I-lumen ingaphakathi kwamathumbu futhi kubalulekile ukuyigcina icacile
I-lumen ivule ngaphakathi kwesakhiwo somzimba we-tubular esizungezwe izicubu zomzimba ezibizwa ngokuthi i-membrane ye-epithelial. Izibonelo zezakhiwo zomzimba ezinesibindi zihlanganisa amathumbu amakhulu , amathumbu amancane , imithanjeni, nemithambo. Igama livela esiLatini esithi "lūmen," okusho ukuthi "ukukhanya." Lokhu mhlawumbe ngoba isibani singukuvula ngaphakathi kwebhubhisi, futhi ukukhanya kuzodlula phakathi kwebhubhisi.
Ubukhulu be-lumen emathunjini bungalinganiswa ukuze kutholakale ukuthi izindonga zamathumbu ziyakhula. Uma izindonga zamathumbu zinyathela futhi zenze ukuba lumen ibe yinkimbinkimbi, ingaholela ezinkingeni ezinjengezinsika.
I-Lumen yomathumbu
Emathunjini, i-lumen ivule ngaphakathi kwamathumbu futhi ihaqwe ezinye izingxenye zamathumbu: i-mucosa, i-submucosa, i-muscularis, ne-serosa.
Ukuze ukudla kudlule emathunjini, i-lumen kumele icace futhi ivuleke. Kubantu abanesifo sofuba (IBD) esivuvukalayo, isibani singase sithinteke. Ku-IBD, kunezikhathi zokuvuvukala ezithinta ungqimba lwe-mucosal lwamathumbu, okungabangela izilonda. Ukuvuvukala kungase kuphuluke ezindaweni, okubangela izicubu ezinzima. Umjikelezo ophindaphindiwe wokuvuvukala nokuphulukisa ungakha izicubu ezibomvu kuze kube yilapho liqinisa udonga lwesilonda.
Lapho i-Lumen Iba Nesibindi
Izicubu ze-Scar azihambisani nezimo njengezicubu ezivamile futhi ziziphatha ngendlela ehlukile. Uma kukhona izicubu ezibomvu emathunjini, i-lumen iyathinteka, futhi ingaba yanciphisa noma ivinjelwe. Ingxenye encane ye-lumen ibizwa ngokuthi yisimiso. Imfucuza ayikwazi ukudlula kahle i-lumen, engabangela ukuvimbela izifo noma ezinye izinkinga.
Izitshalo zivame ukuba zivame kakhulu esibhedlela sikaCrohn kunokuba zi-ulcerative colitis, noma kunjalo, zingenzeka kuzo zombili izinhlobo ze-IBD. Isizathu salokhu ukuthi isifo sikaCrohn singenzeka noma yikuphi emgodini wokugaya umzimba kusukela emlonyeni kuya ku-anus, futhi kungathinta izingqimba eziningana zodonga lwamathumbu. I-colcer ulcerative iyathinta nje amathumbu amakhulu kanye ne-rectum, futhi ukuvuvukala kuvamise ukufakwa ungqimba lwangaphakathi lwe-mucosal. Esigunjini sikaCrohn, izifo zivame ukuhlala emathunjini amancane, futhi ku-ulcerative colitis, izakhi zivame ukuthi zibe se-rectum.
Izimiso zingase zibe nzima kakhulu kubantu abane-IBD ngoba zivimbela ukudla ekuhambeni emathunjini. Ngezintambo ezincane kakhulu, ukudla kuqala ukubuyela emuva emathunjini. Lokhu kungaholela ekuvimbeleni isisu, futhi kungase kube nezimpawu zobuhlungu, ukuhlanza, uhudo, noma ukuqotshwa. Kwezinye izimo, izivimbelo zingelashwa esibhedlela nge-tube nasogastric (NG) nezinye izindlela, kodwa ezinye izici zihamba phambili ngokwanele ezidinga ukuhlinzwa. Ngaphandle kokuhlinzwa, izivimbelo zingase ziqhubeke ziqhubeka.
