Abstract :Background: Acute appendicitis is the most commonly encountered and operated group among general surgery emergency patients. Various scoring and algorithms are used in diagnosis and treatment. This study aimed to compare the Laparoscopic Appendicitis (LAPP) score, which is used to reduce negative appendectomy, according to the pathology and preoperative computed tomography results and investigate its correlation with other clinical scoring systems. Methods: Patients who underwent appendectomy in our clinic between June 2020 and March 2021 were retrospectively reviewed. The obtained LAPP scores were compared with the preoperative imaging results, Alvarado score, appendicitis inflammatory response (AIR) score, and pathology results. Results : The study included a total of 109 patients, of whom 22 (20.18%) had a pathology result that was not consistent with appendicitis. The LAPP score was determined as 1.41 for this 22 patients who underwent negative appendectomy (p<0.001), 2.45 for 74 patients with suppurative appendicitis (p<0.001), and 3.54 for 13 patients with gangrenous or perforated appendicitis (p<0.001). Conclusions: The purpose of the LAPP score is to reduce the rate of negative appendectomy. Appendectomy is also performed in some patients who may have spontaneous resolution if they present to the hospital in the early period. We also consider that the frequency of familial Mediterranean fever in Turkey may be another reason for the high rate of negative appendectomy. In addition, the correlation of high Alvarado and AIR scores with a high LAPP score indicates that it is more reliable in the diagnosis of complicated appendicitis.
