Tubular adenoma dysplasia qib 1-2

plab hnyuv pathologies yog pom nyob rau hauv muaj coob tus neeg. Ib tug tshwj xeeb tshaj yog txaus ntshai tus kab mob ntawm lub cev yog pom tias yuav phem transformation ntawm lub epithelium. Cancer ntawm cov nyuv thiab qhov quav yog ib tug ntawm cov uas lub chaw nyob rau hauv cov qauv ntawm cov oncological pathologies. Tus kab mob feem ntau ua rau tus tuag ntawm cov neeg mob. Nws yog yog li ntawd ib qho tseem ceeb lub sij hawm los xyuas cov neeg mob uas muaj ua ntej lub phem kev loj hlob ntawm lub hlwb. Ib tug ntawm cov pathologies yog tubular adenoma (polyp). Txawm tias muaj tseeb hais tias nws muaj ib txwm epithelial hlwb, nws degeneration nyob rau hauv lub qog tej zaum yuav tshwm sim. Yog li ntawd, raws li qhov kev nrhiav kom tau ntawm plab hnyuv adenomas yeej ib txwm yuav tsum tau sib tham oncologist. Nyob rau hauv feem ntau tus neeg mob, yuav tsum tau muab tshem tawm surgically kev kawm ntawv.

Yuav ua li cas yog lub tubular adenoma ntawm cov nyuv?

Benign qog ntawm txoj hnyuv yog hom. Nyob rau hauv tsawg zaus, lawv coj tsis zoo thiab ua rau lawv tus kheej paub. Feem ntau lawv muaj nyob tawm los ntawm kev huam yuaj, thaum lub sij hawm niaj hnub soj ntsuam los yog thaum lub sij hawm kev kho mob ntawm lwm yam gastrointestinal mob. Ib tug ntawm cov qog yog ib tug tubular adenoma ntawm cov nyuv. Externally nws pib ib tug me me nrog excrescence rau ntawm qhov chaw epithelium. Yog hais tias koj noj ib tug me me daim adenoma cov ntaub so ntswg (me) thiab xyuas nws nyob rau hauv ib tug tshuab kuaj kab mob, koj yuav saib tau lub mature hlwb ntawm txoj hnyuv. Raws li nrog rau tag nrho cov benign qog, lub histological qauv ntawm cov build-up repeats epithelial qauv. Txawm li cas los, tubular adenoma yog ib tug kab mob tiv thaiv uas feem ntau tsim colorectal cancer. Yog li ntawd, nws yog txaus ntshai rau cov kev kho mob ntawm tus neeg mob. Lwm lub npe rau qhov no benign qog ntawm txoj hnyuv - polypoid adenomas. Nws tshwm sim nyob rau hauv hais txog 5% ntawm cov pejxeem. Tus zaus ntawm tshwm sim ntawm lub adenoma tsis yog nyob ntawm seb muaj hnub nyoog thiab pw ua niam txiv ntawm tus neeg. Nyob rau hauv tej rooj plaub muaj ntau yam polyps. Nws yog ntseeg hais tias cov muaj ib tug tib tubular adenoma feem me me uas malignancy yog tsawg. Cuaj kaum, qhov kev kawm ntawv yog ib tug ua ntawm sau npe nyob rau hauv lub Oncology Center rau qhov kev saib xyuas.

Ua rau adenomas nyob rau hauv cov hnyuv

Zaum tau tseem tsis tau pom lub caij nyoog causative tau pab mus rau lub kev loj hlob ntawm plab hnyuv adenomas. Muaj ntau ntau theories ntawm benign qog. Feem ntau cov kws kho mob ntseeg tau hais tias lub leading lub luag hauj lwm ua si los ntawm lub ua ke ntawm ob peb yam tseem ceeb nyob rau hauv qhov tshwm sim ntawm tus kab mob no. Raws li nyob rau hauv no, qhia ib tug xov tooj ntawm ua ntawm tubular adenomas:

1. Caj predisposition. Caj nyob rau hauv cov ntaub ntawv ntawm plab hnyuv polyps yog ib qho tseem ceeb. Nyob rau hauv tej rooj plaub, tubular adenomas kuaj nyob rau hauv ob peb lub tsev neeg.
2. Qhov xwm ntawm lub hwj chim. Nws yog ntseeg hais tias cov neeg nyob rau hauv cov khoom noj uas yog muaj nyob rau hauv cov tsiaj muaj roj, muaj ib tug ib txwm mus rau lub tsos ntawm ob benign neoplasms thiab hnyuv mob cancer. Nyob rau hauv lem, kev pheej hmoo ntawm cov kev txawv txav yog txo los ntawm kev siv ntawm zaub, tshuaj ntsuab, cov zaub mov nplua nuj nyob rau hauv fiber.
3. Phem tsis tau.
4. Los ntawm lub cev los ntawm ntau yam tshuaj cov neeg ua hauj, ionizing tawg.
5. Stressful lub sijhawm.

Feem ntau cov feem ntau, tubular adenoma yog pom nyob rau hauv cov neeg laus. Vim lub fact tias qhov no pab pawg neeg ntawm cov neeg tsub kom kev pheej hmoo ntawm cov nyuv mob cancer, polyps no yuav tsum tau tshem tawm.

Hom ntawm tubular adenomas

Tubular adenoma yuav muaj ib tug txawv loj. Nws yog hom twg los ntawm ib tug ob peb millimeters rau 3.2 cm., Nyob rau hauv lub me me duab, cais "sessile" polyps, benign pedunculated. Raws li tubular adenomas txawv nyob rau hauv localization. Lawv yuav tsum tau nyob rau hauv lub plab, cov nyuv thiab qhov sigmoid nyuv. Nyob rau hauv lub xov tooj ntawm adenomas paim hluas thiab ntau yam polyps. Qhov loj tshaj tseem ceeb rau xaiv ib txoj kev ntawm kev kho mob thiab raug yog ib tug faib uas yog raws li nyob rau hauv lub histological qauv ntawm cov ntaub so ntswg neoplasms. Nyob rau hauv no tso tawm 3 hom ntawm plab hnyuv polyps:

1. Tubular benign adenoma. Tsom yuav pom hais tias qhov no hom ntawm polyp hlwb elongated los yog branching raj surrounded los ntawm connective cov ntaub so ntswg.
2. Tubular-villous adenoma - tsim nyob rau hauv tus ntawm cov nyom yam tseem ceeb nyob rau hauv lub qhaj ntawv ntawm kev kho mob. Lub rov tshwm sim ntawm no hom ntawm polyps kom kev pheej hmoo ntawm degeneration rau hauv cancer. Histological xeem qhia yuav ua li cas tubular hlwb thiab feem fibrosis.
3. Villous adenoma. Qhov no zoo ntawm plob tsis so tswj polyps yog ib qho obligate precancerous mob uas yog yeej ib txwm hloov mus rau hauv ib tug kab mob qog hlav. Thaum tshem xws kev kawm ntawv macropreparations tsa seaweed.

Nws yog ib nqi nco ntsoov tias, nyob rau hauv kev phem ntawm lub "txawm" tubular adenoma, nws yog yuav luag ib txwm hloov mus rau hauv ib tug villous polyp. Nyob rau nruab nrab, nws yuav siv sij hawm qhov chaw 4-5 xyoo tom qab nws foundations.

Cov soj ntsuam daim duab nyob rau hauv tubular adenoma ntawm txoj hnyuv

Thaum me me tubular adenoma muaj tsis muaj kev soj ntsuam ces. Qhov no yog vim lub fact tias kev kawm ntawv tsis cuam tshuam nrog rau tej lag luam los ntawm cov hnyuv thiab zaj quav. Yog hais tias polyp nce mus txog ob peb centimeters nyob rau hauv txoj kab uas hla (ntawm 2 los yog ntau tshaj), nws muaj peev xwm yuav xav tias nyob rau hauv kev soj ntsuam cov tsos mob. Ntawm lawv yog cov kev hloov xws li hnyuv tsis xis nyob, txawv txav paug, mob thaum lub sij hawm defecation. Cov tsos mob ntawm tubular adenoma:

1. Cem quav los yog raws plab.
2. Cov tsos ntawm cov ntshav thaum defecating. Qhov no yog vim lub fact tias faeces raug mob phab ntsa tubular adenoma.
3. Mob thaum lub sij hawm defecation.
4. Khaus nyob rau hauv lub qhov quav cheeb tsam.

Nco ntsoov hais tias cov tsos mob no tej zaum yuav qhia txog qhov uas tshwm sim ntawm cancer ntawm lub sigmoid los sis qhov quav. Yog li ntawd, txoj kev loj hlob ntawm ib tug uas zoo sib xws soj ntsuam daim duab no yog ib qho mob ceev yuav tsum tau nyob rau hauv lub proctologist.

Tubular nyuv adenoma nrog dysplasia: ib tug piav qhia ntawm

Mus benign nyob rau hauv cancer pib nrog ib tug gradual hloov nyob rau hauv lub cellular muaj pes tsawg leeg ntawm lub adenoma - dysplasia. Thaum tubular polyp ntawm tus txheej txheem yog tsis cai. Feem ntau cellular restructuring tshwm sim nyob rau hauv villous formations. Cuaj kaum, xws li ib tug tshaj plaws raws li ib tug tubular adenoma nrog dysplasia tshwm sim. Cov tshwm sim ntawm tsis paub qab hau hlwb feem ntau tshwm sim thaum lub polyp nyob rau hauv loj. Nyob rau hauv cov ntaub ntawv no, tubular adenoma transformed rau hauv tubulovillous villous kev kawm ntawv. Dysplasia yog tsis ib txwm indicative ntawm tus txheej txheem ntawm malignancy. Nws nyob ntawm cov neeg kawm ntawv ntawm kom loj hlob ntawm lub adenoma hlwb. Cuaj kaum, cov tsos ntawm undifferentiated hlwb txawm nyob rau hauv ib tug tsawg heev nqi tsub kom kev pheej hmoo ntawm plob tsis so tswj cancer hlav.

Degree ntawm dysplasia nyob rau hauv tubular adenomas

Faib 3 degrees ntawm dysplasia nyob rau hauv tubular plab hnyuv adenomas. Yuav ua li cas los mus hloov lub polyp hlwb tactics ntawm tus kws kho mob nyob. Tubular adenoma nrog dysplasia qib 1-2 muaj ib tug dej siab raug rau kev kho mob. Lub siab yuav qhov muaj tseeb ntawm degeneration rau hauv cancer cai nrog cim hloov nyob rau hauv lub cellular muaj pes tsawg leeg ntawm lub polyp. Ntsis dysplasia yog yus muaj los ntawm thooj ntawm cov basal txheej ntawm lub plab hnyuv epithelium. Hypochromic cell nucleus, tus xov tooj ntawm mitoses nce. mob loj tsawv dysplasia yog yus nyob rau hauv uas lub basal txheej ntawm cov epithelium yog qhov muag plooj, muaj ib tug qhia tau loj hlob ntawm lub hlwb nyob rau hauv lub sprout tsam. Tsis tas li ntawd, lub ntsiab lawv tus kheej yog cov sib txawv nyob rau hauv loj thiab zoo. Ntaus cim degree ntawm dysplasia yog ib tug davhlau ya nyob twg theem, ua raws li atypia. Hlwb uas txawv hyperchromic thiab polymorphism. Tus nab npawb ntawm hloov lub ntsiab yog los ntawm 0.5 mus rau 1% ntawm epithelial cov ntaub so ntswg.

Mob tubular plab hnyuv adenomas

Yog hais tias koj xav tias lub xub ntiag ntawm tubular adenomas ua endoscopic xeem. Cov no muaj xws mus xoos hnyuv laus thiab sigmoidoscopy. Qhov kev xaiv ntawm txoj kev nyob rau hauv lub qhov chaw ntawm tus polyp nyob rau hauv cov hnyuv. Tseem ceeb heev nyob rau hauv lub mob muab rau gistologicheskimu thiab cytology.

Kev kho mob ntawm tubular adenoma

Lub ntsiab txoj kev kho mob yog phais tshem tawm ntawm lub polyp. Nyob rau hauv tsawg zaus, tubular adenoma, cia li saib (rau me me). Nyob rau hauv cov ntaub ntawv no, tus neeg mob yuav tsum tau ua raws li ib tug noj haus thiab tshem tawm tsis tau phem. Feem ntau ua endoscopic polypectomy. Rau hauv loj heev dysplasia ua lub lag luam.

Kev tiv thaiv ntawm tubular adenomas

Twv seb lub kev loj hlob ntawm tubular adenoma tsis yooj yim sua. Cuaj kaum, los tiv thaiv ntsuas muaj xws li cov khoom noj kom (loj heev nyob rau hauv kev noj haus ntawm fiber, uas tsis muaj roj). Koj yuav tsum tau tshem tawm kev haus luam yeeb thiab haus dej haus cawv thaum uas tau txais burdened raws roj ntsha keeb kwm. Tom qab 60 xyoo ntawm pom zoo diagnostic xoos hnyuv laus.
