Özet

Objective: We reported the demographic, clinical, radiologic, preoperative and postoperative characteristics and outcomes on patients of appendix mucocele that presented with or operated for acute appendicitis or acute abdomen. Methods:A retrospective study. Patients who were presented or operated for acute appendicitis or acute abdomen and had an operative histopathological diagnosis as appendix mucocele (simple mucocele, mucinous cystadenoma, mucinous cystadenocarcinoma) were included. Demographic, clinical, radiologic, preoperative and postoperative data of eligible cases were evaluated. Results: From January 2003 to February 2010, a total of 2120 patients with the pre-operative diagnosis of acute appendicitis were treated in our center, and nine (0.42%) patients were diagnosed to have mucocele of the appendix. Seven patients (78%) were female. Average age of the patients was 59.5 (range=25-74). Major complaint was right lower quadrant pain in eight (89%) patients. In preoperative ultrasonographic examination of the patients, appendiceal cystic masses (mucocele) were diagnosed in four (44.5%) patients. In histopathologic examination, the number of patients diagnosed to have simple mucocele was two (22%), mucinous cystadenoma was four (45%), and mucinous cystadenocarcinoma was three (33%). No postoperative morbidity or mortality was noted. Conclusion: Appendix mucocele is a rare disease and it is usually diagnosed histopathologicaly in appendectomy specimens. When a cystic mass in appendix is seen during operation, appendiceal mucocele should be kept in mind to avoid iatrogenic perforation causing pseudomyxoma peritonei and possible concomitant malignancies should be searched.
