OBJECTIVE: To provide experimental basis for improving the curative effect of pectus excavatum. METHODS: Twelve rabbits were adopted in this experiment. After the bilateral second and third costal cartilages of the rabbits were resected subperichondrially, their right second and third costal perichondriums were damaged intentionally. Then, the bilateral third costal perichondriums were stitched into a tube-like structure and the second ones were left opened. After 2, 4, 6 of operation, the bilateral second and third neocartilages were measured for their width, and histological character were observed under microscope. RESULTS: 1. After 2, 4, 6 months of operation, the average width of the bilateral second neocartilages were significantly greater than the preoperative ones. 2. 4 and 6 months after operations, there was no significant difference in the average width of the bilateral third neocartilages and the preoperative ones. 3. The amount, distribution of costal neocartilage cells and the arrangement of costal neocartilage matrix within the left second and third costal cartilages were better than the right under the light microscope. 4. The left third costal neocartilage was regenerated and remodeled better than all the others. CONCLUSION: The integrality of costal perichondrium is in favor of the regeneration of costal cartilage, and the sleeve stitch of costal perichondrium facilitates the remodeling of costal neocartilage.
ectus exeavatum is the most common chest wall deformity. The impairment of cardiopulmonaryfunction, severe psychological injury and other complications will be caused by the deformity. ″TheSternal Turnover″and″ The Sternal Elevation″are respective difference in indications andcharacteristics to treatment of pectus exeavatum. Pectus excavatum deformity will be repaired with theproper procedure and postoperative treatment. Their exercise tolerance and cardiac function will alsobe impro...
【摘要】目的探讨急危重胆总管囊肿的治疗。方法对我院1984~2001年收治的41例急危重胆总管囊肿患者的临床资料进行回顾性分析。结果41例患者均行囊肿切除、胆道重建术，其中3例患者分两期完成，全部病例均获治愈，随访9例近、远期效果均较好。结论囊肿切除、胆道重建术已成为根治胆总管囊肿的首选术式，但必须做好高危因素的处理，以提高手术安全性及疗效，只要度过围手术期，其预后较好。
Omphalocele is a less common congenitalmalformation in neonates and belongs to the realm of emergent surgical treatment. Early repair is of crucial importance for saving the patient s life. Ten neonates with omphalocele have undergone early surgical repair since 1988. The overall result was satisfactory. There were 8boys and 2 girls. The time of operation ranged from one to fortyeight hours after birth (24 hours in 8 cases). All of them were term neonates, except in onecase being premature. None of them had rupture of the sac membrane. The minor and major omphalocele were in 8 and 2 cases, respectively. Five cases accompaniedwith other congenital malformations (1 to 3 kinds). One case of them was complicated by exompholos-macroglossia-gigantism (EMG syndrome). Nine cases were treated by primary stage of surgical repair. One case with major omphalocelehad undergone two-staged operation. Nine neonates were survived and only onedied of pneumonia and scleroderma postoperatively. The patients were followed up for 3 months to 5 years, 9 cases were satisfactory. Early surgical repairwas essential to successful treatment. The choice of surgical methods, the management of concomittant malformation in the alimentary tract and the factors influencing the prognosis were discussed.
OBJECTIVE To inquire the indications, contraindications, and operative methods of the treatment of spastic cerebral palsy with selective posterior rhizotomy (SPR), and to improve the therapeutic results and decrease the incidence rate of complications. METHODS The documents about SPR were extensively consulted, and the mechanisms, indications, contraindications, operative methods, muscular tension changes and complications after operation were reviewed. RESULTS With the methods of SPR, I alpha fibers of afferent nerve were selectively amputated, reflex circle of spinal cord was locked, and the muscular tension was decreased, so myospasm was removed. The results after operation and incidence rate of complications were closely related to the indications. The therapeutic results were better when the percent of spinal nerve rhizotomy was less than 50%. CONCLUSION It is a good method for the treatment of spastic cerebral palsy.
