title: [Colon cancer - evaluation of complications and risks of planned resections].
abstract: BACKGROUND
  Resection procedures for colorectal cancer are burdened with a relatively high number of complications. The aim of this study is to define risk factors associated with the development of postoperative complications based on retrospective data analysis.
  
  
  METHODS
  From January 1 st 2007 to December 31st 2012, 1093 patients underwent surgery for colorectal cancer. Retrospectively, we selected a group of 406 patients who underwent planned, elective colon resection for colon cancer. Open surgery was performed in 158 patients (38.9%), laparoscopic resection in 248 patients (61.1%). Based on initial staging of the disease, there were 85 patients (20.9%) in stage I, 137 patients (33.8%) in stage II, 110 patients (27.1%) in stage III and 74 patients (18.2%) in stage IV. Postoperative complications were evaluated according to Clavien - Dindo classification.
  
  
  RESULTS
  Grade I complications were observed in 34 patients (8.4%), grade II in 25 patients (6.2%), grade III in 43 patients (10.6%), grade IV in 7 patients (1.7%) and grade V in 8 patients (2.0%). The highest incidence of complications was observed in left colon resection procedures (41.1%), open resections (39.8%), procedures lasting longer than 301 minutes (50%), patients older than 81 years (41.6%) and in procedures performed by the youngest, less experienced surgeon (40.6%).
  
  
  CONCLUSIONS
  Our results confirmed that the type and approach of surgical procedure, patients age and surgeons experience are risk factors associated with a higher incidence of postoperative complications. High-risk surgical patients should be operated on by experienced surgeon who regularly performs a high number of resection procedures.
