The authors draw attention to cervical spine disorders that limit mobility of the vertebrae and thereby interfere with esophagoscopy. Four orthopedic disorders that either fuse the cervical spine or produce massive osteophytes are discussed and exemplified by specific cases, and appropriate techniques for endoscopy are recommended.

Metastatic tumors from extrathoracic sources appear in the mediastinum infrequently and from a variety of locations. In this series of approximately 350 malignancies of the mediastinum, 20 (6%) originated from the breast, prostate, kidney, pelvis, and gastrointestinal tract. A radiologic review of these cases does not identify a unique pattern, although paratracheal masses present most often, while unilateral hilar adenopathy occurs somewhat less frequently. The history of previous surgery for malignancy suggests metastatic disease into the mediastinum. However, other entities of second primaries, lymphoma, Hodgkin's disease, and benign processes warrant consideration. Mediastinoscopy is reemphasized as a valuable diagnostic technique for the solution of these problems.
Surgery upon the cervical vertebrae may produce prolonged dysphagia due to regional damage, hemorrhage, infection, and denervation. Cases illustrating these problems are presented with attention to the progression of the clinical course and the diagnostic modalities of radiology and endoscopy. Methods of prevention are emphasized and the therapeutic plan is outlined.
