    Journal: Hepatogastroenterology; 2010; 57(104):1423-9. PubMed ID: 21443097.
    Abstract:
    BACKGROUND/AIMS: To demonstrate how EUS tumor staging has a practical effect on deciding the treatment strategy for esophageal carcinoma, we retrospectively evaluated the clinical impact of thin-probe EUS staging. METHODOLOGY: The results of EUS performed 54 times were classified according to clinical impact into three grades (none, supportive, and important) and analyzed to assess their impact on the treatment strategy on individual occasions. RESULTS: EUS was important in determining treatment strategy for 23 of 39 lesions (59.0%) in the EUS-superficial group and supportive for 16 lesions (41.0%). The clinical impact of EUS for 15 lesions in the EUS-deep group was graded important for 8 lesions (53.3%), supportive for 6 lesions (40.0%) and none for one lesion (6.7%). CONCLUSIONS: Thin-probe EUS is expected to have some clinical impact on the determination of treatment strategies for squamous cell carcinoma of the esophagus.
