Wee JJ, et al. - Given the poorer clinical outcomes in correlation to perforated appendicitis vs non-perforated appendicitis and the complexity and difficulty encountered in reproducing previous attempts at the classification of severity, researchers here used another institution's (Jones et al., TX, USA) previously described simple classification system of peritoneal contamination and investigated its utility in predicting outcomes. They retrospectively reviewed the records of all pediatric patients operated at their institution for perforated appendicitis from 2016 to 2017 and identified 134 patients as eligible for this work. Categorization of patients into group 1 (purulence in right lower quadrant only) and group 2 (contamination in two or more quadrants) was done. Following exclusion of 19 patients with incomplete data, 115 patients were left for analysis; of these, 69 (60%) were in group 2. Observations revealed a longer stay and more postoperative complications, particularly procedure-related events, among patients in group 2. Seemingly, this simple classification of perforated appendicitis is relevant for a good differentiation of clinical outcomes, especially for iatrogenic morbidity, making it helpful for operative preparation and outcomes research.
