Intshayelelo yeMveliso

I-Intestinal stent sisixhobo sonyango esisetyenziselwa ukunyanga ukucutha kunye nokuphazamiseka kwendlela yokugaya. Ngokuqhelekileyo zenziwe ngesinyithi okanye izinto ze-alloy, kunye nesakhiwo sothungelwano esinokutyhila kunye nokuxhasa iindawo ezincinci.

Umsebenzi we-stents wamathumbu kukuvula amathumbu amancinci kunye nokugcina i-intestinal patency. Xa i-digestive tract iyancipha okanye ivalekile, ukuhamba kokutya kunye nolwelo kuthintelwe, okukhokelela kwiingxaki zokugaya kunye nokungahambi kakuhle. Ukufakelwa kwamathumbu e-intestinal stents kunokubuyisela i-intestinal patency yesiqhelo, ukuphucula iimpawu zezigulane kunye nomgangatho wobomi.

I-stents zamathumbu zingahlelwa kwiintlobo ezahlukeneyo ngokusekelwe kwindawo kunye nomsebenzi wabo. Ezinye iintlobo eziqhelekileyo ze-stents zamathumbu ziquka:

I-Dynamic intestinal stent: Esi stent sinokuhlehla ngokuguquguqukayo ukuqhelanisa notshintsho emathunjini kunye nokugcina i-patency yamathumbu. Ngokuqhelekileyo zisetyenziselwa ukusetyenziswa kwexesha elide ukunciphisa imfuno yokusebenza kwakhona.

I-stent yamathumbu ezandisayo: Esi stent sisebenzisa izixhobo ezikhethekileyo ezinokuzandisa kwaye zandise umgudu omncinci wokwetyisa emzimbeni.

I-stent yamathumbu ekhutshwayo: Le stent inokususwa lula ngoogqirha xa ifuneka kwaye isetyenziselwa unyango lwexesha elifutshane.

Inkqubo yokufakelwa kwamathumbu kusetyenziswa iintendelezo zamathumbu idla ngokuba yinto encinci yokuhlasela kwaye inokwenziwa ngeendlela ezinje nge-endoscopy. Emva kokuhlinzwa, izigulane zinokudinga ukuhlolwa rhoqo ukuze kuqinisekiswe umsebenzi kunye nendawo ye-stent.

Nceda uqaphele ukuba ukusetyenziswa kwamathumbu emathunjini kufuna ukuvavanya ugqirha ngaphambi kokuba wenze isigqibo, kwaye isicwangciso sonyango esifanelekileyo kunye nohlobo lwe-stent luya kumiselwa ngokusekelwe kwimeko ethile kunye neemfuno zesigulane. Ukuba uneminye imibuzo okanye ufuna ulwazi oluthe kratya malunga nemveliso ethile, nceda udibane nogqirha okanye iziko lonyango lobungcali.

ImvelisoIimbonakalo

I-Intestinal stent sisixhobo sonyango esisetyenziselwa ukunyanga i-intestinal stenosis okanye ukuvaleka. Ezi zilandelayo zezinye iimpawu kunye neenzuzo ze-stents zamathumbu, ezivumela abatyeleli ukuba babe nokuqonda okungaphezulu kolwazi lwemveliso:

Inkxaso eyomeleleyo: I-intestinal stent yenziwe ngezinto eziguquguqukayo kunye nezizinzileyo ze-alloy, ezinenkxaso eyaneleyo kwaye inokuphucula ngokufanelekileyo i-intestinal patency. Uyilo olukhethekileyo lwe-bracket luvumela ukuba luhambelane nesimo samathumbu, ukuqinisekisa ukuzinza kunye nokufaneleka.

Ukuthembeka kwexesha elide: Izinto eziphathekayo kunye noyilo lwe-intestinal stent lubonelela ngokugqwesileyo okugqwesileyo kunye nokuzinza kwexesha elide. Iyakwazi ukuhlala emathunjini ixesha elide, incede ukubuyisela umsebenzi wamathumbu, kunye nokunciphisa iimpawu kunye nokukhathazeka.

Utyando olungangeneleli: Xa kuthelekiswa neendlela zotyando zesintu, ukufakela amathumbu amathumbu kudla ngokuba lukhetho lonyango olungaphazamisiyo. Ifakwe nge-endoscopy okanye indlela ye-percutaneous, ukuphepha umngcipheko kunye nexesha lokubuyisela utyando oluvulekileyo.

Ukulungiselela wena: I-stent yamathumbu ingenziwa ngokwezifiso ngokwemeko ethile yesigulane. Izigulana ezahlukeneyo zinokufuna ubukhulu obuhlukeneyo kunye nemilo yee-stents ukulungelelanisa kwindawo ye-intestinal stenosis.

Iziphumo zexesha elifutshane kunye nezexesha elide: Ukufakelwa kwamathumbu emathunjini kunokuphucula ngokukhawuleza i-intestinal patency kunye nokunciphisa iimpawu. Kwezinye izigulana, ukusebenza kwe-stents kunokuhlala iminyaka emininzi, ukunciphisa imfuno yonyango rhoqo.

Nangona i-stents yamathumbu ineenzuzo ezininzi, izigulane kufuneka zidibanise kwaye zixoxe noogqirha bazo ngokubanzi xa bekhetha iindlela zonyango. Imeko yesigulane ngasinye iyahluka, kwaye oogqirha baya kugqiba ukuba ngaba kufanelekile ukufakela i-stents yamathumbu esekelwe kwiimfuno zomntu ngamnye kunye neenjongo zonyango.

Isicelo

Ukusetyenziswa kwe-stents yamathumbu kusetyenziswa ikakhulu ukunyanga ezi meko zilandelayo:

I-stenosis yamathumbu: I-stents yamathumbu isetyenziswa ngokuqhelekileyo ukunyanga izizathu ezahlukahlukeneyo ze-intestinal stenosis, ezifana ne-intestinal tumors, izifo zesisu ezivuthayo (ezifana nesifo sikaCrohn, isifo se-ulcerative colitis), ukungahambi kakuhle kwamathumbu emathunjini, njl njl. ezifana neentlungu zesisu, ukuqhina, ukuqunjelwa, nokukhokelela ekuthinteleni kwesisu. Ukufakelwa kwamathumbu e-intestinal stents kunokubuyisela i-patency yamathumbu aqhelekileyo ngokuhlanjululwa kunye nenkxaso.

Ukuvalwa kwamathumbu: I-stents zamathumbu zingasetyenziselwa ukunyanga ukuvaleka kwamathumbu okubukhali okanye okungapheliyo. Ukuvaleka kwamathumbu kubhekisela ekuthinteleni kwendawo ethile yamathumbu, okubangela ukuba iziqulatho zesisu zingakwazi ukudlula ngokuqhelekileyo. Ukuthintela kunokubangelwa ngamathumba, ukunamathela, ukuvuvukala, njl.

Iingxaki zasemva kotyando: I-stents yamathumbu inokuthintela okanye ukulawula iingxaki emva kokuhlinzwa emva kokuhlinzwa kwamathumbu. Kwezinye iimeko, ukubunjwa kwamathumbu emathunjini emva kokuhlinzwa kunokukhokelela kwi-intestinal stenosis okanye ukuphazamiseka. Ukufakelwa kwamathumbu e-intestinal stents kunokuphepha okanye ukunciphisa ukuvela kwezi ngxaki kunye nokugcina i-intestinal patency.
