Die proximale extraartikuläre Tibiafraktur
2002
Die Stabilisierung proximaler extraartikularer Tibiafrakturen stellt unter Verwendung der gebrauchlichen Osteosyntheseverfahren unverandert ein Problem dar. Die Wahl des Operationsverfahrens hangt unter anderem von der Situation der oftmals erheblich kompromittierten frakturumgebenden Weichteile ab. An der proximalen Tibia besteht zusatzlich das Problem von Fehlstellungen der Fraktur. Neben der Gefahr einer intraoperativen Frakturdislokation durch Muskelzug und den operativen Zugang kommt es gehauft zu sekundaren Fehlstellungen durch relative Implantatinstabilitat. Es wurden verschiedene Verfahren zur Versorgung dieser Frakturen entwickelt; sie zeichnen sich durch differierende biomechanisc…
Chirurgische Option zur Behandlung von Interstitieller Zystitis
2007
Sind die konservativen therapeutischen Möglichkeiten zur Behandlung der Interstitiellen Zystitis ausgeschöpft, stehen verschiedene operative Methoden zur Verfügung. Denervierungsoperationen werden heutzutage weitestgehend als ungeeignet angesehen, gute Erfolge werden mit der supra- oder subtrigonalen Zystektomie und Blasenaugmentation erzielt. Als ultima ratio gilt die Zystourethrektomie mit heterotoper Harnableitung.
Chirurgie cardiaque sous circulation extra-corporelle et ses biomarqueurs : rôle du Growth / Différentiation Factor 15 (GDF 15) : études cliniques
2016
Ischemic cardiac diseases are the most frequent and deleterious pathologies leading to important cardiovascular-related mortality worldwide. One of the alternative therapies consists to treat these patients using cardiac surgery. Cardiopulmonary bypass was developed to greatly improve this surgical procedure. However, some adverse effects can occur during cardiac surgery associated with cardiopulmonary bypass due to the inflammatory response. This phenomenon is the result of various mechanisms including oxidative stress and inflammatory cytokines which lead to multi-organ failure and then to myocardial and renal injuries occurring during the peri- and post-operative periods.The first part o…
Secondary technical resectability of colorectal cancer liver metastases after chemotherapy with or without selective internal radiotherapy in the ran…
2019
Background: Secondary resection of initially unresectable colorectal cancer liver metastases (CRLM) can prolong survival. The added value of selective internal radiotherapy (SIRT) to downsize lesions for resection is not known. This study evaluated the change in technical resectability of CRLM with the addition of SIRT to FOLFOX-based chemotherapy. Methods: Baseline and follow-up hepatic imaging of patients who received modified FOLFOX (mFOLFOX6: fluorouracil, leucovorin, oxaliplatin) chemotherapy with or without bevacizumab (control arm) versus mFOLFOX6 (with or without bevacizumab) plus SIRT using yttrium-90 resin microspheres (SIRT arm) in the phase III SIRFLOX trial were reviewed by thr…
Évaluation de la pratique chirurgicale dans le traitement du cancer bronchique en France à partir de la base nationale du PMSI
2019
Background - In recent years, improving the quality of care has been a concern for health professionals in France, through the certification of institutions, accreditation and continuous professional development. Evaluation of these different measures has rarely been carried out. The objective of the study was to evaluate the quality of surgical management of lung cancer in different regions using hospital mortality as an indicator. Method - From the national database of the Program of Medical Information Systems (PMSI), data on all patients who had undergone surgery for lung cancer were extracted as well as the characteristics of the centers. The main outcome criterion was hospital mortali…

Ce troisième rapport de l'Observatoire national de la démographie des professions de santé comporte une synthèse générale assortie de préconisations et de quatre tomes thématiques : la médecine générale (tome 1), les internes en médecine (tome 2), la profession de chirurgien dentiste et les métiers de la périnatalité (tome 3), les métiers de la cancérologie (tome 4).
Augmented reality based middle and inner ear surgical procedures
2020
Otologic procedures involve manipulation of small, delicate and complex structures in the temporal bone anatomy which are in close proxmity of critical nerves and blood vessels. Augmented reality (AR) can highly benefit the otological domain by providing supplementary anatomical and navigational information unified on a single display. However, despite being composed of mainly rigid bony structures, the awareness and acceptance of possibilities of AR systems in otology is fairly low. This project aims at developing video-based AR solutions for middle and inner ear surgical procedures.We propose two applications of AR in this regard. In the first application, information about middle ear cle…
Augmented Reality in minimally invasive otologic surgery and transmodiolar cochlear implantation
2021
Optimal exposure is necessary for minimally invasive otologic surgery. Augmented reality allows to enrich the real environment by adding data without replacing it by a virtual environment and to view this information on a single screen by combining the vision of the operating field and the imaging. This technique is very little described in otology in the literature. This project aims to develop augmented reality solutions for otological surgeries and transmodiolar implantation. To prepare this augmented reality project, we studied the visualization of the middle ear by a virtual endoscope based on preoperative high resolution CT-scans. Then, we worked on the application of augmented realit…
Dispositif virtuel d'aide à la chirurgie de l'épaule
2008
The goal of this research is to design a virtual reality prototype to assit an orthopedic surgeon during the replacement of the glenohumeral joint by prosthesis. This system aims to optimize the movements of prosthesized shoulder joint from a choice of various scenarios of pose. These works encompasses several topics such as : orthopedic surgery, image analysis, computer graphics and virtual reality. The chosen process includes a phase of modelling of the bony part of the articulation by simple geometric forms, this model is parameterized from radios or CT scans ; a phase of simulation of the movements of healthy glenohumeral joint ; nally the phase of simulation of cutting and drilling wit…
