Liver biopsy yog txoj kev kub-txheej txheem rau kev kuaj xyuas kab mob siab, ntsuas qib ntawm daim siab fibrosis thiab coj kev txiav txim siab kho mob. Ntawm cov koob tshuaj biopsy ntau yam, Menghini daim siab biopsy koob tau siv dav thoob ntiaj teb rau ntau tshaj li ib nrab xyoo pua txij li nws tsim nyob rau xyoo 1958 los ntawm Italian tus kws kho mob Giorgio Menghini, ua tsaug rau nws cov qauv tsim, kev ua haujlwm zoo thiab kev ruaj ntseg profile. Nws cov thev naus laus zis evolution sawv cev rau keeb kwm ntawm kev hloov pauv tshiab los ntawm phau ntawv qhia kev xav mus rau kev sib sib zog nqus nrog cov duab kos duab niaj hnub.

Classic Menghini Needle: Cov Ntsiab Cai thiab Kev Tsim Nyog

Lub tswv yim tsim qauv tseem ceeb ntawm koob Menghini nyob hauvceev, kev nyab xeeb thiab tsawg invasiveness. Qhov tseem ceeb ntawm qhov tsis zoo-siab aspiration biopsy koob, nws cov qauv classic muaj lub ntsej muag ntse-beveled, hollow cannula, tshem tau cov stylet (kom kaw lub koob lumen thaum puncture thiab tiv thaiv kev nkag mus ntawm cov ntaub so ntswg tsis yog lub hom phiaj), thiab ib qho txuas rau txuas lub koob txhaj tshuaj los ua kom lub siab tsis zoo.

Nws txoj kev khiav hauj lwm yog ingenious thiab npaum. Nyob rau hauv ultrasound lossis CT kev taw qhia, rab koob yog punctured sai heev los ntawm daim siab capsule. Lub syringe plunger yog ces tshem tawm sai sai los tsim kom muaj zog instantaneous tsis zoo siab, uas rub daim siab cov ntaub so ntswg mus rau hauv lub cannula lumen thaum lub ntse ntug ntawm lub taub hau txiav cov ntaub so ntswg. Cov koob tshuaj biopsy raug tshem tawm sai sai thaum tswj qhov tsis zoo, ua rau lub cev tsis zoo cylindrical ntawm daim siab cov ntaub so ntswg. Tag nrho cov txheej txheem feem ntau ua tiav hauv 1-2 vib nas this.

Qhov zoo ntawm qhov kev tsim no yog pom tseeb:

Kev ua haujlwm nrawm: Ib qho puncture retrieves txaus cov qauv, shortening lub koob lub sij hawm nyob rau hauv lub cev.

Tsawg kawg kev raug mob: Raws li nws tso siab rau kev thov ntau dua li kev txiav, nws theoretically ua rau tsis tshua muaj parenchymal laceration dua li txiav-hom biopsy koob, muaj peev xwm txo qis los ntshav txaus ntshai.

Cov qauv zoo: Cov ntaub so ntswg uas tau txais feem ntau tsis zoo thiab tsis tu ncua, tsim nyog rau kev kuaj mob histopathological nrog rau kev ntsuam xyuas ntawm cov kab mob hepatic lobular architecture, inflammatory grading thiab fibrosis staging.

Kev sib piv: Menghini Needle vs. Tru-Cut Needle

Yuav kom nkag siab txog cov xwm txheej ntawm rab koob Menghini, nws yuav tsum muab piv nrog rau lwm yam tseem ceeb: rab koob Tru-Cut (los yog rab koob txiav hom). Lub Tru-Cut koob muaj ib lub cannula sab nraud nrog lub ntsej muag ntse thiab ib qho stylet sab hauv uas muaj qhov tsis zoo nyob rau pem hauv ntej. Thaum lub sijhawm ua haujlwm, cov stylet sab hauv yog siab ua ntej kom muab cov ntaub so ntswg rau hauv qhov kev txiav txim siab, ua raws li kev nce qib sai ntawm cov cannula sab nraud kom txiav cov ntaub so ntswg hauv qhov thais.

Qhov sib txawv tseem ceeb ntawm ob yog raws li hauv qab no:

• Sampling mechanism: Lub koob Menghini nyob ntawm qhov kev xav tsis zoo; Lub Tru-Cut koob tso siab rau kev txiav tshuab.
• Specimen yam ntxwv: Cov ntaub so ntswg uas tau los ntawm rab koob Menghini yog nyias thiab ntev dua, qee zaum me ntsis deformed los ntawm qhov tsis zoo; cov los ntawm Tru-Cut koob yog tuab thiab luv nrog ntau cov qauv zoo khaws cia, tshwj xeeb tshaj yog haum rau daim siab nrog cov tawv nqaij tawv los yog mob fibrosis.
• Kev ua haujlwm nyuaj thiab txaus ntshai: Raws li kev lig kev cai, koob Menghini tau suav tias yooj yim dua thiab nrawm dua los ua haujlwm nrog kev pheej hmoo los ntshav qis dua. Lub koob Tru-Cut yuav tsum tau ua ob-kauj ruam nrog txoj kev kawm nkhaus, xav kom muaj kev tswj hwm tus neeg ua haujlwm siab dua thiab ceev faj ntau dua rau cov neeg mob uas muaj kev ua haujlwm tsis zoo ntawm coagulation.

Niaj hnub Hloov Kho thiab Evolution

Classic Menghini koob yog feem ntau rov siv tsis tau cov khoom siv hlau uas yuav tsum tau ua kom huv thiab ua kom tsis muaj menyuam. Nrog kev txhim kho cov qauv kev nyab xeeb kev kho mob thiab kev siv cov khoom siv ib leeg siv dav, cov koob Menghini niaj hnub tau hloov mus rau hauv ib qho khoom siv tsis muaj menyuam. Cov neeg tsim khoom tau qhia ntau yam kev ua kom zoo raws li kev tsim qauv classic:

• Koob tip design: Optimized bevel lub kaum sab xis thiab sharpness kom txo tau puncture kuj thiab cov ntaub so ntswg raug mob.
• Kev hloov khoom dua tshiab: Kev siv cov qib siab kho mob-qib stainless hlau los xyuas kom meej rigidity thiab biocompatibility. Titanium alloys yog siv nyob rau hauv ib co high-end khoom rau txhim kho MRI compatibility.
• Diversified specifications: Cov koob sib txawv ntawm qhov ntev (feem ntau yog 15-20 cm) thiab ntsuas ntsuas (piv txwv li, 16G, 18G) muaj rau cov neeg mob sib txawv ntawm lub cev thiab cov kev xav tau kho mob (xws li, cov koob 18G zoo dua rau kev siv menyuam yaus).
• Kev sib xyaw ua ke thiab kev siv yooj yim: Ntau yam khoom siv niaj hnub no muaj cov khoom sib txuas ua ntej lossis cov koob txhaj tshuaj / cov khoom siv tsis zoo los ua kom yooj yim cov txheej txheem thiab txhim kho cov qauv.

Kev sib tw thev naus laus zis ntawm cov neeg tsim khoom

Ntau lub tuam txhab kho mob thoob ntiaj teb tsim cov koob tshuaj Menghini-style daim siab biopsy. Tshaj li cov khoom lag luam nyob sab Europe thiab Asmeskas, Suav cov tuam txhab sawv cev los ntawm Manners Technology tau tshwm sim nrog cov khoom muaj peev xwm ua tau zoo. Cov neeg tsim khoom xws li Manners Technology tsis yog tsuas yog cov khoom lag luam tshwj xeeb xwb tab sis kuj tseem muaj cov kev pabcuam customized, kho qhov tsis xws li rab koob ntev, txoj kab uas hla thiab lub taub morphology kom tau raws li cov kev cai tshwj xeeb ntawm tsev kho mob lossis cov chaw tshawb fawb. Xws li kev hloov pauv yog qhov tseem ceeb rau kev tshawb fawb tshwj xeeb hauv chaw kho mob lossis tswj cov teeb meem nyuaj.

Tsis tas li ntawd, qee cov tuam txhab lag luam tau ua ke cov koob tshuaj Menghini nrog cov cuab yeej siv hluav taws xob tsis siv neeg los tsim cov phom ib nrab tsis siv neeg biopsy. Cov cuab yeej no tsim qauv thiab ua kom nrawm nrawm thiab ua rau lub siab ua haujlwm, txo qis kev pheej hmoo tshwm sim los ntawm kev hloov pauv hauv cov txheej txheem tswj hwm, thiab tshwj xeeb tshaj yog rau cov kws kho mob tshiab.

Xaus

Los ntawm cov qauv qub los ntawm Giorgio Menghini mus rau niaj hnub no cov khoom siv kho mob tau zoo thiab muaj kev nyab xeeb, kev hloov pauv ntawm Menghini daim siab biopsy koob embodies txoj cai nyob mus ib txhis uas kev kho mob xav tau kev hloov kho thev naus laus zis. Txawm hais tias cov txheej txheem kev kuaj mob uas tsis muaj kev cuam tshuam tshwm sim (xws li, ntu ntu elastography) tuaj yeem hloov pauv biopsy hauv qee qhov xwm txheej, kev kuaj mob histopathological tseem tsis tuaj yeem hloov pauv rau qhov kev kuaj pom tseeb, kev ntsuam xyuas ntawm kev mob rwj thiab kev taw qhia ntawm kev kho kom raug. Featuring classic tsim, high efficiency thiab kev cia siab rau, lub koob Menghini tseem tuav ib qho tseem ceeb heev txoj hauj lwm nyob rau hauv lub diagnostic armamentarium ntawm hepatology. Nyob rau hauv lub neej yav tom ntej, nrog rau kev nce qib hauv cov ntaub ntawv science thiab minimally invasive technologies, nws yuav txuas ntxiv mus rau kev nyab xeeb dua, precision thiab txawj ntse.
