Yini i-Radiofrequency Ablation yomdlavuza? Inhloso, Inqubo & Nemiphumela

I-Radiofrequency ablation (RFA) iyindlela yokwelapha engahlaseli kakhulu esebenzisa amandla okushisa ukubhubhisa amaseli omdlavuza. Cabanga ngayo njengendlela eqondile, eqondiwe yokuthi "ukupheka" izicubu zomdlavuza ngaphakathi, usebenzisa amandla kagesi aguqulwa abe ukushisa ngentambo encane efana nenaliti.

Lokhu kwelashwa kunikeza ithemba kubantu abaningi abanomdlavuza, ikakhulukazi uma ukuhlinzwa kungenzeki noma uma ufuna ukugwema izinqubo eziningi. Isebenza kahle kakhulu kuma-tumor amancane futhi ngokuvamile kungenziwa njengenqubo yeziguli eziphuthumayo, okusho ukuthi ungahamba ngosuku olufanayo.

Yini i-radiofrequency ablation?

I-Radiofrequency ablation isebenza ngokuletha ukushisa okulawulwayo ngqo kumaseli omdlavuza ngentambo ekhethekile. Ukushisa kufinyelela emazingeni okushisa angaba ngu-212°F (100°C), okubhubhisa izicubu zomdlavuza ngenkathi kunciphisa ukulimala ezindaweni ezinempilo ezizungezile.

Le nqubo isebenzisa uhlobo olufanayo lwamandla olunamandla emisakazo, kodwa lugxilwe futhi lulawulwa ukudala ukushisa okwelaphayo. Udokotela wakho uqondisa i-electrode encane ngesikhumba sakho ngqo kwi-tumor esebenzisa isiqondiso sokucabanga njengama-CT scan noma i-ultrasound.

Amaseli omdlavuza abhubhiswe ancibilika kancane kancane emzimbeni wakho emasontweni amaningana kuya ezinyangeni. Le nqubo iyimvelo futhi iphephile, ifana nendlela umzimba wakho obhekana ngayo nezinye izicubu ezilimele.

Kungani kwenziwa i-radiofrequency ablation?

I-RFA incomwa uma ingawelapha ngempumelelo umdlavuza wakho ngenkathi igcina izinga lempilo yakho. Ivame ukukhethwa kubantu abangabafaneleki kahle ukuhlinzwa ngenxa yobudala, ezinye izimo zempilo, noma indawo ye-tumor.

Udokotela wakho angase aphakamise i-RFA uma une-tumor ezingxenyeni zomzimba ezinjenge-liver, amaphaphu, izinso, noma amathambo. Ibaluleke kakhulu ekwelapheni umdlavuza wesibindi, womabili ama-tumor ayinhloko nalabo abasabalale kwezinye izingxenye zomzimba wakho.

Ngesinye isikhathi i-RFA isetshenziswa kanye nezinye izindlela zokwelapha ezifana ne-chemotherapy noma i-radiation therapy. Ingasiza futhi ekuphatheni izimpawu zomdlavuza, ikakhulukazi ubuhlungu bamathambo obangelwa ama-tumor asakhele emathanjeni akho.

Le nqubo isebenza kahle kakhulu kuma-tumor amancane kunamasentimitha angu-2 (5 cm) ububanzi. Ama-tumor amakhulu angase adinge izikhathi zokwelashwa eziningi noma ukuhlanganisa i-RFA nezinye izindlela.

Yini inqubo ye-radiofrequency ablation?

Inqubo ye-RFA ngokuvamile ithatha amahora angu-1-3 futhi yenziwa yi-interventional radiologist. Uzothola i-conscious sedation noma i-general anesthesia ukuze ikugcine ukhululekile ngesikhathi sokwelashwa.

Udokotela wakho uzohlanza futhi aqede isikhumba lapho kuzofakwa khona i-probe. Ebenzisa isiqondiso sesithombe sesikhathi sangempela, bazohola ngokucophelela i-electrode ngesikhumba sakho ngqo emthanjeni we-tumor.

Nakhu okwenzekayo ngesikhathi sokwelashwa kwangempela:

1. I-electrode ibekwe ngokuqondile ngaphakathi kwe-tumor
2. Amandla e-Radiofrequency alethwa imizuzu engu-10-30
3. Ukushisa kudala indawo yezicubu ezibhubhiswe ngaphandle kwe-probe
4. Izindawo eziningi ze-probe zingasetshenziswa kuma-tumor amakhulu
5. Ukucabanga kuqinisekisa ukwelashwa okuphelele kwendawo okuyiwa kuyo

Ngemva kokwelashwa, uzoqashwa endaweni yokululama amahora ambalwa. Abantu abaningi bathola kuphela ukungakhululeki okuncane, okungaphathwa ngemithi yokwelapha ubuhlungu engathengiswa ngaphandle kwemvume kadokotela.

Ungalungiselela kanjani i-radiofrequency ablation yakho?

Ukulungiselela kwakho kuzoxhomeka ekutheni yiliphi ilungu lomzimba eliphathwayo, kodwa ezinye iziqondiso ezijwayelekile zisebenza ezinqubweni eziningi ze-RFA. Ithimba lakho lezokwelapha lizohlinzeka ngemiyalelo ethile eyenzelwe isimo sakho.

Ngokuvamile uzodinga ukuyeka ukudla nokuphuza amahora angu-6-8 ngaphambi kwenqubo. Lokhu kuqapha kusiza ekuvikeleni izinkinga uma udinga i-general anesthesia noma i-conscious sedation.

Udkt. wakho uzobukeza imithi yakho yamanje futhi angase akucele ukuthi uyeke okwesikhashana eminye, ikakhulukazi ama-blood thinners afana ne-warfarin noma i-aspirin. Ungenzi lezi zinguquko ngaphandle kwesiqondiso sezokwelapha, njengoba eminye imithi idinga ukuyekiswa izinsuku ngaphambi kwenqubo.

Hlela ukuthi othile akuqhubele ekhaya ngemva kokwelashwa, njengoba imithi yokuthulisa izothinta ikhono lakho lokushayela ngokuphepha. Kufanele futhi uhlele ukuthi othile ahlale nawe amahora okuqala angu-24 ngemva kwenqubo.

Gqoka izingubo ezikhululekile, ezikhululekile futhi ususe ubucwebe noma izinto zensimbi ezingase ziphazamise imishini yokuthwebula izithombe. Ithimba lakho lezokwelapha lizohlinzeka ngegawuni yasesibhedlela yenqubo.

Ungawafunda kanjani imiphumela yakho ye-radiofrequency ablation?

Imiphumela ye-RFA ngokuvamile ihlolwa ngezifundo zokulandela ngemva kokuthwebula izithombe ezenziwa ngemva kwezinyanga eziyi-1-3 ngemva kokwelashwa kwakho. Lezi zithombe zibonisa ukuthi ngabe amaseli omdlavuza abhubhiswe ngempumelelo yini futhi zisiza ukuthola noma iyiphi inyama yesimila esasele.

Ukwelashwa okuphumelelayo kudala lokho odokotela abakubiza ngokuthi

Isebenza kangakanani i-radiofrequency ablation kumdlavuza?

Amazinga empumelelo e-RFA ayahluka ngokuya ngosayizi wesimila, indawo, nohlobo lomdlavuza, kodwa imiphumela iyonke ikhuthaza kakhulu. Kumasimila amancane esibindi (angaphansi kwamasentimitha angu-2), amazinga empumelelo avame ukudlula ama-90% ekubhujisweni okuphelele kwesimila.

Le nqubo isebenza kahle kakhulu kumdlavuza wesibindi wokuqala kanye nama-metastases esibindi avela emdlavuzeni we-colorectal. Amazinga empumelelo yamasimila emaphaphu nawo aphezulu, ikakhulukazi kumasimila amancane kunamasentimitha angu-1.5 ububanzi.

Izici eziningana zithonya ukuthi i-RFA isebenza kahle kangakanani esimweni sakho esithile:

• Usayizi wesimila - amasimila amancane anamazinga empumelelo aphezulu
