Purpose: We evaluated the learning curve and short-term surgical outcomes of robot-assisted distal gastrectomy (RADG) performed by a single surgeon experienced in open, but not laparoscopic, gastrectomy. We aimed to verify the feasibility of performing RADG without extensive laparoscopic experience. Materials and Methods: Between July 2012 and December 2016, 60 RADG procedures were performed by a single surgeon using the da $Vinci^{(R)}$ Surgical System (Intuitive Surgical). Patient characteristics, the length of the learning curve, surgical parameters, and short-term postoperative outcomes were analyzed and compared before and after the learning curve had been overcome. Results: The duration of surgery rapidly decreased from the first to the fourth case; after 25 procedures, the duration of surgery was stabilized, suggesting that the learning curve had been overcome. Cases were divided into 2 groups: 25 cases before the learning curve had been overcome (early cases) and 35 later cases. The mean duration of surgery was 420.8 minutes for the initial cases and 281.7 minutes for the later cases (P<0.001). The console time was significantly shorter during the later cases (168.6 minutes) than during the early cases (247.1 minutes) (P<0.001). Although the volume of blood loss during surgery declined over time, there was no significant difference between the early and later cases. No other postoperative outcomes differed between the 2 groups. Pathology reports revealed the presence of mucosal invasion in 58 patients and submucosal invasion in 2 patients. Conclusions: RADG can be performed safely with acceptable surgical outcomes by experts in open gastrectomy.

In orthopedics, hip arthroplasty is the operation that replaces damaged hip joint to artificial joint. In hip arthroplasty, quite better result can be achieved if robot is applied to machine cavity in bone, especially when cementless stem is used. So several kinds of robots were introduced for hip arthroplasty, but they used MRI, CT Scan, vision analysis and real time tracking of bone position for registration of robot. To overcome shortage of conventional robot surgery, gauge based registration method was proposed and small robot was designed. In this method, small robot is mounted on femur, and its position is determined by gauge registration method. Operation procedure was performed on model femur and result was analyzed. This robotic hip surgery system is expected to more adaptable in operation room.

Minimally invasive esophagectomy (MIE) was first introduced in the 1990s. Currently, it is a widely accepted surgical approach for the treatment of esophageal cancer, as it is an oncologically sound procedure; its advantages when compared to open procedures, including reduction in postoperative complications, reduction in the length of hospital stay, and improvement in quality of life, are well documented. However, debates are still ongoing about the safety and efficacy of MIE. The present review focuses on some of the current issues related to conventional MIE and robot-assisted MIE based on evidence from the current literature.

Robotically assisted mitral valve repair has proven its efficacy during the last decade. The most suitable approach for patients with difficult anatomies, such as morbid obesity, sternal deformities, cardiac rotation, or vascular anomalies, represents a current challenge in cardiac surgery. Herein, we present the case of a 71-year-old patient affected by severe degenerative mitral valve regurgitation with pectus excavatum and a right aortic arch with an anomalous course of the left subclavian artery who was successfully treated using a Da Vinci-assisted approach.

Pneumoperitoneum usually presents as a surgical emergency, especially in patients with a history of trauma. However, we recently encountered an atypical case of pneumoperitoneum at a hysterectomy site following blunt trauma, indicating that immediate laparotomy may not always be necessary. In this report, we present the case of a 45-year-old woman who was transferred to our trauma center from a local hospital after being involved in a traffic accident the day before. Although she underwent an emergency laparotomy, no bowel perforation was detected. Instead, a rupture was found at the site of a hysterectomy that had been performed 8 months earlier. After repairing the hysterectomy site, the pneumoperitoneum resolved, and the patient was subsequently discharged without further complications.

This study was attempted to predict the direction for ward nursing work through robotic systemization. Robot systems have not been universalized due to difficulties in operation, space constraints, and high prices. The robotic systemization should be focused on the robotic systemization of simple and repetitive tasks. The idea of a robot system for measuring vital signs and a robot system that helps bed sheet exchange is worth discussing with the engineering field. In addition, for successful nursing and interdisciplinary convergence, a detailed analysis of nursing work is required, and in order to overcome the trial and error of convergence, it is necessary to establish a converging society between nursing and interdisciplinary systems. Robotic systemization of successful ward nursing work will not only generate profits for hospitals, but also raise the status of nurses and will be the starting point for innovation in nursing work.

The deep inferior epigastric perforator (DIEP) flap has been widely used for autologous breast reconstruction after mastectomy. In the conventional surgical method, a long incision is needed at the anterior fascia of the rectus abdominis muscle to obtain sufficient pedicle length; this may increase the risk of incisional hernia. To shorten the incision, several trials have investigated the use of endoscopic/robotic devices for pedicle harvest; however, making multiple additional incisions for port insertion and operating in the intraperitoneal field were inevitable. Here, we describe the first case, in which a DIEP free flap was successfully made using the da Vinci SP model. Our findings can help surgeons perform operations in smaller fields with a single port in the extraperitoneal space. Moreover, this method is expected to lead to fewer donor-related complications and faster healing.

The da Vinci telemanipulator system (Intuitive Surgical, Sunnyvale, CA USA) is the most advanced robotic surgical system and has been increasingly used for cardiac surgical procedures. We report out first clinical experience of use of the da Vinci telemanipulator system for endoscopic harvesting of the bilateral thoracic artery andmulti-vessel small thoracotomy off pump CABG for 3-vessel disease. The da Vinci telemanipulator system has been previously utilized primarily for mitral valve surgery.

The purpose of this study was to know the difference in pain, sleep, self-care behavior in patients performed by sternotomy and robotic minimally invasive cardiac surgeries. The participants were 64 patients with sternotomy and 64 patients with minimal thoracotomy in heart valve surgeries at a tertiary hospital in Seoul. Data were analyzed using descriptive statistics, ${\chi}^2$ test, paired t-test. with SPSS/WIN(22.0). The participants with minimally invasive thoracotomy felt severe pain than the patients with thoracotomy at post operation day 2 & 5. The severe pain site were the surgical site in both groups. The participants with sternotomy had better sleep than minimally invasive thoracotomy patients. Self-care behavior was higher in the minimally invasive thoracotomy group. Therefore, despite the many advantages of robotic surgery such as rapid recovery and shortening of length of stay in hospital, accurate pain assessment and application of differentiated protocols are needed for the management of pain in the patients with robotic minimally invasive cardiac surgeries. In addition, a structured education program intervention is needed to improve comfort by considering gender, age, and method of operation.

Classic anesthetic techniques for the inferior alveolar nerve, lingual nerve, and long buccal nerve blockade are achieved by estimating the intended location for anesthetic deposition based on palpation, inspection, and subsequent correlation for oral anatomical structures. The present article utilizes computed tomography (CT) data to 3D print a guide for repeatable and accurate deposition of a local anesthetic at the ideal location. This technical report aims to anatomically define the ideal location for local anesthetic deposition. This process has the potential to reduce patient discomfort, risk of nerve damage, and failed mandibular anesthesia, as well as to reduce the total anesthetic dose. Lastly, as robotic-based interventions improve, this provides the initial framework for robot-guided regional anesthesia administration in the oral cavity.
