A prospective study of choledocholithiasis was performed using 110 patients with presumptive diagnoses of acute gallstone pancreatitis. The incidence of migrating and persistent bile duct stones was determined using stool screening and intraoperative cholangiography, and the clinical significance of continued stone obstruction of the papilla was investigated using ultrasound assessment of migration time and a second evaluation of prognostic signs. Pancreatic inflammation was confirmed at surgery in 51 patients, of whom only 27 had stones in the stools (n = 22) or the bile duct (n = 5), suggesting that choledocholithiasis may not be the sole triggering factor of acute gallstone pancreatitis. Neither delayed migration nor persistent stone obstruction of the papilla promoted pancreatic inflammation.

Surgery, in particular laparoscopic cholecystectomy, will probably remain the preferred treatment for symptomatic gallbladder stones. It is unlikely that other methods of treatment, such as oral dissolution therapy or lithotripsy, can match the results and patient acceptance of this procedure. With the advent of laparoscopic cholecystectomy, however, more patients with choledocholithiasis will undergo endoscopic sphincterotomy and endoscopic common bile duct clearance. This may change, however, if the common bile duct can be explored safely through the laparoscope. Finally, severe gallstone pancreatitis will continue to be treated by early endoscopic sphincterotomy followed by cholecystectomy. Nevertheless, endoscopic sphincterotomy alone will be used more often as a definitive treatment to prevent recurrent attacks, especially in elderly patients who are poor candidates for cholecystectomy.

Since the introduction of endoscopic sphincterotomy approximately 15 years ago, the indications for this procedure have expanded. Currently endoscopic sphincterotomy is the procedure of choice for management of retained common bile duct stones following cholecystectomy. It is also being used more frequently for choledocholithiasis with an intact gallbladder in high-risk patients and in some patients with acute gallstone pancreatitis. In patients recovering from an episode of gallstone pancreatitis, standard practice has been subsequent cholecystectomy with possible exploration of the common bile duct. To avoid surgery in high-risk patients, we propose that an elective endoscopic sphincterotomy may be a reasonable therapeutic option regardless of whether common bile duct stones are present at the time of ERCP. A prospective trial is needed to examine this issue since to date there is no literature on endoscopic sphincterotomy in the absence of choledocholithiasis for gallstone pancreatitis in patients with intact gallbladders.

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.

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 treatment of choice for most retained bile duct stones is by nonoperative means. If a T-tube is in place, percutaneous techniques via the T-tract are indicated. Percutaneous access via puncture of a Roux-en-Y loop is also practical. In the absence of a T-tube, retrograde endoscopic techniques should be used. Both techniques are very effective and safe. Stones in the intrahepatic and extrahepatic ducts also can be treated nonoperatively. Endoscopic sphincterotomy has a role in the treatment of selected patients with gallstone pancreatitis, acute cholangitis, and choledocholithiasis with in situ gallbladders. In difficult cases, endoscopic and percutaneous techniques are employed in combination.

Endoscopic treatment of bile duct stones has reached a high degree of perfection by the introduction of adjuvant therapies raising the rate of success while at the same time reducing risk. Large stones are fragmented mechanically or by means of extracorporal shock wave lithotripsy thus permitting to avoid a long and risky papillotomy. Drainage of the bile is assured with a nasobiliary drain in case of primary failure reducing the risk for cholangitis. Endoscopic treatment is the choice for residual or recurring stones after cholecystectomy and for severe purulent cholangitis in which surgical treatment is still charged with a high mortality. Endoscopic stone removal is further indicated when an operation per se carries a high risk. Long-term studies have demonstrated that even patients in which the gall bladder is preserved stay free of recurrence. In patients with severe biliary pancreatitis early papillotomy reduces complication-rate and mortality. The question remains unsettled whether patients at normal risk with simultaneous cholecysto- and choledocholithiasis should undergo direct cholecystectomy and bile duct revision or if they could profit from endoscopic removal of stones prior to cholecystectomy.

We performed endoscopic retrograde cholangiopancreatogram (ERCP) on 200 patients over a four and a half year period. The duct of interest was successfully cannulated in 173 cases (87%). The most common indications were obstructive jaundice, cholangitis, chronic upper abdominal pain and suspected pancreatic disease. The commonest findings were cholelithiasis and malignant strictures of the common bile duct (CBD). Forty seven patients (27%) had normal examinations. Sixty-two of 87 (71%) patients with choledocholithiasis underwent endoscopic sphincterotomy (ES). The success rate for active stone extraction was 82% (27/33) while 64% (14/22) of patients managed expectantly cleared their CBD stones spontaneously after ES. The immediate complication rate of ES was 13% and included pancreatitis, stone impaction, cholangitis and bleeding. There was no complications amongst patients who underwent ERCP alone and no mortality in this series. Twenty three patients (26%) with choledocholithiasis proceeded to surgery because the stones were considered too large to remove endoscopically. One patient had endoscopic stone removal without prior ES while another had a permanent stent inserted for drainage. We conclude that ERCP and ES are useful and safe modalities in the assessment of biliary tract diseases and the treatment of choledocholithiasis.

The authors had 158 patients with acute block of the terminal part of the choledochus under observation. According to the clinical course, a biliary, pancreatic, and mixed forms were distinguished. The emergency diagnostic program was made up of ultrasonic examination, esophagogastroduodenoscopy, ERCP, and laparoscopy. The cause of the block of the terminal choledochus was choledocholithiasis in 104 patients, papillitis and microcholedocholithiasis in 36, and ++choledocholithiasis and stenosis of the major duodenal papilla in 18 patients. Acute block of the major duodenal papilla was found in 76 and acute block of the intramural part of the choledochus in 76 patients. The mixed form prevailed in the first and the biliary form of hypertension in the second. Operations (cholecystectomy, choledocholithotomy with external or internal drainage of the choledochus) were performed on 42 patients, the postoperative fatality rate was 9.7%. Emergency EPST and extraction of concrements was undertaken in 116 patients. Increase in the clinical picture of acute cholecystitis and destructive pancreatitis after EPST called for operative interventions on 21 patients. The lethality rate after EPST performed for acute block of the terminal choledochus was 6.1%.

We reviewed 574 endoscopic sphincterotomy procedures. Fifty-six precut papillotomies were performed. Presenting conditions included choledocholithiasis, cholangitis, benign and malignant papillary strictures, and stenosing papillitis. Complications were identified in 16 percent: perforation in 9 percent, pancreatitis in 5 percent, bleeding in 2 percent, and pancreatic abscess in 2 percent. One patient died. Six patients required operation for complications. Perforation of the duodenum or common bile duct seen within 8 hours was managed with drainage and closure of the perforation with minimal complications. Duodenal perforations operated on later than 8 hours required more extensive procedures. All these patients had significant post-operative complications. Three patients were managed nonoperatively. Precut papillotomy carries a significantly higher complication rate than conventional sphincterotomy. Our experience suggests that there is no place for conservative management of duodenal perforation.
