Ama-stents amathumbu angasetshenziswa ukwelapha izifo ezihlukahlukene zamathumbu, okuhlanganisa i-stenosis yamathumbu, umdlavuza we-colon, umdlavuza we-rectal, ukuvuza kwe-gastrointestinal, njll. Asebenzisa inhlobonhlobo yokusetshenziswa futhi angenziwa ngezifiso ukwenza izinhlelo zokwelapha ngokwezifiso.

Amanye ama-stents amathumbu angalungiswa ukuze avumelane nesimo esithile sesiguli. Ukwengeza, uma ukuvinjelwa kwamathumbu kukhululeka ngokuphelele noma i-stent ingasadingeki, ingaphinde ikhishwe ngokuphepha.

Isingeniso Somkhiqizo

I-intestinal stent iyisisetshenziswa sezokwelapha esisetshenziselwa ukwelapha ukuncipha nokuvinjelwa komgudu wokugaya ukudla. Ngokuvamile zenziwe ngezinto zensimbi noma ze-alloy, ezinesakhiwo senethiwekhi esingase sivuleke futhi sisekele izindawo ezincane.

Umsebenzi wama-stents wamathumbu ukunweba amathumbu amancane nokugcina amandla amathumbu. Uma umgudu wokugaya ukudla umncane noma uvimbekile, ukudlula kokudla noketshezi kukhawulelwe, okuholela ezinkingeni zokugaya ukudla kanye nokungakhululeki. Ukufakwa kwama-stents amathumbu kungabuyisela amandla ajwayelekile amathumbu, kuthuthukise izimpawu zeziguli kanye nezinga lempilo.

Ama-stents amathumbu angahlukaniswa abe izinhlobo ezahlukene ngokuya ngendawo yawo kanye nomsebenzi wawo. Ezinye izinhlobo ezivamile zama-stents amathumbu zihlanganisa:

I-Dynamic intestinal stent: Lesi stent singahlehla ngokuguquguqukayo ukuze sivumelane nezinguquko emathunjini futhi sigcine amandla amathumbu. Ngokuvamile zisetshenziselwa ukusetshenziswa isikhathi eside ukuze kuncishiswe isidingo sokusebenza kabusha.

I-stent yamathumbu ezikhulisayo: Lesi stent sisebenzisa izinto ezikhethekile ezingakwazi ukuzikhulisa futhi zandise umgudu wokugaya omncane emzimbeni.

I-stent yamathumbu ekhishwayo: Lesi stent singasuswa kalula ngodokotela uma sidingeka futhi ngokuvamile sisetshenziselwa ukwelashwa kwesikhashana.

Inqubo yokufakelwa kusetshenziswa ama-stents amathumbu ngokuvamile ayivamisile futhi ingenziwa ngokusebenzisa amasu afana ne-endoscopy. Ngemuva kokuhlinzwa, iziguli zingadinga ukuhlolwa njalo ukuze kuqinisekiswe ukusebenza kanye nokuma kwe-stent.

Sicela uqaphele ukuthi ukusetshenziswa kwama-stents amathumbu kudinga ukuhlolwa kukadokotela ngaphambi kokwenza isinqumo, futhi uhlelo lokwelapha olufaneleka kakhulu kanye nohlobo lwe-stent luzonqunywa ngokusekelwe esimweni esithile kanye nezidingo zesiguli. Uma uneminye imibuzo noma udinga imininingwane enemininingwane mayelana nomkhiqizo othile, sicela uthintane nodokotela noma isikhungo sezokwelapha esiqeqeshiwe.

UmkhiqizoIzici

I-intestinal stent idivayisi yezokwelapha esetshenziselwa ukwelapha ukuqina kwamathumbu noma ukuvinjelwa. Okulandelayo ezinye izici nezinzuzo zama-stents amathumbu, okuvumela izivakashi ukuthi zibe nokuqonda okuningiliziwe kolwazi lomkhiqizo:

Ukwesekwa okuqinile: I-stent yamathumbu yenziwe ngezinto ze-alloy eziguquguqukayo nezihlala isikhathi eside, ezinokusekela okwanele futhi ezingathuthukisa ngempumelelo ukuqina kwamathumbu. Idizayini ekhethekile yebakaki ivumela ukuthi ihambisane nokuma kwamathumbu, iqinisekise ukuzinza nokufaneleka.

Ukuthembeka kwesikhathi eside: Izinto zokwakha kanye nokwakheka kwe-stent yamathumbu kunikeza ukuqina okuhle kakhulu nokuzinza kwesikhathi eside. Ingahlala emathunjini isikhathi eside, isize ukubuyisela ukusebenza kwamathumbu, futhi inciphise izimpawu nokungakhululeki.

Ukuhlinzwa okungahlaseli: Uma kuqhathaniswa nezindlela zokuhlinza zendabuko, ukufaka ama-stents amathumbu ngokuvamile kuyinketho yokwelapha engahlaseli. Ifakwa ngokusebenzisa i-endoscopy noma indlela ye-percutaneous, ukugwema ubungozi kanye nesikhathi sokululama sokuhlinzwa okuvulekile.

Ukwenza kube ngokwakho: I-stent yamathumbu ingenziwa ngokwezifiso ngokuya ngesimo esithile sesiguli. Iziguli ezihlukene zingase zidinge osayizi abahlukene kanye nokuma kwama-stents ukuze zivumelane nendawo ye-intestinal stenosis.

Imiphumela yesikhathi esifushane neyesikhathi eside: Ukufakwa kwama-stents emathunjini kungathuthukisa ngokushesha ukuqina kwamathumbu futhi kudambise izimpawu. Kwezinye iziguli, ukusebenza kahle kwama-stents kungahlala iminyaka eminingana, kunciphisa isidingo sokwelashwa njalo.

Nakuba ama-stents amathumbu anezinzuzo eziningi, iziguli kufanele zithintane futhi zixoxisane nodokotela bazo ngokuningiliziwe lapho zikhetha izindlela zokwelapha. Isimo sesiguli ngasinye siyahlukahluka, futhi odokotela bazonquma ukuthi ingabe kufanelekile yini ukufaka ama-stents amathumbu ngokusekelwe ezidingweni zomuntu ngamunye kanye nemigomo yokwelashwa.

Isicelo

Ukusetshenziswa kwama-stents emathunjini kusetshenziselwa ikakhulukazi ukwelapha izimo ezilandelayo:

I-stenosis yamathumbu: Ama-stents amathumbu ngokuvamile asetshenziselwa ukwelapha izimbangela ezihlukahlukene ze-stenosis yamathumbu, njengezimila zamathumbu, izifo zamathumbu ezivuthayo (njenge-Crohn's disease, i-ulcerative colitis), ukungahambi kahle kwamathumbu emathunjini, njll. njengobuhlungu besisu, ukuqunjelwa, ukuqunjelwa, ngisho nokuholela ekuvinjweni kwamathumbu. Ukufakwa kwama-stents amathumbu kungabuyisela amandla ajwayelekile amathumbu ngokuvuleka nokusekelwa.

Ukuvinjwa kwamathumbu: Ama-stents amathumbu angasetshenziswa futhi ukwelapha ukuvinjelwa kwamathumbu okuyingozi noma okungapheli. Ukuvinjwa kwamathumbu kubhekisela ekuvinjweni kwengxenye ethile yamathumbu, okubangela ukuthi okuqukethwe kwamathumbu kungakwazi ukudlula ngendlela evamile. Ukuvinjelwa kungabangelwa izimila, ukunamathela, ukuvuvukala, njll. Ukufakwa kwama-stents emathunjini kunganciphisa ukuvinjelwa futhi kubuyisele i-patency evamile yamathumbu, kusize ukunciphisa izimpawu nokubuyisela ukusebenza kwamathumbu emathunjini.

Izinkinga zangemva kokuhlinzwa: Ama-stents amathumbu nawo angavimbela noma alawule izinkinga zangemva kokuhlinzwa ngemva kokuhlinzwa kwamathumbu. Kwezinye izimo, ukwakheka kwezicubu ezibomvu zamathumbu ngemva kokuhlinzwa kungase kuholele ekuqineni kwamathumbu emathunjini noma ekuvinjweni. Ukufakwa kwama-stents amathumbu kungagwema noma kunciphise ukuvela kwalezi zinkinga futhi kugcine amandla okuqina amathumbu.
