[Colonoscopy in the diagosis and treatment of the colon polypoid formations]

the estimation of endoscopic methods efficacy in diagnostics and treatment of colon polypoid neoplasm. The study was carried out in versatile city hospital.

5811 colonoscopies (CS) were executed in endoscopic department of versatile city hospital Nr. 2, Krasnodar during the period of 01.01.2011 -01.01.2012 years. There were 332 endoscopic loop polypectomies, and 12 endoscopic mucosal resections among 5811 CS.

The choice of endoscopic extraction method depended on neoplasm microscopic type and its histological structure according to pre-operated histological investigation. In the most cases the neoplasm Ip and Is types were extracted by loop polypectomy. In cases of III grade or more dysplasia in the neoplasm Ip and Is types had revealed the endoscopic mucosal resection was performed. The neoplasm IIa and IIb were extracted by the endoscopic mucosal resection. The presence of IIc component was assessed as a bad prognostic feature and only the dilatated loop biopsy was carried out. During the endoscopic extraction of 32 villous tumors of the colon (size of 17 ones was more than 3.0 cm, and 3 ones was more 5.0 cm) 2 complications occurred and an urgent surgery was carried out in 1 case. The following periods of endoscopic control were determined according to extracted polypoid neoplasm histological data: 1, 3, 6 and 12 months. The relapse absence was assessed not only visually, but by biopsy from colon mucosal scars.

patients with the colon polypoid neoplasm need the dynamic clinic endoscopic supervision because of increased risk of oncotransformation.
