Highlights
Acute appendicitis and appendiceal diverticulosis can present with pain in the right lower quadrant, which makes differential diagnosis difficult.
Preoperative imaging tests do not contribute to the definitive diagnosis because the diagnosis is mainly determined by the histological study.
The perforation rate of appendicitis diverticulitis is four times higher than the perforation rate of acute appendicitis.
In addition, there may be a risk of developing peritoneal pseudomyxoma in some patients with appendiceal diverticulosis.
Laparoscopic appendectomy is considered a safe and appropriate treatment for simple appendiceal diverticulitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
