Most patients who undergo Roux-en-Y gastric bypass (RYGB) experience rapid resolution of type 2 diabetes. Prior studies indicate that this results from more than restriction and weight loss, implicating the rearranged intestine as a primary mediator. It is unclear, however, if diabetes improves because enhanced delivery nutrients to distal increased secretion hindgut signals improve glucose homeostasis, or altered excluded segment proximal intestine. We sought distinguish between these two...
Surgical workflow recognition has numerous potential medical applications, such as the automatic indexing of surgical video databases and optimization real-time operating room scheduling, among others. As a result, phase been studied in context several kinds surgeries, cataract, neurological, laparoscopic surgeries. In literature, two types features are typically used to perform this task: visual tool usage signals. However, mostly handcrafted. Furthermore, signals usually collected via...
Hypothesis: Natural orifice transluminal endoscopic surgery (NOTES) provides the potential for performance of incisionless operations.This would break physical barrier between bodily trauma and surgery, representing an epical revolution in surgery.Our group at IRCAD-EITS (Institut de Recherche contre les Cancers l'Appareil Digestif [Institute Digestive Cancer Research]-European Institute TeleSurgery) has been actively involved development NOTES since 2004 with a dedicated project created to...
The Roux-en-Y gastric bypass and the biliopancreatic diversion effectively induce weight loss long-term control of type 2 diabetes in morbidly obese individuals. It is unknown whether a secondary outcome from treatment obesity or direct result duodenal-jejunal exclusion that both operations include. aim this study was to investigate can independently on resolution obesity-related abnormalities.
Objective To show the feasibility of performing surgery across transoceanic distances by using dedicated asynchronous transfer mode (ATM) telecommunication technology. Summary Background Data Technical limitations and issue time delay for transmission digitized information existing lines had been a source concern about complete surgical procedure from remote distances. Methods verify safety in humans, authors attempted robot-assisted laparoscopic cholecystectomy on 68-year-old woman with...
Objective: To develop a deep learning model to automatically segment hepatocystic anatomy and assess the criteria defining critical view of safety (CVS) in laparoscopic cholecystectomy (LC). Background: Poor implementation subjective interpretation CVS contributes stable rates bile duct injuries LC. As is assessed visually, this task can be automated by using computer vision, an area artificial intelligence aimed at interpreting images. Methods: Still images from LC videos were annotated...
Objective To assess the feasibility, safety, and outcome of laparoscopic liver resection for malignant tumors. Summary Background Data The precise role laparoscopy in malignancies (hepatocellular carcinoma [HCC] metastases) remains controversial despite an increasing number publications reporting benign Methods A retrospective study was performed 11 surgical centers Europe regarding their experience with malignancies. Detailed questionnaires were sent to each surgeon focusing on patient...
Objective This article describes a preliminary work on virtual reality applied to liver surgery and discusses the repercussions of assisted surgical strategy simulation tomorrow's surgery. Summary Background Data Liver is considered difficult because complexity variability organ. Common generic tools for presurgical medical image visualization do not fulfill requirements liver, restricting comprehension patient's specific anatomy. Methods Using data from National Library Medicine, realistic...
Objective: To improve the planning of hepatic surgery, we have developed a fully automatic anatomical, pathological, and functional segmentation liver derived from spiral CT scan.Materials Methods: From 2 mm-thick enhanced scan, first stage automatically delineates skin, bones, lungs, kidneys, spleen by combining use thresholding, mathematical morphology, distance maps. Next, reference 3D model is immersed in image deformed to contours. Then an Gaussian fitting on imaging histogram estimates...
This work presents a predictive-control approach to active mechanical filtering of complex, periodic motions organs induced by respiration or heart beating in robotized surgery. Two different schemes are proposed for the compensation respiratory cardiac motions. For motions, property disturbance has been included into input-output model controlled system so as have robotic learn and anticipate perturbation A new cost function is unconstrained generalized predictive controller (GPC), where...

This paper presents a robotic vision system that automatically retrieves and positions surgical instruments during robotized laparoscopic operations. The instrument is mounted on the end-effector of robot which controlled by visual servoing. goal automated task to safely bring at desired three-dimensional location from an unknown or hidden position. Light-emitting diodes are attached tip instrument, specific holder fitted with optical fibers used project laser dots surface organs. These...
Single-access laparoscopic surgery should offer minimal scarring without compromising surgical outcome. It is enhanced by both innovative port technology and technical expertise learned developing natural orifice transluminal endoscopic (NOTES).Sigmoidectomy in a human via single port.University hospital. Patient A 40-year-old woman with previously documented diverticular abscess.The multichannel (Triport; Advanced Surgical Concepts, Wicklow, Ireland) was placed at the umbilicus. The sigmoid...
Our aim was to evaluate a fluorescence-based enhanced-reality system assess intestinal viability in laparoscopic mesenteric ischemia model.A small bowel loop exposed, and 3 4 vessels were clipped 6 pigs. Indocyanine green (ICG) administered intravenously 15 minutes later. The illuminated with an incoherent light source laparoscope (D-light-P, KarlStorz). ICG fluorescence signal analyzed Ad Hoc imaging software (VR-RENDER), which provides digital perfusion cartography that superimposed the...
