Yintoni i-pyloric sphincter?

Isisu sinento ebizwa ngokuba yi-pylorus, edibanisa isisu kunye ne-duodenum. I-duodenum licandelo lokuqala lamathumbu amancinci. Ngokudibeneyo, i-pylorus kunye ne-duodenum zidlala indima ebalulekileyo ekuncedeni ukuhambisa ukutya ngenkqubo yokwetyisa.

I-pyloric sphincter liqela lemisipha egudileyo elawula ukuhamba kokutya okwetyisiweyo kunye neencindi ezivela kwipylorus ukuya kwi-duodenum.

Ifumaneka phi?

I-pyloric sphincter ifumaneka apho i-pylorus idibana ne-duodenum.

Jonga umzobo odibeneyo we-3-D apha ngezantsi ukuze ufunde okungakumbi malunga ne-pyloric sphincter.

Yintoni umsebenzi wayo?

I-pyloric sphincter isebenza njengohlobo lwesango phakathi kwesisu kunye nethumbu elincinci. Ivumela imixholo yesisu ukuba ingene emathunjini amancinci. Ikwathintela ukutya okutyetyisiweyo kunye neencindi zokwetyisa ekungeniseni isisu kwakhona.

Amalungu asezantsi esivumelwano sesisu kumaza (abizwa ngokuba yi-peristalsis) anceda ekuqhekezeni ukutya ngoomatshini aze akudibanise neencindi zokwetyisa. Lo mxube wokutya kunye neencindi zokwetyisa ubizwa ngokuba yichyme. Amandla ezi contractions ayanda kwiindawo ezisezantsi zesisu. Ngomtsalane ngamnye, i-pyloric sphincter ivula kwaye ivumele intwana ye-chyme ukuba idlule kwi-duodenum.

Njengoko i-duodenum igcwalisa, ibeka uxinzelelo kwi-pyloric sphincter, ebangela ukuba ivale. I-duodenum isebenzisa i-peristalsis ukuhambisa i-chyme kuwo onke amathumbu amancinci. Emva kokuba i-duodenum ingenanto, uxinzelelo kwi-pyloric sphincter iyahamba, ivumela ukuba ivule kwakhona.

Zeziphi iimeko ezibandakanya oko?

Refilex yenyani

I-Bile reflux yenzeka xa i-bile ibuyela esiswini okanye kwisisu. Ibile lulwelo lokwetyisa olwenziwe esibindini oluhlala lufumaneka emathunjini amancinci. Xa i-pyloric sphincter ingasebenzi kakuhle, i-bile inokwenza indlela yayo yokugaya ukutya.

Iimpawu ze-bile reflux ziyafana kakhulu ne-asidi ye-asidi kwaye ibandakanya:

• intlungu ephezulu esiswini
• isilungulela
• isicaphucaphu
• ukugabha okuluhlaza okanye okumthubi
• ukukhohlela
• ukwehla kobunzima obungachazwanga

Uninzi lweziganeko ze-bile reflux ziphendula kakuhle kumayeza, anjenge-proton pump inhibitors, kunye notyando olusetyenziselwa ukunyanga i-acid reflux kunye ne-GERD.

I-pyloric stenosis

I-Pyloric stenosis yimeko kwiintsana ezithintela ukutya ekungeneni emathunjini amancinci. Yimeko engaqhelekanga ethanda ukuqhuba kwiintsapho. Phantse iipesenti ezili-15 zeentsana ezine-pyloric stenosis zinembali yosapho ye-pyloric stenosis.

I-pyloric stenosis ibandakanya ukuqina kwepylorus, okuthintela i-chyme ekubeni idlule kwi-pyloric sphincter.

Iimpawu ze-pyloric stenosis zibandakanya:

• ukugabha ngamandla emva kokondla
• indlala emva kokugabha
• ukuphelelwa ngamanzi emzimbeni
• ilindle elincinci okanye ukuqhina
• ukunciphisa umzimba okanye iingxaki zokufumana ubunzima
• Ukurhawuzelela okanye ukudumba esiswini emva kokondla
• ukucaphuka

I-pyloric stenosis ifuna utyando ukwenza ijelo elitsha elivumela i-chyme ukuba idlule iye emathunjini amancinci.

Gastroparesis

I-Gastroparesis ithintela isisu ekupheliseni ngokufanelekileyo. Kubantu abanale meko, i-wave-like contractions ezihambisa i-chyme ngenkqubo yokwetyisa zibuthathaka.

Iimpawu zegastroparesis zibandakanya:

• isicaphucaphu
• ukugabha, ngakumbi ukutya okungekacetyiswa emva kokutya
• iintlungu esiswini okanye ukudumba
• i-asidi ye-asidi
• imvakalelo yokugcwala emva kokutya izixa ezincinci
• ukuhla kweswekile yegazi
• ukungathandi ukutya
• ukuhla ukusinda

Ukongeza, amayeza athile, anje ngokuthomalalisa iintlungu opioid, anokwenza iimpawu zibembi.

Kukho iindlela ezininzi zonyango lwe-gastroparesis, kuxhomekeke kubukhali:

• utshintsho kwindlela otya ngayo, njengokutya ukutya okuncinci ngosuku okanye ukutya ukutya okuthambileyo
• ukulawula amanqanaba eglucose egazini, nokuba ngamayeza okanye utshintsho kwindlela yokuphila
• ityhubhu yokondla okanye ukufakwa kwezondlo ngaphakathi ukuze kuqinisekiswe ukuba umzimba ufumana iikhalori ezaneleyo kunye nezondlo

Umgca wezantsi

I-pyloric sphincter sisangqa semisipha egudileyo edibanisa isisu kunye namathumbu amancinci. Iyavula kwaye ivale ukulawula ukuhanjiswa kokutya okwetyisiweyo kunye neencindi zesisu ukusuka kwi-pylorus ukuya kwi-duodenum. Ngamanye amaxesha, i-pyloric sphincter ibuthathaka okanye ayisebenzi ngokufanelekileyo, ekhokelela kwiingxaki zokugaya ukutya, kubandakanya i-bile reflux kunye ne-gastroparesis.
