The article presents retrospective analysis of complications of surgeries for non-organ-confined retroperitoneal tumors. The study includes information about 236 patients operated between 1996 and 2016 in Irkutsk Regional Cancer Center. All patients were divided into two groups: main group (n = 102] with resection of non-organ-confined retroperitoneal tumors in extended and combined version, and control group (n = 134] with isolated removal of tumor. The patients, who received combined version of operations, are presented in two groups (mono-organ resection group (n = 50] and multi-organ resection group (n = 52]]. Postoperative deaths and complications in these groups were analyzed. Clavien - Dindo classification was used in examining the structure of postoperative complications. 1t was established, that postoperative complications occurred in 44 (19 %] cases. The most frequent ones were intra-abdominal bleeding (3.8 %], wound infection (3 %], femoral nerve neuropathy (2.1 %] and abscess of abdominal cavity or small pelvis (2.1 %]. Among patients with isolated removal of non-organ-confined retroperitoneal tumors, post-operative complications made 14 % (16 cases]. Post-operative complications in the group with extended and combined resection of non-organ-confined retroperitoneal tumors reached 23 % (28 cases]. Accordingly, it was established that enhancing volume of surgery substantially increases frequency of post-operative complications (p = 0.02]. Surgical treatment of non-organ-confined retroperitoneal tumors involve developing post-operative complications of third degree, according to Clavien - Dindo classification. The complications demand invasive manipulation for their management. While examining the structure of extended and combined operations, in comparison with mono-organ resections, multi-visceral resections do not substantially increase the number of post-operative complications (p = 0.903). Most of complications were controlled and their timely management led to full recovery of patients.
