Summary
Pathologic examination of explanted vaginal mesh is appropriate. Incomplete documentation of clinical history and mesh material hinders accurate gross examination and necessitates further histologic study.
Area of Science:
- Urogynecology
- Pathology
- Medical Device Analysis
Background:
- Vaginal mesh use has raised safety concerns, necessitating thorough evaluation of explanted devices.
- Pathologic examination plays a crucial role in understanding mesh complications and improving patient care.
Purpose of the Study:
- To review institutional experience with analytic processes and pathologic findings of explanted vaginal mesh.
- To identify areas for improvement in documentation and research related to vaginal mesh explants.
Main Methods:
- Retrospective review of gross and microscopic pathology reports and slides of explanted mesh specimens (January 2010-February 2012).
- Abstraction of clinical history, specimen details, and examination type from pathology records.
Main Results:
- 102 cases reviewed; 97% of explants contained tissue.
- Clinical history was frequently incomplete (24.5%), often leading to increased histopathologic examination.
- Mesh material (polypropylene) was rarely documented, and gross descriptions were sometimes inaccurate (e.g., "metallic").
Conclusions:
- Both gross and histopathologic examination are suitable for mesh explants.
- Incomplete documentation of clinical history and mesh material is common.
- Improved documentation is recommended to enhance pathologic examination and facilitate future research on mesh complications.
