Mosiyana ndi zomwe dzina lake likunena, the fibroscan si fiberoptic, kapena scanner. Ichi ndi chiyeso chomwe chimaphatikizapo quantifying the chiwindi fibrosis, pozindikira kuuma kwa minofu ya chiwindi. Ubwino wake ndikuti simuyenera kulowa mkati mwa thupi: fibroscan ndi mayeso osapweteka komanso osasokoneza. Fibroscan (lomwe kwenikweni ndi dzina laukadaulo wovomerezeka ndi kampani yaku France, Echosens) imatchedwanso ultrasonic impulse elastometry.

Chiwindi fibrosis ndi chifukwa cha angapo mavuto aakulu a chiwindi : uchidakwa, matenda a chiwindi, ndi zina zotero. Izi zimatsogolera ku mapangidwe a zipsera zomwe zimalowa m'malo mwa maselo owonongeka a chiwindi: iyi ndi fibrosis. Zimasokoneza kamangidwe ka chiwindi mwachilengedwe komanso mwantchito, ndipo kupita patsogolo kwake kungayambitse matenda a cirrhosis (minofu owopsa omwe amapezeka pachiwindi chonse).

Dokotala amachita fibroscan kuti awone kuopsa kwa chiwindi cha fibrosis. Mayesowa amapangitsanso kuyang'anira momwe akuyendera.

Mayesowa atha kugwiritsidwanso ntchito pa:

• kuyang'anira matenda a chiwindi pansi pa chithandizo
• kuyang'anira zovuta za chiwindi
• zindikirani zovuta pambuyo pake kuyika chiwindi
• zizindikiro chiwindi zotupa

Dziwani kuti kuyesa kwa hepatic fibrosis kungathenso kuchitidwa ndi chiwindi (kutenga ma cell a chiwindi) kapena kuyezetsa magazi, koma mayesowa ndi ovuta, mosiyana ndi fibroscan.

Njirayi ndi yopanda ululu komanso yofanana ndi ultrasound.  

The fibroscan imakhala ndi kugwiritsa ntchitoelastometry (kapena elastography) kugwedezeka koyendetsedwa ndi mphamvu: njira yomwe imagwiritsidwa ntchito poyesa kufalikira kwa chiwopsezo m'chiwindi ndikuyesa kukhazikika kwake. Mafundewa akamafalikira mwachangu, chiwindi chimakhala cholimba kwambiri, motero fibrosis imakulirakulira.

Kuti achite izi, dokotala amaika kafukufuku pakati pa nthiti pamwamba pa khungu la wodwalayo atagona chagada ndikuyika dzanja lamanja kumbuyo kwa mutu. Kufufuzako kumapanga mafunde otsika kwambiri (50 Hz) omwe amadutsa pachiwindi ndikutumiza funde ku probe. Chipangizochi chimawerengera liwiro ndi mphamvu ya echo iyi kuti awone kulimba kwa chiwindi.

Pafupifupi miyeso khumi yovomerezeka iyenera kutengedwa panthawi yowunika.

Mayeso amatenga mphindi 5 mpaka 15 zokha ndipo zotsatira zake zimakhala nthawi yomweyo.

Kuthamanga kwa chiwindi kumayesedwa mu kilopascal (kPa). Mtengo womwe wapezedwa umagwirizana ndi wapakatikati wa miyeso ya 10 ndi kuchuluka kwa ma oscillates pakati pa 2,5 ndi 75 kPa.

Chifukwa chake, kutengera kuwonongeka kwa chiwindi, kuchuluka kwa elasticity kumasiyanasiyana, fibrosis imakhala yodziwika bwino ndipo magawo osiyanasiyana amafotokozedwa:

• pakati pa 2,5 ndi 7, timalankhula za siteji F0 kapena F1: kusowa kwa fibrosis kapena fibrosis yochepa.

• Pakati pa 7 ndi 9,5, timalankhula za siteji F2: fibrosis yapakati

• pakati pa 9,5 ndi 14, timalankhula za siteji F3: fibrosis yovuta

• kupitirira 14, timalankhula za siteji F4: minofu ya chilonda imapezeka m'chiwindi chonse, ndipo matenda a cirrhosis alipo.

Kuti amalize matenda ake, dokotala akhoza kuyitanitsa mayeso ena monga a chiwindi kapena kusanthula magazi.
