Chest wall surgery used to be a subspecialty of traditional thoracic surgery, which has an ancient history of research and clinical practice. It has gradually become an independent professional field in recent years. With the change of concept and the progress of interdisciplines, we have deepened our understanding of related diseases, and the treatment of chest wall surgical diseases has also acquired new characteristics. This article reviews the progress in the treatment of chest wall surgical diseases including chest wall trauma, chest wall deformity, chest wall tumor, chest wall infection and chest wall defect from the perspective of chest wall surgery.
Objective To evaluate the effect of mechanical suture in surgery of esophageal carcinoma,Methods Five hundred and sixty-eight cases of esophagogastrostomy and esophagojejunostomy for esophageal and cardiac carcinoma were collected in our hospital between January, 1988 and December, 2002. They were devided into two groups according to the methods of anastomoses, the group by stapler and the group with hand. The incidence of postoperative complications in the two groups was compared. Results The time of esophagogastrostomy, the total operating time, and postoperative fasting time of group by stapler were shorter than those of group with hand （Plt;0. 01）, and there was no statistically difference in the median hospitalized time after operation for two groups. The anastomotic leakage, anastomotic stricture, anastomotic bleeding , incidence of postoperative complications in respiration and circulation and mortality rate of group by stapler were lowed than those of group with hand （2.1%, 1.4%,0%,2.8% and 0.7% vs.6.8%,4.3%,1.4%,16.5% and 2.9%）. There was no statistical difference in the postoperative gastro-esophageal reflux for two groups （P 〉 0.05 ）. Conclusion The median time of esophagogastrostomy and the median operating time by stapler are decreased and the incidence of postoperative complications is decreased.
Objective To introduce a new approach of neurotization to treatment of the shoulder syndrome after the radical neck dissection by using transpositional anastomosis of C7 posterior root and the spinal accessory nerve to reconstruct the function of trapezius muscle. Methods From March 1999 to February 2001, 10 patients underwent the neurotization during the radical neck dissection. In the operation, the apo-cranial part of spinal accessory nerve was preserved from the trapezius muscle (gt;3.0 cm in length) and anastomosed to C7 posterior root. Objective physical examinations and electromyography were conducted before and after operation.One, 6 and 12 months after operation the trapezius muscle function after the transpositional anastomosis was evaluated. Results One, 6 and 12 months after operation, the recovery rates of each part were as follows: 9.8%, 68.9% and 73.5% in upper part; 4.7%, 73.6% and 69.4% in middle part; and 6.2%, 70.5% and 70.3% in lower part. The range of abduction motion of upper arm in 7 cases (70%) exceeded 90°. The mean maximal abduction angle was more than 95°. Evaluation of the shoulder function showed that myoatrophy was mild and the disability of abduction was classified as grade Ⅱ in 7 cases and grade Ⅲ in 3 cases. Conclusion Transpositional anastomosis of the C7 posterior root to thespinal accessory nerve after radical neck dissection can well reconstruct the function of trapezius muscle. This approach provides a wide indication in comparison with the functional neck dissection without impairment of arm function afterthe cutting of C7.
Objective To review the application and research progress of subtalar distraction bone block arth-rodesis in the treatment of calcaneus fracture malunion. Methods The recent literature concerning the history, surgical technique, postoperative complication, indications, and curative effect of subtalar distraction arthrodesis with bone graft block interposition in the treatment of calcaneus fracture malunion was summarized and analyzed. Results Subtalar distraction bone block arthrodesis is one of the main ways to treat calcaneus fracture malunion, including a combined surgery with subtalar arthrodesis and realignment surgery for hindfoot deformity using bone block graft. The advantage is on the base of subtalar joint fusion, through one-time retracting subtalar joint, the posterior articular surface of subtalar joint implants bone block can partially restore calcaneal height, thus improving the function of the foot. Compared with other calcaneal malunion treatments, subtalar distraction arthrodesis is effective to correct complications caused by calcaneus fracture malunion, and it can restore the height of talus and calcaneus, correct loss of talocalcaneal angle, and ease pain. Conclusion Subtalar distraction bone block arthrodesis has made remarkable progress in the treatment of calcaneus fracture malunion, but it has the disadvantages of postoperative nonunion and absorption of bone block, so further study is needed.
ObjectiveTo discuss the evaluation of clinical grading for neonates with hypoxic-ischemic encephalopathy (HIE) by diffusion weighted imaging (DWI). MethodsWe retrospectively analyzed the DWI findings of 39 neonates with HIE diagnosed by clinical criteria from December 2009 to July 2013. Abnormal signals were observed for 23 neonates (59%). These neonates were divided into three groups (group A, B and C) according to the shape and range of abnormal signals. Then Kappa test was performed between groups of different clinical grading (light, medium, severe). ResultsFor groups arranged based on abnormal signals and clinical grading, the Kappa value of the consistency test was 0.797 (P < 0.001). ConclusionsDWI negativity cannot exclude the existence of HIE. However, when abnormal signals occur, we can infer the severity in neonates with HIE according to the shape and range of abnormal signals by DWI.
目的探讨急诊肝动脉栓塞（TAE）治疗原发性肝癌破裂出血的临床效果和意义。方法收集我院近10年来收治的38例原发性肝癌破裂出血的资料，按治疗方法不同分为保守治疗组、急诊手术组及急诊TAE治疗组，比较3组间的输血量、术后肝功恢复率、住院时间及死亡率。结果急诊TAE治疗组与保守治疗组及急诊手术组比较，输血量少，术后肝功恢复率高，住院时间短和死亡率低，差异有统计学意义（Plt;0.05,Plt;0.01）。结论对于失去根治切除机会或不能耐受手术的原发性肝癌破裂出血的患者，可首选急诊TAE方法，并且还可为一部分患者将来行二次根治切除手术创造机会。
