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
ObjectiveTo summarize the research progress of peripheral nerve surgery assisted by Da Vinci robotic system. MethodsThe recent domestic and international articles about peripheral nerve surgery assisted by Da Vinci robotic system were reviewed and summarized. ResultsCompared with conventional microsurgery, peripheral nerve surgery assisted by Da Vinci robotic system has distinctive advantages, such as elimination of physiological tremors and three-dimensional high-resolution vision. It is possible to perform robot assisted limb nerve surgery using either the traditional brachial plexus approach or the mini-invasive approach. ConclusionThe development of Da Vinci robotic system has revealed new perspectives in peripheral nerve surgery. But it has still been at the initial stage, more basic and clinical researches are still needed.
ObjectiveTo investigate the effect of pressure control ventilation-volume guaranteed (PCV-VG) for patients undergoing da Vinci robotic-assisted pulmonary lobotomy. MethodA total of 40 patients undergoing Da Vinci robotic-assisted pulmonary lobotomy were randomly divided into two groups:a PCV-VG group (G group) and a volume-controlled ventilation (VCV) group (V group). There were 20 patients in each group with 13 males and 7 females at age of 49.0±5.5 years in the G group, 16 males and 4 females at age of 51.0±3.9 years in the V group. Haemodynamics indexes and oxygenation parameters were recorded at different times and compared between the two groups. ResultsDuring one-lung ventilation (OLV) period, the peak inspiratory pressure (Ppeak), respiratory index (RI) and arterial partial pressure of carbon dioxide (PaCO2) in the G group were statistically lower than those in the V group (P<0.05). While the Cdyn and inspired oxygen fraction(OI) were higher in the G group than those in the V group (P<0.05). ConclusionCompared with the traditional VCV ventilation mode, the PCV-VG ventilation mode improves Ppeak, Cdyn, OI, and RI of the patients undergoing da Vinci robotic-assisted pulmonary lobotomy.
ObjectiveTo estimate postoperative pain and use of analgesic of patients who underwent video-assisted thoracoscopic surgery(VATS) or robotic assisted thoracoscopic surgery(RATS). MethodsFrom October 2014 through August 2015, 339 patients were treated by surgery in Shanghai Chest Hospital. Among them, 116 patients with intrathoracic lesions who underwent RATS with the da Vinci? Surgical System were as a RATS group with 51 males and 65 females at age of 52.59±11.49 years. Another 223 patients by VATS were as a VATS group with 93 males and 130 females at age of 58.00±10.56 years. We recorded the data of the VAS score and use analgesic of the patients after surgery. ResultsThere was a significant difference in VAS score between the RATS group and the VATS group(3.01±0.18 vs. 5.19±0.14, P<0.05). Astatistical difference of analgesic use between RATS and VATS was also found(1.09±0.12 vs. 1.77±0.10, P<0.05). ConclusionCompared with VATS, the postoperative pain of the patients who underwent RATS is lighter. And the use of analgesic is less.
