Histopathological Evaluation of Appendectomies Performed with The Diagnosis of Acute Appendicitis
Abstract
Aim: Acute appendicitis is one of the most common causes of acute abdominal pain in adults. Appendiceal neoplasms account for approximately 0.5% of all gastrointestinal neoplasms. Appendectomy is often performed without any data regarding the tumor, and the tumor emerges as a surprise diagnosis after histopathological examination. Therefore, an effective histopathological evaluation is very important for the course of the disease. The aim of the study is to evaluate patients who underwent surgery with the diagnosis of acute appendicitis and were diagnosed with appendiceal neoplasia.
Material and Methods: Data of 1052 patients who underwent appendectomy between January 2015 and January 2025 were retrospectively analyzed. Demographic, clinical and pathological data of the patients were obtained from the hospital electronic medical record system. The specimens of all patients who underwent appendectomy were examined in the pathology laboratory of our hospital.
Results: Appendiceal tumors were detected in 11 of 1052 patients who underwent surgery with the diagnosis of acute appendicitis (1.05%). Preoperative computed tomography images of the patients did not suggest malignancy. The malign diagnosis was made postoperatively in all 11 patients with histopathological examination.
Conclusion: Appendix tumors are rare and usually detected incidentally. It is very important to perform histopathological examination after appendectomy and to follow up these results. Missing the diagnosis of malignancy may lead to adverse morbidity and mortality outcomes. The results of our study support the importance of histopathological evaluation of the appendix.
