Mucocoele of the appendiceal stump

Case contributed by Chris O'Donnell
Diagnosis almost certain

Presentation

Appendectomy 6 weeks ago, now increasing RIF pain

Patient Data

Age: 45
Gender: Male

Fluid filled distension of the appendiceal stump with a line of surgical staples at the tip of the stump. Minimal surrounding inflammatory change.

Case Discussion

The appendiceal stump is usually buried or inverted into the cecum at surgery to prevent complications including leak, "stumpitis" and mucocoele. In this case a line of surgical staples has been used across the proximal appendix without inversion leaving a small segment of stump allowing a mucocoele to develop.
