ABSTRACT
Objective:To investigate the clinical application of Grunenwald incision in cervicothoracic junction surgery.Methods:The clinical data of 25 patients with cervicothoracic junction tumor and 1 patient with cervicothoracic junction trauma in the single treatment group of Department of Thoracic Surgery, the Fourth Hospital of Hebei Medical University from December 2011 to September 2021 were analyzed retrospectively, including 19 males and 7 females, aged 9-73 years old. Among the 26 patients, there were 9 cases of upper mediastinal tumor, 6 cases of superior sulcus tumor, 4 cases of thyroid tumor invading the upper mediastinal, 4 cases of chest wall tumor, 2 cases of esophageal cancer combined with supraclavicular lymph node metastasis, and 1 case of foreign body penetrating injury at the cervicothoracic junction. Grunenwald incision or additional posterolateral thoracic incision, median sternal incision, neck collar incision were used in all patients. The degree of tumor resection was evaluated. The operation time, intraoperative blood loss, length of hospital stay were observed, and the postoperative follow-up was analyzed.Results:There was no perioperative death in the whole group. 14 cases were treated with Grunenwald incision alone, 6 cases with additional posterolateral chest incision, 4 cases with additional neck collar incision, and 2 cases with additional median sternal incision. The tumors were completely resection in 22 cases, palliative tumor resection in 3 cases, and complete foreign body removal in 1 case. Postoperative pathology included 4 cases of schwannoma; 3 cases of lung adenocarcinoma, thyroid cancer and myofibroblastoma, respectively; 2 cases of supraclavicular lymph node metastasis of esophageal cancer and lung squamous carcinoma, respectively; 1 case of large cell neuroendocrine carcinoma, metastatic carcinoma of the first rib after lung squamous cell carcinoma, ganglioneuroma, nodular goiter, hemangioma, well differentiated liposarcoma, vascular endothelial tumor and cavernous angioma, respectively. The operation time was 120-430 min, with a mean of(226.92±88.40)min. The intraoperative blood loss was 100-1 000 ml, with a mean of(273.46±196.34)ml. The length of hospital stay was 6-26 days, with a mean of(12.73±4.46 )days. 26 patients were followed up for 6-130 months, with a mean of(57.88±43.64) months. During the follow-up period, 6 patients died.Conclusion:Grunenwald incision can provide good exposure of the structures near the cervicothoracic junction, preserve the integrity of sternoclavicular joint, reduce shoulder deformity, and has advantages for patients with cervicothoracic junction tumors, high rib resection, and cervicothoracic junction trauma.
ABSTRACT
Objective:To analyze the therapeutic effect of medial gastrocnemius muscle flap transfer combined with induced membrane technique in repairing anterior medial Gustilo-Anderson type ⅢB injury of the middle and upper tibia accompanied by bone defect.Methods:A retrospective case series study was conducted to analyze 21 patients with anterior medial Gustilo-Anderson type ⅢB injury of middle and upper tibia accompanied by bone defectanterior medial tibial fractures admitted to Xijing Hospital，Air Force Military Medical University from April 2017 to January 2019. There were 15 males and 6 females，with the age of （38.6 ± 7.6）years （range，18-66 years）. After admission，all patients had bone defect repair and fixation and soft tissue defect repair using membrane induction technique in the first stage. The area of soft tissue defect ranged from 8.0 cm × 6.0 cm to 16.0 cm × 12.0 cm. The length of tibial defect was （5.5 ± 1.8） cm （ranged，3.5-11.0 cm）. The size of metastasis of medial gastrocnemius flap ranged from 12.0 cm × 8.0 cm to 22.0 cm × 13.0 cm. The survival rate of muscle flap was observed. One week after the wound was stabilized，skin grafting on the surface of muscle flap was performed at second stage. The graft survival was observed. The induced membrane technique was used to reconstruct bone defects at third stage. The infection index，lower extremity functional scale （LEFS） and Mazur ankle function score were compared before and at the last follow-up. The fracture healing and related complications were observed，and the lower limb function was evaluated by Johner-Wruhs scoring system at the last follow-up.Results:All patients were followed up for 11-26 months ［（18.4 ± 5.1） months］. The muscle flap transferred survived in all patients at first stage. The skin graft survived at second stage，and the wound healing time was 1-4 weeks ［（3.1 ± 0.5）weeks］. After the surgery at third stage，the healing time of bone fracture was （8.2 ± 0.7）months （range，6-10 months）. A significantly lowered level of infection was observed at the last follow-up compared to that before operation （ P < 0.01）. The LEFS and Mazur ankle function scores of the affected limb were （52.2 ±8.9）points and （75.2 ± 13.1）points at the last follow-up，significantly higher than those before operation ［（36.0 ± 5.6）points，（53.7 ± 14.6）points］ （ P < 0.01）. The soft tissue defect was repaired satisfactorily，and the broken ends of bone defects were healed at the last follow-up. Delayed bone union occurred in 3 patients，but no infection，osteomyelitis，foot drop or other complications occurred. According to Johner- Wruhs score，18 patients were rated as excellent，2 patients as good，1 patient as fair and 0 patient as poor，with the excellent and good rate of 95%. Conclusion:For patients with anterior medial Gustilo-Anderson type ⅢB injury of the middle and upper tibia accompanied by bone defect，transfer of medial gastrocnemius head muscle flap combined with induced membrane technique can effectively repair the injured limb，reduce infection and restore partial function of the lower limb，indicating that the procedure is an effective treatment strategy with satisfactory clinical results.

ABSTRACT
Objective To investigate the correlation between ICRU reference point dose and dosevolume parameters of organs at risk (OARs) under different bladder and rectal filling status in threedimensional conformal brachytherapy for locally advanced cervical cancer.Methods A total of 31 patients who received magnetic resonance imaging-guided three-dimensional conformal brachytherapy for cervical cancer in 96 fractions were enrolled.The ICRU rectal and bladder reference points were determined in the treatment planning system,and the doses at these points were recorded and compared with the dose-volume parameters of the rectum and bladder.The paired t-test was used to analyze the differences between them.Results Bladder DICRU was lower than bladder D0.1cm3 and D1 cm3 (P=0.000 and 0.000),higher than bladder D5 cm3 and D10cm3 (P=0.000 and 0.000),and similar to bladder D2 cm3 (P=0.345).Under the bladder filling status,bladder DICRU was lower than D2cm3.Rectal DICRU was lower than rectal D0.1 cm3 and D1cm3 (P =0.000 and 0.002),higher than rectal D5 cm3 and D 10 cm3 (P =0.000 and 0.000),and similar to rectal D2cm3 (P=0.058).The ICRU bladder and rectal reference point doses were positively correlated with corresponding D2 cm3.In the case of bladder volume ≥ 200 cm3,the ICRU bladder reference point dose underestimated bladder D2 cm3.In the case of rectal volume ≥ 37 cm3,the ICRU rectal reference point dose overestimated rectal D2 cm3.Conclusions In three-dimensional conformal brachytherapy,it is generally safe to use D2 cm3 as an index to evaluate OARs,but when the bladder or rectum is in an empty status,the ICRU bladder or rectal reference point doses should be considered.
ABSTRACT
Objective To investigate the dosimetric differences between Utrecht applicator and ring applicator in three-dimensional (3D) conformal brachytherapy for locally advanced cervical cancer.Methods Twenty-five patients with locally advanced cervical cancer were treated with magnetic resonance imaging-guided 3D conformal brachytherapy.Utrecht applicator and ring applicator were used interchangeably for 96 cycles.Patients were divided into two groups according to the type of applicator.Each group received 48 cycles of treatment, in which ring applicator was first applied for 26 cycles and Utrecht applicator was first applied for 22 cycles.High-risk clinical target volume ( HR-CTV) , width, thickness, and D90 at the point A level, D2 cm3 of organs at risk (OARs), V7 Gy , W7 Gy,A, V7 Gy ,A, and W/T7 Gy were evaluated and analyzed using paired t-test.Results There were no significant differences in HR-CTV and the width, thickness, and D90 at the point A level between the Utrecht group and the ring group ( P=0.487;P=0.340;P=0.857;P=0.921);there were no significant differences in D2 cm3 values of bladder, rectum, sigmoid, and bowel between the two groups ( P=0.136;P=0.802;P=0.985;P=0.458);there were no significant differences in V7 Gy and T7 Gy,A between the two groups ( P=0.076;P=0.435) .The Utrecht group had a significantly larger W/T7 Gy,A than the ring group ( P=0.002 ) .Conclusions Utrecht applicator is appropriate for patients with relatively large width and width/thickness ratio of HR-CTV at the point A level.
ABSTRACT
Objective To explore the role of severity of limb ischemic injury in the treatment of popliteal artery injury.Methods A retrospective analysis was conducted of 259 patients with popliteal artery injury who had been treated from January 2002 to December 2014.They were 187 males and 72 females with a median age of 37.6 years (range,from 14 to 68 years).The time from injury to revascularization was from 4 hours to 29 days.According to the Rutherford classification system,the limb ischemic injury was categorized into 4 grades:grade Ⅰ:presence of sense and motion;grade Ⅱ:presence of sense but loss of active motion;grade m:loss of sense or motion;grade Ⅳ:stiffness.For all the patients with injury of grades Ⅰ and Ⅱ,limb salvage was adopted and opening decompression to osteofascial compartment was performed depending on the intraoperative and postoperative limb swelling.For the patients with grade Ⅲ injury,opening decompression to osteofascial compartment was performed to explore the activity of muscles in those with a strong will to preserve their limbs.When the muscle activity was poor but bright red bleeding was found at the broken muscle ends and there were no fish-like changes in muscles,limb salvage was suggested;otherwise amputation was chosen.For all the patients with grade Ⅳ injury,amputation was suggested.Results Of the 146 cases of limb salvages,142 were successful and 4 failed due to uncontrollable infection,giving a total success rate of 54.83％ (142/259).Complete rupture of the popliteal artery occurred in 23 cases,incomplete rupture or tear in 17,contusion and thrombosis in 219.No patient died due to popliteal artery injury or its complications.The patients with injury of grades Ⅰ,Ⅱ,Ⅲ and Ⅳ were respectively 51,88,67 and 53;their success rates of limb salvage were respectively 100.00％ (51/51),96.59％ (85/88),8.96％ (6/ 67) and 0.For the patients whose time from injury to revascularization was ＜ 6 h,6 h to 12 h,13 h to 24 h,25 h to 1 w,and ＞ 1 w,the success rates of limb salvage were respectively 80.77％ (42/52),54.58％ (73/134),20.51％ (8/39),33.33％ (6/18),and 81.25％ (13/16).The 142 patients whose limbs had been salvaged obtained an average follow-up of 31.4 months (range,from 6 months to 8 years).Of them,those with grade Ⅰ injury obtained normal plantar sensation and active ankle flexion and extension.Of the 85 patients with grade Ⅱ injury,all recovered normal or nearly normal plantar sensation,29 achieved partial recovery of active ankle and digital flexion and extension,but the other 56 obtained no recovery of active ankle motion.Of the 6 patients with grade l injury,none obtained recovery of motion function,4 achieved partial recovery of plantar sensation but the other 2 had no recovery.Conclusion The classification of popliteal artery injury into 4 grades according to its severity of ischemic injury can provide helpful guidance to the treatment and prognosis assessment of the popliteal artery injury.
ABSTRACT
BACKGROUND:Bone cement containing antibiotics for repair of bone defects can achieve sustained release of a higher concentration of sensitive drugs, which wil help kil bacteria and provide the necessary bone grafting bed and space to reduce massive bleeding due to removal of the granulation at bone defects during the second phase. OBJECTIVE:To analyze the clinical efficacy of antibiotic bone cement combined with autologous bone transplantation and Ilizarov external fixator on tibial bone defects after traumatic osteomyelitis. METHODS:A total of 31 patients with tibial bone defects after chronic osteomyelitis, including 19 males and 12 females, aged 17-40 years old. After positive debridement of necrotic tissues at bone stump, Ilizarov external fixator was used for fracture fixation, and autogenous iliac bone grafting combined with bone cement containing antibiotics was performed to repair bone defects. Fracture healing time, knee and ankle scoring were fol owed up. RESULTS AND CONCLUSION:The 31 patients were fol owed up for 6 months to 3.5 years. Tibial fractures were healed without infection recurrence in al patients. The bony union time was 3-6 months, the fixation time was 3-6 months, and the limb extended length was (7.50±1.01) cm. No adverse reactions related to bone cement and bone graft occurred. At 3 months after bone grafting, the scores on the knee and ankle joints were improve significantly. These findings indicate that the antibiotic bone cement combined with autologous bone transplantation and Ilizarov external fixator for repair of post-osteomyelitis posterior tibial bone defects can control infection, promote fracture healing, and restore joint functions.
ABSTRACT
Objective To explore the correlation between the dose measured in the rectum and reference dose in three?dimensional brachytherapy ( 3DBT ) for cervical cancer, and to evaluate the significance of the dose measured in the rectum. Methods Fifty patients receiving radiotherapy for cervical cancer were selected, and 3DBT was performed after pelvic external beam radiotherapy. According to the rectal monitoring method recommended in the report ICRU38, in vivo monitoring was applied to obtain the dose measured in the rectum, reference point dose ( DICRU ) , and D2 cm3 , and the planned dose was obtained from the planning system. The differences in these values were determined by the paired t?test and correlation analysis was performed with Pearson test. Results The dose measured in the rectum was higher than the planned dose (3. 48 vs. 3. 25,P=0. 000), and lower than DICRU(3. 48 vs. 3. 71,P=0. 000) and D2 cm3(3. 48 vs. 3. 87,P=0. 002). A linear relationship existed between the dose measured in the rectum and the planned dose, with a deviation percentage of-20% to 40% and an average deviation of 8. 16%;63%of the patients with cervical cancer had a deviation of<± 10%;the maximum deviation was 60%. The dose measured in the rectum had a strong correlation with DICRU(r=0. 722), but a weak correlation with D2 cm3 ( r=0. 284) . Conclusions During 3DBT for cervical cancer, the dose measured in the rectum has certain deviations, but has a linear correlation with the planned dose. Both the dose measured and the planned dose underestimate the dose at the reference point in the rectum, and in vivo rectal monitoring may be an effective method for quality control.
ABSTRACT
Objective To compare target volume and dosimetry between computed tomography (CT)?and magnetic resonance imaging (MRI)?guided three?dimensional (3D) conformal brachytherapy for locally advanced cervical cancer, and to provide evidence for optimization of the image?guided approach and improvement of treatment regimen. Methods Thirteen patients with locally advanced cervical cancer who were treated with radical radiotherapy in our hospital in 2014 were enrolled as subjects. All patients received MRI?guided 3D conformal intracavitary/ interstitial brachytherapy. All patients received MRI and CT scans for each brachytherapy fraction, based on which the target volume delineation, intracavitary/ interstitial regimen design, and intracavitary?only treatment regimen design were performed. Comparison of data between MRI and CT scans was performed using paired t test. Results The width and volume of the high?risk clinical target volume ( HR?CTV) were significantly smaller in the MRI simulation than in the CT simulation ((38.0±9?? 4) mm vs. (45.1±8?? 7) mm, P= 0?? 000;(34.2±15?? 3) cm3 vs. (42.9±20?? 4) cm3 , P= 0?? 002), and the width, thickness, and volume of the intermediate?risk clinical target volume (IR?CTV) were also significantly smaller in the MRI simulation than in the CT simulation ((58.8±9?? 4) mm vs. (65.4±10?? 3) mm, P= 0?? 000;(34.8±6?? 3) mm vs. (37.5±6?? 3) mm, P= 0?? 001;(90.9±28?? 5) cm3 vs. (109.0±36?? 4) cm3 , P= 0?? 000). The D90 values for HR?CTV and IR?CTV were significantly higher in the MRI simulation than in the CT simulation (87?? 6 Gy vs. 85?? 8 Gy, P= 0?? 013;67?? 7 Gy vs. 66?? 3 Gy, P= 0?? 005), while the average D2 cm3 values for the bladder and rectum were significantly lower in the MRI simulation than in the CT simulation ( 73?? 1 Gy vs . 75?? 5 Gy , P= 0?? 011 ; 61?? 0 Gy vs . 65?? 7 Gy , P= 0?? 000 ) . Conclusions Compared with the MRI simulation, the CT simulation overestimates the width of target volume. MRI has substantial advantages in dosimetry for target volume and normal tissues. The intracavitary/ interstitial treatment can make up the reduced dose for the target volume resulting from the CT simulation.
ABSTRACT
Objective To analyze the outcome of the flow-through anterolateral thigh flap for reconstruction in the Gustilo type Ⅲ C traumatized extremities.Methods From June 2008 to June 2011,sixteen flow-through anterolateral thigh flaps were used for limb salvage.All in this series suffered from Gustilo type Ⅲ C open fractures in upper (4 cases) or lower extremities (12 cases).All patients had the presence of wide segmental soft tissue defects and segmental artery defects with compromised circulation.Four patients received primary operations and 12 patients received debridement combined with vacuum sealing drainage and secondary operations.Results All patients were followed up from 12 months to 40 months (average of 22 months).The mean age was 37.5 years old (from 18 to 62 years).The mean timing of free flap transfer was 6.7 days after injury (from 5 hours to 16 days).The mean artery defect was 12 cm in length (from 6 to 16 cm).All the flaps survived completely with a soft tissue texture.After operation,infection occurred in one patient,venous thrombosis occurred 1 day post-operatively in one patient,local flap necrosis occurred in two patients.No donor site morbidity was noted.In the last follow-up,according to Johner-Wruhs and Berton scores,the overall excellent/good rate for lower and upper extremities were 83.3％ and 75.0％ respectively.Conclusion Flow-through anterolateral thigh flaps provide for reconstruction of both the vessels and soft tissue simultaneously.Because of avoiding sacrificing one of the major vessels,it particularly indicates for only one major artery survival in the extremity.The clinical results show that the above reconstruction technique is useful for upper and lower extremities salvage.

ObjectiveTo explore the clinical effects of cold therapy in treatment of inflammatory hemorrhoids.MethodsSixty patients were separated into two groups according to the visiting sequence with 30 cases each.The treatment group accepted cold therapy,meanwhile the control group took the tablets diosmin and accepted hot compress with 50％ magnesium sulfate.ResultsThe symptoms evaluation score was ( 10.5 ± 1.3 ) scores and (6.4 ± 1.2) scores before and after treatment in treatment group,while ( 10.3 ±1.4) scores and(9.4 ± 1.3) scores in control group,there was no significant difference before treatment between two groups (P＞ 0.05 ),but there was significant difference after treatment between two groups (P＜0.05).After 3 days treatment,cure rate was 60.0％(18/30),eifficient rate was 90.0％(27/30) in treatment group,while 10.0％ (3/30),53.3％ ( 16/30 ) in control group,there were significant differences between two groups(P＜ 0.05).ConclusionCold therapy is good for inflammatory hemorrhoids.
ABSTRACT
Objective To investigate the clinical results of the anterolateral thigh free flaps for the soft tissue coverage of Gustilo grade-Ⅲ B open bone fractures in lower extremities.Methods The anterolateral thigh free flaps were applied to treat 42 Gustilo grade-11Ⅲ B open fractures.Ten flaps were performed through an emergency procedure.Sixteen were performed at early stage and the other 16 were performed at later stage .The results of the therapy were analyzed after long time follow up. Results All limbs were salvaged and all the flaps survived without protracted course to obtain soft tissue coverage.The follow up ranged 11 to 47 months.The healing time of the bones were significant prolonged in the later stage therapy group compared with the emergency therapy group and the early stage therapy group.In the later stage therapy group,the incidences of the bone infection and nonunion were also higher than the other two groups,and the second stage bone transplantation to repair bone defect and nonunion were needed in 76% patients in this group.The lower limb functions of the later stage treated group were worse than those of the other two groups.Compared to the early stage treated group,better lower limb functions could be obtained in the emergency treated group. Conclusion Delayed soft tissue coverage resulted in higher incidence of complications.The immediate soft tissue coverage of severely injured limbs complicated by Gustilo grade-Ⅲ B open fractures and massive soft tissue defects had the advantages over traditional methods.Hard work though it was,one-stage soft tissue coverage using anterolateral thigh free flaps could obtain better lower limb function.
ABSTRACT
@#Objective To investigate the feasibility and curative effect of botulinum toxin type A(BTX-A)point injection under the guidance of type-B ultrasonic on upper limb spasticity after stroke.Methods 18 cases were divided into two groups:9 cases for treatment group were treated with point injection BTX-A in 5 points with the guidance of type-B ultrasonic diagnosis,other 9 cases for control were only injected experientially.They were evaluated with the modified Ashworth scale(MAS)and the time taking effect were recorded.Results Compared with the control,the scores of MAS in the treatment group improved,and they came into effect more quickly(P<0.05).Conclusion The point injection of BTX-A under the guidance of type-B ultrasonic was practicable for and effective on upper limb spasticity after stroke.
