Surgical operations are one of the high-risk activities in modern society, and surgeons in this high-pressure environment require not only excellent technical skills but also well-rounded non-technical skills. Non-technical skills encompass key abilities such as situational awareness, decision-making, communication and teamwork, leadership, and stress management, as well as the capacity for error correction feedback loops, emotional intelligence, and adaptability to complex environments. These “soft skills” help surgeons to more effectively handle emergencies during surgery, optimize team collaboration, ensure patient safety, and increase the success rate of operations. Western countries have systematized non-technical skills into physicians’ training programs, while in China, further attention and promotion are still needed. By establishing comprehensive non-technical skill assessment standards and systematic training programs, the overall quality of surgeons can be enhanced, thereby ensuring patient safety, improving clinical outcomes, and fulfilling the professional mission of surgeons.

OBJECTIVE To investigate the improved anesthesia method of arytenoid cartilage reduction under general anesthesia in the treatment of arytenoid dislocation.METHODS The clinical data of 12 patients who underwent modified arytenoid cartilage reduction under general anesthesia in Beijing Tongren Hospital from July 2020 to March 2024 were retrospectively analyzed.To evaluate and analyze the modified anesthesia method of maintaining low degree of neuromuscular block during operation,the recovery of arytenoid cartilage movement and sound after operation.RESULTS All the 12 patients successfully completed arytenoid cartilage reduction.The articulation,arytenoid movement and glottis closure were improved significantly.Compared with the total voice handicap index(VHI),physical scores,functional scores and emotional scores before reduction,the scores at 1 month after surgery were significantly lower[83.5(75-91)vs.13(7-19),30.5(26.5-33)vs.5.5(3-7),25.5(22.5-29)vs.4(2-6),26(23.5-30)vs.4(1.5-6),P<0.001].No complications such as laryngeal spasm and laryngeal edema occurred during perioperative period.CONCLUSION Arytenoid cartilage reduction under modified general anesthesia has high safety,good patient cooperation and high reduction success rate.It provides a new option for the treatment of arytenoid dislocation.

Objective:To explore the factors influencing the recovery of swallowing function after a brainstem hemorrhage and to construct a prediction model.Methods:Clinical data on 134 persons with dysphagia after a brainstem hemorrhage were collected retrospectively. According to their swallowing ability at discharge, the patients were divided into a swallowing recovery group and a non-recovery group. Univariate correlation analysis and multivariate logistic regression analysis were used to explore the independent factors influencing the recovery of swallowing function and to construct a prediction nomogram. The receiver operating characteristics (ROC) curves were evaluated to analyze the nomogram′s predictive value and those of the relevant influencing factors.Results:Sixty-two of the patients (46%) had recovered their swallowing function at discharge, while 72 (54%) had not. Univariate correlation analysis showed that there had been significant differences in tracheal intubation, NIHSS score, FOIS score, Barthel index and Glasgow coma scale (GCS )score between the two groups, on average. The multivariate logistic regressions showed that a low NIHSS score, a high FOIS score and a high GCS score were independent predictors of swallowing function recovery, so they were used in the prediction model. ROC curve analysis showed that the area under the curve (AUC) of the prediction model was 0.953 (95% CI: 0.902~0.982) with a sensitivity of 87% and a specificity of 93%. The model′s predictions were thus better than using an NIHSS score, GCS score or FOIS score alone. Conclusions:NIHSS score, GCS score and FOIS score can independently predict the recovery of swallowing function after a brainstem hemorrhage. A prediction model constructed using all three has good predictive power.

Objective To explore and identify the nutritional/inflammatory indicator with the highest predictive potential for overall survival(OS)in postoperative tumor patients so as to provide guidance for postoperative rehabilitation of tumor patients.Methods Data from 3 191 surgical patients were collected,including 15 nutritional/inflammatory indicators.The maximum selection rank statistic method was used to calculate the optimal cut-off values for continuous indicators.The Kaplan-Meier method was used to assess OS,and Cox proportional hazards models were used to analyze the association between the aforementioned 15 indicators and survival.The predictive value of these 15 indicators was evaluated with receiver operating characteristic(ROC)curves and C-index.Results Multivariate analysis showed that all 15 indicators were significantly associated with poorer OS in surgical patients(P＜0.05 for all).Time-dependent area under the curve(AUC)and C-index analysis indicated that 3 indicators with the highest predictive potential in OS in postoperative tumor patients were the nutritional risk index(NRI)(C-index:0.597),C-reactive protein-to-albumin ratio(CAR)(C-index:0.587),and C-reactive protein-to-lymphocyte ratio(CLR)(C-index:0.587).The optimal cut-off value for NRI was determined to be 104.31(i.e.,NRI＜104.31 suggests malnutrition)with the maximum selection rank statistic method,the optimal cut-off value for CAR to be 0.05(i.e.,CAR≥0.05 suggests a strong inflammatory response,often accompanied by malnutrition),and the optimal cut-off value for CLR to be 1.18(i.e.,CLR≥1.18 suggests a strong inflammatory response).Subgroup analysis indicated that NRI,CAR,and CLR had good correlation with tumor staging,and there were significant differences between tumor node metastasis(TNM)Ⅲ/Ⅳ stage patients and TNM Ⅰ/Ⅱ stage patients when there was a strong inflammatory response or malnutrition.Conclusion In postoperative tumor patients,NRI,CLR,and CAR have high prognostic value.Combining these with the patient's clinical stage,it enables more precise guidance for clinical diagnosis and treatment strategies.

Objective:To explore the relationship between the morphology of the carotid siphon, its related risk factors, and cerebral blood flow perfusion in patients with arteriosclerotic cerebral small vessel disease (aCSVD), and provide imaging evidence for the etiology of aCSVD.Methods:A total of 130 aCSVD patients hospitalized in the Department of Neurology of the First People′s Hospital of Hefei from March 2022 to June 2024, all of whom underwent multimodal imaging assessments, were enrolled. The baseline data were collected, and the morphology of the carotid siphon was visually evaluated using post-processing of head and neck computed tomography angiography (CTA), which was categorized into U-type ( n=63), C-type ( n=32), and V-type ( n=35). Calcification degree was semi-quantitatively assessed based on transverse CTA images. Cerebral perfusion was measured using magnetic resonance arterial spin labeling. The relationship between different siphon segment morphologies, calcification degrees, their risk factors, and cerebral blood flow perfusion was analyzed using analysis of variance and multinomial Logistic regression. Results:Univariate analysis of the 3 siphon types showed significant differences in low-density lipoprotein cholesterol [U-type (2.44±0.84) mmol/L,V-type (2.21±0.57) mmol/L, C-type (2.89±1.07) mmol/L, F=5.578, P=0.005], calcification degree [Among the 63 cases in the U-type group, 19 cases (30.15%) had mild calcification, 20 cases (31.75%) had moderate calcification, and 24 cases (38.10%) had severe calcification; among the 35 cases in the V-type group, 20 cases (57.14%) had mild calcification, 10 cases (28.57%) had moderate calcification, and 5 cases (14.29%) had severe calcification; among the 32 cases in the C-type group, 12 cases (37.50%) had mild calcification, 14 cases (43.75%) had moderate calcification, and 6 cases (18.75%) had severe calcification; χ2=13.092, P=0.011], and total aCSVD load [modified aCSVD load score: U-type 4.00(1.00, 4.00),V-type 3.00(1.00, 4.00),C-type 2.00(2.00, 4.00), H=9.997, P=0.007]. Multivariate Logistic regression revealed that patients with U-shaped siphons had a significantly higher overall aCSVD load than those with C-shaped siphons, with a regression coefficient of 0.728, and a statistically significant difference ( OR=2.070 ,95% CI 1.026-4.178, P=0.042). Additionally, total brain and white matter cerebral blood flow were decreased in patients with U-type siphons compared to those with C-type and V-type, primarily involving bilateral superior frontal gyri, left orbital frontal gyrus, and left straight gyrus regions (false discovery rate correction, P<0.05). Conclusions:The imaging manifestations of aCSVD are closely related to the shape of the internal carotid artery siphon.The U type siphon is more likely to lead to hemodynamic changes, resulting in decreased global and regional cerebral blood flow, and demonstrating a higher overall burden of aCSVD, which has certain clinical reference value for assessing the etiology of aCSVD.

Objective:To investigate the safety and efficacy of the TRIANGLE operation after neoadjuvant chemotherapy in locally advanced pancreatic cancer(LAPC).Methods:This study is a retrospective case series analysis. Between January 2020 and December 2022, a total of 103 patients were diagnosed as LAPC who underwent neoadjuvant chemotherapy at the Pancreas Center, the First Affiliated Hospital of Nanjing Medical University. Among them, 26 patients (25.2%) underwent the TRIANGLE operation. There were 15 males and 11 females,with a age of (59±7) years (range: 49 to 74 years). The pre-treatment serum CA19-9( M(IQR)) was 248.8(391.6)U/ml (range: 0 to 1 428 U/ml),and the serum carcinoembryonic antigen was 4.1(3.8)μg/L(range: 1.4 to 13.4 μg/L). The neoadjuvant chemotherapy regimens included: mFOLFIRINOX regimen in 6 cases(23.1%), GnP regimen in 14 cases(53.8%), and mFOLFIRINOX+GnP regimen in 6 cases(23.1%). The follow-up duration extended until June 2023 or until the occurrence of the patient′s death or loss to follow-up. The Kaplan-Meier method was employed to estimate the 1-year and 3-year overall survival rates. Results:After neoadjuvant chemotherapy,CA19-9 levels decreased by 92.3(40.1)%(range:2.1% to 97.7%). Evaluation of the response to treatment revealed 13 cases(50.0%) of stable disease,11 cases(42.3%) of partial response,and 2 cases(7.7%) of complete response. The surgical operation consisted of 12 cases(46.2%) of pancreaticoduodenectomy,12 cases(46.2%) of distal pancreatectomy,and 2 cases(7.7%) of total pancreatectomy. Margin determination was based on the “standardised pathology protocol” and the “1 mm” principle. No R2 and R1(direct) resections were observed,while the R0 resection rate was 61.5%(16/26), and the R1(1 mm) resection rate was 38.5%(10/26).The R1(1 mm) resection rates for the anterior margin,posterior margin,transected margin,portal vein groove margin,and uncinate margin were 23.1%(6/26),19.2%(5/26),12.5%(3/24),2/14, and 1/12, respectively. The overall postoperative complication rate was 57.8%(15/26),with major complications including grade B/C pancreatic fistula 25.0%(6/24,excluding 2 cases of total pancreatectomy),delayed gastric emptying in 23.1%(6/26),wound complications 11.5%(3/26),postoperative hemorrhage 7.7%(2/26), chylous fistula 7.7%(2/26) and bile fistula 3.8%(1/26). No reoperation was performed during the perioperative period(<90 days). One patient died on the 32 nd day postoperatively due to a ruptured pseudoaneurysm. A total of 25 patients were followed up,with a follow-up time of 21(24)months(range: 8 to 42 months). During the follow-up period,8 cases(32.0%) died due to tumor recurrence and metastasis,while 17 patients(68.0%) remained alive,including 11 cases of disease-free survival,5 cases of distant metastasis,and 1 case of local recurrence. The overall survival rates at 1- and 3-year after the initiation of neoadjuvant chemotherapy were 95.8% and 58.9%, respectively. The overall survival rates at 1- and 3-year after surgery were 77.7% and 57.8%, respectively. Conclusion:Performing pancreatoduodenectomy according to the Heidelberg triangle protocol in LAPC patients after neoadjuvant chemotherapy might increase the R0 resection rate without increasing perioperative mortality or the incidence of major postoperative complications.
