Abstract
There is still much controversy surrounding whether interval appendicectomy is appropriate for adults with an appendiceal mass or abscess. The main debate centres on the recurrence rate, the complication rate of interval appendicectomy, and the potential for underlying malignancy. This review aims to assess current practice and to determine whether it is possible to define “best practice” for the asymptomatic patient who has had an appendiceal mass or abscess treated conservatively. I sent a postal questionnaire to 90 consultant general surgeons requesting information about their practice of interval appendicectomy. I also conducted a literature search confined to studies involving only adult patients. The 77.8% of questionnaires returned revealed that 53% of the surgeons perform routine interval appendicectomy, mainly because of concerns about recurrence. The preference was for open appendicectomy at 6 weeks to 3 months. The literature search revealed a recurrence rate of 10%–25%, with a complication rate of 23%. It was evident that the chances of missing malignancy are low and thorough investigation is better than interval appendicectomy in detecting colonic cancer. The practice of performing interval appendicectomy varies, with just over half of the surgeons surveyed performing this procedure routinely. The literature provides little evidence that interval appendicectomy is routinely indicated and would support the view that it is unnecessary in 75%–90% of cases. However, there is scope for further consideration of the use of laparoscopic interval appendicectomy and a randomised trial is needed to fully evaluate this issue.
