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 ubundi insinga iyobora irashobora kunyuzwa mugihe sphincterotome ishyizwe.
2. Uburebure bw'icyuma
Uburebure bwicyuma bugomba kwitabwaho, muri rusange mm 20-30.Uburebure bwinsinga ziyobora bugena impande ya arc yicyuma cya arc nuburebure bwimbaraga mugihe cyo gutemwa.Kubwibyo, umwanya muremure wicyuma, niko wegera "inguni" ya arc ni ku cyerekezo cya anatomical cyerekezo ya pancreaticobiliary duct intubation, bishobora kuba byoroshye intubate neza.Muri icyo gihe, insinga ndende cyane zishobora gutera amakosa ya sphincter hamwe ninzego ziyikikije, bikaviramo ingorane zikomeye nko gutobora, bityo hakabaho "icyuma cyubwenge" cyujuje ibyifuzo byumutekano mugihe cyujuje uburebure.
3. Kumenyekanisha Sphincterotome
Kumenyekanisha sphincterotome nigice cyingenzi cyane, kugirango byorohereze umukoresha gusobanukirwa byoroshye no kumenya aho sphincterotome ihagaze mugihe cyibikorwa byoroheje kandi byingenzi, no kwerekana aho bihurira hamwe numwanya uhagaze neza.Muri rusange, imyanya myinshi nka "tangira", "gutangira", "hagati" na "1/4" ya sphincterotome izashyirwaho ikimenyetso, muri byo 1/4 cyambere hamwe nicyuma cyo hagati cyicyuma cyubwenge nikibanza gifite umutekano 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, hamwe nuburebure bwicyuma cyerekanwe munsi yicyerekezo, birashoboka kumenya niba icyuma gishobora gukora neza sphincter.Nyamara, buri sosiyete ifite ibirango bitandukanye mubikorwa byo gukora ibirango, bigomba kumvikana.
