While it is less painful and has a quicker recovery rate than conventional surgery, a systematic Review of the research shows that it is associated with a higher risk that the haemorrhoids will return or prolapsed compared to the ‘gold standard’ “Milligan-Morgan” technique of open haemorrhoidectomy.
Haemorrhoids are a common form of anorectal disorder, affecting around half of the population at some point in their lives. When they are severe, the person may be offered surgery. Conventional surgery is effective, but is associated with complications such as urinary retention, haemorrhage and pain. The newer Circular stapled technique reduces the patient’s pain, and initial reports suggested that it was preferred by patients. It was also found to work well in day-case surgery, which makes it economical to perform.
By gathering together all data from randomised trials, Cochrane Review Authors found that haemorrhoids recurred in 23 out of 269 patients who had staples, compared with 4 out of 268 who had conventional surgery. They also found a greater number of prolapses after one year and after five years in the stapled group.
“Patients should be informed of the risks when being offered stapled technique, particularly if they are worried about the chance of recurrence or prolapse,” says lead researcher Dr Shiva Jayaraman who works in the Department of Surgery at the University of Western Ontario, London, Canada.
The Review does confirm, though, that both methods are safe and serious complications are rare with either technique.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
