Late results of primary repair and follow-up in 53 patients with injuries to the common bile duct occurring during cholecystectomy (distal perforation, tears, ligation or suture).
The late results of primary repair of accidental injuries to the common bile duct occurring during cholecystectomy were evaluated in 53 cases. These lesions occurred in 20 patients who had distal perforation produced by the Bakes dilator, in 17 cases with accidental tearing of the anterior or posterior wall of the common bile duct, and in 16 cases in whom the common bile duct was accidentally ligated or sutured. In cases of perforation, choledochostomy plus suturing of the perforation had a high operative mortality and 4 out of 6 cases developed benign stricture soon after surgery. When sphincteroplasty or choledochoduodenostomy was added, a stricture developed in only 1 out of 7 cases. In cases with accidental tears, suturing of the lesion plus choledochostomy produced very good late results. In patients with accidental ligation or suturing of the common bile duct, two different postoperative complications were seen: seven cases had biliary fistula and all developed benign stricture 2 years after surgery. In nine cases jaundice appeared 6 months after surgery, and a benign stricture developed in 7 of them. The most important "treatment" of these lesions is to prevent them from occurring during cholecystectomy by employing a meticulous surgical technique.

[Combined endoscopic and percutaneous transhepatic approach in postsurgical common bile duct occlusion].
UNLABELLED: Combined endoscopic and percutaneous transhepatic approach in postsurgical common bile duct occlusion. HISTORY AND CLINICAL FINDINGS: A 48-year-old patient was transferred to our hospital suffering from acute cholangitis due to complete bile duct occlusion one year after a laparoscopic cholecystectomy. Main complaints were fever over 40;C and chills, accompanied by right upper quadrant abdominal pain and jaundice. INVESTIGATIONS: Cholestastic enzymes, transaminases and leucocytes were increased. Transabdominal utrasound showed massive dilatation of the intrahepatic bile ducts. ERCP was performed and revealed a complete and impassable obstruction of the proximal common bile duct. TREATMENT AND COURSE: The bile duct occlusion following cholecystectomy was the reason for the patient inverted question marks cholangitis. Neither via ERCP nor via the percutaneous transhepatic approach was it possible to make a communication between the proximal and the distal biliary system, none of the guidewires being able to pass the obstruction. However, we finally managed to pass the obstruction in a combined endoscopic-percutaneous transhepatic rendezvous technique. The patient received a percutaneous large-calibre plastic prosthesis (Yamakawa type). 4 months after the procedure the stenosis could hardly be detected. CONCLUSION: Endoscopic treatment is successful in most patients with post-cholecystectomy bile duct strictures. Therefore, repeated surgery is usually not necessary. Even in complete bile duct occlusions, the combined endoscopic-percutaneous transhepatic method can re-open the obstruction and is therefore a possible alternative to surgery in selected cases.

A case of biliary atresia with duplication of the common bile duct.
The authors report a case of biliary atresia (BA) with duplication of the common bile duct. A 1-month-old girl was referred for investigation of persistent jaundice. BA was suspected and confirmed with intraoperative cholangiography. A portoenterostomy was performed at 50 days of age. During dissection of the fibrous remnant of the common bile duct, a separate fibrous bile duct remnant running in parallel on the left, was identified. Histologically, there was bile duct proliferation at the porta hepatis of the left bile duct remnant. A diagnosis of BA with duplicated common bile duct was made. Postoperative course was uneventful, and at a follow-up assessment at 7 months, she was jaundice free, and her progress has been unremarkable.

Three-dimensional sonographic evaluation of the common bile duct.
OBJECTIVE: To assess the accuracy of three-dimensional sonographic measurements of the common bile duct compared with standard two-dimensional anteroposterior measurement of the common duct. METHODS: Fifty-five consecutive patients referred for abdominal sonography underwent standard two-dimensional abdominal sonography followed by three-dimensional sonographic data acquisition of the right upper quadrant. A radiologist blinded to the results of the two-dimensional examination later measured the three-dimensional long axis anteroposterior common duct diameter and three-dimensional short axis anteroposterior and transverse common duct diameters. RESULTS: The mean average common duct diameter as measured by two-dimensional sonography (long axis anteroposterior) was 3.6 mm. The mean average common duct diameter as measured by long axis anteroposterior three-dimensional sonography was 4.1 mm. The mean average common duct diameter as measured by anteroposterior short axis three-dimensional sonography was 4.1 mm, and by transverse short axis three-dimensional sonography, it was 4.4 mm. The two-dimensional common duct measurement correlated with the long axis anteroposterior three-dimensional measurement (P < .001), the short axis anteroposterior three-dimensional measurement (P < .001), and the short axis transverse three-dimensional measurement (P < .005) by the Spearman rank order correlation coefficient test. CONCLUSIONS: Three-dimensional sonographic measurements of the common bile duct correlate highly with two-dimensional measurements, validating the use of three-dimensional sonography as a reliable method for evaluation of common bile duct size.

The common bile duct ligation in rat: A relevant in vivo model to study the role of mechanical stress on cell and matrix behaviour.
Common bile duct ligation leads to bile accumulation and liver fibrosis. In this model, little attention has been dedicated to the modification of the common bile duct. We have studied by histochemistry and immunohistochemistry, 3 and 5 days after ligation, the connective tissue modifications of the common bile duct wall. After bile duct ligation, compared with normal bile duct, a strong increase of the bile duct diameter, due to bile stasis, and a thickness of the bile duct wall were observed; numerous myofibroblasts expressing alpha-smooth muscle actin appeared in parallel with the detection of many proliferating connective tissue cells. These myofibroblasts secreted very early high amount of elastic fibre components, elastin and fibrillin-1. Elastic fibre increase was also observed close to the epithelial cell layer. Procollagen type III deposition was also induced 3 days after ligation but decreased thereafter, underlining that myofibroblasts modify their synthesis of extracellular matrix components to comply with the request. We show here that common bile duct ligation represents an invaluable model to study myofibroblastic differentiation and extracellular matrix adaptation produced by an acute mechanical stress.

A comparison of intraoperative ultrasound versus cholangiography in the evaluation of the common bile duct during laparoscopic cholecystectomy.
Indications for intraoperative evaluation of the common bile duct during laparoscopic cholecystectomy are controversial, as is the goal of either anatomic definition or assessing for choledocholithiasis. One hundred twenty-five consecutive patients undergoing laparoscopic cholecystectomy underwent both intraoperative ultrasound and intraoperative cholangiography. Cholangiography required slightly more time to perform; it was more sensitive (92.8% vs 71.4%) but less specific (76.2% vs 100%) for choledocholithiasis than was ultrasound. Ultrasound was somewhat more difficult to perform, and, particularly in the setting of intraabdominal obesity, was often inadequate at providing clear visualization of the intrapancreatic common bile duct. It did not provide the same anatomic definition as an adequate cholangiogram. The overall incidence of choledocholithiasis was 11.2%.

Common bile duct stones: the role of preoperative, intraoperative, and postoperative ERCP.
The indications for endoscopic retrograde cholangiopancreatography (ERCP) to demonstrate the presence of common bile duct stones has changed in the era of laparoscopic cholecystectomy. Preoperative ERCP is indicated when there is strong evidence of common bile duct stones, ie, jaundice, cholangitis, ultrasound demonstration of a common bile duct stone, and specific enzyme elevations. Preoperative ERCP is not indicated in mild gallstone pancreatitis. ERCP and endoscopic sphincterotomy as the only treatment regimen is successful in elderly patients with severe comorbid illness who have gallstones and common bile duct stones. Intraoperative ERCP does not play a role in the era of laparoscopic cholecystectomy. Transcystic common duct stone removal or laparoscopic choledochotomy is becoming the approach to common duct stones demonstrated by intraoperative cholangiography. Postoperative ERCP is indicated when intraoperative removal of common bile duct stones is unsuccessful. It is important to note that magnetic resonance cholangiography will play an increasing role and will reduce the indications and frequency of the use of ERCP.

Predictors of common bile duct stones prior to cholecystectomy: a meta-analysis.
BACKGROUND: The decision of whether or not to investigate for common bile duct stones before cholecystectomy utilizes clinical, laboratory, and radiologic information (indicators). There is tremendous individual variation among clinicians in the criteria used for making this decision. Our aim was to perform a meta-analysis of published data to estimate the performance characteristics of the most commonly used preoperative indicators of common bile duct stones. METHODS: Using predetermined exclusion criteria, we selected articles from a MEDLINE search and bibliographic review. Weighted averages were used to determine summary sensitivity, specificity, and positive and negative likelihood ratios for each indicator for stones. RESULTS: From 2221 citations identified, 22 studies met inclusion criteria. The 10 indicators examined were reported in a common fashion in three or more articles, and could be assessed preoperatively. Seven exhibited a specificity greater than 90%. Indicators with positive likelihood ratios of 10 or above were cholangitis, preoperative jaundice, and ultrasound evidence of common bile duct stones. Positive likelihood ratios for dilated common bile duct on ultrasound, hyperbilirubinemia, and jaundice ranged from almost 4 to almost 7. Elevated levels of alkaline phosphatase, pancreatitis, cholecystitis, and hyperamylasemia exhibited positive likelihood ratios of less than 3. CONCLUSIONS: This meta-analysis has identified indicators for duct stones and ranked them according to likelihood ratios. These findings can be applied as guidelines for whether to investigate for duct stones before cholecystectomy.

Management of common bile duct stones in a rural area of the United States: results of a survey.
BACKGROUND: Laparoscopic common bile duct exploration has been reported to be highly successful and cost-effective. It remains unknown to what extent the procedure is used in routine surgical practice. METHODS: We conducted a survey of general surgeons practicing in a rural area of the United States. The type of practice, laparoscopic training, performance of cholangiography, and preferred approach to choledocholithiasis were elicited. RESULTS: Sixty-eight of 207 surveys (33%) were returned. Thirty respondents (45%) indicated that they perform laparoscopic common bile duct explorations. The likelihood of laparoscopic common bile duct exploration increased with a higher number of cholecystectomies per year (p < 0.05, chi-square) but was independent of training or routine cholangiography. The preferred approach to a patient with choledocholithiasis was endoscopic retrograde cholangiopancreatography (75%), followed by laparoscopic (21%) and open exploration (4%). Reasons for not performing laparoscopic exploration were time (58%), equipment (24%), good gastrointestinal backup (6%), reimbursement (3%), increased morbidity (1.5%), lack of skill (1.5%), and other/no reason (18%). CONCLUSION: Although 45% of practicing surgeons indicated that they perform laparoscopic common bile duct explorations, only 21% practiced it as their preferred approach. Time constraints and lack of equipment are the main factors preventing the application of the laparoscopic technique toward choledocholithiasis.

[Minimally invasive treatment of common bile duct calculi].
UNLABELLED: Miniinvasive treatment of lithiasis of the common bile duct hasn't reached yet a standard end point. There are multiple techniques used for it. In this study we evaluate its indications, possibilities and limits. MATERIAL AND METHOD: In a series of 14,024 biliary patients operated over 9 years 719 patients underwent open choledocolithotomy. In 173 (1.2%) of patients we used miniinvasive procedures as follows: 71 cases underwent sequential treatment, 91 laparoscopic treatment and in 11 cases the remnant calculi were extracted 1-6 days postoperative. RESULTS: Sequential treatment was the preferred treatment when the lithiasis of the common bile duct was detected preoperative. Transcistic extraction was more often performed for the lithiasis diagnosed intraoperative. The conversion to open surgery was performed in 13 cases, remnant calculi were early diagnosed in 11 patients and late diagnosed in 14 cases (the calculi were extracted by endoscopic sphyncterotomy). All patients were healed. DISCUSSIONS: The miniinvasive procedures have to be practiced as frequently as possible because of rapid healing and early recovery of the patients, despite some disadvantage of them. The choledocotomy and choledocoduodenostomy are exceptional techniques to be used in specific cases.

Adaptive hepatic changes in mild stenosis of the common bile duct in the rat.
Adaptive hepatic changes were investigated in rats with mild stenosis of the common bile duct and in sham-operated controls. The studies were performed 24 h and 7-12 days postoperatively. A continuous intravenous infusion of taurocholic acid at stepwise-increasing rates was performed to explore the responses to bile acid effects. During the infusion, bile flow and the outputs of bile acids, phospholipids, cholesterol, alkaline phosphatase and gamma glutamyl transpeptidase were studied. At the end of the infusion, hepatic morphometric measurements were performed. In other experimental sets, biliary excretions of horseradish peroxidase, a marker of microtubule-dependent vesicular transport in the hepatocyte, and sulphobromophthalein, a well-known organic anion model, were studied. In other rats, bile acid pool size and composition were determined by depletion of bile. The results in rats with mild stenosis maintained for 24 h showed a greater susceptibility to the toxicity of taurocholic acid, as revealed by the abrupt decrement in bile flow at high rates of infusion, and increased outputs of phospholipids and canalicular enzymes. Conversely, rats with mild stenosis maintained for 7-12 days showed decreased bile acid maximum secretory rate and biliary outputs of phospholipids and canalicular enzymes, as well as hepatocyte hypertrophy. These findings may explain the limited hepatic and systemic repercussion of experimental mild stenosis of the common bile duct and help us to understand the early stages of constriction of the common bile duct in man.

Papillary adenoma of the distal common bile duct.
A 73-year-old man with a papillary adenoma located in the distal common bile duct is reported. He underwent pylorus-preserving pancreatoduodenectomy. The lesion in the common bile duct featured papillary proliferation of the epithelium and fibrous elements with diffuse infiltration by inflammatory cells. Positive staining for MIB-1 (Ki-67) and p53 was identified in the nuclei of the proliferative epithelium. These findings suggested the malignant potential of this lesion. Further progress in imaging diagnostic techniques should increase the frequency with which such lesions are discovered. Even now, if mural irregularities and defects are found in the extrahepatic biliary system, especially the distal common bile duct, the possibility of such borderline biliary adenoma should be taken into consideration when making a diagnosis.

Jaundice in patients with acute cholecystitis. Its validity as an indication for common bile duct exploration.
Our study demonstrates that (1) mild to moderate jaundice is frequently seen in patients with acute cholecystitis; (2) severe degrees of jaundice were seen in two patients without the presence of common duct stone or recognizable obstruction of the common bile duct; (3) only one of forty-one patients with acute cholecystitis had common bile duct stone; (4) jaundice does not appear to be a compelling reason for choledochotomy; and (5) less invasive technics such as intravenous and intraoperative cholangiography should suffice to exclude the possibility of common bile duct stone in patients with acute cholecystitis.

[Common bile duct cyst of type 1].
A case of common bile duct cyst, type 1, is presented. On account of the risk of development of cancer, excision of the cyst and the gall bladder is recommended. The duct system is then reestablished by means of hepato-jejunostomy. Scandinavian gastroenterologists should bear this condition im mind in patients of Asiatic origin with signs of biliary disease.

Effect of cholecystectomy for gallstones on the surface of the papilla of Vater and the diameter of the common bile duct.
BACKGROUND AND STUDY AIMS: To date, little is known about changes in the size of the papilla of Vater in patients with gallstones. Most of the research concerning these patients has investigated changes in the diameter of the common bile duct and pressure in the sphincter of Oddi region. The latest research has not confirmed the prevalent opinion that the common bile duct dilates after cholecystectomy; moreover, knowledge about changes in the form and size of the papilla of Vater remains poor. The aim of our research was to measure the surface of the papilla of Vater and the diameter of the periampullary pancreatic part of the common bile duct before surgery, then 3 months and 6 months after surgery, using endoscopic ultrasound. PATIENTS AND METHODS: In patients with symptomatic gallstones but with no evidence of cholestasis or stones in the common bile duct, the surface of the papilla of Vater and the diameter of the periampullary pancreatic part of the common bile duct were measured before surgery by endoscopic ultrasound. In the postoperative period, measurements were repeated in patients with an early occurrence of nausea, distension, bloating and pain in the upper abdomen and in patients without any symptoms in the same time period. The surface of the normal papilla of Vater and the diameter of the periampullary pancreatic part of the common bile duct were determined in healthy subjects. RESULTS: In all the patients included in our study, the surface of the papilla of Vater was enlarged before surgery and, after 3 months, was even larger. However, after 6 months, it was practically the same as before surgery. The diameter of the periampullary pancreatic part of the common bile duct before surgery and 6 months after surgery was within normal limits. However, a statistically significant and transient increase in the diameter was noticed in the third month after cholecystectomy. The results were almost the same for symptomatic and asymptomatic patients. CONCLUSION: In patients with symptomatic gallstones, the surface of the papilla of Vater is increased while the diameter of the periampullary pancreatic part of the common bile duct is normal. Cholecystectomy is an intervention that causes an additional transient increase in the surface of the papilla of Vater and a transient increase in the diameter of the periampullary pancreatic part of the common bile duct. The surface of the papilla of Vater does not reach normal values but the diameter of the periampullary pancreatic part of the common bile duct is normalized 6 months after surgery. There is no relation between clinical disorders and changes in the morphology of the papilla of Vater and the periampullary pancreatic part of the common bile duct after cholecystectomy.
