Аннотация: Aims To assess the usefulness of cold polypectomy of small colon polyps onthe basis of endoscopic microstructural analysis of the edges of the post-resectiondefect.Methods In 74 patients 103 colon polyps were detected. These were up to10 mm in size, without signs of severe dysplasia or cancer. Most of the polyps(81/103;78.7%) were of flat-elevated and were of polypoid 21/103;20.3%. Thepolyps were resected with a cold snare. A complete endoscopic analysis of themicrostructures and the capillary vessels of the mucosa was performed on theedge of the post-resection defect.Results The criteria followed post cold polypectomy in order to check its successwere: endoscopic visualization on the edge of the post-resection defect of1)parallel crypts and 2)the pit pattern of type I (S.Kudo). This was observed in93(90.3%) cases. In 10(9.7%) cases, single extended modified crypts werefound, with violation of their parallelism, which was a sign of residual tissue. Acombined removal technique was used – a cold snare, supplemented with biopsyforceps for the purpose of radical intervention. We noted differences in thelocation of the crypts of the rectum. In this area, the loss of parallelism of thecrypt is determined; the irregularity of the structure giving the impression of“falling crypts”. An endoscopic assessment of the capillary network of thecolon mucosa was performed. Flat-elevated polyps have capillary vessels thatare small in diameter, which significantly reduces the risk of bleeding. Followupcolonoscopies were performed on 11(10.7%) patients: no recurrence ofpolyps were detected.Conclusions An assessment of the edges of the post-resection defect of themucosa after cold polypectomy provides a reliable diagnosis of the completesuccess of the endoscopic intervention and the possibility of removing residualtumor tissue (if present) immediately after its completion, and therefore reducesthe number of recurrence of tumors.
