ObjectiveTo explore the method of preventing heat steam induced skin damage in robotic nipple-sparing mastectomy and immediate breast reconstruction (R-NSM-IBR) using Da Vinci Robots. Methods A clinical data of 128 female patients with breast cancer, who were treated with R-NSM-IBR between September 2022 and December 2023 and met the selection criteria, was retrospectively analyzed. During robotic nipple-sparing mastectomy, the breasts were covered with gauze cooled by ice water to reduce skin temperature in 99 cases (group A) and were not treated in 29 cases (group B). There was no significant difference in the age, affected side, body mass index, pathological type of breast cancer, and constituent ratios of adjuvant chemotherapy and neoadjuvant chemotherapy between the two groups (P>0.05). Intraoperative breast skin temperature, unilateral robotic nipple-sparing mastectomy time, and the incidence of complications of breast heat steam induced skin damage were recorded. Results The time for unilateral robotic nipple-sparing mastectomy was (77.18±9.23) minutes in group A and (76.38±12.88) minutes in group B, with significant difference between the two groups (P<0.05). The intraoperative breast skin temperature was significantly lower in group A than in group B [(25.61±0.91)℃ vs (33.38±1.14)℃; P<0.05]. Seven cases of heat steam skin damage occurred during operation, including 2 cases (2.0%) in group A and 5 cases (17.2%) in group B, with a significant difference in incidence between the two groups (P<0.05). Among them, 1 patient in group B had a vesication rupture and infection, which eventually led to the removal of the implant; the rest of the patients were treated with postoperative interventions for skin recovery. Conclusion The use of breast covered with gauze cooled by ice water during R-NSM-IBR can effectively reduce the risk of heat steam induced skin damage.
Objective To investigate the risk factors for arrhythmia after robotic cardiac surgery. Methods The data of the patients who underwent robotic cardiac surgery under cardiopulmonary bypass (CPB) from July 2016 to June 2022 in Daping Hospital of Army Medical University were retrospectively analyzed. According to whether arrhythmia occurred after operation, the patients were divided into an arrhythmia group and a non-arrhythmia group. Univariate analysis and multivariate logistic analysis were used to screen the risk factors for arrhythmia after robotic cardiac surgery. ResultsA total of 146 patients were enrolled, including 55 males and 91 females, with an average age of 43.03±13.11 years. There were 23 patients in the arrhythmia group and 123 patients in the non-arrhythmia group. One (0.49%) patient died in the hospital. Univariate analysis suggested that age, body weight, body mass index (BMI), diabetes, New York Heart Association (NYHA) classification, left atrial anteroposterior diameter, left ventricular anteroposterior diameter, right ventricular anteroposterior diameter, total bilirubin, direct bilirubin, uric acid, red blood cell width, operation time, CPB time, aortic cross-clamping time, and operation type were associated with postoperative arrhythmia (P<0.05). Multivariate binary logistic regression analysis suggested that direct bilirubin (OR=1.334, 95%CI 1.003-1.774, P=0.048) and aortic cross-clamping time (OR=1.018, 95%CI 1.005-1.031, P=0.008) were independent risk factors for arrhythmia after robotic cardiac surgery. In the arrhythmia group, postoperative tracheal intubation time (P<0.001), intensive care unit stay (P<0.001) and postoperative hospital stay (P<0.001) were significantly prolonged, and postoperative high-dose blood transfusion events were significantly increased (P=0.002). Conclusion Preoperative direct bilirubin level and aortic cross-clamping time are independent risk factors for arrhythmia after robotic cardiac surgery. Postoperative tracheal intubation time, intensive care unit stay, and postoperative hospital stay are significantly prolonged in patients with postoperative arrhythmia, and postoperative high-dose blood transfusion events are significantly increased.
Surgery has played an important role in treating non-small cell lung cancer (NSCLC). Resection is usually the first choice for NSCLC patients in stage Ⅰ and stage Ⅱ, and it is also an important part of the comprehensive treatment for the stage ⅢA patients. Standard surgery of NSCLC includes resection of the primary tumor lesion and swee-ping of ipsilateral lymph nodes and mediastinal lymph nodes. The goal of treatment for lung cancer in early stage aims to decrease the rate of recurrence and mortality. In recent years, video-assisted thoracoscopic surgery and da Vinci robotic minimal invasive surgery have made gratifying achievements, especially for small peripheral lung nodules surgery. For patients with NSCLC at stage ⅢA, the central focus of research is about identifying patients who will benefit in the surgery combining with chemotherapy and radiotherapy, therefore to choose the appropriate surgery.
ObjectiveTo summarize the clinical experience of 180 general surgeries under da Vinci surgical system. MethodsFrom January 2009 to October 2010, 180 patients with hepatopancreaticobiliary and gastrointestinal disease underwent robotic surgeries by using da Vinci surgical system. The case distribution, intra-and post-operative data were analyzed. ResultsA total of 171 patients had underwent total robotic surgeries and nine patients converted to hand-assisted procedure (5.0%, 9/180). The surgery for hepatic portal was performed in 63 cases of patients, including surgery for hilar cholangiocarcinoma in 36 cases, gallbladder carcinoma in 10 cases, complex calculus of intrahepatic duct in 12 cases, and iatrogenic biliary duct injury in 5 cases. The pancreatic surgery was performed in 44 cases of patients, including pancreatoduodenectomy in 16 cases, distal pancreatectomy in 6 cases, medial pancreatectomy in 1 case, pancreatic cyst-jejunum anastomosis in 1 case, and palliative surgery in 20 cases. Hepatic surgery was in 19 cases and gastrointestinal surgery in 12 cases of patients. Other procedures were in 42 cases of patients, including common bile duct exploration and removing the stone, retroperitoneal lymph nodes dissection, and splenectomy, etc. All of ten cases of patients with obstructive suppurative cholangitis received emergency surgery by the robot and postoperative infection symptoms were controlled, and shock was corrected quickly. No death occurred during the perioperative period. Postoperative complications occurred in 12 cases (6.7%, 12/180) and 2 cases died (1.1%, 2/180). Conclusionsda Vinci surgical system can carry out all kinds of general surgery, especially complicated and difficult hepatobiliary and pancreatic surgery, which improves the development of minimally invasive surgery.
Objective To evaluate the effects of robot-assisted Ivor Lewis esophagectomy (RAILE) in surgical treatment of esophageal cancer. Methods We retrospectively analyzed the clinical data of 70 patients diagnosed with mid-lower esophageal cancer undergoing RAILE in the Department of Thoracic Surgery in Ruijin Hospital Affiliated to Shanghai Jiaotong University between May 2015 and April 2018. There were 54 males and 16 females at average age of 62.0±7.6 years. Forty patients underwent circular end-to-end stapled intrathoracic anastomosis and 30 had a double-layered, completely hand-sewn intrathoracic anastomosis. Results The mean operating time was 308.7±60.6 minutes. And blood loss was 190.0±95.1 ml. There were 2 patients who underwent conversion to thoracotomy. There was no in-hospital and 30-day mortality. Overall complications were observed in 24 patients (34.3%), of whom 6 patients (8.6%) had anastomotic leakage. The median length of hospitalization was 9.0 (interquartile range, IQR, 5.0) days. The mean tumor size was 3.2±1.5 cm, and R0 resection was achieved in all patients. The mean number of totally dissected lymph nodes was 19.3±8.7. Conclusion RAILE is safe and technically feasible with satisfactory perioperative outcomes.
ObjectiveTo evaluate the efficacy of robotic intersphincteric resection (ISR) for rectal cancer.MethodsA literature search was performed using the China biomedical literature database, Chinese CNKI, Wanfang, PubMed, Embase, and the Cochrane library. The retrieval time was from the establishment of databases to April 1, 2019. Related interest indicators were brought into meta-analysis by Review Manager 5.2 software.ResultsA total of 510 patients were included in 5 studies, including 273 patients in the robot group and 237 patients in the laparoscopic group. As compared to the laparoscopic group, the robot group had significantly longer operative time [MD=43.27, 95%CI (16.48, 70.07), P=0.002], less blood loss [MD=–19.98.27, 95%CI (–33.14, –6.81), P=0.003], lower conversion rate [MD=0.20, 95%CI (0.04, –0.95), P=0.04], less lymph node harvest [MD=–1.71, 95%CI (–3.21, –0.21), P=0.03] and shorter hospital stay [MD=–1.61, 95%CI (–2.26, –0.97), P<0.000 01]. However, there were no statistically significant differences in the first flatus [MD=–0.01, 95%CI (–0.48, 0.46), P=0.96], time to diet [MD=–0.20, 95%CI (–0.67, 0.27), P=0.41], incidence of complications [OR=0.76, 95%CI (0.50, 1.14), P=0.18], distal resection margin [MD=0.00, 95%CI (–0.17, 0.17), P=0.98] and positive rate of circumferential resection margin [OR=0.61, 95%CI (0.27, 1.37), P=0.23].ConclusionsRobotic and laparoscopic ISR for rectal cancer shows comparable perioperative outcomes. Compared with laparoscopic ISR, robotic ISR has the advantages of less blood loss, lower conversion rate, and longer operation times. These findings suggest that robotic ISR is a safe and effective technique for treating low rectal cancer.
ObjectiveTo evaluate the curative and economic effect of da Vinci robotic lung segmentectomy. MethodWe retrospectively analyzed clinical data of 13 patients who underwent robotic lung segmentectomy (as a robotic group) and 35 patients who underwent thoracoscopic lung segmentectomy (as a thoracoscopic group) in our hospital between September 2014 and April 2015. There were 4 males and 9 females at age of 43-73 (59.1±8.9) years in the robot group and 17 males and 18 females in the thoracoscopic group at age of 30-79 (59.1+12.0) years. Effects of the two groups were compared. ResultsPostoperative hospitalization time in the robotic group was shorter than that in the thoracoscopic group (4.4±0.8 d vs. 6.3±2.5 d, P<0.05). But the cost of hospitalization in the robotic group was higher than that in the thoracoscopic group (P<0.05). The surgery indwelling catheter time and incidence of complications in the robotic group were lower than those in the thoracoscopic group with no statistical difference (P=0.053, 0.081). ConclusionRobotic lung segmentectomy is a safe and feasible operation method. With the further accumulation of clinical experience and decrease of the cost of materials, the robot will play a more important role in the future of minimally invasive thoracic surgery.
ObjectiveTo compare the effectiveness of robot-assisted (RA) minimally invasive surgery versus traditional fluoroscopy-assisted (FA) open posterior fixation surgery in treating thoracolumbar fractures with ankylosing spondylitis (AS). MethodsA clinical data of 21 cases of thoracolumbar fractures with AS who met the selection criteria between December 2016 and December 2023 was retrospectively analyzed. Ten cases underwent RA minimally invasive surgery group (RA group) and 11 cases underwent FA open posterior fixation surgery (FA group). There was no significant difference in gender, age, fracture segment distribution, fracture type, time from injury to surgery, visual analogue scale (VAS) score, and American Spinal Injury Association (ASIA) grading between RA group and FA group (P>0.05). The operation time, intraoperative blood loss, radiation exposure time, radiation dose, hospital stay, and complications of the two groups were recorded. According to Gertzbein-Robbins criteria, the accuracy of screw implantation was evaluated by CT within 1 week after surgery. During follow-up, pain and nerve function were evaluated by VAS score and ASIA grading. ResultsAll patients underwent surgery successfully, and there was no significant difference in operation time (P>0.05). The intraoperative blood loss and hospital stay in the RA group were significantly less than those in the FA group (P<0.05), and the radiation exposure time and radiation dose were significantly more than those in the FA group (P<0.05). A total of 249 pedicle screws were implanted in the two groups, including 118 in the RA group and 131 in the FA group. According to the Gertzbein-Robbins criteria, the proportion of clinically acceptable screws (grades A and B) in the RA group was significantly higher than that in the FA group (P<0.05). Patients in both groups were followed up 3-12 months, with an average of 6.8 months. The VAS scores of the two groups after surgery were significantly lower than those before surgery, and the differences were significant (P<0.05). The RA group had lower scores than the fluoroscopy group at 1 week and 3 months after surgery (P<0.05). There was no significant difference in neurological function grading between groups at 1 week and 3 months after surgery (P>0.05). In the FA group, 1 case of deep infection and 1 case of deep vein thrombosis of lower extremity occurred, while no complication occurred in the RA group, and there was no significant difference in the incidence of complications between groups (P>0.05). Conclusion Both RA minimally invasive surgery and FA open posterior fixation surgery can achieve good effectiveness. Compared with the latter, the former has more advantages in terms of intraoperative blood loss, hospital stay, and accuracy of pedicle screw insertion.
ObjectivesTo investigate the safety and efficacy of robot-assisted surgery for mediastinal tumor. MethodsWe respectively analyzed the clinical data of 47 patients with clinical diagnosis of mediastinal tumor undergoing robot-assisted surgery in our hospital from May 2009 to March 2015. There were 29 males and 18 females at age of 48 (20-78) years. Robotic instruments were used through two 8 mm thoracoscopic ports and camera placed through a 12 mm observation port, without any additional utility incision. ResultsAll 47 surgeries were accomplished successfully. The operative time was 73±36 minutes. The blood loss was 48±15 ml. There was only one conversion due to bleeding during the operation. No perioperative mortality or morbidity occurred. There was no perioperative transfusion. Learning curve showed operative time shortened sharply as the procedures increased. After 20 cases of procedure, operative time was stabilized as the learning curve established. The equation is y(min)=-20.41ln(x)+119.43, R2=0.312, P<0.01. ConclusionRobot-assisted surgery for mediastinal tumor are initially proved safe and feasible with great perspective in the new age of minimally invasive thoracic surgery.
ObjectiveTo determine postoperative pain of the robotic technique for the patients with lobectomy. MethodsWe retrospectively analyzed the clinical data of 120 patients with lobectomy between October 2014 and May 2015 in our hospital. The patients are divided into two groups:a robotic group, including 40 patients with 16 males and 24 females at age of 59.7±7.2 years, undergoing robotic lobectomy, and a video-assisted thoraciscopic surgery (VATS) lobectomy group (a VATS group) including 80 patients with 29 males and 51 females at age of 61.2±8.9 years, undergoing VATS lobectomy. We used the numerical rating scale (NRS) and verbal rating scale (VRS) to assess the pain level on the first day, the 7th day and the 30th day after the surgery. The pain level of the two groups was compared. ResultsThe patients in the two groups both felt pain. There were no statistical differences in the scores of VRS and NRS on the first day, the 7th day and the 30th day after the surgery between the two group (P>0.05). The pain score of the patients in the two groups decreased with no statistical difference from the first day to the 30th day after the surgery (P>0.05). ConclusionThe patients with robotic lobectomy have similar pain level after surgery compared with the patients with VATS lobectomy.
