What are the risks of this specific procedure?

There are risks and complications with this procedure.
They include but are not limited to the following:

General risks:

  • Infection can occur, requiring antibiotics and further treatment.
  • Bleeding could occur and may require a return to the operating room. Bleeding is more common if you have been taking blood thinning drugs such as Warfarin, Asprin, Clopidogrel (Plavix or Iscover) or Dipyridamole (Persantin or Asasantin).
  • Small areas of the lung can collapse, increasing the risk of chest infection. This may need antibiotics and physiotherapy.
  • Increased risk in obese people of wound infection, chest infection, heart and lung complications, and thrombosis.
  • Heart attack or stroke could occur due to the strain on the heart.
  • Blood clot in the leg (DVT) causing pain and swelling. In rare cases, part of the clot may break off and go to the lungs.
  • Death as a result of this procedure is possible.

Specific risks:

  • Heavy bleeding may occur from the biopsy site. This may require further surgery and possible blood transfusion
  • The bowel may perforate and further treatment may be necessary.
  • All of the tumour may not be able to be removed at one sitting and further surgery may be necessary.
  • Recurrence of the tumour which may require more extensive surgery.
  • Adhesions (bands of scar tissue) may form and cause a bowel obstruction. This can be a short term or a long term complication and may need further surgery.
  • Increased risk in smokers of wound and chest infections, heart and lung complications and thrombosis.
