Purpose: The robotic system for surgery was introduced to gastric cancer surgery in the early 2000s to overcome the shortcomings of laparoscopic surgery. The more recently introduced da Vinci $Xi^{(R)}$ system offers benefits allowing four-quadrant access, greater range of motion, and easier docking through an overhead boom rotation with laser targeting. We aimed to identify whether the $Xi^{(R)}$ system provides actual advantages over the $Si^{(R)}$ system in gastrectomy for gastric cancer by comparing the operative outcomes. Materials and Methods: We retrospectively reviewed all patients who underwent robotic gastrectomy as treatment for gastric cancer from March 2016 to March 2017. Patients' demographic data, perioperative information, and operative and pathological outcomes were collected and analyzed. Results: A total of 109 patients were included in the $Xi^{(R)}$ group and 179 in the $Si^{(R)}$ group. Demographic characteristics were similar in both groups. The mean operative time was 229.9 minutes in the $Xi^{(R)}$ group and 223.7 minutes in the $Si^{(R)}$ group. The mean estimated blood loss was 72.7 mL in the $Xi^{(R)}$ group and 62.1 mL in the $Si^{(R)}$ group. No patient in the $Xi^{(R)}$ group was converted to open or laparoscopy, while 3 patients in the $Si^{(R)}$ group were converted, 2 to open surgery and 1 to laparoscopy, this difference was not statistically significant. Bowel function was resumed 3 days after surgery, while soft diet was initiated 4 days after surgery. Conclusions: We found no difference in surgical outcomes after robotic gastrectomy for gastric cancer between the da Vinci $Xi^{(R)}$ and da Vinci $Si^{(R)}$ procedures.

Background: The conventional transcervical resection for submandibular gland disease has some risks and an unsatisfactory cosmetic result. Recently, robot-assisted surgery has been developed as a plausible substitute for conventional surgery which provides an excellent cosmetic outcome. Case presentation: The authors performed robot-assisted sialadenectomy via modified facelift incision using the da Vinci Xi surgical system (Intuitive Surgical Inc., CA, USA) with two endowrist arms (monopolar curved scissors and Maryland bipolar forceps) successfully in a 44-year-old female patient who suffered from sialolith and severe atrophic submandibular gland. Conclusions: If similar studies are done in the future, this robot-assisted sialadenectomy may become established as an alternative to existing disadvantageous surgical methods.

Currently, robot-assisted latissimus dorsi muscle flap (RLDF) surgery is used in treating patients with Poland syndrome and for breast reconstruction. However, conventional RLDF surgery has several inherent issues. We resolved the existing problems of the conventional system by introducing the da Vinci single-port system in patients with Poland syndrome. Overall, three patients underwent RLDF surgery using the da Vinci single-port system with gas insufflation. In the female patient, after performing RLDF with silicone implant, augmentation mammoplasty was also performed on the contralateral side. Both surgeries were performed as single-port robotic-assisted surgery through the transaxillary approach. The mean operating time was 449 (335-480) minutes; 8.67 (4-14) minutes were required for docking and 59 (52-67) minutes for robotic dissection and LD harvesting. No patients had perioperative complication and postoperative problems related to gas inflation. The single-port robot-assisted surgical system overcomes the drawbacks of previous robotic surgery in patients with Poland syndrome, significantly shortens the procedure time of robotic surgery, has superior cosmetic outcomes in a surgical scar, and improves the operator's convenience. Furthermore, concurrent application to another surgery demonstrates the possibility in the broad application of the robotic single-port surgical system.

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.

Organ preservation surgery and minimally invasive surgery have been developed during the past 20 years with major focus on transoral laser surgery, endoscopic surgery, and robotic surgery. Two major robotic surgeries in head and neck area are transoral robotic surgery (TORS) and robotic thyroidectomy. Transoral robotic surgery is a safe and efficacious method of surgical treatment of oropharyngeal. hypopharyngeal and laryngeal neoplasm. Advantages of the technique include adequate ability to visualize and manipulate lesions with two hands. TORS can provide magnified three dimensional views and overcome the limitation resulting from the "line of sight" which hinders transoral laser procedure. The swallowing function following transoral robotic surgery show superior and patients were able to retain or rapidly regain swallowing function in the majority of cases. Recently, robotic thyroidectomy has also been developed to overcome the [imitation of endoscopic thyroidectomy. Robotic thyroidectomy by a gasless unilateral axillo-breast or axillary approach using a da Vinci S Surgical Robot is a feasible and cosmetically excellent procedure. It can be a promising alternative to endoscopic thyroidectomy or conventional open thyroidectomy.

Background: We report our initial experiences of robot-assisted cardiac surgery using the da Vinci Surgical System. Methods: Between February 2010 and March 2014, 50 consecutive patients underwent minimally invasive robot-assisted cardiac surgery. Results: Robot-assisted cardiac surgery was employed in two cases of minimally invasive direct coronary artery bypass, 17 cases of mitral valve repair, 10 cases of cardiac myxoma removal, 20 cases of atrial septal defect repair, and one isolated CryoMaze procedure. Average cardiopulmonary bypass time and average aorta cross-clamping time were $194.8{\pm}48.6$ minutes and $126.1{\pm}22.6$ minutes in mitral valve repair operations and $132.0{\pm}32.0$ minutes and $76.1{\pm}23.1$ minutes in myxoma removal operations, respectively. During atrial septal defect closure operations, the average cardiopulmonary bypass time was $128.3{\pm}43.1$ minutes. The median length of stay was between five and seven days. The only complication was that one patient needed reoperation to address bleeding. There were no hospital mortalities. Conclusion: Robot-assisted cardiac surgery is safe and effective for mitral valve repair, atrial septal defect closure, and cardiac myxoma removal surgery. Reducing operative time depends heavily on the experience of the entire robotic surgical team.

While simultaneous bilateral partial nephrectomy with a conventional multiport robot has been consistently reported since the 2010s, the introduction of the DaVinci SP system (Intuitive Surgical, Sunnyvale, CA, USA) could provide a novel way to perform surgery on bilateral kidneys while innovatively reducing the number of incisions. In our first report worldwide, the patient with bilateral small renal mass (2.0 cm for the left and 1.5 cm for the right side) and preoperative normal renal function was placed in the lateral decubitus position on an inverted bed. After tilting the bed to be as horizontal as possible, a 4-cm incision was made in the lower part of the umbilicus for the floating trocar technique. The partial nephrectomy was performed reliably as with the conventional transperitoneal approach, and then the patient could be repositioned to the contralateral side for the same procedure, maintaining all trocars. Total operation time (skin to skin), total console time, and the left- and right-side warm ischemic times were 260, 164, 27, and 23 minutes, respectively, without applying the early declamping technique. The estimated blood loss was 200 mL. The serum creatinine right after the operation, on the first day, 3 days, and 90 days after surgery were 0.92, 0.77, 0.79, and 0.81 mg/dL, respectively. For 90 days after the procedure, no complications or radiologic recurrence were observed. Further clinical studies will reveal the advantages of using the DaVinci SP device for this procedure over traditional multiport surgery, maximizing the benefit of a single port-based approach.

MMinimally invasive surgery (MIS) for early stage lung cancer has been an important treatment modality. However, the ergonomic discomfort and counterintuitive instruments hindered the application of video-assisted thoracic surgery (VATS) to more advanced procedures. To improve the compliance with MIS, robotic surgery was adopted. This advance aimed to alleviate the shortcomings of VATS by maximizing the comfort of the surgeon while providing instruments that enabled technically demanding operations and three-dimensional views with increased freedom for intrathoracic movement owing to EndoWrist$^{(R)}$. In this session, we introduced the clinical applications and its results of robot-assisted thoracic surgery in the field of lung cancer surgery. In conclusion, robot-assisted pulmonary resection with lymph node dissection for lung cancer is safe as well as feasible, and it results in a satisfying postoperative outcome. Robot-assisted surgery may provide a good alternative to conventional open or thoracoscopic surgery for lung cancer, provided that the cost effectiveness and long-term prognosis are confirmed.

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.

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.
