ObjectiveTo determine the characters of symptomatic pancreatic pseudocyst due to acute pancreatitis and effects of surgical treatment with two kinds of procedure （internal drainage or external drainage）. MethodsOne hundred and fifteen cases hospitalized during recent ten years were retrospectively analyzed.ResultsWe found that necrotic tissue existed in the pseudocyst in most cases and infection might occur in these pseudocyst. Although effect of two kinds of surgery was similar, the clinical course was different. The complications after surgery were fewer in patients underwent internal drainage than that with procedure of external drainage, and average hospital day was 7d in cases with internal drainage and 11d in cases with external one respectively. Surgery of internal drainage used in treatment was not only successful in noninfectious and single pseudocyst, but in infectious or multiple seudocyst.ConclusionInternal drainage should be used in most cases and considered as the first selection in surgery of pseudocyst due to acute pancreatitis.
Objective To evaluate the therapeutic results of percutaneous injection of autogeous bone marrow for simple bone cyst and to analyze the prognostic factors of the treatment. Methods From March 2000 to June 2005, 31 patients with simple bone cysts were treated by percutaneous injection of autogeous bone marrow. Of 31 patients, there were 18 males and 13 females, aged 5 years and 7 months to 15 years. The locations were proximal humerus in 18 cases ,proximal femur in 7 cases and other sites in 6 cases. Two cases were treated with repeated injections. The operative process included percutaneous aspiration of fluid in the bone cysts and injection of autogenous bone marrow aspirated fromposterior superior iliac spine. The mean volume of marrow injected was 40 ml(30-70 ml).Results No complications were noted during treatment. Thirty patients were followed for an average of 2.2 years(1.5 years) with 2 cases out of follow-up. After one injection of bone marrow, 9 cysts(29.0%) were healed up completely, 7 cysts(226%)basically healed up,13 cysts (41.9%)healed up partially and 2 (6.5%) had no response.The satisfactory and effective rates were 67.7% and 93.5% respectively. There was significant difference between active stagegroup and resting stage group(P＜0.05). There were no statistically significant difference in therapeutic results between groups of different ages, lesion sites or bone marrow hyperplasia(Pgt;0.05). Conclusion Percutaneous injection of autogeous bone marrow is a safe and effective method to treat simple bone cyst, but repeated injections is necessary for some patients. The therapeutic results are better in cysts at resting stage than those at active stage.
【Abstract】Objective To evaluate the distribution of nerve growth factor receptor( P75 NGFR) in congenital choledochal cyst(CCC) and its clinical implication. Methods Specimens from 18 children with CCC and normal choledochal specimens from 9 controls were immuno-stained with P75 NGFR antibody. Results Extensive P75 NGFR staining was found in the nerve fibres of normal comnon bile duct，bly staining of ganglion cells were observed on the normal specimens. There was very little immunoreactive fibre in the CCC. Conclusion The abnormal distribution of P75 NGFR in the aganglionic choledochal suggests that abnormal P75 NGFR is related to the occurrance of the CCC.
OBJECTIVE: To evaluate the operative methods of biliary tract reconstruction after cystectomy of congenital choledochal cyst(CCC). METHODS: One hundred and six cases with CCC underwent cystectomy and biliary tract reconstruction in our hospital from July 1984 to December 1999 were followed up. Among them, there were three kinds of procedures in biliary tract reconstruction: with single Roux-Y hepaticojejunostomy in 48 cases, with intussusceptive valve to the line of Roux-Y hepaticojejunostomy in 37 cases, with rectangular valve to the line of Roux-Y hepaticojejunostomy in 21 cases. RESULTS: Fifty nine cases were followed up for 4.68 years in average. There were 3 cases with ascending cholangitis after single Roux-Y hepaticojejunostomy. And the symptom disappeared in 2 cases underwent reoperation with an intussueceptive valve plasty to the line of Roux-Y hepaticojejunostomy. No patients suffered from ascending cholangitis in the precautionary valve plasty group. CONCLUSION: It suggests that the postoperative ascending cholangitis can be prevented effectively if standard cystectomy and prophylactic intussusceptive valve added to the line of Roux-Y hepaticojejunostomy are carried out. The procedure should be performed as soon as possible providing the child is tolerable.
目的 探讨先天性胆总管囊肿(congenital choledochal cyst,CCC)术式选择与疗效的关系。方法 对1989年至1998年间38例CCC手术治疗病例进行回顾性研究。结果 38例中行胆肠Roux-Y吻合术20例，肝总管十二指肠高位大口吻合术18例。术后随机获随访31例。13例胆肠Roux-Y吻合术后随访3～7年，发现5例并发十二指肠溃疡，3例并发胆道逆行感染。18例肝总管十二指肠高位大口吻合术后随访2～5年，发现1例并发胆道逆行感染，无1例并发十二指肠溃疡。结论 由于肝总管十二指肠高位大口吻合术后远期并发十二指肠溃疡发生率较低，其与胆肠Roux-Y吻合术相比，是提高CCC患儿术后远期生活质量较理想的术式。
目的：探讨鼻前庭囊肿的最佳治疗方法。方法:在鼻内镜下辅以鼻窦电动切割器，对32例患者行鼻前庭囊肿揭盖术。结果:32例均获治愈，无1例并发症，随访1年以上，均未见囊肿复发和并发症。结论:鼻内镜下辅以鼻窦电动切割器行鼻前庭囊肿揭盖术，具有手术精确、时间短、创伤小、愈合快等微创手术优点，值得推广。
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。
