Pancreatic complications following cardiopulmonary bypass are infrequent but are associated with high mortality. All cases of pancreatic complications following cardiopulmonary bypass from 1972 to 1987 at a single institution were retrospectively reviewed. Of 5621 patients who underwent cardiopulmonary bypass, 25 (0.44%) sustained pancreatic complications. There were 15 cases of acute pancreatitis and 10 cases of pancreatic necrosis, with 11 deaths in the group reviewed, a mortality rate of 44%. Factors that were correlated with mortality associated with pancreatic complications in this study include preoperative hypotension, preoperative use of inotropic agents, and renal failure (preoperative and postoperative). Factors that have been previously associated with mortality from pancreatic complications in other studies, such as fluid sequestration, respiratory failure, sepsis, tachycardia, hypocalcemia, age greater than 55 years, and abnormal laboratory findings, were not found to be significantly associated with mortality in this study. Of the five patients for whom complete data were available, not one patient received greater than 800 mg of calcium per square meter of body surface area in the perioperative period. While the exact mechanism of pancreatic injury remains unclear, based on experimental studies and clinical correlation, it is likely that pancreatic ischemia remains a significant contributing factor. We conclude that no factor specifically associated with cardiopulmonary bypass was correlated significantly with mortality.

The case of a patient who had Zollinger-Ellison syndrome caused by a primary peripancreatic lymph node gastrinoma is presented. Accompanying diffuse pancreatic islet cell hyperplasia, a well-documented occurrence in hypergastrinemia, was present. A perforated esophageal ulcer in a Barrett's esophagus led to right-sided necrotizing pleuritis, septicemia, and death. The diffuse parathyroid hyperplasia also noted in the patient is thought to be secondary to chronic hypertensive renal failure rather than MEN-I syndrome.

We describe a case of Pseudallescheria boydii endocarditis involving the pulmonic valve in an orthotopic liver transplant recipient. The patient required transplantation because of hepatic failure secondary to chronic active hepatitis B. His postoperative course was complicated by surgery for gastric and duodenal ulcers, persistent fever, and, ultimately, sepsis leading to oliguric renal failure. Two days before death, the patient experienced complete heart block, and an echocardiogram revealed pulmonic valve thickening and an endocardial mass along the left side of the septum. At autopsy the patient was found to have a vegetation on the pulmonic valve and a septal abscess. There were multiple fungal emboli found throughout other organs, and P. boydii was obtained on culture. This unique association between pulmonic valve endocarditis and myocardial septal abscess is discussed. In addition, review of the five previous cases of P. boydii endocarditis reveals that this rare infection is associated with immunosuppression and prosthetic devices.

Since the development of recombinant DNA technology, there has been a rapid expansion of research concerning the use of recombinant DNA synthesized human growth hormone (rhGH) for the treatment of clinical disorders. rhGH has been used to treat patients with acute catabolic stress caused by surgery, trauma and sepsis, children with chronic renal insufficiency and impaired growth, patients undergoing maintenance hemodialysis who are malnourished, and individuals on weight reduction diets. These studies indicate that rhGH enhances protein balance in acutely stressed patients and in malnourished maintenance hemodialysis patients, promotes catch-up growth in children with chronic renal failure, and may reduce protein wasting and enhance lipolysis in obese individuals on weight reduction diets. Experimental studies suggest that in addition to enhancing anabolism, rhGH may increase both immune function and the rate of wound healing. Many, but not all, of the effects of rhGH are mediated through insulin-like growth factor I (IGF-I). For example, the hyperglycemic and lipolytic effects of rhGH do not seem to be caused by IGF-I. Animal or human studies suggest that with severe malnutrition or severe sepsis, rhGH treatment may neither increase serum IGF-I levels nor promote anabolism. These observations provide a rationale for administering IGF-I as an anabolic hormone for severely malnourished or septic patients with renal failure. Further studies will be necessary to examine both the short-term and long-term potential benefits and adverse effects of rhGH or rhIGF-I treatment in these conditions.

We studied a total of 100 patients (46 men, 54 women) with renal failure requiring hemodialysis therapy by using double lumen catheter for temporary vascular access through the internal jugular vein. Fifteen patients had acute renal failure and 85 patients had end stage renal disease (including 27 cases of DM nephropathy). The mean length of time the catheter was in situ was 18.7 +/- 11.1 days (2-67 days); the mean frequency of the hemodialysis performed through this access was 7.8 +/- 4.6 (1-27). Recirculation rate was 7.19 +/- 2.68% (3.2-10.7%). The blood flow during hemodialysis was 180-200 ml/min. There was no catheter related mortality. The most common complication was catheter related septicemia (4%). Local infection of the catheter entry site occurred in 3 cases. Inadequate blood flow was detected in 3 cases. Two episodes of arrhythmia (atrial premature contractions, short runs of ventricular tachycardia) developed during the first hemodialysis procedure. Hematoma due to accidental puncture of the carotid artery was noted in one case. Neither pneumothorax nor hemothorax was detected. Our experiences revealed that the percutaneous internal jugular vein catheterization with a double lumen catheter is a safe and efficient temporary vascular access for hemodialysis.

Between January 1988 and January 1992, 65 patients (pts) had a ventricle assist device (VAD) inserted in our clinic. In 24 pts a VAD was applied because of primarily unsuccessful weaning from cardiopulmonary bypass (Group A). In a further 24 pts (Group B) a VAD was installed for the therapy of refractive cardiogenic shock (CS) after initially successful cardiac surgery (n = 21) and after acute myocardial infarction (n = 3). Twelve pts were bridged to heart transplantation (Group C) and five had a VAD inserted for various other reasons (Group D). In 36 (55.4%) of the total 65 pts a nonpulsatile VAD (Biomedicus 540) was used: 10 in Group A; 20 in B, 3 in C and 3 in D. In 29 pts (44.6%) a pulsatile VAD (Abiomed BVS 5000) was used: 14 in Group A, 4 in B, 9 in C and 2 in D. Weaning rate and long-term survival rates were 50% and 46% respectively in Group A and 38% and 42% in Group B. Seven pts from Group C were transplanted and six are long-term survivors. Two pts (40%) in Group D were discharged from hospital. Major postoperative complications were bleeding (46%), thromboembolism (14%), multiple organ failure (11%), renal failure (11%), arterial embolism (4.6%), sepsis (3%). The results indicate that application of a VAD can be recommended in pts with postcardiotomy CS to allow recovery of cardiac function and in pts with irreversible ventricular damage as bridging to HTX.

Hemofiltration was performed in 15 patients with refractory congestive heart failure. All of these patients had oliguria, although intensive treatment with diuretics, digitalis, vasodilators, and catecholamines was prescribed. Hemofiltration was performed under hemodynamic monitoring in 14 patients. The water removal by hemofiltration decreased pulmonary arterial pressure, pulmonary capillary wedge pressure and right atrial pressure. Despite these hemodynamic improvements, nine patients (60%) died within one month after the start of hemofiltration; the causes were fatal arrhythmia in three, renal failure in two, sepsis in one and irreversible cardiogenic shock in three. Oliguria for over 15 h or a serum creatinine concentration of more than 4.0 mg/dl at the start of hemofiltration related to poor prognosis. In view of these results, hemofiltration for refractory heart failure should be started earlier and performed carefully in order to avoid arrhythmia, cardiogenic shock, and other complications.

Since 1982 eight patients under 1 year of age with end-stage renal failure have been treated by chronic peritoneal dialysis (CPD) following insertion of an abdominal Tenckhoff catheter. We routinely perform a partial omentectomy now, and in males undertake bilateral exploration of the groins at the time of catheter insertion, with herniotomy or ligation of the patent processus vaginalis as required. Up to January 1990, 19 straight double-cuff catheters had been inserted with a total follow-up of 244.5 patient months. The median age at the initial catheter insertion was 14.6 weeks (range, 2 days to 11 months) and the median weight was 3.89 kg (range, 2.2 to 5.5). Peritonitis was the most common complication, with 46 episodes, representing one episode of peritonitis per 5.3 patient months on dialysis. The frequency of peritonitis has decreased in the last 6 months since all patients have been dialysed by two caregivers. The present rate of peritonitis is 1 episode per 10 patient months on dialysis. One patient has died of septicemia secondary to associated congenital abnormalities, one patient has regained renal function, and two patients have been transplanted, one successfully. Five patients are currently dialysing via their abdominal Tenckhoff catheters and awaiting transplantation. We conclude that neonates and infants under 1 year of age can be treated satisfactorily by CPD to enable successful preparation for transplantation later in childhood.

1182 patients were prospectively studied in order to evaluate the surgical risk factors. Stepwise regression logistic procedure was employed for statistical analysis. Postoperative complications included death, cardiac, respiratory, hepatic and renal failure, wound infection and sepsis. Various preoperative conditions were associated with postoperative complications but some of them, as malnutrition or operations prolonged over two hours, occurred more frequently. Age did not appear as a major risk factor. The determination of surgical risk is a major problem in general surgical practice and many attempts have been realized in order to predict postoperative outcome. Clinical judgment is still nowadays fundamental but predictive scores based on statistical analysis have proved to be valid and useful tools. The authors underline the importance of surgical risk prediction in therapeutic programming, especially in the aged and in cancer patient. The surgical or non surgical option and the type of operation to be performed result from a careful evaluation of operative risk and expectancy and quality of life.

The reported clinical use of the Sarns centrifugal pump (Sarns, Inc./3M, Ann Arbor, Mich.) as a cardiac assist device for postcardiotomy ventricular failure is limited. During a 25-month period ending November 1988, we used 40 Sarns centrifugal pumps as univentricular or biventricular cardiac assist devices in 27 patients who could not be weaned from cardiopulmonary bypass despite maximal pharmacologic and intraaortic balloon support. Eighteen men and nine women with a mean age of 60.4 years (28 to 83) required assistance. Left ventricular assist alone was used in 12 patients, right ventricular assist in 2, and biventricular assist in 13. The duration of assist ranged from 2 to 434 hours (median 45). Centrifugal assist was successful in weaning 100% of the patients. Ten of 27 patients (37%) improved hemodynamically, allowing removal of the device(s), and 5 of 27 (18.5%) survived hospitalization. Survival of patients requiring left ventricular assist only was 33.3% (4/12). Complications were common and included renal failure, hemorrhage, coagulopathy, ventricular arrhythmias, sepsis, cerebrovascular accident, and wound infection. During 3560 centrifugal pump hours, no pump thrombosis was observed. The Sarns centrifugal pump is an effective assist device when used to salvage patients who otherwise cannot be weaned from cardiopulmonary bypass. Statistical analysis of preoperative patient characteristics, operative risk factors, and postoperative complications failed to predict which patients would be weaned from cardiac assist or which would survive.
