A Single Institute Review of 4,428 Consecutive Appendiceal Resections: Incidence of Suspected and Incidental Pathology.

AIMS: To determine the incidence of non-appendicitis pathology of the appendix in an Irish context.

METHODS

A single institute review of 4,428 consecutive appendiceal resections was conducted independently by two researchers. Clinical, radiological, intra-operative, and histological reports were reviewed.

RESULTS

A total of four-thousand four-hundred and twenty-eight (4,428) appendicectomies including right hemicolectomies, subtotal colectomies, panproctocolectomies, ileocolic resections, and en-bloc resections were performed during the study period. Incidental malignancies occur in less than one per cent (<1%) of appendiceal resections. The mean age of incidental malignancies was 54.75 (range 11 - 79 years), and the mean age for non-incidental appendiceal malignancies was 62 (range 42 - 85 years).

CONCLUSION

A wide array of neoplastic and inflammatory conditions' incidence in the Irish context is described for the first time.
