“…In patients with non‐small cell lung cancer, IU was used to guide the dissection of mediastinal lymph nodes with a higher number of nodal stations yielded, and skip nodal metastasis were found in 24% of patients without N1 nodal involvement. Ryo reported that IU was a highly sensitive technique for diagnosing lymph nodes metastases in patients with ovarian and uterine corpus malignancy. Our pilot study revealed the superiority of IU for evaluating RLN lymph nodes in patients with ESCC; the sensitivity and NPV of IU were 100%.…”

“…IU is free from the interference of air‐containing organs such as the bowel, lungs, and trachea, and yields high‐quality images. In addition to detecting small lesions, surgeons have applied this technique to identify locoregional lymph nodes in several malignancies . This pilot study was performed to explore the safety, accuracy, and characteristics of IU for identifying RLN lymph nodes in patients with thoracic esophageal cancer.…”

The rate of vocal cord palsy following resection for esophageal carcinoma has increased due to lymphadenectomy around the recurrent laryngeal nerves (RLN). The aim of this pilot study was to assess the ability of intraoperative ultrasonography to detect thoracic RLN node metastases in patients with esophageal cancer. Intraoperative ultrasonography was performed during esophagectomy to assess whether RLN lymph nodes were metastatic in 10 patients with esophageal squamous cell cancer. All patients underwent RLN lymphadenectomy, and the nodes were assessed for metastasis. Three patients had pathological RLN lymph node metastases, of which one had right RLN node metastasis, and three had left RLN node metastases. For detecting right RLN lymph node metastasis, the sensitivity, specificity, and positive and negative predictive values of intraoperative ultrasonography were 100%, 33.3%, 14.3%, and 100%, respectively. For the detection of left RLN lymph node, these values were 100%, 85.7%, 75%, and 100%, respectively. This study suggests that intraoperative ultrasonography is feasible and safe to detect RLN lymph node metastases for patients with esophageal cancer. Further study will be performed to evaluate the validity and utility of this diagnostic technique.

Objective: To evaluate the usefulness of intraoperative ultrasonography (IU) for para-aortic nodes to identify women who do not require pelvic and paraaortic lymphadenectomy in ovarian carcinoma. Methods: Computed tomography (CT) was used for assessing both pelvic and para-aortic lymph nodes, and IU only for para-aortic nodes in 87 women with ovarian carcinoma. All women underwent surgery with routine systematic pelvic and para-aortic lymphadenectomy. We assumed that no lymphadenectomy had been performed when no enlarged node was detected by either CT or IU or when the woman was in T1 stage. Under these assumptions, the numbers of women who would have had missed metastases and who could have avoided lymphadenectomy were counted. These figures were recounted on the combination of T stage and IU. Results: A total of 22 women had pathological node metastases. The numbers of women with missed metastases on the basis of CT, IU, and T stage were 12, 2, 5, and these who could have avoided lymphadenectomy were 72, 39, and 49, respectively. There were more women avoiding lymphadenectomy by CT than IU and T stage; however, more women with missed node metastases. Both numbers were not significantly different between IU and T stage. On the combination of T stage and IU, 29 of 49 women in T1 stage could have avoided lymphadenectomy without missed metastases. Conclusions: IU for the para-aortic node is a useful method for identifying women who do not require lymphadenectomy for T1 stage ovarian carcinoma.

“…13,14 Intraoperative ultrasonography had superior negative predictive value and sensitivity for para-aortic node metastases compared with palpation during surgery and preoperative CT. In addition, IU seemed to be a promising diagnostic tool for avoiding unnecessary para-aortic lymphadenectomy in women with gynecological malignancies.…”
