Isifo esingokwemvelo esiyingozi ngumdlavuza wekoloni.

Izifo zekoloni - i-pathology, okuyinto edingekile ukuba ihlangabezane nodokotela. Ngokuvamile babhalisa ama- neoplasms amancane ekoloni, ngakho-ke izifo ezingokwemvelo ziyinkinga yekhulu lama-21. Izibalo zaseYurophu zibonisa ukuthi ngokuvamile iziphuzo eziyingozi zihlala endaweni yamaphaphu, indawo yesibili inomdlavuza wekoloni. Lesi sifo sivame ukurekhodwa kubantu abadala kuneminyaka engamashumi amahlanu. Ngo-2000, abantu abangaphezu kuka-130 000 bafa nge-colon carcinoma e-United States.

Kufanele kuthiwa umdlavuza wekoloni uvame kakhulu kubantu besifazane, kanti emadodeni kunomdlavuza we- rectum. Ucwaningo olwenziwe ngophenyo luye lwabonisa ukuthi izakhi zofuzo ze- colon carcinoma ziphansi kakhulu, kodwa lezi zincwadi zichaza amacala lapho umdlavuza wezinhlamvu ezibonakalayo ubonakaliswa ngezizukulwane eziningana, ngokuvamile eneminyaka engamashumi amane. Izici zokufaka izidakamizwa zibandakanya i-granulomatous colitis, i-ulcerative colitis, kanye ne-polyposis yomndeni.

Kutholakale ukuthi ukudla kweziguli ezitholakale "nomdlavuza omnyama" kwakucebile amaprotheni ezilwane, amafutha kanye nama-carbohydrate ahlanzekile futhi abampofu nge-cellulose. Izinto ze-carcinogenic zingabonakala kokubili emikhiqizweni yokudla, futhi zenziwe emzimbeni wemfihlo ye-bile namathumbu ngaphansi kwamandla ama-enzyme ebhaktheriya. Indlela ecacile yale nqubo ayisakaziwe.

Umdlavuza weColon ungasakazwa yi-metastasis enegazi elimnandi; I-Perineural; I-Metastasis ema-lymph nodes wesifunda; I-Metastasis ngaphakathi kwe-lumen ye-gut.

Umdlavuza weColon: izimpawu

I-Adenocarcinoma yamakoloni ikhula kancane kancane. Ukuze uqale ukukhombisa izibonakaliso zokuqala zesifo, kudingeke isikhathi esanele kakhulu. Ukuze uhlolwe ngokushesha ngesifo, udinga ukuhlolwa njalo ngezokwelapha. Yiqiniso, izimpawu zalesi sifo zixhomeke endaweni ye-neoplasm, uhlobo nokukala kwesilonda. Njengoba i-colon ekhuphuka ibonakala nge-lumen enkulu, udonga oluncane kanye nokuqukethwe kwamanzi, ukuvinjelwa kungenzeke ngesikhathi esiphezulu ekuthuthukiseni lesi sifo. Ngokujwayelekile i-carcinoma inesimo se-mushroom. Ama-sooplasms anjalo aphezulu kakhulu, ngezinye izikhathi angakwazi ngisho nokuzwa ngodonga lwesisu. Iziguli ezixilongwa "umdlavuza wekoloni" zingase zikhononde ngobuthakathaka obukhulu, obhekene ikakhulukazi ne-anemia enkulu. Umtholampilo ungabonakala njengobuhlungu be-colicky esiswini, okuhlobene nokuvimbela emathunjini. Ukukhipha igazi ngesikhathi sokuhlukunyezwa kungenye yezibonakaliso eziyinhloko zomdlavuza we-rectum

Ochwepheshe abaningi basikisela ukuqhuba ucwaningo lwendwangu yegazi elilindile. Izivivinyo ezengeziwe zenziwa ngomphumela omuhle. Uma kukhona ukusola komdlavuza, isifundo esikhethekile senziwa - i-fibrocolonoscopy. Imidwebo ye-barium enema iphumelela ekuhloleni umdlavuza we-colorectal. Ngaphambi kokuhlolwa, kufanele uhlanze ngokucophelela amathumbu. Ngenxa yalokhu, ama-laxatives kanye nama-enemas aphindaphindiwe anqunywe.

Ukwelashwa kusekelwe ekuthengiseni okuhlinzekwayo ezindaweni ezithintekile zamathumbu namathumba ezifunda. Ukukhethwa kokuhlinzwa kuncike ekungeni kwebanga le-tumor kusukela ku-anus nobukhulu bayo bonke. Ezimweni ezingaphezu kuka-70%, ukwelashwa okuhlinzekwayo kwenziwa. Ngezinye izikhathi, ukubhubhisa isisu, i-electrocoagulation inqunywe. Njengoba izindlela zokusiza zithi i-radiotherapy ne-chemotherapy. Ekupheleni kwekhulu lama-20, inhlanganisela esebenzisa i-5-fluoruracil ne-chloroethyl methylcyclohexylnitrosourea (i-methyl-CCNU) ibhekwa njengendlela yokwelapha ephumelela kakhulu ye-cyst colon. Kodwa-ke, ngokudlula ngokweqile kwe-methyl-CCNU, imiphumela emibi ibonakala: i-leukemia kanye nomonakalo wezinso ezinobuthi.
