Opaleshoni ya Endoscopic stent

Endoscopic stent placement ndi njira yomwe imagwiritsa ntchito endoscopic kuyika stent m'matumbo otsekeka kapena ocheperako kuti apangenso ntchito yake yosatsekeka. Oyenera kummero kutsekereza khansa, kummero khansa stenosis, zilonda kutsekereza pylorus ndi duodenum, colorectal khansa kutsekeka, chosaopsa biliary pancreatic duct stenosis, biliary pancreatic ngalande, anastomotic fistula, etc. Opaleshoni Njira yopangira opaleshoni 1. Njira za anesthesia ndi njira zodzitetezera Njira za anesthesia zimagawidwa mu anesthesia wamba ndi anesthesia wamba: 2% ~ 4% lidocaine wa lidocaine amagwiritsidwa ntchito pa pharyngeal anesthesia, spray kapena pakamwa. ② Chiwopsezo chambiri: Kwa anthu omwe ali ndi kupsinjika maganizo kapena ana omwe sangathe kugwirizana nawo, anesthesia wamba ayenera kugwiritsidwa ntchito nthawi zambiri. Mlingo wa mankhwala opha ululu umasiyanasiyana munthu ndi munthu. 2. Njira zopangira opaleshoni (1) Wodwalayo ayenera kuikidwa pamalo otsetsereka kapena kumanzere pang'ono akutsamira, ndipo muzochitika zapadera, akhoza kuikidwa kumanzere kapena kumtunda. (2) Kufufuza kwanthawi zonse kwa endoscopic kumawonetsa malo omwe ali ndi zilondazo. Pansi pa X-ray fluoroscopy, waya wowongolera amalowetsedwa kudzera mu endoscopic forceps ndipo chubu chosiyanitsa chimayikidwa. Mankhwala osungunuka m'madzi monga meglumine diatrizoate amabayidwa kuti awone momwe zilondazo zilili. (3) Sankhani stent yoyenera ndikukankhira kudera lomwe lakhudzidwa (monga malo opapatiza kapena otsekeka) kudzera pa waya wowongolera pansi pa X-ray fluoroscopy. Kapenanso, ikani stent mu endoscope motsatira dongosolo lokankhira stent kuti mutulutse stent poyang'ana endoscopic mwachindunji. (4) Pansi pa X-ray fluoroscopy ndi mawonedwe achindunji a endoscopic, konzani nthawi yake malo otulutsa stent ndikutulutsa stent, ndikuchotsa choyikacho. (5) Kwa odwala omwe akuchitidwa opaleshoni ya ndulu kapena pancreatic duct, atatulutsa stent, ayenera kuyesa kukopa ndulu kapena madzi a pancreatic ndi mankhwala osiyanitsa momwe angathere, ndikutsimikizira kuti ngalandeyo ilibe chotchinga musanachotse endoscope. (6) Kanema wa X-ray kuti atsimikizire malo a brack
