To the Editor We thank Mällinen et al1 for their study questioning the need for interval appendectomy in patients presenting with periappendicular abscess following successful initial nonoperative treatment. The study was terminated at a much earlier stage than anticipated owing to an interim analysis that reported a high incidence rate of appendiceal tumors found, which meant it was no longer ethically viable to have a follow-up group. We therefore urge caution in using the data collected in drawing any form of conclusion. The topic remains controversial,2,3 and we therefore wish to encourage more studies to be conducted and make 2 points about this study.
