Yini i-pyloric sphincter?

Isisu siqukethe into ebizwa nge-pylorus, exhuma isisu ne-duodenum. I-duodenum yingxenye yokuqala yamathumbu amancane. Ngokubambisana, i-pylorus ne-duodenum zidlala indima ebalulekile ekusizeni ukuhambisa ukudla ngohlelo lokugaya ukudla.

I-pyloric sphincter ibhande lemisipha ebushelelezi elawula ukuhamba kokudla okugayiwe kancane kanye namajusi kusuka ku-pylorus kuya ku-duodenum.

Itholakala kuphi?

I-pyloric sphincter itholakala lapho i-pylorus ihlangana khona ne-duodenum.

Hlola umdwebo we-3-D osebenzisanayo ngezansi ukuze ufunde kabanzi nge-pyloric sphincter.

Uyini umsebenzi wayo?

I-pyloric sphincter isebenza njengohlobo lwesango phakathi kwesisu namathumbu amancane. Ivumela okuqukethwe yisisu ukuthi kudlulele emathunjini amancane. Iphinde ivimbele ukudla okugayiwe kancane kanye namajusi wokugaya ukudla angaphinde angene esiswini.

Izingxenye ezingezansi zesisu zithola amagagasi (abizwa ngokuthi yi-peristalsis) asiza ekudilizeni ukudla ngomshini bese akuxube namanzi wokugaya ukudla. Le ngxube yeziphuzo zokudla nezokugaya ukudla ibizwa nge-chyme. Amandla alezi zingqinamba akhula ezingxenyeni ezingezansi zesisu. Ngegagasi ngalinye, i-pyloric sphincter ivula futhi ivumele i-chyme encane ukuthi idlule ku-duodenum.

Njengoba i-duodenum igcwalisa, ibeka ingcindezi kwi-pyloric sphincter, ibangele ukuthi ivalwe. I-duodenum bese isebenzisa i-peristalsis ukuhambisa i-chyme kuwo wonke amathumbu amancane. Lapho i-duodenum ingasenalutho, ingcindezi ku-pyloric sphincter iyahamba, ivumele ukuthi ivule futhi.

Yimiphi imibandela ehilela lokhu?

I-Reflux yenyoni

I-Bile reflux yenzeka lapho i-bile ibuyela esiswini noma esophagus. IBile iwuketshezi lokugaya ukudla olwenziwe esibindini esivame ukutholakala emathunjini amancane. Lapho i-pyloric sphincter ingasebenzi kahle, i-bile ingenza indlela yayo inyuse umgudu wokugaya ukudla.

Izimpawu ze-bile reflux ziyefana kakhulu nalezo ze-acid reflux futhi zifaka:

• ubuhlungu besisu
• isilungulela
• isicanucanu
• uhlanza oluhlaza noma oluphuzi
• ukukhwehlela
• ukuncipha kwesisindo okungaqondakali

Izimo eziningi ze-bile reflux ziphendula kahle emithini, efana ne-proton pump inhibitors, nokuhlinzwa okusetshenziselwa ukwelapha i-acid reflux ne-GERD.

I-pyloric stenosis

I-pyloric stenosis yisimo ezinganeni ezivimba ukudla ukungena emathunjini amancane. Kuyisimo esingajwayelekile esivame ukusebenza emindenini. Cishe i-15% yezinsana ezine-pyloric stenosis zinomlando womndeni we-pyloric stenosis.

I-pyloric stenosis ifaka ukuqina kwe-pylorus, okuvimbela i-chyme ukuthi idlule kwi-pyloric sphincter.

Izimpawu ze-pyloric stenosis zifaka:

• ukuhlanza okunamandla ngemuva kokudla
• indlala ngemuva kokuhlanza
• ukoma komzimba
• indle encane noma ukuqunjelwa
• ukwehlisa isisindo noma izinkinga zokuthola isisindo
• ukucindezela noma ukuqhuma esiswini ngemuva kokudla
• ukucasuka

I-pyloric stenosis idinga ukuhlinzwa ukudala isiteshi esisha esivumela i-chyme ukuthi idlule emathunjini amancane.

I-Gastroparesis

I-Gastroparesis ivimbela isisu ekuchithekeni kahle. Kubantu abanalesi simo, izingqinamba ezinjengamagagasi ezihambisa i-chyme ngohlelo lokugaya ukudla zibuthakathaka.

Izimpawu ze-gastroparesis zifaka:

• isicanucanu
• ukuhlanza, ikakhulukazi kokudla okungadliwe ngemuva kokudla
• ubuhlungu besisu noma ukuqunjelwa
• i-asidi ye-asidi
• ukuzwa kokugcwala ngemuva kokudla amanani amancane
• ukushintshashintsha kweshukela egazini
• ukungathandi ukudla
• ukuncipha komzimba

Ngaphezu kwalokho, imishanguzo ethile, enjenge-opioid pain relievers, ingenza izimpawu zibe zimbi kakhulu.

Kunezinketho zokwelashwa eziningana ze-gastroparesis, ngokuya ngobukhulu:

• izinguquko zokudla, njengokudla ukudla okuncane okuncane ngosuku noma ukudla ukudla okuthambile
• ukulawula amazinga kashukela egazini, kungaba ngemithi noma ngoshintsho lwendlela yokuphila
• ukondla ngamashubhu noma izakhi zomzimba ezifakwe emithanjeni ukuqinisekisa ukuthi umzimba uthola amakhalori nezakhi zomzimba ezanele

Okubalulekile

I-pyloric sphincter iyindandatho yemisipha ebushelelezi exhuma isisu namathumbu amancane. Iyavula futhi ivale ukulawula ukudluliswa kokudla okugayiwe ngokwengxenye neziphuzo zesisu ezisuka kwi-pylorus ziye e-duodenum. Kwesinye isikhathi, i-pyloric sphincter ibuthakathaka noma ayisebenzi kahle, okuholela ezinkingeni zokugaya ukudla, kufaka phakathi i-bile reflux ne-gastroparesis.
