Kim JD, et al. - In the presence of high esophageal perforation and rupture (EPR) size and a high segmented neutrophil count percentage in the white blood cell test and differential, an increased mortality risk was evident. This study shows that delayed diagnosis does not hold statistical significance though it was considered an essential predictive factor in previous studies.

• This is a retrospective study of 79 patients with EPR who were managed based on the location and size of the EPR, their laboratory findings, and radiological findings.

• Surgery was performed in 39 patients; of whom 4 patients died.

• Nonsurgical management was received by 40 patients, of whom 3 patients died.

• The rest of the patients were discharged.

• There was correlation of mortality with the size of the EPR (> 25 mm) as well as with the segmented neutrophil count percentage (> 86.5%) in the white blood cell test and differential.
