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 more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
