Damage control laparotomy trial: design, rationale and implementation of a randomized controlled trial

Area of Science:

• Trauma Surgery
• Surgical Critical Care
• Abdominal Trauma Management

Background:

• Damage control laparotomy (DCL) is a critical intervention for severely injured patients to prevent physiological collapse.
• Current indications for DCL are broad, lacking high-quality evidence to guide optimal surgical management.
• The study addresses the need for data comparing DCL to definitive abdominal closure in specific patient populations.

Purpose of the Study:

• To determine the effect of definitive laparotomy versus DCL on major abdominal complications and mortality in patients with indications for DCL.
• To provide evidence to guide clinical decision-making regarding abdominal closure strategies in emergent laparotomy.

Main Methods:

• Pragmatic, parallel-group, randomized controlled pilot trial.
• Patients eligible for DCL (excluding specific complex cases) were randomized intraoperatively to DCL (control) or definitive fascial closure (intervention).
• Primary outcome: composite of major abdominal complication (fascial dehiscence, surgical site infection, enteric failure, re-operation) or death within 30 days.

Main Results:

• The study is designed to compare outcomes between DCL and definitive laparotomy.
• Results will quantify the incidence of major abdominal complications and death in each group.
• Statistical analysis will employ both frequentist and Bayesian approaches.

Conclusions:

• This trial will elucidate the impact of definitive laparotomy on morbidity and mortality in patients indicated for DCL.
• Findings will inform clinicians about the comparative risks and benefits of these surgical approaches.
• The study aims to enhance the quality of care for critically injured patients undergoing laparotomy.
