Background: Acute appendicitis (AA) is one of the most common acute surgical conditions in children. Coagulation tests (CoTs) are usually utilized in preoperative assessment to rule out hemorrhagic risks. Our study aimed to evaluate the role of CoTs as predictors for the severity of AA. Methods: In a retrospective study, we compared the blood tests of two cohorts of pediatric patients with AA (group A and B) evaluated in the Emergency Department of a Pediatric Tertiary care hospital between January 2017 and January 2020. Children in Group A underwent appendectomies while those in Group B were treated with conservative management per hospital protocol. Group A was then subdivided into non-complicated (NCA) and complicated appendicitis (CA), and the CoTs were compared between the two subgroups. Results: Group A consisted of 198 patients and Group B of 150 patients. Blood tests, including CoTs and inflammatory markers, were compared between the 2 groups. We found a statistically significant difference in PT ratio mean value between Group A and B, suggesting that those who underwent appendicectomies had higher PT ratio values. From a pathophysiological point of view, we speculated that the variation of PT ratio in AA might be secondary to a vitamin K absorption deficit due to enteric inflammation. Conclusions: Our study underlined that a longer PT ratio could be helpful to distinguish CA from NCA. Further investigations may lead to the role of the PT ratio in the choice between conservative and surgical management.

Abstract
Background: Acute appendicitis (AA) is one of the most common acute surgical conditions in children. Coagulation tests (CoTs) are usually utilized in preoperative assessment to rule out hemorrhagic risks. Our study aimed to evaluate the role of CoTs as predictors for the severity of AA. Methods: In a retrospective study, we compared the blood tests of two cohorts of pediatric patients with AA (group A and B) evaluated in the Emergency Department of a Pediatric Tertiary care hospital between January 2017 and January 2020. Children in Group A underwent appendectomies while those in Group B were treated with conservative management per hospital protocol. Group A was then subdivided into non-complicated (NCA) and complicated appendicitis (CA), and the CoTs were compared between the two subgroups. Results: Group A consisted of 198 patients and Group B of 150 patients. Blood tests, including CoTs and inflammatory markers, were compared between the 2 groups. We found a statistically significant difference in PT ratio mean value between Group A and B, suggesting that those who underwent appendicectomies had higher PT ratio values. From a pathophysiological point of view, we speculated that the variation of PT ratio in AA might be secondary to a vitamin K absorption deficit due to enteric inflammation. Conclusions: Our study underlined that a longer PT ratio could be helpful to distinguish CA from NCA. Further investigations may lead to the role of the PT ratio in the choice between conservative and surgical management.
