The conventional animal model of human portal systemic encephalopathy is the dog with Eck fistula. Dogs fed standard dog chow after Eck fistula manifest anorexia, weight loss, hepatic atrophy and encephalopathy. This study was done to determine the natural history of dogs undergoing Eck fistulas when adequate nutrition is maintained with a palatable diet. Twenty-four mongrel dogs were divided into four groups--Eck fistula fed standard dry dog chow (EF-SC) (n equals nine); sham operated fed standard chow (SO-SC) (n equals five); Eck fistula fed a liquid (Isocal) diet (EF-LD), LD), and sham operated fed a liquid diet (SO-LD) (n equals five). Dogs were sacrificed when they had clinical signs of encephalopathy or up to 120 days after operation. EF-SC dogs had a daily caloric intake approximately 40 per cent of that of the other groups. Two EF-SC dogs died of sepsis within two weeks of the operation, the other seven became encephalopathic between 46 and 91 days (a mean of 63.6 +/- 15.6). No other dogs had signs of neurologic deterioration. EF-SC dogs lost 19 +/- 9 per cent body weight and the serum albumin level decreased 14.5 per cent while the other groups maintained body weight and serum albumin levels. Both EF-SC and EF-LD groups had decreased liver weight to body weight ratios (LW X 100/BW) compared with sham operated upon dogs reflecting hepatic atrophy (1.97 +/- 0.7 and 2.2 +/- 0.23 versus 3.04 +/- 0.85 and 3.48 +/- 0.44). Results of histologic examination of the liver revealed hepatocyte atrophy, deglycogenation and lipid accumulation in EF dogs. We conclude from these data that providing dogs with Eck fistula a palatable diet prevents weight loss and malnutrition, but not hepatic atrophy. The lack of neurologic signs in well nourished dogs suggests to us that data concerning hepatic coma from the standard Eck fistula model should be interpreted with extreme caution.

Peritoneovenous shunts (PVSs) have provided salutary effects on medically recalcitrant ascites, functional renal impairment, nutritional derangements, ventilatory embarrassment, and locomotion potential in patients with cirrhosis. While the LeVeen (LPVS) and Denver (DPVS) PVSs are most frequently implanted in such patients, postoperative complications of bleeding gastroesophageal varices, sepsis, and shunt occlusion occur with notable frequency. Addressing primarily the complication of PVS occlusion, a randomized prospective trial of LPVSs and DPVSs was conducted in cirrhotic patients with refractory ascites. From July 1, 1982 to July 1, 1984, 26 initial PVSs were implanted for hepatic-related intractable ascites. Twenty-two patients were eligible for randomization (cirrhosis, sterile ascites, initial PVS, total bilirubin level less than or equal to 6.0 mg/dL, prothrombin time less than or equal to 5-s prolongation, serum creatinine level less than or equal to 2.0 mg/dL [creatinine clearance rate greater than or equal to 20 mL/min], absence of recent [less than 30 days] bleeding gastroesophageal varices, or absent spontaneous encephalopathy). Twelve LPVSs and ten DPVSs were implanted; however, one patient with a DPVS was found to have hepatic polycystic disease and was excluded from analysis. All patients were followed up until death or Jan 1, 1985. The PVS patency determinations included contrast shuntography, technetium Tc 99m albumin scintigraphy, sequential manual compression (DPVS), and operative or autopsy observation. Using the Kaplan-Meier actuarial analysis, the LPVS patency proved to be highly superior to that of the DPVS, while survival was not significantly different. As LPVS and DPVS complications other than patency are comparable, the LPVS is preferred for its superior patency in cirrhotic patients with intractable ascites.

Twelve fatal cases of encephalopathy associated with sepsis were examined in a ten-year retrospective study. The sources of infection and organisms isolated were variable. Six of the patients had focal neurologic signs; five had seizures. The level of consciousness varied from drowsiness to deep coma, and electroencephalograms revealed diffuse or multifocal abnormalities. Computed tomographic head scans and cerebrospinal fluid examinations were usually unremarkable. Eight patients had disseminated microabscesses in the brain at autopsy. Four patients had proliferation of astrocytes and microglia in the cerebral cortex, a feature associated with metabolic encephalopathies. Additional findings included cerebral infarcts, brain purpura, multiple small white matter hemorrhages, and central pontine myelinolysis. Although sepsis may cause encephalopathy by producing disturbances in cerebral synaptic transmission and cerebral energy production through a toxic mechanism, bacterial invasion of the brain with the formation of disseminated microabscesses is also an important cause.

Eleven patients with familial hemophagocytic lymphohistiocytosis (FHLH) are described. They all belonged to four Jewish families of Iranian and Iraqi origin. Parental consanguinity was found in three families. The age of onset of disease ranged from 6 weeks to 36 months. All patients had fever, wasting, and enlargement of the liver and spleen. In addition, lymph-node enlargement and neurologic complications were common. The most consistent laboratory findings were pancytopenia, atypical lymphomonocytoid cells in the peripheral blood, abnormal liver function test results, and increased cerebrospinal fluid protein. The course was fatal in all patients. Nine of the 11 patients died within 2 weeks to 3 months of presentation, and 2 patients achieved temporary remissions but died of disease within 8 and 24 months, respectively. Response to antibiotic therapy or to the administration of corticosteroids and cytotoxic drugs was unimpressive. Pancytopenia complicated by sepsis or bleeding, hepatic failure, or encephalopathy were the terminal events. This report draws attention to the existence of FHLH in Jews of Iranian-Iraqi origin in whom parental consanguinity is very common.

Of 26 patients who underwent distal splenorenal shunting 4 or more years ago (1969 to 1978), 10 died 3 to 87 months postoperatively (mean 38.5 months). Six deaths were due to liver failure, two to hemorrhagic peptic ulcer disease (the shunt remained patent in each patient), one to brain hemorrhage, and one to sepsis. Eight of the surviving patients resumed professional activity, one showed transient signs of encephalopathy, one had a single episode of recurrent variceal bleeding that could be managed conservatively, and no patient had ascites. Eight patients were investigated angiographically and endoscopically. Preoperative and postoperative measurements of the portal vein showed a decreased diameter in five patients and no opacification in the other three 29 to 97 months after surgery. At endoscopy four patients had small residual esophageal varices, one patient had none, and the other three had large varicosities with variceal pressures between 30 and 40 cm H2O in two and above 40 cm H2O in one. Although the incidence of postoperative encephalopathy and variceal bleeding was low after distal splenorenal shunting, the operation did not prevent a decrease in hepatopetal portal flow and did not always abolish the esophageal varices.

Forty-five patients had operative disconnections of portoazygos venous collaterals for variceal hemorrhage. Nineteen alcoholic patients had urgent partial azygos disconnection (PAD) to control bleeding; this involved intragastric variceal and coronary and distal gastric-vein ligation. A complete azygos disconnection (CAD), which also included splenectomy, was done urgently in 14 patients and electively in 12 patients; 15 were alcoholics. All patients were assessed for operative risk by a modified Child's classification. Hospital mortality after urgent PAD or CAD in alcoholics was 67%, largely due to intraperitoneal sepsis or hepatorenal failure with recurrent hemorrhage. Operative modified Child's classification of survivors was better (lower) than in nonsurvivors. Eleven nonalcoholic patients had CAD; two died of intraperitoneal sepsis. Nine survivors did not rebleed nor have encephalopathy develop during an average follow-up of 41 months. Complete azygos disconnection was a good alternative, particularly in the elective setting, for patients with nonalcoholic portal hypertension.

A prospective study of 54 infants with birth weights of 1,000 gm or less was conducted over a period of two years. Of the 26 infants who survived, 24 weighed between 750 and 1,000 gm; two infants died after discharge and one was lost to follow-up, leaving 23 in whom serial observations were made over 18 months to 3 years of age. The incidence of neurologic deficit in these infants was 17% and of intellectual deficit, 13%. Of the four who were abnormal neurologically, two had spastic quadriparesis, one static encephalopathy, and one hydrocephalus secondary to intraventricular hemorrhage. The three with intellectual deficit had a developmental quotient less than 85. Of the perinatal factors examined, only birth asphyxia correlated significantly with both neonatal mortality and subsequent morbidity. Six (26%) of the surviving infants had mild, nonblinding retrolental fibroplasia; only one of them had a significant refractive error that required corrective lenses for vision. Sepsis was a significant contributor to neonatal mortality in ten of 28 infants who died, but was detected in only one survivor. Although the prognosis for the infant weighing 1,000 gm or less at delivery has improved significantly, there is promise for still further improvement by reducing perinatal asphyxia.

The authors examined 23 brains of female patients who died during pregnancy or after delivery. Four clinical groups were distinguished: 1. sepsis, 2. gestosis, 3. patients with cardiac diseases, 4. other cases of death. General autopsy on all the dead patients was performed. Macroscopically the brain revealed the signs of oedema and herniationes. Microscopic findings showed in the sepsis and gestosis groups, distinct changes in small blood vessels. Their walls were often statified and impregnated with fibrin. In the cases with the DIC syndrome microthrombosis could be seen. Only in 2 patients cerebral arterial occlusion was noted. Neurons revealed the secondary changes described as anoxic encephalopathy.

Six cirrhotic patients underwent emergency esophageal transection utilizing the EEA Auto Suture stapling instrument for treatment of unrelenting variceal hemorrhage. All were grade C, and the combination of ascites, encephalopathy, and jaundice was present in four. All were critically ill with ancillary medical problems, including recent subtotal gastrectomy with sepsis and dehiscence, coexisting malignant biliary obstruction, and respiratory insufficiency. All were anergic to skin testing. Four died in the postoperative period, primarily of problems related to sepsis and ascites present before operation. Autopsy showed a well-healed anastomosis without stricture and complete interruption of the varices in all. No patient had recurrent bleeding. All received oral or tube feedings after operation. Two survive at 2 and 1.5 years with no recurrence of varices. This is a rapid, simple, and effective technique which can be done with minimal blood loss or training. There is no diversion of portal blood and minimal interruption of collateral circulation. Whereas the long-term benefits in terms of rebleeding are not yet known, results to date suggest a trial earlier and in better risk patients as a definitive treatment procedure.

Sixteen patients underwent a modification of the Sugiura procedure for bleeding esophageal varices, involving (a) esophageal transection, (b) splenectomy, (c) selective vagotomy, and (d) pyloroplasty. Five patients died, and the remaining 11 had barium studies of the esophagus and stomach which were compared with the preoperative appearance. Esophageal varices disappeared in 7 patients and persisted in 1. No recurrent bleeding or encephalopathy was seen: however, there were a large number of complications, including pleural effusion, ascites, ileus, pneumonia, and renal failure. Hepatic failure, respiratory failure, and sepsis secondary to gastrointestinal leakage also occurred and were fatal in all cases. As the Sugiura procedure is increasingly being employed in the United States, radiologists should be familiar with the spectrum of postoperative radiographic findings in the esophagus and stomach.
