Abstract:

Aim: Appendix tumors are a rare tumor of the gastrointestinal system. One-third of epithelial tumors of the appendix are mucinous neoplasms. In this study, we aim to provide literature with our clinical approach and treatment results for appendiks mucinous neoplasia patients. Material and Methods: The files of 1028 patients who underwent appendectomy between January 2012 and January 2022 were examined retrospectively. Patients with a histopathological diagnosis of appendiceal mucinous neoplasia were included in the study. The patients' age and gender data, presenting symptoms, tumor marker values (CEA, CA125, CA19-9), computed tomography findings, surgical branch performing the surgery, applied surgical methods, frozen data, histopathological diagnoses and survival information were recorded. Results: There were 35 (3.4%) patients whose histopathological diagnosis was mucinous neoplasm. Twenty-eight (80%) of our patients were female, 7 (20%) were male, and the mean age was 57.5 ± 11.68 years. There were 21 (60%) patients who presented with abdominal pain, 9 (25.7%) patients with bloating and palpable mass, and 5 (14.2%) patients without complaints. 7 (20%) of the patients had elevated CA125. Computed tomography revealed acute appendicitis in 9 (25.7%) patients. Of the patients, 28 (80%) underwent appendectomy only, 5 (14.2%) right hemicolectomy, and 2 patients underwent cytoreduction + hyperthermic intraperitoneal chemotherapy after appendectomy. Our mortality number was four (11.4%). Conclusion: In mass lesions of pelvic origin, appendiceal mucinous neoplasia should be kept in mind due to anatomical proximity, patients should be evaluated multidisciplinary and treatment should be shaped by frozen examinations to be performed at the time of surgery, if necessary.
