Neue Technik

Fragestellung: Die dieser Untersuchung zugrunde liegende Frage war, ob das angewandte Ausbildungskonzept geeignet war, um am Beispiel der Einführung der laparoskopischen Cholezystektomie eine neue Operationsmethode in einer universitären Ausbildungsklinik mit einer grossen Anzahl Chirurgen zu etablieren. Patienten und Methodik: Seit Einführung der ersten laparoskopischen Cholezystektomie wurden alle Cholezystektomien während zwei Jahren (Mai 1990 bis Mai 1992) prospektiv erfasst. Ein Ausbildungskonzept wurde gewählt, bei dem jeweils ein Operateur durch einen Tutor geschult wurde und so 15 konsekutive Eingriffe durchführte, um dann die Technik einem weiteren auszubildenden Chirurgen zu instruieren. Resultate: In zwei Jahren wurden 355 Patienten cholezystektomiert. 60% der Operationen wurden laparoskopisch durchgeführt oder begonnen. 40% der Operationen wurden offen durchgeführt. In den ersten zwei Jahren konnten 13 Operateure (durchschnittlich 16 Operationen / Operateur , range 1 - 60) in die neue Technik eingeführt werden. Es traten keine schweren Komplikationen, insbesondere keine Gallenwegsverletzungen in dieser Einführungsphase auf. Diskussion: In der Literatur wird dieses Vorgehen bei der Einführungsphase seit 1992 wiederholt vorgestellt, diskutiert und empfohlen. Zwischenzeitlich gibt es Richtlinien von Fachgesellschaften und nationalen Institutionen, welche die Ausbildung zur Ausführung neuer chirurgischer Techniken reglementieren. In den letzten Jahren verlagern sich die ersten Ausbildungsschritte in Richtung Trainingskurse an skill-stations und virtual reality Trainer. Schlussfolgerung: Das beschriebene Ausbildungskonzept bewährte sich in der Einführungsphase der laparoskopischen Cholezystektomie zu Beginn der 90er-Jahre.

The article´s goal isto determine if socioeconomic factors influence the postoperative complications of cholecystectomy. For this, the observational study was defined, analytical and quantitative study was conducted in 100 patients who underwent cholecystectomy. A logistic regression model was applied in which risk factors, socioeconomic characteristics, along with a control variable, were incorporated as variables. Three models were run with alternative dependent variables that are delimited by the type of postoperative complication recorded. The results found showed that women show a higher risk of presenting complications after cholecystectomy, the same occurs in older patients. Likewise, the risk is much lower in people with higher education levels and in patients who underwent laparoscopic cholecystectomy, they only have a 5% risk of presenting complications. Postoperative complications after cholecystectomy are minimized by using the laparoscopic technique and socioeconomic factors would influence the risk of suffering postoperative complications after said surgery, which makes laparoscopic cholecystectomy a safe operation with many other benefits and advantages over traditional or conventional surgery.

Complication Of Surgery

Laparoscopic cholecystectomy is one of the procedures through which gall bladder can be removed. Acute cholecystitis was considered a contraindication for laparoscopic procedure but with time and experience this shortcoming is now overcome. Here is a study of 32 patients who were selected for laparoscopic cholecystectomy. Among them, 29 patients were operated by laparoscopic method and rest three patients were converted. This study showed the appropriate time for surgery, technical difficulties and the complication of surgery. It may be concluded that laparoscopic cholecystectomy is feasible and beneficial to the patient with acute cholecystitis in its early phase, if necessary support and expertise is available.

The Swiss geologist and mineralogist Louis-Albert Necker belonged to a family rich in scientific celebrities. Though a professor at the Académie de Genève for 25 years and author of numerous publications, he is mainly remembered today for his description of the “Necker cube” optical illusion and for leaving Geneva to spend the last 20 years of his life in Portree on the Isle of Skye. As a first step towards assessing Necker's contribution to science, a full list of his publications is presented, with comments about their citation in previous bibliographies and about published translations and abridgements. Information about the surviving specimens from his scientific collections, most of which are in the Muséum d'histoire naturelle de Genève, is also presented.
