Cor triatriatum sinister (CTS) is a rare congenital cardiac anomaly and is mainly corrected through conventional surgery through sternotomy. We described our successful novel surgical technique of totally robotic correction of CTS in one case of CTS with concomitant repair of atrial septal defect using da Vinci SI Surgical System (Intuitive Surgical, Inc, Sunnyvale, CA USA) with excellent surgical outcome. We conclude that robotic correction of CTS is a feasible and safe alternative to conventional surgical technique...

Computer-assisted surgical (CAS) planning tools are available for craniofacial surgery, but are usually based on computer-aided design (CAD) tools that lack the ability to detect the collision of virtual objects (i.e., fractured bone segments). We developed a CAS system featuring a sense of touch (haptic) that enables surgeons to physically interact with individual, patient-specific anatomy and immerse in a three-dimensional virtual environment. In this study, we evaluated initial user experience with our novel system compared to an existing CAD system...

OBJECTIVE: Precise minimally invasive surgery (MIS) has significant advantages over traditional open surgery in clinic. Although pre-/intra-operative diagnosis images can provide necessary guidance for therapy, hand-eye discoordination occurs when guidance information is displayed away from the surgical area. In this study, we introduce a real 3D see-through guidance system for precision surgery. METHODS: To address the resolution and viewing angle limitation as well as the accuracy degradation problems of autostereoscopic 3D display, we design a high quality and high accuracy 3D integral videography (IV) medical image display method...

Targeted muscle reinnervation (TMR) is a revolutionary surgical technique that, together with advances in upper extremity prostheses and advanced neuromuscular pattern recognition, allows intuitive and coordinated control in multiple planes of motion for shoulder disarticulation and transhumeral amputees. TMR also may provide improvement in neuroma-related pain and may represent an opportunity for sensory reinnervation as advances in prostheses and haptic feedback progress. Although most commonly utilized following shoulder disarticulation and transhumeral amputations, TMR techniques also represent an exciting opportunity for improvement in integrated prosthesis control and neuroma-related pain improvement in patients with transradial amputations...

The robotic surgical system is the result of a long process of development aimed at producing a natural extension of the surgeon's eyes and hands via the intermediation of a computer. In this way, the ease of movement obtained with open surgery is summated with the advantages of the minimally invasive technique. Since 2000, when the first robotic system for surgery was introduced, robot-assisted thoracic surgery (RATS) has been adopted by an increasing number of centres around the world, and today is used in ∼10% of lobectomies in the US...

PURPOSE OF REVIEW: Despite marked improvements in perioperative outcomes, esophagectomy continues to be a high-risk operation associated with significant morbidity and mortality. Progress has been achieved through evidence-based changes in preoperative optimization, intraoperative ventilation strategies, fluid therapy, and analgesia, as well as expedited postoperative recovery pathways. This review will summarize the recent literature on the anesthetic management of patients undergoing esophageal resection...

Spectroscopic diagnostics have been shown to be an effective tool for the analysis and discrimination of disease states from human tissue. Furthermore, Raman spectroscopic probes are of particular interest as they allow for in vivo spectroscopic diagnostics, for tasks such as the identification of tumour margins during surgery. In this study, we investigate a feature-driven approach to the classification of metastatic brain cancer, glioblastoma (GB) and non-cancer from tissue samples, and we provide a real-time feedback method for endoscopic diagnostics using sound...

Transesophageal echocardiography (TEE) is routinely used to provide important qualitative and quantitative information regarding mitral regurgitation. Contemporary planning of surgical mitral valve repair, however, still relies heavily upon subjective predictions based on experience and intuition. While patient-specific mitral valve modeling holds promise, its effectiveness is limited by assumptions that must be made about constitutive material properties. In this paper, we propose and develop a semi-automated framework that combines machine learning image analysis with geometrical and biomechanical models to build a patient-specific mitral valve representation that incorporates image-derived material properties...

The optimal degree of revascularization for patients with chronic multivessel coronary artery disease remains an unsolved issue. Intuitively, complete revascularization decreases cardiovascular events and improves outcomes compared to incomplete procedures, but in recent years the concept of incomplete revascularization moved from a sub-optimal or a defective treatment towards the most appropriate revascularization technique in some categories of patients. A reasonable level of incomplete anatomic revascularization has been shown to be safe and achievable with both percutaneous (PCI) and surgical procedures (CABG), despite with different long-term outcomes...

The da Vinci system (da Vinci Surgical System; Intuitive Surgical Inc.) has rapidly developed in several years from the S system to the Si system and now the Xi System. To investigate the surgical feasibility and to provide workflow guidance for the newly released system, we used the new da Vinci Xi system for transoral robotic surgery (TORS) on a cadaveric specimen. Bilateral supraglottic partial laryngectomy, hypopharyngectomy, lateral oropharyngectomy, and base of the tongue resection were serially performed in search of the optimal procedures with the new system...

PURPOSE: The surgical treatment of many dentofacial deformities is often complex due to its three-dimensional nature. To determine the dental occlusion in the most stable position is essential for the success of the treatment. Computer-aided virtual planning on individualized patient-specific 3D model can help formulate the surgical plan and predict the surgical change. However, in current computer-aided planning systems, it is not possible to determine the dental occlusion of the digital models in the intuitive way during virtual surgical planning because of absence of haptic feedback...

PURPOSE: Navigation systems commonly used in neurosurgery suffer from two main drawbacks: (1) their accuracy degrades over the course of the operation and (2) they require the surgeon to mentally map images from the monitor to the patient. In this paper, we introduce the Intraoperative Brain Imaging System (IBIS), an open-source image-guided neurosurgery research platform that implements a novel workflow where navigation accuracy is improved using tracked intraoperative ultrasound (iUS) and the visualization of navigation information is facilitated through the use of augmented reality (AR)...
