Endoscopic microsurgical dissection of the esophagus. Results in an animal model.
Blunt dissection of the esophagus is considered the least invasive technique in the treatment of either benign or malignant diseases of the esophagus. Its disadvantage is that it has to be carried out blindly. The results may be uncontrollable hemorrhage, unrecognized injuries to the trachea, and damage to the recurrent laryngeal nerve. In order to reduce the degree of invasiveness a new endoscopic microsurgical technique for the dissection of the esophagus has been developed and tried out in animals. This paper presents the operative technique. Our new endoscopic microsurgical technique obviates a thoracotomy, while direct endoscopic vision results in improved dissection. The magnified end…
Die dynamische 31-Phosphor-Magnetresonanz-Spektroskopie des M. quadriceps: Einfluß von Geschlecht und Alter auf spektroskopische Parameter
PURPOSE 31P-MRS is used to assess the influence of sex und age on quadriceps muscle metabolism before and after exercise. MATERIALS AND METHODS 32 healthy volunteers (15 women, 17 men, mean age: 38 +/- 17 yrs.) were examined by dynamic phosphorus-31 (31P) magnetic resonance spectroscopy (MRS). In the magnet, the quadriceps muscle was stressed by an isometric und an isotonic form of exercise until exhaustion, respectively. RESULTS Resting conditions: With increasing subjects' age, the ratio beta-adenosine triphosphate/total phosphate decreased (r = -0.37; p = 0.02). With increasing subjects' age, the ratios inorganic phosphate/phosphocreatine (r = 0.79; p = 5 x 10(-8), phosphomonoester/beta-…
Kann die endoskopisch-mikrochirurgische Dissektion der Speiseröhre zur Reduzierung pulmonaler Komplikationen nach Osophagusresektion beitragen? — Eine vergleichende tierexperimentelle Studie
Resektionen der Speiserohre sind bis zu 50% mit postoperativen pulmonalen Komplikationen belastet. Als Ursachen werden bereits intraoperativ beginnende Veranderungen der Hamodynamik des Lungenkreislaufes und des Gasaustausches diskutiert. Mit der Endoskopisch-Mikrochirurgischen Dissektion der Speiserohre (EMDO) haben wir eine Methode entwickelt, bei der mit Hilfe eines speziellen Operationsendoskopes die Speiserohre einschlieslich anhangender Lymphknoten von einem linksseitigen cervicalen Zugang aus exakt freiprapariert werden kann.
Wirbelsäulenmanifestationen der chronischen rekurrierenden multifokalen Osteomyelitis (CRMO)
Chronic recurrent multifocal osteomyelitis (CRMO) is a systemic osteo-articular disease that is characterized by a sterile, primarily chronic osteomyelitis with various distribution patterns of the individual lesions. In this article, we describe the "axial type" with predominant involvement of the spine, which represents 13 of our 41 CRMO cases of different age groups. The important element of its diagnosis is the typical lympho-plasmacellular spondylitis that can be detected and staged by scintigraphy, MRI and conventional radiography. Potentially affected are all vertebrae from the mid-cervical spine to the sacrum. One or several segments can be involved, sometimes as transient inflammat…
