The dilemma of stump appendicitis - A case report and literature review.

INTRODUCTION

Stump appendicitis is one of the rare delayed complications post appendectomy with a reported incidence of 1 in 50,000 cases. Stump appendicitis can present as a diagnostic dilemma if the treating clinician is unfamiliar with this rare clinical entity. A PubMed search was conducted to identify cases of stump appendicitis following appendectomy. Sixty one cases of SA that were reported in English medical literature were analyzed.

PRESENTATION OF CASE: We report a case of stump appendicitis (SA) with a systematic review and challenges encountered during the management.

DISCUSSION: The interval from original appendectomy to stump appendicitis ranged from 4 days to 50 years. SA followed appendectomy in 58% of open and 31.6% of laparoscopic procedures. SA was frequently misdiagnosed as constipation, gastroenteritis or right sided diverticulitis, therefore leading to a significant delay to surgery. Computerized Tomography diagnosed SA in 56.3% of cases. Perforation with gangrene of the stump occurred in 60%.

CONCLUSION

Stump appendicitis can represent a diagnostic dilemma if the treating physician is unfamiliar with this uncommon clinical entity. Radiological imaging is required to aid diagnosis and a completion appendectomy is the modality of treatment.
