Ukuvikelwa kwe-Colorectal anastomosis ubufakazi bokuvuza obumbozwe ngokugcwele

Isingeniso Somkhiqizo
Lesi i-stent esikhethekile esimbozwe ngokugcwele esisebenzisa ama-staplers okuhlinzwa ukuze kukhishwe umdlavuza wamabele kanye nokuthunga. Kuyi-stent ehlosiwe yokuvikela ukuvuza kwe-anastomotic esheshisa ukuphulukiswa kwe-anastomotic futhi ivimbele ukuvuza kwe-anastomotic. Le stent ihlukile kune-stoma futhi ayidingi i-suturing. Ifakwe ngendlela engavamile futhi ukuhlinzwa kubuyiselwa emuva ngokuphelele. Kungenziwa uphawu olungenalutho ku-stent ukuze kuqinisekiswe ngempumelelo ukuthintana phakathi kwendle nesizinda se-anastomotic, kuqinisekiswe ukuthi uketshezi lomzimba luyaphuma emgodini obambekayo. Izohlala isendaweni kuze kube yilapho inqubo yokuphulukisa yemvelo nokulungisa izicubu zomzimba isiqediwe (cishe amasonto amabili), bese izosuswa ngokuhlinzwa kwe-endoscopic ngaphandle kwesidingo sokungenelela okwesibili kokuhlinzwa. Lokhu kuqeda isidingo sokuba iziguli zibekezelele ubuhlungu bendunu yokwenziwa nokugqoka izikhwama zokwenziwa. Ingasuswa ezinsukwini ezingu-10, futhi isiguli singakwazi ukuqhubeka nempilo evamile
Ukusetshenziswa Okuhlosiwe
Isigameko sokuvuza kwe-anastomotic ngemva kokuhlinzwa komdlavuza we-colorectal singama-5% kuya ku-15%. Uma ukuvuza kwe-anastomotic kwenzeka, akuthinti nje kuphela ukululama kwesiguli ngemva kokuhlinzwa futhi kwandise isikhathi sokuhlala esibhedlela, kodwa futhi kudinga ukuvuselelwa njalo uma kunesidingo, ukwandisa ubuhlungu besiguli kanye nezindleko zokwelapha; Izimo ezinzima zingaholela ekushayweni kwe-septic noma ngisho nokufa; Ngesikhathi esifanayo, kungase futhi kuholele ezinkingeni zesikhathi eside ezifana ne-postoperative anastomotic stenosis kanye nokungasebenzi kahle kwe-defecation, okuthinta ikhwalithi yokuphila yesikhathi eside yesiguli. Indlela yokuvimbela ukuvuza kwe-anastomotic kusewukugxila nobunzima ocwaningweni lwezokwelapha ngaphakathi nangaphandle, futhi izixazululo ezanelisayo azikakatholakali. Lolu cwaningo lwamukela indlela entsha yokuvimbela, ebandakanya ukubeka isitezi samathumbu esibizwa ngokuthi "i-anastomotic leak proof protective stent" endaweni ye-anastomotic ngesikhathi sokuhlinzwa, ukuzuza imiphumela emihle.
Amaphuzu Obuchwepheshe
I-anastomotic stent eyenziwe ngokwezifiso inkampani yethu iwuhlobo olukhethekile lwe-stent yamathumbu, eyenziwe nge-nickel titanium memory alloy enesakhiwo se-mesh. Udonga lwangaphakathi lumbozwe ngefilimu esobala engangeni manzi, futhi i-stent inokubukeka okumise okwe-dumbbell okunomsele omncane phakathi nendawo. Bheka Umfanekiso 1. Ingxenye engenhla yabakaki inobude obungama-20mm futhi inobubanzi obungaphandle obungu-33mm, obuhambisana nobubanzi bangaphakathi bekholoni ye-sigmoid; Ingxenye engezansi inobude obungu-20mm futhi inobubanzi obungaphandle obungu-28mm, incane kancane kunobubanzi bangaphakathi bomkhawulo ongezansi we-rectum, ukuze okuqukethwe kwamathumbu okuqoqwe emseleni kukhishwe ngesikhathi esifanele. I-groove ingu-10mm ubude futhi inobubanzi obungaphandle obungu-20-25mm, obuhambisana nobubanzi bensika yokusika yezinhlobo ezahlukene zama-staplers amashubhu ukuze kuqinisekiswe ukuthi ukushuba kwe-radial kokuvuleka kwe-anastomotic akunyuki ngemva kokubekwa kukabakaki. Ngakho-ke, lapho ubeka ubakaki, ukufakwa kufanele kufakwe ku-groove. Ubakaki wangaphambili ucindezelwe ube yi-catheter enezingqimba ezimbili enobubanzi obungaphandle obungu-8mm, futhi ubakaki utholakala phakathi kwama-catheter angaphakathi nangaphandle. Ubakaki ukhishwa ngokuslayida ama-catheter angaphakathi nangaphandle.
