Robot-assisted surgery is evolving to incorporate a higher number of minimally invasive techniques. There is a growing interest in robotic breast reconstruction that uses autologous tissue. Since a traditional latissimus dorsi (LD) flap leads to a long donor scar, which can be an unpleasant burden to patients, there have been many attempts to decrease the scar length using minimally invasive approaches. This study presents the case of a patient who underwent a robot-assisted nipple-sparing mastectomy followed by immediate breast reconstruction with an LD flap using a single-port robotic surgery system. With the assistance of a single-port robot, a simple docking process using a short and less visible incision is possible. Compared to multiport surgery systems, single-port robots can reduce the possibility of collision between robotic arms and provide a clear view of the medial border of the LD where the curvature of the back restricts the visual field. We recommend the use of single-port robots as a minimally invasive approach for harvesting LD flaps.

Objectives: The purpose of this study is to report two cases of prostate cancer patients whose side effects after surgery were treated with traditional Korean medicine. Methods: Two prostate cancer patients underwent robot-assisted laparoscopic prostatectomy, and both patients were treated with traditional Korean medicine. Subjective discomfort symptoms were evaluated using the Numerical Rating Scale. Adverse events were evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events, version 5.0. Daily life vitality was evaluated by the Eastern Cooperative Oncology Group. Results: After treatment with traditional Korean medicine, discomfort symptoms that occurred after surgery, such as frequent urination, nocturia, insomnia, and depression, all gradually improved, and Eastern Cooperative Oncology Group scores also improved from two points to one point. Additionally, there were no hematologic side effects from the traditional Korean medicine treatment. Conclusions: This case study suggests that traditional Korean medicine may contribute to the improvement of side effects caused by robot-assisted laparoscopic prostatectomy, quality of life, and immunity.

Objective : In the field of spinal surgery, a few laboratory results or clinical cases about robotic spinal surgery have been reported. In vivo trials and development of related surgical instruments for spinal surgery are required before its clinical application. We investigated the use of the da $Vinci^{(R)}$ Surgical System in spinal surgery at the craniovertebral junction in a human cadaver to demonstrate the efficacy and pitfalls of robotic surgery. Methods : Dissection of pharyngeal wall to the exposure of C1 and odontoid process was performed with full robotic procedure. Although assistance of another surgeon was necessary for drilling and removal of odontoid process due to the lack of appropriate end-effectors, successful robotic procedures for dural sutures and exposing spinal cord proved its safety and dexterity. Results : Robot-assisted odontoidectomy was successfully performed in a human cadaver using the da $Vinci^{(R)}$ Surgical System with few robotic arm collisions and minimal soft tissue damages. Da $Vinci^{(R)}$ Surgical System manifested more dexterous movement than human hands in the deep and narrow oral cavity. Furthermore, sutures with robotic procedure in the oral cavity demonstrated the advantage over conventional procedure. Conclusion : Presenting cadaveric study proved the probability of robot-assisted transoral approach. However, the development of robotic instruments specific to spinal surgery must first precede its clinical application.

Video-assisted pulmonary lobectomy was introduced in the early 1990's by several authors, and the frequency of video-assisted thoracic surgery (VATS) lobectomy for lung cancer has been slowly increasing because of its safety and oncologic acceptability in patients with early stage lung cancer However, VATS is limited by 2D imaging, an unsteady camera platform, and limited maneuverability of its instruments. The da Vinci Surgical System was recently introduced to overcome these limitations. It has a 3D endoscopic system with high resolution and magnified binocular views and EndoWrist instruments. We report three cases of da Vinci robot system-assisted pulmonary lobectomy in patients with early stage lung cancer.

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.

The postoperative respiratory complications such as pneumonia and ARDS, are poor prognostic factors after esophagectomy in patients with esophageal cancer. To avoid these complications, there have been attempts to use minimally invasive approach. Recently introduced daVinciTM S surgical system is used in esophagectomy because of its advantages of minimal invasiveness, clear 3-dimensional imaging and precise handling of robotic arms. We report a 83-year-old esophageal cancer patient who underwent daVinciTMS robot-assisted esophagectomy, laparoscopic stomach mobilization followed by cervical esophagogastrostomy.

Recently, robots have been used in surgical area. Robotic surgery in Minimally Invasive Surgery gives many advantages to surgeons and patients both. This study introduce a robotic assistant to improve the safety of telerobotic Minimally Invasive Surgical procedures. The master-slave system is applied to the telerobotic surgical system with the master arm, which control the system, and slave robot which operates the surgery on the patient body. By using a 3-DOF master arm, the surgeon can control the 6-DOF surgical robot under the constraint of fulcrum point. This paper explains the telerobotic surgical system and confirms the system with the precision of the robot control related to the fulcrum point to enhance the safety.

Although laparoscopic surgery for hepatobiliary disease in children is possible, it is technically challenging. In an attempt to overcome these difficulties, the da Vinci Robotic Surgical System$^{(R)}$ was used to facilitate the minimally invasive treatment of choledochal Cyst in six children. In early consecutive three cases, we experienced three complications; a case of laparotomy conversion, a case of late stenosis of the hepaticojejunostomy, and a case of leakage from a hepaticojejunostomy. However, in the last three cases the complete resection of the choledochal cyst and Roux-en-Y hepaticojejunostomy were performed using the robotic surgical system without complication. We think robot-assisted choledochal cyst resection in children appears safe and feasible, and may increase the variety of complex procedures in pediatric surgical fields.

Robotic surgery have been increasingly applied in the past several years to assist in a variety of operations. Some applications, such as in prostatectomy, have been widely adopted and have largely supplanted the alternative minimally invasive or open techniques. However, the use of surgical robots in esophagectomy has not been as common. Although a limited number of case reports demonstrated the feasibility of robotic esophagectomy, no large series of patients has been reported to date. The data on robotic-assisted esophagectomy suggest that the procedure is safe, feasible, and associated with perioperative outcomes similar to open and minimally invasive esophagectomy. Benefits of robotic system could be maximized when we do a extensive total mediastinal lymphadenectomy. For this procedure to gain widespread acceptance, identifiable benefit relative should be demonstrated in near future.

In the treatment of myasthenia gravis, thymectomy is generally accepted as the standard of therapy. For thymectomy, there have been various conventional open approaches including sternal splitting, but recently minimally invasive approaches have been increasingly applied. A 28-year-old man presenting with weakness of both hands and fatigability was diagnosed as having myasthenia gravis with thymic hyperplasia. He underwent a robot-assisted thymectomy with the 'da Vinci' surgical system. Through the right thoracic cavity, two thirds of the thymic gland was dissected, and the remainder was resected through the left; these procedures took, respectively, 1 hour and 30 minutes. The patient was discharged on the 8th postoperative day without complications. The minimally invasive approach with the 'da Vinci' surgical system is emerging as a popular choice and various advantages have been reported. Here we report the first successful case of robot-assisted thymectomy.
