However, its intensity and duration can depend on the type of surgery, location of the procedure, and the individual characteristics of the patient. shortening the recovery period and improving the overall well-being of the patient. The aim of this study was to identify factors that exacerbate pain in adult patients following surgical treatment

Material and methods:
A retrospective analysis of medical records was conducted for patients who underwent surgery for colorectal cancer over a period of 6 months. The study included 117 patients. Statistical analysis of the study results was performed using IBM SPSS Statistics

Results:
Nearly 95% of patients experienced pain after surgery. It was identified that the following factors contributed to increased pain perception: pre-operative systemic treatment (p = 0.017), high risk of post-operative wound infection (p = 0.022), surgical method – laparotomy (p = 0.018), and body mass index (BMI) value (p = 0.012).

Conclusions:
Post-operative pain is one of the most significant problems after surgery. Factors influencing increased pain sensations have been identified, such as: BMI value, surgical method, risk assessment of infection, and systemic treatment used before surgery. The primary aim of post-operative management is to eliminate unnecessary suffering, provide comfort, and facilitate recovery
