Objective To investigate the efficacy of preoperative nebulized indocyanine green (ICG)-assisted thoracoscopic anatomical lesion resection (TALR) in treating pediatric congenital pulmonary airway malformation (CPAM). Methods A retrospective analysis was conducted on clinical data of 45 children with CPAM who underwent thoracoscopic surgery at the Third Affiliated Hospital of Zhengzhou University between June 2023 and March 2025. The patients were divided into an ICG group (preoperative nebulized ICG 0.5 mg/kg+TALR) and a non-ICG group (TALR under white light), with perioperative and postoperative recovery parameters compared between groups. Results A total of 45 children [22 males, 23 females; median age 7.4 (1.1-75.0) months] were enrolled. The ICG group (n=22) and non-ICG group (n=23) both achieved uneventful recoveries. Compared to the non-ICG group, the ICG group demonstrated significantly shorter surgical duration [91.3 (38.0-144.0) min vs. 100.0 (50.0-175.0) min, P=0.032], reduced intraoperative blood loss [3.0 (2.0-10.0) mL vs. 5.0 (1.0-10.0) mL, P=0.049], shorter postoperative drainage duration [2.7 (1.9-3.9) d vs. 3.4 (1.8-19.9) d, P=0.003], and shortened hospital stay [4.6 (2.9-9.8) d vs. 5.0 (3.9-21.5) d, P=0.013]. Residual lesions occurred in 2 patients from the non-ICG group but none in the ICG group. Intragroup comparisons revealed significant improvements in ratio of time to peak tidal expiratory flow to expiratory time, ratio of volume to peak tidal expiratory flow to expiratory volume, and tidal volume per kilogram after surgery in both groups (P<0.05), though intergroup differences showed no statistical significance (P>0.05). Conclusion Preoperative nebulized ICG administration facilitates lesion identification in CPAM, reduces technical difficulty of TALR, enhances therapeutic outcomes, and provides valuable assistance for performing TALR procedures.

OBJECTIVE:The clinical efficacy and safety of preoperative intravenous glucocorticoids in patients undergoing lower limb joint arthroplasty remain controversial.Therefore,we conducted a meta-analysis based on randomized controlled trials to evaluate the efficacy and safety of preoperative intravenous glucocorticoids for clinical treatment using lower limb joint arthroplasty. METHODS:We systematically searched randomized controlled trials on the effects of preoperative intravenous glucocorticoids on the efficacy and safety of lower limb joint arthroplasty in Chinese and foreign databases up to June 2023,including PubMed,Embase,Web of Science,Cochrane Library,WanFang Data,and CNKI.The trial group was injected with intravenous glucocorticoid before operation to control pain.The control group received placebo or intravenous saline.Outcome measures included postoperative resting pain score,postoperative C-reactive protein,postoperative 5-m walking test pain score,length of hospital stay,operation time,postoperative morphine opioid supplemental dose,postoperative nausea and vomiting reaction,and postoperative periprosthesis infection complications. RESULTS:(1)A total of nine randomized controlled trials included 613 patients(n=311 in the glucocorticoid group,n=302 in the control group).(2)Compared with the control group,preoperative intravenous administration of glucocorticoids significantly reduced the resting pain scores of patients at 6 and 12 hours after surgery,as well as the pain scores of patients walking for 5 m on the first day after surgery.In addition,the need for additional morphine opioids and postoperative nausea and vomiting were reduced in the glucocorticoid group.The inflammatory C-reactive protein was lower than that of the control group within three days after surgery,and the length of hospital stay was shortened after intravenous glucocorticoid injection(P<0.05).(3)However,there were no significant differences in the incidence of infection after arthroplasty,operation time,and pain scores at 24 and 48 hours between the two groups. CONCLUSION:As an effective perioperative multi-modal analgesia protocol,intravenous injection of glucocorticoids before surgery is an effective and safe method to reduce hyperacute pain and improve joint mobility in patients with lower limb joint arthroplasty.More research is needed to determine the optimal dose and type of glucocorticoids for maximum pain control.

Objective:To compare the efficacy of gasless robotic surgery via transaxillary approach and combined axillary-retroauricular approach for unilateral N1b PTC, and to explore the safety and effectiveness of gasless robotic surgery via transaxillary approach for unilateral N1b PTC. Methods:Unilateral N1b PTC patients who underwent surgery in the Department of Otolaryngology, Sun Yat Sen Memorial Hospital, Sun Yat sen University between July 2016 and December 2024 were included and analyzed. According to the inclusion and exclusion criteria and the differences of surgical approaches, the patients were divided into the transaxillary approach（TA） group and the combined axillary-retroauricular approach（TARA） group. The demographic data, operation time, intraoperative blood loss, postoperative drainage volume, postoperative complications, shoulder function evaluation, postoperative visual analogue scale（VAS） of neck aesthetics and recurrence of the two groups were statistically analyzed. Results:A total of 88 patients undergoing gasless robotic surgery were included in this study, including 23 cases in the TA group and 65 cases in the TARA group. The proportion of males in the TA group was significantly higher than that in the TARA group（56.5% vs 21.5%, χ²=9.776, P=0.002）. The total operation time in the TA group was significantly lower than that in the TARA Group（180.00[155.00, 220.00]min vs 220.00[177.50, 272.50]min, z=-2.775, P=0.006）, and the postoperative blood loss in the TA group was significantly lower than that in the TARA Group（30.00[20.00, 50.00]ml vs 50.00[30.00, 60.00]ml, Z=-2.127, P=0.033）. The proportion of area Ⅱ-Ⅴ in the TA group and the TARA group was 87.0% and 70.8%, respectively, and there was no significant difference between the two groups（P>0.05）. There was no significant difference in lateral cervical lymph node dissection and central lymph node dissection between the two groups（P>0.05）. During the follow-up period, no recurrence was found in the two groups, and there was no significant difference in the incidence of complications between the two groups（P>0.05）. According to the stratification of dynamic recurrence risk assessment, it can be seen that the proportion of curative effect satisfaction in the TA group was as high as 95.7%, and that in the TARA group was as high as 81.5%, with no significant difference between the two groups. There was no significant difference in VAS score of neck, Constant Shoulder Score and NDⅡ scale between the two groups（P>0.05）. Conclusion:Gasless robotic surgery via transaxillary approach for unilateral N1b PTC is safe and feasible, and the amount postoperative lymph node acquisition is equivalent to that of combined axillary-retroauricular approach, which can provide a new choice for the treatment of unilateral N1b PTC patients.

Objective:To evaluate the safety, feasibility, and technical advantages of the domestic Jingfeng single-port robotic surgical system in transoral and transaxillary approach surgeries for multisite diseases. Methods:A retrospective analysis was conducted on the clinical data of 6 patients who underwent Jingfeng SP1000 single-port robotic-assisted surgery at our hospital from June 2025 to July 2025. They were divided into the transoral robotic surgery group（4cases） and the transaxillary approach thyroid cancer radical resection group（2cases） based on surgical approaches. The transoral robotic surgery group included extended resection of right tonsillar cancer with cervical lymph node dissection, epiglottic cyst resection, extended resection of right pyriform sinus cancer with cervical lymph node dissection, and surgery for epiglottic cyst and obstructive sleep apnea（OSA）. For each case, parameters including operative time, intraoperative blood loss, perioperative complications, robotic operation performance, and postoperative recovery were recorded. Results:All 6 surgeries were successfully completed without conversion to open surgery or system failure. In the transoral robotic surgery group, the mean robotic operation time was（60.00±34.88） minutes, and the mean intraoperative blood loss was 20.00（5.75，20.00）mL. In the transaxillary robotic surgery group, the robotic operation time was respectively 60.00 and 40.00 minutes, and the intraoperative blood loss was 10.00 and 5.00 mL, respectively. One case of minor perioperative complication（in the flap dissection area） occurred, with no severe complications reported. All patients recovered smoothly after surgery, with a median follow-up of 1.9 months showing no residual lesions, recurrence, or functional impairment. Conclusion:This case series confirms the safety and feasibility of the domestic Jingfeng single-port robot in transoral and axillary approach surgeries in oropharyngeal-head and neck surgery. Its single-port design reduces trauma and the risk of robotic arm collision, adapts to minimally invasive needs, and its domestic production attribute lowers costs to facilitate popularization, providing a new option for such patients.

Objective:To investigate the therapeutic effectiveness of ultrasound-guided percutaneous catheterization for continuous negative pressure drainage combined with polidocanol in treating large thyroid cysts.Method:Clinical data of 38 patients with large thyroid cysts who were treated consecutively with catheter drainage combined with polidocanol sclerotherapy by the same doctor at Beijing Tsinghua Changgung Hospital from Jan 2021 to May 2024 were retrospectively analyzed. The effectiveness and safety were statistically evaluated, and the relationship between drainage volume and cyst volume was analyzed.Results:Among the 38 patients with thyroid cysts who completed the treatment, the median follow-up was 9 months (range: 3-24 months). The effectiveness rate was 92% (35/38), of which 32 cases (84%) met the cure standard. The maximum diameter of the cysts before treatment was (4.8±1.0) cm, and the maximum diameter of the residual nodules after treatment was (1.5±1.1) cm, the difference was statistically significant ( t=17.389, P<0.01). The amount of drainage exudate is related to the volume of the cyst and the maximum diameter before treatment ( t=-3.149, P=0.003; t=-3.057, P<0.005). 19% of patients showed transient low fever after the injection of polidocanol, with no other complications. Conclusion:For large thyroid cysts, ultrasound-guided percutaneous catheterization for continuous negative pressure drainage combined with polidocanol sclerotherapy is a safe and effective method.

Objective:To compare the clinical efficacies of gasless transoral vestibular robotic surgery and open surgery for the treatment of thyroglossal duct cysts.Methods:A retrospective analysis was conducted on patients with thyroglossal duct cysts who underwent surgical treatment in the Department of Otolaryngology at Sun Yat-sen Memorial Hospital, Sun Yat-sen University from August 2020 to October 2023. According to the differences in surgical methods, patients were divided into a robotic surgery group and an open surgery group. Statistical analysis was conducted on demographic data, surgical time, bleeding volumes, drainage volumes, postoperative complications, scar conditions, postoperative aesthetic scores, and recurrence rates of the two groups of patients. For normally distributed measurement data, inter-group comparison was done via independent-sample t-test. For non-normally distributed data, Mann-Whitney U test was applied. Comparisons of composition ratios or rates were performed using the χ2 test or Fisher′s exact probability method. Results:A total of 44 patients with thyroglossal duct cysts who met the inclusion and exclusion criteria were included, including 22 males and 22 females, aged from 3 to 73 years old. Both the robotic surgery group and the open surgery group had respectively 22 cases. The maximum diameter of tumors of the open surgery group was 3.45(2.50, 4.00) cm, while the robotic surgery group measured 2.50 (2.10, 3.20) cm, with the open group demonstrating significantly larger tumor dimensions compared to the robotic group ( Z=-2.329, P<0.05). Compared to the open surgery group, the robotic surgery group showed significantly more surgical time [105.00 (95.00, 135.00) min vs. 65.00(58.75, 76.25) min, Z=-5.377, P<0.05], postoperative hospitalization time [4.00 (3.75, 5.00) days vs. 3.00(2.00, 4.00) days, Z=-3.202, P<0.05] and bleeding volume [20.00 (10.00, 20.00) ml vs. 5.00 (5.00, 10.00) ml, Z=-4.769, P<0.05], but had less scar length [0 cm vs. 4.00 (2.00, 5.00) cm, Z=-6.097, P<0.05] and better postoperative cosmetic satisfaction [10.00 (10.00, 10.00) vs. 8.00 (6.75, 8.00), Z=-5.221, P<0.05]. With follow-up of 10.0-48.0 months, both the robotic surgery group and the open surgery group showed no recurrence. There was no significant difference in the follow-up time between the two groups ( Z=-0.224, P=0.823). Conclusion:Gasless transoral vestibular robotic surgery is safe and feasible for the treatment of thyroglossal duct cysts, with efficacy comparable to traditional surgery, which can provide a new option for the treatment of thyroglossal duct cysts.

Objective:To evaluate the efficacy of neoadjuvant chemoimmunotherapy (NACI) combined with transoral robotic surgery (TORS) in the treatment of locally advanced oropharyngeal squamous cell carcinoma (OPSCC).Methods:This was a retrospective study of 15 patients with locally advanced OPSCC who underwent TORS after neoadjuvant therapy (NAT) at the Department of Otolaryngology-Head and Neck Surgery of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from April 2019 to February 2023. There were 12 males and 3 females, aged 31 to 74 years. Twelve cases were tonsil cancer, and 3 cases were tongue base cancer. There were 11 cases in stage Ⅲ and 4 cases in stage Ⅳ. Two patients received neoadjuvant chemotherapy and 13 patients received NACI, with 2 to 3 cycles, and all patients underwent TORS after multidisciplinary team consultation. The clinicopathological characteristics, surgical outcomes, and oncological results were summarized.Results:All surgeries were successfully completed with negative surgical margins, and no case was required conversion surgery. All patients were fed via nasogastric tubes postoperatively, with a median gastric tube stay of 7 days (range: 2-60 days). No tracheotomy was applied. There were no major complications such as postoperative bleeding. Pathological complete response (pCR) was found in 10 cases (76.9%) among the 13 patients with NACI. The follow-up time was 21 months (range: 10-47 months), and there was no death or distant metastasis. One patient with rT0N3M0 tonsil cancer had local recurrence 5 months after surgery. The 2-year overall survival and 2-year disease-free survival were respectively 100.0% and 93.3% in the 15 patients.Conclusion:NACI combined with TORS provides a safe, effective and minimally invasive treatment for patients with locally advanced oropharyngeal squamous cell carcinoma.
