ICarcinomaofrectum
Inkcazelo emfutshane:
I-Carcinomaofrectum ibizwa ngokuba ngumhlaza we-colorectal, lithumba eliqhelekileyo elibi kwi-gastrointestinal tract, isehlo sesibini kuphela kumhlaza wesisu kunye nommizo, yeyona ndawo ixhaphakileyo yomhlaza wesisu (malunga ne-60%).Uninzi lwezigulane zineminyaka engama-40 ubudala, kwaye malunga ne-15% ingaphantsi kweminyaka engama-30 ubudala.Indoda ixhaphake kakhulu, umlinganiselo wendoda ukuya kwesetyhini ngu-2-3: 1 ngokujongwa kweklinikhi, kufunyenwe ukuba inxalenye yomhlaza we-colorectal ivela kwi-polyps okanye i-schistosomiasis;ukuvuvukala okungapheliyo kwamathumbu, ezinye zinokubangela umhlaza;ukutya okunamafutha aphezulu kunye neprotheyini ephezulu kubangela ukwanda kwe-cholic acid secretion, le yokugqibela ichithwa kwi-polycyclic hydrocarbons engaxutywanga yi-intestinal anaerobes, enokubangela nomhlaza.
Izizathu ezibangela umhlaza wesisu
Ukudumba okungapheliyo kwamathumbu
Umhlaza we-adenoma yamathumbu
Ukutya kunye ne-carcinogens
Iindlela ezi-3 zokuvavanya umhlaza wesisu
1. Ukuhlolwa komnwe we-anal: eyona nto ilula luhlolo lwe-anal finger, oludla ngokusetyenziswa ekuxilongeni umhlaza we-rectal, oko kukuthi, ukusebenzisa iiglavu ze-aseptic ukufumanisa ukuba kukho umhlaza we-rectal ukusuka ekufakweni kwe-anal.
2. Ukuhlolwa kwemifanekiso: ukulinganisa okubandakanya i-CT kunye ne-MRI, ngoviwo lwe-CT kunye ne-MRI, ukufumanisa ukuba kukho ukuqina okungaqhelekanga okanye ukuphuculwa kodonga lwamathumbu, ukufumanisa ukuba kukho umhlaza we-colorectal.
3. I-Enteroscopy: i-enteroscopy iyona intuitive, kunye ne-enteroscopy, ngokufaka indawo ekugxilwe kuyo nge-enteroscopy, kunye ne-biopsy pathology ukumisela ukuxilongwa.
