With recent advancements of technology, radiofrequency ablation has become one of the most used techniques to treat liver tumors. But radiologists still have to face the difficulty of planning their treatment while only relying on 2D slices acquired from CT-scan. We present in this paper a tool called RF-Sim, being part of a complete 3D reconstruction and(More)
In the last few years, radiofrequency ablation has become one of the most promising techniques to treat liver tumors. But radiol-ogists have to face the difficulty of planning their treatment while only relying on 2D slices. We present here a realistic radiofrequency abla-tion simulation tool, coupled with a 3D reconstruction and visualization project. They(More)
Pseudozyma aphidis is an environmental Basidiomycete yeast, and has been involved in the ten past years in rare cases of invasive infection. Pseudozyma species are naturally resistant to caspofungin and often present decreased susceptibility or resistance to fluconazole. This fungus may be difficult to recognize and misidentifications are reported with(More)
To improve therapy research against cancer, we propose a robotized computer assisted system for needle insertion devoted to the small animal. The system is composed of a robotic arm on which the needle is attached and two cameras rigidly linked. It needs a preoperative CT acquisition in which the biologist defines an entry point and the target he wants to(More)
—Surgical workflow recognition has numerous potential medical applications, such as the automatic indexing of surgical video databases and the optimization of real-time OR scheduling, among others. As a result, phase recognition has been studied in the context of several kinds of surgeries, such as cataract, neurological, and laparoscopic surgeries. In the(More)
Introduction. The only curative therapeutic approach for renal cell carcinoma (RCC) is surgery. Laparoscopic surgery for RCC has become an established surgical procedure with equivalent cancer-free survival rate, following the same surgical oncological principles as open surgery. Metastatic RCC of the gallbladder is a rare phenomenon. Hence, there are few(More)
Laparoscopic cholecystectomy is still associated with a considerable rate of biliary injuries and related strictures. Advances in interventional endoscopy and percutaneous techniques have made stenting a preferred treatment modality for the management of these strictures. We report successful 20 years of follow-up of a case of trans-hepatic metallic(More)
BACKGROUND Fully covered self-expanding metal stent (SEMS) placement has been successfully described for the treatment of malignant and benign conditions. The aim of this study is to evaluate our experience of fully covered SEMS placement for post-operative foregut leaks. MATERIALS AND METHODS Retrospective analysis was done for indications, outcomes and(More)
Computer-assisted surgery led to a major improvement in medicine. Such an improvement can be summarized in three major steps. The first one consists in an automated 3D modelling of patients from their medical images. The second one consists in using this modelling in surgical planning and simulator software offering then the opportunity to train the(More)
