The aim of the study was analysis of the number of resection and palliative procedures in patients operated on for colorectal cancer in Poland. We also analyzed the number of sphincter-sparing surgery in patients with rectal cancer.Material and methods. Statistical data about surgical procedures performed in patients with colorectal cancer were obtained from the National Institute of Hygiene in Warsaw. The procedures were divided into palliations and resections. The analysis was performed for the period from 2005 to 2008. We analyzed the data including women and men.Results. We observed an increase in the number of resections from 3381 to 3768 (85.6-88% of all treatments) (2005-2008) in patients with colon cancer. A similar regularity was observed in patients who underwent surgery for rectal cancer from 2335 to 2712, respectively (76.4 to 81.4% of all treatments). Similarly, the number of sphincter-sparing surgery over the course of the period has increased from 1502 to 1916 operations.Conclusions. The increase in the percentage of resections and sphincter-sparing surgery may indicate the progress in the earlier detection of colorectal cancer. Another reason for this increase may be improving the level of education of surgeons due to the better availability of workshops and training. However, analysis is based on too short period of time and these conclusions cannot be regarded as final.
