Objective To investigate the long-term clinical results of treatment of adult unicameral bone cyst with cancellous allograft. Methods From 1993 to 1998, 15 patients with unicameral bone cyst were treated by allograft with lyophilized cancellous bone. Among 15 patients, there were 5 males and 10 females, aging 19-41 years with an average of 27 years. The average follow-up time was 7.5 years (6-11 years). The X-ray films were taken and the CT scanning were carried out. Results The X-ray films showed that the allograft particles became vague 2-3 months after operation, that the allograft particles fused and began to form new bone and the bone density increased 5 months after operation, and that new bone formation completed after 7 months of operation. At the end of follow-up, remodelling in new bone occurred. Reoccurrence was not found in all patients. The symptom of pain disappeared or relieved obviously. Conclusion Allograft of lyophilized cancellous bone is an effective treatment for adult unicameral bone cysts.
Objective To study the expression of p16 and Rb gene in primary gallbladder carcinoma (PGC). MethodsFiftysix cases of PGC and 26 of gallbladder benign lesions were observed by immunohistochemistry (SP). ResultsThe positive rates of p16 and Rb protein in PGC were 46.3% and 71.4% respectively. No association of Rb expression with histological grade, histological type, invasion, metastasis and prognosis was found. There were close correlation between p16 expression and invasion, metastasis as well as prognosis. The inverse correlation of p16 and Rb gene expression in PGC was confirmed. Conclusion The loss of p16 or Rb gene protein is an important molecular event in PGC,and closely related to the block in the negative regulatory pathway of all cell cycle. The detection of p16 protein may be useful in evaluating biological characteristics and prognosis in PGC.
目的:分析经后腹腔镜肾上腺囊肿去顶减压术的疗效,安全性和临床价值。方法:我院2004年12月至2007年12月6例经后腹腔镜肾上腺囊肿去顶减压临床资料进行回顾分析。结果:经后腹腔镜5例肾上腺囊肿患者顺利切除去顶,其中左侧肾上腺囊肿3例,右侧肾上腺囊肿3例。1例转开放,为双侧肾上腺囊肿。平均手术时间(45.73±1.32)min,平均术中出血量(7.35±0.45)mL。平均住院天数(7.67±0.24)天,平均术后住院天数(5.0±0.11)天。结论:经后腹腔镜肾上腺囊肿去顶减压是一种安全,有效且可行的治疗方式,必要时应及时转开放。
目的 总结Lilly氏法切除先天性胆总管囊肿的经验。方法 对1980年以来我院收治的20例采用Lilly氏法保留胆总管囊肿后壁外层切除先天性胆总管囊肿的技术要点及手术疗效进行了回顾性分析。结果 该术式操作方便，术后随访表明，它可有效地解除胆管囊肿的主要症状，无严重手术并发症及不良后果。结论 该术式安全简便，疗效满意，在Ⅰ型先天性胆总管囊肿炎性粘连较重时可适当选用。
Objective To investigate the diagnosis and treatment of congenital choledochal cysts(CCC) in children. MethodsThe manifestation, auxiliary examination, mode of operation and effect of 42 patients with CCC in children from Jan., 1980 to June, 1999 were analyzed retrospectively.Results The patients with the triad of jaundice, an abdominal mass, and pain was 38.1% among the 42 patients. B-ultrasonic diagnosis was made with a correct diagnostic rate of 95.2%. The effective rate of internal drainage was significantly lower than that of resection of the cyst(χ2=19.36, P＜0.001) while the reoperation rate and incidence of carcinoma of internal drainage were higher than those of resection of the cyst(χ2=11.59, P＜0.001 and χ2=4.97, P＜0.05). Conclusion B-ultrasonic diagnosis is recommended as the first examination method. Internal drainage should be abandoned. Resection of the cyst with Roux-Y hepaticojejunostomy is recommended as the treatment of choice on extrahepatic cholangiectasis. Liver transplantation is a reasonable choice to treat the diffuse intrahepatic cholangiectasis.
目的探讨非功能性甲状旁腺囊肿的临床特点，总结其诊治经验。 方法回顾性分析6例非功能性甲状旁腺囊肿临床资料，结合该病的临床症状、辅助检查、随诊情况，讨论其诊断、治疗与预后。 结果6例患者均行手术治疗，术后病理确诊为非功能性甲状旁腺囊肿，术后均获得随访，随访时间6个月～5年，平均42个月，无复发。 结论非功能性甲状旁腺囊肿术前诊断困难，确诊依靠病理检查，手术切除为主要治疗手段。
Choledochal cysts are characterized by single or multiple cystic dilatations of the intrahepatic and / or extrahepatic biliary ducts. The typical presentation of this condition is non-specific. Clinicians must have a high clinical suspicion of choledochal cysts while investigating patients with jaundice, abdominal pain, and abdominal mass. There are multiple classifications for choledochal cysts . The Todani classification system is the most widely used in clinical practice. Based on clinical practice and thinking, we established a new “three regions and five types” classification system on the basis of Todani classification to guide clinical work, but further verification is needed. Surgery is the mainstay of treatment for choledochal cysts and the approach depends on the cyst type and the extent of hepatobiliary pathology. The principles of treatment include complete excision of the cyst and restoration of biliary-intestinal continuity. In view of the risk of biliary malignancy continues to be high after surgery, long-term follow-up is strongly recommended.
