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.

An open-label prospective study was performed employing intramuscularly administered imipenem as an adjunct to surgery in 20 patients with acute cholecystitis and 24 patients with perforated or gangrenous appendicitis. Three (12.5%) septic failures occurred in appendicitis patients and 2 (10%) failures in cholecystitis patients. There were no deaths. Adverse effects were minor, and there was no toxicity. Although failures were not associated with in vitro resistance, Pseudomonas spp. were recovered from 2 of 3 appendicitis failures. Intramuscular imipenem appeared to be an effective single-drug antimicrobial when used as an adjunct to surgery in patients with acute cholecystitis or perforated appendicitis. It should be a more cost-effective alternative to the current multiple-drug therapy frequently employed in patients with intra-abdominal sepsis.

In vitro production of PGI2 in canine gallbladders subjected to hypovolemic shock and Escherichia coli sepsis was studied to determine whether a precursor above arachidonic acid in the cyclooxyenase cascade might be operative in the production of prostacyclin, which, in turn, may play a role in the pathogenesis of acute acalculous cholecystitis (AC). L-alpha-phosphatidylcholine (LaP), an arachidonic acid precursor, was used as the test agent. LaP did not stimulate PGI2 production from either gallbladder surface in the hypovelimic animals or the mucosa of the septic shock group. However, it did stimulate PGI2 production from the SS serosa compared with controls, 1375 +/- 432 versus 633 +/- 198 pg/cm2/min (P less than .05). In conclusion, lack of stimulation of PGI2 in the hypovolemic model suggests that PGI2 does not play a role in AC. Alternatively, it may play a role in preventing this disease process in septic shock. This study demonstrates the use of precursors of arachidonic acid and the cyclooxygenase pathway as active participants in the production of PGI2, although it is unclear whether the prostacyclin produced helps prevent AC in septic shock.

Surgical intervention after vascular surgery usually occurs as a result of bleeding or thrombosis, whereas general surgical problems requiring operation after vascular surgery are unusual. The purpose of this study was to review the results of operations for general surgical problems done soon after major vascular surgery. From January 1985 to December 1989, 1,236 major vascular procedures were performed, and 15 patients developed significant postoperative general surgical problems including perforated duodenal ulcer (2), perforated diverticular disease (2), evisceration and dehiscence (2), liver infarct (1), gangrenous cholecystitis (2), clostridial myonecrosis (1), pseudomembranous colitis (1), and small bowel obstruction (4). The overall mortality was very high (47%), and the chance of dying was significantly higher (p less than 0.05) if the initial vascular procedure was an emergency (100% mortality). All the patients who died (n = 7) succumbed to sepsis. There was a long delay in diagnosis in all groups; however, the delay did not correlate with mortality. Although this is a study of a small group of patients with a very heterogenous group of complications, several observations can be made: (1) a general surgical problem after vascular surgery carries a very high mortality; (2) general surgical complications in postoperative vascular patients in whom the initial procedure was an emergency are very poorly tolerated and almost uniformly lethal; and (3) these elderly patients have multiple medical problems and seem unlikely to tolerate any septic insult.

During 10 years 3000 patients were operated upon for chronic calculous cholecystitis. Twenty of these patients died during 30 days after operation, in 16 of them death resulted from incompetence of the vital organs. Endotoxicosis and polyorganic insufficiency after technically correct operations for chronic calculous cholecystitis are thought by the authors to be a variant of anaerobic infection with possible development of sepsis.

Patients with the acquired immune deficiency syndrome (AIDS) frequently develop hepatic dysfunction. Although hepatic injury may indirectly result from malnutrition, hypotension, administered medications, sepsis, or other conditions, the hepatic injury is frequently due to opportunistic hepatic infection, directly related to AIDS. Infection with Mycobacterium avium intracellulare typically occurs in patients with advanced immunocompromise and with systemic symptoms due to widely disseminated infection. In contrast, hepatic tuberculosis often occurs with less advanced immunocompromise. Cytomegaloviral infection may produce a hepatitis. Cytomegaloviral and cryptosporidial infections have been implicated as causes of acalculous cholecystitis and of a secondary sclerosing cholangitis. About 10-20% of patients with AIDS have chronic hepatitis B infection. These patients tend to develop minimal hepatic inflammation and necrosis. The clinical findings in patients with hepatic cryptococcal infection are usually due to concomitant extrahepatic infection. Hepatic histoplasmosis usually develops as part of a widely disseminated infection with systemic symptoms. Hepatic involvement by Kaposi's sarcoma is rarely documented ante mortem because an unguided liver biopsy is an insensitive diagnostic procedure. Patients with non-Hodgkin's lymphoma of the liver typically have lymphadenopathy, hepatomegaly, and systemic symptoms. As a pragmatic approach, patients with liver dysfunction and HIV-related disease should have a sonographic or computerized tomographic examination of the liver. Patients with dilated bile ducts should undergo endoscopic retrograde cholangiopancreatography because opportunistic infection may produce biliary obstruction. Patients with a focal hepatic lesion should be considered for a guided liver biopsy. Patients with a significantly elevated serum alkaline phosphatase level should be considered for a percutaneous liver biopsy. When performed for these indications, liver biopsy will demonstrate a significant disease involving the liver in about 50% of patients with AIDS and in about 25% of patients who are HIV seropositive but who are not known to have AIDS. The clinical impact of a diagnostic biopsy is blunted by a lack of efficacious therapy for many opportunistic infections.

We report on the rare association of Hodgkin's disease with systemic lupus erythematosus. Two years after the diagnosis of systemic lupus erythematosus, the patient developed upper abdominal pain, jaundice, splenomegaly, and fever of unknown origin. He had a rapidly fatal clinical course, despite being treated for systemic lupus erythematosus, cholecystitis, and possible sepsis. Autopsy revealed Hodgkin's disease, lymphocyte-depletion type, involving lymph nodes, liver, spleen, and bone marrow. The awareness of the association of Hodgkin's disease with systemic lupus erythematosus and its modes of presentation will help in the early diagnosis and management of such patients.

Clinical and bacteriological data from 55 patients who developed septicemia within 3 days after ERCP were collected. Forty-four patients presented with septicemia after therapeutic endoscopy, with incomplete drainage in forty, eight after diagnostic ERCP performed in obstructed bile ducts in another center and not followed by endoscopic therapy, and three with a normal common bile duct after diagnostic ERCP. The incidence of septicemia is significantly higher in cases of malignant obstruction than in benign obstruction (21% vs 3%; p less than 0.01), due mainly to the problems of drainage associated with tumoral infiltration. Forty-eight patients (87%) had incomplete bile duct drainage when they developed septicemia, and among the seven remaining cases, 3 had cholecystitis and 3 abscesses in the biliopancreatic area. Previous diagnostic ERCP without drainage was also clearly associated with septicemia after therapeutic ERCP. The most commonly isolated bacteria from blood and bile cultures were Pseudomonas aeruginosa and Escherichia coli. P. aeruginosa was observed mainly in patients referred from other centers after previous diagnostic ERCP, and was unusual in patients without previous ERCP. It is associated with problems in the disinfection of the scopes. Six deaths were attributed to sepsis, always in patients with incomplete biliary drainage which could not be improved. In most of the cases, septicemia after ERCP is related to incomplete bile duct drainage, and in some cases, to biliopancreatic infected collections. Careful disinfection of the endoscopes and other endoscopic devices is mandatory to avoid an unacceptably high rate of P. aeruginosa infection.

Surgical cholecystostomy is a palliative treatment for cholecystitis and distal biliary obstructions when the general condition of the patient does not allow complex techniques. Percutaneous cholecystostomy (PC) guided by ultrasonography is an alternative to that procedure as well as a method of direct access to the biliary tract for diagnostic examinations (bacteriologic study of bile and percutaneous cholangiography). During one year, 9 female patients, mean age 74 (49 to 90) underwent this approach; 5 patients had cholecystitis, 2 were suspicious of biliary sepsis and 2 had angiocholitis. Because of poor general condition, no other approach was possible in any of the cases. There were no relevant complications. All 5 cases of cholecystitis improved after the procedure although 3 patients died within 30 days of causes unrelated to PC. In two cases biliary sepsis was ruled, and the probe was withdrawn, without complications. The two patients with angiocholitis improved significantly; in both cases it was shown that the cause was cholelithiasis: later on, they were treated by different methods (endoscopic sphincterotomy in one case and surgery in the third case). These preliminary results suggest that PC guided by echography should be included as a routine therapeutic and diagnostic method in the management of digestive diseases.

Acute acalculous cholecystitis is a virulent disease of uncertain etiology observed most commonly in critically ill patients. Although the precise mechanism is unknown, the most commonly postulated theories regarding its pathogenesis are bile stasis, sepsis, and ischemia. The role of ischemia in this process, whose etiology is multifactorial, has been difficult to elucidate. Consequently, we report two patients who developed acute acalculous cholecystitis without apparent risk for the disease other than severe visceral atherosclerosis. Both patients had symptomatic mesenteric vascular disease requiring revascularization and developed fulminant acalculous cholecystitis temporally related to exacerbation of their visceral ischemia. These cases suggest that patients with visceral atherosclerosis may be at increased risk for acute acalculous cholecystitis, perhaps due to impaired mucosal resistance when other factors, such as bile statis and sepsis, are also present.
