The accuracy and possible clinical value of grey scale ultrasonography in the detection of gallstones has been prospectively studied in 100 unselected patients presenting with recurrent biliary colic, acute cholecystitis or acute pancreatitis. Adequate visualization of the gallbladder was obtained in 79 cases, with 3 false positive and no false negative reports. Oral cholecystography remains the initial investigation of choice in patients presenting with recurrent biliary colic, but grey scale ultrasound has been shown in this study to be a reliable means of detecting gallstones in the 'acute' situation, when conventional contrast radiology is of limited value.

During a 2-year interval, we identified 10 patients with symptoms of pancreaticobiliary disorders and small choledochoceles by endoscopic retrograde cholangiopancreatography. Patients ranged from 36 to 89 years of age. Eight were female. Seven presented with recurrent, acute pancreatitis, two presented with biliary colic, and one presented with cholangitis. Dilated common bile ducts were seen in four patients, and no other biliary lesions were demonstrated in any patients. Five patients were shown to have normal gallbladders by ultrasonographic or computed tomographic criteria. Choledochoceles were identified endoscopically as a bulge above or involving the ampulla. Diagnosis was confirmed by cholangiography. All patients underwent successful unroofing of the choledochocele and sphincterotomy of the common bile duct. One pancreatic sphincterotomy was performed for pancreatic ductal obstruction. We encountered no complications. Hospital stays ranged from 1 to 4 days. Follow-up intervals ranged from 2 to 20 months. At this time, no patients have had any recurrence of symptoms, and none has required rehospitalization or surgery.

Between Jan. 19, 1989 and Nov. 23, 1990, 170 patients with symptomatic cholelithiasis were evaluated for possible treatment by extracorporeal shockwave lithotripsy (ESWL). Thirty-one patients were not eligible for treatment, 28 (16%) because of nonvisualization of gallstones by ultrasonography and 3 (2%) because polyps were erroneously diagnosed on ultrasonography. Thirteen (8%) patients failed to comply with the protocol, leaving 126 patients for assessment. At the time of writing, the treatment success rate is 57% at 6 months and 69% at 9 months. Treatment failed in 21 (17%) patients because of unsatisfactory fragmentation in 16 (13%) patients, frequent biliary colic in 3 (2%) patients, acute pancreatitis in 1 (0.8%) patient and severe bile-salt-induced diarrhea in 1 (0.8%) patient. Complications included biliary colic (40 patients), mild diarrhea on bile salts (24 patients), severe diarrhea (1 patient), macroscopic hematuria (4 patients), acute pancreatitis (2 patients) and vagal shock (1 patient). This study demonstrates the effectiveness (87%) of the lithotripter in reducing gallstones to fragments 5 mm in diameter or smaller. However, complete disappearance of these fragments with adjuvant bile-salt therapy may take many months.

From a computerized database comprising 28 pertinent items in each of a consecutive series of 664 patients with cholelithiasis, differences were studied between men and women. In 52 patients there was a documented attack of acute pancreatitis (7.8%). Twenty-five of 174 men had pancreatitis, compared with 27 of 490 women (p less than 0.0001). Men developed gallstones later in life than women, but suffered gallstone pancreatitis earlier in life and in the course of their gallstone-related disease. A history of flatulent dyspepsia, chronic cholecystitis, and biliary colic was less common in men than in women with pancreatitis (p less than 0.0001). Men with pancreatitis had fewer stones in their gallbladders than did women (p = 0.0002). The cystic duct and the common bile duct in the pancreatitic patient were more likely to be dilated (p less than 0.0001). In the nonpancreatic group, these ducts were larger in men. Pancreatic duct reflux on operative cholangiography was more common both in patients with pancreatitis 62% cf 14% (p less than 0.0001), and in men (p less than 0.001). Predisposition to pancreatitis relates to duct size rather than stone size per se. Men are more susceptible to gallstone migration at an early stage of their disease. In addition they have a larger diameter duct system and possibly a different anatomic disposition of the sphincter of Oddi, which predisposes them to a higher incidence of pancreatitis than women. The data suggest that it is cystic duct size that is critical in the pathogenesis of gallstone pancreatitis.

500 patients with hepatobiliary and pancreatic disease due to Ascaris lumbricoides infection were studied. 274 patients had duodenal ascariasis, 171 biliary ascariasis, 40 hepatic ascariasis, 8 gall bladder ascariasis, and 7 pancreatic ascariasis. Five clinical presentations were recognised: acute cholecystitis (64 patients), acute cholangitis (121), biliary colic (280), acute pancreatitis (31), and hepatic abscess (4). Ascarides in the duodenum (which were seen to invade only the ampullary orifice) induced either severe biliary colic or episodes of acute pancreatitis. 27 patients had pyogenic cholangitis and were managed by surgical (2) or endoscopic (25) biliary decompression and drainage. Removal of worms from the ampullary orifice and their extraction by mouth led to rapid relief of biliary colic (214 patients) and acute pancreatitis (16). 4 patients died (acute pancreatitis 2, pyogenic cholangitis 1, hepatic abscess 1). In 12 patients worms persisted in the biliary tree at 3 weeks; dead worms were removed from the biliary tree by surgery (5 patients) or with an endoscopic basket (7). Worms moved out of the ductal system in 211 patients. During a mean follow-up of 48 months (SD 14), 76 patients had worm re-invasion of the biliary tree due to ascaris re-infection. Intrahepatic duct and bile duct calculi developed in 7 patients in whom dead worms formed the nidus of stones.

Twenty-three of 229 symptomatic patients undergoing cholecystlithotripsy underwent surgical intervention: 22 of the patients had cholecystectomy performed (five also undergoing choledochotomy) and one patient had a cholecystostomy. Of these 23 patients, five were lithotripsy failures, five developed acute pancreatitis, one had acute cholecystitis, and one had cholangitis. One patient had her gallbladder removed incidentally at the time of surgery for a bleeding gastric ulcer. Ten patients underwent surgery for recurrent biliary pain, probably related to fragment passage via the cystic duct. We suggest that up to 16 of these 23 patients did not necessarily require cholecystectomy, i.e. five patients with pancreatitis, one patient with cholangitis and ten patients with recurrent biliary colic. Conservative and/or endoscopic management may be successful in the first instance to allow further treatment with lithotripsy in the majority of patients. If, however, the expertise to perform endoscopic sphincterotomy is not available or the patient declines further lithotripsy, then resort to surgery may be necessary. We propose that it is the responsibility of the management team in charge of the lithotripsy unit to inform both the patient and the referring clinicians of the possible side-effects and outcome of treatment in an attempt to avoid unnecessary surgical procedures.

Extracorporeal shock-wave cholelithotripsy was carried out in 135 symptomatic patients with radiolucent gallstones, followed by oral bile acid dissolution to assess the resultant stone disappearance rates. Fragmentation was satisfactory (all fragments less than 5 mm in diameter) in 34 patients (25%) after a single session of lithotripsy, and in 65 (48%) after multiple sessions. The overall satisfactory fragmentation rate was significantly higher in patients with single stones less than or equal to 20 mm in diameter when compared with those with larger solitary stones (71% vs. 38%, p less than 0.05), as it also was in all subjects with solitary stones when compared with those with multiple stones (60% vs. 34%, p less than 0.05). After 6, 9, and 12 mo of oral bile acid treatment, the stone-free rates were significantly higher in patients with satisfactory than in those with partial fragmentation (55% vs. 0%, 80% vs. 29%, and 90% vs. 33%, respectively; p less than 0.05). Only 1 of the 7 patients who had previously undergone endoscopic sphincterotomy for concomitant choledocholithiasis was free of stones after 1 yr of dissolution. During dissolution therapy, of the 102 patients in whom fragmentation had occurred, 1 (1%) developed mild acute pancreatitis, 23 (23%) suffered attacks of biliary colic, and 6 (6%) required cholecystectomy. We conclude that the result of fragmentation appears to be a major determinant of the success and rapidity of subsequent oral bile acid dissolution, and that when satisfactory, it allows for complete stone disappearance in most patients within the following year. A comparison of the present results with those of previous original studies suggests that to achieve such satisfactory fragmentation, patients should be selected on the basis of their stone characteristics, which optimally should present as solitary gallbladder calculi less than 20 mm in diameter. Furthermore, real-time ultrasonographic monitoring should be used during lithotripsy with a transducer centered along the shock-wave axis. Despite the innocuousness of the shock waves, the incidence of fragment migration and its possible complications, in our experience, emphasizes the need to restrict at present this nonoperative approach to the treatment of symptomatic gallstone disease.

It was felt that the apparent specificity of the amylase-to-creatine clearance ratio (ACCR) in several previous studies of pancreatitis might reflect a failure to utilize adequately ill control subjects. The ACCR and the renal clearances of beta 2-microglobulin (B2-m), similarly related to creatinine (BCCR) as well as the urinary concentration of albumin, were compared in 27 patients with acute pancreatitis, 8 with a perforated peptic ulcer and 7 with mild biliary colic, during the first 5 days in hospital. Acute pancreatitis was graded as mild (6), moderate (14) or severe (7), using a combination of clinical data, diagnostic peritoneal lavage and multiple criteria. Further assessment of the severity of the acute illness was obtained from measurement of C-reactive protein (C-RP). Lowest C-RP levels were found in the patients with mild pancreatitis and biliary colic, and highest levels in the patients with severe pancreatitis and perforated ulcer (P less than 0.002). Similarly, ACCR and BCCR levels were significantly lower in the two mild groups than in the two severe ones (P less than 0.01 and less than 0.002 respectively), although plasma amylase was raised only in patients with pancreatitis and plasma B2-m was similar in all groups. Electrophoresis of urine showed dense bands of tubuloprotein in patients from both severe groups. Urine albumin was higher in severe pancreatitis than in perforated ulcer (P less than 0.1), perhaps indicating a more specific glomerular lesion in pancreatitis. Thus a rise in amylase clearance appeared to be related to the severity of the acute illness, and may be a component of a non-specific tubuloproteinuria. In this study patients with a perforated peptic ulcer had increases in ACCR similar to those seen in patients with severe pancreatitis, and we are therefore doubtful whether ACCR has any role in the clinical diagnosis of pancreatic disease.

Choledochocele is a rare abnormality involving the intramural segment of the common bile duct. It may present clinically as recurrent acute pancreatitis, biliary colic, or cholestatic jaundice. A choledochocele may be easily overlooked by the conventional diagnostic methods, such as upper gastrointestinal series, intravenous cholangiogram, abdominal ultrasound, and computed tomography. Endoscopic retrograde cholangiopancreatography is helpful in demonstrating a choledochocele. Additionally, in selected cases, a choledochocele may be effectively managed by endoscopic sphincterotomy. We present the clinical, endoscopic, and radiographic findings in a series of 8 patients with choledochocele. The radiologic technique most useful in demonstrating a choledochocele at the time of endoscopic retrograde cholangiopancreatography is detailed. The pathogenesis, differential diagnosis, and relevant current literature pertaining to choledochocele are discussed.

Early surgery for biliary pancreatitis has resulted in a need for an accurate method of gallstone detection in acute pancreatitis. Fifty patients with acute pancreatitis were studied prospectively to assess the diagnostic value of Radionuclide Biliary Scanning (RBS) performed within 72 hours of an attack. To assess the general accuracy of RBS a further 154 patients with suspected acute cholecystitis or biliary colic were similarly studied. There were 34 patients with biliary pancreatitis and 18 (53%) had a positive scan (no gallbladder seen). There were 16 patients with non-biliary pancreatitis and 5 (31%) had a positive scan. All 51 patients with acute cholecystitis had a positive scan, as did 82% of the 51 patients with biliary colic. There were 52 patients with no biliary or pancreatic disease and none of these had a positive scan. RBS is highly accurate in confirming a diagnosis of acute cholecystitis or biliary colic. However, it cannot be relied on to differentiate between biliary and non-biliary pancreatitis and should certainly not be used as the basis for biliary surgery in these patients.
