BACKGROUND: Antenatally detected asymptomatic congenital cystic lung lesions may be managed conservatively or by surgical resection. We undertook a systematic review and meta-analysis to quantify the risks of elective surgery, emergency surgery, and observation. METHODS: All series published between 1996 and 2008, where the postnatal management of congenital cystic lung lesions was described, were reviewed. A meta-analysis was performed to determine whether elective or emergency surgery was associated with a higher risk of adverse outcomes. RESULTS: There were 41 reports describing 1070 patients (of whom 79% were antenatally detected). Five hundred five neonates survived without surgery into infancy, of whom only 16 (3.2%) became symptomatic. For all ages, elective surgery was associated with significantly less complications than emergency surgery. The risk ratio was 2.8 (95% confidence interval, 1.4-5.5; P < .005) when comparing complications after elective surgery with emergency surgery. CONCLUSIONS: The risk of asymptomatic cases developing symptoms is small. However, elective surgery is associated with a better outcome than emergency surgery. If elective surgery is undertaken, it should be performed before 10 months. Although no prognostic indicators have so far been identified in the literature, a conservative approach may be appropriate for small lesions.
