Introduction: Early safe discharge is paramount for the success of ERAS following colorectal cancer resections. Anastomotic leakage (AL) has high morbidity, particularly if the patient has been discharged to the community.
Aim: To evaluate whether C-reactive protein (CRP) and procalcitonin (PCT) can predict AL before early discharge.
Material and methods: Fifty-five consecutive patients undergoing open and robotic colorectal cancer resections were included. C-reactive protein and PCT were measured pre-operatively, 8 h after incision, and on the first and third postoperative day. Thirty-day readmissions, re-operations and mortality were recorded.
Results: Twenty-nine patients underwent robotic and the remainder open (n = 26) resections. Five patients had AL. The mean CRP and PCT increased on postoperative day 1 (POD 1) and POD 3 in all patients. On POD 3, mean CRP was 114 mg/l in non-AL patients and 321 mg/l in AL patients (p = 0.0001). Mean PCT on POD 3 was 0.56 ng/ml in the non-AL group and 10.4 ng/ml in AL patients (p = 0.017). On analysis of ROC and AUC curves, the cut-off for CRP on POD 3 was 245.64 mg/l, with 100% sensitivity and 98% specificity for AL. The cut-off for PCT on POD 3 was 3.83 ng/ml, with 75% sensitivity and 100% specificity for AL.
Conclusions: C-reactive protein and PCT measurement on POD 3 following colorectal cancer resection can positively identify patients at low risk of anastomotic leakage.
