RESUMO
AIM: A systematic review of the literature was undertaken to examine reported cases of stump appendicitis (SA) to determine the relationship between SA and the original operative strategy (open vs laparoscopic), and to evaluate the clinical features and diagnosis. METHOD: A Pub-med search was conducted to identify cases of appendicitis of a residual stump following appendicectomy. Two original cases of SA following laparoscopic appendicectomy treated in our own hospitals are also included in the analysis. Sixty cases of SA reported in the English medical literature were analysed. RESULTS: The interval from the original appendicectomy ranged from 4 days to 50 years. SA followed appendicectomy in 58% of open and 31.6% of laparoscopic procedures. SA was frequently misdiagnosed as constipation or gastroenteritis, with a significant delay to surgery. Computerized tomography diagnosed SA in 46.6% of cases. Perforation with gangrene of the stump occurred in 40%. CONCLUSION: Stump appendicitis is rare. It may complicate open or laparoscopic appendicectomy. A high level of suspicion should be maintained in any patient with right sided abdominal pain and a history of prior appendicectomy.
