Stump appendicitis refers to inflammation of the residual appendiceal tissue post appendectomy.
Partial removal of the appendix with a residual stump allows for a chance of recurrent appendicitis. Chances of a partial removal are found to be higher in cases where there is a wrong identification of the cecal appendiceal junction and a retrocaecal or subserosal appendix.
CT is more specific than ultrasound for an accurate diagnosis because it excludes other clinical mimics. The findings may be similar to those seen in acute appendicitis including pericaecal inflammatory change, abscess formation, fluid in the right paracolic gutter, caecal wall thickening and an ileocaecal mass.
Treatment and prognosis
The treatment of choice is either open or laparoscopic completion of the appendectomy.

The appendix can be affected by numerous inflammatory, infectious and neoplastic conditions:
- appendiceal mucocele
- appendiceal intussusception
neoplasms of the appendix
- appendiceal epithelial neoplasms
- Goblet cell carcinoid of the appendix
- appendiceal neuroendocrine tumours
- appendiceal lymphoma
