Objective To summary the early experience of Dixon procedures with Da Vinci robotics surgical system for rectal cancer. Methods Eleven patients with rectal cancer underwent the combination of laparoscope and Da Vinci robotics surgical system with 4 trocars in our hospital from May. 2011 to Jan. 2012. Laparoscopy was firstly used to identify the possibility of the surgical procedure， then placed the 4 trocars， and maked sure the suspension of the sigmoid colon and the uterus. Transections of rectum were performed by a conventional laparoscopic method， and endoscopic separations were performed by Da Vinci robotics surgical system. The clinical data were retrospectively analyzed and the experience was summarized. Results The Da Vinci robotics-assisted Dixon procedures were successfully performed in 11 patients and no one turned to laparotomy. The operating time was 210-330min （mean 288.6min）；the blood loss was 20-100ml （mean 40ml）； The number of lymph nodes dissected was 12-21 per case （mean 13.9 per case）；the duration of bowel movement and hospital stay were 18-26h （mean 22h） and 7-16d （mean 11.5d）， respectively. There were no intraoperative or postoperative complications related to the use of robotics， and no residual cancer cells at resection margin. Conclusions Da Vinci robotics-assisted Dixion procedure with 4 trocars and suspension of sigmoid colon are safe and feasible， and it is beneficial to the recovery of patients
Objective To summarize the computer assisted navigation and robotics in the classification of knee surgery, and the development, surgical indications and contraindication, effectiveness, and the research progress of computer assisted navigation and robotics in unicompartmental knee arthroplasty (UKA). Methods The related literature on computer assisted navigation and robotics in UKA was extensively reviewed, summarized, and analyzed. Results Recently, satisfactory results have been achieved in UKA for the treatment of single compartmental knee osteoarthritis. With the rapid development of computer navigation and robotic technology gradually combined with clinical practice, the great precision and accuracy of implant have been improved in computer navigation and robotics in UKA surgery. Postoperative function is well recovered, meanwhile, prosthesis survival can be significantly increased. Conclusion Computer assisted navigation and robotics in UKA can greatly improve the accuracy of the implant when compared with traditional UKA. The early effectiveness is satisfactory, but the long-term effectiveness still needs to be further observed.
Nowadays, thoracoscopic laparoscopic esophagectomy (TLE) has been widely used in the treatment of esophageal cancer. In recent years, robot assisted minimally invasive esophagectomy (RAMIE) has been developing vigorously. According to the research progress and practical experience in the world, RAMIE has the same safety and effectiveness as TLE. In this paper, several aspects on this novel operation were demonstrated, including the safety evaluation, lymph node dissection, prognosis of RAMIE, comparison of RAMIE and TLE, and the role of RAMIE in multidisciplinary treatment of esophageal cancer, in order to promote the rational application of RAMIE in esophagectomy.
ObjectiveTo evaluate the short-term effectiveness of robotic distal pancreatectomy (RDP) and laparoscopic distal pancreatectomy (LDP) by meta-analysis.MethodsWe searched for manuscripts about RDP versus LDP form PubMed, The Cochrane Library, EMbase, CKNI, CBM, and WanFang Databases. The parallel quality assessment was selected according to the literature inclusion and exclusion criteria. Relevant data were extracted and meta-analysis was performed by using Revman 5.3 software.ResultsA total of 23 articles were included, and a total of3 487 patients enrolled who underwent pancreatic body resection. Meta-analysis results showed that compared with the LDP group, the RDP group had a longer operation time [MD=15.52, 95%CI was (0.60, 30.45), P=0.04], but the intraoperative blood loss was less [MD=–59.18, 95%CI was (–111.62, –6.73), P=0.03], the intraoperative spleen preservation rate was higher [OR=1.74, 95%CI was (1.02, 2.96), P=0.04], the intraoperative conversion to open rate was lower [ OR=0.45, 95%CI was (0.34, 0.60), P<0.000 01], and postoperative hospital stay was shorter [MD=–0.90, 95%CI was (–1.70, –0.10), P=0.03], while there were no significant differences in intraoperative blood transfusion rate [OR=0.88, 95%CI was (0.60, 1.30), P=0.52], incidence of postoperative overall complication [OR=0.88, 95%CI was (0.68, 1.13), P=0.32] and pancreatic leakage [OR=0.91, 95%CI was (0.72, 1.14), P=0.41], 90-day readmission rate [OR=1.32, 95%CI was (0.95, 1.83), P=0.10], and 90-day reoperation rate [OR=0.73, 95%CI was (0.40, 1.33), P=0.30].ConclusionsRDP has the advantages of less bleeding, low turnover rate, and short postoperative hospital stay. However, due to the quality limitations of the included studies, the above conclusions still need to be verified by more high-quality studies.
Spinal robotics has rounded out twenty years in clinical, is mainly used for pedicle screw placement at present, can significantly increase the accuracy of screw placement and reduce radiation exposure to the patient and the surgeon. In the future, haptic feedback, automatic collision avoidance, and other technologies will further expand its application to complete precise operations such as decompression and correction, providing safety guarantee for the implementation of complex spinal surgery.
