Background: In recent decades the management of acute appendicitis has evolved significantly. Improved imaging modalities along with clinical scoring algorithms have prompted a demand for lower rates of negative appendicectomy. In particular, non-operative management has become in-vogue within the past number of years. The aim of this study was to assess the variability of management options amongst consultants and trainees.

Methods: Multi-national targeted survey of general surgeons across 38 countries. A structured set of questions was utilised to delineate nuances between management styles of consultants and trainees alike. Opinions on the pathological diagnosis of appendicitis, acceptable negative appendicectomy rates and non-operative treatment of appendicitis (NOTA) were surveyed.

Results: A total of 304 general surgeons responded to this survey, 42% of which were consultants/attendings. Sixty-nine percent advocated that a histologically normal appendix was the most appropriate definition of a negative appendicectomy while 29% felt anything other than inflammation, necrosis, gangrene or perforation was most appropriate. 34% felt that negative appendicetomy rates should be less than 5%. Forty-one percent reported that their own negative appendicectomy rate was <5%. Only 17% reported routinely using NOTA for uncomplicated appendicitis. However, only 22% said they would agree to NOTA if they themselves had uncomplicated appendicitis.

Conclusions: This study represents the largest sampling of management strategies for acute appendicitis. It shows substantial heterogeneity between clinicians regarding what constitutes a negative appendicectomy as well as the appropriateness of non-operative management.
