Objectives

Narrative objectives1

To systematically evaluate whether a computed tomography angiography (CTA)-first strategy, compared with immediate operative exploration, is associated with improved clinical outcomes in adult patients with penetrating neck injury presenting with hard signs who are hemodynamically stable and, when necessary, have a secured airway.

Assessment

Primary outcomes

Rate of neck operation comparing a CTA-first strategy with immediate operative exploration. Dichotomous outcomes will be synthesized using pooled risk ratios with 95% confidence intervals.

Key secondary outcomes

1.Incidence of missed injury
2.Incidence of complications
3.Mortality
4.Blood transfusion volume
5.Intensive care unit length of stay
6.Hospital length of stay

Key inclusion criteria

Studies meeting the following criteria will be included: adult patients with penetrating neck injury presenting with hard signs; patients who are hemodynamically stable or stabilized after initial resuscitation; studies evaluating a CTA-first strategy and/or immediate operative exploration; and studies reporting extractable data for at least one prespecified outcome.

Key exclusion criteria

Studies will be excluded if they include only pediatric patients; do not primarily evaluate penetrating neck injury; do not allow extraction of data for patients with hard signs; do not provide evaluable outcomes for CTA-first or immediate operative management; are case reports, reviews, or other non-primary studies; or lack extractable outcome data.

Results

CTA first significantly reduced neck operations versus immediate surgery (RR 0.07,95% CI 0.01-0.50), with no clear increase in complications (RR 0.88,95% CI 0.36-2.16), missed injuries, or mortality.

Other related information

This study is a systematic review and meta-analysis comparing a CTA-first strategy with immediate operative exploration in adult patients with penetrating neck injury presenting with hard signs. Relevant studies will be systematically identified using electronic databases. Study selection and data extraction will be performed independently by multiple reviewers according to prespecified eligibility criteria. The primary outcome is the rate of neck operation. Secondary outcomes include missed injury, complications, mortality, blood transfusion volume, ICU length of stay, and hospital length of stay. For dichotomous outcomes, risk ratios with 95% confidence intervals will be calculated and pooled when appropriate. Risk of bias will be assessed for included studies, and certainty of evidence will be evaluated using the GRADE approach.
