Ultrasonic assessment of the pancreas is rendered difficult by interposed gas-containing loops of bowel and stomach. In 50% of the cases, meteorism and ileus prevent the diagnosis of acute pancreatitis. In the case of chronic pancreatitis, focal pancreatitis and carcinoma of the pancreas, too, further diagnostic procedures (CT, ERCP, fine-needle aspiration) are required. As a rule, the caliber of the pancreatic duct can readily be assessed, and may, for example, indicate a carcinoma in the head of the pancreas. Splenomegaly and focal or diffuse parenchymal lesions are detectable by ultrasonography, although an etiological differentiation is not usually possible. The most common lesions are the so-called "bland" splenic cysts. Of importance is the diagnosis of rupture of the spleen, which requires immediate treatment.

The authors describe 11 cases of acute abdomen they observed during a two-year period mainly after abdominal operations. The male/female ratio was 6:5, the mean age 59 years with a range from 20 to 75 years. The mean period which had elapsed after the primary operation was 18.5 days. The authors describe four cases with ileus due to adhesions, three cases of volvulus of the small intestine, a stress ulcer, gangrenous appendicitis, acute cholecystitis and adnexitis. In general it is assumed that the most frequent acute abdomen during the post operative period is ileus due to adhesions, postoperative pancreatitis or stress ulcers are less frequent. Extremely rarely the cause of complaints is inflammatory acute abdomen of a different nature which is an unexpected finding during surgical revision. It is dangerous due to the atypical course and the fact that symptoms are masked by manifestations of the receding postoperative state. In the literature the aetiopathogenesis of such rare conditions is most frequently associated with impaired tissue perfusion due to an inadequate blood flow, general tissue hypoxia due to hypovolaemia, protracted postoperative shock, rigid vascular walls which are incapable of adequate reaction to acute deviations of circulatory demands. Despite this these conditions develop more rarely than corresponds to the coincidence of these general relatively frequent adverse factors. Severe immunosuppression is also observed much more frequently in surgical patients than these rare complications. The authors observed the incidence of these cases of acute abdomen at a ratio of 1:2000 which corresponds roughly to data in published work. Seeking the solution in immunity disorders does not explain this problem.(ABSTRACT TRUNCATED AT 250 WORDS)

From March 1988 to March 1990, 11 children with cystic fibrosis (age 5-15 years) underwent combined heart-lung transplantation at our institutes. Maintenance immunosuppression consisted of cyclosporin and azathioprine with corticosteroids and antithymocyte globulin used perioperatively and during rejection episodes. Six patients (55%) survive from 1.5-23 months all of whom have improved life quality. Actuarial survival to 1 year was 55%. At six months after transplant, mean forced expiratory volume at one second was 73.5% of predicted normal, compared with 25% before transplant. There was one perioperative death, three later deaths associated with obliterative bronchiolitis at two, eight, and nine months, and one from mediastinitis at four months. Of the 15 children accepted for transplantation but not receiving grafts, 10 have died (eight within four months of being placed onto the transplant list). Early postoperative problems included acute reversible rejection (n = 10), meconium ileus equivalent (n = 3), and pancreatitis (n = 1). There was a high incidence of later pulmonary rejection with a mean of 5.7 episodes per patient in the first six months. Pulmonary infection occurred relatively infrequently, with Pseudomonas aeruginosa being the most common pathogen. Persistent diabetes mellitus requiring insulin occurred in four and systemic hypertension developed in one.

The management of 23 patients treated for choledochal cysts at the Oregon Health Sciences University between 1969 and 1990 is reviewed. The median age was 27 years, with a range from 1 month to 90 years. Seventy-eight percent of patients presented with abdominal pain, and 35% were jaundiced. Three patients presented with cholangitis, two with cyst rupture, and one with recurrent pancreatitis. Nine patients had had previous biliary surgery. The diagnosis was made in all patients with ultrasound and/or cholangiography. Fifteen patients (65%) had type I cysts, 2 had a type II cyst, 5 (22%) had type III cysts, and 1 had a type IV cyst. Stones were present in four (17%) cysts, and all excised cysts were benign. Seventeen patients with type I and II choledochal cysts had complete cyst excision and choledochoenterostomy. Four of five patients with type III cysts had endoscopic cyst incision and drainage, while the fifth patient had transduodenal cyst excision and sphincteroplasty. The patient with a type IV cyst had extrahepatic cyst excision and choledochojejunostomy. There were no operative deaths. Two postoperative complications occurred: cholangitis and a prolonged ileus. All patients had resolution of their pain and jaundice. Two patients had late cholangitis. Cyst excision and choledochojejunostomy are the treatment of choice for types I and II choledochal cysts. Extrahepatic cyst excision and choledochojejunostomy may be adequate treatment for type IV cysts. Endoscopic incision and drainage is appropriate for selected patients with type III cysts.

Painless acute hemorrhagic pancreatitis, manifested only by an ileus, is described in two of nine patients after ingestion of parathion, a poisonous anticholinesterase insecticide. Other investigators have shown in animal experiments that parathion increases pancreatic intraductal pressure and stimulates pancreatic secretion. Such described cases may be designated pathologically as clinical examples of acute obstruction pancreatitis. Hemoperfusion is usually chosen to treat parathion intoxication, but carries the risk of causing hemorrhages in acute hemorrhagic pancreatitis. Clinically, it is therefore important to determine, by way of enzyme estimations and imaging procedures, whether acute pancreatitis has occurred following parathion intoxication, so that the prognosis for the poisoned patient is comprehensive enough and the antidated measures applied do not aggravate the pancreatic condition.

A 48-year-old patient presented with a 24 hour history of diffuse abdominal pain and diarrhea. Based on elevated serum amylase and lipase levels, a CT-scan, and a history of chronic alcohol intake, acute alcoholic pancreatitis was diagnosed. The patient clinically improved under conservative therapy, but after restarting enteral nutrition on the fourth day, he developed full blown mechanical ileus. Intraoperatively, an adhesive band and acute edematous pancreatitis and fat necrosis was found. Retrospectively, the initial clinical symptoms and plain abdominal x-ray findings suggest coincidence of obstructive ileus and acute pancreatitis. We hypothesize that obstructive ileus had triggered pancreatitis.

We have described a spectrum of pancreatic surgery after cardiopulmonary bypass. At one end is a subclinical lesion which was manifested only by elevations in serum isoamylase levels (27 percent of patients) and increased ribonuclease levels (13 percent of patients) in asymptomatic patients followed after cardiac surgery. At the other end is a severe and often lethal necrotizing pancreatitis. Acute necrotizing pancreatitis was found at autopsy in 25 percent of 138 patients who died after cardiac surgery, and it correlated strongly with low output, acute tubular necrosis, and infarction of the liver, spleen, or bowel. It was the principal cause of death in 4 percent of these patients. In addition, 24 percent of 38 nonsurgical patients who died from cardiac failure and hypoperfusion had acute pancreatitis at autopsy, whereas acute pancreatitis was not observed in 55 nonsurgical patients who died without a significant period of low output. Acute pancreatitis was recognized postoperatively in 12 patients (0.2 percent). Three had mild pancreatitis, and all responded well to conservative therapy. In nine patients, fulminant necrotizing pancreatitis developed. Their courses were characterized by significant early postoperative hemodynamic compromise, abdominal distention, ileus, fever, and episodes of late vascular instability associated with hypocalcemia. The diagnosis of pancreatitis was usually missed because of the absence of pain, tenderness and hyperamylasemia. The diagnosis was confirmed at laparotomy in eight patients and at autopsy in one. The only two survivors among the nine with severe cases had aggressive mobilization, debridement, and wide drainage of the necrotic pancreas. We suggest that a mild subclinical injury to the pancreas may occur as a consequence of cardiopulmonary bypass and may progress to severe ischemic necrosis if hypoperfusion follows in the postoperative period, the presentation of necrotizing pancreatitis may be atypical in the cardiac surgical patient and should be considered if nonspecific abdominal symptoms are present, and aggressive debridement and drainage may be the optimal treatment for aggressive forms of this disease.

A multi-institutional study to evaluate the efficacy, clinical application, and safety of extracorporeal shock-wave lithotripsy (ESWL) with the Dornier HM-3 or HM-4 lithotripter for bile duct calculi (BDC) was initiated in September, 1987. Symptomatic patients who entered into this prospective trial had BDC in the common bile duct and/or the intrahepatic, cystic or lobar ducts of the liver that were inaccessible or untreatable by papillotomy or percutaneous stone extraction. The study excluded gallbladder stones. Nasobiliary (54.4%) or transhepatic catheters (10.5%) and T-tube or cholecystostomy tubes (17.5%) or combinations (14.0%) permitted access for radiographic contrast to allow fluoroscopic monitoring of stone position and fragmentation. Exclusion criteria included pregnancy, failure to localize the stone, disturbances of coagulation, pacemakers, or vascular aneurysms or large bones that lie in the focal axis of the shock waves. Eleven institutions treated 42 patients (23 male, 19 female) with BDC; age range was 25 to 95 years (mean +/- SD, 73.5 +/- 13.8) and ASA risk category was 1 to 4 (mean, 2.3 +/- 0.8). Fourteen patients (33.3%) had a single BDC; 28 had 2 to 8 stones (mean, 2.7 +/- 1.8) ranging in size from 6 mm to 30 mm (mean, 18.5 +/- 6.4). The majority (66.7%) of patients were postcholecystectomy. The 42 patients received 57 ESWL treatments consisting of 600 to 2400 shocks per treatment (mean, 1924 +/- 289) at 12 to 22 kV (mean, 18.5 +/- 1.9) administered over 20 to 125 minutes (mean, 52.9 +/- 20.8). General anesthesia was used in 32% of the treatments; the majority were treated with epidural or regional block (42.1%), local infiltration (28.1%), or intravenous sedation (38.6%). Fifteen patients (35.7%) required two ESWL treatments. Stone fragmentation occurred in 94.6% of evaluable patients and in 90.4% of ESWL treatments, respectively; however, BDC fragments remained in 59.5% of patients 24 hours after treatment (diameter less than or to 3 mm, 12%; 4 to 9 mm, 16%; greater than or equal to 10 mm, 68%). Some patients (50%) required adjunctive procedures to achieve stone removal that included endoscopic extraction (n = 10; 47.6%), biliary lavage (n = 8; 38.1%), endoscopic bile duct prosthesis (n = 1; 4.8%), and operation (n = 2; 9.5%). ESWL treatment complications during hospitalization were observed in 15 patients (35.7%) and were present in four (9.5%) at discharge. Complications included macrohematuria (5%), biliary pain (15%), biliary sepsis (5%), hemobilia (10%), ileus (2.5%), and adverse pulmonary changes (7.5%). One patient developed pancreatitis before ESWL at ERCP that resolved prior to discharge.(ABSTRACT TRUNCATED AT 400 WORDS)

Three patients developed pancreatitis and duodenal obstruction after aortic surgery, contributing significantly to stormy postoperative courses. Serum amylase and lipase levels should be obtained in any patient who has duodenal obstruction and/or persistent ileus after aortic surgery. If these enzyme levels are elevated, computerized tomography of the abdomen should be performed to implicate or exclude pancreatitis as a possible cause.

With the advent of cyclosporine A, heart transplantation has become a widely accepted treatment for patients with end-stage cardiac disease that is not amenable to medical or surgical treatment. Between July 1982 and December 1985, 86 heart transplantations were performed at the Texas Heart Institute with cyclosporine A and prednisone used for immunosuppression. Thirty patients had complications requiring general surgical consultation. The pancreas and biliary tracts were most commonly affected. Pancreatitis developed in sixteen patients; five patients required operative intervention, resulting in a 40% mortality rate. Five of nine patients with cholecystitis required cholecystectomy. All patients survived the procedures. Other gastrointestinal complications included colonic ileus, bowel perforation, gastrointestinal bleeding, gastric outlet obstruction, and perirectal abscess. Patients who have undergone cardiac transplantation are susceptible to life-threatening infections and are at risk of serious complications requiring general surgical intervention. Better results can be obtained in these complex clinical situations when complications are identified early and managed aggressively through the adjustment of immunosuppression, adequate selection of antimicrobial agents, and proper timing of surgical intervention.
