INTRODUCTION: Kidney transplantation (KT) is the preferred treatment for patients with end-stage renal disease (ESRD). To reduce the morbidity of the open surgery, a robotic-assisted approach has been recently introduced. Our aim is to evaluate surgical and functional results on 17 cases of robotic-assisted kidney transplantation (RAKT) performed at the same institution. MATERIALS AND METHODS: From July 2015 to June 2016, we performed 17 cases of RAKT from living donors in pre-emptive patients, who underwent laparoscopic nephrectomy...

Surgery using a robotic system has proven to have significant potential but is still a highly challenging task for the surgeon. An eye surgery assistant has been developed to eliminate the problem of tremor caused by human motions endangering the outcome of ophthalmic surgery. In order to exploit the full potential of the robot and improve the workflow of the surgeon, providing the ability to change control parameters live in the system as well as the ability to connect additional ancillary systems is necessary...

This study aims to develop a robotic hand as a substitute for a surgeon's hand in hand-assisted laparoscopic surgery (HALS). We determined the requirements for the proposed hand from a surgeon's motions in HALS. We identified four basic behaviors: "power grasp," "precision grasp," "open hand for exclusion," and "peace sign for extending peritoneum." The proposed hand had the minimum necessary DOFs for performing these behaviors, five fingers as in a human's hand, a palm that can be folded when a surgeon inserts the hand into the abdomen, and an arm for adjusting the hand's position...

In many complicated cognitive-motor tasks mentoring is inevitable during the learning process. Although mentors are expert in doing the task, trainee's operation might be new for a mentor. This makes mentoring a very difficult task which demands not only the knowledge and experience of a mentor, but also his/her ability to follow trainee's movements and patiently advise him/her during the operation. We hypothesize that information binding throughout the mentor's brain areas, contributed to the task, changes as the expertise level of the trainee improves from novice to intermediate and expert...

In this paper, we propose a new method for detecting hemorrhage areas and surgical instruments in robot-assisted laparoscopic surgery images. The proposed scheme utilizes CIELAB information to identify a region of interest (ROI) and segment it. Histogram equalization and Otsu's method are also adopted to compute the detection threshold. Detection is performed automatically and additional adjustment of parameters is not needed. Experiments to verify the proposed algorithm were conducted using actual robot-assisted laparoscopic surgery images...

Minimally invasive surgery can be performed with robotic assistance, as evolution of laparoscopic surgery. Robots for assisted surgery are far from being user friendly and require extensive training. To this end, ad-hoc devices and experimental set-ups are needed. The da Vinci system is one of the most diffused surgical robotics technology. The aim of the study was two-fold: i) to propose a neurophysiological measure by which objectively assess the learning progress of the users by means of a simulator of the da Vinci system, and ii) to demonstrate the advantages of cognitive assessment with respect to the standard methodologies for the evaluation of training efficiency...

BACKGROUND AND AIMS: Although volume controlled ventilation (VCV) has been the traditional mode of ventilation in robotic surgery, recently pressure controlled ventilation (PCV) has been used more frequently. However, evidence on whether PCV is superior to VCV is still lacking. We intended to compare the effects of VCV and PCV on respiratory mechanics and haemodynamic in patients undergoing robotic surgeries in steep Trendelenburg position. METHODS: This prospective, randomized trial was conducted on sixty patients between 20 and 70 years belonging to the American Society of Anesthesiologist Physical Status I-II...

BACKGROUND: To limit the potential short and long-term morbidity of lymphadenectomy, sentinel lymph node (SLN) biopsy has been proposed for endometrial cancer. The principle of SLN biopsy relies on removal of a small number of lymph nodes that are the first drainage basins from a tumor and thus the most likely to harbor tumor cells. While the procedure may reduce morbidity, efficacy data is limited and little is known about how commonly the procedure is performed. OBJECTIVE: We examined the patterns and predictors of use of SLN biopsy and outcomes of the procedure in women with endometrial cancer who underwent hysterectomy...

The robotic approach to cardiac surgery offers patients numerous potential advantages compared with a traditional sternotomy approach including shorter hospital length of stay, reduced pain, fewer blood transfusions, and a quicker return to normal daily activities. At the same time, robotic cardiac surgery requires that the anesthesiologist employs several subspecialty skillsets in order to provide optimal care for these patients. Multiple different regional anesthesia techniques may be used to improve analgesia, reduce opioid dosages, and facilitate rapid extubation at the conclusion of the case...

Double-sleeve lobectomy, which includes bronchoplasty and pulmonary arterial angioplasty, is required for certain cases of central-type lung cancer. It is usually done by open surgery or video-assisted thoracoscopic surgery (VATS). In recently, da Vinci system and robotic surgery have been applied in such complicated cases. Here we describe the details associated with robotic-assisted double-sleeve lobectomy.

Robotic surgery is a conceptual fusion of the conventional open surgery and the minimally invasive laparoscopic surgery. We reviewed the current role of robotic-assisted laparoscopy in the field of reproductive surgery by a literature search in PubMed database. We analyzed the reported advantages and limitations of the use of robotics in reproductive surgeries like myomectomy, tubal reanastomosis, endometriosis, ovarian tissue cryopreservation, and ovarian transposition. Overall, robotic assistance in reproductive surgery resulted in decreased blood loss, less post-operative pain, shorter hospital stay, and faster convalescence, whereas reproductive outcomes were similar to open/laparoscopic approaches...

Robotic-assisted surgery is a technological advancement derived from conventional laparoscopy, which facilitates the application of minimally invasive techniques for complex operations in the field of gynecological oncology. However, its introduction in gynecological cancer has been scarce in most hospitals worldwide. Most publications on robotic surgery are still retrospective or descriptive in nature. Some studies compare robotic-assisted laparoscopy with open procedures, which is a questionable analysis, because the advantages of minimally invasive surgery have been already well established...

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...
