With the recent advances in eye tracking technology, it is now possible to track surgeons' eye movements while engaged in a surgical task or when surgical residents practice their surgical skills. Several studies have compared eye movements of surgical experts and novices and developed techniques to assess surgical skill on the basis of eye movement utilizing simulators and live surgery. None have evaluated simultaneous visual tracking between an expert and a novice during live surgery. Here, we describe a successful simultaneous deployment of visual tracking of an expert and a novice during live laparoscopic cholecystectomy...

Background: Osteochondral lesions (OCL) of the ankle are a common cause of ankle pain. Although the precise pathophysiology has not been fully elucidated, it can be assumed that a variety of factors are responsible, mainly including traumatic events such as ankle sprains. Advances in arthroscopy and imaging techniques, in particular magnetic resonance imaging (MRI), have improved the possibilities for the diagnosis of OCLs of the ankle. Moreover, these technologies aim at developing new classification systems and modern treatment strategies...

Periprosthetic humerus fractures are relatively uncommon occurrence that can be difficult to manage nonoperatively. Locking plate technology has enhanced the surgical management of these fractures. However, adequate fixation around the stem remains of some concern. We describe an osteosynthesis technique using a locking plate utilizing eccentrically placed screw holes to place "skive screws" in the proximal end of the plate to achieve fixation around the stem of the implant. A clinical series of 5 consecutive patients treated with this technique is presented with an average follow-up of 29 months (range, 12-48)...

Since 'radical lobectomy' was reported by Cahan in 1960, the standard surgical care for lung cancer has been lobectomy, in which units of the lobe are excised with their specific regional hilar and mediastinal lymphatics. However, pulmonary function-preserving limited resection for lung cancer has gradually become more prevalent in the late 20th century. In 1995, Ginsberg et al. conducted a randomized controlled trial in which limited resection (segmentectomy and wide-wedge resection) and lobectomy for stage I lung cancer were compared and reported that limited resection should not be applied to healthy patients with clinical stage IA lung cancer...

Available options for the treatment of advanced heart failure have expanded to include the use of mechanical circulatory assist devices to improve quality of life in those both eligible and ineligible for heart transplant. Although there have been significant advancements in device technologies, anticoagulation protocols, and multidisciplinary team management, bleeding and thrombosis are the most common adverse effects. Management strategies for pump thrombosis and their outcomes vary considerably among mechanical circulatory support centers and include intensification of antithrombotic therapy (medical) and device exchange (surgical)...

The diagnosis of ankle osteoarthritis (OA) is increasing as a result of advancements in non-invasive imaging modalities such as magnetic resonance imaging, improved arthroscopic surgical technology and heightened awareness among clinicians. Unlike OA of the knee, primary or age-related ankle OA is rare, with the majority of ankle OA classified as post-traumatic (PTOA). Ankle trauma, more specifically ankle sprain, is the single most common athletic injury, and no effective therapies are available to prevent or slow progression of PTOA...

The aim of this paper was to evaluate the current technology and designs of flexible ureterorenoscopes. We will review contemporary fiberoptic and digital ureteroscopes, including a discussion on ureteroscope damage and repair, and lastly present the projected future of flexible ureterorenoscopy. Ureterorenoscopy has evolved dramatically over the past several decades, which has led to landscape reshaping of stone disease treatment and upper tract pathology. Advancements in tip control, miniaturization of scopes, introduction of a digital chip on the tip, disposable devices to augment surgery, surgical experience/familiarity and most recently single use scopes are all independent factors that have increased flexible ureterorenoscopy adoption and success...

PURPOSE: Three-tesla intraoperative MRI (iMRI) is a promising tool that could help confirm complete resections and disconnections in pediatric epilepsy surgery, leading to improved outcomes. However, a large proportion of epileptogenic pathologies in children are poorly defined on imaging, which brings into question the utility of iMRI for these cases. Our aim was to compare postoperative seizure outcomes between iMRI- and non-iMRI-based epilepsy surgeries. METHODS: We performed a comparative retrospective analysis of non-iMRI- versus iMRI-based epilepsy surgeries with 2-year follow-up...

The reconstructive ladder and the reconstructive elevator have withstood the test of time as didactic tools for resident education. Over time, many alternative models have been suggested to incorporate the technological advances in plastic surgery, but none of them have focused on the patient. Changes in practice and the trend toward personalized health care demand a 360-degree evaluation and solution of surgical problems incorporating patient-specific characteristics. We, therefore, suggest the concept of the plastic surgery compass to navigate the ladder...
