Detection of early organ dysfunction for the selection of treatment strategy on severe acute pancreatitis / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the severity related influencing factor and treatment strategy of severe acute pancreatitis with early organ dysfunction.</p><p><b>METHODS</b>From July 2007 to December 2008, 167 patients with severe acute pancreatitis were treated in the Surgical Department of Ruijin Hospital. The relationships between the happening of early organ dysfunction and outcome of the patients were observed, with operative or nonoperative treatment strategy.</p><p><b>RESULTS</b>Among 167 patients, 68 patients have early organ dysfunction, in which 39 with single organ dysfunction and 29 with multiple organ dysfunction. The early organ dysfunction were involved in 47.1% in cardiovascular system, 35.3% in lung and 29.4% in kidney. Aging (P < 0.05) and higher APACHE II score (P < 0.05) predicted a poor prognosis, which were benefit from early operation.</p><p><b>CONCLUSIONS</b>The mortality of the patients with SAP is related to age, and the degree of organ dysfunction as well. In the first phase of the disease, the selection of operation depends on the trends and the degree of early organ dysfunction before infected necrosis happens, with the aid of SOFA score as a scale.</p>

Long-term outcome and health-related quality of life in survivors of severe acute pancreatitis / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the health-related quality of life and postdischarge long-term outcome after severe acute pancreatitis.</p><p><b>METHODS</b>The hospital records of patients with SAP discharged healthy from January 2003 to December 2003 were reviewed. The Rand 36-item Health Survey with accessory question was mailed to each patient. The means and deviations for each of eight scales scores of SF-36 were calculated, the study population scores were compared with general Chinese population; Univariate analysis was applied to determining the effects of variables such as age, sex, causes of disease, mode of treatment, frequency of surgery, financial burden, length of stay, chronic complications. Accessory questions were analyzed separately.</p><p><b>RESULTS</b>The means and deviations for each of eight scales (PF, RP, RE, BP, VT, MH, SF, GH) scores of SF-36 in SAP patients were 83 +/- 15, 62 +/- 42, 69 +/- 36, 80 +/- 15, 69 +/- 19, 72 +/- 15, 75 +/- 18, 65 +/- 18, compared with general people. Except RP and SF, the others were similar. In the ANOVA of Physical Component Summary, the three variables mode of treatment, financial burden and length of stay were included (P < 0.05), while in that of Mental Component Summary, the two variables of gender and financial burden were included (P < 0.05).</p><p><b>CONCLUSIONS</b>The health-related quality of life in SAP patients is similar to that of general people. Greater attention should be given to mode of treatment, length of stay and financial burden to improve quality of life.</p>

The characteristic of severe acute pancreatitis and the selection of the therapeutic strategy / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the relationship between the clinical character and therapeutic strategy and prognosis in severe acute pancreatitis.</p><p><b>METHODS</b>From January 2001 to December 2005, 783 patients with SAP were treated. Therapeutic strategy was selected based on the preliminary scheme for diagnosis and treatment of severe acute pancreatitis by pancreatic surgery society of CMA. All the patients were divided into biliary group and non-biliary group, while 375 patients in biliary group, with 182 patients treated operatively and 193 patients treated nonoperatively; and 408 patients in non-biliary group, with 147 patients treated operatively and 261 patients treated nonoperatively.</p><p><b>RESULTS</b>There were 698 survivals, the overall survival rate was 89.1%. 357 survivals in the biliary SAP group, the survival rate was 95.0%, in which 171 survivals from operation treated cases, with the survival rate of 94.0%, and 186 survivals from non-operation treated cases, with the survival rate of 96.4%; 341 survivals in the non-biliary SAP group, the survival rate was 84.0%, in which 110 survivals from operation treated cases, with the survival rate of 74.8%, and 231 survivals from non-operation treated cases, with the survival rate of 88.5%. 48.3% patients of the survival group had organ dysfunction, and 18.3% patients had multiple organ dysfunctions, while 100% patients of the death group had organ dysfunction, and 97.6% patients had multiple organ dysfunction. Respiratory dysfunction was found to be the most common cause totally followed by nerve system dysfunction and shock, with the rates of 26.3%, 11.7% and 10.3%, respectively. Respiratory dysfunction, renal dysfunction and cardiac dysfunction are most commonly in death group, with the rate of 94.1%, 60.0% and 60.0%, respectively. The rate of fungi infection in the survival group and death group were 8.9% and 37.6%. The rates of alimentary tract fistula in the survival and death group were 0.9% and 14.1%, respectively.</p><p><b>CONCLUSIONS</b>The therapy aiming at the cause for biliary SAP and the operation aiming at infected pancreatic necrosis is helpful to improve curative rate; MODS is the main cause of death in severe acute pancreatitis. Respiratory dysfunction, renal dysfunction and cardiac dysfunction are high risk factors.</p>

Study on the position of genes responsible for gallstone disease in Chinese population / 中华外科杂志

<p><b>OBJECTIVE</b>To search the susceptibility genes of gallstone disease in Chinese population.</p><p><b>METHODS</b>A genome wide scan was performed in twelve families with gallstone disease using fluorescence-labeled microsatellite markers. Genehunter and Batchlink of Linkage package were used for non- parameter and parameter linkage analysis to search the linkage loci on chromosomes.</p><p><b>RESULTS</b>Four loci of D3S1266, D4S406, D9S1682 and D11S902 showed suggestive evidence for linkage. nonparametric linkage analysis (NPL)-score of D4S406 and D9S1682 was 1.77 (P = 0.05) and 1.92 (P = 0.04) respectively. The corresponding logarithm of the odds ratio (LOD)-score of D3S1266, D9S1682 were 1.35 and 2.07, and showed a rise of LOD-score from 1.35 to 2.71, 2.07 to 2.40 respectively when families with later-found patients or with higher triglyceride level were analyzed alone. Transmitted disequilibrium test of D11S902 showed a P-value of 0.0027.</p><p><b>CONCLUSIONS</b>Chromosome 3, 4, 9 and 11 may contain genes involved in gallstone disease in Chinese population, and chromosome 3, 9 may hide genes that are liked to gallstone disease in families with later-found patients or with higher triglyceride concentration.</p>

A survey on the diagnosis and treatment of biliary tract cancers in Shanghai / 中华外科杂志

<p><b>OBJECTIVE</b>To survey the status of diagnosis and treatment of biliary tract cancer in Shanghai.</p><p><b>METHODS</b>A clinical epidemiology investigation was carried out on 658 new cases of biliary duct cancers aged 35-74, that registered between June 1997 and May 2001 in urban Shanghai. Clinical findings were collected in 390 gallbladder cancer, 195 bile duct cancer and 73 ampullary cancer.</p><p><b>RESULTS</b>Biliary tract cancers mainly occurred in elderly patients. Ratio of males to female was 1:2.61 in gallbladder cancer, while bile duct cancer and ampullary cancer were slightly more common in men. Association with gallstones was 68.5%, 43.1% and 22.4% for gallbladder cancer, bile duct cancer and ampullary cancer, respectively. Diagnostic accuracy rate of B-ultrasonography was 63.1% in gallbladder cancer. Incidental gallbladder cancer accounted for 20%, while stage IVA and IVB patients reached up to 43.6%. Misdiagnosis rate was still high in bile duct cancer and ampullary cancer, it was 19.1% and 47.1% respectively. In addition, most patients presented jaundice at diagnosis. 69 cases (18.2%) of gallbladder cancer, 50 cases (25.6%) of bile duct cancer and 54 cases (74%) of ampullary cancer underwent radical resection, the 1-, 3- and 5-year survival rates were 58.5%, 42.8% and 40.7%, 58%, 28.3% and 11.1%, 81.5%, 39.2% and 26.9%, respectively. 79 patients with bile duct cancer underwent palliative drainage, and most cases died within 1 year. Metal endo-prostheses or plastic stents were placed into the biliary tract in 38 patients. The median survival was about 7 months.</p><p><b>CONCLUSIONS</b>It is difficult to make early diagnosis of biliary tract cancers. Standardization of the operation for gallbladder cancer must be respected. Surgical exploration should be undertaken when a bile duct cancer is suspected and there are no contraindications to surgery. Pancreatoduodenectomy should be recommended for ampullary cancer.</p>

Study on the characteristics of inheritance and epidemiology in one pedigree with gallstone disease / 中华流行病学杂志

<p><b>OBJECTIVE</b>To study the characteristics of inheritance and epidemiology of gallstone disease in one pedigree.</p><p><b>METHODS</b>A gallbladder disease-specific questionnaire was administered to all family members to ascertain histories of cholecystectomy and other medical conditions as well as anthropometrical data. Laboratory examination and ultrasonography were performed to determine the existence of gallstone.</p><p><b>RESULTS</b>One hundred and thirteen members of four generations in the index family were enrolled in the study. The prevalence of gallstone in females (34.48%) was higher than in males (23.64%) but with no significant difference. The prevalence in the second and third generations (52%) was higher than in others (20%) (P < 0.05). The heritability and standard error showed as 86.38% +/- 46.46% in I generations. Body mass index, histories of hypertension, hyperlipidemia and blood glucose were positively related to gallstone disease (P = 0.012, < 0.01, 0.017, 0.043, respectively) in this family. Gallstone disease was not significantly related to history of diabetes, daily alcohol or diet habit. Plasma cholesterol and triglyceride levels were not correlated with gallstone disease.</p><p><b>CONCLUSION</b>Gallstone disease presented aggregation in the family and was in accordance with the characteristics of autosomal dominant inheritance. Being female, obesity, hypertension and history of hyperlipidemia might serve as risk factors to this family.</p>

Expression of liver receptor homolog 1 gene in patients with cholesterol gallstone disease / 中华消化杂志

Objective To investigate the mRNA expression of liver receptor homolog 1 (LRH-1) gene in patients with cholesterol gallstone disease so that to elucidate the biomolecular pathogenesis of gallstone for- mation.Methods Twenty-seven patients with cholesterol gallstone (CGS) and 14 controls were included in this study.Biliary composition was assayed and mRNA expression of hepatic LRH 1 gene was determined by real time polymorphism chain reaction.Results In CGS patients,expression of LRH-1 was significantly higher than that in controls (14.18?9.37 vs 7.86?6.19,P＜0.05),and cholesterol of bile was oversaturated (1.17?0.27).Conclusion The formation of CGS may be related to increased expression of hepatic LRH-1 gene.
