MDCT accurately locates bowel perforation avoiding need for exploratory surgery

25.01.2007
Multidetector CT (MDCT) without the use of contrast media can show the precise site of a bowel perforation, avoiding the need for surgeons to do exploratory surgery of the patient's gastrointestinal tract to locate the problem, a new study shows.

In the past, the best way to find a perforation in the bowel was to administer oral or rectal contrast media then watch to see if and where the contrast media leaked from the bowel, said Bernard Hainaux, MD of Centre Hospitalier Universitaire St.-Pierre in Brussels, Belgium. Dr. Hainaux was lead author of the study. If there was a leak, then that was assumed to be the site of the perforation, however, this method was not very sensitive , he said. In addition, it is often difficult to administer oral or rectal contrast media to a patient with acute abdominal pain or with penetrating injuries, Dr. Hainaux said.

The study found that MDCT without contrast media could accurately show the site of bowel perforation in 73 of 85 patients, Dr. Hainaux said. Radiologists should look for three things on the MDCT image – gas bubbles near the bowel wall, a defect in the bowel wall and thickening of the bowel wall—they all point to the location of the bowel perforation, he added.

It is very beneficial for surgeons to know in advance where the bowel is perforated, Dr. Hainaux said. "MDCT allows us to quickly image the patient, then reformat the images so we can look at them from many different angles, making this technique particularly suitable for the assessment of abdominal abnormalities," he said.

Im Focus: Optical Nanoscope Allows Imaging of Quantum Dots

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.

Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...

Im Focus: Artificial agent designs quantum experiments

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

Im Focus: The first precise measurement of a single molecule's effective charge

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.

Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...

Im Focus: Paradigm shift in Paris: Encouraging an holistic view of laser machining

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.

No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
