Alcoholic liver disease includes steatosis, alcoholic hepatitis and cirrhosis. Other liver diseases of genetic origin, but with a curious association with alcohol intake, are hemochromatosis and porphyria cutanea tarda. The attribution of chronic hepatitis to alcohol intake remains speculative, and the association may reflect hepatitis C infection. Hepatic injury attributed to alcohol includes the changes reported in the fetal alcohol syndrome. Steatosis, the characteristic consequence of excess alcohol intake, is usually macrovesicular and rarely microvesicular. Acute intrahepatic
cholestasis
, which in rare instances accompanies steatosis, must be distinguished from other causes of intrahepatic
cholestasis
(e.g., drug-induced) and from mechanical obstruction of the intrahepatic bile ducts (e.g.,
pancreatitis
, choledocholithiasis) before being accepted. Alcoholic hepatitis (steatonecrosis) is characterized by a constellation of lesions: steatosis, Mallory bodies (with or without a neutrophilic inflammatory response), megamitochondria, occlusive lesions of terminal hepatic venules, and a lattice-like pattern of pericellular fibrosis. All these lesions mainly affect zone 3 of the hepatic acinus. Other changes, observed at the ultrastructural level, are of importance in progression of the disease. They include widespread cytoplasmic shedding, and capillarization and defenestration of sinusoids. Progressive fibrosis complicating alcoholic hepatitis eventually leads to cirrhosis that is typically micronodular but can evolve to a mixed or macronodular pattern. Hepatocellular carcinoma occurs in 5 to 15% of patients with alcoholic liver disease. The clinical syndrome of alcoholic liver disease is the result of three factors--parenchymal insufficiency, portal hypertension and the clinical consequences of extrahepatic damage produced by alcohol. At the several phases of the life history of alcoholic liver disease, the individual factors play a different role. The clinical manifestations of alcoholic steatosis are mainly extrahepatic in origin. Those of alcoholic hepatitis reflect mainly parenchymal insufficiency and those of cirrhosis are mainly those of portal hypertension. Alcoholic liver injury appears to be generated by the effects of ethanol metabolism and the toxic effects of acetaldehyde, perhaps the immune responses to alcohol- or acetaldehyde-altered proteins, and questionably enhanced by viral hepatitis. Alcoholic hepatitis may be mimicked histologically, and to a varying degree clinically, by a number of conditions (obesity, diabetes, several drug-induced injuries, jejunoileal bypass, and related "shortcircuiting" of the bowel). Perhaps the most important facet of the hepatotoxicity of alcohol is its enhancement of the effects of a number of other hepatotoxic agents, among which acetaminophen is the prime example.

The
cholestasis
and
pancreatitis
model was studied experimentally in 144 white rats. The influence of intraperitoneal injections of dalargin on the level of lipid peroxidation and on xanthine oxidase activity of the liver tissues in periods of 1, 3 and 5 hours was investigated. During that period the activity of hepato-specific enzymes in the liver tissues and serum were investigated. The reduction of xanthine oxidase activity in all the periods after injection of dalargin was discovered, the level of malonic dialdehyde was reduced by 43.8% 3 hours later. Simultaneously, the increase of the level of histidase in liver tissues was discovered (on 104.3% and 56.3% after 3 and 5 hours accordingly) and later the tendency to decrease the activity in serum was observed.

Forty-four elderly patients (mean age, 77.2 years; range, 65 to 95) with acute
bile duct obstruction
, with gallbladder in situ, underwent endoscopic sphincterotomy without subsequent cholecystectomy during the same hospitalization. Thirty patients had periampullary duodenal diverticula, and 14 had no diverticula. Because periampullary diverticula were associated with biliary and pancreatic complications, possibly as a result of stasis in the diverticula, the clinical course in patients with and without diverticula was compared. Endoscopic sphincterotomy was well tolerated and resulted in a rapid clinical improvement in all patients. There were four complications related to the procedure (
pancreatitis
, two, and cholangitis, two), all were treated conservatively, and there were no deaths. The clinical outcome was similar in both groups of patients. During a mean follow-up of 25 months (range, 6 to 58), only two patients (one of each group) underwent elective cholecystectomy 2 and 3 months after initial presentation. It is concluded that endoscopic sphincterotomy is a safe and effective alternative to surgery as an initial treatment in elderly patients with choledocholithiasis and gallbladder in situ. Periampullary duodenal diverticulum does not interfere with the favorable results of endoscopic sphincterotomy in patients with gallbladder in situ.

The Sump syndrome is an infrequent complication of a choledochoenterostomy (choledochoduodenostomy or choledochojejunostomy) performed for recurrent stone disease: a sump or pit develops at the retroduodenal section of the choledochus between the enterostomy and papilla where stones, lithogenic bile and gastrointestinal contents accumulate. This may lead to abdominal pain,
pancreatitis
and
cholestasis
and/or cholangitis when sludge obstructs the enterostomy. Surgical treatment has been replaced by endoscopic papillotomy. The major interest of this experience was that regarding migration of the stones to intestine, the spontaneous resolution could be documented in two patients; in other two cases, because of contraindications in one case and for refusing therapy in another, the stones still remain at the retroduodenal choledochus. In a follow up of two to eight years there is a favorable evolution without any surgical or endoscopic treatment of the papilla.

One hundred symptomatic patients with radiolucent gallbladder stones were treated with a new piezoelectric lithotripter and oral chemolitholytic agents. Stone disintegration was achieved in 99 of these patients (99%) with a mean (+/- SD) maximum fragment size of 5.1 +/- 4.1 mm. Significant differences were found when the mean (+/- SD) fragment sizes of single stones less than or equal to 20 mm (4.2 +/- 2.5 mm) were compared with those of single stones greater than 20 mm (5.8 +/- 3.4 mm; P less than 0.05) and multiple stones (6.2 +/- 3.8 mm; P less than 0.05), respectively. None of the patients required anesthesia, analgesics, or sedatives before or during the treatment. The stone-free rates for all patients followed up for up to 4-12 months (mean +/- SD, 10.7 +/- 2.9 months) were 18% (1 month), 25% (2 months), 38% (4 months), 52% (8 months), and 67% (12 months). Partly significant differences were obtained in stone-free rates for single stones (less than or equal to 20 mm) compared with larger stones (greater than 20 mm) and multiple stones (P less than 0.05), respectively. Serious adverse reactions (i.e.,
cholestasis
and
pancreatitis
) were observed in only 3 patients (3%). These conditions were induced by fragment impaction in the common bile duct. In 2 of these patients, endoscopic retrograde cholangiopancreatography with endoscopic sphincterotomy was required. It is concluded that piezoelectrically generated shock waves are suitable for the effective and safe disintegration of gallbladder stones in humans. The anesthesia-free and analgesia-free shock-wave application opens up the possibility to perform biliary lithotripsy as an outpatient procedure. The stone-free rate achieved in combination with oral bile acids is most promising for single stones (less than or equal to 20 mm).

In patients with chronic pancreatitis, common
bile duct obstruction
is reported in 3.2-45.6% of patients; however, only 5-10% of all patients with chronic pancreatitis require operative decompression of the bile duct. The cause of the intrapancreatic stricture of the common bile duct may be either a fibrotic inflammatory restriction, or compression by a pseudocyst. Obstruction of the duodenum is much less common than common
bile duct obstruction
in chronic pancreatitis occurring in less than 1-2% of patients with chronic pancreatitis. Colonic obstruction secondary to
pancreatitis
is very infrequent. The intrapancreatic strictures of chronic pancreatitis are characteristically smooth and tapering on endoscopic retrograde cholangiopancreatography (ERCP), but in some patients, they may have a sharp cut-off and closely resemble the appearance of carcinoma of the pancreas invading the bile duct. The natural history of these intrapancreatic strictures is variable. They may progress and be associated with cholangitis, biliary cirrhosis, common duct stones, or may remain stable for years or regress. Prior pancreaticojejunostomy is not protective against the development of intrapancreatic biliary strictures which may follow in 5-30% of patients, with most authors reporting an incidence of less than 10%. Evaluation of alkaline phosphatase, bilirubin, the presence of jaundice, or the appearance of an intrapancreatic stricture on ERCP is not predictive of whether cholangitis or biliary cirrhosis may or may not develop. The incidence of cholangitis and biliary cirrhosis in patients with intrapancreatic stricture is 9.4% and 7.3%, respectively. Laennec's cirrhosis occurs in a similar number of patients. Operation is indicated in patients with intrapancreatic strictures of the common bile duct in association with chronic pancreatitis in patients developing cholangitis, biliary cirrhosis, common duct stones, progression of the stricture, persistent high elevations of alkaline phosphatase and/or bilirubin for over a month or inability to rule out cancer of the pancreas or periampullary region. The operation of choice is choledochoduodenostomy or Roux-en-Y choledochojejunostomy to bypass the obstructed intrapancreatic portion of the common bile duct. Persistent duodenal obstruction for over 3 or 4 weeks is an indication for gastrojejunostomy. Pain is not a feature of common
bile duct obstruction
in the absence of cholangitis. In the presence of pain associated with chronic pancreatitis, longitudinal pancreaticojejunostomy is the operation of choice combined with Roux-en-Y choledochojejunostomy. Some of the newer operations, e.g., the Beger and Frey procedures, may make the necessity of a separate operation for biliary decompression superfluous.

During the past two decades, cholelithiasis has been recognized in increasing numbers of pediatric patients. This diagnosis should be considered in the event of upper abdominal complaints, particularly when one or more risk factors are evident. The etiology may be unknown or may be related to risk factors, including hemolytic conditions. In recent years, it has become evident that approximately 80% of gallstones in children are not due to hemolytic disease and that the remaining 20% are related to recurring hemolysis. The diagnosis of gallstones is best confirmed with ultrasonography. Routine ultrasonographic evaluation should be performed at intervals for all children who received TPA for more than 4 weeks, particularly those who have had ileal resection or have had chronic enteritis (Crohn disease). Cholecystectomy is the procedure of choice for symptomatic children with cholelithiasis, regardless of age. Cholecystectomy is recommended for the asymptomatic child younger than 3 years of age when echogenic shadows have been present for at least 12 months following resumption of oral feedings or when the gallstones are radiopaque. Also, cholecystectomy is advised for asymptomatic children who are older than 3 years of age if ultrasonographic studies confirm that echogenic foci with shadowing are true stones and not echogenic sludge. Complications of common
bile duct obstruction
,
pancreatitis
, perforation with bile peritonitis, and life-threatening sepsis may thus be prevented. Morbidity and mortality following cholecystectomy are expected to be relatively low in the pediatric age group.

Tumour-associated antigens CA 50 and CA 19-9 were determined in serum of 208 patients. Specificity of both neo-antigens as tumour markers was equally good, at 100% and 95%, in patients without malignancy or gastrointestinal disease, respectively, using an upper limit of normal of 17 U/ml for CA 50 and 37 U/ml for CA 19-9. Benign diseases of the upper gastrointestinal tract, such as
pancreatitis
,
cholestasis
or cirrhosis of the liver, reduce the specificity of CA 50 more than of CA 19-9. For example, specificity of CA 50 is only 33% for choledocholithiasis, but 74% with CA 19-9. The sensitivity of both closely related sialogangliosides in malignancies of the upper GI tract is similar, with the usual normal limits: in pancreas carcinoma 77% for CA 50, 81% for CA 19-9; in biliary tract carcinoma 80% for CA 50, 90% for CA 19-9; in gastric carcinoma 40% for CA 50, 50% for CA 19-9. But if one equalizes the upper limits of normal for both markers to a common 95% specificity, the tumour-indicating sensitivity of CA 19-9 clearly surpasses that of CA 50. Malignant tumours not recognized by increased levels of CA 19-9 also escape serological diagnosis with CA 50.

The case records 50 patients with abdominal pain and hyperamylasemia were studied in detail. Ten cases of gallstone induced hyperamylasemia, in which no evidence of
pancreatitis
was found at operation, were excluded. The etiological factors in the remaining group of forty cases of acute pancreatitis, in a community practicing alcohol abstinence, were reviewed. Both alcoholic and idiopathic
pancreatitis
were insignificant factors in the etiology of acute pancreatitis. Eighty percent of cases of acute pancreatitis were due to biliary tract disease. A younger age-group and female preponderance, as well as biochemical evidence of
cholestasis
, was observed in this group. An inverse relationship between preoperative serum amylase levels and the severity of the disease was noted. A more aggressive diagnostic work-up is, however, warranted to identify these cases, for which early surgery is advocated. There was no mortality in operated cases of biliary
pancreatitis
.

Twenty patients undergoing sphincteroplasty for cholelithiasis were randomly divided into two groups of 10. The former (T) were treated with a 4-h somatostatin intravenous drip (250 micrograms/h), started at the beginning of operation, while the latter (C) made up the control group. Serum and urine amylase, amylase creatinine clearance ratio, and liver function tests were assessed for 2 days before surgery, after the operation and for a period of 5 postoperative days. Homogeneity between the two series was verified in experimental conditions. Statistical differences occurred postoperatively in amylase creatinine clearance ratio, which proved higher in C group, and gamma-GT, which was higher in T group. Short-term somatostatin administration proved effective in reducing the postoperative amylase creatinine clearance ratio, although more evident results are reported after long-term administration.
Cholestasis
or any serious impairment in liver function did not occur, suggesting the suitability of somatostatin use even in patients with jaundice. Since a relationship between postoperative amylase levels and risk of
pancreatitis
has not yet been proved, the value of somatostatin in the prevention of postoperative
pancreatitis
after sphincteroplasty needs to be further verified.
