Objective To evaluate the efficacy of trans-obturator tension free vaginal tape(TVT-O)for the treatment of stress urinary incontinence(SUI)in women.Methods From January 2006 to September 2007,15 female patients with SUI received TVT-O in our hospital.A 1-cm longitudinal incision was made along the anterior wall of the vagina for the dissection of the urethra from the vaginal submucosal space to the obturator membrane.Then,a butteryfly-shape guide pole was inserted to guide the puncture of a spiral needle from the obturator membrane to the skin covering the root of the thigh.Afterwards,a trans-obturator tape was placed underneath the urethra without tension.Results The operation time was 15-40 min(mean,30 min),and blood loss was 10-40 ml(mean,20 ml).No intraoperative complication occurred in the series.One patient developed urinary retention,and was relieved by indwelling urethral catheter.Ten patients complained pain at the root of the thigh,and was cured simultaneously 3 to 10 days postoperation.Fifteen of the patients were followed up for 2 to 19 months with a mean of 8 months,during which no recurrence was found.Conclusion TVT-O is a simple,effective and reliable method for SUI.

[Objective]To evaluate clinical results of videoassisted thoracoscopic anterior spine release combined with anterior or posterior correction of adolescent idiopathic scoliosis(AIS).[Method]Eleven cases of received video-assisted thoracoscopic anterior spine release followed by anterior or posterior instrumentation from July 2003 to December 2005 were reviewed.The average age at surgery was 14.6 years(ranged from 12 to 16 years).There were nine cases of Lenke type Ⅰ with average preoperative Cobb's angle of 59.7?(ranged from 54? to 68?),and two cases of Lenke type Ⅲ,with average preoperative Cobb's angle of 64.5?(ranged from 58?to 71?).The correction rate of thoracic curves in bending film averaged 26.4%(ranged from 21.8% to 32.4%).All 11 patients underwent release via endoscopic anterior resection of intervertebra disc through radiofrequency,and anterior or posterior correction.The coronal and sagittal Cobb's angle after surgery,and at follow-up were measured.The operative time,intraoperational blood loss,peri-operative complications and loss of carrection were analyzed.[Result]The average operation time was 4 hours and 50 min.The blood loss during surgery averaged 171 ml.The average number of released levels was 4.4(ranged from 5 to 7).The average postoperative Cobb's angle of 9 cases of Lenke type Ⅰ was 20.4? with curve correction rate of 65.5%.Postoperative Cobb's angles of 2 cases of Lenke type Ⅲ were 20? and 25?,the correction rate of thoracic curve averaged 65.1%.One patient developed thoracic effusion.The average follow-up period was 18.6 months,only one of them with loss correction of 14?.No neurologic or vascular complication occurred.[Conclusion]Compared to the open anterior surgery,video-assisted thoracoscopic anterior spinal release is a safe and effective treatment for idiopathic scoliosis.It can avoid complications incurred by traditional thoracic surgery.It has satisfactory clinical results compared to conventional thoracotomic release for AlS.

Objective To investigate the effect of corpectomy decompression by subtotal vertebrectomy and fusion of adjacent segmental artificial disc replacement through anterior intervertenral spance (Hybrid Surgery) in the anteriorcervical spondylotic myelopathy treatment . Methods Hybrid Surgery were operated on 18 patients who suffered from anterior cervi?cal spondylotic myelopathy . Follow up of 1-50 months. Patient’s conditions were assessed according to the Japanese Associ?ation for Department of orthopedics assessment score (JOA score) before and after operation. Effects of Hybrid operation were assessed by the improvement of JOA score, Odom’s follow-up grade and cervical mobility . Results The JOA scores of all 18 operated patients were improved from 10.6 ± 1.7 before operation to 13.5 ± 2.4 after operation. And the difference is statistically significant (t=1.314, P < 0.05). Among all the operated patients, 16 were cured and 2 were effective. As to Odom’s follow up grades, 6 cases were excellent, 11 cases were good and 1 case was acceptable. The postoperative move?ment range of cervical spine (40.1° ± 8.4°) show no statistically difference compared with that in preoperation (42.6° ± 11.9°) (t=0.68, P > 0.05). Conclusion Hybrid Surgery of anterior cervical decompression and fusion can both improve the nerve function and preserve cervical mobility.

Objective To investigate the effect of perioperative pulmonary infection in elderly patients with mild to moderate chronic obstructive pulmonary disease (COPD) undergoing general anesthesia.Methods Forty elderly patients undergoing general anesthesia and abdominal surgery, 24 males, 16 females, aged 65-81 years, ASA physical status Ⅰ-Ⅲ, BMI 19-28 kg/m2, were randomly divided into two groups (n=20 each): protective ventilation group (group PV) and conventional ventilation group (group CV).Lung protective ventilation was received in group PV: intermittent positive pressure ventilation, tidal volume 6 ml/kg (ideal body weight), positive end expiratory pressure (PEEP) 5-10 cm H2O, alveolar recruitment maneuver every 30 minutes;conventional ventilation was received in group CV: intermittent positive pressure ventilation, tidal volume 10 ml/kg (ideal body weight), without using the PEEP and alveolar recruitment maneuver.Venous blood samples for interleukin 6 (IL-6) and interleukin-8 (IL-8) were taken at five different time points: before the anesthesia induction (T1), 2 h after mechanical ventilation (T2), at the end of operation (T3), 6 h (T4) and 24 h (T5) after operation.The clinical pulmonary infection score (CPIS) was recorded at before anesthesia, days 1, 3, 5 and 7 after surgery.The incidence of postoperative pulmonary inflammation was also recorded.Results There was no statistical difference in the two groups with respect to age, body mass index, ASA physical status, intraoperative volume of infusion, estimated blood loss, urine volume, mechanical ventilation time, operation method and IL-6, IL-8 levels at T1-T5.Compared with T1, the IL-6 and IL-8 levels in two groups at T2-T5 increased significantly (P＜0.05).Compared that before anesthesia, CPIS in group CV on postoperative days 1, 3 and 5 increased significantly (P＜0.05);compared with group CV, CPIS and the incidence of postoperative pulmonary inflammation in group PV reduced significantly on postoperative days 1, 3 and 5 (P＜0.05).Conclusion Lung protective ventilation can not reduce perioperative IL-6, IL-8 levels in laparotomy elderly patients with COPD, but it can reduce the incidence of pulmonary inflammation and pulmonary infection within 5 postoperative days.

Objective To observe the abnormality of gray matter volume and density in patients undergoing postoperative delirium (POD).Methods Forty-seven cases of aged patients, 26 males and 21 females, aged 60-75 years, ASA physical status Ⅱ or Ⅲ, were selected.On the third day after operation, cognitive function estimation was performed.The patients were assigned into group POD and group C according to whether POD occurred and brain magnetic resonance imaging (MRI) scanning was implemented.The discrepancy in gray matter volume and density between the two groups were compared using voxel-based morphometry method (VBM).Correlation analysis was performed between the corresponding parameters in the regions where notable differences between the two groups existed and minimum mental state examination (MMSE) score were found.Results Global gray matter volume of group POD was notably lower than that of group C (P<0.01).Cerebrospinal fluid volume of group POD was significantly higher than that of group C (P<0.01).Gray matter volume of bilateral frontal gyrus and right parahippocampus was remarkably reduced in group POD (P<0.001).Gray matter density of bilateral hippocampus and right parahippocampus decreased significantly (P<0.001).Right parahippocampal gray matter volume was positively correlated with MMSE score in POD patients (P<0.05).Conclusion Structural abnormality in frontal regions, hippocampus and parahippocampus may play an important role in pathogenetic and developing process of POD.Gray matter volume in the right parahippocampus may be one of reference index for POD severity.
