PATIENTS have voiced frustration over delays to operations at a sewage-hit brain injury unit in Glasgow.

The Evening Times revealed earlier this month that all elective surgery had been cancelled at the Institute of Neurosciences at the Queen Elizabeth University Hospital campus in Glasgow.

It followed a series of incidents which saw raw sewage leak from the ageing building into operating theatres and recovery rooms.

A spokeswoman for NHS Greater Glasgow and Clyde said the situation "remains unchanged."

She said experts were looking at the entire building to try to find a permanent solution to the problem and elective cases were being re-scheduled "based on clinical priority."

Emergency and urgent surgery is still being carried out at the unit in two theatres.

Waste pipes in wards above the recovery area at the institute burst on February 26, causing the contents to leak into the recovery area, the second incident in a matter of weeks.

The unit was hit by an earlier incident in September last year.

Air quality tests have been carried out at the unit in the past couple of weeks.

Meanwhile, patients waiting for surgery have voiced frustration over a lack of information from the hospital.

One patient, who asked not to be named, said her surgery was originally scheduled for early March but she has yet to receive an alternative date for her procedure.

She said: "I have been calling every week for an update. I was told that consultants are waiting for advice from management and I don't have any date for my surgery.

"I'm in so much pain."

The unit was not upgraded when the £842 million new hospital was built and its operating theatres are due to be replaced next year.

A spokeswoman for NHSGGC said: "We are working on re-scheduling elective cases based on clinical priority.

"The surveys are looking at the entire building to find a permanent solution to the issue.
