Abstract
AIM: To optimize the indications for laparoscopic surgery in patients with locally advanced and prognostically unfavorable rectal cancer after neoadjuvant chemoradiotherapy. MATERIAL AND METHODS: 226 patients with locally advanced rectal cancer underwent combination therapy in A.F. Tsyba Medical Radiological Research Centre in 2003-2016. The patients were divided into two subgroups, depending on the surgical approach. The main group included 55 patients who underwent laparoscopic resections, and the control group included 171 patients - for conventional approach. RESULTS: In the subgroup of patients who underwent laparoscopic resections 42 (76.3%) organ preservation surgery were performed more often in comparison with the control subgroup 74 (43,2%) (p<0.0001). There were no significant differences in the incidence of intraoperative complications in both subgroups. The incidence of postoperative complications was lower in the laparoscopic approach group in comparison with the control group 12 (21.8%) patients and 62 (36.3%), respectively (p=0.0493). Data for local recurrence and dissemination of the process after surgery was not received. CONCLUSION: According to the main clinical and morphological features, laparoscopic resections may be an alternative, and in many cases even superior approach in comparison with the conventional surgery.
