摘要
Objective To evaluate the efficacy of ultrasonography for the diagnosis of cervical lymph node metastasis in esophageal carcinoma. Summary Background Data Ultrasound (US) examination is useful for diagnosing lymph node metastasis. However, few reports have examined its role in the decision to perform cervical lymph node dissection in esophageal carcinoma. Methods Ultrasound examination was performed to evaluate cervical lymph node metastasis in 519 patients with esophageal carcinoma. The patients were divided into 5 groups according to treatment received: group 1, 153 patients who underwent curative resection of primary tumor by right thoracotomy and complete bilateral cervical lymphadenectomy; group 2, 112 patients who underwent curative resection of primary tumor by right thoracotomy but without cervical lymphadenectomy; group 3, 78 patients who underwent esophagectomy by left thoracotomy or blunt dissection with or without removal of cervical lymph nodes; group 4, 76 patients with palliative resection without cervical lymphadenectamy; and group 5, 100 patients without any surgical treatment. US diagnosis was compared with histologic findings Dr cervical lymph node recurrence. Results Lymph node metastasis was detected in 30.8% of patients (160/519). The sensitivity, specificity, and accuracy of US diagnosis in group 1 were 74.5%, 94.1%, and 87.6%, respectively. Cervical lymph node recurrence was seen in 7 patients (4.6%) in group 1, in 4 patients (3.6%) in group 2, and 3 patients (3.8% in group 3. Although the incidence of cervical lymph node metastasis as determined by US examination was high in groups 4 and 5, almost none of the patients died of cervical lymph node metastasis. Conclusions Ultrasound examination plays a useful role in the decision to perform cervical lymph node dissection in patients with esophageal carcinoma, particularly in those with potentially curative dissection.
