To evaluate the diagnostic accuracy of various modalities, including physical examination, ultrasound, CT-scan, MRI, and per-operative diagnosis, used to identify incisional hernia (IH) after open abdominal surgery and after IH repair surgery.
Key Findings:
Incisional hernia prevalence rates vary between 10% and 32%, influenced by factors such as age and obesity.
Diagnostic modalities include physical examination, ultrasound, CT-scan, MRI, and per-operative diagnosis, each with varying effectiveness.
Imaging modalities are recommended for reliable IH diagnosis, but their effectiveness is inconsistent across studies.
Inconsistent definitions of IH across studies affect diagnostic outcomes and comparability.
Interpretation:
Different diagnostic modalities, definitions, and protocols may significantly influence the identification rates of incisional hernias, impacting clinical decision-making.
Limitations:
Variability in definitions of incisional hernia across studies may lead to inconsistent results.
Potential biases in study selection and data extraction could affect the reliability of findings.
Limited evidence on the reliability of different diagnostic modalities hampers definitive conclusions.
Conclusion:
The systematic review highlights the urgent need for standardized definitions and protocols in IH diagnosis to improve detection rates and enhance the comparability of research findings.
