Do patients with penetrating abdominal stab wounds require laparotomy?

Area of Science:

• Trauma Surgery
• Surgical Management
• Emergency Medicine

Background:

• Optimal management of hemodynamically stable asymptomatic patients with anterior abdominal stab wounds (AASWs) is controversial.
• Current evaluation strategies include local wound exploration (LWE), diagnostic peritoneal lavage (DPL), serial clinical assessment (SCAs), and computed tomography (CT) imaging.
• Deciding on operative intervention for penetrating abdominal stab wounds, particularly with visceral evisceration, presents a continuing challenge.

Purpose of the Study:

• To evaluate the outcomes of emergency laparotomy in patients with penetrating anterior fascia or visceral evisceration.
• To inform improved management strategies for penetrating abdominal stab wounds.
• To assess the efficacy of emergency laparotomy as a primary intervention.

Main Methods:

• Retrospective cross-sectional study of 150 patients with anterior abdominal penetrating trauma from October 2000 to October 2010.
• Exclusion criteria included blunt trauma, age under 14, lateral stab wounds, and hemodynamic instability.
• Data collected included demographics, trauma mechanism, and results of local wound exploration (LWE) and laparotomy; analyzed using PASW v.20.

Main Results:

• Of 150 patients, 63 underwent immediate laparotomy due to shock, evisceration, or significant NG tube aspiration.
• In 87 cases with visceral evisceration, 78% had organ injury.
• Among 58 patients with LWE-detected anterior fascia penetration, 18% had visceral injuries upon laparotomy; 33.3% of these had no fascial penetration on LWE and were managed non-operatively.

Conclusions:

• 82% of laparotomies for penetrated anterior abdominal fascia without visceral evisceration and no peritoneal signs were negative, suggesting a need for further evaluation in these cases.
• Visceral evisceration remains a strong indication for exploratory laparotomy due to a high incidence of associated organ damage.
• Refined diagnostic approaches can potentially reduce unnecessary laparotomies in selected AASW patients.
