Objective: To evaluate the impact of esophagectomy and palliative treatment on short term and long term quality of life (QL) in patients with esophageal cancer. Methods: 88 consective patients treated with radical esophagectomy or palliative treatment were scored by European organization of cancer research and treatment (EORTC), QLQ C30 measurement of QL before treatment and at regular intervals until death or 3 years after operation. The cases were divided into 3 groups and mean scores were obtained from each group. Patients surviving more than 2 years were classified as group 1, with group 2 surviving less than 2 years, and group 3 undergoing palliative treatment. Results: Baseline functional and symptomatic QL scores were similar before treatment in the first and second group, which were higher than scores from the third group. Six weeks after esophagectomy, patients reported worse functional, symptom and global QL scores than before treatment. In the first group, QL scores returned to preoperative level within 9 months. However, improved symptom of dysphagia the second group never regained their former QL scores apart from dysphagia improved after surgery. QL scores of the third group were similar to those of the second group after treatment. Conclusion: Esophagectomy might have a negative impact on patients QL. This effect was found to be transient in the first group but inreversible in the second group. It might seem reasonable for patients in late stage to be treated palliatively.

Objective [WT5”BZ]To evaluate the interventional therapy for Budd Chiari syndrome in which inferior vena cava was segmentally stenotic or occlusive combined with obstruction of hepatic vein and thrombosis.[WT5”HZ] Methods [WT5”BZ] 13 cases with regional stricture or occlusion in inferior vena cava (8 cases with hepatic vein occlusion and 5 cases with thrombosis of inferior vena cava) were reviewed and the length of lesions ranged from 2?cm to 5?cm. For patients with IVC occlusion, atrial septum puncture was used, followed by 1 0~2 0?cm balloon dilation and implantation of metal stent. For patients with hepatic vein occlusion, RUPS 100 liver puncture apparatus was applied and followed by 0 5~1 0?cm balloon dilation. Postoperative anticoagulant therapy was used for 3 months.[WT5”HZ] Results [WT5”BZ]Procedures were successful in all cases. Shrinkage of the spleen and absorption of ascites were observed after operation. There were no relapse of symptoms, nor digestive tract bleeding during 3~26 months of follow up. [WT5”HZ]Conclusions [WT5”BZ] Thrombolytic therapy was very important before the repatency of the IVC for patients with thrombosis formation. The embedded in stent must be away from the orifice of accessory liver vein. Angioplasty of hepatic vein is essential for the interventional treatment of Budd Chiari syndrome. [WT5”HZ]

Objective:To explore the ability of training on a three-dimensional motion platform to improve the walking ability and skill in the activities of daily living of hemiplegic stroke survivors.Methods:A total of 70 stroke survivors with hemiplegia were randomly divided into a control group ( n=35) and an intervention group ( n=35). In addition to routine rehabilitation, the control group received 40 minutes of ground balance training, while the intervention group received 40 minutes of training on a three-dimensional motion platform 6 times a week for 4 weeks. Before and after the intervention, step length, speed and frequency were evaluated in both groups using the Gait Watch 3D gait analysis system. Walking ability and ability in the activities of daily living were assessed using the de Morton mobility index (DEMMI) and the modified Barthel index (MBI). Results:Before the treatment, there was no significant difference in average step length, speed or frequency between the two groups. The average standing phase percentage on the affected side, percentage of double support period, DEMMI score, and MBI score also were not significantly different. After the treatment those indicators had improved significantly in both groups. The intervention group′s averages were then all significantly better than those of the control group.Conclusions:Three-dimensional motion platform training can improve the walking ability and skill in the activities of daily living of hemiplegic stroke survivors.

Objective:To explore the safety, feasibility, and short-term outcome ofdistraction on the concave side in the treatment of patients with congenital cervical scoliosis.Methods:Between August 2015 and December 2019, 11 patients with congenital cervical scoliosis underwent distraction technique on concave side, among which 5 were males and 6 were females. Age was 9.9±3.1 years old (range 6-16 years old). The primary cervical spine deformity was hemi-vertebra with different degrees of vertebra fusion. 7 cases were in C 3, 3 cases were in C 4 and 1 case was in C 5. Anterior-posterior combined approach was used. Firstly, discectomy and soft tissue release on concave side were made through anterior approach, then distraction on concave side and fusion with internal fixation were made through posterior approach and at last fixation and fusion in anterior approach were made. In this study we measured structure Cobb angle, compensatory Cobb angle, mandibular incline, shoulder balance and the angle difference of trapezius muscle preoperation and post operation. Perioperative neurological,vascular and wound related complicationswere recorded. Results:All patients' surgeries were completed successfully. Eight patients received single site distraction and 3 patients received distraction in two sites. The duration of surgery was 466±141 min (range 150-659 min), the estimated blood losswas 387±191 ml (range 100-660 ml) and follow up time was 12.2±9.5 months (range 3-24 months). Structural Cobb angle was 28.9°±13.1° pre-operation and 7.4°(3.0°, 27.7°) post-operation at 3 months, which was corrected significantly ( Z=-2.934, P=0.003). The correction rate was 58.1±26.1% (range 18.8%-97.6%). Structural Cobb angle was 13.2°±12.3°at 1 year post operation and had no significant difference compared with 3 months post operation ( t=1.960, P=0.107). Compensatory Cobb angle was 18.3°±6.1° pre-operation and 9.4°±7.3° post-operation at 3 months, which was corrected significantly ( t= 5.071, P<0.001) and the correction rate was 51.3%±28.3% (range 2.4%-94.7%). Compensatory Cobb angle was 8.9°±7.7° at 1 year follow up and was corrected significantly ( t=5.253, P=0.003) compared to 3 months after surgery and the correction rate was 61.4%±26.9%. Two patients developed C 5 nerve root dysfunction and 1 patient developed numbness on the index and middle fingers after surgery. All of them occurred on the concave side and recovered by conservative treatment. Conclusion:The application of distraction on the concave side in the treatment of congenitalcervical scoliosis is with good feasibility and clinical safety. Short-term follow-up showed excellent resultswith a promising future.
