An asymptomatic detachment of the appendix evolved to giant abscess and complete colliquative necrosis: pivotal role of computed tomography in patient management.

BJR Case Rep 2021 Apr 11;7(2):20200125. Epub 2020 Dec 11.

Department of Radiology, Azienda Ospedaliero-Universitaria di Bologna, Bologna, Italy.

Acute appendicitis (AA) is one of the most common causes of acute abdominal pain and it generally affects young males in the second or third decade of their life. Due to its often insidious presentations, the diagnosis is challenging and, if delayed, can lead to life-threatening complications. This report describes a rare case of an almost asymptomatic complicated appendicitis caused by an appendicolith followed by spontaneous detachment of the vermiform appendix and its complete colliquative necrosis with abscess formation.

Appendiceal Goblet Cell Adenocarcinoma Case Report and Review of the Literature.

Cureus 2021 Feb 23;13(2):e13511. Epub 2021 Feb 23.

Surgery, Beaumont Health, Dearborn, USA.

Acute appendicitis is a common presentation to the emergency department. The common pathogenesis thereof relates to obstruction of the appendiceal lumen by an appendicolith, which leads to an increase in intraluminal and intramural pressure. This is followed by distension of the appendix, subsequent small vessel occlusion and lymphatic stasis, and appendiceal wall ischemia and necrosis, eventually leading to rupture if not treated.

However, the type of operation (open appendectomy) and average duration of stay are not consistent with current American practice and therefore their conclusions do not apply to modern American surgeons.
