EDITORIAL
Zenichi Morise
Laparoscopic liver resection (LLR) for tumors in the posterosuperior liver [segment (S) 7 and deep S6] is a challenging clinical procedure. This area is located in the bottom of the small subphrenic space (rib cage), with the large and heavy right liver on it when the patient is in the supine position. Thus, LLR of this area is technically demanding because of the handling of the right liver which is necessary to obtain a fine surgical view, secure hemostasis and conduct the resection so as to achieve an appropriate surgical margin in the cage...

PURPOSE: Robotics in surgery is a recent innovation. This technology offers a number of attractive features in laparoscopy. It overcomes the difficulties with fixed port sites by restoring all 6 degrees of freedom at the instrument tips, provides new possibilities for miniaturization of surgical tasks and allows remote controlled surgery. We investigated the applicability of remote controlled robotic surgery to laparoscopic radical prostatectomy. MATERIALS AND METHODS: Our previous experience with laparoscopic prostatectomy served as a basis for adapting robotic surgery to this procedure...

Glucocorticoid hormones (cortisol and corticosterone - CORT) are the effector hormones of the hypothalamic-pituitary-adrenal (HPA) axis neuroendocrine system. CORT is a systemic intercellular signal whose level predictably varies with time of day and dynamically increases with environmental and psychological stressors. This hormonal signal is utilized by virtually every cell and physiological system of the body to optimize performance according to circadian, environmental and physiological demands. Disturbances in normal HPA axis activity profiles are associated with a wide variety of physiological and mental health disorders...

In recent years, tremendous progress has been made in surgical practice for example with Minimally Invasive Surgery (MIS). To overcome challenges coming from deported eye-to-hand manipulation, robotic and computer-assisted systems have been developed. Having real-time knowledge of the pose of surgical tools with respect to the surgical camera and underlying anatomy is a key ingredient for such systems. In this paper, we present a review of the literature dealing with vision-based and marker-less surgical tool detection...

The liver is a vascular-rich solid organ. Safe and effective dissection of the vessels and liver parenchyma, and control of intraoperative bleeding are the main concerns when performing liver resection. Several studies have confirmed that intraoperative blood loss and postoperative transfusion are predictors of postoperative morbidity and mortality in liver surgery. Various methods and instruments have been developed during hepatectomy. Stapling devices are crucial for safe and rapid anastomosis. They are used to divide hepatic veins and portal branches, and to transect liver parenchyma in open liver resection...

OBJECTIVE Rigid endoscopes enable minimally invasive access to the ventricular system; however, the operative field is limited to the instrument tip, necessitating rotation of the entire instrument and causing consequent tissue compression while reaching around corners. Although flexible endoscopes offer tip steerability to address this limitation, they are more difficult to control and provide fewer and smaller working channels. A middle ground between these instruments-a rigid endoscope that possesses multiple instrument ports (for example, one at the tip and one on the side)-is proposed in this article, and a prototype device is evaluated in the context of a third ventricular colloid cyst resection combined with septostomy...

Kyunghwa Jung, Hyunseok Choi, Hanpyo Hong, Arnold Adikrishna, In-Ho Jeon, Jaesung Hong
BACKGROUND: A hands-free region-of-interest (ROI) selection interface is proposed for solo surgery using a wide-angle endoscope. A wide-angle endoscope provides images with a larger field of view than a conventional endoscope. With an appropriate selection interface for a ROI, surgeons can also obtain a detailed local view as if they moved a conventional endoscope in a specific position and direction. METHODS: To manipulate the endoscope without releasing the surgical instrument in hand, a mini-camera is attached to the instrument, and the images taken by the attached camera are analyzed...

OBJECTIVES/HYPOTHESIS: Transoral surgery (TOS) is commonly performed in a supine patient with an oral retractor. Paradoxically, this strategy can create difficulty with visualizing and accessing pathology at the base of tongue, inferior pharynx, and larynx. We investigate the feasibility of TOS with the patient in the seated position. STUDY DESIGN: Pilot study. METHODS: TOS utilizing the da Vinci Robotic Surgical Xi and Si systems (Intuitive Surgical, Sunnyvale, CA) was performed on a fresh cadaver placed in both the traditional supine position and the seated position...

In the past 10 years, laparoscopy has been challenged by robotic surgery; nevertheless, laparoscopic techniques are subject to continuous change. Ultrahigh definition is the next development in video technology, it delivers fourfold more detail than full high definition resulting in improved fine detail, increased texture, and an almost photographic emulsion of smoothness of the image. New 4K ultrahigh-definition technology might remove the current need for the use of polarized glasses. New devices for laparoscopy include advanced sealing devices, instruments with six degrees of freedom, ergonomic platforms with armrests and a chest support, and camera holders...

BACKGROUND: Robot-assisted laparoscopic surgery offers several advantages compared with open surgery and conventional minimally invasive surgery. However, one issue that needs to be resolved is a collision between the robot arm and the assistant instrument. This is mostly caused by miscommunication between the surgeon and the assistant. To resolve this limitation, an assistant surgical robot system that can be simultaneously manipulated via a wireless controller is proposed to allow the surgeon to control the assistant instrument...

The idea of reproducing himself with the use of a mechanical robot structure has been in man's imagination in the last 3000 years. However, the use of robots in medicine has only 30 years of history. The application of robots in surgery originates from the need of modern man to achieve two goals: the telepresence and the performance of repetitive and accurate tasks. The first "robot surgeon" used on a human patient was the PUMA 200 in 1985. In the 1990s, scientists developed the concept of "master-slave" robot, which consisted of a robot with remote manipulators controlled by a surgeon at a surgical workstation...

Laparoscopic surgery has become a widely performed surgery as it is one of the most common minimally invasive surgeries. Doctors perform the surgery by manipulating thin and long surgical instruments precisely with the assistance of laparoscopic video with limited field of view. The power control of the instruments' tip is especially very important, because excessive power may damage internal organs. The training of this surgical technique is mainly supervised by an expert in hands-on coaching program. However, it is difficult for the experts to spend sufficient time for coaching...
