TLDR
In routine cases, histopathological examination of disc specimens is not justified, and the decision to send specimens for pathological examination should be based on the surgeon's judgment.
Abstract
But: Dans les hopitaux nord- americains, les specimens de disques intervertebraux sont examines de routine en anatomopathologie. Cependant, des etudes recentes ont remis en question la pertinence de cette pratique dans les cas ou l'indication chirurgicale est une pathologie benigne comme une maladie discale degenerative. Cette etude porte sur le ratio cout-benefice de cette pratique. Methodes : Nous avons effectue une analyse cout-benefice de l'examen anatomopathologique fait de routine entre 1996 et 2004 sur 1775 specimens provenant de discectomies faites de routine (indications chirurgicales non neoplasiques et non infectieuses) et 70 specimens provenant de discectomies chez des patients chez qui on soupconnait une neoplasie ou une infection. La revue des dossiers a permis de determiner si les constatations anatomopathologiques etaient significatives au point de vue clinique, c'est-a-dire si elles avaient influence le traitement du patient. Nous avons calcule le cout total. Une revue de la litterature nous a permis de comparer nos resultats a ceux d'autres chercheurs. Resultats : Nous avons decouvert 4 comptes rendus anatomopathologiques inattendus parmi les 1775 specimens provenant des cas de routine, dont un etait significatif au point de vue clinique, a un cout de 42 165,25$par trouvaille anatomopathologique et de 168 625 $ par trouvaille anatomopathologique significative au point de vue clinique. Pour les chirurgies qui n'etaient pas faites de routine, le cout par constatation anatomopathologique anormale etait de 116,67$. Conclusions : Quand il s'agit de cas de routine, l'examen anatomopathologique des specimens de disques n'est pas justifie. La decision de demander un examen anatomopathologique de ces specimens chirurgicaux devrait etre basee sur le jugement du chirurgien.

Histological analysis of surgical lumbar intervertebral disc tissue provides evidence for an association between disc degeneration and increased body mass index

TL;DR: This study demonstrated that histological disc alterations in surgical specimens can be graded in a reliable manner based on a quantitative histologic degeneration score (HDS), and increased BMI was identified as a positive risk factor for the development of symptomatic, clinically significant disc degeneration.

Histologic Examinations of Arthroplasty Specimens are not Cost-effective: A Retrospective Cohort Study

TL;DR: Routine histologic examinations of routine operative specimens during elective primary arthroplasties increase medical cost but rarely alter patient management and are not cost-effective.

Routine Examination of Pathology Specimens Following Knee Arthroscopy: A Cost-Effectiveness Analysis.

TL;DR: Routine pathological examination of surgical specimens from patients undergoing knee arthroscopy had limited cost-effectiveness because of the low prevalence of findings that altered patient management and gross and histological examination should be done at the discretion of the orthopaedic surgeon rather than being mandatory.

Cost-benefit analysis of routine pathology examination in primary shoulder arthroplasty

TL;DR: This study showed limited clinical utility in routinely sending specimens from primary shoulder arthroplasty cases for pathology examination, and calculation using a traditional life-year value of $50,000 showed that the standard for cost-effectiveness is not met.

Costs Versus Benefits of Routine Histopathological Examination in Total Ankle Replacement.

TL;DR: The costs of routine histopathological examination of tissue specimens removed during total ankle replacement outweigh clinical benefits, and such examination should be left to the discretion of the operating surgeon.

Frequency of unexpected and important histopathological findings in routine intervertebral disc surgery

TL;DR: The results of this retrospective study suggest that routine histopathological examination of specimens obtained during intervertebral disc procedures is both justified and cost effective.

Incidence of unusual and clinically significant histopathological findings in routine discectomy.

TL;DR: Routine histopathological examination of disc specimens is not justified and the decision to send specimens for pathological examination should be determined on a case-by-case basis after consideration of the clinical presentation, results of laboratory and imaging studies, and intraoperative findings.
