Disposable Polypectomy Snare oval, tus endoscopist txhim kho lub snare sheath, qhib lub snare thiab encircles lub polyp. Lub snare yog maj mam thiab maj mam kaw, nrog rau lub hom phiaj ntawm kev ntes 1-2 hli ntawm ib txwm cov ntaub so ntswg nyob ib ncig ntawm lub polyp, ces siv Electrocoagulation kom txog thaum tiav kaw tiav thiab cov polyp yog guillotined. Tom qab ntawd cov polyp tuaj yeem raug nqus thiab muab rov qab rau kev ntsuas histological.

 

Disposable Polypectomy Snare oval, uas yog siv electrocoagulation nyob rau hauv lub hauv paus ntawm kev siv txias snare.Tom qab HSP, lwm tus kws phais endoscopic ywj siab txiav txim seb qhov endoscopic eradication puas tau. Tom qab ntawd, EMR ntxiv tau ua nyob rau ntawm qhov chaw polypectomy los ntsuas qhov muaj cov ntaub so ntswg polyp, nrog rau qhov ntxiv 1 mus rau 2 hli cov npoo ntshiab, tau muab tshem tawm los ntawm cov snare thiab Endocut tam sim no tom qab txhaj tshuaj submucosal ntawm cov tshuaj tov. Yog tias tsis muaj cov ntaub so ntswg raug tshem tawm lossis yog tias EMR tsis tuaj yeem nkag mus rau hauv cov kab mob mucosal. Yam tsawg kawg yog plaub qhov kev kuaj mob khaub thuas uas siv forceps ntawm cov npoo seem tau txais. Tom qab txhua tus txheej txheem, qhov chaw polypectomy tau soj ntsuam rau 30 vib nas this kom paub meej tias qhov tsis tuaj yeem los ntshav tam sim ntawd, cov qauv tau muab khaws cia hauv formalin. Hla ntu ntawm cov qauv EMR tau sau ntawm 1- hli ntu; cov ntaub so ntswg raug ntawm qhov chaw cim tau raug lees paub.

 

Kev mob qog nqaij hlav hauv plab (CRC) yog qhov thib peb feem ntau mob qog noj ntshav hauv Asmeskas nrog 135 - 420 tus neeg mob tshiab hauv ib xyoos 1. Kev tshuaj xyuas colonoscopy nrog polypectomy txo qis CRC qhov xwm txheej thiab kev tuag 2 3. Txawm li cas los xij, qhov kev xav tau siab ntawm qhov tsis tiav ntawm qhov kev txiav tawm ntawm txoj hnyuv loj tau raug tshaj tawm nyob rau hauv qee qhov kev tshawb fawb tsis ntev los no, thiab qhov no tau cuam tshuam txog kev pheej hmoo siab dua tom qab colonoscopy interval CRC 4. Diminutive (< 5 mm) and small (6 – 9 mm) polyps represent the vast majority of polyps removed at screening colonoscopy 5. In theory, two major techniques are available for these lesions, namely biopsy-forceps polypectomy and snare polypectomy. The former, however, has been associated with a much higher rate of incomplete resection, especially for small polyps, and its use is not generally recommended 6. The latter may be further classified into hot (HSP) and cold (CSP) snare polypectomy. The basic difference is the use of a high frequency generator for HSP. Such use may, on the one hand, minimize immediate post-polypectomy bleeding by coagulation, but, on the other, it may also damage deeper vessels with increased risk of delayed bleeding 7 8 or even perforation. For this reason, CSP is usually considered safer, while resulting in equivalent rates of complete resection, and its use has dramatically increased in recent years 9 10 11 12, due also to the development of specific CSP-snares. CSP- and HSP-incomplete resection rates (IRR) for ≤ 10 mm polyps range widely, being 0.5 – 6.4 % and 1.2 – 7.4 %, respectively 12 13 14 15, and these estimates are much lower compared with forceps-polypectomy 6 16. However, any advantage of one technique (HSP vs. CSP) over the other remains unclear 17.
