Umdlavuza weColon


Uyini umdlavuza kapopopo?

Umdlavuza wekoloni igama elivamile elisetshenziselwa ukuchaza iqembu lezimila eziyingozi (ezinomdlavuza) ezivela kumaseli avame ukutholakala kukholoni. Isimila esiyingozi sakhiwe amangqamuzana angavamile anamandla okwenza bahlasele izicubu ezizungezile futhi zisakaze kwezinye izingxenye zomzimba.

Uhlobo oluvame kakhulu lomdlavuza wamathumbu lubizwa i-adenocarcinoma futhi iqala kusukela kumaseli ngokuvamile atholakala ku acorns ezimboza ingaphakathi lekholoni. Izinhlobo ezingaphansi ezingavamile ze-adenocarcinoma zihlanganisa i-adenocarcinoma ye-mucinous, i-signet-ring cell adenocarcinoma, i-medullary adenocarcinoma, i-serrated adenocarcinoma, i-micropapillary adenocarcinoma, i-adenocarcinoma efana ne-adenoma, ne-adenosquamous adenocarcinoma.

Uqala kanjani umdlavuza wekoloni?

Izinhlobo eziningi zomdlavuza kapopopo ziqala ekukhuleni okuncane ngaphakathi kwekholoni okuthiwa a i-polyp. Odokotela benza ukuhlolwa okubizwa ngokuthi i-colonoscopy ukuze babone futhi bakhiphe ama-polyps kukholoni ngaphambi kokuba abe umdlavuza. Izinhlobo zama-polyps ezingashintsha zibe umdlavuza ngokuhamba kwesikhathi zihlanganisa i-adenoma ye-tubular, i-adenoma ye-tubulovillous, i-adenoma embi, Futhi isilonda se-sessile serrated (ebizwa nangokuthii-adenoma ye-serrated). A i-hyperplastic polyp wuhlobo oluvame kakhulu lwe-polyp olungeke luguquke lube umdlavuza ngokuhamba kwesikhathi.

Utholwa kanjani umdlavuza wekoloni?

Ezigulini eziningi, umdlavuza wekoloni utholwa ngemva kokukhishwa kwesampula yethishu encane ngendlela ebizwa ngokuthi a i-biopsy noma i-polypectomy (uma yenzelwe ukususa i-polyp). Isampula lethishu libe selithunyelwa kudokotela wezifo osihlola ngesibonakhulu. Ngokuhlola izicubu ngaphansi kwesibonakhulu, udokotela wezifo angakwazi ukunquma uhlobo lomdlavuza wekoloni futhi angakwazi uku-oda noma yikuphi ukuhlolwa okwengeziwe okungasiza ekuqondiseni ukunakekelwa kwakho. Kuye ngohlobo lwesimila, enye inqubo ingase yenziwe ukuze kukhishwe sonke isimila ngendlela ebizwa ngokuthi a ukukhishwa kabusha. Izindawo ezinama-lymph ku-axilla (i-armpit) ingase ikhishwe ngesikhathi esifanayo ukuze kubhekwe noma yimaphi amaseli wesimila asabalele ku-lymph node.
