RESUMO
Recently, it was reported that abdominal infection affected the survival rate after colorectal cancer surgery. We retrospectively assessed the risk factors for complications related to infection after obstructive colorectal cancer surgery. In the multivariate analysis, the following variables were found to be independent risk factors for complications related to infection after obstructive colorectal cancer surgery: PNI(p=0.02, OR=14.5)and the duration of surgery(p<0.01, OR=24.0). In addition, the lack of improvement of PNI after preoperative decompression led to an increase in the incidence of complications related to infection after surgery. Therefore, efforts should be made to prevent prolonged duration of surgery and thereby, improve preoperative nutrition while choosing the appropriate method for obstructive colorectal cancer surgery.
