Ubu bwoko bwa kanseri yo mu gifu biragoye kubimenya, witonde rero mugihe cya endoskopi!

Mu bumenyi buzwi cyane kuri kanseri yo mu gifu hakiri kare, hari ingingo zimwe na zimwe zita ku ndwara zidasanzwe zisaba kwitabwaho no kwiga.Imwe muri zo ni kanseri yo mu nda ya HP.Igitekerezo cya "ibibyimba bitanduye byanduye" ubu birakunzwe cyane.Hazabaho ibitekerezo bitandukanye kubibazo byizina.Iyi nyigisho ikubiyemo ahanini ishingiye ku kinyamakuru "Inda n'amara", kandi iryo zina rikoresha "kanseri yo mu nda ya HP".

Ubu bwoko bwibisebe bufite ibimenyetso biranga abantu bake, ingorane zo kumenyekana, ubumenyi bwimbitse, kandi inzira yoroshye ya MESDA-G ntabwo ikoreshwa.Kwiga ubu bumenyi bisaba guhangana ningorane.

1. Ubumenyi bwibanze bwa HP-mbi ya kanseri yo mu gifu

Amateka

Mu bihe byashize, abantu bemezaga ko nyirabayazana umwe mu kubaho no gutera kanseri yo mu gifu ari indwara ya HP, bityo rero uburyo bwa kanseri yo mu bwoko bwa kanseri ni HP - atrophy - metaplasia yo mu nda - ikibyimba gito - ikibyimba kinini - kanseri.Icyitegererezo cyakera cyamenyekanye cyane, cyemewe kandi cyizerwa.Ibibyimba bikurira hamwe hashingiwe kuri atrophy no mubikorwa bya HP, bityo kanseri ahanini ikura mumyanya yo munda ya atrophique hamwe na mucosa gastrica idasanzwe.

Nyuma, abaganga bamwe bavumbuye ko kanseri yo mu gifu ishobora kubaho nubwo nta HP yanduye.Nubwo igipimo cyanduye kiri hasi cyane, birashoboka rwose.Ubu bwoko bwa kanseri yo mu gifu yitwa kanseri yo mu nda ya HP.

Hamwe no gusobanukirwa buhoro buhoro ubu bwoko bwindwara, ubushakashatsi bwimbitse hamwe nincamake byatangiye, kandi amazina ahora ahinduka.Hari mu mwaka wa 2012 hari ingingo yiswe "Kanseri yo mu gifu nyuma ya Sterilisation", ingingo yo mu 2014 yiswe "Kanseri yo mu nda ya HP-mbi", n'ingingo yo muri 2020 yitwa "Ibibyimba bya Epitheliya bitanduye Hp".Guhindura izina byerekana ubushishozi bwimbitse kandi bwuzuye.

Ubwoko bwa Gland nuburyo bwo gukura

Hariho ubwoko bubiri bwibanze bwa glande na pyloric gland mu gifu:

Imvubura zifatika (glande oxyntique) zitangwa mu kigega, umubiri, inguni, nibindi byigifu.Ni umurongo umwe wigituba.Zigizwe na selile selile, selile selile, parietal selile na endocrine selile, buriwese ukora imirimo yawo.Muri byo, ingirabuzimafatizo zikomeye PGI na MUC6 zasohotse zari nziza, kandi selile parietal zasohoye aside hydrochloric nibintu byinjira;

Imvubura za pyloric ziherereye mu gice cya antrum gastric kandi zigizwe na selile selile na endocrine selile.Mucus selile ni MUC6 nziza, naho selile endocrine zirimo G, D selile na enterochromaffin.G selile isohora gastrine, D selile isohora somatostatine, na enterochromaffin selile isohora 5-HT.

Ingirabuzimafatizo zisanzwe zo mu nda hamwe na selile yibibyimba zisohora ubwoko butandukanye bwa poroteyine zo mu bwoko bwa mucus, zigabanyijemo poroteyine "gastric", "amara" na "ivanze".Imvugo yo mu gifu no mu mara yitwa fenotype kandi ntabwo ari ahantu hihariye h'igifu n'amara.

Hano hari selile enye za fenotipi yibibyimba byo munda: gastrica rwose, gastric-yiganje ivanze, amara-yiganjemo amara, kandi amara rwose.Ibibyimba bibaho bishingiye kuri metaplasia yo munda ahanini ni gastrointestinal ivanze na fenotype yibibyimba.Kanseri zitandukanye zerekana ahanini ubwoko bw'amara (MUC2 +), kandi kanseri ikwirakwiza yerekana ubwoko bwa gastric (MUC5AC +, MUC6 +).

Kumenya Hp mbi bisaba guhuza uburyo bwinshi bwo gutahura kugirango tumenye neza.Kanseri yo mu nda ya HP na kanseri yo mu gifu nyuma yo kubagwa ni ibintu bibiri bitandukanye.Ukeneye ibisobanuro birambuye kuri X-yerekana kanseri yo mu gifu ya HP-mbi, nyamuneka reba igice kijyanye n'ikinyamakuru "Inda n'amara".

2. Endoskopi igaragara ya HP-mbi ya kanseri yo mu gifu

Kwipimisha Endoscopique nibyo byibandwaho na kanseri yo mu nda ya HP.Harimo ahanini kanseri yo mu bwoko bwa kanseri yo mu gifu, kanseri yo mu bwoko bwa gland mucosal, kanseri yo mu gifu, adenoma gastric, raspberry foveolar epithelial tumor, signet ring selile carcinoma, nibindi. Iyi ngingo yibanze kuri endoskopi igaragara ya kanseri yibasira HP.
