence the choice. Use of CUSA does not by itself determine whether a tumour can be completely removed.

Tell the surgical team about all medicines, supplements, allergies, previous abdominal operations and any heart, lung or liver problems. Follow individual instructions about eating, drinking and medicines before the operation; blood-thinning medicines require a plan rather than an unplanned stop.

After surgery, breathing exercises, pain control and gradual movement support recovery. The team will monitor the wound, liver function and signs of bleeding, infection or bile leakage. Follow the discharge advice on lifting, driving, wound care and returning to food and activity.

Contact the surgical team urgently for fever, worsening abdominal pain, an increasingly swollen abdomen, repeated vomiting, new jaundice, dark urine, pale stools, wound redness, pus, or fluid leaking from the wound. These findings can signal a complication that needs assessment.

Call emergency services for severe breathlessness, chest pain, collapse, confusion or heavy bleeding. New calf swelling or pain also requires prompt medical advice because it can accompany a blood clot.

Ask which part of the liver is planned for removal, how close the tumour lies to major vessels or bile ducts, which instruments may be used, and whether the approach could change during surgery. Clarify the expected hospital recovery, pathology review, follow-up imaging and whom to contact after discharge.
