Postoperative complications in colorectal surgery can be a serious concern, often leading to increased morbidity and mortality. Identifying reliable biomarkers to predict and detect these complications early on is crucial for improving patient outcomes. This study focuses on serum calprotectin, a potential biomarker for postoperative complications.
Calprotectin, an S100 protein, has shown promise in various inflammatory diseases and conditions. The aim of this pilot study was to define the normal postoperative dynamics of serum calprotectin and compare it with other established biomarkers like white blood cell count, C-reactive protein, lactate, and procalcitonin. The study also aimed to explore the potential of serum calprotectin as an early indicator of postoperative complications.
The study included 56 patients who underwent colorectal surgery. The results showed a significant increase in serum calprotectin levels postoperatively, similar to the trends observed for white blood cell count and C-reactive protein. Interestingly, preoperative serum calprotectin levels were higher in patients with malignant diseases compared to those with benign conditions.
Furthermore, the study found that serum calprotectin levels were significantly higher in patients who experienced postoperative complications on the first and fifth postoperative days. This suggests that serum calprotectin could be a valuable marker for detecting systemic inflammation and potentially predicting postoperative complications.
While the study has limitations, such as a small sample size and heterogeneous surgical procedures, the findings indicate that serum calprotectin may be a promising biomarker for future research, especially given its specificity for intestinal inflammation. Further larger-scale studies are warranted to validate these initial findings and explore the full potential of serum calprotectin as a diagnostic tool in colorectal surgery.
