Makhalidwe ovuta awa alidi Mitundu Iwiri
An anal sphincter ndi gulu la minofu kumapeto kwa rectum yomwe ili pafupi ndi anus ndi kuyendetsa kumasulidwa kwa mpando, potero kukhalabe continence. Pali mitsempha iŵiri ya sphincter: imodzi ili mkati ndipo imodzi ili kunja. Minofu yakunja imathandiza kukhalabe ndi chikhalire ndikukhala pansi pamtunda. Ngati pali kuperewera kwa mphamvu ya minofu mu sphincter, kudziletsa kumatha.
Minofu yamkati siyiyang'anila mwadzidzidzi koma imayang'aniridwa ndi kayendedwe ka mantha. Minofu yakunja ikhoza kuyendetsedwa mwaufulu (yosweka ndi yosasunthika). Minofu yamkati ndi yamkati imagwirira ntchito pamodzi kuthetsa mthunzi kuchokera pamtunda kupyolera pamtambo.
Matenda ndi Zinthu Zowopsa Kwa Sphincter Zogwirizana ndi IBD
Anal stenosis. Matenda otchedwa anal stenosis siwowamba, koma akhoza kugwirizana ndi matenda opatsirana a m'magazi (IBD) , komanso ku Crohn's disease kuposa ulcerative colitis. Mu anal stenosis, anal sphincter imakhala yopapatiza, mpaka kumakhala kovuta kukhala ndi chiwalo cha thupi. Zizindikiro zina zimaphatikizapo ululu ndi magazi. Matendawa amatha kuchitika pambuyo pa opaleshoni (makamaka kuchotsa magazi) kapena kugwiritsidwa ntchito ndi mankhwala osokoneza bongo kapena matenda.
Matenda a Anal Crohn. Chifukwa cha matenda a Crohn akhoza kuthandizira mbali iliyonse ya kapangidwe ka m'mimba kuchokera pakamwa kupita ku anus, imakhudza anal sphincter.
Zikuoneka kuti pafupifupi 1/3 mwa odwala omwe ali ndi matenda a Crohn adzakhala ndi mavuto m'dera la perianal (gawo la thupi pozungulira anus). Anthu omwe ali ndi matenda a Crohn amatha kukhala ndi mavuto mu anal sphincter, ndipo izi zikuphatikizapo:
- Amadzimadzi : Chosowa ndi malo omwe amatha kusonkhanitsa matendawa.
- Mafosholo : Kuwongolera kumabweretsa misozi yomwe imakhala yopweteka kwambiri.
- Fistulae : Fistula ndi njira yopanda malire pakati pa ziwalo ziwiri za thupi, monga anus ndi khungu.
- Kutupa mu anal sphincter
- Zilonda : Chilonda ndi dzenje kapena kupweteka m'makina a chigoba, monga minofu ya ana.
Mafupa (Mitsempha). Chifuwa chachikulu ndi mitsempha yoyandikana ndi anus yomwe imakhala kutupa. Pafupifupi aliyense angathe kukhala ndi magazi, ndipo ndi vuto lapadera kwa amayi apakati, anthu omwe ali ndi matenda opatsirana (IBD), aliyense amene amamva kudzimbidwa kapena kutsekula m'mimba, komanso anthu opitirira zaka 50.
Incontinence. Anthu ena omwe ali ndi IBD amakumana ndi chizoloŵezi chosadziletsa, kapena kumasulidwa mwachangu kwa sitima ya rectum. Izi zikhoza kuchitika chifukwa cha matendawa kapena zikhoza kuwonongeka kwa minofu ya anal sphincter. Izi zingakhale zovuta kwambiri kwa odwala, ndipo kupeza kutupa kwa IBD ndi kofunika kuti tipewe kupezeka kwa chiwerewere.
