ARTICLE HIGHLIGHTS
Research background
Intraperitoneal contamination leads to increase in levels of C-reactive protein (CRP), lactate, neutrophils and lead to decrease in levels of lymphocytes and albumin. Hajibandeh index (HI), which includes CRP, neutrophils and lactate as nominators and albumin and lymphocytes as denominators, has been developed to predict peritoneal contamination and postoperative mortality in patients with acute abdominal pathology.
Research motivation
Presence of intraperitoneal contamination is an important predictor of morbidity and mortality in patients with acute abdominal pathology and it is taken into account by preoperative prognostic scoring tools. Therefore, early detection of intraperitoneal contamination is very important.
Research objectives
The objective of the study was to validate accuracy of HI in predicting the presence and nature of peritoneal contamination in patients with acute abdominal pathology.
Research methods
The STROBE guidelines and the PRISMA statement standards were followed to conduct a cohort study and a meta-analysis, respectively. The accuracy of the HI was evaluated using receiver operating characteristic curve analysis in the cohort study and using weighted summary area under the curve (AUC) under the fixed and random effects modelling in the meta-analysis.
Research results
Analysis of 1437 patients showed that HI can accurately predict the presence of peritoneal contamination in patients with acute abdominal pathology (AUC: 0.79, 95% confidence interval: 0.75-0.83).
Research conclusions
The HI is a strong and accurate predictor of intraperitoneal contamination in patients with acute abdominal pathology.
Research perspectives
HI is an objectively derived index from basic biomarkers and is worth attention for inclusion in emergency laparotomy preoperative risk assessment tools. It is a strong predictor of intraperitoneal contamination and postoperative mortality. The available evidence is robust but is limited to the studies conducted by our evidence synthesis group. The predictive performance of HI needs to be externally validated by other researchers.
