Bern’s surgical procedure for brain tumours a world leader

03.11.2015

A safety concept for removing brain tumours developed at the Inselspital leads to the best results for patients anywhere in the world, in honour of which it was awarded a prize at this year’s European Congress of Neurosurgery in Madrid.

Operations close to the brain’s motor centres are common (one in three brain tumours) and risky. If the surgeon has to remove a tumour from this area, incidental damage to motor pathways risks causing the patient to lose the use of an arm or leg. In order to prevent this, in 2014 neurosurgeons at the Inselspital in Bern developed a new safety instrument – the first of its kind in the world – which enables surgeons to operate near motor pathways or centres without endangering the safety of the operation.

Long-term study proves patient safety

Neurosurgeons in Bern have already used this method to operate on more than 200 patients, 182 of whom were included in a long-term study. This study showed that the surgical instrument permits enables tumours to be removed from areas close to the brain’s motor centres and pathways at low risk, significantly reducing the chance of long-term paralysis.

More specifically, the rate of permanent restrictions in mobility after the operations conducted in Bern was just 3%, one of the lowest in the world. The procedure also excelled at an international level, with Dr Kathleen Seidel and Professor Andreas Raabe receiving the prize for the best paper at the annual meeting of the European Association of Neurosurgical Societies in Madrid on 21 October.

“Our experiences from a large number of operations led us to develop this new instrument, which has transformed tumour surgery in this critical region,” says Professor Andreas Raabe, Physician-in-Chief of Neurosurgery. “We are very honoured to receive this award, as it reflects the outstanding results we have achieved in brain tumour surgery in Bern with our new hybrid probe.”

Bern’s hybrid probe soon to be used worldwide

The new surgical instrument can suction out the tumour tissue while stimulating the motor centres with an electrical radar, which tells the surgeon how close they are to these areas. In order to alert him or her to potential dangers, it uses acoustic signals similar to those found in electronic parking aids. The instrument therefore allows surgeons to operate while receiving constant feedback on their position, resulting in considerable improvements to patient safety.

Study author Dr Kathleen Siedel explains the instrument’s practical benefits: “Knowing exactly how close you are to a motor pathway leads to a significant reduction in surgical risk.”

Neuroscientists at the Inselspital in Bern have dedicated years of their work to improving brain tumour surgery. They teamed up with the German company Inomed to develop the hybrid probe, which can create a risk map in real time. This safe surgical instrument has now been approved by the medical authorities and will soon be in use all around the world.

Im Focus: Data storage using individual molecules

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.

Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...

Im Focus: Data use draining your battery? Tiny device to speed up memory while also saving power

The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.

Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

Im Focus: Lethal combination: Drug cocktail turns off the juice to cancer cells

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

Im Focus: New Foldable Drone Flies through Narrow Holes in Rescue Missions

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
