Risk of appendiceal neoplasm in periappendicular abscess in patients treated with interval appendectomy vs follow-up with magnetic resonance imaging. 1-year outcomes of the Peri–appendicitis Acuta randomized clinical trial. JAMA Surg 2019; 154: 200-207.

Published: 2nd August 2019

Authors: Mällinen J, Rautio T, Grönroos J, Rantanen T, Nordström P, Savolainen H et al.

Conclusion

The trial was terminated after 60 patients were included. Twelve patients had tumours of the appendix after surgery, suggesting interval appendicectomy should be routine.
