A very aggressive disease with a poor prognosis, gallbladder cancer may be connected to higher exposure to estrogens, according to a group of researchers at the University of Houston (UH). http://phys.org/news201177449.html Medicine & Health Mon, 16 Aug 2010 12:00:01 EST news201177449 As part of the only U.S. prospective multicenter clinical trial to compare natural orifice translumenal endoscopic surgery (NOTES) to laparoscopy, surgeons at the University of California, San Diego School of Medicine have performed the trial's first oral gallbladder removal. This landmark study will evaluate whether or not NOTES is safe and as effective as traditional laparoscopic surgery. http://phys.org/news197735156.html Medicine & Health Wed, 07 Jul 2010 15:50:02 EST news197735156 The incidence of gallstones is higher in patients after radical gastrectomy than in the general population. The current literature suggests that this higher incidence is related to gallbladder motility disorder after surgery. A research group in China investigated the association between the XbaI polymorphisms of APOB gene and gallstone formation after gastrectomy. Patient with the X+ allele of APOB gene was found to be another important risk factor of gallstone formation after radical gastrectomy. http://phys.org/news194693834.html Medicine & Health Wed, 02 Jun 2010 10:37:32 EST news194693834 A new study suggests that the bacteria that cause typhoid fever collect in tiny but persistent communities on gallstones, making the infection particularly hard to fight in so-called "carriers" - people who have the disease but show no symptoms. http://phys.org/news186072281.html Medicine & Health Mon, 22 Feb 2010 15:00:13 EST news186072281 (AP) -- Gallbladder surgery is usually a very safe operation, but a powerful congressman's death is a reminder of the known risks. http://phys.org/news185000137.html Medicine & Health Wed, 10 Feb 2010 05:30:01 EST news185000137 Fibrin sealant has been an extremely effective and widely used adjunct to surgical procedures to control diffuse slow bleeding over large surfaces. In addition, fibrin sealant has been used as a carrier for other compounds. Thus, it has been used to release medicines slowly at a fixed site and is therefore effective for a long time. http://phys.org/news180709030.html Medicine & Health Tue, 22 Dec 2009 15:00:05 EST news180709030 Physicians should "throttle back" from routinely ordering stress tests and prescribing beta blockers to patients before non-cardiac surgeries, according to a report by the University of Michigan released online this week. http://phys.org/news179002118.html Medicine & Health Wed, 02 Dec 2009 19:20:11 EST news179002118 A research team from Germany analyzed the pathogenetic role and potential clinical usefulness of the epidermal growth factor receptor (EGFR) and the human epidermal growth factor receptor 2 (HER2) in patients with advanced biliary tract cancer (BTC). They found that routine testing and therapeutic targeting of HER2 does not seem to be useful in patients with BTC, while targeting EGFR may be promising. http://phys.org/news174916004.html Medicine & Health Fri, 16 Oct 2009 18:50:01 EST news174916004 Acute hepatocellular injury is a commonly encountered phenomenon in patients with cholelithiasis and concomitant common bile duct (CBD) stones. However, in clinical practice, it seemed to occur also in cholelithiasis patients without evidence of CBD stones. Its incidence and final outcome necessitated clarification. http://phys.org/news170423663.html Medicine & Health Tue, 25 Aug 2009 15:00:01 EST news170423663 Primary sclerosing cholangitis (PSC) is an idiopathic chronic cholestatic inflammatory liver disease characterized by diffuse fibrosing inflammation of intra- and/or extrahepatic bile ducts, resulting in bile duct obliteration, biliary cirrhosis, and eventually hepatic failure. One of the most common symptoms at the time of presentation of PSC is mild to severe abdominal pain localized in the right upper quadrant. However, the mechanisms responsible for the abdominal pain in PSC are not fully understood. http://phys.org/news169120394.html Medicine & Health Mon, 10 Aug 2009 10:53:42 EST news169120394 Based on serum bank material, BA profiling was applied in IBD patients and healthy controls which showed that most but not all BA species were decreased to a different extent in CD and UC. BA decreases were highly pronounced in CD patients with surgical interventions in the gut. http://phys.org/news166970717.html Medicine & Health Thu, 16 Jul 2009 17:50:01 EST news166970717 Overall prognosis for gallbladder cancer appears to be improving, although many patients still have incurable disease and poor survival rates, according to a report in the May issue of Archives of Surgery. http://phys.org/news161882928.html Medicine & Health Mon, 18 May 2009 16:29:11 EST news161882928 Obesity and gallstones often go hand in hand. But not in mice developed at Washington University School of Medicine in St. Louis. Even when these mice eat high-fat diets, they don't get fat, but they do develop gallstones. Researchers say the findings offer clues about genetic factors related to gallstones, and they believe better understanding of those factors may one day allow physicians to monitor people at risk and even, perhaps, to intervene before gallstones become a serious problem. http://phys.org/news160910670.html Medicine & Health Thu, 07 May 2009 10:25:00 EST news160910670 Physicians at Northwestern Memorial Hospital successfully removed a patient's gallbladder through the vagina, making them the first in the Midwest and the third in the country to perform the innovative procedure. The technique, known as NOTES—natural orifice translumenal endoscopic surgery—is gaining in popularity and has been characterized by many in the medical profession as laying the groundwork for truly "incisionless" surgery. http://phys.org/news154786732.html Medicine & Health Wed, 25 Feb 2009 12:19:32 EST news154786732 In April of last year, surgeons at NewYork-Presbyterian Hospital/Columbia University Medical Center made headlines by removing a women's gallbladder through her uterus using a flexible endoscope, aided by several external incisions for added visibility. Now, they have performed the same procedure without a single external incision in what surgeons report may be the first surgery of its kind in the United States. http://phys.org/news136466103.html Medicine & Health Mon, 28 Jul 2008 12:15:03 EST news136466103
