In a 15-month period, 110 patients with subsequently proved biliary dilatation were evaluated with ultrasound (US). The level of dilatation was defined as pancreatic, suprapancreatic, or at the level of the porta hepatis. Causes of dilatation included pancreatitis, choledocholithiasis, neoplasm, and stricture. The distal duct was examined initially on transverse scans obtained with the patient in a semierect right posterior oblique position; the proximal duct was then examined on longitudinal scans obtained with the patient in a supine left posterior oblique position. When this scanning technique was used, US indicated the level of dilatation in 91.8% of cases and suggested the correct cause in 70.9%. Because this approach markedly improves US visualization of the intrapancreatic bile duct, distal obstructing lesions, which are the most common, can be optimally examined.

The term "functional" as applied to disorders of the sphincter of Oddi is indefinite since it encompasses a spectrum of disorders from histopathologic fibrosis of the sphincter to sphincteric dysfunction without evident pathologic transformation. Although there are several approaches to the diagnosis of sphincter of Oddi dysfunction, the diagnosis still depends on the exclusion of other causes of obstruction. Reports of surgical sphincteroplasty in patients with this diagnosis suggest that the outcome is unpredictable. Operative mortality ranges from 0.6% to 6.0% and morbidity from 3.3% to 18%. Operative sphincteroplasty appears to have no adverse sequelae long-term, although there are few reports of extended follow-up. In our experience, about 10% of patients undergoing endoscopic sphincterotomy for calculi have recurrent biliary problems during extended follow-up, but most problems were not formidable. In large series of patients undergoing endoscopic sphincterotomy, papillary stenosis is the indication for the procedure in about 5% of cases. With this indication, immediate complications occur with greater frequency compared to endoscopic sphincterotomy for choledocholithiasis. The validity of every proposed test for sphincter dysfunction and/or stenosis has been challenged, and the diagnosis must still be considered imprecise. This fundamental problem makes it difficult to interpret the results of endoscopic sphincterotomy. It also necessitates a cautious approach to management of this disorder by endoscopic sphincterotomy. Other methods of sphincter manipulation such as endoscopic balloon dilation have not been studied extensively. Although endoscopic sphincterotomy has been performed in a few patients with idiopathic recurrent pancreatitis, the procedure must be considered experimental in this group of patients.

The factors influencing the migration of gall stones are ill understood. Altogether 331 patients undergoing cholecystectomy were studied prospectively. The diameters of the cystic and common bile ducts and of stones in the gall bladder and bile ducts were measured. Increasing pressure was applied to the freshly excised gall bladder in an attempt to evacuate stones through the cystic duct. Stones passed in 33 (60.0%) of patients with choledocholithiasis, 45 (67.2%) of patients with pancreatitis, and 7 (3.2%) of patients without either pancreatitis or choledocholithiasis. Stones migrated in 6 (3.0%) who had a normal cystic duct diameter (less than or equal to 4 mm) and in 46 (32.5%) with a duct over 4 mm diameter. Common bile duct stones were often larger than the diameter of the cystic duct and when reintroduced into the gall bladder would not migrate. The passage of debris (less than or equal to 1 mm) through the cystic duct bore no relation to the presence or absence of choledocholithiasis or a dilated cystic duct. Small stones (1-4 mm diameter) must migrate to initiate and facilitate further migration; some must increase in size in the common bile duct. Increased biliary pressure consequently dilates the duct system retrogradely, allowing larger stones to follow. Patients at risk of stone migration and thereby pancreatitis and jaundice have large ducts that can be detected by ultrasound assessment.

The authors report on their experience with endoscopic treatment of choledocholithiasis. Out of a total of 363 successful procedures of endoscopic papillosphincterotomy (EPS), choledocholithiasis was the indication for EPS in 270 patients (74.4%). Most often, EPS and extraction were performed in patients after cholecystectomy (79.6%) and those with choledocholithiasis and an in situ gallbladder, but free of stones (13.4%). In patients with concomitant cholecystolithiasis, EPS was carried out only in those cases in which surgery was contraindicated. EPS was performed in four cases of acute biliary pancreatitis. Removal of stones from the choledochus was successful in 95.5%. Of the total of 363 successful EPS's, complications were observed in 17 cases (4.7%), with a mortality of 1.1% (4 deaths). Most frequently, the causes included bleeding (1.9%) and perforation (1.1%). Of other complications, the authors noted acute pancreatitis, acute cholangitis and impaction of stone in the hepatocholedochus in two cases each. The complications required emergency surgery in six patients (35.3%).

This paper attempts to demonstrate the influence of gallstones, from different locations, on ultrastructural changes in pancreatic acinar cells. Forty-two gallstone patients with no record of clinical pancreatitis are the subjects of this study. Of these patients, 14 have cholecystolithiasis, 14 have choledocholithiasis, and 14 have primary hepatolithiasis. The findings reveal the following ultrastructural alterations of the pancreatic acinar cells: dilation of the rough endoplasmic reticulum, accumulation of lipid droplets, an increase of autophagic vacuoles, residual bodies and myelin figures, alteration of electron density of zymogen granules, and alteration of mitochondria. All these ultrastructural changes are similar to those of clinical acute pancreatitis. With three locations of calculi, these different kinds of gallstones have a similar affect on the fine structure of pancreatic acinar cells, and these changes occur regardless of the size of the common bile duct and the biochemical data. This suggests that irrespective of the location of the gallstones, subclinical cellular injury to acinar cells is caused.

An enteroscopic method that uses a pediatric colonoscope provides an alternative approach to the diagnostic and management problems arising in the setting of a Roux-en-Y limb hepaticojejunostomy or biliary diversion. Three patients with Roux-en-Y limb reconstructions who experienced recurrent cholangitis, recurrent pancreatitis, or choledocholithiasis in whom the technique was used are presented. The technique, which uses colonoscopic principles, is discussed along with the combined use of percutaneous transhepatic assistance. Enteroscopy of a Roux-en-Y limb is technically feasible and expands the diagnostic and management approach to biliary and pancreatic disease involving this postoperative anatomic condition.

Endoscopic retrograde sphincterotomy (E.R.S.) is rapidly becoming popular. In the past 5 years, E.R.S. was technically successful in 124 of 130 patients (95%) in whom it was attempted. One hundred twenty four had choledocholithiasis, and six had papillary stenosis after cholecystectomy. Urgent E.R.S. was performed for septic cholangitis in 12 patients and biliary pancreatitis in four. There were six patients with choledocholithiasis in whom sphincterotomy was not possible. Of the 118 patients with successful papillotomy for choledocholithiasis, spontaneous passage of calculi after E.R.S. occurred in 28 cases (24%), and instrumental extraction of stones was possible in 81 (69%). Duct clearance failed in nine patients (8%), mostly due to the large size of the retained stones. The largest stone extracted was 26 mm in diameter. The overall success rate of removing common bile duct stones was 109 in 118 cases (88%). In patients with papillary stenosis, E.R.S. was successful in relieving symptoms and biochemical cholestasis in six of six cases (100%). Complications occurred in only two patients. The complications were pancreatitis in one and hemorrhage in one. None of these patients required surgical treatment of the complication. Endoscopic retrograde sphincterotomy is effective for the removal of stones of the common bile duct, and at relieving the symptoms of papillary stenosis. It is safe in experienced hands and has led to only rare complications.

Acute biliary tract disease complicated intrauterine pregnancy in 26 patients seen during a 5 year period. Biliary symptoms were distinct and occurred during the first trimester in 7 patients, the second trimester in 5 patients, the third trimester in 12 patients, and in two early postpartum patients. Nine patients had marked hyperamylasemia which resolved with medical management, and no severe cases of pancreatitis occurred. Ultrasonography was used to confirm the presence of gallstones in 18 patients and demonstrated dilated intrahepatic ducts in one of two patients with surgically proved choledocholithiasis. Nineteen patients had cholecystectomy and cholangiography, and 4 had common bile duct explorations. Only two of seven patients who presented in the first trimester had term pregnancy. Diagnosis of cholelithiasis in pregnancy by ultrasonography is accurate and reliable. The risk to the fetus of radionuclide scanning and conventional radiography is not justified. Secondary hyperamylasemia is common but responds to conservative therapy. Operation may be delayed until delivery in most patients, with urgent exploration reserved for uncertainty in diagnosis, choledocholithiasis, or acute cholecystitis that does not resolve with medical measures.

Bile reflux into the pancreatic duct after impaction of a stone in a common pancreaticobiliary channel has been suggested to be the initiating factor in gallstone pancreatitis. Such reflux would require that the impacted stone be smaller than the length of the common channel. The incidence of common channels was studied and gallstone size was compared with common channel length in patients with gallstone pancreatitis and those with cholelithiasis or choledocholithiasis without pancreatitis. Sixty-seven per cent of patients with gallstone pancreatitis had a common channel present on intraoperative cholangiography versus 32% of patients with cholelithiasis or choledocholithiasis without pancreatitis (p less than 0.005). Common channel length was greater than the diameter of the smallest stone in nine of 27 patients with gallstone pancreatitis and in 13 of 109 patients with cholelithiasis or choledocholithiasis without pancreatitis (p less than 0.025). In conclusion, common channels are more frequent in patients with gallstone pancreatitis than in patients with other biliary tract disease. Furthermore, gallstone pancreatitis is associated with stones that are smaller than the common channel, which favors obstruction of both pancreatic and bile ducts while allowing reflux of contents between them.

Tumour-associated antigen CA 19-9 was determined in serum from 166 patients (30 without gastro-intestinal disease, 32 with liver cirrhosis, 9 with choledocholithiasis, 65 with acute or chronic pancreatitis and 30 with malignant tumors in the region of pancreas and bile passages). The specificity of CA-19-9 as tumour marker was 97% in patients without gastro-intestinal disease, but in those with liver cirrhosis or choledocholithiasis it was only 56% and 44%, respectively. In particular, cholestasis reduced specificity. Acute pancreatitis in its initial attack gave false-positive CA 19-9 values in 27% of cases, repeated bouts in chronic recurrent pancreatitis in as many as 50%. In chronic pancreatitis the specificity was 90%. Malignant tumours of pancreas and bile ducts were diagnosed with a sensitivity of 80%. Determination of CA 19-9 in pure pancreatic secretion failed to differentiate between the control group (30), chronic pancreatitis (21) and carcinoma of the pancreas (22).
