Transanal surgery in LST and early forms of rectum cancer



The question about local transanal tumor excision of the vining type of growth (LST) and rectum early cancer Tis-T2 remain to be of current interest today.

The aim of the analysis is to estimate the safety and efficiency of the LST and rectum early cancer excision using the methods of TEO and transanal excision by anoretractor.

Material and methods. 41 patients with LST and rectum early cancer (Tis-T2) were included to examinated group. During the prehospital stage 33 patients (80,4%) were diagnosed with tubulovillous-villiferous or villiferous-vining adenoma, 10 patients (24,4%) – adenocarcinoma Tis-T2. Average size of the tumor was 3,6±1,5 sm. All the patients were executed the full ply excision of the intestinal side with the tumor followed by suture of the wound.

Results. Totally 41 formations were extracted. Postoperative sequela occurred in 2 (4,9%) cases (1 – bleeding from postoperative wound, 1 – perforation of the intestinal side). 3 (7,3%) patients were determined with discrepancy of histological (tissular) examination of the biopsy and removed preparation. 4 patients (9,7%) had the relapse in the remote postoperative period. The received results let us make the conclusion that transanal tumor excision using anoretractor and operating proctoscope on the rigid platform (TEO) are effective and safe methods of the large villiferous adenoma surgery, LST and rectum early cancer.
