Ibikoresho bya ERCP Ikoreshwa rimwe rya Sphincterotome mu ikoreshwa rya Endoscopic

1. Ingano y'umurambararo
Ubugari bwa sphincterotome muri rusange ni 6Fr, kandi igice cyo hejuru kigabanuka buhoro buhoro kikagera kuri 4-4.5Fr. Ubugari bwa sphincterotome ntibukeneye kwitabwaho cyane, ariko bushobora kumvikana ukoresheje guhuza uburebure bwa sphincterotome n'imbaraga zikora za endoscope. Ese hari undi mugozi uyobora ushobora gutangwa mu gihe sphincterotome ishyirwamo?
2. Uburebure bw'icyuma
Uburebure bw'icyuma bugomba kwitabwaho, muri rusange ni mm 20-30. Uburebure bw'icyuma giyobora bugena inguni y'icyuma n'uburebure bw'imbaraga mu gihe cyo gukata. Kubwibyo, uko icyuma kiba kirekire, niko "inguni" y'icyuma yegera icyerekezo cy'umubiri w'icyuma gifata umuyoboro wa pancreaticobiliary, bishobora koroha kugifata neza. Muri icyo gihe, insinga ndende cyane z'icyuma zishobora gutera amakosa ku gice cy'icyuma n'inyubako zigikikije, bigatera ingorane zikomeye nko gutobora, bityo hakabaho "icyuma gisobanutse" gihuye n'ibikenewe mu buryo bw'umutekano mu gihe cyujuje uburebure bwacyo.
3. Kumenya Sphincterotome
Kumenya sphincterotome ni ikintu cy'ingenzi cyane, ahanini kugira ngo byorohereze umukoresha gusobanukirwa no kumenya aho sphincterotome iherereye mu gihe cyo gukata mu buryo buto kandi bw'ingenzi, no kwerekana aho iherereye hamwe n'aho iherereye mu buryo bwizewe. Muri rusange, hazaba hariho imyanya myinshi nka "tangira", "tangira", "hagati" na "1/4" bya sphincterotome, aho igice cya mbere cya kane n'igice cyo hagati cy'icyuma gikoze mu buryo bw'ubwenge ari imyanya itekanye yo gukata, ikoreshwa cyane. Byongeye kandi, ikimenyetso cyo hagati cya sphincterotome ni radiopaque. Mu gihe cyo kugenzura X-ray, aho sphincterotome iherereye muri sphincter ishobora kumvikana neza. Muri ubu buryo, hamwe n'uburebure bw'icyuma cyagaragaye imbere yo kureba neza, birashoboka kumenya niba icyuma gishobora gukora icyuma gikata mu buryo bwizewe. Ariko, buri sosiyete ifite imico itandukanye mu gukora ibirango, bigomba kumvikana.
