Ngā Taputapu ERCP 3 Lumen Whakamahinga Kotahi Sphincterotome mō te Whakamahinga Endoscopic

1. Te whānui
Ko te whānui o te sphincterotome he 6Fr te whānui, ā, ka whakaitihia haeretia te pito ki te 4-4.5Fr. Kāore e nui te aro ki te whānui o te sphincterotome, engari ka taea te mārama mā te whakakotahi i te whānui o te sphincterotome me ngā forceps mahi o te endoscope. Ka taea te tuku i tētahi atu waea ārahi i te wā e whakatakotoria ana te sphincterotome.
2. Te roa o te mata
Me aro nui ki te roa o te mata, arā, 20-30 mm te nuinga. Ko te roa o te waea ārahi e whakatau ana i te koki pewa o te maripi pewa me te roa o te kaha i te wā e tapahia ana. Nō reira, ko te roa o te waea maripi, ko te tata atu o te "koki" o te pewa ki te ahunga anatomical o te ngongo ngongo pancreaticobiliary, ka māmā ake pea te whakauru angitu i te ngongo. I taua wā anō, ko ngā waea maripi roa rawa ka raru pea te tapahi hē o te sphincter me ngā hanganga e karapoti ana, ka hua ake he raruraru nui pēnei i te poka, nō reira he "maripi atamai" e tutuki ana i ngā hiahia haumaru me te tutuki i te roa.
3. Te tautuhi i te sphincterotome
He mea tino nui te tautuhi i te sphincterotome, ko te mea nui kia māmā ake te mārama me te tautuhi i te tūranga o te sphincterotome i te wā e tapahia ana, e tapahia ana, me te tohu i te tūranga noa me te tūranga tapahi haumaru. I te nuinga o te wā, ka tohua ētahi tūranga pēnei i te "tīmatanga", "tīmatanga", "waenganui" me te "1/4" o te sphincterotome, ko te 1/4 tuatahi me te waenganui o te maripi atamai he tūranga haumaru mō te tapahi, he mea whakamahi noa. Hei tāpiri, he radiopaque te tohu waenga o te sphincterotome. I raro i te aroturuki hihi-X, ka taea te mārama pai ki te tūranga whanaunga o te sphincter i roto i te sphincter. Mā tēnei, me te roa o te maripi e kitea ana i raro i te tirohanga tika, ka taea te mōhio mēnā ka taea e te maripi te tapahi haumaru i te sphincter. Heoi, he rerekē ngā tikanga waitohu o ia kamupene i roto i te hanga waitohu, me mārama.
