[Laparoscopic appendectomy for mucinous cystadenoma of the appendix].

Treatment of acute and chronic appendicitis is still an actual problem. There are some rare courses of the disease besides well-known complications of appendicitis. Mucocele is one of the rarest forms of chronic appendicitis. Mucocele is not accompanied by clinical symptoms and diagnosed accidentally in more than 25% of cases. The most serious complication of mucocele of the appendix is malignization observed in up to 36% of cases. Ultrasound, CT and colonoscopy are the most effective methods of perioperative diagnosis. Unclear symptoms, delayed diagnosis and surgical treatment increase the risk of complications (i.e. cystadenocarcinoma).
