HIFU - Njira Yatsopano kwa Odwala Omwe Ali ndi Zotupa Zapakatikati mpaka Zapamwamba

Chiyambi cha HIFU

HIFU, chomwe chimaimiraHigh Intensity Focused Ultrasound, ndi chipangizo chachipatala chosagwiritsa ntchito mankhwala opangidwa kuti azichiza zotupa zolimba.Zapangidwa ndi ofufuza ochokera ku NationalKafukufuku wa EngineeringPakatiMankhwala a Ultrasoundmogwirizana ndi Chongqing Medical University ndi Chongqing Haifu Medical Technology Co., Ltd. Ndi pafupifupi zaka makumi awiri za khama mosatopa, HIFU yapeza kuvomerezedwa ndi malamulo m'mayiko 33 ndi zigawo padziko lonse lapansi ndipo yatumizidwa ku mayiko oposa 20.Tsopano ikugwiritsidwa ntchito pazachipatala muzipatala zopitilira 2,000 padziko lonse lapansi.Pofika Disembala 2021, HIFU yakhala ikugwiritsidwa ntchito kuchizamilandu yopitilira 200,000za zotupa zoyipa komanso zowopsa, komanso milandu yopitilira 2 miliyoni ya matenda omwe si a chotupa.Ukadaulo uwu umadziwika ndi akatswiri ambiri odziwika kunyumba ndi kunja ngati chitsanzo chabwinomankhwala osasokoneza njira mu mankhwala amakono.

Mfundo ya Chithandizo
Mfundo yogwira ntchito ya HIFU (High-Intensity Focused Ultrasound) ikufanana ndi momwe kuwala kwa dzuwa kumayendera kudzera mu lens convex.Monga kuwala kwa dzuwa,mafunde a ultrasound amathanso kuyang'ana ndikulowa bwino m'thupi la munthu.HIFU ndimankhwala osasokonezanjira yomwe imagwiritsa ntchito mphamvu zakunja za ultrasound kuyang'ana malo enieni omwe ali mkati mwa thupi.Mphamvuyi imakhazikika mpaka kulimba kokwanira pamalo otupa, kufika kutentha kuposa madigiri 60 Celsius.kwa mphindi.Izi zimayambitsa coagulative necrosis, zomwe zimapangitsa kuti pang'onopang'ono mayamwidwe kapena mabala a necrotic minofu.Chofunika kwambiri, minyewa yozungulira ndikudutsa kwa mafunde akumveka sikuwonongeka panthawiyi.

Mapulogalamu

HIFU amasonyezedwa zosiyanasiyanazotupa zowopsa, kuphatikizapo khansa ya m'mapapo, khansa ya chiwindi, khansa ya impso, khansa ya m'mawere, zotupa za m'chiuno, ma sarcomas a minofu yofewa, zotupa zowononga mafupa, ndi zotupa za retroperitoneal.Amagwiritsidwanso ntchito pochizamatenda achikazimonga uterine fibroids, adenomyosis, bele fibroids, ndi mimba zipsera.

Pa kafukufuku wachipatala wa HIFU wa uterine fibroids wolembetsedwa kudzera pa nsanja yolembetsa ya World Health Organisation, Academician Lang Jinghe wa ku Peking Union Medical College Hospital payekha adakhala wasayansi wamkulu wa gulu lofufuza,Zipatala 20 zidatenga nawo gawo, milandu 2,400, yopitilira miyezi 12 yotsatiridwa.Zomwe zapezedwa, zofalitsidwa mu BJOG Journal of Obstetrics and Gynecology padziko lonse lapansi mu JUNE 2017, zikuwonetsa kuti mphamvu ya ultrasonic ablation (HIFU) pochiza uterine fibroids imagwirizana ndi opaleshoni yachikhalidwe, pomwe chitetezo chimakhala chokwera, chipatala cha wodwalayo. ndi lalifupi, ndipo kubwerera ku moyo wabwinobwino kumathamanga.

Ubwino wa Chithandizo

• Chithandizo chosawononga:HIFU imagwiritsa ntchito mafunde a ultrasound, omwe ndi mtundu wa mafunde osagwiritsa ntchito ionizing.Ndizotetezeka, chifukwa sizimaphatikizapo cheza cha ionizing.Izi zikutanthauza kuti palibe chifukwa chopangira opaleshoni, kuchepetsa kupwetekedwa kwa minofu ndi ululu wogwirizana nawo.Ilinso yopanda ma radiation, yomwe ingathandize kukonza chitetezo chamthupi.
• Chithandizo chozindikira: Odwala amalandila chithandizo cha HIFU ali maso,ndi anesthesia wamba kapena sedation yokha yomwe imagwiritsidwa ntchito panthawiyi.Izi zimathandiza kuchepetsa zoopsa zomwe zimagwirizanitsidwa ndi anesthesia wamba.
• Nthawi yochepa ya ndondomeko:Kutalika kwa njirayi kumasiyanasiyana malinga ndi momwe wodwalayo alili, kuyambira mphindi 30 mpaka maola atatu.Magawo angapo nthawi zambiri sakhala ofunikira, ndipo chithandizocho chimatha pagawo limodzi.
• Kuchira mwachangu:Pambuyo pa chithandizo cha HIFU, odwala amatha kuyambiranso kudya ndikudzuka pasanathe maola awiri.Odwala ambiri amatha kutulutsidwa tsiku lotsatira ngati palibe zovuta.Kwa wodwala wamba, kupumula kwa masiku 2-3 kumalola kubwereranso kuntchito zachizolowezi.
• Kuteteza chiberekero: Odwala achikazi omwe ali ndi zofunikira zakubala angatheyesetsani kutenga pakati patatha miyezi 6 mutalandira chithandizo.
• Green therapy:Chithandizo cha HIFU chimaonedwa kuti n'chogwirizana ndi chilengedwe chifukwa sichiwononga ma radioactive ndipo chimapewa zotsatira zoyipa zomwe zimagwirizanitsidwa ndi chemotherapy.
• Chithandizo chopanda chiwopsezo cha matenda achikazi:Chithandizo cha HIFU cha matenda achikazi chimasiya zipsera zowoneka, zomwe zimalola amayi kuti achire ndi chidaliro chowonjezereka.

Milandu

Mlandu 1: Gawo IV khansa ya kapamba yokhala ndi metastasis yayikulu (mwamuna, 54)

HIFU idatulutsa chotupa chachikulu cha pancreatic 15 cm nthawi imodzi

Mlandu 2: Khansara yachiwindi yoyambirira (mwamuna, wazaka 52)

Kutuluka kwa radiofrequency kumawonetsa chotupa chotsalira (chotupa pafupi ndi inferior vena cava).Chotupa chotsaliracho chinachotsedwa kwathunthu pambuyo pa kubwezeretsedwa kwa HIFU, ndipo otsika kwambiri a vena cava anali otetezedwa bwino.
