ObjectiveTo investigate the voice function before and after surgery in patients undergoing axillary thyroidectomy with da Vinci robotic Xi system. MethodsSeventy female patients who underwent robotic thyroid cancer radical resection in Panzhihua Central Hospital from March 2022 to March 2023 were selected. The voice dysfunction index scale VHI-10, auditory perception evaluation scale GRBAS and voice analysis software were used to evaluate the voice function of patients subjectively and objectively at 1 day before operation, 1 week and 3 months after surgery. ResultsThe operative time was (128.13±48.36) min, the amount of blood loss was (16.36±8.23) mL. There were no significant differences in the points of function, physiology and emotion evaluated by VHI-10 scale at 1 week and 3 months after operation compared with those before operation (P>0.05). There were no significant differences in the three characteristics points of voice roughness, breathiness, and strain evaluated by GRBAS scale at 1 week and 3 months after operation (P>0.05). At 1 week after operation, the total hoarseness grade and asthenia evaluated by GRBAS scale were increased in different degrees as compared with those before operation and the difference was statistically significant (P<0.05), while the total hoarseness grade and asthenia points were decreased at 3 months after operation and there was no significant difference as compared with that before operation (P>0.05). Voice acoustic analysis results showed that there were no significant differences in fundamental frequency, jitter, shimmer and harmonic to noise ratio of the patients between at 1 week or 3 months after operation and before operation (P>0.05). The maximum phonation time (MPT) of patients was decreased at 1 week after operation as compared with that before operation, and the difference was statistically significant (P<0.05). The MPT of the patients recovered at 3 months after operation, and there was no significant difference as compared with that before operation (P>0.05). The dysphonia severity index (DSI) of patients at 1 week after surgery was decreased as compared with that before surgery, and the difference was statistically significant (P<0.05). The DSI was increased at 3 months after operation and there was no significant difference as compared with that before operation (P>0.05). ConclusionRobot radical thyroidectomy via axillary breast is safe and can protect the voice function.
Objective To investigate the feasibility and effectiveness of robot-assisted posterior minimally invasive access in treatment of thoracolumbar tuberculosis via transforaminal expansion approach. Methods A clinical data of 40 patients with thoracolumbar tuberculosis admitted between January 2017 and May 2022 and met the selection criteria was retrospectively analyzed. Among them, 15 cases were treated with robot-assisted and minimally invasive access via transforaminal expansion approach for lesion removal, bone graft, and internal fixation (robotic group), and 25 cases were treated with traditional transforaminal posterior approach for lesion removal and intervertebral bone grafting (traditional group). There was no significant difference in the baseline data between the two groups (P>0.05) in terms of gender, age, lesion segment, and preoperative American Spinal Injury Association (ASIA) grading, Cobb angle, visual analogue scale (VAS) score, erythrocyte sedimentation rate (ESR), and C reactive protein (CRP). The outcome indicators were recorded and compared between the two groups, including operation time, intraoperative bleeding volume, hospital stay, postoperative bedtime, complications, ESR and CRP before operation and at 1 week after operation, the level of serum albumin at 3 days after operation, VAS score and ASIA grading of neurological function before operation and at 6 months after operation, the implant fusion, fusion time, Cobb angle of the lesion, and the loss of Cobb angle observed by X-ray films and CT. The differences of ESR, CRP, and VAS score (change values) between pre- and post-operation were calculated and compared. Results Compared with the traditional group, the operation time and intraoperative bleeding volume in the robotic group were significantly lower and the serum albumin level at 3 days after operation was significantly higher (P<0.05); the postoperative bedtime and the length of hospital stay were also shorter, but the difference was not significant (P>0.05). There were 2 cases of poor incision healing in the traditional group, but no complication occurred in the robotic group, and the difference in the incidence of complication between the two groups was not significant (P>0.05). There were significant differences in the change values of ESR and CRP between the two groups (P<0.05). All Patients were followed up, and the follow-up time was 12-18 months (mean, 13.0 months) in the traditional group and 12-16 months (mean, 13.0 months) in the robotic group. Imaging review showed that all bone grafts fused, and the difference in fusion time between the two groups was not significant (P>0.05). The difference in Cobb angle between the pre- and post-operation in the two groups was significant (P<0.05); and the Cobb angle loss was significant more in the traditional group than in the robotic group (P<0.05). The VAS scores of the two groups significantly decreased at 6 months after operation when compared with those before operation (P<0.05); the difference in the change values of VAS scores between the two groups was not significant (P>0.05). There was no occurrence or aggravation of spinal cord neurological impairment in the two groups after operation. There was a significant difference in ASIA grading between the two groups at 6 months after operation compared to that before operation (P<0.05), while there was no significant difference between the two groups (P>0.05). Conclusion Compared with traditional posterior open operation, the use of robot-assisted minimally invasive access via transforaminal approach for lesion removal and bone grafting internal fixation in the treatment of thoracolumbar tuberculosis can reduce the operation time and intraoperative bleeding, minimizes surgical trauma, and obtain definite effectiveness.
ObjectiveTo compare and analyze the therapeutic effect of robotic and laparoscopic radical resection of rectal cancer for obese patients with rectal adenocarcinoma. MethodsThe retrospective cohort study was conducted. The clinicopathologic data of 217 obese patients with rectal adenocarcinoma who were treated in the First Affiliated Hospital of Zhengzhou University from October 2017 to January 2020 were collected, 104 patients received radical resection of rectal cancer assisted by Da Vinci robotic surgical system and were assigned to the robot group, 113 patients underwent laparoscopic-assisted radical resection of rectal cancer and were assigned to the laparoscope group. The perioperative indexes, pathological examination, and postoperative recovery of urogenital function were compared. ResultsThere were no significant differences between the two groups in the gender, age, body mass index, distance from lower edge of tumor to anal edge, tumor diameter, American Association of Anesthesiologists classification, preoperative complications, preoperative carcinoembryonic antigen level, tumor differentiation, and TNM stage (P>0.05). The operations were successfully completed in all patients and there was no conversion to laparotomy and perioperative death. There were no significant differences between the two groups in the operation time, first exhaust time, first eating liquid food time, first getting out of bed activity time, drainage tube placement time, prophylactic stoma rate, and postoperative complications (P>0.05). The intraoperative blood loss and total hospital stay in the robot group were less than those of the laparoscope group (P<0.05). The International Prostate Symptom Score of the robot group was lower than that of the laparoscope group at 3, 6, and 12 months after operation (P<0.05). The International Index of Erectile Function-15 score of male patients and Female Sexual Function Index-19 score of female patients in the robot group were higher than those in the laparoscope group at 3, 6, and 12 months after operation (P<0.05). ConclusionsRobotic surgery is safe and effective in treatment of obese patients with rectal adenocarcinoma. Compared with laparoscopic surgery, robotic surgery could benefit patients more in protecting postoperative genitourinary function.

Objective To compare three surgical treatments for mediastinal mass with myasthenia gravis. Methods Retrospective analysis was performed on the clinical data of 53 patients who underwent extended thymectomy between January 2010 and December 2017 in our hospital. There were 29 males and 24 females, aged 17-73 years. Patients were divided into three groups according to the surgical methods: a group A (video-assisted thoracoscopic surgery with the da Vinci robotic system, n=22), a group B (video-assisted thoracoscopic surgery, n=12) and a group C (median sternotomy, n=19). The gender distribution, age, intraoperative blood loss, operation time, postoperative extubation time, postoperative hospital stay, Osserman classification of myasthenia gravis, postoperative myasthenic remission rate, etc were compared in three groups. Results No perioperative death was observed in 53 patients. One patient in the group C suffered from postoperative myasthenic crisis and improved after active treatment. One patient with video-assisted thoracoscopic surgery was converted to median sternotomy due to the intraoperative injury of the left brachiocephalic vein. Compared with the group B and group C, the group A had shorter operation time, less intraoperative blood loss and drainage on the first postoperative day and fewer days of extubation. Postoperative hospital stay was less in the group A than that in the group C (P<0.05). The postoperative myasthenic remission rate was higher in the group A than that in the other two groups, but there was no statistical difference. Conclusion Because of the robot’s unique minimally invasive advantage, in this study, the outcome of patients with myasthenia gravis treated with Da Vinci robots and thymectomy is better than that of the remaining two groups in terms of perioperative outcomes and myasthenic remission rate. But long-term results and a large of number matching experiments are needed to confirm. However, it is undeniable that robotic surgery must be the future of the minimally invasive surgery.
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 compare the short-term outcomes of surgical repair for atrial septal defect (ASD) with a robotic (da Vinci Si) approach versus a conventional open procedure.MethodsClinical data of 140 patients undergoing ASD closure in the First Affiliated Hospital of Anhui Medical University from January 2016 to May 2020 were retrospectively analyzed. The patients were divided into a robotic group and a sternotomy group according to different surgical methods. In the robotic group, there were 67 patients including 20 males and 47 females at a median age of 40.0 (25.0) years, and in the sternotomy group there were 73 patients including 23 males and 50 females at a median age of 41.0 (29.0) years. Multivariate linear regressions were used to produce risk-adjusted analysis of pertinent clinical characteristics. Kaplan-Meier analysis was performed to compare the speed of sternotomy versus robotic group returning to exercise or daily life.ResultsRobotic-assisted surgery was associated with significantly shorter 24 h postoperative drainage volume [220.0 (210.0) mL vs. 345.0 (265.0) mL, P<0.001], mechanical ventilation [6.0 (11.0) h vs. 8.0 (11.0) h, P=0.024], intensive care unit length of stay (LOS) [19.0 (19.0) h vs. 22.0 (25.0) h, P=0.005], postoperative hospital LOS [9.0 (5.0) d vs. 10.0(6.0) d, P=0.003], and a lower rate of perioperative blood transfusion (28.36% vs. 84.93%, P<0.001). After controlling for patient comorbidity in the multiple regression model, there remained a trend toward decreased 24 h postoperative drainage volume (β=–115.30, 95%CI–170.78 to –59.82, P<0.001), mechanical ventilation (β=–4.96, 95%CI –8.33 to –1.59, P=0.004) and postoperative hospital LOS (β=–2.31, 95%CI –3.98 to –0.63, P=0.007) in the robotic group. Kaplan-Meier analysis revealed that patients returned to exercise or daily life earlier in the robotic group [35.0 (32.0) d vs. 90.0 (75.0) d, P<0.001].ConclusionClosure of ASD can be performed safely and effectively via robotic approach. And the minimally invasive technique is beneficial to postoperative recovery.
ObjectiveTo compare the effectiveness of robot-assisted minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and open freehand TLIF for the treatment of single-level degenerative lumbar spondylolisthesis (DSL) and analyse the influence on postoperative adjacent segmental degeneration (ASD). Methods The clinical data of 116 patients with L4、5 DLS who were admitted between November 2019 and October 2021 and met the selection criteria were retrospectively analyzed. According to the surgical methods, they were divided into the robotic group (45 cases, who underwent robot-assisted MIS-TLIF) and the open group (71 cases, who underwent open freehand TLIF). There was no significant difference in baseline data such as gender, age, body mass index, DLS Meyerding grading, and preoperative Pfirrmann grading, Weishaupt grading, L3, 4 intervertebral disc height (DH), L3, 4 intervertebral mobility, sagittal parameters [including pelvic incidence (PI), lumbar lordosis (LL), sacral slope (SS), pelvic tilt (PT)], and Cage height (P>0.05). The grade of facet joint violation (FJV) by pedicle screws on the superior articular process was assessed postoperatively. Sagittal parameters, L3, 4 DH, L3, 4 DH loss, and L3, 4 intervertebral mobility were measured preoperatively and at last follow-up in order to determine whether ASD occurred. Based on the occurrence of postoperative ASD, logistic regression analysis was used to identify the risk factors for ASD after TLIF. Results Patients in both groups were followed up 21-47 months, with a mean of 36.1 months; there was no significant difference in the follow-up time between the two groups (P>0.05). The occurrence of postoperative FJV was significantly better in the robotic group than in the open group (P<0.05). At last follow-up, the difference in the change values of sagittal parameters PI, PT, SS, and LL was not significant when comparing the two groups of patients (P>0.05); the change values of L3, 4 DH and L3, 4 DH loss in the robotic group were smaller than those in the open group, and the change value of L3, 4 intervertebral mobility was larger than that in the open group, and the differences were significant (P<0.05). At last follow-up, ASD occurred in 8 patients (17.8%) in the robotic group and 35 patients (49.3%) in the open group, and the difference in ASD incidence between the two groups was significant (P<0.05). logistic regression analysis showed that open surgery, preoperative Pfirrmann grading Ⅳ-Ⅴ, preoperative Weishaupt grading ≥2, and postoperative FJV grading ≥1 were risk factors for the development of ASD after TLIF (P<0.05). ConclusionCompared with traditional open surgery, orthopedic robot-assisted MIS-TLIF in the treatment of single-level DLS can more accurately insert pedicle screws, reduce the loss of DH and the occurrence of FJV, and effectively reduce the incidence of mid-postoperative ASD. Preoperative disc and synovial joint degeneration in adjacent segments, nonrobotic-assisted minimally invasive therapy, and FJV are risk factors for ASD after TLIF.
Objective To investigate the clinical application of da Vinci surgical system in nipple sparing mastectomy (NSM) and immediate one-stage implant-based breast reconstruction. Methods Five cases of breast cancer who underwent NSM and immediate implant-based breast reconstruction were analyzed from March 2022 to April 2022. Evaluation endpoints included the key points of operation, duration of surgery, postoperative complications, and patient-reported outcomes. Results Two patients underwent implant-based postpectoral breast reconstruction without mesh. Three patients received prepectoral reconstruction with biological mesh, 2 of which underwent bilateral breast reconstruction. Operating duration of 5 patients was 240–320 min, with an average of 291 min. The blood loss was 10–30 mL, with an average of 18 mL. No patient switched to open surgery due to the uncontrolled bleeding. The average drainage volume was 78 mL/d (60–100 mL/d) in the first 3 days and 38 mL/d (30–50 mL/d) in the 3 to 7 days after operation. The drainage tube was removed 10–18 days after operation, with an average of 13.2 days. No postoperative infections or nipple-areolar complex necrosis were observed. The inpatient stay was 1–3 days, with an average of 1.8 days. One month after operation, the BREAST-Q satisfaction score was 64–82, with an average of 76.20. The average cost for operation was 45 072 RMB (43 420–47 524 RMB). Conclusions The robotic NSM and immediate one-stage implant-based breast reconstruction is a safe procedure with better clinical outcomes and favorable patients’ satisfaction. However, the robotic system has longer operation time and higher cost. It still needs to be personalized in the clinical practice.
