目的总结暴发性胰腺炎（FAP）的临床特点及诊治经验。方法对2008年5月至2010年7月期间我院收治的18例FAP患者的临床特点及治疗进行回顾性分析。结果18例患者中，2例胆源性FAP患者急诊行胆总管切开减压加T管引流术，术后痊愈1例，死亡1例； 5例发生腹腔间隔室综合征者选择急诊手术行胰腺被膜切开减压加引流术，治愈3例，死亡2例； 其余11例患者通过呼吸支持、腹腔灌洗等治疗，其中1例高龄患者既往有冠心病因心功能衰竭而死亡，5例胰腺坏死感染，采取胰腺周围坏死组织清除加引流手术，并根据细菌及真菌培养结果联合使用抗细菌及真菌药物治疗，3例治愈，2例感染未能控制引发多器官功能障碍综合征而死亡。本组共死亡6例。结论FAP的治疗与一般的重症急性胰腺炎相比，有其专有的特点，更注重整体一体化治疗，要求外科医生和ICU医生协同，保护好患者的脏器功能，在全程监护的条件下给予呼吸循环支持，同时第一时间针对患者的病情采取血液滤过、腹腔灌洗、微创手术等治疗。
ObjectiveTo investigate the value of endoscopic sphincterotomy (EST) on treating sphincter of Oddi dysfunction (SOD). MethodsForty-two patients with SOD according to Rome Ⅱ diagnostic criteria were retrospectively summarized. Bile duct residual stone, tumor or biliopancreatic duct obstruction diseases were excluded by B ultrasound, CT, and MRCP examination. Total 42 patients underwent EST. ResultsEST was done successfully in 42 cases, success rate was 100%. Postoperative acute pancreatitis occurred in 5 patients (11.90%), which were cured by 3－7 d conservative treatment. There were no complications of severe acute pancreatitis, digestive tract perforation, hemorrhage, and cholangitis. Follow-up 12-45 months (mean 23.8 months), symptoms of abdominal pain in all cases were improved or relieved, the effective rate was 100%. There were 2 cases treated conservatively because of hyperlipemic pancreatitis. ConclusionEST has become the primary treatment procedure for SOD because of definite outcome, less suffering, safety, less complications, and reproducibility, which are concordant with the requirements of minimally invasive surgery.
ObjectiveTo investigate the synergistic antitumor effects of ionizing radiation and the cytosine deaminase (CD)/5-flurocytosine (5-FC) system therapy in human pancreatic cancer cell.MethodsThe expression vector containing CD was transfected into the human pancreatic cancer cell line PC3. The clones were picked out after G418 selection. The CD gene integration and expression were confirmed by the RT-PCR. The cytotoxicity to the cells with or without CD and (or) ionizing radiation under the treatment with 5-FC was measured by the MTT assay. The clonogenic assay was used to investigate the radiosensitizing effect of 5-FC on the PC3 cells transfected or untransfected with CD gene.ResultsThe CD gene was stably expressed in the PC3 cells transfected with CD gene. The cytotoxic effect of 5-FC was superior on the PC3 cells transfected than that of untransfected with CD gene (P<0.05) and which were enhanced in combination with the ionizing radiation (P<0.05). The CD/5-FC enhanced the radiosensitivity of PC3 cells transfected with CD gene (P<0.05). The change in the radiosensitivity was quantified by calculating the sensitization enhancement ratio (SER) at the clinically relevant dose of 2 Gy. The SER was 1.5 in the PC3 cells transfected with CD gene by giving ionizing radiation of 2 Gy.ConclusionsCD/5-FC system is a potenial radiosensitizer in PC3 cells transfected with CD gene. Ionizing radiation and CD/5-FC system is more effective for killing effect of PC3 cells than ionizing radiation or CD/5-FC system alone.
目的 探讨5例特重型胰腺炎的特点及治疗方法。方法 我院2001年8月至2003年8月共收治特重型胰腺炎患者5例。其中入院后18 h内心跳、呼吸骤停3次的重症急性胰腺炎（SAP）1例，治疗以及时血液滤过和心、肺、脑复苏为重点； SAP并发胰性脑病2例，以大剂量维生素B1的补充，或足量补给浓缩红细胞为治疗重点； 并发多个器官功能障碍的暴发性胰腺炎（FAP）2例，治疗重点是血液滤过和防治多器官功能衰竭的级联放大反应，其中1例以高渗性糖昏迷为主要表现，治疗重点是内稳态的纠正，血液滤过，重要器官功能维护。结果 5例特重型胰腺炎患者均治愈，平均住院时间为32.2 d。结论 器官功能的复苏和维护、外科ICU监护、短时血液滤过、内稳态的纠正、中西药综合治疗及病因、对症的个体化治疗是特重型胰腺炎的重要治疗措施。
【Abstract】ObjectiveTo study the therapeutic effects of indwelling catheters in patients with severe acute pancreatitis (SAP). MethodsThe clinical data of 113 patients with severe acute pancreatitis admitted to our hospital from Aug. 2002 to May 2004 were collected. The patients were divided into the indwelling catheter group (45 cases) and the control group (68 cases).The APACHEⅡscores and therapeutic results were compared. The drainage and intraabdominal pressure (IPA) were monitored. Results The APACHEⅡscores on day 2 and day 5 after therapy in indwelling catheter group were significantly decreased compared with the control group(P=0.000).The average hospital stay and cyst morbidity of the indwelling catheter group were significantly decreased compared with those of the control group(P=0.000). The mortality rate was lower in the indwelling catheter group, but there was no statistical difference between these two groups(Pgt;0.05). The IAP was positively correlative with the drainage volume, hospital day and APACHEⅡscores(r=0.552, r=0.748, r=0.923，P=0.000). ConclusionThe indwelling catheter is an important treatment in patients with SAP.
Objective To discuss the value of biliary stent in treatment of malignant biliary obstruction with different pathways of bile duct stent insertion. Methods Fourty-two cases of malignant biliary obstruction whose biliary stent insertions were through operation (n=18), PTCD (n=17) and ERCP (n=7) respectively were reviewed retrospectively. Results The bile duct stents were successfully inserted in all patients through the malignant obstruction and achieved internal biliary drainage. Compared with the level of the bilirubin before operation, it decreased about 100 μmol/L one week after the stent insertion in all patients. Compared with the levels of glutamic oxalacetic transaminase, glutamic pyruvic transaminase, alkaline phosphatase and glutamyltranspeptidase before operation, they decreased 1 week after the stent insertion （Plt;0.05). The median survival time was 22 weeks. The average survival time was (32.89±33.87) weeks. Two patients died in hospital after PTCD, and the mortality was 4.76%. Complications included 8 cases of cholangitis, 3 cases of bile duct hemorrhage and 2 cases of hepatic failure. Conclusion The bile duct stent insertions through operation, PTCD and ERCP are all effective in relieving the bile duct construction with malignant biliary obstruction. Each method should be chosed according to the systemic and local condition for every patient so as to improve the safety and efficiency, and to decrease the occurrence of complications.
