I-endoscopic biopsy yeyona nxalenye ibalulekileyo yovavanyo lwemihla ngemihla lwe-endoscopic. Phantse zonke iimvavanyo ze-endoscopic zifuna inkxaso ye-pathological emva kwe-biopsy. Umzekelo, ukuba i-mucosa yomgudu wokugaya ukutya irhanelwa ukuba inokuvuvukala, umhlaza, ukushwabana, i-metaplasia yamathumbu, kunye nosulelo lwe-HP, i-pathology iyadingeka ukuze kufumaneke iziphumo eziqinisekileyo.
Okwangoku, iindlela ezintandathu ze-biopsy zenziwa rhoqo eTshayina:
1. Uvavanyo lweCytobrush
2. Uvavanyo lweTishu
3. Indlela yokuchonga i-tunnel biopsy
4. I-EMR esebenzisa indlela ye-bulk biopsy
5. Indlela ye-biopsy yethumba elipheleleyo i-ESD
6. I-FNA ekhokelwa yi-ultrasound
Namhlanje siza kugxila ekuphononongeni i-tissue biopsy, eyaziwa ngokuba yi-"clamping a piece of meat".
I-biopsy phantsi kwe-endoscopy yokugaya ayinakwenziwa ngaphandle kwe-biopsy forceps, ekwayenye yezona zinto zisetyenziswa kakhulu ngootitshala abangongikazi be-endoscopic. Ootitshala ababandakanyeka kunyango lwe-endoscopic basenokucinga ukuba i-biopsy forceps kulula kakhulu ukuyisebenzisa, ilula njengokuvula nokuvala. Enyanisweni, ukuze umntu asebenzise i-biopsy forceps ngokucacileyo nangokugqibeleleyo, kufuneka abe nolwazi kunye nomsebenzi onzima, kwaye abe nobuchule ekushwankatheleni.
I.Okokuqala, masihlolisise ulwakhiwo lwei-biopsy forceps:
(I) Ulwakhiwo lwe-biopsy forceps (Umfanekiso 1): I-Biopsy forceps yenziwe yincam, umzimba kunye nesiphatho sokusebenza. Izixhobo ezininzi ezifana ne-external body forceps, i-hot biopsy forceps, izikere, ii-curettes, njl.njl. ziyafana nolwakhiwo lwe-biopsy forceps.
Icebiso: Incam yenziwe yimihlathi emibini efana nekomityi enokuvulwa kwaye ivalwe. Imilo yemihlathi yeyona nto iphambili ekusebenzeni kwe-biopsy forceps ezahlukeneyo. Zinokwahlulwa zibe ziintlobo ezisixhenxe: uhlobo oluvulekileyo olunye, uhlobo oluvulekileyo kabini, uhlobo lwefestile, uhlobo lwenaliti, uhlobo oluyi-oval, uhlobo lomlomo wengwenya, kunye nohlobo olugobileyo lwencam. Imihlathi ye-biopsy forceps yenziwe ngentsimbi engatyiwayo kwaye ineeblade ezibukhali. Nangona iiblade ze-biopsy forceps ezilahlwayo nazo zibukhali, azinawo amandla okuguguleka. Iiblade ze-biopsy forceps eziphinda zisetyenziswe ziphathwe ngokukodwa kumphezulu ukuze zihlale ixesha elide.
Iindidi eziqhelekileyo zei-biopsy forceps
1. Uhlobo oluqhelekileyo olunefestile
Kukho ifestile embindini wekomityi ye-forceps, enciphisa kakhulu umonakalo wezicubu kwaye yonyusa ubungakanani bezicubu ze-biopsy.
2. Uhlobo oluqhelekileyo olunefestile kunye nenaliti
Inaliti ibekwe embindini wekomityi ye-forceps ukuthintela ukuba i-biopsy ingatyibiliki kwi-mucosa kwaye incede ekubambeni isampuli yezicubu.
3. Uhlobo lwengwenya
Ikomityi ye-clamp erhabaxa ithintela ngempumelelo ikomityi ye-clamp ekutyibilikeni, kwaye umphetho wokusika ubukhali ukuze ubambeke ngokukhuselekileyo.
4. Uhlobo lwengwenya enenaliti
Imihlathi ine-engile ebanzi yokuvula ukwandisa umthamo we-biopsy; umphetho we-blade ubukhali ukuze ubambeke ngokukhuselekileyo.
Kukho inaliti embindini wentloko ye-clamp, enokwenza ukuba i-fixation isebenze ngakumbi kwaye ichaneke.
Ifanelekile kwi-biopsy kwiithishu eziqinileyo ezifana neethumba.
Umzimba we-Forceps: Umzimba we-biopsy forceps wenziwe ngetyhubhu yentsimbi engagqwaliyo, equlethe ucingo lwentsimbi lokutsala ivalvu ye-forceps ukuze ivuleke kwaye ivalwe. Ngenxa yesakhiwo esikhethekileyo setyhubhu eneentambo, i-tissue mucus, igazi kunye nezinye izinto zinokungena ngokulula kuyo, kodwa akulula ukuyicoca kakuhle. Ukungaphumeleli ukuyicoca kakuhle kuya kubangela ukuphazamiseka ekusebenzeni kwe-biopsy forceps, kwaye ukuvulwa nokuvalwa akuyi kuba buthuntu okanye akunakwenzeka ukuyivula. Isiphatho sokusebenza: Indandatho ekwisiphatho sokusebenza isetyenziselwa ukubamba ubhontsi, kwaye umngxuma obanzi ojikelezayo usetyenziselwa ukubeka umnwe wokukhomba kunye nomnwe ophakathi. Phantsi kokusebenza kwale minwe mithathu, amandla adluliselwa kwi-forceps valve ngentambo yokutsala ukuze ivuleke kwaye ivalwe.
(II) Amanqaku aphambili okusetyenziswa kwe-biopsy forceps: Kufuneka kuthathwe unonophelo olukhulu ekusebenzeni, ekusetyenzisweni nasekugcinweni kwe-biopsy forceps, kungenjalo kuya kuchaphazela ukusetyenziswa kwe-endoscope.
1. Ukuchonga kwangaphambili:
Ngaphambi kokuba uyisebenzise, qiniseka ukuba ii-forceps ze-biopsy zicociwe kwaye zisetyenziswe ngexesha elifanelekileyo lokubulala iintsholongwane. Ngaphambi kokufaka itshaneli ye-endoscope forceps, kufuneka kuvavanywe ukuvulwa nokuvalwa kwee-forceps (Umfanekiso 2).
Umfanekiso 2 Ukufunyanwa kwe-Biopsy forceps
Indlela ethile kukubopha umzimba we-biopsy forceps ube yisangqa esikhulu (ububanzi besangqa bumalunga ne-20cm), uze wenze amanyathelo amaninzi okuvula nokuvala ukujonga ukuba ii-forceps flaps ziyavuleka kwaye zivale kakuhle na. Ukuba kukho ukungagudi kabini, kungcono ungayisebenzisi i-biopsy forceps. Okwesibini, kuyimfuneko ukuvavanya ukuvalwa kwe-biopsy forceps. Thatha iphepha elincinci njengephepha leleta uze ulibambe nge-biopsy forceps. Lifanelekile ukuba iphepha elincinci aliwi. Okwesithathu, kuyimfuneko ukuqwalasela ukuba iikomityi ezimbini ze-forceps flaps zilungelelaniswe ngokupheleleyo na (Umfanekiso 3). Ukuba kukho ukungalungi kakuhle, yeka ukuyisebenzisa ngoko nangoko, kungenjalo iya kukrwela umbhobho we-forceps.
Umfanekiso 3 I-Biopsy forceps flap
Amanqaku ngexesha lokusebenza:
Ngaphambi kokufaka ityhubhu ye-forceps, imihlathi kufuneka ivalwe, kodwa khumbula ukuba ungasebenzisi amandla amaninzi ngenxa yokoyika ukuvalwa okukhululekileyo, okuya kubangela ukuba ucingo lokutsala lutsalwe kwaye luchaphazele ukuvulwa nokuvalwa kwemihlathi. 2. Xa ufaka ityhubhu, ngena kwicala lokuvulwa kwetyhubhu ye-forceps kwaye ungakhuhli ukuvulwa kwetyhubhu. Ukuba ufumana ukumelana xa ungena, kufuneka ukhulule iqhosha le-engile kwaye uzame ukungena ngendlela ethe tye ngokwendalo. Ukuba awukwazi ukudlula, rhoxisa i-endoscope emzimbeni ukuze uyivavanye, okanye uyitshintshele kwezinye ii-forceps ze-biopsy ezifana neemodeli ezincinci. 3. Xa ukhupha ii-forceps ze-biopsy, kuphephe ukusebenzisa amandla agqithisileyo. Umncedisi kufuneka ayibambe ngezandla zombini ngokutshintshana aze ayigobe. Musa ukuzolula iingalo zakho kakhulu. 4. Xa imihlathi ingenakuvalwa, musa ukuyikhupha ngenkani. Ngeli xesha, kufuneka ityhalelwe ngaphandle komzimba kunye ne-endoscope ukuze kuqhutyekwe phambili.
II. Isishwankathelo sezinye iindlela zokusebenzisa i-biopsy
1. Ukuvula nokuvala i-biopsy forceps zombini ziimisebenzi zobugcisa. Ukuvula kufuna ulwalathiso, ingakumbi i-engile yesisu, ekufuneka ihlale ithe nkqo kwindawo ye-biopsy. Ukuvala kufuna ixesha. Ukunyakaza kwesisu kunye notyando lukagqirha zizinzile kwaye azinakulungiswa rhoqo. Umncedisi kufuneka asebenzise eli thuba ukuze abambe i-biopsy forceps ngempumelelo nangokukhuselekileyo.
2. Isampuli ye-biopsy kufuneka ibe nkulu ngokwaneleyo kwaye inzulu ngokwaneleyo ukufikelela kwi-mucosa yemisipha.
3. Cinga ngempembelelo yokopha emva kokuxilongwa kwe-biopsy kwi-biopsy elandelayo. Xa i-engile yesisu kunye ne-antrum kufuneka zihlolwe ngaxeshanye, i-engile yesisu kufuneka ihlolwe kuqala, uze emva koko uhlolwe i-antrum; xa indawo yesilonda inkulu kwaye iziqwenga ezininzi zezicubu kufuneka ziboshwe, iqhekeza lokuqala kufuneka libe chanekileyo, kwaye kuyimfuneko ukuqwalasela ukuba ukopha emva kokuxilongwa kuya kuzigubungela na izicwili ezijikelezileyo kwaye kuchaphazele intsimi yokubona, kungenjalo ukuxilongwa okulandelayo kuya kuba yimfama kwaye kungenzi nto.
Ulandelelwano oluqhelekileyo lwe-biopsy yezilonda kwi-engile yesisu, kuthathelwa ingqalelo impembelelo yokuhamba kwegazi kwii-biopsies ezilandelayo
4. Zama ukwenza i-biopsy yoxinzelelo oluthe nkqo kwindawo ekujoliswe kuyo, kwaye usebenzise ukufunxa xa kuyimfuneko. Ukufunxa kunciphisa uxinzelelo lomphezulu we-mucosa, okuvumela ukuba izicubu zibambeke nzulu kwaye zingatyibiliki lula.
I-Biopsy kufuneka yenziwe ngokuthe nkqo kangangoko kunokwenzeka, kwaye ubude bolwandiso lwe-forceps ye-biopsy akufuneki budlule kwi-2CM.
5. Nika ingqalelo ekukhetheni iindawo zokuthatha iisampulu kwiintlobo ezahlukeneyo zezilonda; ukhetho lwamanqaku okuthatha iisampulu luhambelana nesantya esihle. Ugqirha wotyando uneliso elibukhali kwaye kufuneka anike ingqalelo nakwizakhono zokukhetha izixhobo.
Iindawo ekufuneka zihlolwe iibhayopsi Iindawo ekufuneka zingahlolwa iibhayopsi
6. Iindawo ekunzima ukuzisebenzisa xa uxilonga ziquka i-fundus yesisu kufutshane ne-cardia, ukugoba okuncinci komzimba wesisu kufutshane nodonga olungasemva, kunye nekona ephezulu ye-duodenum. Umncedisi kufuneka agxile ekusebenzisaneni. Ukuba ufuna ukufumana iziphumo ezigqibeleleyo, kufuneka afunde ukucwangcisa kwangaphambili aze alungise indlela i-clamp flap ebekwe ngayo nangaliphi na ixesha. Kwangaxeshanye, kufuneka agwebe ngokukhawuleza ixesha lokuxilonga ngokusebenzisa onke amathuba. Ngamanye amaxesha xa elinde imiyalelo evela kugqirha wotyando, ukulibaziseka komzuzwana omnye kunokukhokelela kumathuba alahlekileyo. Ndingalinda ngomonde ithuba elilandelayo.
Iintolo zibonisa iindawo apho kunzima ukufumana izinto okanye apho kunqandwa khona ukopha.
7. Ukukhethwa kwee-forceps ze-biopsy: Ii-forceps ze-Biopsy ziquka ezo zinemingxunya emikhulu yekomityi kunye nezinzulu, ezinye zineenaliti zokubeka indawo, kwaye ezinye zinemingxunya ecaleni kunye nokuluma okunezikhonkwane.
8. Ukukhulisa kunye nokufaka imibala nge-elektroniki ukuze kuqondiswe i-biopsy kuchaneke ngakumbi, ingakumbi xa kuthathwa isampuli ye-esophageal mucosa.
