    Description / Table of Contents: Summary High pressure lumbar air insufflation and endoscopical surgical technique and control improve surgical results and widen indications for the transsphenoidal approach to pituitary adenomas. These complementary methods require a sitting position for the patient and an axial approach to the sella turcica. By lumbar high pressure insufflation even very big pituitary adenomas may often be brought into the operation field and make possible a complete extirpation by a transsphenoidal approach. This possibility is increased by an operative technique under endoscopic control, the latter contributing considerably to complete tumour extirpation, especially with endocrine-active tumours.
    Notes: Zusammenfassung Bei transnasal durchgeführten mikrochirurgischen Operationen von Hypophysentumoren läßt sich durch die zusätzliche Anwendung von lumbaler Überdruckluftfüllung und endoskopischer Operationstechnik und -kontrolle eine weitere Verbesserung der Operationsergebnisse sowie eine Erweiterung der Indikationen für den nasalen Zugangsweg erreichen. Die sitzende Lagerung des Patienten mit achsengerechtem Zugangsweg zur Sella turcica schafft, wie oben angeführt, die Voraussetzungen zum Einsatz dieser ergänzenden Methoden. Durch die lumbale Luftinsufflation unter Überdruck lassen sich auch sehr große Hypophysentumoren häufig so in das vorgegebene Operationsfeld verlagern, daß eine vollständige Operation vom transnasalen Zugang aus möglich ist. Diese Möglichkeit wird durch den Einsatz der operativen Technik unter endoskopischer Kontrolle noch erweitert; letztere trägt auch wesentlich zur vollständigen Tumorentfernung, insbesondere bei endokrin aktiven Tumoren, bei.

    Notes: Summary 32 cases of negative exploration in a joint follow-up series of 3,032 lumbar disc operations are described. Data from 15 hospitals were analyzed by means of questionnaires and computer-aided analysis. Detailed information is given about pre as well as intraoperative findings. The causes of negative lumbar disc exploration can be divided into two groups. 1. Genuine misdiagnosis where other causes are responsible for the symptoms, and 2. poor technique where despite genuine disc prolapse no evidence was found at operation. The most important causes in the first group were osteochondrotic compression, distended epidural veins, and root tension. The results are less favourable in these patients than in the overall series but, compared to the other complicated courses, the results were markedly better. A review of the literature is given, the possible causes for negative explorations are discussed, and a directive is established for the surgical procedure in cases where an expected prolapse is not found at operation.
