Ukuhlinzwa kokufakwa kwe-stent endoscopic

Ukufakwa kwe-endoscopic stent kuyindlela esebenzisa i-endoscopy ukuze ibeke i-stent emzileni wokugaya ovimbekile noma owumngcingo ukuze kwakhiwe kabusha umsebenzi wayo ongavimbekile. Ifanele ukuvinjelwa komdlavuza womminzo, i-stenosis yomdlavuza womminzo, ukuvinjwa okuyingozi kwe-pylorus ne-duodenum, ukuvinjelwa komdlavuza we-colorectal, i-benign biliary pancreatic duct stenosis, i-bile pancreatic drainage, i-anastomotic fistula, njll. Ezigulini ezinomdlavuza ovimbekile noma i-stenosis, lokhu kuhlinzwa kuthathwa njenge-palliative ukuhlinzwa Indlela yokuhlinza 1. Izindlela zokubulala izinzwa kanye nezindlela zokuphepha Izindlela zokubulala izinzwa zihlukaniswa zibe izinzwa zendawo kanye nezinzwa ezivamile I-anesthesia yendawo: i-2% ~ 4% i-lidocaine isetshenziselwa izinzwa ze-pharyngeal, i-spray noma ukuphathwa ngomlomo. ② Izinzwa ezivamile: Kubantu abanokucindezeleka kwengqondo noma izingane ezingakwazi ukubambisana, izinzwa ezivamile kufanele zisetshenziswe kaningi. Umthamo wezidakamizwa ezibulala izinzwa uyahlukahluka kumuntu nomuntu. 2. Izindlela zokuhlinza (1) Isiguli kufanele sibekwe endaweni ethambekele noma sincike kancane kwesokunxele, futhi ezimweni ezikhethekile, singabekwa endaweni yesobunxele noma yokulala. (2) Ukuhlolwa kwe-endoscopic okujwayelekile kukhomba indawo yesilonda. Ngaphansi kwe-X-ray fluoroscopy, intambo yomhlahlandlela ifakwa ngama- endoscopic forceps bese kufakwa ishubhu lokuqhathanisa. I-ejenti yokuqhathanisa encibilikayo emanzini njenge-meglumine diatrizoate iyajovwa ukuze ibuke isimo sesilonda. (3) Khetha isitenti esifanelekile bese usiphushela endaweni ethintekile (njengendawo encane noma evalekile) ngocingo oluqondisayo ngaphansi kwe-X-ray fluoroscopy. Okunye, faka i-stent ku-endoscope eduze nesistimu yokuphusha i-stent ukuze ukhulule i-stent ngaphansi kokubuka okuqondile kwe-endoscopic. (4) Ngaphansi kwe-X-ray fluoroscopy kanye nokubuka okuqondile kwe-endoscopic, lungisa ngesikhathi esifanele indawo yokukhishwa kwe-stent futhi ukhulule i-stent, futhi ukhiphe okokufakelwa. (5) Ezigulini ezihlinzwa nge-bile duct noma i-pancreas duct, ngemva kokukhipha i-stent, kufanele zizame ukuheha i-bile noma ijusi ye-pancreatic kanye ne-agent ehlukile ngangokunokwenzeka, futhi ziqinisekise ukuthi ukugeleza kwamanzi akuvimbekile ngaphambi kokuhoxisa i-endoscope. (6) Ifilimu ye-X-ray yokuqinisekisa ukuma kobakaki
