老年重症急性胰腺炎手术治疗探讨

目的：讨论老年重症急性胰腺炎的手术治疗。方法：我院1984年1月－2000年10月共收治60岁以上手术证实的重症急性胰腺炎26例，本对其手术治疗的方法和时机以及相应的并发症和死亡率进行回顾性分析。结果：本组术后死亡6例，其中4例死于MOF，2例死于ARDS。在发病24小时内手术8例中无1例死亡，24－36小时内手术14例有2例死亡，36小时后手术4例均死亡。结论：老年重症胰腺炎患多伴有心、肺、肾等重要器官慢性疾病，脏器代偿功能差，较易出现MOF，因此如有手术指证或经短期非手术治疗效果不明显，应及时手术，并在术中和术后采用合理的治疗措施，有利于减少术后并发症，降低手术死亡率。     

Groove pancreatitis associated with true pancreatic cyst

We report a case of groove pancreatitis (GP) associated with a true pancreatic cyst. An 81-year-old man who had suffered epigastric pain for 4 months was referred to Saisekai Kure Hospital. Computed tomography and endoscopic retrograde pancreatography showed a cystic lesion in the groove area of the pancreas. Serum amylase elevation and imaging findings suggested GP due to the cyst. Six weeks of medical treatment did not improve the clinical symptoms. Therefore, pancreatoduodenectomy was performed. Histologic examination revealed a true cyst with intraluminal necrosis, which produced a protein plug that obstructed the Santorini duct. The parenchyma surrounding the groove area showed marked fibrosis and inflammatory cell infiltration. GP due to true pancreatic cyst was diagnosed. Although GP is usually caused by overconsumption of alcohol, which leads to changes in the pancreatic juice and the ultimate blockage of pancreatic outflow, the histologic features in our patient suggest that true pancreatic cyst stands as a secondary cause of GP.     

乌司他汀对重症急性胰腺炎血浆内毒素水平的影响及其疗效观察

目的　观察乌司他汀治疗重症急性胰腺炎对血清内毒素水平的影响。方法　 4 0例重症急性胰腺炎患者随机分为乌司他汀治疗组和一般常规治疗组两组 ,两组患者住院后分别在第 1、4、7、10天抽血测定血清淀粉酶、血浆内毒素水平 ,结合APACHEⅡ评分系统分析观察乌司他汀的临床疗效。结果　重症急性胰腺炎入院后第 1天血浆内毒素水平明显高于正常健康对照组 ,分别为 (1.10± 0 .2 3)IU/L和 (0 .2 0± 0 .5 0 )IU/L(P <0 0 0 1) ,治疗组血清淀粉酶、血浆内毒素水平下降均较对照组明显 (P <0 0 1) ,住院第 7天APACHEⅡ评分值低于对照组 (P <0 0 5 )。结论　重症急性胰腺炎患者早期存在不同程度的内毒素血症 ,乌司他汀治疗重症急性胰腺炎疗效肯定 ,并能降低患者血浆内毒素水平和改善预后     

一种稳定的急性胰腺炎胰腺外多器官损伤大鼠模型

目的研究一种病理进程平稳的急性胰腺炎胰腺外多器官损伤动物模型.方法应用小剂量中等浓度胆盐、胰管内低压注射的方法,动态观察实验大鼠胰腺、肺、肝脏及肾脏的功能和病理改变.结果这种新的急性坏死性胰腺炎大鼠模型具有胰腺外持续、稳定的肝、肾损伤.结论这种急性坏死性胰腺炎大鼠模型适合于多器官功能损伤的病理机制及治疗学研究.     

ENDOSCOPIC PANCREATIC STENTING IN CHRONIC PANCREATITIS WITH DUCTAL DILATION PROXIMAL TO A STRICTURE: A SAFE and EFFECTIVE PROTOCOL

After removal of intraductal stones, a 10‐Fr or 7‐Fr pancreatic stent was placed in 16 patients with upstream ductal dilation proximal to a stricture of the main pancreatic duct. Stents were removed after a mean duration of 52.5 days. Nine patients underwent repeated stenting. About one year after removal of the initial stent, when the remaining upstream ductal dilation was found on follow‐up pancreatograms, the next stent was replaced. Repeated stenting improved outflow of pancreatic juice more effectively than one‐time stenting. Correlation between long‐term pain relief without recurrence of intraductal stones and reduction of duct diameter was also shown. Stent occlusion was observed in 14 of 30 stents. Stent occlusion was frequently associated with recurrence of pancreatitis and intraductal stones, and was also associated with morphologic changes in the pancreatic ductal system. Although there were no significant differences between stent patency of the initial stents and that of the next stents, stent patency of 10‐Fr stents was superior to that of 7‐Fr stents. 10‐Fr stents should be removed within 8 weeks and 7‐Fr stents should be removed within 4 weeks for the prevention of stent occlusion. Repeated stenting with short‐term stenting is therefore considered a safe and effective protocol of endoscopic pancreatic stenting.     

胰、胆疾病患者血清GLS含量测定

目的　研究胰、胆疾病患者血清GLS含量及其临床意义。方法　测定胰、胆癌症与非癌患者GLS含量 ,然后分组统计分析。结果　胰癌组GLS(973± 32 2mg/L)显著高于胰脏非癌组 (5 75± 2 18)和糖尿病组 (5 37± 87) ;胆道癌组GLS(90 8± 2 73)显著高于胆道非癌组 (5 2 1± 10 9)。该五组GLS阳性率 (>6 6 0mg/L)依次为 93.8%、2 6 .7%、4 .1%、85 .7%、9.3% ;胰、胆癌症组均显著高于非癌疾病组。结论　胰、胆癌症患者血清GLS显著增加 ;测定GLS对癌症诊断具有显著临床意义     

“胰岛素正常”的胰岛素瘤

目的分析胰岛素瘤胰岛素水平正常的原因，以提高其诊断水平。方法对我院1982年6月至2005年10月诊断为胰岛素瘤，且胰岛素水平检测结果在正常范围内的12例进行回顾性分析。结果12例患者均出现空腹或发作性低血糖症状，连续检测血糖，至少1次血糖值〈2．8mmol／L。同期检测外周静脉血中免疫反应性胰岛素（IRI）水平均〈25mU／L。周围静脉血中免疫反应性胰岛素／血糖比值（IGR）：〈0．3者5例，〉0．3者7例。12例中8例进行了血清C-肽检测，6例高于正常。结论少数胰岛素瘤患者的血胰岛素可在正常范围内，血胰岛素水平正常不能排除胰岛素瘤的诊断。     

急性胰腺炎恢复期并Wernicke脑病一例

患者男，34岁。大量饮酒后出现剑突下疼痛，伴恶心、发热，体温最高达38．5℃，发病3天入住当地医院治疗，诊断为“急性胰腺炎”。经禁食、胃肠减压、抑制胰酶分泌、抑酸、抗感染治疗，3天后疼痛明显减轻，血淀粉酶恢复正常、尿淀粉酶仍高于正常值。维持原治疗，治疗16天后，自觉上述症状消失后拔除胃管，但化验检查发现尿淀粉酶高（1294u／L），1天后再次留置胃管行胃肠减压，治疗33天后拔除胃管。出现头晕、恶心呕吐，呕吐物为胃内容物，予以“吗丁啉、思密达、多酶片”等药物对症治疗，效差。治疗38天后出现复视、视物不清、耳鸣，为进一步诊治，以“尿淀粉酶升高42天，呃逆1天，复视、乓鸣5天”为主诉入住我院。
