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)
Surgical workflow recognition has numerous potential medical applications, such as the automatic indexing of surgical video databases and the optimization of real-time operating room scheduling, among others. As a result, surgical phase recognition has been studied in the context of several kinds of surgeries, such as cataract, neurological, and(More)
Medical image processing led to a major improvement of patient care. The 3D modeling of patients from their CT-scan or MRI thus allows a better surgical planning. Simulation offers the opportunity to train the surgical gesture before carrying it out. And finally, augmented reality provides surgeons with a view in transparency of their patient which, in the(More)
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)
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)
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)
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)
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)
The tool presence detection challenge at M2CAI 2016 consists of identifying the presence/absence of seven surgical tools in the images of cholecystectomy videos. Here, we propose to use deep architectures that are based on our previous work where we presented several architectures to perform multiple recognition tasks on laparoscopic videos. In this(More)
AIM To compare short-term results between laparoscopic hepatectomy and open hepatectomy using a propensity score matching. METHODS A patient in the laparoscopic liver resection (LLR) group was randomly matched with another patient in the open liver resection (OLR) group using a 1:1 allocated ratio with the nearest estimated propensity score. Patients of(More)
