I-Angiodysplasia yekoloni

I-Angiodysplasia yekoloni iyavuvukala, imithambo yegazi entekenteke koloni. Lokhu kungaholela ekulahlekelweni kwegazi okuvela kumgudu wamathumbu (GI).

I-Angiodysplasia yekoloni ihlobene kakhulu nokuguga nokonakala kwemithambo yegazi. Kuvame kakhulu kubantu abadala asebekhulile. Kucishe kubonakale ngasohlangothini lwesokunene lekholoni.

Kungenzeka, inkinga ivela ezimpahleni ezijwayelekile zekholoni ezenza ukuthi imithambo yegazi endaweni ikhulise. Lapho lokhu kuvuvukala kuba nzima, indlela encane ikhula phakathi komthambo omncane nomthambo. Lokhu kubizwa ngokuthi yi-arteriovenous malformation. Ukopha kungavela kule ndawo odongeni lwamakholoni.

Akuvamile, i-angiodysplasia yekoloni ihlobene nezinye izifo zemithambo yegazi. Enye yazo i-Osler-Weber-Rendu syndrome. Isimo asihlobene nomdlavuza. Kubuye kwehluke kune-diverticulosis, okuyimbangela ejwayelekile kakhulu yokopha kwamathumbu kubantu abadala asebekhulile.

Izimpawu ziyahlukahluka.

Abantu abadala bangaba nezimpawu ezinjengalezi:

• Ubuthakathaka
• Ukukhathala
• Ukuphefumula okuncane ngenxa yokushoda kwegazi

Kungenzeka bangabi negazi elibonakalayo ngqo kusuka kukholoni.

Abanye abantu bangaba neziqubu zokopha okuncane noma okunzima lapho igazi elibomvu noma elimnyama livela ku-rectum.

Abukho ubuhlungu obuhambisana ne-angiodysplasia.

Ukuhlolwa okungenziwa ukuthola lesi simo kufaka:

• I-Angiography (ilusizo kuphela uma kukhona ukopha okusebenzayo kukholoni)
• Qedela ukubalwa kwegazi (CBC) ukuhlola i-anemia
• Colonoscopy
• Ukuhlolwa kwesitokisi kwegazi lokufihla (okufihliwe) (umphumela omuhle wokuhlolwa uphakamisa ukopha kukholoni)

Kubalulekile ukuthola imbangela yokopha kukholoni nokuthi igazi lilahleka ngokushesha kangakanani. Ungadinga ukuthi ungeniswe esibhedlela. Uketshezi kunganikezwa ngomthambo, futhi kungadingeka imikhiqizo yegazi.

Olunye ukwelashwa kungadingeka lapho umthombo wokopha utholakele. Ezimweni eziningi, ukuphuma kwegazi kuyazimela ngaphandle kokwelashwa.

Uma kudingeka ukwelashwa, kungabandakanya:

• I-Angiography ukusiza ukuvimba umthambo wegazi opha noma ukuletha umuthi wokusiza ukuthi imithambo yegazi iqinise ukumisa ukopha
• Ukushisa (cauterizing) isiza segazi ngokushisa noma nge-laser usebenzisa i-colonoscope

Kwezinye izimo, ukuhlinzwa kuyindlela kuphela. Ungadinga lonke uhlangothi lwangakwesokudla lwekholoni (hemicolectomy yangakwesokudla) uma kukhishwa ukopha okunzima kuqhubeka, noma sekuzanywe ezinye izindlela zokwelapha. Imithi (i-thalidomide ne-estrogens) ingasetshenziswa ukusiza ukulawula lesi sifo kwabanye abantu.

Abantu abaphuma igazi abahlobene nalesi simo yize babe ne-colonoscopy, i-angiography, noma ukuhlinzwa kungenzeka baphume kakhulu igazi ngokuzayo.

Umbono uhlala umuhle uma ukuphuma kwegazi kulawulwa.

Izinkinga zingafaka:

• Ukushoda kwegazi
• Ukufa ngokulahleka kwegazi ngokweqile
• Imiphumela emibi yokwelashwa
• Ukulahleka okukhulu kwegazi okuvela epheshaneni le-GI

Shayela umhlinzeki wakho wezempilo uma kwenzeka ukuphuma kwegazi.

Akukho ukuvimbela okwaziwayo.
