Delaying surgery for hernia repair a safe option

18.01.2006


Men who delay surgical repair of a hernia until the hernia becomes uncomfortable fare as well those who undergo immediate surgery, according to a study at five North American medical centers.



In the study, published in the Jan. 18 issue of JAMA, a journal of the American Medical Association, 720 men with inguinal hernia (a small part of the large or small intestine protruding into the groin) were randomly assigned to either "watchful waiting" or standard hernia repair surgery and followed up for two to 4.5 years.

In an earlier study, the researchers had compared non-invasive laparoscopic hernia operations with open procedures. "But there are a lot of men walking around with hernias who say, ’If it’s not bothering me, I won’t bother it,’" said Dr. Olga Jonasson, professor of surgery at the University of Illinois at Chicago, who initiated the study. "We wanted to know if it was safe to delay surgery altogether."


Of the 364 men assigned to watchful waiting, 23 percent later chose to have surgery, usually because of increased pain. Seventeen percent of the 356 men assigned to surgery chose instead to cross over into watchful waiting. Waiting did not increase the rate of complications from surgery in those patients who eventually had it, and the rate of complications from hernias left unrepaired was even lower.

After two years, the same proportion of men in each group reported developing pain great enough to interfere with everyday activities, but both groups overall reported less pain at the end of the two years. Patients who received surgical repair reported significantly greater improvement in their ability to perform a range of everyday activities.

The authors conclude that a strategy of watchful waiting is "a safe and acceptable option" for men whose hernias are not causing discomfort that interferes with their day-to-day activities. Hernia complications occur only rarely, and patients who develop symptoms have no greater risk of operative complications than those undergoing preventative hernia repair.

Because the risk of complication increases with the length of time a hernia is present and is more common in the elderly, the researchers established a voluntary long-term registry for the clinical trial participants to access the occurrence of hernia complications and recurrences annually.

Other authors on the study include Dr. Robert Fitzgibbons Jr. of Creighton University; Dr. Jon Thompson of the Omaha VA Medical Center; Anita Giobbie-Hurder, Domenic J. Reda and Jia Wang of the VA Cooperative Studies Program in Hines, Ill.; James Gibbs, Dorothy Dunlop and Martin McCarthy Jr. of Northwestern University; Dr. Leigh Neumayer of the University of Utah; Dr. Jeffrey Barkun of McGill University; Dr. James Hoehn of Marshfield University; Drs. Joseph Murphy and George Sarosi Jr. of the Dallas VA Medical Center; and Dr. William Syme of the University of Nebraska, Omaha.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
