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.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
