Ngexesha lokuhlolwa kwezonyango, ezinye iimvavanyo zabucala nezibonakala ziyingxaki zihlala zitsitywa, njengovavanyo lwegazi lobugqi.(FOBT).

Abantu abaninzi, xa bejongene nesikhongozeli kunye nentonga yesampulu yokuqokelela isitulo, bayathanda ukuyiphepha ngenxa "yokoyika ukungcola," "intloni," okanye "becinga ukuba kuxakeke." Nangona kunjalo, olu vavanyo luhlala lujongelwa phantsi "luvavanyo lwesitulo" lunokusindisa ubomi ngamaxesha anzima.

UNksz Wu, oneminyaka engama-59, utyelele ikliniki emva kokuva iveki yelindle elinegazi. Akazange alindele ukuba uvavanyo awayelutsibe iminyaka emithathu elandelelanayo, okokuqala ngqa, luza kubonisa ukuba une-HIV ngendlela ye-immunochemical, ekhokelela ekufunyanisweni kwangaphambili komhlaza we-rectal nge-colonoscopy. Emva kokususwa ngotyando, izinga lokusinda kwakhe kwiminyaka emihlanu liye lagqitha kuma-90%.

Ngokwahlukileyo koko, ummelwane wakhe, uMnu. Zhang, owayesele elutyeshele ixesha elide olu “khetho lunzima” kwifomu yakhe yokujonga unyango, wafunyaniswa ukuba unomhlaza we-colorectal ophucukileyo kuphela emva kokuva iintlungu zesisu kunye nendle enegazi, enciphisa izinga lokusinda kwakhe libe ngaphantsi kwe-10%.

Kutheni ungatsibi iuvavanyo lwegazi lobugqi?
Ixabiso elingundoqo leFOBTilele ekubhaqeni (micro-bleeding) kwindlela yokwetyisa. Xa kukho ukopha okuncinci (imihla ngemihla kuphela i-2-5ml), iiseli ezibomvu zegazi sele zigaywe kwaye zaphulwa, okwenza isitulo sibonakale siqhelekileyo ngaphandle kwegazi elibonakalayo kwaye singabonakali phantsi kwe-microscope. Nangona kunjalo, ukutshatyalaliswa kweeseli ezibomvu zegazi kukhulula i-hemoglobin, enokuthi ibonwe ngeendlela zekhemikhali okanye ze-immunochemical.

Oku kopha kancinci kunokuba luphawu lwakwangoko lwethumba lokutya (ezifana nomhlaza wesisu okanye umhlaza wesisu). Uphononongo lufumanise ukuba i-87% yezigulana ezinethumba lokugaya ukutya zinovavanyo lwegazi lwe-fecal occult positive. Kuba ukopha kwe-tumor kuphakathi, uvavanyo olunye lunokuphosa ukuxilongwa. Nangona kunjalo, ukuhlolwa rhoqo ngonyaka kunokuphucula kakhulu izinga lokubona izilonda. Ngokwezibalo ezingaphelelanga, ukuhlolwa kwe-FOBT okungaguqukiyo kunokunciphisa ukufa komhlaza we-colorectal nge-10% -30%. Okwangoku, izikhokelo ezininzi zokuthintela zincoma kakhulu njengento yokuhlola.

Uvavanyo oluDityanisiweyo longeza ukuchaneka

Uphando lubonisa ukuba ngaxeshanye uvavanyo lwe-hemoglobin (Hb) kunye itransferrin (Tf)inokugubungela iimeko zokopha ngakumbi kwaye iphucule ukuchaneka kokubonwa.

Transferrinizinze ngakumbi kwisitulo kune-hemoglobin, ngoko ke ukuvavanywa kokubini kunokunciphisa izinto ezingalunganga ezibangelwa kukunyamalala kwe-antigenicity ye-hemoglobin. Uvavanyo oludityanisiweyo lubonelela ngezi nzuzo zilandelayo: ukuchaneka okuqinileyo, ubuntununtunu obuphezulu, ukusebenza okulula, ukugqitywa kwenyathelo elinye, kunye nokutolika kweziphumo ngokulula.

Ngoobani Abafanele Benziwe Olu Vavanyo?

Abantu abaneminyaka engama-40 nangaphezulu kufuneka baye kuvavanyo lwegazi lobugqi obulindle ubuncinane kanye ngonyaka.

Ukuba unayo nayiphi na kwezi meko zilandelayo, kuya kufuneka wandise ukuphindaphindwa kovavanyo lwegazi lobugqi:

A. Imbali yosapho yomhlaza wesisu okanye umhlaza.

B. Imbali yomhlaza womhlaza, i-colorectal adenoma, okanye i-post-polypectomy.

C. Imbali ye-colitis.

D. Imbali ye-gynecological malignancies nge-radiotherapy ye-pelvic.

E. Ngaphezu kweminyaka eyi-10 emva kwe-cholecystectomy.

F. I-anemia eyingozi ephindaphindiweyo.

G. Chronic atrophic gastritis, izilonda zesisu, iipolyps zesisu, okanye imbali yotyando lwesisu.

H. Amadoda ama-20-25 kg atyebe kakhulu okanye atshayayo.

I. Ukusuleleka kwe-Helicobacter pylori: kwandisa umngcipheko womhlaza wesisu ngama-2-3 amaxesha.
