RESUMO
OBJECTIVE: To investigate the severity related influencing factor and treatment strategy of severe acute pancreatitis with early organ dysfunction. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

OBJECTIVE: To investigate the strategy of controlling fluid resuscitation for severe acute pancreatitis (SAP) in acute phase. METHODS: From March 2001 to January 2006, 83 patients meeting for experimental criteria were included in this clinical trial. They were divided into early fluid expansion group (Group I, within 24 h after admission, 21 patients), middle fluid expansion group (Group II, within 25 - 48 h, 35 patients) and late fluid expansion group (Group III, within 49 - 72 h, 27 patients). Parameters of treatment of fluid therapy within 4 d after admission were observed. Serum lactic level was measured on admission and on meeting for criteria of fluid expansion. APACHEII scores, operation rate within 2 weeks, rate of mechanical ventilation, rate of ACS and survival rate were observed. RESULTS: Time interval for meeting fluid expansion criteria in Group I, Group II, Group III was (13 +/- 6) h, (38 +/- 5) h and (61 +/- 8) h, respectively. And there was statistical significance among them (P < 0.05). HCT (%) in Group I (33 +/- 6)% was lower than that of Group II (40 +/- 6)% and Group III (42 +/- 11)% significantly (P < 0.01) at the first day after admission; and there was no statistical significance between Group II and Group III. The amount of crystal and colloid infused in Group I (4014 +/- 2887) ml and (1220 +/- 705) ml at the day of admission was more than those of Group II (2366 +/- 1959) ml and (821 +/- 600) ml and Group III (2615 +/- 1574) ml and (701 +/- 585) ml (P < 0.01); but there was not different between Group II and Group III (P > 0.05). The ratio of colloid and crystal in Group III at the day of admission was lower than those of Group I and Group II (P < 0.05). The total amount of fluid infused was not different among 3 groups for the 4 d (P > 0.05). And infusion rate at the day of admission in Group I was more rapid than those of Group II and Group III (P < 0.05); and there was no difference between Group II and Group III (P > 0.05). The total amount of fluid sequestration in Group II for the 4 d was lower than those of Group I and Group III (P < 0.05); and there was no statistical significance between Group I and Group III (P > 0.05). At the first to the third day after admission APACHEII scores in Group I were higher than those of Group II and Group III (P < 0.05); and at the second and third day, APACHEII scores in Group III were higher than those of Group II (P < 0.05). Rate of mechanical ventilation in Group I (85.7%) was higher than those of Group II (37.1%) and group III (63.0%) (P < 0.05); and rate of ACS was most lowest in Group II (37.1%) (P < 0.05). Survival rate in Group I (38.1%) was lower than those of Group II (85.7%) and Group III (66.7%) (P < 0.05); and Group III was lower than that of Group II (P = 0.075). CONCLUSIONS: Within 72 h after onset of the disease, survival rate is improved significantly through controlling fluid resuscitation and prevention of body fluid sequestration.

OBJECTIVE: To evaluate the health-related quality of life and postdischarge long-term outcome after severe acute pancreatitis. METHODS: 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. RESULTS: 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). CONCLUSIONS: 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.

OBJECTIVE: To investigate the relationship between the clinical character and therapeutic strategy and prognosis in severe acute pancreatitis. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

OBJECTIVE: To investigate therapeutic strategy of fulminant acute pancreatitis (FAP) in acute response stage. METHODS: Sixty-four patients were divided into Death group (27 patients) and Survival group (37 patients). The time course of shock and recovery of enteral function, parameters of fluid resuscitation, PaO(2)/FiO(2) and AaDO(2) at 24 hours prior to mechanical ventilation, rate of continuous venovenous hemofiltration (CVVH) and abdominal compartment syndrome (ACS), severity of the disease in the acute response stage were investigated. And the effect of surgical manner and time on the prognosis was also analyzed. RESULTS: Compared with Survival group, the time course of shock and recovery of enteral function in Death group were prolonged significantly (P < 0.05). Between the groups, there was no difference in the amount of crystal fluid infused from admission to 72 hours after, but the amount of colloid fluid infused and ratio of amount of colloid and crystal fluid in Survival group were higher (P < 0.05). The amount of fluid retention in third space from admission to 72 hours after in Death group was higher than that of Survival group significantly (P < 0.05). The fluid infusing rate in Survival group in the first day of admission was faster than Death group (P < 0.05). PaO(2)/FiO(2) and AaDO(2) in 24 hours prior to mechanical ventilation in Death group were negatively changed significantly. Within 72 hours after the onset of the disease, the rate of CVVH in Survival group was higher than Death group. Incidence rate of ACS and the APACHEII scores within 72 hours after admission in Death group were higher than in Survival group. The cure rate of the patients operated in the day 7 to day 14 after admission was higher than that of patients operated prior and post this period. Time for the first operation in operated patients was earlier than patients received minimally invasive drainage (MID) and its cure rate was lower than that of MID Group. CONCLUSIONS: It is the key point to shorten the time course of ischemia, to control persistent systemic inflammatory response syndrome (SIRS) and to adopt reasonable surgical intervention in acute response stage for FAP.

BACKGROUND: Since being reclassified by WHO in 1996, solid pseudopapillary tumour (SPT) of pancreas has been recognized as the internationally accepted name. Clinicians are lacking in knowledge of this rare disease so the misdiagnosis and inappropriate therapy are hard to avoid. The clinic data on 22 patients were summarized to study the misdiagnosis and treatment of a sample of SPTs. METHODS: Twenty-two female patients with SPT were studied retrospectively and divided into two groups, the misdiagnosed group and the correctly diagnosed one. The analyses were performed with Fisher test with accurate probability for categorical data, and Kruskal-Wallis test for ranked data. RESULTS: The rate of misdiagnosis in this sample was 45.5%. The misdiagnosed SPTs were apt to be the incomplete capsule ones (P = 0.020), which resulted in obvious difficulties during operation (P = 0.024). In the misdiagnosed SPT group, the medical expenses increased significantly (P = 0.042), and the number of days in hospital greater than in correctly diagnosed group (P = 0.041). CONCLUSIONS: Although SPT has low malignancy with excellent prognosis after surgical treatment in most patients, the misdiagnosis of SPT increases the social and economic burdens on patients. It is important to analyse the causes of misdiagnosis.

With the advances in immunology and molecular biology, new recognition in the pathogenesis, progression, and metastasis of carcinoma have been achieved. Studies on gene therapy for pancreatic carcinoma have been attempted in different ways, such as inhibiting oncogene, activating tumor suppressor gene, inducing apoptosis, applying gene directed enzyme prodrug therapy, and immune activation. New specific target genes and further development of gene technology may bring the break-through in this field.

OBJECTIVE: The surgical therapies and prognoses on 21 solid-pseudopapillary tumors (SPT) of pancreas were summarized in our center. METHODS: Twenty-one SPTs were retrospectively studied and divided into two groups, the complete capsular group and the incomplete one. The analyses were performed by SAS6.12 Stat. software. RESULTS: There are no tumor recurrences in all patients. There are significant difference between operative types in radical resection and the tumor position of the pancreas (P = 0.038). There are also significant differences between the capsular integrity and the course of the diseases (P = 0.029), and the possible malignant cells by the frozen section examination (P = 0.001), and the size of the tumor (P = 0.0004). The judgement on the capsular integrity of the tumor could directly effect the adoptable operative types (P = 0.001). CONCLUSIONS: The surgical resection is good treatment for the SPT, which has satisfying prognosis.

AIM: To evaluate the therapeutic effect of adenoviral-vector-delivered human interleukin-10 (hIL-10) gene on severe acute pancreatitis (SAP) rats. METHODS: Healthy Sprague-Dawley (SD) rats were intraperitoneally injected with adenoviral IL-10 gene (AdvhIL-10), empty vector (Adv0) or PBS solution. Blood, liver, pancreas and lung were harvested on the second day to examine hIL-10 level by ELISA and serum amylase by enzymatic assay. A SAP model was induced by retrograde injection of sodium taurocholate through pancreatic duct. SAP rats were then administered with AdvhIL-10, Adv0 and PBS solution by a single intraperitoneal injection 20 min after SAP induction. In addition to serum amylase assay, levels of hIL-10 and tumor necrosis factor-alpha (TNF-alpha) were detected by RT-PCR, ELISA and histological study. The mortality rate was studied and analyzed by Kaplan-Meier and log rank analysis. RESULTS: The levels of hIL-10 in the pancreas, liver and lung of healthy rats increased significantly after AdvhIL-10 injection (1.42 ng/g in liver, 0.91 ng/g in pancreas); while there was no significant change of hIL-10 in the other two control groups. The concentration of hIL-10 was increased significantly in the SAP rats after AdvhIL-10 injection (1.68 ng/g in liver, 1.12 ng/g in pancreas) compared to the other two SAP groups with blank vector or PBS treatment (P<0.05). The serum amylase levels remained normal in the AdvhIL-10 transfected healthy rats. However, the serum amylase level was significantly elevated in the other two control SAP rats. In contrast, serum amylase was down-regulated in the AdvhIL-10 treated SAP groups. The TNF-alpha expression in the AdvhIL-10 treated SAP rats was significantly lower compared to the other two control SAP groups. The pathohistological changes in the AdvhIL-10 treated group were better than those in the other two control groups. Furthermore, the mortality of the AdvhIL-10 treated group was significantly reduced compared to the other two control groups (P<0.05). CONCLUSION: Adenoviral hIL-10 gene can significantly attenuate the severity of SAP rats, and can be used in the treatment of acute inflammation process.

OBJECTIVE: To study the effects of gut-derived endotoxin translocation and NF-kappaB activation on the aggravating mechanism of severe acute pancreatitis (SAP) and of treatment with pyrrolidine dithiocarbamate (PDTC) on rats with SAP. METHODS: SD rats were randomly divided into sham operation group (SO), SAP group, SAP + lipopolysaccharide(LPS) group, pyrrolidine dithiocarbamate (PDTC) treatment group and LPS group. Biochemical parameters and cytokines were examined in the serum. Multiple organs pathological slices were examined. Expression of NF-kappaB mRNA in the liver tissue was detected by RT-PCR. Activation of NF-kappaB by the method of streptomycin avidin-peroxidase (SP) and expression of NF-kappaB p65 protein and its binding activity were analyzed by Western blot and electrophoretic mobidity shift assay (EMSA). RESULTS: Compared with sham operation group, the concentration of TNF-alpha, alanine aminotransferase (ALT), and diamine oxidase (DAO) in serum significantly increased in SAP + LPS group (P < 0.05). Pathological changes were markedly observed in tissues and the expression of NF-kappaB mRNA in the liver significantly increased (P < 0.05) also, the activation of NF-kappaB and binding activity of NF-kappaB p65 protein in the liver markedly increased (P < 0.01) in SAP + LPS group. Treatment with PDTC markedly reduced concentration of ALT, DAO and TNF-alpha, and the expression of NF-kappaB, and the pathologic scores, as well as significantly decreased the expression of NF-kappaB p65 protein. CONCLUSION: The activation and overexpression of NF-kappaB may participate in the aggravating mechanism of SAP. Treatment with PDTC has a protective effect on multiple organs damage in SAP.

BACKGROUND AND OBJECTIVE: Since being named and reclassified by WHO in 1996, solid-pseudopapillary tumor (SPT) of pancreas has been recognized as a special entitative disease that is different from pancreatic cancer and should be recognized and treated more accurately in the surgical process. The clinic characteristics and surgical strategy on 25 cases of SPT of pancreas from the authors' center are discussed. METHODS: The clinical pathology and the surgical methods of 25 SPTs were retrospectively studied. The analyses were performed by the statistical software package SAS6.12. RESULTS: No tumor recurrences were found in all patients. There was significant difference between operative types in radical resection and the tumor position of the pancreas (P = 0.0011). The judgment on the tumor's boundary could directly affect the adoptable operative types (P = 0.0099). CONCLUSIONS: As a uniquely entitative disease, SPT is a kind of uncommon neoplasm with low-grade malignancy with a strong rate of occurrence in women. Surgical resection is most favorable in the treatment of SPT, which has excellent prognosis. The course of SPT, the possible malignant cells by the frozen section biopsy, and the tumor's boundary are important for operators to decide an operative scheme. SPT that has infiltrated contiguous vessels, organs, even with local liver metastasis should not be regarded as operative contraindication. The choice of the local tumor resection, the part of pancreas resection or radical resection depends on the judgment of the tumor's boundary, whereas operative types in radical resection depend on the tumor position of the pancreas.
