In brief
Meta-analysis of 15 trials comparing immediate appendectomy versus conservative treatment for complicated appendicitis in children found that conservative management reduced overall complications and wound infections, while immediate surgery shortened hospital stay. Neither approach affected rates of intraabdominal abscess or postoperative ileus, highlighting the need for randomized trials to establish optimal management.

Purpose
This study carried out a meta-analysis to compare immediate surgery (IS) with conservative treatment (CT) of complicated acute appendicitis (CAA) in children.
Methods
Systematic literature research was performed for relevant studies published from 1969 to date. Trials of IS compared with CT were included. Outcomes of interest were postoperative morbidity and length of hospital stay (LOS).
Results
Fifteen trials were studied (1.243 patients). CT achieved better rates of any complication type (odds ratio [OR] 0.22, [95% confidence interval (CI): 0.14, 0.38], p = 0.001) and wound infection (OR: 0.40 [95% CI: 0.17, 0.96], p = 0.041). Neither intraabdominal abscess (OR: 1.03 [95% CI: 0.31, 3.37], p = 0.958) nor postoperative ileus (OR: 0.29 [95% CI: 0.06, 1.44], p = 0.130) was affected by the treatment option. The polled difference in LOS showed a trend for shorter LOS in the IS group (standard mean difference [SMD]: 0.25 [95% CI: 0.07, −0.43], p = 0.007).
Conclusions
IS was associated with shorter LOS, while overall complication rates and wound infection declined significantly with CT. The development of intraabdominal abscess and postoperative ileus was not affected by the treatment of choice. The heterogeneity of most studies depicts the need for randomized controlled trials (RCTs) to discover safe management of CAA in children.
