Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

OBJECTIVE To analyze the effects of the national centralized drug procurement （NCDP） policy on drug availability and the structure of drug use in public hospitals. METHODS Using hypoglycemic， lipid-lowering， antiviral drugs， and psychiatric drugs for the treatment of mental illness and depression as objects， the interrupted time series model was used to quantitatively evaluate the changes in consumption sum of drugs， consumption amount and daily cost of the target drugs in national sample hospitals as well as the changes in per capita medication frequency， outpatient prescription amount， and medical insurance surplus of target drugs in a third grade class A hospital before and after the implementation of NCDP policy. RESULTS After the implementation of the NCDP policy， the volume for the four bid-winning drugs increased significantly （P＜0.01 for the remaining three categories except for hypoglycemic drugs）， but DDDc （P＜0.01） and the amount of related drugs （P＜0.001） decreased significantly. The volume for the non-winning drugs （except for lipid-lowering drugs） decreased significantly （P＜0.05）， and DDDc also decreased significantly （P＜0.05 for other 3 categories except for psychiatric drugs）； the volume （P＜0.01） and DDDc （P＜0.01 only for psychiatric drugs） for alternative drugs all increased except for antiviral drugs. The structure of drug use for different drugs was affected differently by the NCDP policy，and that of hypoglycemic drugs was affected obviously； the proportion of alternative drugs increased after centralized procurement. The outpatient prescription amount of each hospital significantly decreased after centralized procurement，and the decrease in the cost paid by the patients using lipid-lowering and antiviral drugs related to centralized procurement was greater than 0.60； the remaining medical insurance amount for bid-winning drugs was approximately 1.252 5 million yuan. CONCLUSIONS NCDP policy effectively alleviates the burden of medical expenditure and also drives the structure changes of drug use such as the substitution of generic drugs for original drugs， the growth of the volume of alternative drugs.

Objective:To explore the feasibility and clinical effect of repairing the wound of limbs with severe infection by the bilateral chimeric perforator flaps in the anterolateral femoral area.Methods:From December 2015 to October 2018, 12 cases of limb wounds with severe infection were repaired by the lateral femoral bilateral chimeric perforator flaps in the Department of Hand Surgery, Ruihua Affiliated Hospital of Soochow University, including five cases of traffic accident, four cases of machine strangulation and three cases of other injuries. There were eight males and four females, aged from 25 to 48 years old, with an average age of 40-year-old. All the wounds were complicated with the exposure of bone, tendon, or internal fixation and had different degrees of infection, 10 cases were of soft tissue infection, and two cases were of osteomyelitis. The wounds were outlined by sample cloth. A total of nine cases had single-wounds with the dimension of 12 cm × 11 cm to 26 cm × 11 cm, and these bilobed chimeric flaps were designed by dividing the sample cloth into two parts from the center and changing the width to the length. Three cases had two adjacent and discontinuous wounds in just one limb with an area from 6 cm × 4 cm to 14 cm × 6 cm, and the bilobed flaps were designed according to the size and the shape of these wounds. Six cases were reconstructed with the bilateral chimeric flaps of which the branches originate from one artery, three with flaps of different original arteries, two with fascia skin flaps, and one with a flap of mixed blood supply. The lateral thigh muscle or tensor fascia muscle carried in the flap was used to fill the cavity or sinus, and the donor area was sutured directly. The flap survival, wound healing, and donor area recovery were observed after the operation.Results:All the flaps survived without vascular crisis. The flap size ranged from 24 cm × 6 cm to 32 cm × 7 cm in nine cases of the single wound, and 7 cm × 5 cm to 14 cm× 7 cm in three cases with two wounds. The volume of muscle resection ranged from 4 cm × 3 cm × 2 cm to 11 cm× 6 cm × 4 cm. The average time of wound healing was 27 days (range from 12 to 83 days). All the donor areas of the thigh healed primarily. Follow-up time was 7 to 32 months, showing good color and texture. The sensation of the flaps recovered partially. Linear scars were left in all donor sites, except that one case suffereda large scar with no contracture or pain. One patient had an abnormal sensation in the incision area early but recovered gradually after two months without other serious complications. During the follow-up period, two cases of osteomyelitis showed no sinus, skin nonunion, and wound abscess. One case underwent a bone flap operation due to the bone defect one year later, and the defect healed well.Conclusions:Anterolateral femoral bilateral chimeric perforator flaps could be designed flexibly according to the conditions of the recipient area. By carrying the muscle with an abundant blood supply, the infection can be effectively controlled, and the damage to the donor area can be reduced.

Objective:To explore the feasibility and safty of robot assisted trans-diaphragmatic intropericardial inferior vena cava occlusion and thrombectomy in treatment of Ⅳa grade tumor thrombus without cardiopulmonary bypass and thoracotomy.Methods:The clinical data of 4 patients with renal cell carcinoma and Ⅳa grade tumor thrombus by robot assisted trans-diaphragmatic intropericardial inferior vena cava occlusion and thrombectomy from January 2013 to June 2019 were retrospectively analyzed. The median age was 53.5 (53-70) years. The average body mass index was 23.25 (20.7-26.3) kg/m 2. The tumors were located on the right side in 2 cases. The average maximum diameter of the tumor was 8.1 (3.6-11.2) cm.Preoperative tumor thrombus of all patients was classified as Ⅳa. The average preoperative length of tumor thrombus in vena cava was 12.3 (11.8-18.0) cm. All the operations were performed under multidisciplinary cooperation of urology, hepatobiliary, cardiovascular, ultrasound and anesthesiologist team. Surgical procedure: Robot assisted liver mobilization was used to expose the inferior vena cava. Under the guidance of intraoperative ultrasound, the central tendon and pericardium of diaphragm were dissected until the inferior vena cava and right atrium in the superior pericardium were exposed. The first porta hepatis and inferior vena cava were blocked in turn.The vena cava thrombectomy and inferior vena cava reconstruction were performed. Results:All the operations were completed without conversion. The median operation time was 553.5 (338-642) minutes, and the median time of the first porta hepatis occlusion was 18.1 (14-32)minutes. The median blood loss was 1 900(1 000-2 600)ml. All patients were transferred to ICU after operation. The median length of stay in ICU was 7(4-8) days, and the median time of indwelling drainage tube was 8(4-12) days. The average postoperative hospital stay was 13(11-20) days. There were 1 case of grade Ⅱ and 3 cases of grade Ⅲ complications (Clavien classification). One case had paroxysmal supraventricular tachycardia, one case had lymphatic fistula, one case had pleural effusion with atelectasis, and one case had hepatic and renal insufficiency and lymphatic fistula. The complications were improved after treatment. There was no perioperative death.Conclusions:Robot assisted trans-diaphragmatic intropericardial inferior vena cava occlusion and thrombectomy is an alternative method for the treatment of Ⅳa grade inferior vena cava tumor thrombus. Using this method, Ⅳa grade tumor thrombus can be treated without cardiopulmonary bypass and thoracotomy, with controllable complications and zero perioperative mortality.

Objective:To investigate the blood supply pattern and characteristics of bilobate anterolateral thigh flaps, and to summarize the clinical experience.Methods:Date of 102 cases of limb wounds repaired by bilateral anterolateral thigh perforator flaps from March 2014 to July 2019 were retrospectively analyzed. There were 80 males and 22 females with an average age of 40.7 years (range, 9-66 years). All of the patients suffered from limb trauma with complex tissue defects, among which 29 cases had two adjacent and discontinuous wound surfaces on the same limb, and the area ranged from 5 cm×5 cm to 30 cm×18 cm, while the other 73 cases remained a single wound with the area ranged from 12 cm×11 cm to 27 cm×15 cm. Ultrasonic Doppler was used to locate the perforating branches. According to different patterns of blood supply, flaps of different types were designed and applied respectively. For those who with perforating branches of common trunk type or fascial type, the wound surface can be covered by the flap directly; for those who with perforating branches of double trunks type or mixed type, the turbocharging technique was performed after dissection of the pedicles of the flap, while the wound was repaired by reconnection. All the donor sites were sutured directly.Results:Total of 105 bilobed flaps were designed in 102 patients, including 43 flaps of common trunk type, 30 flaps of double trunks type, 24 flaps of fascial type and 8 flaps of mixed type. The single harvested flap area ranged from 6 cm×5 cm to 20 cm×9 cm. One patient's one piece of the bilobed flap repairing two wounds suffered an arterial crisis at 17 h after surgery. The surgery confirmed there was an intractable arterial spasm and the crisis was relieved after a vein trans-plantation. Then about 4 cm×3 cm superficial necrosis appeared in the most distal part of the flap and healed in secondary after dressing changes. Two cases with single wounds suffered from a vein crisis at 48 h after operation. After removing the suture and blood letting, the flaps survived a week later. The average healing time was 19 days (range, 8-83 days). All the thigh donor sites healed by first stage. All the cases were followed-up for an average period of 16 month (range, 6-70 months). The latest follow-up showed that the flaps were of good color and texture, and the sensation of the flaps recovered partially. According to the British Medical Research Council sensory rating scale: 21 cases were grade S2 and 81 cases were grade S3. According to the revascularization assessments of digital replantation standard by Hand Surgery Branch of Chinese Medical Association, the results were excellent in 91 cases, good in 11 cases, with excellent and good rate of 100%. Linear scars were left in most donor sites and the VAS scores were all zero. 5 cases had a large scar area which the width was more than 3 cm, but there was no scar contracture or pain. 9 cases had an abnormal sensation in the donor area in the early stage and recovered gradually 3 months later without any movement disorder.Conclusion:The use of the bilobed anterolateral femoral perforator flap with different blood supply patterns to repair the wounds of extremities could overcome the lack or deficiency of blood supply caused by perforators with different sources. To clarify the blood supply types is conducive to the flap cutting and leaf splitting during the operation, which greatly improves the survival rate of the flap.

Objective:To compare the long term and short term outcomes between robotic and open surgery for hilar cholangiocarcinoma radical resection.Methods:This is a single-center and retrospective case-control study. Patients underwent hilar cholangiocarcinoma radical resection between January 2016 and December 2016 at Department of Hepatobiliary Surgery of the General Hospital of the Chinese People′s Liberation Army were included. Safety, effectiveness and long-term prognosis of tumors were evaluated. Patients were divided into robotic hilar cholangiocarcinoma radical surgery group (robotic group, n=16) and open hepatic hilar cholangiocarcinoma radical surgery group (open group, n=31) . All cases were confirmed by pathology histological. Age, gender, histology, resection margin status, extent of surgical resection, disease-free survival (DFS) , and overall survival (OS) were retrospectively collected and analyzed.In the follow-up cohort, the primary outcome was patient death and the secondary outcome was tumor recurrence. Continuous variables were expressed as means and medians and were compared using the Student t test if normally distributed or Wilcoxon-Mann-Whitney test for nonparametric variables. Discrete variables were expressed as frequency and percentages and χ 2 or Fisher exact test, when appropriate, were used for comparisons. Kaplan-Meier curves were used to calculate the probability of survival and comparisons were performed using log-rank test. Results:In this study, compared with the open group, the robotic group had a longer operation time ( (338±71) minutes vs. (256±56) minutes, t=4.251, P=0.001) , but the intraoperative blood loss was less (100 ml vs. 200 ml, Z=121.50, P=0.040) , the gastric tube removal time was earlier (3 days vs. 4 days, Z=136.0, P=0.011) , and the postoperative hospital stay was shorter (9 days vs. 12 days, Z=144.50, P=0.040) , and the difference was statistically significant.There was no significant difference in the blood transfusion rate, R0 resection rate, and tumor size between the two groups.The recurrence rates in the robotic group and open surgery were 53.3% and 67.0%, respectively (χ 2=1.04, P=0.307) .The median survival time of the robotic group and the open group was 22.0 months and 25.0 months. There was no significant difference in the overall survival rate between the two groups ( P>0.05) . Conclusion:Compared with laparotomy, robotic HCC radical resection could have an equivalence or non-inferiority approach with acceptable long-term outcome.

According to the pathological characteristics of symptomatic chronic thoracic and lumbar osteoporotic vertebral fracture (SCOVF), the different clinical treatment methods are selected, including vertebral augmentation, anterior-posterior fixation and fusion, posterior decompression fixation and fusion, and posterior correction osteotomy. However, there is still a lack of a unified understanding on how to choose appropriate treatment method for SCOVF. In order to reflect the new treatment concept and the evidence-based medicine progress of SCOVF in a timely manner and standardize its treatment, the clinical guideline for surgical treatment of SCOVF is formulated in compliance with the principle of scientificity, practicability and advancement and based on the level of evidence-based medicine.

Objective:To explore the clinical effect of bilobate anterolateral thigh flaps with turbocharging technique in repairing limb wounds.Methods:A retrospective case series study was conducted to analyze the clinical data of 29 patients with complex wounds of limbs admitted to Ruihua Hospital Affiliated to Soochow University from March 2014 to July 2019. There were 26 males and 3 females, aged 22-60 years [(41.9±11.1)years]. A total of 24 patients had single-wounds with the dimension of 12 cm×10 cm to 38 cm×27 cm, and 5 patients had two adjacent and discontinuous wounds with the area from 7 cm×4 cm to 13 cm×9 cm. The bilobate anterolateral thigh flaps with turbocharging technique were used. All the donor sites were directly sutured by primary closure. Routine treatment was given after operation. The origin artery of perforators, time of flap harvesting and operation time were recorded. The survival of the flap, healing of the donor area, long-term shape of the flap and donor area, sensory recovery and complications were observed.Results:All patients were followed up for 6-64 months [(19.0±12.7)months]. A total of 30 bilobed flaps were designed for the 29 patients. The time of flap harvesting ranged from 25 to 60 minutes [(46.6±20.2)minutes]. The operation time was 4-11 hours [(6.4±1.8)hours]. All flaps survived except one piece of a bilobed flap suffered from a vein crisis, which healed well after conservative treatment. These wounds' healing time ranged from 11 to 53 days [(18.5±9.9)days], and all the donor sites healed by first intention. Four patients underwent skin flap thinning operation 4 to 8 months later due to the bloated appearance of flaps. Acceptable cosmetic outcomes, soft and elastic skin, and sensation recovery were achieved at the final follow-up. All patients 'donor area left linear scars. One patient had large scar area, but there was no scar contracture and pain. Two patients had an abnormal sensation in the incision area in the early stage and recovered gradually 3 months later without any other serious complications.Conclusions:Repair of limb wounds with bilobed anterolateral thigh flaps with turbocharged technique can overcome the limitation that the bilobed flap can not be designed if the perforators do not share the same trunk and expand the application scope of the bilobed flaps. The design of bilobate flaps reduces the width of the donor site, which can effectively avoid the complications of the donor site.
