Txhawm rau txo qhov tshwm sim thiab kev tuag ntawm tus mob qog nqaij hlav hauv plab, mob khaub thuas snare polypectomy (CSP), ib qho ntawm cov txheej txheem endoscopic resection, tau raug qhia rau kev tshem tawm cov polyps me me (5 hli) los yog noncancerous polyps txog li 10 hli. ] CSP tau nce siab me ntsis tsis ntev los no. Cov lus qhia, kev ua tau zoo, kev nyab xeeb, thiab kev txhim kho ntawm CSP yog nyob rau hauv daim ntawv tshaj tawm no.
European Society of Gastrointestinal Endoscopy (ESGE) Clinical Guideline qhia CSP raws li txoj kev nyiam rau kev txiav tawm ntawm me me polyps (5 hli), raws li nws ua tiav tus nqi siab ntawm kev ua tiav resection, qis tus nqi ntawm cov teeb meem, thiab tso cai rau cov ntaub so ntswg txaus sampling rau histology. (Cov pov thawj zoo, muaj kev pom zoo).[1] Cov txiaj ntsig ntawm ntau qhov kev sib tw, ib lub chaw sim ntawm cov me me polyps (10 hli) tau pom tias CSP tuaj yeem ua tau raws li cov txheej txheem rau kev tshem tawm histological, kev nyab xeeb, thiab ceev ceev. CSP rau sessile serrated polyps (SSPs) uas yog 6 mus rau 9 hli loj (Cov pov thawj zoo, tsis muaj zog pom zoo).
Rau polyps me dua 10 hli qhov loj me, ntau qhov kev tshawb fawb tau ua los ntsuas qhov tshwm sim ntawm qhov txias snare resection.[4] Cov kev tshawb pom tau pom tias kev siv CSP muaj 99.3 feem pua ntawm kev tshem tawm tag nrho, uas txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim tsis zoo tsis tau nce ntxiv. Qhov feem pua ntawm cov polyps tseem tshuav (4.1 feem pua) thiab tus nqi rov ua dua (12.2-13.8 feem pua ) yog ob qho tib si siv tau, raws li kev soj ntsuam cov colonoscopies. Nonpedunculated Loj Colon Polyps kuj tsis ntev los no tau kho nrog Wide-field Piecemeal CSP. Cov txiaj ntsig ntawm qee qhov kev tshawb fawb tau pom tias CSP yog ib txoj kev nyab xeeb thiab ua tiav cov txheej txheem rau kev tshem tawm cov kab mob hauv plab loj dua 10 hli, txawm hais tias cov ntaub ntawv rau nws cov txiaj ntsig ntawm kev tshem tawm cov polyps loj yog tam sim no sparse.
