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: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
