OBJECTIVETo investigate the severity related influencing factor and treatment strategy of severe acute pancreatitis with early organ dysfunction.

METHODSFrom 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.

RESULTSAmong 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.

CONCLUSIONSThe 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.

OBJECTIVETo investigate the relationship between the clinical character and therapeutic strategy and prognosis in severe acute pancreatitis.

METHODSFrom 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.

RESULTSThere 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.

CONCLUSIONSThe 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.

OBJECTIVETo evaluate the health-related quality of life and postdischarge long-term outcome after severe acute pancreatitis.

METHODSThe 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.

RESULTSThe 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).

CONCLUSIONSThe 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.
