Tam sim no, colonic polypectomy yog lub hauv paus ntawm lub plab hnyuv endoscopy, ua lub hauv paus rau kev kho mob ntau dua.
Ua ntej tshaj plaws,Dab tsi yog qhov tseem ceeb ntawm Kev Kho Mob ntawm Polypectomy?
Polypectomy pab peb lub hom phiaj tseem ceeb, uas yog
1. Kev tiv thaiv kab mob qog noj ntshav
2. Kev ntsuam xyuas kev kho mob zoo
3. Kev txiav txim siab ntawm cov tswv yim tshuaj ntsuam xyuas colonoscopy tom ntej
Qhov kev pheej hmoo stratification ntawm adenomas thiab cov kev pom zoo ntawm kev soj ntsuam lub sijhawm muaj feem cuam tshuam nrog cov hom phiaj no. Cov neeg mob uas tsis tshua muaj kev pheej hmoo feem ntau raug soj ntsuam xyuas colonoscopy hauv 5-10 xyoo, thaum cov neeg mob uas muaj kev pheej hmoo siab raug pom zoo rau kev soj ntsuam hauv 3 xyoos. Yog tias tsis pom qhov txawv txav thaum rov qab los, lub sijhawm yuav txuas ntxiv mus rau 5-10 xyoo.
Ua ntej ua polypectomy, nws yog ib qho tseem ceeb rau kev ntsuam xyuas cov yam ntxwv ntawm tus kab mob polyp. Lub zej zog Japanese endoscopy tau tsim ob txoj kev faib tawm raws li nqaim-band duab (NBI) nta: NICE (NBI International Colorectal Endoscopic) kev faib tawm thiab CP (Capillary Pattern) kev faib tawm.
Kev faib tawm NICE, uas tuaj yeem ua tau yam tsis muaj kev nthuav dav, categorizes polyps rau hauv peb hom raws li xim, qauv ntawm lub nkoj, thiab cov qauv saum npoo. Cov txheej txheem no yooj yim, siv tau, thiab siv tau yooj yim hauv chaw kho mob.
Kev faib tawm CP yuav tsum tau nthuav dav endoscopy thiab kev cob qhia ntau dua. Nws txawv ntawm neoplastic thiab non-neoplastic polyps raws li lub xub ntiag ntawm capillary tes hauj lwm thiab ntxiv qhov sib txawv ntawm qib qis thiab qib siab dysplasia lossis mob qog noj ntshav raws li capillary ntom thiab morphology.
Thib ob,Cov txheej txheem polypectomy feem ntau yog?
Kev xaiv ntawm cov txheej txheem polypectomy nyob ntawm polyp qhov loj, morphology, thiab qhov chaw. Cov txheej txheem muaj xws li:
1. Cold/Hot Forceps Polypectomy: Haum rau diminutive polyps (<5 mm). Hot forceps can address residual tissue and provide hemostasis but carries a risk of transmural injury if overused.
Daim duab yog los ntawm Internet. Yog tias muaj kev ua txhaum cai, thov hu rau peb kom tshem tawm.
2. Cold/Hot Snare Polypectomy: Tsim nyog rau ntau qhov ntau thiab tsawg ntawm pedunculated thiab me me sessile polyps (<2 cm). For larger pedunculated polyps (>2 cm), kub snare yog nyiam, nrog ceev faj kom tsis txhob sib cuag nrog lub plab hnyuv phab ntsa kom tiv thaiv tau thermal raug mob.
Daim duab yog los ntawm Internet. Yog tias muaj kev ua txhaum cai, thov hu rau peb kom tshem tawm.
3. Endoscopic Mucosal Resection (EMR): Qhia rau qhov chaw tiaj tus los yog tom qab kis kab mob mus txog 2 cm inch. Kev txhaj tshuaj submucosal elevates qhov txhab, ua kom muaj kev nyab xeeb dua thiab ua tiav kev phais.
Daim duab yog los ntawm Internet. Yog tias muaj kev ua txhaum cai, thov hu rau peb kom tshem tawm.
4. Endoscopic Submucosal Dissection (ESD): Ua hauj lwm rau cov kab mob loj dua 2 cm uas yuav tsum tau muab tshem tawm hauv bloc, cov uas muaj cov tsos mob tsis zoo, lossis mob qog noj ntshav thaum ntxov. Cov txheej txheem no nyuaj dua thiab ua rau muaj kev pheej hmoo siab dua ntawm cov teeb meem tab sis tso cai rau kev ua kom tiav thiab kev ntsuam xyuas pathological raug.
Daim duab yog los ntawm Internet. Yog tias muaj kev ua txhaum cai, thov hu rau peb kom tshem tawm.
5. Cov txheej txheem uas tsis yog-Resection: Kom paub qhov mob benign lossis qib qis, cov tswv yim xws li Argon Plasma Coagulation (APC), high-frequency electrocoagulation, los yog endoscopic ligation yuav raug siv los ua kom cov polyp tsis muaj cov ntaub so ntswg rov qab.
Thiab,cov ntsiab cai ntawm Safe and Effective Polypectomy
1. Kev npaj ua ntej yog qhov tseem ceeb, tshwj xeeb tshaj yog rau cov polyps complex. Kev sib txuas lus zoo nrog cov neeg saib mob thiab tshuaj loog thiab kev npaj cov cuab yeej tsim nyog yog qhov tseem ceeb.
2. Kev tuav tswj tau zoo maneuverability kom meej meej manipulation thaum lub sij hawm tus txheej txheem.
3. Kev npaj plab hnyuv kom txaus thiab kev pom tus neeg mob qhov chaw zoo yog qhov tseem ceeb rau kev pom pom tseeb thiab muaj kev nyab xeeb polypectomy.
4. Kev siv lub hau pob tshab tuaj yeem pab ua kom cov mucosal folds thiab tsim qhov chaw rau polyp manipulation.
5. Nyob rau hauv cov cheeb tsam uas loj luminal qhov chaw, xws li lub ascending nyuv thiab lub qhov quav, retroflexion ntawm endoscope yuav muab ib tug zoo saib ntawm polyp morphology thiab pab txoj kev npaj kho mob.
