Objective To explore the diagnostic methods, therapy and the prognostic factors for the ruptured abdominal aortic aneurysm (RAAA). Methods The clinical data of 23 patients (males 15, females 8, age range 35-78, mean age 65) with RAAA below the level of renal arteries, who were treated with surgery, were collected from April 1999 to December 2005 and were analyzed retrospectively. Seven cases had a history of RAAA, 6 cases had pulsating abdominal masses; 15 cases were diagnosed by emergency Doppler ultrasonic examination or CT. All of the patients underwent emergency surgical operation: The ruptures of the abdominal aorta below the level of renal arteries were obstructed by using clamp ring or using transluminal ballon according to conditions of each patient. The aritficial vascular graft was then taken after the control of hemorrhage. Results There were 9 (39%) patients died within 30 d after the emergency operation. The causes of death included acute renal failure because of hemorrhagic shock (4 cases), multiple organ failure (3 cases), and respiratory-circulatory failure (2 cases).Conclusion Surgery may be an effective treatment for RAAA. The critical step of the operation was to control hemorrhage by obstructing the proximal end of the aortic rupture according to the conditions of each patient. The main postoperative complications and causes of death include acute cardiovascular and cerebrovascular diseases, renal failure and pneumonia.
Objective To investigate the surgical effect on different types of spinal canal stenosis of retrograde degeneration. Methods The retrospective analysis was performed on 96 patients (85 males, 11 females; average age 54, range 39-71) admitted from September 2001 to January 2004 for spinal canal stenosis of retrograde degeneration. The patients were divided into five groups according to their clinical symptoms and signs and the imaging of the spinal cord. In group A, 39 patients had one segment of the spinal canal stenosis and they underwent the recessively expanding operation through the intervertebral canal by opening a window between the vertebral plates. In group B,21 patients had stenosis of the central vertebral canal of one segment and theyunderwent excision of the intervertebral disc through the window opened betweenthe vertebral plates and the recessively expanding operation.In group C, 18 patients had degenerative spinal derangement of one segment and they underwent decompression through the window opened between the bilateral vertebral plates and the recessively expanding operation, and then underwent the internal fixation and bone grafting. In group D, 11 patients had the mixed stenosis of the vertebralcanal of more than 2 segments and they underwent the recessively expanding operation through the window opened bilaterally on the diseased segment and excisionof the yellow ligament and the intervertebral disc. In group E, 7 patients had degenerative lateral curvature of the spine and they underwent the combined surgical procedures including decompression, internal fixation, and bone grafting. All the patients were followed up after operation. Results The follow-up of the 96 patients for 6-36 months with an average of 12.2 months showed that they had no postoperative complications. According to the JOA Scoring,85 patients had an excellent result, 9 had a good result, 1 had a fair result, and only 1 had a poor result. The X-ray films revealed no mistaken placing of the nails on the vertebral arch, broken nails or loosened nails. Conclusion The limited surgery and effective decompression can improve curative effects and reduce complications of spinal canal stenosis of retrograde degeneration. The imaging of the spinal cord has an important value in the choice of surgical protocols for spinal canal stenosis of retrograde.
OBJECTIVE: To study the effects of jaw advancement in treating micromandibular deformity associated with obstructive sleep apnea syndrome (OSAS) by ramus osteotomy and genioplasty. METHODS: From April 1998 to February 2002, 12 patients with micromandibular deformity associated with OSAS (aged 14-36 years, 7 females and 5 males) were treated. Invert "L" shape ramus osteotomy and inverted replantation of posterior segment of ramus were performed to reconstruct the TMJ with the jaw advancement and genioplasty at the same time in 7 cases; mandibular angle osteotomy, bone grafts and genioplasty in 3 cases; and the jaw advancement by ramus sagittal osteotomy and genioplasty in 2 cases of the first branchial arch syndrome. RESULTS: The follow-up period was 6 months to 4 years. All the patients gained good appearance and had the distance of opening movement over 3.0 cm. Micromandible and facial asymmetries were corrected satisfactorily. The ratio of SaO2 was ascended from 82%-92% (preoperation) to 97%-99% (postoperation). OSAS was relieved. CONCLUSION: The jaw advancement by ramus osteotomy and genioplasty for treating micromandibular deformity associated with OSAS can correct the maxillofacial deformities and enlarge the upper airway space to relieve OSAS. This method has achieved satisfactory result.

Methods Domestic and abroad literature concerning the minimally invasive technique applied in calcaneus fractures in recent years was reviewed extensively and analyzed thoroughly. Results There are both advantages and limitations of each minimally invasive technique including percutaneous reduction and fixation, limited incision, external fixator, arthroscopic assisted reduction, and balloon expansion reduction. But every technique is developing rapidly and becoming more and more effective. Conclusion A variety of minimally invasive technique can not only be used independently but also can be applied jointly to complement one another. It needs further study how to improve the effectiveness and expand the indications. And the theoretical basis of evidence-based medicine needs to be provided more.
Abstract: ObjectiveTo explore the surgical characteristics of primary tracheal tumors treatment and its prognosis. Methods [WTBZ]We retrospectively investigated the clinical records of 38 patients with primary tracheal tumors in both Xiangya Hospital of Central South University and Hunan Provincial Tumor Hospital from Febuary 1982 to August 2009. There were 24 males and 14 females aged from 7 to 65 years. There were 2 benign lesions, 13 adenoid cystic carcinomas, 11 squamous cell carcinomas, 5 mucoepidermoid carcinomas, 4 adenocarcinomas and 3 other cell types. One patient with adenocarcinoma underwent exploratory thoracotomy only; 33 patients underwent tracheal resection and airway reconstruction, and according to the tumor growth characteristics, the surgeon applied circumferential tracheal resection with endtoend anostomosis or wedge resection; One patient had papilloma resected under fiber bronchoscopy; and three patients with locally advanced lesions underwent radiotherapy without surgery. The overall survival rate was calculated by the KaplanMeier method. The logrank method was used for comparing survival rates among different groups, characterized by cell types or surgical procedures. Results [WTBZ]The patient with exploratory thoracotomy died 3 days after surgery from respiratory failure. The perioperative mortality was 2.94% (1/34), and all the remaining 33 patients recovered and were discharged from hospital. Minor complications happened to 12 patients (35.29%), including 6 patients with pulmonary infection, 4 with atelectasis, and 2 with hoarseness. The followup time ranged from 6 months to 15 years. The followup rate was 97.29% (36/37). The threeunresected patients died within 6 months after hospital discharge. The 1, 5, and 10year survival rate for resected patients was88% （95%CI 0.77 to 0.99), 47%(95%CI 0.29 to 0.66), and 41% (95%CI 0.21 to 0.61), respectively. The survival rate of adenoid cystic carcinoma or mucoepidermoid carcinoma was significantly higher than that of squamous cell carcinoma or other tissue types (χ2=17.581, P=0.001). There was no statistical difference (χ2=0.021, P=0.886) in 5 year survival rate between wedge resection group at 63%(95%CI 0.34 to 0.91) and the segmental resection group at 77%(95%CI 0.44 to 0.99). Conclusions [WTBZ]Surgical treatment is safe and beneficial for primary tracheal tumors, and the pathological type is a significant prognostic factor after complete resection.
Objective To explore the indications for liver transplantation among patients with hepatolithiasis. Methods Data from 1431 consecutive patients with hepatolithiasis who underwent surgical treatment from January 2000 to December 2006 were retrospectively collected for analysis. Surgical procedures included T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones, hepatectomy, cholangiojejunostomy, and liver transplantation. Results Nine hundred and sixty-one patients who had a stone located in the left or right intrahepatic duct underwent hepatectomy or T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones. The rate of residual stones was 7.5% (72/961). Four hundred and seventy patients who had a stone located in the bilateral intrahepatic ducts underwent surgical procedures other than liver transplantation; the rate of residual stones was 21.7% (102/470). Only 15 patients with hepatolithiasis underwent liver transplantation; they all survived. According to the degree of biliary cirrhosis, recipients were divided into 2 groups: a group with biliary decompensated cirrhosis (n=7), or group with biliary compensated cirrhosis or noncirrhosis group (n=8). There were significant differences in operative times, transfusion volumes and blood losses between 2 groups (P＜0.05). In the first group, 6 of 7 patients experienced surgical complications, and in the second, 8 recipients recovered smoothly with no complications. Health status, disability and psychological wellness of all recipients (n=15) were significantly improved in 1 year after transplantation as compared with pretransplantation (P＜0.05). Conclusion Liver transplantation is a possible method to address hepatolithiasis and secondary decompensated biliary cirrhosis or difficult to remove, diffusely distributed intrahepatic duct stones unavailable by hepatectomy, cholangiojejunostomy, and choledochoscopy.
Objective To investigate the surgicalmethod and perioperative treatment for senile lumbar disease accompanied by internal disease. Methods From June 2000 to December 2003,the complete neurological and physical examinations were performed on the patients before operation, as treatment of internal diseases could improve the patients’ conditions. Lumbar operations were performed on 125 patients, among whom 23 had simple lumbardisc herniation, 13 had lumbar spine stenosis, 81 had lumbar disc herniation with lumbar spine stenosis, and 8 had spondylolisthesis.The JOA score was 116±2.5. There were 3 patients undergoing fenerstration+discectomy, 16 undergoing semilaminectomy+discectomy,82 undergoing total-laminectomy+disectomy, 5 undergoing total-laminectomy+disectomy+pedicle fixation, 11 undergoing lamina decompression+nerve-root pathyway decompression, and 8 undergoing pedicle screw fixation+bone graft and fusion in spondylolisthesis. Results With an effective medical treatment, the internal disease produced little effect on the operation. Improved functions and bone fusions were observed after- operation. According to the JOA standards, the average alleviation rate was 87.9%. Conclusion Early neurological examination and proper treatment of internal diseases are the keys to the successful operation on the senile patients with lumbar disease. Radiological data are important in avoidance of mistaken diagnosis.
OBJECTIVE: To report the effect of Russe technique in treating old scaphoid fracture. METHODS: From January 1987 to February 1999, 11 cases of old scaphoid fractures were treated with Russe technique. The follow-up period averaged 5 years and 7 months. RESULTS: The fracture healing rate was 100%, and wrist pain was completely relieved in all cases. The ranges of motion averaged 41.2 degrees of flexion, 40.5 degrees of extension, 8.7 degrees of radial deviation, and 15.4 degrees of ulnar deviation. The grip strength reached 82.9% of the normal side. CONCLUSION: Russe technique is an effective and safe method of treatment for old scaphoid fracture.
Objective To reinforce the recognization of deltoid contracture inchildren and probe its causes, pathomechanism,diagnosis and treatments. Methods The Clinical data were summarized and analysed, including etiological factors, clinical situations, examinations and treatments from 9 child patients with deltoid contracture from 1992 to2004. The 9 child patients were followed up to evaluate therapeutic efficacy. Results Nine child patients with deltoid contractureincluded 4 boys and 5 girls, who aged from 5 to 14 years. The main clinical features were presented as abductive deformity,limitation of adduction of the shoulder, winging of the scapula, and dimpling of the skin with a palpable fibrous hard band in deltoid muscle. Four cases had a history of intramuscular injections in deltoid and 1 case was accompanied with bilateral gluteul contracture.Among the 9 patients, 8 cases were misdiagnosed before correct diagnosis and treatment. The misdiagnosis rate was up to 90%. All the cases received the operative treatments to release fibrous bands and were followed up for 8 months to 12 years. Abductive deformity disappeared and functions of the shoulders recovered inall patients, except 1 patient who had a lightly winged scapula. Conclusion Deltoid contracture may be caused by multiple factors,but its clinical features are conductive to correct diagnosis and excellent therapautic efficacy can be acquired by operation early.
Objective To summarize the experience of the surgical treatment of total anomalous pulmonary venous connection (TAPVC) in 31 cases，so as to elevate the operative effect. Methods The total corrected operation under moderate hypothermic cardiopulmonary bypass were performed in 31 cases with TAPVC. Site of drainage was supracardiac (n=16),cardiac(n=13)and mixed(n=2). Other accompanying congenital cardiac malformations were diagnosed such as atrial septal defect(n=31), patent ductus arteriosus(n=4), pulmonic stenosis(n=1), mitral regurgitation(n=1), tricuspid regurgitation (n=15)，etc. Results No hospital death was observed in the early period of operation (30 d). Complication occurred in 8 cases (25.8%), such as paroxysm of nodal rhythm(n=1), Ⅰ° atrial ventricular block(n=1), frequently atrial premature beats and paroxysm of auricular tachycardia(n=1),pulmonary infection(n=2),atelectasis(n=1), pneumatothorax (n=1), left diaphragmatic paralysis and pulmonary infection with tracheal reintubation (n=1),etc. All of them discharged after active therapy. All of 31 cases was followed up, followup time was 2.8±1.5 years. 30 cases were living (96.7%) and 1 case died of heart failure 8 months after operation. 2 cases had auricular arrhythmia with a bad medical effect. 28 cases(93.3%) had normal heart function and they could work and live normally after discharged. Conclusion Surgical procedure should be based on individual abnormality for TAPVC.Surgeons should take care not only of the stenosis of anastomotic stoma,but also of the arrhythmia after operation.Satisfied correction of the abnormality is important and the curative effect of those cases is approving.
