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 investigate the role of laparoscopic pancreaticoduodenectomy (LPD) for periampullary carcinoma. MethodsThis is a retrospective review of all periampullary carcinomas consecutively performed between January 2013 and January 2016 in Zhejiang Provincial People's Hospital. ResultsFifty-one patients underwent LPD. Conversion to open procedure was required in three cases. The operative time was (370±104) min, The estimated blood loss was (220.7±180.9) mL. Five cases had binding pancreaticogastric anastomosis, the other patients underwent duct to mucosa pancreaticojejunal anastomosis. Post operatively hospital stay was (14.6±11.2) days. The represented morbidity including pancreatic fistula (9 cases), postoperative intraperitoneal bleeding (2 cases), postoperative gastrointestinal bleeding (2 cases), delayed gastric emptying (4 cases), and bile leakage (4 cases). All patients underwent R0 resection. Postoperative pathological results: pancreatic adenocarcinoma: 28 cases, duodenal papillary adenocarcinoma: 12 cases, common bile duct adenocarcinoma: 11 cases. Conciusions LPD has been proven to be a safe procedure. Our LPD approach can improve the effectiveness of lymphadenectomy. It combined with resection of portal vein can improve the R0 resection rate of periampullary adenocarcinoma and is associated with better survival of those patients.

ObjectiveTo evaluate the feasibility and safety of da Vinci robotic surgery for elderly patients with pulmonary lobectomy. MethodsWe retrospectively analyzed the clinical data of 50 patients in General Hospital of Shenyang Military Region of Thoracic Surgery between May 2012 and March 2015.The patients were divided into two groups. Twenty five patients aged over 70 years underwent radical operation of lung cancer with da Vinci Robot System were allocated into a robot group with 17 males and 8 females at age of 72.6 ±2.5 years. Another 25 senile patients with radical surgery by video-assisted thoracoscopic surgery (VATS) were allocated into a thoracoscopic group with 17 males and 8 females at age of 72.5±2.4 years. The patients in the two groups underwent pulmonary lobectomy and mediastinal lymph node dissection. The clinical effect of the two groups was compared. ResultsAll patients were diagnosed as lung cancer. Twenty five patients all completed surgery under da Vinci Robot System in the robot group. In the thoracoscopic group, one patient was converted to thoracotomy. There were statistical differences in amount of blood loss (66.2±44.2 ml vs. 356.0±349.2 ml, P=0.000), lymph node number (23.2±9.8 vs. 11.3±5.6, P=0.012), and postoperative bed time (3.5±0.9 d vs. 4.2±1.1 d, P=0.017) between the two groups. Effect in the robot group was superior to that in the thoracoscopic group. ConclusionDa Vinci robotic surgery system for elderly patients with lung cancer radical surgery is safe, effective, and less thoracoscopic surgery trauma, recovery faster.
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.
ObjectiveTo systematically review the efficacy and safety of robotic-assisted thoracic surgery (RATS) and video assisted thoracic surgery (VATS) for patients with non-small cell lung cancer (NSCLC). MethodsWe searched PubMed, EMbase, The Cochrane Library (Issue 9, 2016), Web of Science, CNKI, VIP, WanFang Data and CBM databases to collect clinical studies about RATS vs. VATS for patients with NSCLC from inception to October 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 14 cohort studies involving 19 921 patients were included; among them, 4 322 cases were in the RATS group, and 15 599 were in the VATS group. The results of meta-analysis showed that the operation time (MD=22.90, 95%CI 9.97 to 35.84, P<0.000 5) was longer in the RATS group than the VATS group. However, the conversion rate (OR=0.72, 95%CI 0.44 to 1.18, P=0.20), the incidence of postoperative complications (OR=1.06, 95%CI 0.96 to 1.17, P=0.28), intraoperative blood loss (MD=2.75, 95%CI –8.39 to 13.89, P=0.63), postoperative hospitalization time (MD=–0.00, 95%CI –0.02 to 0.02, P=0.99) and in-hospital mortality rate (OR=0.60, 95%CI 0.35 to 1.05, P=0.07) were not significant differences between both groups.ConclusionThe current meta-analysis indicates that the efficacy and safety of RATS and VATS for NSCLC is equivalence, however the operation time for RATS is longer. Due to the limited quantity and quality of inclued studies, the above conclusions still need to be verified by more high quality studies.
ObjectiveTo summarize the experience of minimally invasive anterior mediastinal tumor resection in our center, and compare the Da Vinci robotic and video-assisted thoracoscopic approaches in the treatment of mediastinal tumor.MethodsA retrospective cohort study was conducted to continuously enroll 102 patients who underwent minimally invasive mediastinal tumor resection between September 2014 and November 2019 by the single medical group in our department. They were divided into two groups: a robotic group (n=47, 23 males and 24 females, average age of 52 years) and a thoracoscopic group (n=55, 29 males and 26 females, average age of 53 years). The operation time, intraoperative blood loss, postoperative thoracic drainage volume, postoperative thoracic drainage time, postoperative hospital stay, hospitalization expense and other clinical data of two groups were compared and analyzed.ResultsAll the patients successfully completed the surgery and recovered from hospital, with no perioperative death. Myasthenia gravis occurred in 4 patients of the robotic group and 5 of the thoracoscopic group. The tumor size was 2.5 (0.8-8.7) cm in the robotic group and 3.0 (0.8-7.7) cm in the thoracoscopic group. Operation time was 62 (30-132) min in the robotic group and 60 (29-118) min in the thoracoscopic group. Intraoperative bleeding volume was 20 (2-50) mL in the robotic group and 20 (5-100) mL in the thoracoscopic group. The postoperative drainage volume was 240 (20-14 130) mL in the robotic group and 295 (20-1 070) mL in the thoracoscopic group. The postoperative drainage time was 2 (1-15) days in the robotic group and 2 (1-5) days in the thoracoscopic group. There was no significant difference between the two groups in the above parameters and postoperative complications (P>0.05). The postoperative hospital stay were 3 (2-18) days in the robotic group and 4 (2-14) in the thoracoscopic group (P=0.014). The hospitalization cost was 67 489(26 486-89 570) yuan in the robotic group and 27 917 (16 817-67 603) yuan in the thoracoscopic group (P=0.000).ConclusionCompared with the video-assisted thoracoscopic surgery, Da Vinci robot-assisted surgery owns the same efficacy and safety in the treatment of mediastinal tumor, with shorter postoperative hospital stay, but higher cost.
ObjectiveTo summarize the clinical effect of Da Vinci robot radical gastrectomy for gastric cancer.MethodsA retrospective analysis was performed on 200 patients undergoing radical surgery for Da Vinci robotic gastric cancer from the General Surgery of the 940th Hospital of the Chinese People's Liberation Army from December 2016 to January 2018.ResultsThere were 200 cases of robotic radical gastric cancer, 99 cases of radical distal gastrectomy, and 101 cases of radical total gastrectomy. The operative time was (241.0±33.3) min, intraoperative blood loss was (146.2±110.4) mL, and the number of lymph nodes cleaned was (42±14).

Tumor diameter was (4.5±2.0) cm. The degree of tumor differentiation was high differentiation in 7 cases, moderate differentiation in 61 cases and poor differentiation in 132 cases. TNM stage was 1 case in stage Ⅰ, 62 cases in stage Ⅱ and 137 cases in stage Ⅲ. Iauren was divided into intestinal type (78 cases), diffuse type (65 cases) and mixed type (57 cases). The tumor infiltrated into submucosa in 1 case, intrinsic muscularis in 3 cases, subserosal layer in 31 cases and serosal layer in 165 cases. The tumors were located in the upper part of the stomach in 45 cases, the lower part of the stomach in 106 cases, the body of the stomach in 46 cases, the whole stomach in 1 case, and the gastroesophageal junction in 2 cases. Postoperative complications occurred in 8 cases (4%), including anastomotic leakage in 4 cases, duodenal stump fistula in 1 case, tracheoesophageal fistula in 1 case, pulmonary infection in 1 case, and gastroparesis in 1 case.ConclusionThe DaVinci robotic surgical system has less surgical injuries, quicker postoperative recovery, and better clinical efficacy.
ObjectiveTo compare short- and medium-term effects of Leonardo da Vinci robot-assisted and traditional mitral valvuloplasty.MethodsWe conducted a retrospective analysis of 74 patients who underwent mitral valvuloplasty in our hospital from January 2015 to March 2017. The patients were divided into two groups according to the mode of operation: a da Vinci group (n=29, 13 males, 16 females at an average age of 52 years) and a routine group (n=45, 18 males, 27 females at an average age of 53 years). The perioperative data of patients in the two groups were compared and analyzed.ResultsThere was no significant difference in sex, age, weight, height, body mass index (BMI), cardiac function (NYHA), hypertension, diabetes, postoperative blood transfusion and postoperative complications between the two groups (P>0.05). The tracheal intubation time, ICU retention time, hospital stay time, blood loss and postoperative drainage in the da Vinci group were shorter or less than those in the routine group (P<0.05). The operation time, cardiopulmonary bypass time and aortic clamping time in the da Vinci group were longer than those in the routine group (P<0.05). Different surgical procedures had no significant effect on left atrial diameter (LAD), left ventricular end-diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF) and mitral regurgitation (MR) 3 years after operation. There was no interaction between the mode of operation and the time of follow-up. There was no significant difference in echocardiographic evaluation in the same period (P>0.05).ConclusionDa Vinci operation shortens the rehabilitation process of patients compared with traditional surgery. For short- and medium-term follow-up results, there is no difference between Leonardo da Vinci and traditional mitral valve surgeries, and the clinical effect of da Vinci robot-assisted mitral valvuloplasty is satisfactory, which is worthy of further clinical promotion.
