Iyini i-polyp evuthayo esiswini?

I-polyp evuvukalayo iwukukhula okungenawo umdlavuza okuvela esicutshini esigudle ingaphakathi lesisu. Elinye igama lalokhu kukhula yi-a i-hyperplastic polyp.

Yini ebangela i-polyp evuvukalayo?

Ama-polyps amaningi avuvukalayo esiswini ahlotshaniswa nesimo esibizwa ngokuthi i-gastritis engapheli noma isikhathi eside ukuvuvukala esiswini. Izimbangela ezivame kakhulu ze-gastritis engapheli ukutheleleka kwesisu nge Helicobacter pylori, i-bile reflux, kanye ne-autoimmune gastritis.

Ingabe i-polyp evuvukalayo ingaphenduka umdlavuza?

Akuvamile ukuthi umdlavuza uthuthuke ku-polyp evuvukalayo.

Izazi ze-pathologist zikwenza kanjani lokhu kuxilonga?

Lokhu kuhlonza ngokuvamile kwenziwa ngemva kokuba ingxenye noma yonke i-polyp isusiwe phakathi nenqubo ebizwa ngokuthi i-endoscopy. Le nqubo ihilela ukusebenzisa ikhamera exhunywe eshubhuni elide ukuze ubone ingaphakathi lesisu. Isicubu esisusiwe sibe sesithunyelwa kudokotela wezifo ukuze sihlolwe ngesibonakhulu.

Ibukeka kanjani i-polyp evuthayo ngaphansi kwe-microscope?

Lapho kuhlolwa ngaphansi kwe-microscope, ama-polyp avuvukalayo abonisa inani elikhulayo lamaseli e-foveolar enza i-epithelium ubukeke ungahlelekile. Izikhala ezinkulu ezivulekile noma ezinwetshiwe zingase zithuthuke. Izicubu ezixhumeneyo noma i-stroma ezungeze amaseli e-foveolar ngokuvamile abonisa izimpawu ze ukuvuvukala okuhlanganisa nenani elandiwe amangqamuzana okuvuvukala njenge amaseli e-plasma, i-lymphocytesnama-neutrophils.

Ngoba ama-polyps avuthayo angabangelwa ukutheleleka kwesisu nge-bacteria ebizwa ngokuthi Helicobacter pylori, udokotela wakho wezifo angase enze izivivinyo ezifana amabala akhethekile or i-immunohistochemistry ukubheka amagciwane kusampula yethishu. Kokubili lokhu kuhlola kwenza kube lula ukubona amagciwane amancane kakhulu futhi okunzima ukuwabona ku-a i-hematoxylin ne-eosin-stained (H&E) isilayidi.
