The extent of resection and release of the trachea is important for successful anastomosis. Bilateral bronchial dissection is one of the release techniques for resection of the lower trachea. We present the experience of cervical video-assisted mediastinoscopic bilateral bronchial release for long segmental resection and anastomosis of the lower trachea.

Bronchogenic cysts (BCs) are relatively common congenital anomalies in the mediastinum. Most of the patients with BC can be managed both safely and effectively by minimally invasive methods. Selected patients with a BC in a favorable location can have the cyst partially or completely excised by mediastinoscopic techniques. Herein we report on a case of a left lower paratracheal bronchogenic cyst that was completely resected by a video-assisted mediastinoscopic technique, and we discuss the technical aspects of this procedure.

BACKGROUND: Lumbar Sympathectomy is a surgery for plantar hyperhidrosis, vascular and other reflex sympathetic diseases and has a various indications and physiologic effects. However it is not performed actively compared to thoracic sympathectomy because of its invasiveness. Therefore, we tried to perform lumbar sympathectomy using mediastinoscopy with small incision and introduce this new surgical technique. MATERIAL AND METHOD: From July 2003 to December 2004, 18 patients underwent lumbar sympathectomy with mediastinoscopy at Inje University Sanggye Paik Hospital. There were 12 males and 6 females whose mean age was 24.3+/-8.2 years ranging from 18 to 67. 30 cases of lumbar sympathectomy was performed with mediastinoscopy of which 24 cases were for plantar hyperhidrosis and 6 cases for other diseases. RESULT: Mean operation time was 37.2+/-12.5 minutes and mean post operation hospital stay was 3.1+/-2.2 days. There was one post sympathetic neuralgia and one peritoneal opening. CONCLUSION: Lumbar sympathectomy using mediastinoscopy is a simple and effective technique and has the advantage of cosmetics, post operative pain and hospital stay. However, further studies with large number of cases should be carried out for better outcome.

There are many causes of prolonged postoperative muscle weakness, including drugs, residual anesthetics, cerebrovascular events, electrolyte imbalance, hypothermia, and neuromuscular disease. Neuromuscular diseases are relatively rare, with the most common being myasthenia gravis and Lambert-Eaton myasthenic syndrome (LEMS). We report an unusual case in which a patient who was given a muscle relaxant during mediastinoscopy developed postoperative muscle weakness that was ultimately diagnosed as secondary to LEMS.

Lung cancer has become a leading cause of cancer death in Korea. Accurate staging of non-small cell lung cancer (NSCLC) is essential to the ability to offer a patient the most effective available treatment and the best estimate of prognosis. PET with F-18 fluorodeoxyglucose (FDG) is indicated for the nodal staging of NSCLC and detection of distant metastases. Use of PET for mediastinal staging should not be relied on as a sole staging modality, and positive findings should be confirmed by mediastinoscopy. FDG PET avoids futile surgery by a more accurate selection of patients, especially by the detection of unexpected distant metastases.

Esophagectomy has a high morbidity rate, mainly related to pulmonary complications. The respiratory morbidity of open esophagectomy is high, ranging from 6% to 10%. This high morbidity is partially responsible for the 6~15% mortality rate of esophagectomy. Many techniques of esophagectomy without thoracotomy have been described since the initial report of Orringer and Sloan. Endoscopic microsurgical dissection of the esophagus was clinically introduced in 1989. Endoscopic microsurgical dissection of the esophagus was developed as a minimally invasive procedure that avoids thoracotomy and provides precise vision during the operation in order to reduce mediastinal trauma and to improve the peri-and post-operative situation. A 20 year-old women who accidentally swallowed about 150 cc of glacial acetic acid underwent an esophagectomy using the operating mediastinoscopy, cervical esophagogastric anastomosis, pyloromyotomy, and feeding jejunostomy tube placement for esophageal stricture. The postoperative course was uneventful and the patient was discharged on the 17th postoperative day. Our clinical experience shows that endoscopic microsurgical dissection of esophagus is a safe and feasible method because it offers excellent optical control and enables the surgeon to operate in a minimally invasive manner.

BACKGROUND: Video-thoracoscopy is known to be an useful method to provide accurate pre-resectional staging in patients with lung cancer in addition to the conventional radiologic studies and mediastinoscopy, for the pleural cavity is inspected directly and biopsy specimens can be obtained. This study is undertaken to evaluate how video-thoracoscopy can be used in deciding pre-resectional stage. MATERIAL AND METHOD: Video-thoracoscopy was performed in patients with lung cancer who were scheduled for surgical resection based on the radiologic staging and mediastinoscopic biopsy. 37 patients were included in this study. Pre-thoracoscopically 18 cases were in TNM stage 1, 7 in stage 2, and 12 in stage 3. RESULT: In 15 of 37 cases, video-thoracoscopy could not be performed effectively due to heavy adhesions in the pleural cavity, diaphragmatic and chest wall invasion of tumor and bulky tumor mass es. Mediastinal lymph nodes were positive postresectionally in 6 of these 15 cases. In 22 cases, video-thoracoscopy was performed as usual. Positive mediastinal lymph nodes were identified in 2 cases and exploratory thoracotomy was prevented. Surgical resection were carried out in remaining 20 cases and 5 cases among them had positive mediastinal lymph nodes. CONCLUSION: We believe that it is difficult to perform pre-thoracotomy video-thoracoscopy for all lung cancer patients for there were many cases that thoracoscopy could not be undertaken due to heavy adhesions in the pleural cavity, tumor involvement of the chest wall and/or diaphragm and bulky tumor mass. However we think it is helpful in preventing unnecessary exploratory thoracotomy for some patients with lung cancer whom pre-thoracotomy video-thoracoscopy was carried out.

Pheochromocytomas are neuroendocrine tumors of chromaffin cell that originate in the paraganglia of the adrenal medulla. Approximately 10% of pheochromocytomas are found in the extra-adrenal paraganglia and are called paragangliomas. However, cases of middle mediastinal paragangliomas are very rare. In this case, the patient presented with a voice change and a headache. A middle mediastinal soft tissue mass with marked enhancement was detected on computed tomography of the chest. The 24-hour urine catecholamine level was markedly elevated. The middle mediastinal mass was biopsied via mediastinoscopy and the resulting immunohistochemical staining was compatible with a diagnosis of middle mediastinal paraganglioma. The mass was resected surgically and the symptoms were relieved.
