HYPOTHESIS Natural orifice transluminal endoscopic surgery (NOTES) provides the potential for performance of incisionless operations. This would break the physical barrier between bodily trauma and surgery, representing an epical revolution in surgery. Our group at IRCAD-EITS (Institut de Recherche contre les Cancers de l'Appareil Digestif [Institute of(More)
BACKGROUND Total mesorectal excision (TME) offers the lowest reported rates of local recurrence and the best survival results in patients with rectal cancer. However, the laparoscopic approach to resection for colorectal cancer remains controversial due to fears that oncologic principles will be compromised. We assessed the feasibility, safety and long-term(More)
Minimally invasive surgery represents one of the main evolutions of surgical techniques aimed at providing a greater benefit to the patient. However, minimally invasive surgery increases the operative difficulty since the depth perception is usually dramatically reduced, the field of view is limited and the sense of touch is transmitted by an instrument.(More)
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 the issue of time delay for transmission of digitized information across existing telecommunication lines had been a source of concern(More)
OBJECTIVE This article describes a preliminary work on virtual reality applied to liver surgery and discusses the repercussions of assisted surgical strategy and surgical simulation on tomorrow's surgery. SUMMARY BACKGROUND DATA Liver surgery is considered difficult because of the complexity and variability of the organ. Common generic tools for(More)
OBJECTIVE To compare technical aspects and postoperative outcomes of laparoscopic left colectomy in obese and nonobese patients. SUMMARY BACKGROUND DATA Obesity has been generally associated with increased surgical risk. The data regarding outcomes after laparoscopic colectomy in obese and nonobese patients are limited and quite controversial; however,(More)
BACKGROUND Natural orifice specimen extraction (NOSE) in colorectal surgery prevents the need for an enlarged port site or minilaparotomy to extract the surgical specimen. The downside of this technique may be an increased risk of bacterial contamination of the peritoneal cavity from the external milieu. The aim of this study was to prospectively analyze(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)
