ABSTRACT AIM: This study aims to assist the surgical treatment plan by increasing the rate of correct preoperative diagnoses through comparing the clinical, radiological, and laboratory findings of appendiceal mucocele (AM) and acute appendicitis (AA) before surgery. MATERIALS AND METHODS: The study included 63 patients with a histopathologic diagnosis of AM and AA among 4867 patients who underwent appendectomy with the diagnosis of acute appendicitis in the general surgery clinic between 2009 and 2020. The patients were separated into two groups: those with AM (21 patients) and those with AA (42 patients). Age, gender, physical examination (PE), Alvarado appendicitis score, ultrasonography (USG), computed tomography (CT), laboratory, preoperative diagnosis, intraoperative diagnosis, and pathological diagnosis results of both groups were compared. RESULTS: PE, abdominal pain, nausea, vomiting, fever symptoms, and Alvarado score were found to be significant between the two groups (p<0.05). In addition, WBC, NE, LYM %, and CRP were found to be high in group 2 (p<0.05), while there was no difference in radiological diagnosis (USG/CT) between the two groups (p<0.05). However, the appendix diameter was larger in group 1 (p<0.05). Patients with AM in 80% preoperatively, and 52% intraoperatively were operated on with a provisional diagnosis of AA. The second surgery was performed in Group 1 with a rate of 9.5% (2/21). CONCLUSION: In our study, patients with AM who underwent surgery with a diagnosis of AA were found to differ in radiological, clinical, and laboratory findings from patients with AA.
