Eighty-four patients of severe pancreatitis were divided by different line of age and the mortality of patients with severe pancreatitis above and below the line was comared. The results showed that the 60-year of age was the age with the lowest mortality. The analysis of 35 patients with severe pancreatitis who were older than 60 years of age indicated that multiple gallstones was the most common cause initiating the disease. The common severe concurrent diseases were hypertension, coronary disease, cerebrovascular disease, and respiratory disease. Common organ failures were ARDS, shock and heart failure. The number of failed organs in elderly patients in the fifth and seventh day after admission was obviously more than that in young patients.

The etiology of acute pancreatitis is based on several causes, among which idiopathic nature (< 30%) is second to biliary stone disease (60-70%). It is still under debate whether alcohol as the main cause of chronic pancreatitic disease can cause acute pancreatitis. Based on Opie's "obstruction theory" of 1901 and experimental data, it is now widely accepted that the gallstone passage into or through the terminal biliopancreatic ductal system triggers acute (necrotizing) pancreatitis by causing pancreatic ductal obstruction. However, the sequential intracellular mechanisms in the pathogenesis of acute pancreatitis remain unclear. A co-localization hypothesis has been proposed to explain the premature intracellular activation of trypsinogen to trypsin: due to a yet unknown defect in the intracellular protein transport and sorting system within the acinar cell, lysosomal hydrolases (i.e. cathepsin B) and secretory proteins (i.e. trypsinogen) co-localize in a fragile postgolgi vacuole where activation can occur. In addition, alterations of exo- and endocytosis at the apical pole exist (i.e. secretion block). The pathophysiological events are characterized by local and systemic hypovolemia and (micro)circulatory failure aggravating necrosis, followed by ARDS, renal failure and several other severe complications (i.e. sepsis and DIC). The systemic overflow of proteolytic enzymes (i.e. PLA-2) and kinins plays a major role as mediating factor in severe cases, resulting in multiorgan failure.

We report a case of sero-negative tsutsugamushi disease diagnosed by polymerase chain reaction (PCR). A 54-year-old man who worked in Nagano prefecture presented with flu-like symptoms that did not respond to cephalosporin therapy. On admission to another hospital, chest roentgenography revealed abnormal shadows; liver dysfunction was also present. Despite therapy, the patient's condition gradually worsened and he was transferred to our intensive care unit. Erythema on all extremities and scabs on the right medial femoral region and the dorsum of the left foot suggested a diagnosis of tsutsugamushi disease. We administered minocycline and gave percutaneous cardiopulmonary support for adult respiratory distress syndrome. Despite all efforts, the patient died. Although serologic tests were not positive, Karp strains of R. tsutsugamuschi were identified on PCR amplification. Autopsy revealed evidence of acute hemorrhagic pancreatitis, which has not been reported previously in tsutsugamushi disease. We conclude that PCR techniques may be useful in confirming a diagnosis of early tsutsugamushi disease.

A 37-year old woman, presenting with severe hypercalcaemia-associated pancreatitis with pseudocyst formation, was admitted to intensive care because she developed ARDS with respiratory failure. Skeletal metastasis from non-small cell bronchial carcinoma were subsequently diagnosed. After she developed arterial occlusion in the lower limb, supportive treatment was withdrawn. Severe pancreatitis is an exceedingly unusual presentation of non-small cell bronchial carcinoma. Concepts of diagnostic and therapeutic strategies in the context of suspected unusual pathology, and the concept of futility are briefly discussed.

METHODS: Evaluated are surgical difficulties, management problems and weight loss in patients with distal gastric bypass as a revisionary procedure. Eighty patients were followed up to 3 years; four were lost to follow-up. Mean age was 43; mean prebariatric surgery weight 134 kg; height 1.65 meters; body mass index 40.1; ideal body weight 62.7 kg; excess weight 70.5 kg; per cent excess weight 214%. A 250 cm stomach-to-ileocecal valve segment of small bowel was used, and the biliopancreatic secretions were brought into the terminal ileum 100 6 in from the ileocecal valve. Mean pouch size was 63 cc; length of hospital stay 5 days; operative blood loss 616 cc; operative time 130 min. RESULTS: Intraoperative complications included three splenic injuries (without splenectomy). Early complications included one deep vein thrombosis, two marginal ulcers, one GI hemorrhage, one wound dehiscence, one pouch outlet obstruction and one pancreatitis. Late complications included: one death from protein malnutrition/ ARDS; 21 hypoproteinemia; six protein malnutrition, and of these, three had hyperalimentation; three cholecystitis; 27 anemia; 22 incisional hernia; two staple-line disruption (reoperated); 26 low serum iron; 11 prolonged (>6 months) diarrhea; three prolonged frequent vomiting; and two unrelated deaths (chronic myelogenous leukemia and amyotrophic lateral sclerosis). Mean excess weight loss was 83% at 12 months; 89% at 24 months; and 94% at 36 months. CONCLUSION: The distal gastric bypass is fraught with the operative and immediate post-operative complications experienced in any revisionary bariatric surgery. Distal gastric bypass is very effective in producing long-term weight loss. Nutritional problems are common but usually easily corrected. The most serious nutritional complication is protein malnutrition, which must be identified and corrected early. Success of this procedure is dependent upon patient compliance with proper nutrition and supplements, and regular office follow-up with monitoring of laboratory data. Patients who are noncompliant are at significant risk for complications.

Severe acute necrotizing pancreatitis is a disease that is caused by premature activation of pancreatic enzymes. Cytokine release contributes to systemic manifestations such as systemic inflammatory response syndrome (SIRS), multiple organ dysfunction syndrome (MODS), adult respiratory distress syndrome (ARDS), and sepsis. Diagnosis is based on a history of abdominal pain, laboratory values such as serum amylase and lipase levels, and CT scan. Medical management focuses on fluid and electrolyte balance, antibiotic therapy, pain control, and decreasing systemic complications. Surgery is indicated when infectious pancreatic necrosis has been identified. This article addresses incidence and etiology; pathophysiology; clinical manifestations; diagnostics; and medical and surgical patient care management.

This retrospective study describes 4 cases of canine babesiosis with histologically confirmed acute pancreatitis. In addition, 16 dogs with babesiosis are reported with serum amylase (>3500 U/l) and/or lipase (>650 U/l) activity elevations of a magnitude that would support a diagnosis of probable acute pancreatitis, although extra-pancreatic sources of the enzymes could not be excluded in these cases. Median time of pancreatitis diagnosis was 2.5 days post-admission, with primarily young (median age 3 years), sexually intact dogs affected. The development of pancreatitis was unrelated to the degree of anaemia at time of admission. In addition to pancreatitis, 80% of cases suffered from other babesial complications, namely icterus (13), acute respiratory distress syndrome (6), immune-mediated haemolytic anaemia (6), renal failure (3), haemoconcentration (2) and cerebral syndrome (2). Acute respiratory distress syndrome, renal failure and cerebral syndrome were associated with a poor prognosis, with 4 of the 5 dogs included in the overall 26% mortality rate having at least 1 of these complications. Haemolytic anaemia with ischaemia-reperfusion injury to the pancreas is proposed as a possible primary pathophysiological mechanism in babesial pancreatitis. Hypotensive shock, immune-mediated haemolytic anaemia, haemoconcentration and possibly altered lipid metabolism in babesiosis may also be involved. The previously postulated pro-inflammatory cytokine milieu of complicated babesiosis may underlie the progression, if not the primary initiation, of pancreatic pathology. Acute pancreatitis may represent the previously reported 'gut' form of babesiosis.

We investigated the effect of octreotide in the treatment of severe acute pancreatitis in a case-control study. Experimental and clinical studies on the effect of octreotide in the treatment of acute pancreatitis have shown controversial results. Since January 1992, we have been conducting a prospective randomized study on the effect of octreotide in severe acute pancreatitis, in three hospitals in Israel. The entering criteria included three or more of the Ranson prognostic signs and CT findings of severe pancreatitis. Patients were randomly assigned to conservative treatment either with or without octreotide (0.1 mg subcutaneously three times a day). The end points of the study included: complication rate (ARDS, sepsis, renal failure, pseudocyst, fistula, and abscess), length of hospital stay, and mortality. From January 1992 to December 1996, 60 patients entered the study. After evaluating the files, 10 patients were excluded due to failure to meet the entering criteria, incomplete data, or incorrect diagnosis. Of the remaining 50 patients, 25 were assigned to octreotide (treatment group) and 25 to conservative treatment only (control group). The two groups matched with regard to age, sex, etiology, and severity of the disease. The complication rate was lower in the treatment group with regard to sepsis (24% vs 76%, P = 0.0002) and ARDS (28% vs 56%, P = 0.04). The hospital stay was shorter in the treatment group (20.6 vs 33.1 days, P = 0.04). Two patients died in the treatment group and eight in the control group (P < 0.019). These results suggest that octreotide may have a beneficial effect in the treatment of severe acute pancreatitis.

Twenty six (7.3%) of a total of 356 patients with acute renal failure were found to have acute pancreatitis as the primary disease. Seventeen (65.4%) of them were males. Their mean age was 35.6 years. Clinically epigastric pain and tenderness were seen in all (100%); nausea vomiting (73%), low grade fever (50%), left sided pleural effusion (38.4%), haemopericardium (26.9%), shock (26.9%), pseudocyst (19.3%) and adult respiratory distress syndrome (7.6%) were the other major presenting features. Serum amnylase (100%), lipase (53.8%), triglycerides (53.8%) and blood sugar (38.5%) were raised in majority whereas serum calcium was detected to be below normal in 46.2% patients. Blood urea and serum creatinine were raised in all and hyperkalacmia was found in 50% patients. CT scan and USG abdomen showed bilateral enlarged kidneys (100%), pancreatic oedema (80.7%), necrosis of pancreas (19.3%) and pseudocyst (19.3%). Management included repeated peritoneal dialysis in all (100%) and surgical intervention in 53.8% patients with severe necrotising and haemorrhagic pancreatitis. All patients recovered from acute renal failure, but 26.9% patients expired due to complications of acute pancreatitis other than acute renal failure.

It is thought that tumor necrosis factor (TNF) plays an important role in pathogenesis of acute lung injury or ARDS. So we want to get insight into the relationship between intrapulmonary expression of TNF-alpha gene and lung injury during acute necrotizing pancreatitis (ANP). In our study, acute edematous pancreatitis (AEP) and ANP were induced in rats by caerulein and sodium taurocholate respectively. After acute pancreatitis was induced, serum TNF-alpha was assessed by ELISA assay while endotoxin was assessed by limulus lysate test. Intrapulmonary expression of TNF-alpha mRNA was detected by semi-quantitative reverse transcriptase-polymerase chain reaction (RT-PCR) technique. Moreover, content of pulmonary lesion was investigated and graded with microscope. It was found that TNF-alpha concentration in blood elevated markedly after acute pancreatitis was induced, especially in ANP group. Results of RT-PCR revealed that no TNF-alpha mRNA could be detected in lung tissue from those rats undergoing sham-operation, but marked expression appeared 1 hour after AEP or ANP was induced. Upregulation of expression of TNF-alpha gene in the early 3 hours was similar in the two groups with pancreatitis, and since then expression of TNF-alpha mRNA in ANP group was stronger than that in AEP group. Serum endotoxin increased significantly 6 hours after ANP was induced, with a higher level at 12 hour. However, there was no marked change of endotoxin level in AEP group and control group. It is noted that intrapulmonary expression of TNF-alpha gene in ANP group reached its peak as soon as serum endotoxin increased markedly. Lung damage in ANP group was more serious than that in AEP group significantly. Score of lung injury correlated well with TNF-alpha concentration in blood and expression of its gene in lung tissue in either AEP group or ANP group, as well as with serum endotoxin in ANP group. So overwhelm expression of some harmful cytokines like TNF-alpha in lung tissue may be the main cause of lung injury during acute necrotizing pancreatitis, and stimulation of endotoxiemia can at least partly explain the upregulation of expression of TNF-alpha gene.
