    Notes: Abstract  We describe a patient with recurrent intestinal bleeding and sigmoid perforation due to amyloidosis. Hartmann’s procedure was carried out with resection of the diseased sigmoid colon and by performing a terminal colostomy. The postoperative course was uneventful, but the patient died 3 months later of lobar pneumonia and multiple organ system failure.

    Notes: Summary Among the different types of esophageal wall injuries Boerhaave's syndrome is associated with the highest morbidity and mortality. The classical history of retching or vomiting and retrosternal splitting pain is indicative. Roentgenograms of the chest and esophagogram with a water soluble contrast medium are able to reveal the perforation in most cases. Esophagoscopy has been recommended for diagnosis, but its use is unnecessary and frequently contraindicated. Spontaneous perforation of the esophagus should be treated by prompt surgical intervention: left side thoracotomy, direct closure of the perforation by monolayer suture, and adequate mediastinal and pleural drainage. The treatment of esophageal perforation after late diagnosis is considerably more complicated and may consist in a drainage only.

    Notes: Abstract This study was designed to investigate whetherin combined stomach, small bowel, and pancreas transplantation allograft rejection occurs in the individual organs concomitantly and with the same intensity. Heterotopic enbloc transplantation of the stomach, small bowel, and pancreas was performed in a Lewis-to-Brown Norway rat combination. Group 1 animals received no immunosuppressive therapy while animals in group, 2 were treated with cyclosproin (10 mg/kg body weight, orally) daily. Grafts were histologically evaluated on the 5th (subgroups 1a and 2a) and 10th (subgroups 1b and 2b) postoperative days. The degree of rejection was defined as moderate, intermediate, or severe according to predefined criteria. The results indicate that the small bowel is more susceptible to rejection than either the stomach or the pancreas. Mucosal biopsies of the stomach are unlikely to provide a reliable guide to rejection in the small bowel.

    Description / Table of Contents: Zusammenfassung Eine entsprechende Motilität eines Dünndarmtransplantats ist für seine resorptive Funktion sowie auch für die Selbstreinigung des Darms von grundlegender Bedeutung. In der Literatur finden sich einige Angaben über Störungen der Motilität nach Denervation oder Transplantation, jedoch keine vergleichende Untersuchung über den Einfluß einer akuten Abstoßung auf die Darmmotilität. Es wurde deshalb ein Modell erarbeitet, das folgende Kriterien erfüllen sollte: eine orthotope Position des Transplantats, ein ausreichender Ernährungszustand des Versuchtstiers auch bei mangelhafter Funktion des Transplantats, dauerhaft implantierte Elektroden sowohl am Transplantat als auch am korrespondierenden Segment des Eigendarms sowie die Möglichkeit der Transplantation in isogener oder allogener Kombination. Von Lewis-Spendertieren wurden 10 cm proximales Jejunum 5 Lewis-Empfängern in orthotoper Position knapp distal der Treitz-Flexur ohne eine Resektion von Eigendarm interponiert. Am Transplantat sowie am anschließenden Eigendarm wurden jeweils 3 bipolare Elektroden fixiert und serienmäßig elektromyographische Untersuchungen bis zum Ende der 3. postoperativen Woche unternommen. Am Transplantat lassen sich unabhängig vom Eigendarm ablaufende Zyklen migratorischer myoelektrischer Komplexe bereits ab dem 5. postoperativen Tag und in der Folge über 3 Wochen beobachten. Die Schrittmacherfrequenz der Transplantate ist gleich der Frequenz des transsezierten Eigendarms. Dieses frühe Wiedereintreten einer quantifizierbaren Darmmotorik macht das gewählte Modell geeignet für eine Reihe von Untersuchungen, insbesondere aber zur Untersuchung des Einflusses der Abstoßung auf die Motilität, da auch in stark allogenen Kombinationen der Darm von Lewis-Ratten nicht vor dem 6. postoperativen Tag histologische Zeichen einer Abstoßung zeigt.
    Notes: Summary Adequate motility of a small bowel transplant is a prerequisite for its resorptive function as well as its self-purging capacity. The literature contains some reports on changes in motility following denervation or transplantation, but none on the impact of acute rejection on motility of small bowel grafts. Therefore an experimental model was established to meet the following criteria: orthotopic position of graft, adequate nutritional status even when graft is functionally impaired, chronically implantable electrodes attached to graft and corresponding segment of native bowel, isogeneic or allogeneic set-up. 10 cm of proximal jejunum were transplanted from Lewis donors to five Lewis recipients in an orthotopic position just distal of the ligament of Treitz without resection of native small bowel. Three bipolar electrodes were sutured to the graft and the same number to the subsequent recipient bowel. Serial myoelectric measurements were taken until the end of week 3. From day 5 on, migratory myoelectric complexes independent of myoelectric activities of native bowel were recorded. Pacemaker frequency of the graft was found to be the same as that of the transsected native small bowel. This early reappearance of myoelectric activities makes this model suitable for comparative studies of small bowel transplant motility and in particular its changes during rejection, since even in strongly allogeneic combinations Lewis small bowel does not show histological signs of rejection before day 6.

    Description / Table of Contents: Zusammenfassung Aufgrund des morphologischen Erscheinungsbildes and des klinischen Verlaufes bei 30 Brustkrebs-Patientinnen können 2 verschiedene Typen von Lokalrezidiv nach chirurgischer Primärbehandlung definiert werden: Typ I — eindeutig subcutan gelegene Knoten mit guter Langzeitprognose, Typ II — vorwiegend multiple intracutane Lasionen, die in den allermeisten Fallen eine Generalisierung des Krebsleidens signalisieren. Die sich daraus ergebenden therapeutischen Konsequenzen sind weite Excision and eventuell Nachbestrahlung beim Typ I, wahrend der Typ II eine systemische Tumortherapie verlangt.
    Notes: Summary According to the morphological appearance and the clinical course of 30 breast cancer patients, two different types of local recurrence after primary surgical treatment have been defined: type I — clearly subcutaneous lumps associated with good long-term prognosis; type II — mostly multiple intracutaneous lesions, which in the majority of cases seem to indicate generalization of the disease. While local excision followed by irradiation may be sufficient to control the disease in type I recurrence, type II lesions require systemic tumor therapy.
