Surgical treatment has been used in those patients with hemorrhagic pancreatitis who deteriorate after several days of intensive medical therapy, or in those patients in whom the diagnosis cannot be established early in the course of treatment. Initial therapy consisted of: cholecystostomy or T-tube drainage in those patients who have gallstones, jaundice, or distended biliary tree; gastrostomy for prolonged gastric decompression; jejunostomy to provide a portal for enteroalimentation; and appropriate soft rubber drainage of the pancreatic bed as a simple, safe, and effective means of treating severe hemorrhagic pancreatitis. Adjunctive daily hyperalimentation and later sequestrectomy of necrotic pancreatic tissue provided a mortality of 20 per cent and complete rehabilitation of sixteen of thirty patients so treated. Delaying the initial approach to necrotic pancreas allows precise delineation of necrotic material so that sequestrectomy, leaving behind normal pancreas, can be carried out to avoid exocrine and endocrine deficiencies after the acute episode has passed.

Initially, diarrhea is almost universal but becomes self-limited unless the patient persists in overeating. Weight loss averages 75 to 100 lb the first year, with a stable level generally achieved after 18 months. Among the serious potential complications are enteritis, kidney stones, gallstones, and hepatopathology. Some can be anticipated and kept at bay by prophylactic measures like high-protein intake.

Cholelithiasis in infants is rare, and has usually been associated with hemolysis, ileal disease, congenital anomalies of the biliary tree, hyperalimentation, and prolonged fasting. With the increased use of abdominal ultrasonography (US), more cases of cholelithiasis are being discovered. We report our experience with 13 infants diagnosed on abdominal US to have gallstones. There were 9 boys and 4 girls with an average age at diagnosis of 2.6 months (range, 0 to 9 months). Predisposing factors could be identified in only 6 of the 13 patients. Two patients with obstructive jaundice underwent cholecystectomy and common bile duct exploration. One patient with choledocolithiasis and common bile duct dilatation was observed. His stone passed spontaneously, with resolution of symptoms. Ten patients without cholestasis remained asymptomatic, with disappearance of lithiasis in five of them. Neonatal cholelithiasis is more common than previously suspected; it seems to affect males more often than females and is usually not associated with known predisposing factors. It appears to be a temporary, self-limiting phenomenon, and an aggressive approach is not warranted in the asymptomatic infant. Surgical or radiological intervention should be reserved for the symptomatic patients or those with underlying lithogenic disorders.

Biliary sludge formation is reported to be one of the complications of intravenous hyperalimentation (IVH); however, the change in human biliary lithogenicity during IVH treatment has been little studied. To clarify the pathogenesis of IVH-induced biliary sludge, we determined biliary lipid composition, vesicular cholesterol concentration, and nucleation time using gallbladder bile samples collected from three groups: The IVH group comprised 9 patients who received IVH with fasting for a period of 2-8 days prior to surgery for gastrointestinal diseases. The control group comprised 10 patients operated after overnight fasting for gastrointestinal diseases. The cholesterol gallstone group comprised 14 patients surgically treated for cholesterol gallstone disease after overnight fasting. The nucleation time in the IVH group was significantly shorter (7.8 +/- 5.3 days, mean +/- SD) than that in the control group (17.3 +/- 5.5 days), while it did not reach the value in the cholesterol gallstone group (3.1 +/- 3.3 days). The cholesterol saturation index in the IVH group (1.01 +/- 0.27) was higher but not significantly different compared with the control group (0.80 +/- 0.21). The concentrations of biliary lipids and individual bile acid were similar in the IVH and control groups. The vesicular cholesterol concentration in the IVH group (3.0 +/- 2.1 mM) was significantly higher than that in the control group (0.9 +/- 1.0 mM). In conclusion, IVH with fasting causes a rapid cholesterol nucleation time and a higher vesicular cholesterol concentration, thereby inducing an initial stage of gallbladder sludge formation.

In a prospective trial to determine whether gastric surgery induces gallbladder sludge and stone formation, 48 patients with gastric cancer were ultrasonographically examined with simultaneous observation on changes in gallbladder contractile function before and serially for 5 years after gastrectomy. Gallbladder sludge formation was induced with a high frequency of 42% 1 month after gastrectomy, with corresponding significant lowering of gallbladder contractile function. Most of gallbladder sludges, however, disappeared within 12 months in relation to the gradual recovery of gallbladder contractile function. Conversely, gallstone developed in nine patients (18.8%), mostly more than 6 months after gastrectomy. Interestingly, gallstone formation was induced in seven patients who were sludge negative. An evolvement of gallbladder sludge into stone was observed in only two patients, who were, however, treated with intravenous hyperalimentation. This study first provides evidence for the relationship between gastrectomy and a considerably high frequency of incidence of gallbladder sludge and stone in relation to changes in gallbladder kinetics after gastrectomy.

Common variable hypogammaglobulinemia (immunodeficiency), a disorder characterized by late-onset immunoglobulin deficiency and lack of humoral immunity, has a variable association with bronchiectasis, cholelithiasis, nodular lymphoid hyperplasia, gastrointestinal neoplasia, megaloblastic anemia, and malabsorption. The patient described in this report had all of the above except neoplasia. In addition, he had calcium oxalate renal stones probably secondary to his malabsorption. The first case demonstrating the beneficial effect of home hyperalimentation in patients with severe malabsorption refractory to other treatments is described. Home hyperalimentation overnight allows the patient freedom for daily activities while also being more cost-effective than in-hospital parenteral nutrition.

Normal and alloxan-diabetic male mice (Crj-ICR) were fed a diet containing 0.5% cholesterol for 5 and 10 weeks, and gallbladder bile was analyzed for cholesterol, phospholipids and bile acids, feces for sterols and bile acids, and plasma and liver for cholesterol, phospholipids, and triglycerides. Normal mice developed no gallstones but the diabetic mice developed cholesterol gallstones with an incidence of 70% by 5 weeks and 80% by 10 weeks after feeding of the cholesterol diet. Diabetic mice fed the ordinary diet also developed stones (23%) by 10 weeks. In the diabetic mice, the gallbladder was enlarged about threefold, and biliary lipid concentration, diet intake, and fecal excretion of sterols and bile acids increased but body weight decreased. Cholic acid and beta-muricholic acid comprised over 40% each of the total biliary bile acids in normal mice, but cholic acid increased to about 80% and beta-muricholic acid decreased to a few percent in the diabetic mice. Fecal excretion of bile acids increased after cholesterol feeding in both normal and diabetic mice, but the increased bile acid in the normal animals was beta-muricholic acid and that in the diabetic mice was deoxycholic acid. The mice that developed gallstones showed a marked increase in biliary cholesterol value and decreases in gallbladder bile and bile acid concentration, but no difference in biliary and fecal bile acid composition, bile acid synthesis, fecal sterols, or plasma and liver lipid levels. Cholesterol absorption was increased in the diabetic mice when examined by plasma 14C/3H ratio and fecal 14C-labeled sterol excretion after a single oral administration of [14C]cholesterol and a simultaneous intravenous injection of [3H]cholesterol. These data led to the conclusion that cholesterol gallstones developed in alloxan-diabetic mice fed excess cholesterol, due to the hyperphagia and the enhancement of cholesterol absorption caused by increases in the synthesis and secretion of cholic acid.

Patients who receive hyperalimentation undergo prolonged periods of fasting which may alter bile composition and lead to gallbladder stasis, both important factors in gallstone formation. Therefore, we tested the hypothesis that patients who receive long-term TPN are at increased risk for cholelithiasis by performing cholecystosonography on adult patients who had received a minimum of 3 months of intravenous hyperalimentation during 1981. Seventy-one patients whose mean age was 41.9 years, 41 percent of whom were men, met these criteria. Gallstones had been diagnosed in 11 of the 71 patients (15 percent) before the initiation of parenteral nutrition. Twenty-one of the remaining 60 at risk patients (35 percent) were discovered to have cholelithiasis after hyperalimentation was started. The 45 percent prevalence of gallstones in our 71 patients was significantly higher (p less than 0.001) than predicted from autopsy data. In addition, the 49 percent prevalence of cholelithiasis in our 53 patients with ileal disorders was significantly greater (p less than 0.02) than predicted from a study of patients with similarly defined ileal disorders. This analysis strongly suggests that patients who receive long-term TPN are at increased risk for the development of cholelithiasis.

A review of the literature on the medical and nutritional use of medium-chain triglycerides (MCTs) since 1970 is presented with additional discussions on the various modifications and applications of the MCTs in the synthesis of certain structured lipids. The metabolism of MCTs in the liver and extrahepatic tissues is discussed along with further documentation of the use of MCTs in malabsorption and hyperlipidemia cases. Recent applications of MCTs and modified MCTs in hyperalimentation, deficiency in the carnitine system, epilepsy, obesity, and other special areas of application are cited. The use of medium-chain monodiglycerides for dissolving cholesterol gallstones is presented. The contraindications for the use of MCTs in ketosis, acidosis, and cirrhosis are also discussed. Suggestions for use of MCTs in a variety of medical and nutritional applications are presented.

Torulopsis glabrata, a fungus commensal with the human gastrointestinal tract, so far has not been recognized as a cause of pancreatic sepsis. We report the cases of two patients with pancreatic pseudocysts that became infected with T. glabrata. A 20-year-old woman 6 weeks postpartum had acute gallstone pancreatitis complicated by pseudocyst formation and pancreatic sepsis. Pseudocyst fluid obtained at cystogastrostomy showed a pure culture of T. glabrata. A 52-year-old man with multiple medical problems showed signs of an infected pseudocyst 9 days after he was hospitalized for alcoholic pancreatitis. Computed tomography (CT)-guided aspiration of the the pseudocyst fluid confirmed T.glabrata as the infecting organism. Neither patient had a history of endoscopic or surgical manipulation. Prolonged therapy with broad-spectrum antibiotics and parenteral hyperalimentation were implicated as risk factors, and other possible pathogenic mechanisms were considered. Both patients were treated successfully with a combination of percutaneous or surgical drainage and amphotericin B, which appears to be the most active drug in vitro. The efficacy of other antifungal agents is discussed. In the context of pancreatitis and/or pseudocysts, empiric therapy with broad-spectrum antibiotics should be minimized because it predisposes patients to superinfection by opportunistic pathogens.
