I-Angiodysplasia yekholoni

I-Angiodysplasia yekholoni idumbile, imithambo yegazi ethe-ethe kwi-colon. Oku kunokubangela ukulahleka kwegazi kwiphecana lesisu (GI).

I-Angiodysplasia yekholoni ikakhulu inxulumene nokuguga kunye nokonakala kwemithambo yegazi. Kuqheleke kakhulu kubantu abadala abadala. Iphantse yabonwa kwicala lasekunene lekholoni.

Eyona nto inokwenzeka, ingxaki ikhula ngaphandle kwesiqhelo se-colon esenza ukuba imithambo yegazi kuloo ndawo ikhule. Xa oku kudumba kusiba nzima, indlela encinci ikhula phakathi komthambo omncinci kunye nomthambo. Oku kubizwa ngokuba yi-arteriovenous malformation. Ukopha kunokwenzeka kule ndawo eludongeni lwekholoni.

Rare, angiodysplasia ikholoni inxulumene nezinye izifo zemithambo yegazi. Enye yezi ngu-Osler-Weber-Rendu syndrome. Le meko ayihambelani nomhlaza. Ikwahlukile kune-diverticulosis, engunobangela oqhelekileyo wokuphuma kwegazi emathunjini kubantu abadala.

Iimpawu ziyahluka.

Abantu abadala banokuba neempawu ezinje:

• Ubuthathaka
• Ukudinwa
• Ukuphefumla kancinci ngenxa ye-anemia

Basenokungabonakali ngokuphuma kwegazi ngokuthe ngqo kwikholoni.

Abanye abantu banokuba nokuphuma kancinci okanye kakhulu ukopha apho igazi elibomvu okanye elimnyama livela kwi-rectum.

Akukho zintlungu zinxulunyaniswa ne-angiodysplasia.

Uvavanyo olunokwenziwa ukufumanisa le meko lubandakanya:

• I-Angiography (iluncedo kuphela ukuba kukho ukopha okusebenzayo kwikholoni)
• Gcwalisa ubalo lwegazi (CBC) ukujonga i-anemia
• Colonoscopy
• Uvavanyo lwe-Stool lwegazi (elifihliweyo) igazi (iziphumo zovavanyo ezilungileyo zibonisa ukopha kwikholoni)

Kubalulekile ukufumana unobangela wokopha kwikholoni kunye nokuba igazi lilahleka ngokukhawuleza kangakanani. Kuya kufuneka ungeniswe esibhedlele. Ulwelo lunokunikwa ngomthambo, kwaye kunokufuneka iimveliso zegazi.

Olunye unyango lunokufuneka xa umthombo wokopha ufumanekile. Kwiimeko ezininzi, ukopha kuyema ngokwakho ngaphandle konyango.

Ukuba unyango luyafuneka, lunokubandakanya:

• I-Angiografi ukunceda ukuvimba isikhephe segazi esophayo okanye ukuhambisa amayeza ukunceda ukuba imithambo yegazi iqiniswe ukunqanda ukopha.
• Ukutshisa (cauterizing) indawo yegazi egazini ngobushushu okanye i-laser kusetyenziswa ikholonoscope

Ngamanye amaxesha, kuphela kotyando. Unokufuna lonke icala lasekunene lekholoni (i-hemicolectomy esekunene) isuswe ukuba ukopha okunzima kuyaqhubeka, kwanasemva kokuba kuvavanywe olunye unyango. Amayeza (i-thalidomide kunye ne-estrogens) anokusetyenziselwa ukunceda ukulawula isifo kwabanye abantu.

Abantu abaphuma egazini abanxulumene nale meko ngaphandle kokuba bebe ne-colonoscopy, i-angiography, okanye utyando kusenokwenzeka ukuba babe nokopha ngakumbi kwixa elizayo.

Imbonakalo ihlala ilungile ukuba ukopha kuyalawulwa.

Iingxaki zinokubandakanya:

• Ukunqongophala kwegazi
• Ukufa okuphulukene nokuphulukana negazi
• Iziphumo ebezingalindelekanga zonyango
• Ukuphulukana kakhulu kwegazi kwiphecana le-GI

Tsalela umnxeba umboneleli wakho wezempilo ukuba kwenzeka ukuphuma kwegazi emqolo.

Akukho sithintelo saziwayo.
