Ka tukuna e tēnei pūwero ngaru oro auau-nui e hoki ana ki te hanga whakaahua taipitopito o ngā paparanga kiko me ngā hanganga. Nā te mea e tata ana te ultrasound ki ngā okana e tirotirohia ana, he mārama, he tika hoki ngā whakaahua.

Ka taea e te EUS te tirotiro i ngā paparanga kiko e kore e kitea e ētahi atu whakamātautau whakaahua. He mea tino whai hua mō te titiro ki te pancreas, ngā awa pāpā, me ngā paparanga hōhonu o ngā pakitara ara kūnatu. Nō reira he taputapu pai rawa atu mō te kite i ngā huringa wawe, i ngā rerekētanga rānei e kore e puta i ngā karapa CT, i ngā MRI rānei.

He aha te take i mahia ai te ultrasound endoscopic?

Ka tohutohu pea tō tākuta i te EUS ina hiahia rātou ki te titiro hōhonu atu ki ngā tohumate, ki ngā kitenga rānei e hiahia ana kia āta tirohia tō pūnaha kūnatu me ngā okana e tata ana. He tino whai hua tēnei tikanga mō te tātai i ngā āhuatanga e pā ana ki te pūkahukahu, ngā awa pāpā, ki ngā paparanga hōhonu rānei o tō ara kūnatu.

Ngā take noa mō te EUS ko te aromatawai i te mamae puku kāore i te mārama, te tirotiro i ngā pūmua, i ngā pūpū rānei o te pūkahukahu, me te whakatau i te wāhanga o ētahi momo mate pukupuku. Ka āwhina te tikanga ki te whakatau mēnā he pai, he kino rānei te tipu, ā, ki te whai mate pukupuku, te whānuitanga o tōna horapa.

He mea nui hoki te EUS mō te ārahi i ngā koiora ina hiahiatia ngā tauira kiko mai i ngā wāhi uaua ki te tae atu. Ka taea e te ārahitanga ultrasound te tākuta ki te whai i ngā wāhi e mōrearea ana, me te kohikohi tauira i runga i te haumaru. I tua atu, ka āwhina i te aromatawai i ngā raruraru o te awa pāpā, te tirotiro i te ngaronga taumaha kāore i te mārama, me te aromatawai i ngā āhuatanga mumura o te pūkahukahu.

Me whai EUS ētahi tāngata ki te aroturuki i ngā āhuatanga e mōhiotia ana i te wā. Hei tauira, ki te whai pūpū pūkahukahu koe, ka whakamahi pea tō tākuta i te EUS ki te aroturuki i ngā huringa o te rahi, te āhua rānei. Ka whakamahia hoki ki te aromatawai i ngā urupare maimoatanga i ētahi mate pukupuku, me te whakamahere i ngā tikanga pokanga.

He aha te tikanga mō te ultrasound endoscopic?

Ko te tikanga EUS te nuinga ka 30 ki te 90 meneti, ā, ka mahia i te nuinga o te wā hei tikanga tūroro waho. Ka tae koe ki te hōhipera, ki te whare haumanu rānei i muri i te whai i ngā tohutohu whakarite, e uru ana te nohopuku mō te 8-12 haora i mua.

Ka uru pea tēnei ki te whakapakoko anō, ngā whakamātautau atu, te tuku rānei ki ngā tohunga. Me mōhio koe ki te wā me te hiranga o ngā tiaki aroturuki e tūtohutia ana.

Ngā pātai e pātai pinepine ana mō te ultrasound endoscopic

Q.1 He pai te whakamātautau ultrasound endoscopic mō te mate pukupuku pancreatic?

Āe, e whakaarohia ana ko te EUS tētahi o ngā whakamātautau pai rawa atu mō te kite me te arotake i te mate pukupuku pancreatic. Ka taea e ia te tautuhi i ngā puku iti e kore pea e puta mārama i runga i ngā karapa CT, i ngā MRI rānei, ina koa ko ngā mea iti iho i te 2 henimita. Ko te tata o te pūoro ultrasound ki te pancreas e whakarato ana i te kounga whakaahua pai.

He mea nui te EUS mō te whakatū i te wāhi o te mate pukupuku o te pāhau i te wā i kitea ai. Ka taea e ia te whakaatu mēnā kua horapa te mate pukupuku ki ngā oko toto tata, ngā pona rāpoi, ētahi atu okana rānei, he mōhiohio nui tēnei mō te whakamahere i te rongoā. Mā tēnei mōhiohio whakatū wāhi e āwhina ngā tākuta ki te whakatau mēnā ka taea te pokanga, me te momo rongoā e tino whai hua ana.

Q.2 Ko te ultrasound endoscopic hē tonu te tikanga he mate pukupuku?

Kāore, kāore te kitea hē o te EUS e tohu tonu ana he mate pukupuku. He maha ngā āhuatanga ka puta te ahua hē i runga i te ultrasound, tae atu ki ngā pūpū ngawari, te mumura, ngā mate, me ngā tipu kāore i te mate pukupuku. Inaha, ko te nuinga o ngā kitenga hē ka puta he āhuatanga ngawari e hiahia ana ki te aroturuki, kaua ki te rongoā kaha.

Hei tauira, he mea noa te kitea o ngā pūpū o te pāhau i te wā o te EUS, ā, ko te nuinga o ēnei he ngawari, kāore hoki e hiahia rongoā. Ka taea hoki e te pancreatitis tawhito, ngā kōhatu ngongo pūngāwerewere, me ngā āhuatanga mumura te hanga i ngā ahua hē kāore he pānga ki te mate pukupuku. Koinei te take e hiahiatia ana te tauira kiko me ētahi atu whakamātautau ki te whakatau i te āhua tika o ngā kitenga hē.

Q.3 E hia te roa ki te tiki i ngā hua ultrasound endoscopic?

Ko ngā kitenga tuatahi mai i te whakamātau tirohanga ka wātea i roto i ngā rā torutoru i muri i tō tukanga. Ka taea e tō tākuta te kōrero ki a koe mō ngā hē kitea, ngā kitenga noa rānei i muri i te arotake i ngā whakaahua me ngā tuhipoka tukanga.

Heoi, mēnā i tangohia ngā tauira kiko i te wā o te tukanga, ka roa te 5-7 rā pakihi ki te tiki i ngā hua katoa. Ka roa pea ētahi whakamātautau motuhake i runga i ngā tauira kiko, tae atu ki te rua wiki i ētahi wā. Mā tō rōpū hauora koe e whakamōhio mō te wā e tūmanakohia ana mō tō āhuatanga motuhake, ā, ka whakapā atu ki a koe i te wā e wātea ana ngā hua katoa.

Q.4 Ka taea e au te kai noa i muri i te ultrasound endoscopic?

Ka taea e koe te hoki ki te kai i te wa e ngaro ana nga paanga o te rongoa whakamaimoa, a kua tino mataara koe, te tikanga 2-4 haora i muri i te tikanga. Me timata ki nga wai marama iti penei i te wai, i te wai aporo ranei kia mohio ai ka taea e koe te horomia marie me te kore e riri te korokoro.

Mena ka pai koe ki nga wai, ka taea e koe te anga whakamua ki nga kai ngawari, katahi ka kai noa.

Me whai tonu i nga tohutohu motuhake i muri i te tikanga i tukuna e to roopu hauora.

Q.5 He tika ake te ultrasound endoscopic i te karapa CT?

He whakamatautau taapiri te EUS me nga karapa CT, he painga motuhake kei ia tangata. Ko te EUS te nuinga he tika ake mo te arotake i te pancreas, nga ngongo bile, me nga paparanga o te pakitara o te ara whakatipu na te mea ka tata atu te tirotiro ultrasound ki enei hanganga i te wa e taea ana e te ahua o waho.

Mo te kite i nga puku pancreatic iti, te uru mai o te pona lymph, me te arotake i te hohonutanga o te whakaekenga mate pukupuku, he pai ake te EUS i nga karapa CT. Heoi, he pai ake nga karapa CT mo te tirohanga whanui o te puku katoa me te kite i te horapa tawhiti o te mate. He maha nga taakuta e whakamahi ana i nga whakamatautau e rua i te taha ki te tiki i te pikitia tino oti, na te mea ka hoatu e ia nga korero whai hua engari rereke.
