Splenic enlargement and Traube's space: how useful is percussion?

Area of Science:

• Clinical diagnostics
• Physical examination techniques

Background:

• Splenic enlargement (splenomegaly) assessment is crucial in clinical practice.
• Bedside assessment methods are valuable for initial diagnostic evaluation.
• Traube's space percussion is a traditional physical examination technique.

Purpose of the Study:

• To evaluate the diagnostic utility of Traube's space percussion for detecting splenic enlargement.
• To assess the impact of meals and obesity on the accuracy of Traube's space percussion.

Main Methods:

• A case-control study was conducted on inpatients at a tertiary care hospital.
• Patients were selected based on abdominal ultrasonography results for splenic size.
• Traube's space percussion was performed and compared with ultrasonographic findings.

Main Results:

• Traube's space percussion showed a sensitivity of 0.62 and specificity of 0.72.
• Performing the percussion more than two hours post-meal reduced false positives.
• Obesity was associated with an increased rate of false-negative results.

Conclusions:

• Traube's space percussion offers valuable clinical information for splenic enlargement assessment.
• The test's sensitivity and specificity are insufficient to replace further diagnostic investigations.
• Clinical maneuvers like Traube's space percussion should be interpreted considering patient factors such as recent meals and body mass index.
