Ultrasonic sectoral scanning was used to determine the type of biliary tract dyskinesias in the course of digestion. 89 patients with different gastroenterological diseases were examined. 21 healthy subjects made up the control group. The process of gallbladder contraction was conventionally divided into 3 phases. In practically healthy subjects, the first phase was marked by gallbladder contraction from the neck down to the bottom while the gallbladder assumed an optimally suitable form for prolonged contraction. The second phase involved rapid contraction (during 15 min the gallbladder size reduced by 28.8%). The third phase involved slow contraction (during 30 min the gallbladder decreased in size by another 29%). 5 types of dyskinetic disorders were distinguished. This permitted diagnosing the focus of pathology within the system of the biliary tract together with administering the differentiated treatment. 相似文献

The number of bone marrow transplantations performed to treat diseases such as leukemia, lymphoma, and aplastic anemia has been increasing during the past 2 decades. Improvements in histocompatibility testing, transfusion support, conditioning regimens, and antibiotics have dramatically improved survival after transplantation. As more patients survive the acute phase of bone marrow transplantation and leave major medical centers for their homes, healthcare providers across the country are caring for these patients and their transplantation-associated complications. Graft-versus-host disease (GVHD) of the skin, liver, and gastrointestinal tract are complications that patients may experience months after transplantation. As clinicians, advanced practice nurses encounter these patients in clinics, hospitals, and intensive care units, whether it be for specific GVHD-associated problems or other health conditions. This article reviews the current standards of care for the prevention, diagnosis, and treatment of GVHD of the gastrointestinal tract. 相似文献

Hepatocyte transplantation represents a supplementary strategy for treating liver diseases. Several methods including extracorporeal devices, cell transplantation and implanted tissue-engineered units were proposed as liver support before liver transplantation. The ability to repopulate the liver with healthy and disease-resistant hepatocytes opens up new possibilities for correcting genetic disorders and treating patients with chronic liver diseases. Some results of experimental and clinical therapy of liver diseases are summarized in this review. 相似文献

Obesity is considered an emerging epidemic that is often associated with non-alcoholic fatty liver disease. Among the therapeutic options for morbid obesity, bariatric surgery plays an important role when conventional therapies fail. The effects of bariatric surgery on liver function and morphology are controversial in the literature. Liver failure has been reported after jejunoileal bypass (JIB), biliopancreatic diversion and gastric bypass. Biliointestinal bypass (BIB) is considered an effective procedure among recently introduced bariatric surgery techniques. It is a clinically safe, purely malabsorptive operation in which the blind intestinal loop of the JIB is anastomosed to the gallbladder, allowing a portion of bile to transit into excluded intestinal tract. BIB is the only procedure, to our knowledge, to have no liver side effects reported in the literature. We report the case of a young obese woman who developed liver failure 8 mo after BIB. She had a rapid weight loss (70 kg) with a reduction in body mass index of 41% from January to September 2012. Because of a severe hepatic decompensation, she was referred to a transplantation centre. We strongly believe that the most important pathogenetic mechanism involved in the development of liver injury is the rapid weight loss that produced a significant fatty liver infiltration. 相似文献

目的通过半定量RT-PCR的方法研究多药耐药相关蛋白-3、4(MRP3、MRP4)基因在患胆固醇结石病人的胆囊中与非结石人群胆囊中表达的异同。方法用半定量RT-PCR的方法研究MRP3、MRP4在胆固醇结石病人与无结石人群胆囊上皮组织中的表达的异同。结果在患胆固醇结石的胆囊组织中,MRP3和MRP4同时表达,而且表达水平均显著高于正常胆囊;另外,MRP3的表达水平显著高于MRP4(P<0.001)。在正常(对照组)胆囊组织中,仅有MRP3表达,而未能检测到MRP4。结论胆固醇结石病人的胆囊组织中MRP3、MRP4蛋白的表达高于无胆固醇结石人群,提示它们可能促进人胆囊胆固醇结石形成。 相似文献

The biological importance of the aquaporin family of water channels was recently acknowledged by the 2003 Nobel Prize for Chemistry awarded to the discovering scientist Peter Agre. Among the pleiotropic roles exerted by aquaporins in nature in both health and disease, the review addresses the latest acquisitions about the expression and regulation, as well as physiology and pathophysiology of aquaporins in the hepatobiliary tract. Of note, at least seven out of the thirteen mammalian aquaporins are expressed in the liver, bile ducts and gallbladder. Aquaporins are essential for bile water secretion and reabsorption, as well as for plasma glycerol uptake by the hepatocyte and its conversion to glucose during starvation. Novel data are emerging regarding the physio-pathological involvement of aquaporins in multiple diseases such as cholestases, liver cirrhosis, obesity and insulin resistance, fatty liver, gallstone formation and even microparasite invasion of intrahepatic bile ducts. This body of knowledge represents the mainstay of present and future research in a rapidly expanding field. 相似文献

Background: To assess the accuracy of computed tomographic (CT) imaging in the detection of spread and staging of gallbladder carcinoma.
Methods: CT findings of spread of gallbladder carcinoma in 59 Japanese patients who underwent radical surgery were correlated retrospectively
with pathologic findings.
Results: The incidence of histologically proven nodal involvement was 54% (32 patients) and the most common spread of gallbladder
carcinoma. The sensitivities in CT detection of N1 and N2 nodal involvement were 36% and 47%, respectively; positive predictive
values were 94% and 92%, respectively. Direct extension to the liver, extrahepatic bile duct, and gastrointestinal tract or
pancreas were histologically confirmed in 24, 18, and five patients. The sensitivities in the CT detection of direct spread
to the liver of less than 2 cm, more than 2 cm, the extrahepatic bile duct, and the gastrointestinal tract or pancreas were
65%, 100%, 50%, and 57%, respectively; positive predictive values were 77%, 100%, 90%, and 100%, respectively. The incidence
of liver metastases and involvement of interaortocaval nodes were 7% and 16%, respectively. The sensitivities in CT detection
of liver metastases and involvement of interaortocaval nodes were 75% and 21%, respectively; positive predictive values were
100% and 86%, respectively. CT could not detect direct spread to omentum and peritoneal seedings.
Conclusion: For detecting the spread of gallbladder carcinoma, CT imaging has low to moderate sensitivity; however, CT imaging can help
in determining resectability and in planning the treatment, especially in advanced-stage gallbladder carcinoma, because of
a high positive predictive value.
