Extracorporeal shockwave lithotripsy for common bile duct stones.

BACKGROUND: Successful extraction of common bile duct stones after endoscopic sphincterotomy may be achieved in 86-96 per cent of cases. However, some stones are too large to be removed in this manner. This study looks at the role of extracorporeal shock-wave lithotripsy to break up common bile duct stones as an adjunct to sphincterotomy in patients with stones greater than 10 mm in size. METHODS: Twenty-seven patients with large (10-35 mm) common bile duct stones were treated with piezoelectric generated extracorporeal shock-wave lithotripsy (ESWL) following failed stone extraction after endoscopic sphincterotomy (ES). The stones were visualized ultrasonographically and a piezolith 2300 Wolf lithotripter used to administer the shockwaves. RESULTS: Visualized stone fragmentation was reported in 20 of 48 sessions. Clearance of targeted stones was achieved in 18 of the 27 patients, but actual duct clearance was demonstrated in only 17 of the 27. There were few adverse effects and mortality was nil. CONCLUSION: This study concludes that ESWL following failed ES is a useful additional treatment option for very large bile duct stones, but should only be used after surgical risk and past history of biliary disease have been carefully reviewed and found to contraindicate conventional surgical management. An algorithm of treatment options for common bile duct stones is presented.

Prevalence and natural history of distal common bile duct stenosis in alcoholic pancreatitis.

Distal common bile duct stenosis was observed in 16 (9%) of 170 alcoholic patients admitted to a Veterans Administration Medical Center in the last five years. The following clinical and biochemical features were significantly more common (P less than 0.05) among the 16 patients with common bile duct stenosis than in 154 without: jaundice, cholangitis, hyperbilirubinemia, alkaline phosphatasemia, pancreatic calcification, and malabsorption. Surgical decompression of biliary tree was necessitated in 13 of 16 cases due to obstructive jaundice in seven, cholangitis in four, portal fibrosis in one, and persistent abdominal pain in one. The mean (+/- SE) time interval between initial serum alkaline phosphatase elevation and surgical intervention was 308 +/- 108 days. Liver histology in eight cases was remarkable for portal fibrosis in seven and biliary cirrhosis in one. These data suggest that distal common bile duct stenosis is a progressive lesion which is quite prevalent in patients with advanced pancreatic disease of alcoholic etiology.

[Hydrodynamic and radiologic examination of the common bile duct].

The operative study of the common bile duct was carried out with the hydrodynamics methods (flow and resting pressure) in 433 patients and with the operative cholangiography in 383 patients. The hydrodynamics explorations pointed-out a margin of mistake due to falses positives and negatives of the 2.7% and the operative cholangiographies of the 8.6%. The association of both methods, hydrodynamics and radiologycs, allowed us to estimate that the diagnostic mistake is reduced to 0%. It is established in this work the necessity of carring out the flow, the measure of the resting pressure and the cholangiographies; in all the patients that are operated on the biliary tract because the diagnostic accuracy is the 100%. It is discussed the value of the diameter of the common bile duct for affirming the eventual existence of obstruction of the lower part of the common bile duct and the values are correlated, measured in mm., with pathological founds. It is considered the value of the hydrodynamics methods in the diagnostic of the stenosis of the sphincter of Oddi.

Laparoscopic choledochoscopy and extraction of common bile duct stones.

Various strategies have been proposed for the treatment of common bile duct stones encountered during laparoscopic cholecystectomy (LC). Eighty-three patients who had choledocholithiasis discovered during or just prior to LC are included in this study. These patients were treated by various modalities including preoperative, intraoperative, and postoperative endoscopic retrograde cholangiopancreatography and sphincterotomy, laparoscopic choledochotomy, transcystic duct-common bile duct (TCD-CBD) exploration, and conventional "open" common duct exploration. Sixty-six patients were successfully treated with TCD-CBD exploration. They were discharged on average 2.6 days postoperatively and were able to return to normal physical activities within 7 days of discharge. There was minimal morbidity and no mortality. The technique of TCD-CBD exploration is described in detail. The role of laparoscopic choledochotomy and endoscopic sphincterotomy for management of common duct stones in patients undergoing laparoscopic cholecystectomy appears limited.

Sonography of the common bile duct: value of the right anterior oblique view.

The common hepatic and proximal common bile ducts (common duct) lie anteriorly and generally to the right of the portal vein in the porta hepatis. This constant anatomic relationship can be used to demonstrate the common duct and to differentiate it from the portal vein by gray scale ultrasonography. The patient is scanned longitudinally from the right anterior abdominal wall with the ultrasound beam directed posteromedially until two tubular structures are demonstrated in the porta hepatis. The more anterior tubular structure in this projection is the common duct. If the common duct is less than 3 mm in diameter, it may not be clearly delineated. In these cases the absence of common duct dilatation can be inferred. The usefulness of this view for detecting common duct dilatation was evaluated in a series of 101 consecutive cases proven by surgery, autopsy, or cholangiography. The overall accuracy was 96% (four false negative studies; no false positives). We conclude that sonography should be the imaging procedure of choice for suspected extrahepatic biliary obstruction if the serum bilirubin level precludes intravenous cholangiography.

Nonoperative measurement of pancreatic and common bile duct pressures with a microtransducer catheter and effects of duodenoscopic sphincterotomy.

Duodenoscopic manometry of the pancreatic duct (PD) and common bile duct (CBD) using a microtransducer catheter was distinct advantages over infusion manometry, giving absolute values of in situ intraluminal pressure. Microtransducer manometry was performed without medication in 49 patients with gallbladder stones (10), common bile duct stones (24), hepatic duct stones (6) and common bile duct dilatation (9), and was successful in 42 (86%) for PD and 36 (73%) for CBD. Ductal pressures showed respiration-synchronized biphasic variations superimposed by the arterial pulsation effect. Considerable postural change of the pressure values suggested that the recording posture should be predetermined. The PD-to-duodenum pressure gradient was higher than the CBD-to-duodenum gradient in most cases. Both were lower than those obtained previously by infusion methods. No significant differences were found in pressure profiles of the four disease groups. Endoscopic sphincterotomy significantly reduced not only CBD pressure but also PD pressure.

Transcholecystic endoscopic choledocholithotripsy: successful management of retained common bile duct stone.

Removal of large common bile duct stones has been a continuing challenge. The feasibility and efficacy of transcholecystic endoscopic choledocholithotripsy in a high-risk patient are demonstrated in this report. The procedure requires an established cholecystostomy track, catheter dilatation of the cystic duct, and the application of electrohydraulic shock waves to the calculus. The use of a choledochofiberscope permits the passage of the electrohydraulic probe and minimizes complications by direct monitoring. Stone fragments are removed by basket retrieval. This procedure in conjunction with minicholecystostomy may obviate the need for surgery in selected high-risk patients with combined gallbladder and common bile duct stones.

Intraoperative choledochoscopic electrohydraulic lithotripsy for difficulty retrieved impacted common bile duct stones.

BACKGROUND: A difficultly retrieved, impacted distal common bile duct stone is sometimes encountered during supraduodenal common bile duct exploration. Transduodenal sphincteroplasty is usually performed when such stones cannot be retrieved by conventional methods, but not without risk. OBJECTIVES: To achieve clearance of such complicated stones and to avoid the potential risks of transduodenal sphincteroplasty. DESIGN: Prospective clinical trial. SETTING: Medical college-affiliated hospital and tertiary care center. PATIENTS: From July 1991 to April 1993, 10 patients met the following inclusion criteria: (1) an impacted distal common bile duct stone found during supraduodenal common bile duct exploration and (2) failure of conventional methods such as stone forceps, a basket, flushing with normal saline solution, or a Fogarty catheter to retrieve stones via the supraduodenal choledochotomy. Another 10 patients with the same problem, treated with transduodenal sphincteroplasty from February 1989 to May 1991, were used as a comparison group. INTERVENTION: Intraoperative choledochoscopic electrohydraulic lithotripsy was applied with continuous visualization through a choledochoscope. MAIN OUTCOME MEASURES: Effectiveness of stone fragmentation and possible complications. RESULTS: Stones were fragmented and successfully removed by a basket and flushing with normal saline solution. Mild oozing was noted in one patient, but soon stopped spontaneously. The mean operative time of the clinical trial group was significantly shorter (P = .004) than that of the comparison group; the mean postoperative stay was 4 days shorter. The complication rate of the clinical trial group (10%) was lower than that of the comparison group (40%). The 10 successfully treated patients of the clinical trial group remain well, with a mean follow-up of 22 months. CONCLUSION: Intraoperative choledochoscopic electrohydraulic lithotripsy is a safe and effective method for removal of impacted distal common bile duct stones.

Regression of liver fibrosis after biliary drainage in patients with chronic pancreatitis and stenosis of the common bile duct.

BACKGROUND: Chronic obstruction of the common bile duct may cause hepatic fibrosis and secondary biliary cirrhosis. METHODS: We studied liver-biopsy specimens from 11 patients with chronic stenosis of the common bile duct due to chronic pancreatitis; all the patients had undergone liver biopsy before or at the time of surgical biliary decompression and underwent a subsequent liver biopsy for various clinical reasons. The patients were followed as part of a prospective study of 501 patients who had been treated for chronic pancreatitis. Two pathologists, who were unaware of the sequence of specimens, graded fibrosis on a scale of 0 (none) to 3 (cirrhosis). RESULTS: The 11 patients were all men. Chronic pancreatitis was due to alcohol abuse in 10 of the men; 1 had idiopathic disease. The median age at diagnosis was 38 years. The median interval between the first and second liver biopsies was 2.5 years (range, 0.3 to 9.0). The two patients who had restenosis of the biliary anastomosis were excluded from the analysis of fibrosis. In the group of nine patients without restenosis, the second specimen showed significant improvement in fibrosis (P=0.01). The fibrosis improved by two grades in two patients and by one grade in four patients; in three patients, the grade did not change. The pathologists agreed on the grading of specimens from 10 of the 11 patients. CONCLUSIONS: In patients with chronic pancreatitis and stenosis of the common bile duct, liver fibrosis may regress after biliary drainage.

Biliary stenting for management of common bile duct stones.

Large and multiple common bile duct stones may defy extraction despite an adequate endoscopic papillotomy. We treated 65 patients with symptomatic bile duct stones with endoscopic stents after failed attempts at stone extraction. Of the 65 patients, bile duct stones were extracted in eight at a second attempt, 29 underwent elective surgery and 28 patients were followed with the stent in situ for 21-52 months (median 42 months). During follow up, two patients had recurrent pain and two required surgery. The remaining 24 patients remained asymptomatic. Biliary stenting is a safe and effective mode of treatment for common bile duct stones in patients who have failed stone extraction after endoscopic papillotomy.

[A device for performing drainage into common bile duct].

A new original instrument is proposed for draining the cystic duct into the common bile duct through the stump. The device combines a reliable fixation of the drainage tube in the stump of a narrow (less than 3 mm) or scared altered cystic duct and the not traumatically embedded cannula into the common bile duct.

Extrahepatic peribiliary glands express alpha-amylase isozymes, trypsin and pancreatic lipase: an immunohistochemical analysis.

We examined expression of alpha-amylase isozymes (pancreatic and salivary), trypsin and pancreatic lipase on the epithelium of extrahepatic peribiliary glands immunohistochemically using 53 autopsied normal extrahepatic bile ducts. Three parts of the extrahepatic bile duct (common bile duct, intrapancreatic bile duct and bile duct at the ampulla of Vater) were examined in each case. Histologically, the extrahepatic bile duct harbored branched tubular glands (extrahepatic peribiliary glands). Extrahepatic peribiliary glands were few in the common bile duct and intrapancreatic bile duct and numerous in the bile duct at the ampulla of Vater. Immunohistochemically, pancreatic alpha-amylase was expressed in the epithelium of extrahepatic peribiliary glands in 42 cases (79%). Salivary alpha-amylase was expressed in the epithelium of the glands in 38 cases (72%). Trypsin was expressed in the epithelium of the glands in 32 cases (60%). Pancreatic lipase was expressed in the epithelium of the glands in 45 cases (85%). The immunoreactivity of these enzymes was granular and located in the supranuclear cytoplasm (corresponding to the Golgi apparatus) of the epithelium of the glands. We confirmed the specificity of the immunoreactivity of these enzymes with various methods. These results suggest that extrahepatic peribiliary glands produce alpha-amylase isozymes, trypsin and pancreatic lipase and secrete these enzymes into lumens of the extrahepatic bile duct. The secreted enzymes may play an important role in the physiology of the extrahepatic bile duct and bile.

A mathematical approach to the common bile duct.

Changes in the shape of the common bile duct (CBD) can be expressed mathematically by measuring the C.B.D.-diameter at five points and expressing these measurements as a percentage of the mean diameter. Variations in magnification are compensated for by relating the mean diameter to the length of the C.B.D. By comparing the shape of the C.B.D. in patients with various diseases with the shape of the normal common bile duct it was possible to define pathognomonic signs of various diseases of the extrahepatic biliary system. Indirect signs of pathology of the extrahepatic bile ducts are discussed.

Future Treatment of Common Bile Duct Stones.

Management options for patients found to have common bile duct stones have expanded as a function of improved instrumentation and radiographic support. Technological advances initially lead to increased costs but eventually result in improved quality for patients. Controversy exists for patients with either soft clinical findings or stones found at the time of laparoscopic cholecystectomy. As laparoscopic common duct exploration becomes more widespread the need for perioperative ERCP will likely decrease; however, this will depend on the experience of the surgeons at a given institution. Common bile duct stones found at the time of laparoscopic cholecystectomy can be approached in a variety of different ways. The most commonly used methods are laparoscopic transcystic common bile duct exploration, laparoscopic choledochotomy with common bile duct exploration, open common bile duct exploration, laparoscopic antegrade sphincterotomy, and postoperative ERCP. In the future, the treatment goal of biliary lithiasis will be to accomplish cholecystectomy and removal of bile duct stones in a single stage. Advances in fiberoptic technology will make transcystic duct exploration more effective, but it is likely that sphincterotomy (antegrade or retrograde) will be used preferentially for the distally impacted stone.

Granular cell tumor of the common bile duct.

Granular cell tumor most commonly appears in the tongue and skin, but has been found in varied locations (10). There are now 14 reported cases of the lesion occurring in the common bile duct. In most of these 14 cases, it has affected black females in their thirties. The lesion is most often benign. It should be considered in the differential diagnosis of obstructive jaundice secondary to bile duct tumors, especially if other granular cell tumors are present. This is the first reported case of pancreaticoduodenectomy for granular cell tumor of the common bile duct.

[The common channel syndrome associated with cystic dilatation of the common bile duct. Apropos of a case complicated by lithiasis of the common channel].

Perduodenoscopic retrograde cholangiography in a 15 year old boy with cystic dilatation of common bile duct demonstrated lithiasis of Vater's ampulla and collateral shunt for Wirsung's duct in the form of a functional Santorini duct. Cases of combined cystic dilatation of common bile and Vater's ducts reported in the literature are reviewed and a study conducted of frequency of cystic dilatation of common bile duct, its classification as described by Longmire and Hadat (enlarging that proposed by Alonso-Leij), and its diagnosis and complications. Routine retrograde cholangiography can delect lithiasis of Vater's ampulla and allow preoperative determination of therapy. Current investigatory procedures for these anomalies have allowed rediscussion of the etiopathogenicity of cystic dilatation of common bile duct and a tendency towards a duoalist hypothesis, without its definite confirmation at the present time.

Stenosis of the common bile duct in chronic pancreatitis.

The incidence of common bile duct stenosis in patients with chronic pancreatitis was studied in a consecutive series of patients admitted for endoscopic retrograde cholangiopancreatography (ERCP). Thirty-six out of 79 patients (46 per cent) with moderate or advanced chronic pancreatitis as defined by radiological criteria were found to have a stenosis of the intrapancreatic portion of the common bile duct. There were no age or sex differences between the patients with and without biliary stenosis, but significantly more patients with stenosis had advanced chronic pancreatitis. In about two-thirds of the patients the stenosis was smooth, symmetrical and tapering. In the remaining cases, a shorter stricture of the hour-glass type was found. A complete obstruction was never seen. About one-half of the patients with bile duct stenosis were icteric at the time of the investigation. The jaundice resolved spontaneously in all but 1 patient in 3-42 (median 14) days. Stenosis of the common bile duct is a frequent complication of chronic pancreatitis, but biliary-enteric bypass operation seems to be unnecessary in the great majority of the patients.
