Introduction: Intussuseptionisan emergency pediatric surgical cases that are common encountered. The most common complications are necrosis and perforation on Intussuseption. Intussuseption that occurs in premature infants often leads to misdiagnosed with necrotizing enterocolitis (NEC), that results in incorrect or delayed surgical intervention. We tried to replaced CRP parameters with NLR, take the consideration that NLR is sensitive to inflammation or infection, and many reports a positive correlation was found between CRP and NLR. This is the basis of our research to replace the C-Reactive Protein test with the routine Neutrophil to lymphocyte ratio. The purpose of this study is to determine the relationship between modified-LRINEC (Laboratory Risk Indicator for Necrotizing Fasciitis) score with intestinal viability in Intussuseptioncases in H. Adam Malik General Hospital, Medan. Method: This research is an analytic observational study with cross sectional design, which was carried out in the Pediatric Surgery Division of the Department of Surgery at the Haji Adam Malik General Hospital Medan, by collecting samples from the medical records of Intussuseption patients starting from January 2016 to December 2018 that met the inclusion and exclusion criteria. Data processing was carried out using statistical tools of the SPSS program followed by the Komogorov-smirnov test. Descriptive analysis was performed to see the mean values and standard deviations of several parameters with numeric scales and percentages for categorical scale data. Results: Our research showed the relationship between the modified-LRINEC score in the viable intestine group there were 9 patients in a viable intestine, while the modified-LRINEC score 6-7 there were 2 patients with viable intestine and 5 patients with non viableAnd in the modified-LRINEC score ≥8 there were 8 patients were nonviable intestine. This data obtained statistically significant results, with p value <0.005. Hypothesis 0 was rejected in this study. Conclusions: There was a correlation between LRINEC score modification and intestinal viability in Intussuseption patients at H. Adam Malik General Hospital Medan.
