Background The formation of professional networks and cooperations – in addition to any qualified good education – seems fundamental for a successful career. In a number of disciplines, various symposia or conferences exist. In the field of microsurgery, however, a specific, guided and designated opportunity for junior scientists to network with one another has been missing so far. Methods In 2017, a science academy was initiated for the first time by the German-speaking Association for Nerves and Vessels (DAM) with the goal of bringing together and networking microsurgically researching young physicians and scientists. This was intended to happen on a small scale once a year in order to develop synergies for joint research projects. For this purpose, motivated junior researchers were individually selected by their mentors and sent to the academy by the boards of research institutions that are organized in the DAM. After getting to know each other in a relaxed atmosphere, the participants were given the opportunity to present their respective research project within the framework of thematic blocks and moderated by experienced mentors. Each presentation was followed by a round table discussion and small group work, in which knowledge and methods were exchanged and points of contact for possible later cooperation were identified. Results In the past 3 years, the DAM Science Academy proved to be an optimal format to initiate and promote networks of young researchers comprising microsurgically interested physicians and scientists. There were many lively and in-depth discussions, which were mainly due to the open working atmosphere and the obligation to confidentiality. Most of the synergies were shown i. a. in the field of angiogenesis, bioreactor, carcinoma-ADSC interactions, stem cells, AV loop model, ischemia/reperfusion, and nerve regeneration. The participants consistently gave a very positive feedback in the final evaluation with the wish to con, BACKGROUND: The formation of professional networks and cooperations - in addition to any qualified good education - seems fundamental for a successful career.

Zusammenfassung: GRUNDLAGEN: Die Abdominalregion ist eine vielseitige Quelle für mehrere Gewebe, welche als Lappen zur Wiederherstellung der weiblichen Brust geeignet sind. Diese beinhalten den gestielten und freien Transverse Rectus Abdominis Myocutaneous Lappen (TRAM), den Deep Inferior Epigastric Perforator Lappen (DIEAP) und den Superficial Inferior Epigastric Lappen (SIEA). METHODIK: Diese Übersicht stellt Geschichte und Technik der Wiederherstellung der Brust mittels Lappen vom Abdomen dar. Alle relevanten Studien und Erfahrungen wurden berücksichtigt. ERGEBNISSE: Der Entscheidungsprozess zur Lappenwahl ist komplex und abhängig von einer Reihe von Faktoren, wobei Lappen mit niedrigerer Hebemorbidität deutliche Vorteile zeigen und ein postoperativ verbessertes ästhetisches Resultat der Hebestelle die Patientenakzeptanz deutlich erhöhen kann. SCHLUSSFOLGERUNGEN: In dieser Übersicht werden Anatomie und präoperative Planung in dieser Spenderregion, Fragen zur intraoperativen Entscheidungsfindung sowie Resultate und Patientenzufriedenheit behandelt

The aim of the study was to evaluate whether complication rate, costs, operation times, and hospitalization times differed in two different patient groups: in group 1, frozen section analysis of the sentinel lymph node and lymph node dissection were carried out in the same operation. In group 2, normal investigation of the sentinel lymph node and lymph node dissection were done in a second operation. One hundred thirty-five patients with cutaneous melanoma were included. Hospitalization times, costs, complication rates, and operation times of two-stage and one-stage lymph node dissection of the draining area after detection of metastases in the sentinel lymph node were retrospectively compared. Lymph node metastasis in the sentinel lymph node was found in 23 patients. In 11 patients, removal of the sentinel lymph node and dissection of the lymph node basin was performed in the same operation. In 12 patients, a two-stage procedure was the treatment of choice. Operation times were not different in the two groups (p=0.87) while two-stage operation patients were hospitalized significantly longer (14.2±9.7 vs 23.9±24days; p=0.01) and costs were significantly higher (7,836.90±2,397.95 Swiss francs vs 5,279.40±1,994.90 Swiss francs). In addition, more complications were found in the two-stage group
