Ziziphi iintlobo ze-stents ze-digestive tract

Izibilini zesisu ikakhulu ziquka i-esophageal stents, i-biliary stents, i-pancreatic stents, kunye ne-intestinal stents. Esophageal stents zisetyenziswa ikakhulu kwi stenosis yommizo obangelwa ngumhlaza wommizo, biliary stents zisetyenziswa ikakhulu kwi biliary obstruction ebangelwa yi cholangiocarcinoma, pancreatic stents zisetyenziswa ikakhulu ukubola kwe pancreatic ngexesha eli acute pancreatitis, kwaye intestinal stents zisetyenziswa ikakhulu kwi intestinal stenosis ebangelwa ngumhlaza wekholoni. . Izitenti zoMqalazo zinokwahlulwa zibe zizitenti ezingenanto, izinti ezigqunyiweyo, kunye nezinti ezigqunywe ngokupheleleyo. Ukuba i-stents engenanto ibekwe kummizo, ayinakususwa ngenxa yokuba izicubu zomhlaza ezingqongileyo ziya kukhula ecaleni kommizo.

Isiqingatha se-stents esigqunywe ngokusisiseko silungisiwe, ngelixa i-stents egqunywe ngokupheleleyo inokuthintela ukukhula kwezicubu zethumba ngokuzigquma ngomaleko wefilimu yeplastiki kwaye inokuphinda isetyenziswe. I-Biliary stent ikakhulu ibandakanya i-stent yesinyithi kunye ne-stent yeplastiki, enokufakwa kumbhobho wenyongo ukunciphisa iimpawu ze-jaundice ezibangelwa ngumhlaza wenyongo. I-pancreatic stent ifakwe ngaphakathi kwi-pancreatic duct emva kotyando lokususa ilitye le-ERCP ukukhusela uxinzelelo olugqithisileyo ngaphakathi kombhobho kunye nokwandisa i-pancreatitis. Amathumbu e-intestinal angafakwa ngexesha lokuvalelwa kwamathumbu ukuze kuthotywe iimpawu zokuphazamiseka kwe-fecal.
