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.

Although percutaneous transhepatic biliary drainage (PTBD) restores hepatic and renal function in patients with obstructive jaundice, it is not certain whether it reduces the rate of complications and death after biliopancreatic surgery. We studied the possibility that the operative risks of jaundiced patients are related to malnutrition and the usefulness of hyperalimentation with PTBD to reduce the incidence of complications. Sixty-four patients with obstructive jaundice and serum bilirubin greater than 200 mumol/l were randomized into two treatment groups (n = 32) with PTBD or PTBD + hyperalimentation. Four patients were withdrawn from the latter group, two for metastatic cancer and two for complications of PTBD. Before starting hyperalimentation, the incidence of malnutrition was assessed by biochemical, immunological and anthropometric tests: malnutrition was found in 70 per cent of the patients. All the patients had good recovery of hepatic function but patients treated with PTBD alone still had high mortality (12.5 per cent) and morbidity (46.8 per cent) after biliopancreatic surgery. When hyperalimentation was provided to patients on PTBD for a period of 20 days before the operation, the incidence of complications fell to 17.8 per cent and mortality to 3.5 per cent. These results suggest that the combined use of PTBD and hyperalimentation, improving both hepatic function tests and the nutritional status of jaundiced patients, can reduce the rate of complications after biliary and pancreatic surgery.

Vascular access devices that are completely implanted have been used for treatment of cancer patients. Vascular access devices are useful for transarterial infusion of anticancer drugs, intravenous hyperalimentation, and drainage of bile juice in obstructive jaundice. These systems have several advantages in the care of patients: they are sealed, they have no external tubes, and they may be useful for blood or biliary sample and intravenous hyperalimentation or chemotherapy. There are only minimal discomforts related to the implantation procedure and no need for routine external catheter care. Most importantly, the quality of the patient's life is dramatically improved without external tubes. For these reasons, we believe that vascular access devices should be indicated for patients with malignant tumors as much as placement of these devices is technically feasible.

Cholestatic jaundice is the major complication of total parenteral nutrition (TPN). Both the intravenous (IV) route of nutrition and the enteral fast have been implicated as causes of TPN-associated cholestasis (TPN-AC). The purpose of this study was to determine whether TPN-AC is caused by the TPN solution itself or the IV route of administration and enteral fast. Prepubescent rabbits (n = 24) were divided into four groups: CONTROL, fed standard lab chow; TPN, received a standard hyperalimentation solution of dextrose, Aminosyn, and lipids via the jugular vein; ENT, received the same hyperalimentation solution via a duodenostomy tube; and OSM, received a polymeric formula (Osmolite) via a duodenostomy tube. After 14 days on these diets, we measured bile flow, bile acid excretion, sulfobromophthalein (BSP) excretion, plasma amino acid profile, serum liver enzymes, and liver histology. Statistical analysis was by analysis of variance. Hyperalimentation solution significantly depressed hepatobiliary function, whether it was given IV or by gut. Bile flow in both the TPN (36.4 microL/kg/min) and ENT (46.2) groups was significantly less than CONTROL (84.5) or OSM (62.9). Hepatic secretory function, measured by excretion of the cholephilic dye BSP, was depressed in both TPN and ENT (57% and 55% of IV dose excreted in bile over 60 minutes, respectively) compared with CONTROL (84%) or OSM (71%). Serum liver enzymes were normal in all groups. Histological injury similar to TPN-AC in humans (portal inflammation and hepatocyte degeneration) was seen in both groups receiving the hyperalimentation solution.(ABSTRACT TRUNCATED AT 250 WORDS)
