Utyando lokubeka i-stent kwi-Endoscopic

Ukufakwa kwe-stent ye-Endoscopic bubuchule obusebenzisa i-endoscopy ukubeka i-stent kwindawo ethintelweyo okanye ecuthekileyo yokugaya ukuze iphinde iphinde iphinde isebenze. Ifanelekile ukuvaleka komhlaza wommizo, i-stenosis yomhlaza wommizo, isithintelo esibi se-pylorus kunye ne-duodenum, ukuphazamiseka komhlaza we-colorectal, i-benign biliary pancreatic duct stenosis, i-biliary pancreatic drainage, i-anastomotic fistula, njl. utyando Indlela yokuhlinzwa 1. Iindlela ze-Anesthesia kunye nezilumkiso Iindlela ze-anesthesia zihlukaniswe kwi-anesthesia yendawo kunye ne-anesthesia jikelele I-anesthesia yendawo: i-2% ~ 4% i-lidocaine isetyenziselwa i-anesthesia ye-pharyngeal, i-spray okanye i-oral administration. ② I-anesthesia jikelele: Kubantu abanoxinzelelo lwengqondo okanye abantwana abangakwazi ukusebenzisana, i-anesthesia jikelele kufuneka isetyenziswe rhoqo. Umthamo wamachiza okuthomalalisa uyohluka kumntu nomntu. 2. Iindlela zokwenza utyando (1) Isigulane kufuneka sibekwe kwindawo ethe tye okanye ngokuyinxenye ekhohlo ukungqiyama, kwaye kwiimeko ezikhethekileyo, zinokuthi zibekwe kwindawo ekhohlo okanye ekhohlo. (2) Uvavanyo lwe-endoscopic oluqhelekileyo lubonisa indawo yesilonda. Ngaphantsi kwe-X-ray fluoroscopy, ucingo lwesikhokelo lufakwe kwi-endoscopic forceps kunye ne-tube yokuchasana ifakwe. I-agent echaseneyo enyibilikayo yamanzi efana ne-meglumine diatrizoate iyatofwa ukujonga imeko yesilonda. (3) Khetha isitanti esifanelekileyo kwaye usityhale kwindawo echaphazelekayo (njengendawo emxinwa okanye evalekileyo) ngocingo lwesikhokelo phantsi kweX-reyi fluoroscopy. Kungenjalo, faka i-stent kwi-endoscope ecaleni kwendlela yokutyhala i-stent ukukhulula i-stent phantsi kombono othe ngqo we-endoscopic. (4) Ngaphantsi kwe-X-ray fluoroscopy kunye ne-endoscopic ukujonga ngokuthe ngqo, ukulungisa ngexesha elifanelekileyo indawo yokukhutshwa kwe-stent kwaye ukhulule i-stent, kwaye ususe ukufakwa. (5) Kwizigulane ezithatha i-bile duct okanye i-pancreatic duct utyando, emva kokukhulula i-stent, kufuneka bazame ukutsala i-bile okanye i-pancreatic juice kunye ne-agent echaseneyo kangangoko kunokwenzeka, kwaye baqinisekise ukuba ukukhutshwa kwamanzi akuthinteki ngaphambi kokuba kuhoxiswe i-endoscope. (6) Ifilimu ye-X-ray ukuqinisekisa indawo yesibindi
