OBJECTIVE The aim of this study is to compare the effectiveness of initial non-operative treatment strategy (reserving appendectomy for those not responding or with recurrent disease) with immediate appendectomy in children from 7 to 17 years old, inclusive, with acute simple appendicitis in terms of complications, health-related QOL and costs. Main research question: What is the difference in proportion of patients experiencing complications within 1 year between both strategies in children from 7 to 17 years old, inclusive, with acute simple appendicitis?
