Objective To evaluate the cl inical effectiveness and advantages of one-stage posterior debridement, bone graft, and internal fixation for thoracic tuberculosis. Methods The data were retrospectively analysed, from 21 cases of thoracic tuberculosis undergoing one-stage posterior debridement, bone graft, and internal fixation between June 2007 andNovember 2009. There were 16 males and 5 females with an average age of 42.2 years (range, 22-73 years). The average disease duration was 13.2 months (range, 7-21 months). The lesions were located at the level of T5, 6 (1 case), T6, 7 (1 case), T8, 9 (4 cases), T9, 10 (3 cases), T10, 11 (5 cases), T11, 12 (6 cases), and T9-11 (1 case). According to the Frankel grading criterion, the neurological function was rated as grade B in 2 cases, grade C in 6 cases, grade D in 10 cases, and grade E in 3 cases. The preoperative Cobb angle was (26.3 ± 9.2)°. The erythrocyte sedimentation rate (ESR) was (35.9 ± 11.2) mm/ 1 hour. Results Thoracic tuberculosis was confirmed in postoperative pathological examination in all 21 cases. All incisions healed primarily without fistules formation. The average follow-up time for 21 patients was 16.2 months (range, 1-3 years). Bony fusion was achieved within 7-12 months (mean, 9 months) without pseudoarthrosis. No loosening and breakage of internal fixation were found, and no local recurrence occurred. The ESR decreased to (25.1 ± 8.9) mm/1 hour at 1 week postoperatively, showing significant difference when compared with preoperative value (t=5.935, P lt; 0.01); it decreased to (14.1 ± 4.6) mm/1 hour at 3 months postoperatively. According to Frankel grade, the neurological function was significantly improved at 1 year after operation (χ2=13.689, P=0.003). The average Cobb angle was (17.1 ± 4.5)° at 1 years postoperatively, showing significant difference when compared with preoperative value (t=7.476, P lt; 0.01). Conclusion One-stage posterior debridement, bone graft, and internal fixation has a good cl inical effectiveness for thoracic tuberculosis with less injury and complete focal cleaning, as well as a goodeffectiveness of spinal canal decompression and kyphosis deformity correction.
To explore the advantage and indication of combined anterior and posterior surgeries for lumbarsacral junction tuberculosis. Methods Eleven cases of the lumbarsacral junction tuberculosis were treated with combined anterior (radical debridement and autograft) and posterior (instrumentation and fusion) surgeries in one stage between January 2002 and December 2006. There were 9 males and 2 females with the age of 20-56 years old. The courseof disease was 4 to 15 months, 6 months on average. The lessons were located at L5, S1 in 7 patients, at L4,5, S1 in 2 patients and at L5, S2 in 2 patients. The involved vertebral bodies were at 2 segments in 7 patients; and 3 segments in 5 patients. The preoperative kyphosis was 5 to 8° with an average 9°. The sinus was associated in 3 patients, 3 patients had radiculopathy; 4 had paeumonophthisis and 9 had abscess. Results The followed-up period was from 6 months to 3 years, 18 months on average. According to Chen score, among the 11 cases, there were excellent in 9, good in 2. All incisions were healed up primarily. After operation, spinal fusion was achieved in 10 cases within 5 months to 7 months, 6 months on average, and pseudoarthrosis in 1 case was found by the CT examination. The postoperative kyphosis was 0 to 4° with the mean of 2° and the radiculopathy in 3 cases all got nerve function recovery. Conclusion Lumbarsacral junction tuberculosis treated with this surgical technique can achieve a high satisfactory rate with restoring the spinal stabil ity, arresting the disease early, providing early fusion, correcting the kyphosis and preventing progression of kyphosis particularly if lumbosacral spine tuberculosis is associated with sinus or preoperative diagnosis cannot exclude suppurative spondyl itis.
ObjectiveTo compare the effectiveness between the method of simple posterior debridement combined with bone grafting and fusion and internal fixation and the method of one-stage anterior radical debridement combined with bone grafting and fusion and posterior internal fixation in the treatment of thoracolumbar brucella spondylitis so as to provide the reference for the clinical treatment. MethodsA retrospective analysis was made on the clinical data of 148 cases of thoracolumbar brucella spondylitis between January 2002 and January 2012. Simple posterior debridement combined with bone grafting and fusion and internal fixation was used in 78 cases (group A), and one-stage anterior radical debridement combined with bone grafting and fusion and posterior internal fixation in 70 cases (group B). There was no significant difference in gender, age, disease duration, involved vertebral segments, erythrocyte sedimentation rate (ESR), visual analogue scale (VAS) score, neural function grade of America Spinal Injury Association (ASIA), and kyphosis Cobb angle before operation between 2 groups (P > 0.05). The peri operation period indexes (hospitalization time, operation time, and intraoperative blood loss) and the clinical effectiveness indexes (VAS score, ASIA grade, Cobb angle, and ESR) were compared; the bone fusion and the internal fixation were observed. ResultsIncision infection and paravertebral and/or psoas abscess occurred in 2 and 3 cases of group A respectively. All incisions healed by first intention and 2 cases had pneumothorax in group B. The operation time and the hospitalization time of group A were significantly shorter than those of group B (P < 0.05), and the intraoperative blood lossof group A was significantly lower than that of group B (P < 0.05). All of the cases in 2 groups were followed up 14-38 months, 25 months on average. The VAS, ESR, and Cobb angle were significantly decreased at each time point after operation when compared with preoperative ones in 2 groups (P < 0.05), but no significant difference was found between 2 groups (P > 0.05). The neurological function was significantly improved at 3 months after operation; there were 1 case of ASIA grade C, 14 cases of grade D, and 63 cases of grade E in group A, and there were 1 case of grade C, 11 cases of grade D, and 58 cases of grade E in group B; and difference was not significant (Z=0.168, P=0.682). The grafting bone fusion was observed in both groups. The fusion time was (8.7±0.3) months in group A and (8.6±0.4) months in group B, showing no significant difference (t=0.591, P=0.601) was found. At last follow-up, no loosening or fracture of internal fixation was found. ConclusionBased on regular medicine therapy, the effectiveness of the two methods is satisfactory in the treatment of thoracolumbar brucella spondylitis as long as the operation indications should be controlled strictly.

Objective To study the cl inical effects of modified Galveston technology in the treatment of lumbosacral tuberculosis. Methods From January 2001 to May 2008, 19 patients with lumbosacral tuberculosis were treated, including13 males and 6 females aged 21-58 years old (average 38 years old). The course of disease was 8-22 months. The tuberculosis was at the L4-S1 level in 3 cases, the L5, S1 level in 10 cases, the L5-S2 level in 5 cases, and the S1, 2 level in 1 case. Seven cases were compl icated with neural symptom of the lower l imbs, 3 cases of them were grade C and 4 cases were grade D according to the Frankel scale of nerve function. The preoperative JOA score of lower back pain was 5-22 (average 19). Six cases were compl icated with il iac abscess, 3 cases with psoas abscess, 3 cases with sacroil iac joint tuberculosis, and 2 cases with pulmonary tuberculosis. For 12 patients, the operation of modified Galveston internal fixation via the posterior approach, focus debridement via vertebral canal, and interbody fusion with autogeneous il iac bone fragment grafting was performed; for 7 cases, the operation of modified Galveston internal fixation via the posterior approach, vertebral lamina fusion with autogeneous il iac bone fragment grafting, and anterior focus debridement was performed. Results The incision of 18 cases was healed by first intention, and 1 case had sinus 3 weeks after operation and healed 3 months after operation. Nineteen patients were followed up for 12-82 months (average 21 months). There was no recurrence of the local tuberculosis, and the common toxic symptom of tuberculosis disappeared 6-12 months after operation. All the patients achieved bony fusion 4-6 months postoperatively, and 3 patients with sacroil iac joint tuberculosis achieved sacroil iac joint fusion. For those 7 patients with combinations of the neural symptomof the lower l imbs, the symptoms disappeared and their Frankel scales were improved to grade E. The JOA score of low back pain at the final follow-up was 22-29 (average 26). There was a significant difference between preoperation and postoperation (P lt; 0.05). Conclusion The modified Galveston technology is helpful to reconstruct the stabil ity of lumbosacral vertebrae, improve bony fusion rate, reduce the postoperative in-bed time.
To assist grassroots sonographers in accurately and rapidly detecting intussusception lesions from children's abdominal ultrasound images, this paper proposes an improved YOLOv8n children's intussusception detection algorithm, called EMC-YOLOv8n. Firstly, the EfficientViT network with a cascaded group attention module was used as the backbone network to enhance the speed of target detection. Secondly, the improved C2fMBC module was used to replace the C2f module in the neck network to reduce network complexity, and the coordinate attention (CA) module was introduced after each C2fMBC module to enhance attention to positional information. Finally, experiments were conducted on the self-built dataset of intussusception in children. The results showed that the recall rate, average detection accuracy (mAP@0.5) and precision of the EMC-YOLOv8n algorithm improved by 3.9%, 2.1% and 0.9%, respectively, compared to the baseline algorithm. Despite slightly increased network parameters and computational load, significant improvements in detection accuracy enable efficient completion of detection tasks, demonstrating substantial economic and social value.
ObjectiveTo evaluate the role of surgical resection on synchronous multiple pulmonary nodules identified difficultly in clinics.MethodsThe clinical data of 97 patients with synchronous multiple pulmonary nodules who received surgical resection between 2012 and 2019 in Hunan Cancer Hospital were retrospectively analyzed. There were 72 males and 25 females, aged 58.1±9.0 years. Among these patients, there were 78 patients with ipsilateral and 19 patients with bilateral pulmonary nodules. Clinicopathological parameters between main nodules and secondary nodules were evaluated. Perioperative morbidity was also assessed.ResultsThe operation was successfully completed on all patients for the ipsilateral and bilateral lesions. Totally, 71.1% of mian lesions was mostly removed by lobectomy, and the completion rate of video-assisted thoracoscopic surgery (VATS) was 69.1% (67/97); 80.4% of secondary lesions were mostly removed by wedge resection, and the completion rate of VATS was 71.1% (69/97). The incidence of grade 3 or higher complications after unilateral or bilateral surgery was 12.8% and 5.3%, respectively. Postoperative pathology confirmed that the main lesions were malignant in 65 patients (67.0%), mainly adenocarcinoma (63.1%), of which 43.1% were in the stage Ⅰ; 32 patients were benign, mainly tuberculoma (56.3%). There were 29 patients of malignant secondary lesions, 67 benign, and 1 both benign and malignant; the pathological agreement rate of primary and secondary lesions was 54.6% (lung cancer metastases in the lung and all the benign). When the primary lesion was malignant with its diameters of <3 cm, 3-<5 cm, 5-7 cm, >7 cm, the metastatic rate of secondary lesions was 42.5%, 15.8%, 20.0%, 0, respectively. When the primary lesion was malignant with lymph node metastasis, the probability of the secondary lesion being a metastatic tumor was higher than that without lymph node metastasis (46.7% vs. 30.0%, P>0.05). When the primary lesion was malignant and the primary and secondary lesions were located in the same lobe, the secondary lesions were more likely to metastasize (54.5%), while when they were located on different lobes on the same side or different sides, the secondary lesions were more likely to be benign (58.1%, 72.7%), and the possibility of metastasis was small ( 32.6%, 9.1%). When the primary lesion was benign and clinical differential diagnosis was difficult, the secondary lesion was benign.ConclusionFor synchronous multiple pulmonary nodules, the diameter of the primary lesion is large, the metastatic rate of secondary lesions tends to decrease. In ipsilateral synchronous multiple pulmonary nodules, especially with node metastasis, the risk of metastatic nodule increases. Bilateral surgical resection does not significantly increase the perioperative morbidity.
Objective To evaluate the cl inical significance of the combination of intensified anti-tuberculosis treatment, posterior transpedicular screw system internal fixation, intertransverse bone grafting, and anterior approach focus debridement for the treatment of thoracolumbar tuberculosis. Methods From January 2005 to December 2007, 20 patients with thoracolumbar tuberculosis (T10-L3) were treated. There were 13 males and 7 females aged 21-64 years old (average 44 years old). The course of disease was 3 months to 3 years (average 10 months). The focus involved single vertebrae bodies in 8 cases, two vertebrae bodies in 9 cases, and three vertebrae bodies in 3 cases. The preoperative Cobb angle was 9-35° (average 26.7°). The neurological function was evaluated according to the Frankel grading criterion, there were 2 cases of grade B, 5 of grade C, 7 of grade D, and 6 of grade E. Vertebral body defect index score: 9 cases of 1-2 points, 7 cases of 2-3 points, and 4 cases above 3 points. After receiving the systemic five-drug treatment of anti-tuberculosis for 2-3 weeks, the patients underwent the posterior transpedicular screw system internal fixation and intertransverse bone grafting, and then received tuberculosis focus debridement via anterior approach, nerve decompression, and bone grafting fusion. Results The time of operation averaged 210 minutes and the mean blood loss during operation was 650 mL. Postoperatively, 2 patients had mild belting sensation in their thorax and 2 patients had mild pneumothorax. Their symptoms rel ived 2-3 weeks later without specific treatment. All the patients were followed up for 12-23 months. X-ray films showed that all the patients achieved successful bony fusion 6-18 months after operation, and the Cobb angle was 7-21° (average 15.2°) 12 months after operation without aggravation. The Frankel gradingsystem was used to assess the postoperative neurological function, 1 patient in grade B before operation was improved to grade C after operation, 1 patient in grade B was improved to grade D, 1 patient in grade C was improved to grade D, 4 patients in grade B were improved to grade E, and 7 patients in grade D were improved to grade E. All of the incisions healed and erythrocyte sedimentation rate became normal 2 weeks to 3 months after operation. All the patients showed no obvious abnormity in l iver and kidney function. There was no recurrence of tuberculosis. Conclusion It seems that the systemic drug treatment of antituberculosis before and after operation, the thorough debridement of focus during operation, and the effective and rel iable wayto reconstruct for the spinal stabil ity are the key points for the treatment of spinal tuberculosis.
ObjectiveTo summarize the therapeutic effect and clinical significance of reduced volume lesion resection combined with drug therapy for end-stage alveolar hepatic echinococcosis.MethodClinical data of 46 patients with end-stage alveolar hepatic echinococcosis who received treatment of reduced volume lesion resection combined with drug therapy at Department of General Surgery of Qinghai Provincial People’s Hospital from March 2013 to October 2019 were retrospectively analyzed.ResultsAmong the 46 patients, 3 patients were lost to follow-up and 43 patients received follow-up. The follow-up time ranged from 3 to 79 months, with the median of 40 months. Fifteen patients died during the follow-up period, of which 5 patients with cerebral hydatid disease died during 16–36 months due to acute seizures and cerebral edema, 4 patients with multiple systemic metastases died during 9–36 months due to multiple organ failure, 2 patients with pulmonary echinococcosis died due to acute pulmonary embolism, 4 patients died in 2 years after operation due to recurrent biliary tract infection, other patients survived during follow-up period without distant organ metastasis.ConclusionReduced volume lesion resection combined with drug therapy in treatment of end-stage alveolar hepatic echinococcosis can improve the patient’s quality of life, reduce the hospital cost, reduce the occurrence of postoperative complications, and shorten the length of hospital stay.
