Introduction: In the recent decades, the surgical treatment of colorectal neoplasms is further developed with a minimally invasive approach, following the complex approach, modern guidelines and classic oncological principles. Any conventional operation can be performed via laparoscopy and in addition to that it produces a better image of the pelvis. Thus, a high-quality surgery, with a maximal sphincter conservation, minimal blood loss and quicker recovery of the patients can be carried out.Aim: The aim of this study was to analyze factors influencing the period of gaining experience with laparoscopic colorectal resections. We evaluated this surgery performed in the Second Surgery at the „Alexandrovska` Hospital (March, 2013-Februrary, 2016) for a period of three years.Materials and Methods: 317 patients with colonic and rectal neoplasms were operated on. Their average age was 61.4 and the gender distribution was - 172 males (54.3%) and 145 females (45.7%). Laparoscopic approach was planned in 37 (11.7%) of them. The following factors were taken into consideration: location of the tumor, the need to use automatic devices, duration of the surgery, etc. The compared indicators, related to decision making for laparoscopic approach, are the technique used and the obtained result, the duration of the intervention, financial resources and the number of conversions.Results: There were 5 are rectal amputations (13.5%), 14 anterior resection (37.8%) and two intersphincteric resections with coloanal anastomosis (5.4%), 6 (16.2%) right hemicolectomies, 5 left colectomies (13.5%) and three sigma resections (8.1%). The average postoperative stay reported was 6.2 days. The mean operative time was 212 minutes. A steady tendency to reduce it was observed (from 330 to 120 min.). Due to the advanced process, conversion was performed in 5 cases (13.5%).Conclusion: The use of automatic stapling devices and high-energy hemostatic devices predetermines the higher cost of the laparoscopic surgery. It gives the advantages of less postoperative pain and shortened hospitalization. The longer training curve depends on resource availability and personal technical skills. This use of this metehod gives the necessary advantage to patients without oncological safety compromise.
