Abstract

The presence of a malignancy of the upper aerodigestive tract introduces the potential for iatrogenic complications additional to those usually associated with percutaneous endoscopic gastrostomy. Specifically, seeding of tumour from the upper aerodigestive tract creating abdominal wall metastases, and airway obstruction due to tumour directly occluding the airway when a patient is sedated for percutaneous endoscopic gastrostomy. We report an audit of our experience of gastrostomy placement for patients under going treatment for head and neck cancer in our institution from September 2003 to October 2006. Of 33 patients who had percutaneous endoscopic gastrostomy insertion under sedation in the first cycle of the audit, two (6%) experienced major airway complications resulting in one fatality. A tumour assessment protocol was introduced. In the second cycle, 96 patients had percutaneous endoscopic gastrostomies, of whom 16 (13%) underwent gastrostomy insertion under general anaesthetic and five (4.5%) under radiological guidance. No patients had airway complications or abdominal wall metastases. A formal tumour assessment protocol eliminated airway obstruction as a complication of percutaneous endoscopic gastrostomy insertion and may reduce the potential for abdominal wall metastases at the gastrostomy site when using the pull technique.
