Bilan d’extension locorégionale des cancers gastriques par écho-endoscopie (EE)

Preoperative loco regional Staging of Gastric Cancer by Endoscopic Ultrasonography

  • Published:
Acta Endoscopica

Résumé

Cette étude prospective a été menée chez 165 patients consécutifs qui ont bénéficié d’une échoendoscopie (EE) pré-opératoire avant intervention pour cancer gastrique.

Le pourcentage total de précision diagnostique concernant l’extension pariétale était de 78 %.

La sensibilité et la spécificité de l’EE dans le bilan d’extension ganglionnaire régionale était de 82 et 84 % respectivement.

L’envahissement microscopique en profondeur ou les remaniements inflammatoires étaient les deux causes les plus fréquentes de mauvaise classification TNM. Une sténose tumorale était le facteur limitant de l’EE dans 14 % des cas.

Summary

165 consecutive patients with gastric carcinoma who underwent surgery were prospectively evaluated with endoscopic ultrasonography (EUS) before operation.

Endosonographic findings were categorized according to the TNM classification and compared with the histology of the resected specimen.

The overall accuracy rate of EUS in the assessment of the depth of tumor infiltration was 78 %. The sensitivity and specificity of EUS in the detection of regional involved lymph nodes were 82 % and 84 % respectively.

Microscopic tumor invasion and indistinguishable imflammatory changes where the most frequent causes of misinterpretation by EUS.

Tumors tenosis was a clear limitation for endosonography in 14 % of the cases.
