22/05/2017For many years, cochlear implants have restored a sense of hearing in people with certain types of hearing loss. For surgeons, the implantation requires a precise attention to detail under the microscope. The results for the patients improve significantly with a more precise placement of the electrode array. The use of a surgical robot can increase the accuracy of the procedure.
11/05/2017It is not often that a fall saves someone's life. Helen Powell, 74, says that was the case for her. A computerized tomography scan that followed her fall revealed a cancerous brain tumor that led her to Mayo Clinic and surgery using first-in-the-world technology. Brain magnetic resonance elastography (MRE) imaging, showed the precise firmness of her tumor.
10/05/2017A computer-driven automated drill, similar to those used to machine auto parts, could play a pivotal role in future surgical procedures. The new machine can make one type of complex cranial surgery 50 times faster than standard procedures, decreasing from two hours to two and a half minutes.
25/04/2017Just as an athlete might work to build up stamina before a race, a person entering the hospital also can benefit from prepping the mind and body. Even minor adjustments to diet and mental health could help some individuals go home sooner - and, in turn, save hospitals and insurance companies money.
10/04/2017A surgical technique that sends electrical impulses to a specific area of the brain reduces the "tics," or involuntary movements and vocal outbursts, experienced by young adults with severe cases of Tourette syndrome, according to a new study led by investigators from NYU Langone Medical Center.
10/04/2017People with hip osteoarthritis often suffer from severe pain and only an endoprosthesis implantation can provide relief. This involves a major intervention and long-term rehabilitation because the implant requires the removal of a section of the thigh bone. The "MioHIP" research project looks for an elastic alternative.
21/03/2017People with spinal deformity also requiring a total hip replacement are at greater risk for dislocation or follow-up revision surgery, suggesting that these higher-risk patients may benefit from a more personalized approach to their surgeries to reduce the risk of poorer outcomes.
14/03/2017Invasive surgical techniques - cutting through the breastbone for open heart surgery or making a large incision to inspect an abdominal tumor - allow physicians to effectively treat disease but can lead to sometimes serious complications and dramatically slow healing for the patient.
10/03/2017Focused ultrasound can effectively destroy tumor cells. Until now, this method has only been used for organs such as the prostate and uterus. At the European Congress of Radiology, Fraunhofer researchers will present a method, developed as part of the TRANS-FUSIMO EU project, that enables focused ultrasound treatment of the liver, an organ that moves while breathing.
02/03/2017An approved international test to check whether people need open heart surgery could be sending twice as many people under the knife unnecessarily, at a cost of nearly £75m, research by the University of Leicester has suggested.
01/03/2017Genome data, MRI images, and blood test results – data collected in the medical sector is not only very heterogeneous but also extremely extensive. However, it is important to not only collect this data but to also utilize it. After all, processed, linked and analyzed data provides many opportunities in research, hospital management and ultimately also for the individual patient.
01/03/2017The OR is the centerpiece of every hospital and also the most expensive resource that should be used efficiently. Yet in reality, there are often delays when interventions are not intelligently scheduled and take place back-to-back. This is why the InnOPlan Research Consortium wants to make surgical device data usable and useful to improve the operating room planning process.
22/02/2017Surgeons need a great sense of touch. They first have to acquire this skill in simulation training before they can perform surgery on actual patients. Having said that, simulators are not just meant to teach the right movements; ideally, they should also provide a true-to-life experience of the surgical field – as is the case in RealSpine surgical training.
01/02/2017Ophthalmology procedures and eye surgeries have been around since ancient times. Today we can hardly imagine the types of circumstances that surrounded any surgical procedures to our perhaps most important sense organ in those days and later eras. Meanwhile, the present and future of this medical specialty looks all the more promising.
01/02/2017Using stents to treat glaucoma is not a new procedure but they have not been implanted into patients on a regular basis until only recently. But this is about to change, which is why MEDICA.de asked what these glaucoma mini-stents are able to do and who may be a good candidate for them. Professor Norbert Pfeiffer answered our questions.
08/09/2016For many patients, the start of hemodialysis marks the lifelong dependency on needing their blood purified. But before they can actually begin treatments, a blood vessel in the patient's arm needs to be enlarged to where it can move enough blood and withstand being connected to the dialysis machine several times per week.
01/09/2016Patients take center stage during surgery. Their treatment should be as gentle and effective as possible, which is why there is a trend towards minimally invasive surgery (MIS). But minimal procedures require better supporting technologies. The hybrid operating room combines surgery and imaging systems and increasingly replaces conventional open surgery approaches with MIS.
01/09/2016Monitoring individual results during surgery with an angiography system? This is already an option in approximately 200 hospitals in Germany. Thanks to intraoperative imaging, major medical procedures can be replaced by minimally invasive surgery because physicians are able to monitor the results immediately. This is gentler on patients and decreases the number of subsequent revision surgeries.
01/09/2016When it comes to the future of medicine, we often ponder how we would like to be treated. On the other hand, there is the issue of how physicians would like to treat their patients. The surgical procedures are determined by the technology that doctors are surrounded by. That’s why technology development also needs to be adapted to the needs of surgeons in the operating room of the future.
01/06/2016Until now, plasma, the fourth state of matter,was consideredfascinatingonly to astrophysicists and science fiction fans. But at this point, it also attracts the interest of medicine because plasma can have many uses in this field. In the future, plasma sterilization could become an important component of hospital hygiene-provided that the right device is being used.
22/01/2016It may fits, but somewhere it still tweaks. Although a suit off the rack serves its purpose, it is still far from being an ideal solution. With a custom made heart it is different. It is similar with implants. Often patients complain about the fact that those implants feel strange. 3D printing is on the best way to change this. Here, the implants are adapted to the carrier.
08/01/2016There are various artificial heart valves available for children, but they have one essential drawback: they need to be replaced because the children are still growing. The artificial valve, on the other hand, remains the same size – and subsequently becomes too small. This is why an artificial heart valve that grows over time would be ideal.
08/12/2015The closure apparatus between the gallbladder and small intestine is frequently injured during gallbladder surgeries. So far, however, there has been no surgical option to bridge tissue defects. Now, a novel implant made of bacterial nanocellulose (BNC) could change this. Its nanofiber network makes it extremely robust so that it is able to take on a supporting function.
09/11/2015Interview with Professor Jürgen Weitz, Director of the Clinic and Polyclinic of Visceral, Thoracic, and Vascular Surgery, University Hospital Carl Gustav Carus at the Technical University Dresden
02/11/2015Performing surgery in a hybrid operating room is meant to be a relief for the staff and offer patients new options for treatment. What is actually so different about this hybrid operating room, what can you expect and what should you keep in mind during the planning process?
02/11/2015Minimally invasive surgeries are gentler on the patient but have one distinct disadvantage for the surgeon: he is not able to interact directly with the operating field. Sometimes he misses impressions that are very important to the success of the intervention. The MiroSurge robot for surgical applications which transmits feedback to the surgeon can help.
01/07/2015In the case of cardiac arrhythmia, the normal heart rate gets out of balance due to various reasons. In some cases, it is necessary to implant a cardiac pacemaker. Just like with any intervention, this type of surgery also involves risks. In the worst-case scenario, this can lead to abnormal wound healing or obliteration of the vascular system.
08/10/2014The NanoKnife® therapy practiced at the Prostate Center in Offenbach am Main removes prostate tumors in a gentle manner im comparison to prostatectomy or radiation therapy. In this interview with MEDICA.de, Professor Michael K. Stehling explains the advantages of the focal therapy.
01/10/2014Herniated discs can have very different effects: some cause no discomfort and are only discovered by accident; others can cause paralysis or cause patients to be in great pain. For the most part, these problems develop suddenly after an awkward movement – at least that is what patients report.
08/09/2014You find out after surgery that the left knee was treated instead of the right one. Although such mistakes rarely happen, they can have serious consequences – both for the patient and the image of the physician and the hospital.
01/09/2014When very young children already need to be in the operating room, it’s not just the parents that are concerned. This type of situation is a special challenge for the entire operating team, because children are always very special patients - especially since they are not just simply small grown-ups!
08/08/2014A magnesium implant will soon be available to help patients, who exhibit damage in the high-pressure area of the heart. The implant protects a tissue matrix where new cells that replace the affected tissue are meant to grow. The implant itself is supposed to completely dissolve after several months. MEDICA.de spoke with D. Eng. Thomas Hassel about this exciting project.
08/07/2014Gentle, safe, precise, fast – surgical interventions need to meet many demands: laws and regulations concerning safety, the desire for the best possible health outcome, economic requirements of hospitals and ever-changing technology make up today’s framework for surgery. As a consequence, operating theaters and the way they are equipped change, too.
01/07/2014Large burns require skin grafting. Surgeons remove split-thickness skin grafts and apply them to the injured areas. Now skin that has been made in a laboratory is meant to help in covering burns as well as chronic wounds and thus promote the healing process. Researchers in Zurich have been working on this for more than 13 years.
01/07/2014The not so popular “love handles“ could revolutionize medicine in the near future. In cooperation with the University of Rostock (Professor Hermann Seitz), the human med AG Company currently seeks to develop a device that is able to gently remove adipose tissue during surgery and subsequently isolate stem cells.
03/02/2014Differentiating tumor tissue from healthy tissue isn’t always easy for surgeons. Scattered cancer cells and early cancer are often hard to detect with the naked eye. A special camera now makes even the tiniest remainder of a tumor visible during surgery.
06/01/2014Even medical risk products are not always tested as thoroughly as would be necessary – be it because of criminal energy, lack of know-how or financial reasons. A revision of clinical trial procedures could not only fix loop holes and methodological flaws. Products and methods could also be brought into general medical care more quickly under new rules.
06/01/2014In the operating room, it is especially important for the used devices to be safe and tolerable to the human body. Switzerland also shares this point of view. MEDICA.de spoke with Dr. Christoph Röder from the University of Bern about approval procedures and regulations that are being pursued in Swiss operating rooms.
06/01/2014Whether a surgical suture is better applied manually or with a surgical stapler can be determined through trial and error. Determining which method guarantees patient safety best should also not just be based on a surgeon’s experience. Controlled studies are the method of choice to assess both well-proven and new techniques in the operating room.
05/01/2014Eventually, all adults need to see a physician for colon cancer prevention. While the exam goes by quickly thanks to sedation, it sometimes leads to a follow-up procedure if a growth in the colon could not be removed with the endoscope and requires open surgery.
