Ibikoresho bya ERCP Inshuro eshatu Lumen imwe Koresha Sphincterotome yo Gukoresha Endoskopi

1. Diameter
Diameter ya sphincterotome muri rusange ni 6Fr, naho igice cyo hejuru kigenda kigabanuka kugeza kuri 4-4.5Fr.Diameter ya sphincterotome ntikeneye kwitabwaho cyane, ariko irashobora kumvikana muguhuza diameter ya sphincterotome nimbaraga zikora za endoscope.Ese indi nsinga iyobora irashobora kunyuzwa mugihe sphincterotome ishyizwe.
2. Uburebure bw'icyuma
Uburebure bw'icyuma bugomba kwitabwaho, muri rusange mm 20-30.Uburebure bwinsinga ziyobora bugena impande ya arc yicyuma cya arc nuburebure bwimbaraga mugihe cyo gutemwa.Kubwibyo, igihe kirekire insinga z'icyuma, niko wegera "inguni" ya arc ni ku cyerekezo cya anatomique cyerekezo ya pancreaticobiliary duct intubation, bishobora kuba byoroshye kwinjiza neza.Muri icyo gihe, insinga ndende cyane zishobora gutera nabi sphincter ninzego ziyikikije, bikaviramo ingorane zikomeye nko gutobora, bityo hakaba "icyuma cyubwenge" cyujuje ibyifuzo byumutekano mugihe cyujuje uburebure.
3. Kumenyekanisha Sphincterotome
Kumenyekanisha sphincterotome nigice cyingenzi cyane, cyane cyane kugirango byorohereze uyikoresha gusobanukirwa byoroshye no kumenya aho sphincterotome ihagaze mugihe cyibikorwa byihishe kandi byingenzi, no kwerekana umwanya uhuriweho hamwe numwanya uhagaze neza.Muri rusange, imyanya myinshi nka "gutangira", "gutangira", "hagati" na "1/4" ya sphincterotome izashyirwaho ikimenyetso, muri byo 1/4 cyambere hamwe nicyuma cyo hagati cyicyuma cyubwenge ni imyanya itekanye kuri gukata, bikunze gukoreshwa.Mubyongeyeho, ikimenyetso cyo hagati ya sphincterotome ni radiopaque.Mugukurikirana X-ray, imyanya igereranije ya sphincterotome muri sphincter irashobora kumvikana neza.Muri ubu buryo, ufatanije nuburebure bwicyuma cyerekanwe munsi yerekwa bitaziguye, birashoboka kumenya niba icyuma gishobora gukora neza sphincter.Nyamara, buri sosiyete ifite ingeso zitandukanye mubirango mugukora ibirango, bigomba kumvikana.
