Measurement of CRP on the third postoperative day in patients undergoing elective colorectal surgery with primary or secondary anastomosis allows the identification of septic complications including leakage of anastomosis.
Introduction:The anastomotic leakage (AL) in colorectal surgery is a complication feared by the increase in morbidity and mortality. The rate of AF is reported from 1 to 25%. Making the diagnosis early is difficult. Objective: To determine the diagnostic performance of the C reactive protein (CRP) in a cohort of patients undergoing elective colorectal surgery with anastomosis. Method: A prospective, comparative study was conducted in 138 patients undergoing elective anastomosis with colorectal surgery, analyzing the serum values of CRP on postoperative days 1, 3, 5 and 7, as well as leukocytes and other abdominal sepsis data. Results: The AL rate was 6.5%, the CRP values were significantly higher in the group of patients with AF on the 3rd postoperative day; with a cut-off point of 18.5 mg/dl on the third postoperative day, it obtained sensitivity 81%, specificity 91%, positive predictive value 45%, negative predictive value 98%. Conclusion: Measurement of CRP on the third postoperative day in patients undergoing elective colorectal surgery with primary or secondary anastomosis allows the identification of septic complications including leakage of anastomosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
