Te tiaki i te hongere mahi, te mahi māmā

He tino pai te pupuri i te āhua
He āwhina whai hua ki te whakaoti rapanga mō te mauheretanga kōhatu

Ko ngā tikanga ERCP hei tango i ngā kōhatu awaawa noa e rua ngā tikanga: te poihau, te kete, me ētahi tikanga i ahu mai. I te whanaketanga o te hangarau, ko te whiriwhiri i te kete, i te poihau rānei, e whakawhirinaki ana ki te kaiwhakahaere. Ko te wheako, ko te hiahia, hei tauira, ko ngā kete tango kōhatu te mea tuatahi e whakamahia ana i Ūropi me Hapani, nā te mea he kaha ake te kete tango kōhatu, he kaha ake hoki te kukume i te poihau, engari nā tōna hanganga, he uaua ki te hopu i ngā kōhatu iti i te kete tango kōhatu, inā koa kāore i te rawaka te tapahi o te uma, he nui ake rānei ngā kōhatu i te mea e tumanakohia ana, ka taea e te tango kōhatu kete te whakapūmau i te kōhatu. I runga i ēnei āhuatanga, ko te tikanga tango kōhatu poihau te mea nui ake pea te whakamahi i te United States.
He maha ngā rangahau kua whakaatu he rite tonu te angitu o ngā tikanga tango kohatu whatu me te kohatu poihau ina iti iho i te 1.1 cm te whānui o te kohatu, ā, kāore he rerekētanga tatauranga i roto i ngā raruraru. Ina uaua te tango i ngā kohatu mai i te kete, ka taea te whakamahi i te tikanga laser lithotripsy hei whakaoti rapanga i te tango kohatu uaua. Nō reira, i roto i te mahi tuturu, me whai whakaaro whānui ki te rahi o te kohatu, te wheako o te kaiwhakahaere me ētahi atu āhuatanga, ā, me whiriwhiri he tikanga tango kohatu e tika ana.
