Endoscopic stent kuiswa kuvhiyiwa

Endoscopic stent placement inyanzvi inoshandisa endoscopy yekuisa stent mune yakavharika kana yakatetepa yekugadzika turakiti kuti igadzirise basa rayo risina kuvharika. Inokodzera kuvharwa kwegomarara reguroguro, kenza yegurokuro stenosis, kuvharika kwakashata kwepylorus uye duodenum, colorectal cancer obstruction, benign biliary pancreatic duct stenosis, biliary pancreatic drainage, anastomotic fistula, nezvimwewo. Kuvhiyiwa Nzira yekuvhiya 1. Nzira dzeAnesthesia uye zvidziviriro Nzira dzeanesthesia dzakakamurwa kuva anesthesia yemunharaunda uye general anesthesia Local anesthesia: 2% ~ 4% lidocaine inoshandiswa pa pharyngeal anesthesia, spray kana oral administration. ② General anesthesia: Kune vanhu vane kushushikana mupfungwa kana vana vasingakwanisi kushandira pamwe, general anesthesia inofanira kushandiswa kakawanda. Chiyero chemishonga yeanesthetic chinosiyana pamunhu nemunhu. 2. Nzira dzokuvhiya dzokuvhiya (1) Murwere anofanirwa kuiswa panzvimbo yakareruka kana kuti chikamu chekuruboshwe chakatsamira, uye mumamiriro ezvinhu anokosha, anogona kuiswa panzvimbo yekuruboshwe kana kuti supine. (2) Routine endoscopic kuongorora inoratidza nzvimbo yeronda. Pasi pe X-ray fluoroscopy, tambo yekutungamira inopinzwa kuburikidza ne endoscopic forceps uye inosiyanisa chubhu inoiswa. Mvura inonyungudika yekusiyanisa senge meglumine diatrizoate inobaiwa kuti ione mamiriro eronda. (3) Sarudza stent yakakodzera uye uisundire kunzvimbo yakakanganisika (senzvimbo yakamanikana kana yakavharika) kuburikidza newaya inotungamira pasi peX-ray fluoroscopy. Neimwe nzira, isa stent muendoscope pamwe neiyo stent kusunda system kuti isunungure stent pasi pekutarisa endoscopic yakananga. (4) Pasi peX-ray fluoroscopy uye endoscopic yakananga maonero, panguva yakakodzera gadzirisa nzvimbo yekusunungurwa kwe stent uye kusunungura stent, uye kubvisa kuisirwa. (5) Kune varwere vari kuvhiyiwa bile duct kana pancreatic duct kuvhiyiwa, mushure mekuburitsa stent, vanofanirwa kuedza kukwezva bile kana pancreatic muto uye musiyano mumiririri zvakanyanya sezvinobvira, uye kusimbisa kuti iyo yemvura haina kuvharwa isati yadzoreredza endoscope. (6) X-ray firimu kusimbisa nzvimbo yebraki
