Txoj hlab dej ntawm lub ncauj tsev menyuam, raws li cov ntsiab lus ntawm kev tshawb fawb, cuam tshuam txog li 44% ntawm cov poj niam ntawm cov me nyuam muaj hnub nyoog. Qhov tseeb tias txoj hlab ntawm lub ncauj tsev menyuam yog thaum muaj kev kawm tsis txaus ntseeg muaj peev xwm ua tau rau txoj kev loj hlob ntawm kheesxaws ncauj tsev menyuam tau muaj pov thawj.
Yaig yog ib qho kho raws faim fab hauv qhov epithelium. Thaum xub thawj, thaum nws tsis tuaj yeem kuaj xyuas cov ncauj tsev menyuam nrog cov khoom siv roj, qhov chaw hu ua "erosion" hu ua "defect" hauv qhov chaw mos ntawm lub ncauj tsev me nyuam, uas yog lub qhov muag pom ntawm lub qhov liab dawb.
Thaum cov yeeb ncuab tshwm sim, nws pom tau hais tias nyob rau hauv feem ntau ntawm cov neeg mob cov kab mob hauv lub ncauj tsev me nyuam tsis yog mob tiag tiag, tiam sis kis ntawm cylindrical epithelial cov ntaub so ntswg ntawm lub ncauj tsev menyuam hauv qhov chaw mos. Yog li, nyob rau hauv niaj hnub gynecology, lub sij hawm "erosion ntawm lub tsev me nyuam" yog siv heev tsis tshua muaj, thiab nws tau hloov los ntawm lub sij hawm " poj niam cervical ectopia " los yog "pseudo-erosion".
Lub plab zawv ntawm lub ncauj tsev menyuam yog dab tsi?
Nws muaj qhov tseeb ntawm qhov ncauj ntawm qhov ncauj tsev menyuam. Hauv me me, txoj hlab ntawm lub ncauj tsev menyuam txawv ntawm 0.2 centimeters mus rau 2 centimeters los yog ntau dua.
- Qhov tseeb ntawm txoj hlab ntawm lub ncauj tsev menyuam yog qhov ua txhaum cai ntawm lub hlwb ntawm qhov epithelium (zoo ib yam mob me me), nws ua rau nws tus kheej zoo tom qab tshem tawm qhov kev xav tau. Qhov tseeb erosion txhais tias yog me ntsis cov xim liab ntawm lub qhov ncauj ntawm lub ncauj tsev menyuam.
- Kev tsis zoo ntawm qhov ncauj ntawm qhov ncauj tsev menyuam ( pseudo-erosion , ectopia) yog qhov txawv ntawm lub vev xaib multithayered epithelium ntawm qhov chaw mos ntawm qhov chaw mos ntawm lub hlwb ntawm cylindrical epithelium, feem ntau nyob hauv lub tsev menyuam. Nrog no pathology, yog tsis muaj kev kho raws nyob rau hauv lub epithelium nws tus kheej. Qee lub hlwb "tsis nyob hauv lawv qhov chaw."
Hauv colposcopy, pseudo-erosion txhais tias yog thaj ntawm tsis zoo nkauj, xim daj liab, npog ntev los yog papillae (muaj lub peculiar "velvety appearance)). Cov xim liab qaim yog kis los ntawm cov hlab ntsha radiating ntawm lub txheej ntawm cylindrical epithelium. Ib ncig ntawm pseudo-yaig, raws li txoj cai, cov cheeb tsam ntawm xim grey xim (multilayered flat epithelium) raug pom.
Cov hlwb ntawm cov cylindrical thiab multilayered planar epithelium yog tus qauv qog rau lub ncauj tsev menyuam, tab sis nyob rau hauv ntau cov neeg mob pathological: iodine-negative zones, cov chaw dawb (leukoplakia), cov qauv zoo li mos mos tuaj yeem tshwm sim. Cov kab mob pathological yog ib qho kev tsis zoo thiab muaj peev xwm ua rau muaj kev sib daj sib deev.
Cov tsos ntawm erosions sib txawv nyob ntawm seb qhov loj ntawm qhov kho raws:
- me me yaig (tsis pub tshaj 1 centimeter hauv kab);
- nruab nrab (inch ntawm 1 mus rau 2 centimeters);
- loj yaig (ntau tshaj 2 centimeters).
Kev faib tawm ntawm qhov tawm los ntawm qhov loj me yog qhov tseem ceeb tshaj plaws rau kev soj ntsuam, vim hais tias txoj kev xaiv ntawm txoj kev kho mob nyob ntawm qhov no. Cov kab mob me me ntawm mucosa tuaj yeem kis tau ntawm nws tus kheej, thiab kev laus thiab loj me me feem ntau yuav tsum kho txoj kev kho mob, nrog rau kev phais kev phais mob ntawm lub qhov ncauj ntawm qhov ncauj tsev menyuam.
