Video understanding of robot-assisted surgery (RAS) videos is an active research area. Modeling the gestures and skill level of surgeons presents an interesting problem. The insights drawn may be applied in effective skill acquisition, objective skill assessment, real-time feedback, and human-robot collaborative surgeries. We propose a solution to the tool detection and localization open problem in RAS video understanding, using a strictly computer vision approach and the recent advances of deep learning. We propose an architecture using multimodal convolutional neural networks for fast detection and localization of tools in RAS videos...

INTRODUCTION: As a result of the growing evidence on tumor radical resection in literature, simple enucleation has become one of the best techniques associated to robotic surgery in the treatment of renal neoplasia, as it guarantees minimal invasiveness and the maximum sparing of renal tissue, facilitating the use of reduced or zero ischemia techniques during resection. The use of a robotic ultrasound probe represents a useful tool to detect and define tumor location, especially in poorly exophytic small renal mass...

REVIEW
W Randolph Chitwood
Robotic mitral valve repair began in 1998 and has advanced remarkably. It arose from an interest in reducing patient trauma by operating through smaller incisions with videoscopic assistance. In the United States, following two clinical trials, the FDA approved the daVinci Surgical System in 2002 for intra-cardiac surgery. This device has undergone three iterations, eventuating in the current daVinci XI. At present it is the only robotic device approved for mitral valve surgery. Many larger centers have adopted its use as part of their routine mitral valve repair armamentarium...

Laparoscopic surgery and robotic surgery, two forms of minimally invasive surgery (MIS), have recently experienced a large increase in utilization. Prior studies have shown that video game experience (VGE) may be associated with improved laparoscopic surgery skills; however, similar data supporting a link between VGE and proficiency on a robotic skills simulator (RSS) are lacking. The objective of our study is to determine whether volume or timing of VGE had any impact on RSS performance. Pre-clinical medical students completed a comprehensive questionnaire detailing previous VGE across several time periods...

INTRODUCTION: Robot-assisted surgery emerged and evolved in order to increase the surgical precision and due to the need to overcome the drawbacks of conventional minimally invasive surgery. In thoracic surgery the first reported use of a robotic device was in a series of 12 patients with different lung pathologies with the assistance of the DaVinci Robotic Surgical System in 2002. The DaVinci system has been used for various procedures in the field of thoracic surgery since then. While its advantages for the resection of early stage thymoma have been well documented, its role in the treatment of lung cancer and other pathologies is still under investigation...

REVIEW
M Ashraf, A Souka, R Adelman, S H Forster
The recent results of Protocol T have illustrated the efficacy of aflibercept in the treatment of diabetic macular edema. It also demonstrated that in patients with poor vision (<6/12), aflibercept offers anatomical and visual advantages over ranibizumab and bevacizumab in the first 12 months of treament. At 2 years, the difference between the three drugs decreased with patients with a better baseline VA (69-78) showing a statistically insignificant advantage for ranibizumab compared with aflibercept.These results were achieved using a pro-re nata (PRN) protocol, which was not previously studied in large phase 3 trials, VIVID and VISTA, that chose to compare the 2...

BACKGROUND: Hepatic artery infusion (HAI) chemotherapy is an effective regional therapy for unresectable colorectal liver metastases (U-CRLM).1 (,) 2 One of its limitations is the need for a laparotomy, which can delay the use of systemic therapy.3 Here, we describe a purely robotic technique for placement of an HAI pump (Fig 1). PATIENT: A 62-year-old male presented with a symptomatic ascending colon cancer and multiple bilobar unresectable liver metastases. He underwent laparoscopic right colectomy followed by six cycles of FOLFOXIRI and bevacizumab with stable disease by RECIST (Response Evaluation Criteria in Solid Tumors) criteria, and also underwent robotic HAI pump placement...
