Serum adiponectin and progranulin levels are associated with gallstone disease

Sandvoß, Ruth 06 February 2018 (has links)
Das Fettgewebe sezerniert hormonähnliche Proteine, sogenannte Adipozytokine oder Adipokine. Es sind zahlreiche Zusammenhänge zwischen Adipokinen und dem Auftreten von Adipositas und adipositasassoziierten Erkrankungen beschrieben. Gallensteine sind mit Adipositas assoziiert und stellen aufgrund der Häufigkeit des Auftretens und der damit verbundenen Kosten ein großes gesundheitsökonomisches Problem dar. Ziel dieser Arbeit war es zu prüfen, ob eine Assoziation der Cholelithiasis mit den Serumspiegeln von Adiponectin, Chemerin, Vaspin, Progranulin, FGF21 und AFABP vorliegt. Dazu wurde eine Kohorte von 1022 Sorben, einer nationalen Minderheit aus der Oberlausitz, statistisch ausgewertet. Für Chemerin, Vaspin, FGF21 und AFABP konnte kein Zusammenhang ermittelt werden. Bei den männlichen Gallensteinträgern war im Vergleich zu der Kontrollgruppe der Serumporgranulinspiegel signifikant erhöht, wobei unklar bleibt, wie die Serumkonzentration mit der Konzentration in der Gallenblase korreliert und wie die geschlechtsspezifischen Unterschiede zustande kommen. Für Adiponectin bestätigten sich bereits vorliegende Aussagen, dass dieses Adipokin einen protektiven Effekt auf die Gallensteinentstehung hat. Es sind weitere longitudinale und funktionelle Studien notwendig, um die Pathomechanismen weiter zu klären.

Dispositivo de extração de cálculos intracoledocianos por inclusão em polímero auto expansível / Device for extraction of choledochal calculi by inclusion in auto expandable polymer

Nascimento Neto, Saturnino Ribeiro do 07 April 2017 (has links)
A cirurgia geral tem experimentado após a década de noventa, com o desenvolvimento da laparoscopia, espetacular melhoria em todos os resultados. Uma menor morbimortalidade se deve ao menor trauma cirúrgico causado pelas cirurgias feitas por pequenos orifícios. O desenvolvimento tecnológico de endoscópios rígidos e flexíveis, propiciou aos médicos um acesso direto às patologias abdominais sem a necessidade de grandes aberturas da cavidade celômica. Assim, houve grande melhoria não somente dos resultados estéticos, mas principalmente na redução de morbidade. Nas cirurgias das vias biliares isso não foi diferente. Com o aprimoramento da técnica cirúrgica laparoscópica, a via de acesso cirúrgico endoscópica passou a ser preferida. Entretanto, a realidade da laparoscopia em muitos locais não se faz presente no tratamento da coledocolitíase, principalmente quando tal patologia é tratada em centros com menor aporte de recursos financeiros. A retirada de cálculos da via biliar principal exige o uso de fibroscópios de alto custo, bem como dispositivos descartáveis de alto valor, forçando o cirurgião desprovido de tais recursos muitas vezes a realizar a cirurgia de maneira convencional ou, no mínimo, aumentado a dificuldade do procedimento por via laparoscópica. Com o intuito de equacionar tal dificuldade, propõe-se com este dispositivo, mais um conceito de abordagem para este problema, inédito, testado em macroambiente, com utilização de cateter contendo balão com polímero autoexpansivo capaz de apreender os cálculos da via biliar principal por meio de inclusão. Utilizando os preceitos da colangiografia per operatória, o novo método propõe a retirada dos cálculos da via biliar principal de maneira indireta com auxílio de métodos de imagem comuns à maioria dos hospitais de média complexidade. / General surgery has experienced after the nineties, with the development of laparoscopy, spectacular improvement in outcomes. Lower morbidity and mortality is due to less surgical trauma caused by surgeries performed by small orifices. The technological development of rigid and flexible endoscopes gave doctors direct access to abdominal pathologies without the need for large openings in the coelomic cavity. Thus, there was a great improvement not only in the aesthetic results, but mainly in the reduction of morbidity. In biliary surgeries this was not different. With the improvement of the laparoscopic surgical technique, the endoscopic cirurgical approach was favored. However, the reality of laparoscopy in many places is not present in the treatment of choledocholithiasis, especially when such pathology is treated in centers with lower financial resources. Removal of stones from the main biliary tract requires the use of high-cost fibroscopes as well as high-value disposable devices, forcing the surgeon devoid of such resources, many times undergoing conventional surgery or at a minimum, increasing the difficulty of the procedure by laparoscopic approach. With the purpose of equating this difficulty, it is proposed with this device, another concept of approach to this problem, novel, tested in macro environment, with the use of balloon catheter containing self expanding polymer capable of grasping the calculi of the common bile duct by inclusion. Using the trans-operative cholangiography precepts, the new method proposes to extract the principal biliary tract calculi indirectly with the help of imaging methods common to the most hospitals.
