Ulwakhiwo olunzima luyiMibili yeMiscle
I-sphincter yesalathisi liqela leemisipha ekupheleni komxube ojikeleze i- anus kunye nokulawula ukukhululwa kwesigxina, ngaloo ndlela igcine i-continent. Kukho izihlunu ezimbini ze-sphincter: enye ingaphakathi kwaye enye ingaphandle. Imisipha yangaphandle isinceda ukugcina i-continent kwaye igcine isigxina kwi-rectum. Ukuba kukho ukulahleka kokulawulwa kwamasipha kwi-sphincter, ukungabikho komzimba kungenzeka.
Imisipha yangaphakathi ayikho phantsi kokulawula ngokuzithandela kodwa ilawulwa yinkqubo ye-nervous autonomic system. Imisipha yangaphandle inokulawulwa ngokuzithandela (idibene kwaye ingenelwanga). Imisipha yangaphakathi kunye yangaphandle isebenza kunye ukuphelisa isitoli emzimbeni ngokusebenzisa intshukumo yokuhamba.
Izifo Neemeko Ze-Anal Sphincter ezihlobene ne-IBD
I stenosis. I-stenosis ye-Anal isingavamile, kodwa inxulumene nesifo sesibindi sokugula (IBD) , kunye nesifo seCrohn ngaphezu kwe-ulcerative colitis. Kwi-stenosis ye-anal, i-sphincter engumngcipheko iyancipha, ukuya kwimeko apho kunzima ukuba neentshukumo. Ezinye iimpawu ziquka intlungu kunye nokuphuma kwamanzi. Le meko inokwenzeka kwakhona emva kokuhlinzwa (ngokukodwa ukukhishwa kwe-hemorrhoid) okanye ukudibaniswa nokusetyenziswa kakubi kwe-laxative okanye izifo.
Izifo ze-Crohn's. Ngenxa yokuba isifo sikaCrohn sinokuchaphazela nayiphi na inxalenye yendlela yokugaya emlonyeni ukuya kwi-anus, inokuchaphazela i-sphincter yesifo.
Kulinganiselwa ukuba ubuninzi be-1/3 yezigulane ezineesifo sikaCrohn ziza kuba neengxaki kwiindawo ze- perianal (inxalenye yomzimba malunga ne-anus). Abantu abanesifo sikaCrohn bangaba neengxaki kwi-anal sphincter, kwaye oku kungaquka:
- I-Abscess : I-abscess yindawo yokuqokelela emva kokusuleleka.
- Amafisithi : I-crack is a krazula kwi-canal yangasese engathi ibuhlungu kakhulu.
- I-Fistulae : I-fistula ngumzila ongavumelekanga phakathi kwamalungu amabini omzimba, njenge-anus kunye nesikhumba.
- Ukuvuvukala kwi-sphincter yesilwanyana
- Ulcers : Isilonda ngumngxuma okanye ubuhlungu kwimbali yesakhiwo, njengemisipha yomzimba.
AmaHemorrhoids (Iifayile). I-hemorrhoid iyimvumba ejikeleze i-anus evuvuka. Phantse nawuphi na umntu unokuhlakulela i-hemorrhoid, kwaye yingxaki ekhethekileyo kwabasetyhini abakhulelwe, abantu abanezifo zesibindi sokuvuvukala (IBD), nabani na ofumana isigxina esingapheliyo okanye isifo sohudo, kunye nabantu abangaphezu kweminyaka engama-50.
Ukungena. Abanye abantu abane-IBD bafumana ukungabikho, okanye ukukhululwa kwe-stool ngokuzibandakanya kwi-rectum. Oku kuya kwenzeka ngenxa yokuphazamiseka kwesi sifo okanye kungabangela umonakalo kwimisipha ye-sphincter yesi-anal. Oku kunokukhathazeka kakhulu kwizigulane, kwaye ukufumana ukuvuvukala kwi-IBD phantsi kolawulo kubalulekile ukukhusela ukuvela kwe-incontinence ye-fecal.
