I-HIFU - Ukhetho Olutsha Kwizigulane Ezinezihlunu Eziphakathi ukuya KweziPhambili

Intshayelelo ye-HIFU

I-HIFU, emeleI-Ultrasound egxile kuBunzima obuphezulu, sisixhobo sonyango esingenazo izifo esenzelwe ukunyanga iithumba eziqinileyo. Siphuhliswe ngabaphandi abavela kwiNationalUphando loBunjineliIzikoyezonyango ze-Ultrasoundngokubambisana neChongqing Medical University kunye neChongqing Haifu Medical Technology Co., Ltd. Phantse iminyaka engamashumi amabini yemizamo engapheliyo, iHIFU ifumene imvume yomthetho kumazwe angama-33 nakwiindawo zehlabathi kwaye ithunyelwe kumazwe angaphezu kwama-20. Ngoku isetyenziswa kwizicelo zonyango eizibhedlele ezingaphezu kwama-2,000 kwihlabathi liphela.Ukusukela ngoDisemba 2021, i-HIFU ibisetyenziswa ukunyangaamatyala angaphezu kwama-200,000yezifo ezingengobungozi nezimbi, kunye nezifo ezingaphezu kwezigidi ezi-2 ezingezizo iithumba. Le teknoloji iqatshelwa ngokubanzi ziingcali ezininzi ezidumileyo ekhaya nakwamanye amazwe njengomzekelo.unyango olungangenisi ntsholongwane indlela yokwelapha yanamhlanje.

Umgaqo Wonyango
Umgaqo osebenzayo we-HIFU (i-High-Intensity Focused Ultrasound) ufana nendlela ilanga elijoliswa ngayo ngelensi ecacileyo. Njengokukhanya kwelanga,Amaza e-ultrasound anokujoliswa aze angene ngokukhuselekileyo emzimbeni womntu.I-HIFU yiunyango olungangenisi ntsholongwaneukhetho olusebenzisa amandla angaphandle e-ultrasound ukugxila kwiindawo ezithile ekujoliswe kuzo ngaphakathi emzimbeni.Amandla agxininiswe ngamandla aphezulu ngokwaneleyo kwindawo yesilonda, afikelela kumaqondo obushushu angaphezu kwama-60 degrees Celsius.okomzuzwana. Oku kubangela i-coagulative necrosis, nto leyo ebangela ukufunxwa okanye ukuqhekeka kancinci kancinci kwezicubu ezifileyo.Okubalulekileyo kukuba, izicubu ezijikelezileyo kunye nokuhamba kwamaza esandi akonakaliswanga kule nkqubo.

Izicelo

I-HIFU iboniswe kwiindidi ezahlukeneyoizimila ezinobungozi, kuquka umhlaza wepancreatic, umhlaza wesibindi, umhlaza wezintso, umhlaza webele, iithumba ze-pelvic, ii-sarcomas zezicubu ezithambileyo, iithumba zethambo ezinobungozi, kunye neethumba ze-retroperitoneal. Ikwasetyenziselwa ukunyangaiimeko zesiniezifana ne-uterine fibroids, i-adenomyosis, i-breast fibroids, kunye nokukhulelwa kwamanxeba.

Kolu phononongo lweklinikhi olunamaziko amaninzi lonyango lwe-HIFU lwe-uterine fibroids olubhaliswe ngeqonga lokubhalisa le-World Health Organisation, i-Academician uLang Jinghe wasePeking Union Medical College Hospital wayesebenza njengososayensi oyintloko weqela lophando,Izibhedlele ezingama-20 zithathe inxaxheba, amatyala angama-2,400, kunye nokulandelelana kweenyanga ezingaphezu kwe-12Ezi ziphumo, ezipapashwe kwi-BJOG Journal of Obstetrics and Gynaecology enefuthe kwihlabathi liphela ngoJuni 2017, zibonisa ukuba ukusebenza kakuhle kwe-ultrasound ablation (HIFU) kunyango lwe-uterine fibroids kuhambelana notyando lwendabuko, ngelixa ukhuseleko luphezulu, ixesha lokuhlala kwesigulana esibhedlele lifutshane, kwaye ukubuyela kubomi obuqhelekileyo kukhawuleza.

Iingenelo zonyango

• Unyango olungangenisi ntsholongwane:I-HIFU isebenzisa amaza e-ultrasound, aluhlobo lwamaza oomatshini angena-ionizing. Ikhuselekile, kuba ayibandakanyi i-ionizing radiation. Oku kuthetha ukuba akukho mfuneko yokusika utyando, ukunciphisa ukwenzakala kwezicubu kunye nentlungu ehambelana nayo. Ayinayo ne-radiation, enokunceda ukuphucula amajoni omzimba.
• Unyango olusengqondweni: Izigulana zifumana unyango lwe-HIFU zivukile,kusetyenziswa kuphela i-local anesthesia okanye i-sedation ngexesha lenkqubo.Oku kunceda ukunciphisa iingozi ezinxulumene ne-anesthesia jikelele.
• Ixesha elifutshane lenkqubo:Ubude benkqubo buyahluka ngokuxhomekeke kwiimeko zesigulana ngasinye, ukusuka kwimizuzu engama-30 ukuya kwiiyure ezi-3. Iiseshoni ezininzi azisoloko ziyimfuneko, kwaye unyango lunokugqitywa kwiseshoni enye.
• Ukuchacha ngokukhawuleza:Emva konyango lwe-HIFU, izigulana ngokubanzi zinokuqala ukutya zize ziphume ebhedini zingadlulanga iiyure ezi-2. Uninzi lwezigulana lunokukhululwa ngosuku olulandelayo ukuba akukho ngxaki. Kwisigulana esiqhelekileyo, ukuphumla iintsuku ezi-2-3 kuvumela ukubuyela kwimisebenzi yesiqhelo yomsebenzi.
• Ukugcinwa kokuchuma: Izigulane zezifo zabasetyhini ezineemfuno zokuchuma zingakwaziZama ukukhulelwa kwangethuba emva kweenyanga ezi-6 emva konyango.
• Unyango oluluhlaza:Unyango lwe-HIFU luthathwa njengolunobuhlobo nokusingqongileyo kuba alunamonakalo we-radioactive kwaye luthintela iziphumo ebezingalindelekanga ezinobungozi ezinxulumene ne-chemotherapy.
• Unyango olungenazikrweqe kwiimeko zesini:Unyango lwe-HIFU kwiimeko zesini alushiyi zikrweqe zibonakalayo, nto leyo evumela abafazi ukuba baphile ngokuzithemba okukhulu.

Amatyala

Ityala 1: Umhlaza wepancreatic weSigaba IV one-metastasis enkulu (owesilisa, oneminyaka engama-54)

I-HIFU yasusa ithumba elikhulu le-pancreatic elingu-15 cm ngexesha elinye

Ityala lesi-2: Umhlaza wesibindi oyintloko (oyindoda, oneminyaka engama-52 ubudala)

Ukususwa kwe-Radiofrequency kwabonisa i-tumor eseleyo (i-tumor ekufutshane ne-inferior vena cava). I-tumor eseleyo yasuswa ngokupheleleyo emva kokubuyela umva kwe-HIFU, kwaye i-inferior vena cava yayikhuselekile kakuhle.
