IRIS Institutional Research Information System - AIR Archivio Istituzionale della Ricerca

IRIS è il sistema di gestione integrata dei dati della ricerca (persone, progetti, pubblicazioni, attività) adottato dall'Università degli Studi di Milano.

AIR nasce in UNIMI nel 2006 con lo scopo di raccogliere, documentare e conservare le informazioni sulla produzione scientifica dell'Università degli Studi di Milano e costituisce di fatto l'Anagrafe della ricerca dell'Ateneo.

Background: Early detection of anastomotic leakage after esophagectomy has the potential to reduce morbidity and mortality. Prompt suspicion of leak may help to exclude patients from fast-track protocols, thereby avoiding early oral feeding and early hospital discharge which could aggravate the prognosis of a clinically occult leak. Patients and methods: Observational retrospective cohort study. Patients with diagnosis of esophageal cancer who underwent elective minimally invasive esophagectomy were included. The following data were collected: age, gender, BMI, comorbidities, ASA score, tumor histology, TNM staging, use of neo-adjuvant therapy, type of operation, operative time, morbidity, and 90-day mortality. A panel of biomarkers including C-reactive protein (CRP), procalcitonin (PCT), white blood cells (WBC), and percentage of neutrophils (PN) were measured at baseline and on postoperative days 3, 5, and 7. Results: Two hundred forty-three patients operated between 2012 and 2017 were included in the study. Anastomotic leakage occurred in 29 patients. There was a statistical association over time between anastomotic leakage and CRP (p < 0.001), PCT (p < 0.001), WBC (p = 0.019), and PN (p = 0.007). The cut-off value of CRP on POD 5 was 8.3 mg/dL, AUC = 0.818, negative LR = 0.176. Conclusions: Increased serum CRP, PCT, WBC, and PN after minimally invasive esophagectomy are associated with anastomotic leakage. A CRP value lower than 8.3 mg/dL, combined with reassuring clinical and radiological signs, may be useful to exclude leakage on postoperative day 5.
