Evaluation and Management of Abdominal Stab Wounds

An abdominal stab wound can involve the peritoneal cavity, retroperitoneum, or diaphragm. The learning activity examines how patient physiology, examination reliability, and wound location influence the choice between urgent exploration, diagnostic evaluation, and serial observation.

Initial assessment and patient physiology

The activity begins with the primary survey, hemodynamic assessment, and examination for findings that may require operative intervention. Wound documentation and associated injuries matter, but additional diagnostic workup must be considered in the context of the patient’s stability. The pathway contrasts patients who need urgent operative care with those who can undergo further assessment.

Examination reliability and wound location

Selective evaluation depends on whether the patient can participate in a reliable abdominal examination. Altered mental status, intoxication, distracting injuries, sedation, or neurological injury can limit that assessment. The algorithm explores how this changes the use of diagnostic studies and serial reassessment.

Anterior abdominal, flank/back, and thoracoabdominal wounds raise different diagnostic questions. Learners review the roles of local wound exploration, contrast-enhanced CT, and laparoscopy, including the potential for diaphragmatic or retroperitoneal injury.

Observation, reassessment, and disposition

The activity follows serial examinations and reassessment for evolving peritonitis, instability, or evidence of bleeding. It also considers the transition from an unreliable to a reliable examination and the importance of follow-up and return precautions when planning discharge. Learners work through these decisions within the signed-in algorithm.

Learning focus

Distinguish physiology-driven operative assessment from selective diagnostic evaluation.
Assess whether a patient can undergo reliable serial abdominal examinations.
Compare diagnostic approaches by wound location and suspected injury.
Recognize the role of reassessment in observation and disposition planning.
