Background. NOSE in LS surgery of colorectal cancer seems to be an option for minimization of surgical trauma and
severity of postoperative period.
Aim. The aim of the study was to analyze our own experience in LS-surgery with NOSE.
Methods. 64 patients with T2-T4 CRC were included in the retrospective study. 2 comparable groups were formed
(32 patient each): LS-surgery of CRC with or without natural orifice extraction of specimen.
Results. In the issue 2 groups were comparable in terms of blood loss (121,5 vs 112 ml), operation time (163 vs
170,4 min) and average number of lymph nodes (22,2 vs 21,8). All resections were with negative margins (R0). Anastomoses
were formed with circular stapler, hand-shewn extracorporally or hand-shewn intracorporally with LS-technique
(NOSE-group only). In terms of postoperative complications both groups were comparable.
The postoperative pain (The Faces Pain Scale-Revised) was less in NOSE group (2,6 vs 4,2, p<0,05).
The cosmetic effect was better in NOSE group (22,2 vs 15,6 points, p<0,05).
