An approach to the diagnosis and treatment of patients with presumed functional disorders of the biliary tract (biliary dyskinesia) is described. The current diagnostic criteria are pain compatible with biliary pain in the absence of gallstones and other organic gastrointestinal disease, or other disorders which might produce abdominal pain, together with reproduction of the patient's symptoms by cholecystokinin, or morphine, or both. Other diagnostic methods are described together with their limitations. The results of operation in 38 of 45 patients seen in this Unit during the past six years are presented. The results were poor in 20% of patients, but two-thirds of the group have had good results in the short term.

In 5 human subjects, 95% pure cholecystokinin (CCK) given as a background infusion in doses of 42, 84, or 168 pmol kg-1 h-1 did not significantly alter acid secretion in response to graded doses (11-300 pmol kg-1 h-1) of synthetic human gastrin-17-I. The 168 pmol kg-1 h-1 dose of CCK produced maximal pancreatic amylase output. In 3 subjects, 337 pmol kg-1 h-1 of CCK slightly stimulated acid secretion when given alone and tended to reduce acid secretion in response to gastrin, but each of the subjects experienced cramping abdominal pain. The increment in acid secretion produced by CCK alone was similar to that produced by maximally effective doses of carboxyl-terminal octapeptide of CCK. In dogs with gastric and pancreatic fistulas, 168 pmol kg-1 h-1 of CCK produced maximal pancreatic protein output and slightly stimulated gastric acid secretion. In dogs with gastric fistulas and Heidenhain pouches, the lowest dose of CCK that inhibited gastrin-stimulated acid secretion was 674 pmol kg-1 h-1. We conclude that in man and dog 95% pure CCK weakly stimulates gastric acid secretion and inhibits gastrin-stimulated acid secretion but these actions occur only with doses of CCK that are maximal or supramaximal for pancreatic enzyme secretion. Because of the high dose requirement, these effects are unlikely to be physiologically significant.

Endoscopic retrograde cholangiopancreatography (ERCP) was carried out in 98 patients with unexplained abdominal pain or known pancreatitis with recurrent pain. Patients with jaundice were excluded from the study. In 38 patients with a clinical diagnosis of pancreatitis, the radiological findings on ERCP were graded according to the criteria of Kasugai et al. Advanced pancreatitis was found in 20 patients (52,5%), moderate changes in 7 (18,4%) and minimal-change pancreatitis in 6 (15,8%). ERCP had normal pancreatic function tests. In 35 patients investigated for unexplained abdominal pain, changes consistent with pancreatitis were found in 7, pancreatic carcinoma in 5, a duodenal ulcer in 2, gallstones in 1 and a duodenal tumour in 1. ERCP was normal in 19 patients. A comparison of the findings on ERCP and the standard secretin-cholecystokinin pancreatic function test was available in 52 patients. There was a good agreement between the two tests in the patients with advanced or moderate pancreatitis as revealed by ERCP, but less agreement in the patients with minimal-change pancreatitis. A few patients with clinical pancreatitis and abnormal ERCP had normal pancreatic function tests. ERCP increases the diagnostic yield in patients suspected of having pancreatitis and is at present the only reliable method of diagnosing pancreatic carcinoma which is not evident by other non-operative techniques. ERCP is also of value in the assessment of the severity of pancreatitis and is a necessary investigation before pancreatic surgery to confirm or exclude cyst formation or the site of duct obstruction. The finding of an unsuspected cyst at ERCP necessitates early operation because of the danger of introducing infection during the procedure.

Clues to the pathogenesis of functional pain syndromes may be derived from the study of stimuli that precipitate or aggravate symptoms. In this study, cholecystokinin octapeptide (CCK-8, 0.06 microgram/kg) and placebo were given by intravenous infusion (5 min) in random order to control subjects and four groups of patients with unexplained abdominal pain. Induction of pain and nausea were assessed by linear analogue scales while sympathoadrenomedullary responses were assessed by serial changes in plasma concentrations of noradrenaline, adrenaline and dopamine. Scores for pain and nausea were low after infusion of placebo. After infusion of CCK-8, pain scores were significantly higher in patients with spontaneous pain than in control subjects, but significant increases in nausea were restricted to patients with irritable bowel syndrome and a subgroup of patients with pain after cholecystectomy. Although some groups showed increases in plasma concentrations of catecholamines after the infusion of CCK-8, the size of these increases was neither consistent among patients within each group nor predictive of scores of pain and nausea in individual subjects. Pain during the infusion of CCK-8 was a feature common to patients with diverse functional pain syndromes, and did not appear to be attributable to activation of the sympathetic nervous system.

Recent publications continue to refine the technique and interpretation of hepatobiliary scanning. Studies related to the evaluation of suspected acute cholecystitis have shown that morphine-augmented hepatobiliary imaging may not overcome the problem of false-positive study results in severely ill patients and the criterion for a normal study should be gallbladder visualization within 30 rather than 60 minutes. In patients with suspected acute cholecystitis, nonvisualized extrahepatic activity despite good hepatic uptake is highly predictive of acute cholecystitis, usually with biliary obstruction. The limitations of cholecystokinin-hepatobiliary imaging studies in patients with abdominal pain syndromes were defined and its use in evaluating common bile duct dynamics, and duodenogastric reflux was explored. Unusual findings and less-common uses of hepatobiliary scanning were reported, including assessment of conjoined twins, liver transplantation, primary biliary cirrhosis, gallbladder perforation, and persistent splenic visualization.

We have investigated the relationship between cholecystokinin levels and abdominal pain in patients with chronic pancreatitis. The baseline and postprandial cholecystokinin levels were measured in 15 patients with chronic pancreatitis (8 with and 7 without abdominal pain) and in a reference group of 8 healthy subjects. The baseline, 30 and 60 min postprandial plasma cholecystokinin levels were significantly (p less than 0.05) higher in the patients with pain as compared with the other two groups. No correlation was observed between increased cholecystokinin levels and impairment of the exocrine pancreatic function as assessed by the NBT-PABA test. The increased cholecystokinin levels might be an important factor in the genesis of pain in chronic pancreatitis.

The presently available methods of study of small bowel motility in humans include manometry (or electromyography) which records the temporospatial organization of bowel contractions and determination of intestinal transit time. Investigation of subjects with the irritable bowel syndrome has shown that the small intestine has its part in the motor disturbances. The characteristics of normal motility of the small intestine are well known: the migrating motor complex (MMC) develops during the interdigestive period, typical contractions are seen during phases 2 and 3 of the MMC, the nature and the duration of the motor response to alimentation have been described. In patients with IBS, the production of the MMC is irregular during the day hours; this is most likely due to environmental solicitations and it is recognized that intensive aliess can cause transient interruption of the development of cycles. On the other hand, the MMC develops normally during sleeping hours. Contraction derangements such as non propulsed repeated contractions in the proximal intestine and contractions propulsed too frequently in the small intestine may be found during phase 2. Some of the abnormal contractions coincide with abdominal pain. After meals, the duration of interruption of the MMC is shorter than in the normal subject. Transit time is shortened in patients with diarrhea, lengthened in patients with constipation. Patients with IBS respond excessively to certain stimuli: for instance, the motor response to cholecystokinin is increased compared to the normal subject. Intake of fatty ingesta is followed by the same type of reaction: pain is often associated with abnormal contractions.(ABSTRACT TRUNCATED AT 250 WORDS)

Using a percutaneous transhepatic cholangioscopy (PTCS) catheter, sphincter of Oddi motility was measured in a patient with papillary stenosis secondary to bile duct stones. Prior to sphincterotomy, intramuscular injection of 20 micrograms caerulein did not inhibit pathological contraction waves of the sphincter of Oddi or relieve abdominal pain. Endoscopic sphincterotomy of the lower segment of the sphincter of Oddi resulted in recovery of the normal response to caerulein, i.e. relaxation of the sphincter of Oddi. This observation indicates that the pathological contraction and lack of relaxation to cholecystokinin in a patient with papillary stenosis is due to high common bile duct pressure. The measurement of motility of sphincter of Oddi via the PTCS route is useful in diagnosing motor disorders in the sphincter of Oddi and is helpful in deciding to perform endoscopic sphincterotomy.

Between 1978 and 1985, 11 girls and one boy underwent an elective operation for a congenital choledochal dilatation associated with an anomalous biliopancreatic junction. In 10 out of these 12 cases the children suffered several episodes of abdominal pain, and the diagnosis was missed since a jaundice appeared. The ultrasonographic examination demonstrated in all cases a dilatation of both extra- and intrahepatic bile ducts. The preoperative diagnosis was always established by the mean of a transhepatic cholangiography (8 cases) or a percutaneous cholecystography (4 cases), which showed in every case a dilated choledochus, and a common biliopancreatic channel, 15 to 35 mm long. A high amylase level was found in the bile in 10/10 cases when it was measured. A cholecystokinin test was performed in 4 cases, resulting in each case in a considerable increase of amylase and lipase levels in bile. All children were treated by excision of the dilated choledochus and gallbladder, followed by an hepaticojejunostomy with a Roux en Y loop. The follow-up is 6 months to 5 years for 9 children: 8 are cured, and on girl, who had a major dilatation of the left intrahepatic bile ducts, suffered from episodic abdominal pain and an episode od cholangitis 6 years after the operation. The role of such a common channel in the pathogeny of congenital choledochal cysts, acute pancreatitis in children, and biliary carcinomas in young adults is discussed according to the literatures of the last 10 years.

Plasma cholecystokinin (CCK) responses after ingestion of a test meal in patients with mild chronic pancreatitis having abdominal pain were studied with a radioimmunoassay using the CCK specific antiserum (OAL-656) produced by a novel immunization procedure. Mean concentration of the fasting plasma CCK determined using CCK-8 as a standard was 31.5 +/- 5.8 pg/ml in six patients who had mild impaired exocrine function with pain, and was significantly higher than 10 healthy subjects (9.8 +/- 1.8 pg/ml). In those patients, the ingestion of a liquid test meal led to a peak of 75.1 +/- 25.4 pg/ml at 30 min, and the 120-min integrated CCK response (5427 +/- 1217.3 pg X min/ml) was significantly higher than in healthy subjects (1538 +/- 110.1 pg X min/ml).
