I-Carcinomaofrectum
Inkcazo emfutshane:
I-Carcinomaofrectum ibizwa ngokuba ngumhlaza we-colorectal, sisisu esibi esixhaphakileyo kwindlela yamathumbu, ukwenzeka kwaso kukwindawo yesibini emva komhlaza wesisu nowe-esophagus, yeyona ndawo ixhaphakileyo yomhlaza we-colorectal (malunga nama-60%). Uninzi lwezigulane luneminyaka engaphezu kwama-40 ubudala, kwaye malunga ne-15% zingaphantsi kweminyaka engama-30 ubudala. Amadoda axhaphake kakhulu, umlinganiselo wamadoda kwabasetyhini yi-2-3:1 ngokwembono yeklinikhi, kufunyaniswe ukuba inxalenye yomhlaza we-colorectal ivela kwi-rectal polyps okanye kwi-schistosomiasis; ukudumba okungapheliyo kwamathumbu, amanye anokubangela umhlaza; ukutya okunamafutha amaninzi kunye neproteni ephezulu kubangela ukwanda kokukhutshwa kwe-cholic acid, le yokugqibela ibola ibe yi-unsaturated polycyclic hydrocarbons yi-intestinal anaerobes, enokubangela nomhlaza.
Izizathu ezibangela umhlaza we-colorectal
Ukudumba okungapheliyo kwamathumbu
Umhlaza we-intestinal adenoma
Ukutya kunye nezinto ezibangela umhlaza
Iindlela ezi-3 zokuvavanya umhlaza we-colorectal
1. Uvavanyo lweminwe yempundu: olulula luvavanyo lweminwe yempundu, oludla ngokusetyenziswa ekuxilongweni komhlaza wempundu, oko kukuthi, ukusebenzisa iiglavu ze-aseptic ukufumanisa ukuba ingaba kukho umhlaza wempundu osuka kwi-anal insertion.
2. Uvavanyo lwemifanekiso: ukuvavanya imifanekiso kuquka i-CT kunye ne-MRI, ngokusebenzisa uvavanyo lwe-CT kunye ne-MRI, ukufumanisa ukuba kukho ukutyeba okungaqhelekanga okanye ukuphuculwa kodonga lwamathumbu, ukufumanisa ukuba kukho umhlaza we-colorectal.
3. I-Enteroscopy: i-enteroscopy yeyona ilula kakhulu, ene-enteroscopy, ngokufaka indawo ekugxilwe kuyo nge-enteroscopy, uze emva koko ufake i-biopsy pathology ukuze kuchongwe ukuxilongwa.
