Endotracheal surgery for leiomyoma of the trachea. (1/4)
A 61-year-old male was found to have a tracheal tumor, which was noted at the time of screening by a chest X-ray study. The tumor arose from the membranous portion 4 cm above the carina and was proven by biopsy to be a leiomyoma. Because the disease is a benign tumor, all methods for resection, including bronchoscopic techniques, were thus considered. We performed an endotracheal operation via a window made by an incision of the cartilagenous portion, and removed the tumor through an anterior approach. This type of endotracheal operation is one of the surgical procedures for the removal of benign tracheal tumors.

Miniature ultrasound transducers (12.5 MHz) housed in 9 Fr catheters were passed through a laparoscope or mediastinoscope to image a variety of normal and abnormal structures within the peritoneal cavity and mediastinum in 20 patients. These transducers made it possible to visualize the gallbladder and bile ducts and evaluate for the presence of stones, to detect masses and provide guidance for their aspiration or biopsy, and to image the internal structures of the ovary and fallopian tube. In addition, these miniature transducers were used to locate such normal vital structures as blood vessels, thereby allowing the surgeon to decide on the best approach for dissection during mediastinoscopy. During conventional surgery, the surgeon or gynecologist can palpate an area of abnormality not directly visualized. However, during laparoscopy and mediastinoscopy direct palpation is not possible. Therefore, it is important to find another method to determine what structures lie beneath the visualized surface. These miniature ultrasound transducers appear to offer a means for making such determinations. (+info)A mediastinoscope is not a medical condition, but rather a medical device used in the field of medicine. It is a type of endoscope that is used to examine the mediastinum, which is the area in the chest between the lungs that contains the heart, trachea, esophagus, and other vital organs and tissues.
Mediastinoscopes are thin, rigid tubes with a light and a camera attached to one end. They are inserted through a small incision made at the base of the neck, allowing the physician to visualize and access the mediastinal structures for diagnostic or therapeutic purposes. The use of mediastinoscopes is typically performed under general anesthesia in a surgical setting.
The medical definition of 'Mediastinoscope' would be:
A long, thin, rigid tube with a light and camera attached to one end, used in mediastinoscopy to examine the structures of the mediastinum and obtain tissue samples for diagnostic purposes.
