Sixty-three patients with severe acute pancreatitis have been studied. Pancreatitis was associated with biliary tract disease in 23 patients (36.5%) and with alcoholism in 21 (33.3%). It occurred post-operatively in 9, and was associated with other conditions in 10. We evaluated the Ranson prognostic signs (RPS) with the appearance of complications. 36 patients (57.2%) had 3-4 RPS, 9 (30.2%) had 5-6 RPS and 8 (12.6%) had 7 or more RPS. Diagnostic laparotomy was performed in 11 patients (17.5%). 55 patients were operated one or more times due to failure of medical treatment and/or local and septic complications. The most frequent complications were pancreatic abscess (60.3%), sepsis (58.7%) and pulmonary insufficiency (52.4%). Renal failure occurred in 26 patients and 9 required dialysis. Of the patients with renal failure, 84.6% (22/26) had 4 or more RPS; 78.4% (29/37) of those with sepsis and 71.6% (27/38) of those with pancreatic abscess also had 4 or more RPS. The mean duration of hospitalization of survivors was 58 +/- 30 days. Overall mortality was 28.6%. We conclude that RPS are helpful to predict complications in patients with severe pancreatitis.

In patients with severe acute pancreatitis, the most important diagnostic goal is differentiation between the interstitial-edematous and the necrotizing type of acute pancreatitis. Surgical management in patients with proven necrotizing pancreatitis is indicated in patients who develop surgical acute abdomen, sepsis, shock syndrome, multisystemic organ failure syndrome, persistent or progressive despite maximum intensive care. The most appropriate procedure for surgical management of pancreatic necrosis is the careful removal of necrosis and preservation of vital pancreatic tissue. Necrosectomy supplemented by postoperative closed continuous lavage of the lesser sac is a procedure that offers the advantages of debridement of devitalized tissue only, and the non-surgical removal of necrotic tissue and bacterially and biologically active compounds. In comparison with a reoperation protocol, necrosectomy and continuous lavage reduce the reoperation rate as well as the need for tracheostomy. In a prospectively treated series of patients suffering from necrotizing pancreatitis, hospital mortality was 8.4% and the reoperation rate 27%. Any tissue becoming necrotic in the postoperative course of disease is rinsed with lavage fluid, thus obviating the need for repeated surgical reoperation in most patients. Local lavage is achieved by the insertion of two, in some cases five, large double-lumen tubus and the use of 8 liters (median) of lavage fluid per day.

The most important diagnostic step in the management of patients with severe acute pancreatitis is discrimination between interstitial-edematous pancreatitis and necrotizing pancreatitis. In this respect, laboratory measures like CRP, LDH, and antiproteases, and the application of contrast-enhanced CT are highly sensitive methods. Surgical decision-making should be based on clinical, bacteriological and contrast-enhanced CT data. Persistent or progressive systemic or local organ complications occurring despite ICU treatment for a minimum of three days are indicators for surgical management of necrotizing pancreatitis. Patients suffering from sepsis syndrome, cardiovascular shock, multisystemic organ failure syndrome, or surgical acute abdomen should be treated surgically early in the course of the disease. The use of a major pancreatic resection for the surgical management of necrotizing pancreatitis should be excluded from treatment protocols. Carefully performed necrosectomy or debridement, in combination with continuous or repeatedly applied surgical evacuation techniques for necrotic tissue, bacteria, and biologically active compounds, has proved to be very effective in experienced treatment centers. Necrosectomy and postoperative continuous local lavage is a well-adapted, safe, and atraumatic procedure. It results in a hospital mortality of less than 10% in patients with necrotizing pancreatitis.

The variable clinical presentation and natural history of acute pancreatitis are illustrated by case reports, namely a case with a falsely positive diagnosis of biliary pancreatitis, a case with acute interstitial pancreatitis of biliary origin, a patient with early and severe late systemic complications and with sterile necrotizing pancreatitis necessitating operative debridements twice, a patient with acute pancreatogenic ascites and ARDS requiring drainage and respiratory supportive care, a patient with biliary pancreatitis and operation for necrotizing cholecystitis, with a further, late intervention for pancreatic abscess, and a patient with internal drainage for a pseudocyst, complicated by acute biliary pancreatitis due to cholesterolosis of the gallbladder. Modern clinico-pathological classification of acute pancreatitis and modern definitions of pancreatic sepsis are important for determining prognosis and adequate treatment.

On the basis of the observation that serum levels of phospholipase A2 (PLA2) are elevated in pancreatitis and systemic sepsis, and the association of these conditions with the subsequent development of acute lung injury, the present investigation examined the structural and physiologic consequences of intratracheal administration of PLA2 to adult male rats. Rats received direct intratracheal instillation of either control vehicle or 40,000 units/kg of PLA2 repurified from Naja naja venom. Animals treated with PLA2 showed higher cumulative mortality (33% versus 0%, n = 79; p less than 0.01) than did their control littermates. The PLA2-treated animals showed histologic evidence of acute lung injury characterized by interstitial and alveolar edema, accumulation of inflammatory cells, and alveolar wall thickening, which reached maximal severity 48 h after enzyme instillation. Forty-eight hours after PLA2 administration experimental animals had lower arterial oxygen tensions (73.9 +/- 7.66 mm Hg versus 96.7 +/- 2.52 mm Hg, mean +/- SEM; p less than 0.01), higher alveolar-arterial oxygen gradients (35.3 +/- 6.3 mm Hg versus 18.8 +/- 1.42 mm Hg, p less than 0.01), and higher wet-dry lung weight ratios (5.08 +/- 0.26, mean +/- SEM, n = 7 versus 3.29 +/- 0.08, n = 3; p less than 0.002) than did control animals. Lung lavage from experimental animals 48 h after PLA2 instillation showed increased total cell counts [(26.6 +/- 5.04) x 10(6) cells versus (4.69 +/- 1.48) x 10(6) cells; p less than 0.01], an increased percentage of neutrophils (34.2 +/- 4.6% versus 1.25 +/- 0.25%, mean +/- SEM; p less than 0.01), and increased protein concentrations in lavage fluid (0.38 +/- 0.06 mg/ml, mean +/- SEM, n = 4 versus 0.27 +/- 0.02 mg/ml, n = 5; p less than 0.05). The histologic and physiologic abnormalities had largely resolved by 240 h. These results suggest that PLA2 may be a potent mediator of lung inflammation and that intratracheal administration of PLA2 to adult rats may provide a useful experimental model of acute lung injury.

116 patients admitted for acute pancreatitis were analysed. In 80% of patients presenting biliary pancreatitis cholecystectomy and bile duct exploration was the prevalent treatment, in 7.8% pancreatic necrosis was removed. Indications to operate on patients with non-biliary pancreatitis included enhancement of pancreatic inflammation revealed by computed tomography and multi-organ-failure or sepsis complicating the course of the disease (incidence of laparotomy 20.3%, incidence of necrosectomy 12.3%). According to this concept 2 out of 3 patients presenting partial pancreatic necrosis recovered without operation. Lethality of patients with acute necrotizing pancreatitis (6.9%) was accounted 25%, over-all mortality 6%. Methods used for classification of severity of acute pancreatitis (Mainz classification, Ranson criteria) turned out to be not reliable. Clinical staging of pancreatitis was not in accordance with intraoperative findings in 51.9% of cases. As a prerequisite for stage-dependent therapy new objective data to access severity and clinical course of acute pancreatitis have to be worked out.

35 consecutive pancreatic trauma were operated (21 blunt trauma and 14 penetrating injuries). 30 patients were operated in emergency and diagnosis was suspected before laparotomy in only one case. 12 patients had a superficial lesion, 21 had a wirsung disruption (14 in the left pancreas, 7 in the right pancreas), 2 had a diffuse pancreatitis. For the 30 patients operated in emergency, 20 had a conservative treatment, 10 had a resection. 5 patients died (14.2%), from exsanguination (2 cases), missed diagnosis or inadequate treatment (2 cases), sepsis after adequate management (1 case). Our experience suggests that an aggressive diagnosis management in emergency, with pre or pre-operative wirsungography, could determined with precision the type of the lesion and permit an adequate management, to decrease mortality.

Eighteen consecutive patients with sepsis due to surgically confirmed peripancreatic necrosis extending diffusely into the retroperitoneal fat were treated in our hospital from 1980 to 1987. Management consisted of early retroperitoneal debridement of necrotic tissue and drainage through lumbar incisions. Enteral nutrition was implemented in all patients 3-8 days after their first surgery. A total of 40 reoperations were required--an average of 2.6 per patient. Complications included respiratory failure (17), renal failure (4), gastrointestinal bleeding (4), retroperitoneal bleeding (1), and gastrointestinal fistulas (6). Four (22%) of the 18 patients died; the major cause of death was multiple organ failure secondary to sepsis. Before 1980, all patients with severe pancreatitis treated in our hospital died, despite the use of different management techniques. The use of the extraperitoneal route for early debridement of necrotic tissue and to avoid contamination of the peritoneal cavity has substantially reduced the mortality associated with peripancreatic necrosis in our hospital. The mortality in this series of patients (22%) compares very favorably with that reported in studies of similar patients.

Frequently, several multiple abdominal reexplorations are needed in patients with acute necrotizing hemorrhagic pancreatitis (ANP) or with persistent intraabdominal sepsis (PIAS). Residual undrained necrotic and septic foci lead to multiple organ failure. To provide wide-open drainage of the abdominal cavity, since 1985 we have performed sequential abdominal reexploration with the zipper technique (SARZT) in 24 patients. Apache II score was used to evaluate expected mortality. In the pancreatic necrosis group, with a mean Apache II score of 31, the expected and the observed mortality were 70% and 29%, respectively. In the PIAS group, with a mean Apache II score of 30, the expected and observed mortality were 60 and 28%, respectively. These results are attributed to the sequential reexploration of the abdominal cavity that permits excision and drainage of necrotic and septic foci.

Without surgical debridement in patients with infected pancreatic necrosis, survival can not be expected. Previous surgical series reported postoperative survival in the range of 50%; however, more recent reports demonstrate improved mortality of 10% to 20%. Despite the demonstrated advances in surgical management, much remains to be done. Ongoing sepsis and the multiorgan failure syndrome (including ARDS, renal, and hepatic failure) are frequently part of the terminal phase of necrotizing pancreatitis, and further declines in mortality await future improvements in supportive therapy for overwhelming sepsis. Finding a means to prevent secondary infection of necrotizing pancreatitis would also have a very significant impact on survival. Defining the various form of severe acute pancreatitis and its infectious complications by dynamic pancreatography and CT-directed aspiration will permit meaningful trials of new methods to treat these unfortunate patients.
