C-Reactive Protein Values After Colorectal Resection: Can We Discharge a Patient With a C-Reactive Protein Value >100? A Retrospective Cohort Study

BACKGROUND: C-reactive protein is a useful negative predictive test for the development of anastomotic leakage following colorectal surgery. Evolution of procedures (laparoscopy, enhanced recovery program, early discharge, complex redo surgery) may influence C-reactive protein values; however, this is poorly studied to date. OBJECTIVE: The aim of this study is to evaluate C-reactive protein as an indicator of postoperative complication and as a predictor for discharge. DESIGN: This is retrospective study of a consecutive monocentric cohort. SETTINGS: All patients undergoing a colorectal resection with anastomosis (2014–2015) were included. MAIN OUTCOMES MEASURES: C-reactive protein, leukocytosis, type of resection, and postoperative course were the primary outcomes measured. RESULTS: A total of 522 patients were included. The majority had either a colorectal (n = 159, 31%) or coloanal anastomosis (n = 150, 29%). Overall morbidity was 29.3%. C-reactive protein was significantly higher among patient having intra-abdominal complications at an early stage (day 1–2) (164.6 vs 136.2; p = 0.0028) and late stage (day 3–4) (209.4 vs 132.1; p 100 mg/L vs 6% with C-reactive protein
