Reconstruction of recurrent laryngeal nerve with involvement by metastatic node in esophageal cancer.

Background: Recurrent laryngeal nerve paralysis represents one of the major complications in esophageal cancer surgery, and patients with esophageal cancer sometimes develop recurrent laryngeal nerve paralysis before treatment. We evaluated recurrent laryngeal nerve reconstruction in patients with lymph node metastasis infiltrating the recurrent laryngeal nerve.

Methods: Five patients with preoperative recurrent laryngeal nerve paralysis as a result of involvement of metastasis were enrolled in the present study.

Thyrotropin-producing pituitary adenoma associated with Graves' disease.

Objectives: The examination of potential associations between Graves' disease and thyrotropin-producing pituitary adenoma (TSHoma) after treatment using octreotide, and of the expression of peroxisome proliferator-activated receptor gamma (PPAR gamma).

Design And Methods: A specimen of resected TSHoma tissue from our case was immunohistochemically examined for expression of somatostatin receptor 2A (SSTR2A) and PPAR gamma. Specimens of thyroid tissue from two cases with Hashimoto's thyroiditis were immunohistochemically examined for expression of SSTR2A.

[Lymph nodes mapping for detection of sentinel nodes in patients with papillary thyroid cancer].

We examined the feasibility of sentinel lymph node biopsy for papillary thyroid cancer. In the dye injection method, 1% of isosulfan blue dye was injected around the tumor of 32 patients intra-operatively, and in the radioisotope (RI) colloid injection method, 99mTc-tin colloid was injected in 23 patients 1 day preoperatively. Lymph node mapping for detection of sentinel nodes was performed after thyroidectomy and central and modified lateral neck lymph node dissections.

Endosonographic detection of mediastinal lymph node metastasis in superficial carcinoma of the esophagus: assessment by type classification and histogram.

Background: Endoscopic ultrasonography (EUS) has been shown to be useful for detecting lymph node metastasis in esophageal cancer. The evaluation of nodal metastasis requires both objective and subjective analyses. In the present study, mediastinal lymph nodes in superficial esophageal carcinoma (SEC) were examined by both EUS appearance and histography, using NIH image software.

Anterior chest wall approach for video-assisted thyroidectomy using a modified neck skin lifting method.

Neck endoscopic surgery is likely to prove less invasive and more cosmetically advantageous than conventional methods. The surgical procedure used for 42 consecutive patients undergoing video-assisted thyroidectomy by the anterior chest wall approach is described herein. A 3-4 cm incision was made at the anterior chest wall 2 cm below the clavicle on the tumor side.

Distribution of lymph node micrometastasis in pN0 well-differentiated thyroid carcinoma.

Background: The role of lymph node dissection in the treatment of differentiated thyroid carcinoma remains controversial, and the benefit of therapy is debatable. This study was designed to identify the precise localization of lymph node micrometastases (LNMM) and map their cervical involvement in relation with the tumor location within the thyroid gland.

Methods: A total of 2551 cervical lymph nodes were obtained from 80 patients with well-differentiated thyroid cancer.
