Reoperations of the extrahepatic bile ducts

The results of reoperations on the extrahepatic bile ducts in 82 patient s performed, mainly, for undetected and uncorrigated changes in the extrahepatic bile ducts caused by diagnostic, tactical and technical errors made during the first operation are presented.     

Congenital dilatation of the bile ducts

Our experience with five cases of cystic dilatation of the extrahepatic bile ducts is reported and compared with the literature. The following conclusions have been reached: (1) The etiology of this anomaly is primarily congenital but may involve an acquired component. (2) Diagnosis should be suspected when any of the triad of abdominal pain, right upper quadrant mass, or jaundice is present. (3) The diagnosis can usually be made in infants based on the clinical picture and routine radiologic studies. (4) Retrograde cholangiopancreatography is a useful tool in making the diagnosis in older children and adults. (5) Roux-en-Y choledochocystojejunostomy is the procedure of choice for type I cysts, excision for type II, and choledochocystoduodenostomy for type III.     

Surgical treatment of intraoperative injuries and cicatricial strictures of extrahepatic bile ducts

The analysis of 70 cases of surgical treatment for intraoperative injuries and cicatricial strictures of extrahepatic bile ducts was carried out. In 25 patients surgical procedure was restorative and in 45--reconstructiver. Most common causes of corrective operations were: iatrogenic injuries of extrahepatic bile ducts (14) and cicatricial strictures of hepaticocholedochal duct due to intraoperative trauma (31). The problems of operative technique in performing biliobilio-, hepato-hepatico and hepatico-jejuno-anastomoses are considered. There were three deaths in the early postoperative period: 2 patients died of hepatic failure, pyogenic cholangiogenic intoxication caused by cholangioectasies and intrahepatic abscesses, and 1-due to generalyzed peritonitis caused by acute gastric ulcer perforation. Special attention is paid to the choice of the method of prolonged drainage used in reconstructive as well as in restorative operations.     

Prognostic factors and management of carcinomas of the gallbladder and extrahepatic bile ducts

Cancers of the biliary tract are uncommon but aggressive malignancies that pose difficult problems in diagnosis and management. Long-term survival with these cancers is limited by their propensity for local invasion, so that pathologic stage becomes a major prognostic factor, and by their ability to cause biliary obstruction and sepsis and interfere with hepatic function. In selected patients, surgical resection offers the possibility of cure, but effective palliation is often the principal goal of treatment. Radiologic and endoscopic modalities thus often play a major role in patient management.     

Hepatocellular carcinoma presenting as a tumour of the hilar and extrahepatic bile ducts

A case of hepatocellular carcinoma extending within the large extra- and intrahepatic bile ducts is reported. No primary tumour was found in the liver parenchyma by abdominal ultrasound, spiral computed tomography or magnetic resonance, but transduodenal cholangioscopy showed tumour in the common hepatic ducts and the two main branches. Endoscopic biopsy showed highly differentiated hepatocellular carcinoma. The patient was treated with endoscopic biliary drainage and died at home 7 months after admittance.     

Carcinoma of the extrahepatic bile ducts. The University of California at San Francisco experience

OBJECTIVE: The authors investigated the combined experience of a single institution in treating bile duct carcinoma during the modern era. SUMMARY BACKGROUND DATA: Bile duct carcinomas are notoriously difficult to cure, with locoregional recurrence the rule, even after radical resection. Adjuvant efforts have included various radiation modalities, with limited success. Recently, charged-particle radiotherapy has also been used in these patients. METHODS: The authors performed a retrospective chart analysis of 129 patients with bile duct adenocarcinomas treated between 1977 and 1987 through the University of California at San Francisco, including 22 patients treated at Lawrence Berkeley Laboratory with the charged particles helium and neon. The minimum follow-up was 5 years. Survival, outcome, and complication results were analyzed. RESULTS: Sixty-two patients were treated with surgery alone (S), 45 patients received conventional adjuvant x-ray radiotherapy (S + X), and 22 were treated with charged particles (S + CP). The median survival times were 6.5, 11, and 14 months, respectively, for the entire group, and 16, 16, and 23 months in patients treated with curative intent. There was a survival difference in patients undergoing total resection compared with debulking (p = 0.05) and minor resections (p = 0.0001). Patients with microscopic residual disease had increased median survival times when they were treated with adjuvant irradiation, most markedly after CP (p = 0.0005) but also with conventional X (p = 0.0109). Patients with gross residual disease had a less marked but still statistically significant extended survival (p = 0.05 for S + X and p = 0.0423 for S + CP) after irradiatio CONCLUSIONS: The mainstay of bile duct carcinoma management was maximal surgical resection in these patients. Postoperative radiotherapy gave patients with positive microscopic margins a significant survival advantage and may be of value in selected patients with gross disease.     

Cystic dilation of extrahepatic bile ducts in adulthood: diagnosis, surgical treatment and long-term results

To evaluate the long-term results of surgery for choledohal cyst in adulthood, a series of 13 patients over the age of 16 operated on for choledochal cyst during a period of six years and followed-up for a minimum of 3 years was analyzed. Patients with type I and IVa cysts underwent extrahepatic cyst resection and Roux-en-Y hepatico-jejunostomy. Choledochoceles (type III) were managed endoscopically. No operative mortality or morbidity occurred. Type I and III cysts showed almost ideal follow-up with no sign of stricture on HIDA scan. One type IVa cyst patients developed recurrent cholangitis due to anastomotic stricture, managed percutaneously. Whenever possible, complete cyst resection and Roux-en-Y reconstruction is the treatment of choice for all extrahepatic biliary cysts. Intra- and extrahepatic dilatations are adequately treated by extrahepatic resection and careful endoscopic or radiologic surveillance. Small choledochoceles can be safely managed by endoscopic sphincterotomy.     

Congenital hepatic fibrosis with dilation of intrahepatic bile ducts. A therapeutic approach

A case of congenital hepatic fibrosis with dilation of the intrahepatic ducts is presented. External drainage and lavage of the biliary tract through a prosthetic "Y" tube and internal drainage accomplished by a Roux en-Y cholangiojejunostomy resulted in prevention of the patient's recurrent bouts of cholangitis and sepsis. Surgical therapy for recurrent cholangitis in this disease is reviewed.     

Congenital cystic dilation of the bile duct associated with Laurence-Moon-Biedl-Bardet syndrome

We describe a 26-year-old man in whom the Laurence-Moon-Biedl-Bardet syndrome had been associated with congenital cystic dilations of both the intrahepatic and extrahepatic biliary tract. The fact of the simultaneous occurence of two rare diseases in a single patient suggests the congenital origin of cystic dilation of the biliary tract and the importance of examining for a possible association of anomalies in the alimentary tract with the Laurence-Moon-Biedl-Bardet syndrome.     

Intraductal ultrasound of the bile ducts

Intraluminal ultrasound with 12.5 and 20 MHz transducer allows precise analysis of the extrahepatic bile ducts and the adjacent structures. Inflammatory and malignant thickening of the bile duct wall can be assessed without difficulty. It is not possible, however, to differentiate between benign and malignant bile duct thickening, and for this purpose biopsy is required in addition. In tumor staging intraluminal ultrasound is superior to conventional ultrasound, because tumor infiltration into the adjacent tissues can be assessed and lymph nodes along the hepaticoduodenal ligament can be detected. Owing to the ultrasound frequencies available, local staging is limited to a circumference of 1.5/2 cm. Intraluminal ultrasound provides additional information that is useful in the diagnosis and therapy of bile duct stones and in different types of palliative tumor therapy. The procedure is simple and not too time consuming, and it involves no risks to the patient.     

Primary lithiasis of the bile ducts

An analysis is made of 24 cases of primitive lithiasis of the biliary tracts, viz; 10 of diffuse intrahepatic lithiasis, 9 of intrahepatic lithiasis localized in one of the ducts; and 5 of extrahepatic lithiasis. The most common cause were stenosis (14 cases) generally of idiopathic or congenital nature, followed by those of iatrogenic or tumoral origin. There were also cases of isolated or diffuse anomalus dilatation of the biliary ducts. A lithogenetic bile as well as infectious processes are rather considered secondary factors. The diagnosis of the real nature of the condiction was usually established in the postoperative period, this being an explanation why repeated surgery was so common (75%). There was a high postoperative mortality in the diffuse forms owing to severe manifestations of biliary sepsis perpetuated by the stones. Depending upon the individual cases the following procedures are proposed: 1) Biliodigestive anastomosis 2) Sphinteropapilloplasty 3) Dilatation and calibration of the stenosis 4) Postoperative instrumental extraction of calculi. The last-named procedure was carried out in 58% of the cases and result in an improvement in the serious prognosis. Primitive lithiasis should always be borne in mind when undertaking surgery of the biliary tracts in order to avoid additional surgery.     

Topometry of normal intrahepatic bile ducts

This paper focuses on practical problems which may also prove to be of theoretical importance, by presenting a method of establishing an exact topometry of the intrahepatic bile ducts. Measurements were made on corrosive casts of the intrahepatic bile ducts from 13 human livers. On the basis of the topometric results presented it is possible to construct an adequate model by means of plastic tubes and to use it for the study of bile flow.     

Serum bile acids and ursodeoxycholic acid treatment in cystic fibrosis-related liver disease

Increased circulating levels of hepatotoxic bile acids may contribute to the cholestasis characteristic of cystic fibrosis-related liver disease. The aims of this study were to compare serum bile acid profiles in patients with cystic fibrosis with and without liver disease, and to evaluate the effect of treatment with ursodeoxycholic acid, a non-hepatotoxic bile acid, on liver biochemistry and serum bile acids in patients with cystic fibrosis-related liver disease. Fasting and postprandial serum bile acid levels were analysed in 15 patients (nine males; median age 18 years) with cystic fibrosis-related liver disease and compared with serum bile acid levels in 18 cystic fibrosis patients (12 males; median age 22 years) without liver disease and 10 control subjects. Fasting and postprandial serum levels of primary and secondary serum bile acids were analysed using high-performance liquid chromatography. Liver biochemistry and serum bile acids were measured in six cystic fibrosis patients with liver disease before and 6 months after treatment with ursodeoxycholic acid 20 mg/kg/day and compared with six control patients with cystic fibrosis-related liver disease. Total fasting and postprandial serum bile acid levels were significantly (P < 0.01) elevated in patients with liver disease compared to those without liver disease and controls. The fasting glycine conjugates of cholic acid, chenodeoxycholic acid and deoxycholic acid, and the fasting and postprandial taurine conjugates of cholic acid and chenodeoxycholic acid were significantly (P < 0.05) elevated in liver disease patients compared to patients without liver disease and controls. After 6 months' treatment with ursodeoxycholic acid, although the serum was significantly saturated with ursodeoxycholic acid and significant improvements in liver biochemistry were observed in the treatment group, there was no significant reduction in the levels of individual serum bile acids. Although circulating levels of potentially hepatotoxic serum bile acids are elevated in patients with cystic fibrosis-related liver disease, improvements in liver biochemistry associated with ursodeoxycholic acid treatment cannot be attributed solely to alterations in levels of endogenous bile acids.     

Surgical treatment of extrahepatic bile duct carcinoma

OBJECTIVE: To evaluate the experience in the diagnosis and surgical treatment of the extrahepatic bile duct carcinomas. METHODS: 242 patients with extrahepatic bile duct carcinoma over the past 20 years was retrospectively studied. RESULTS: The origin points were carcinomas of the upper bile duct in 168, of the middle bile duct in 18, and of the lower bile duct in 56 patients. The preoperative diagnostic rates for the location and the nature of the lesion were respectively raised to 97.2% and 94.5% by combination of ultrasonography and CT. The curative resection rates for the tumors in the upper, middle, and lower bile duct over the recent five years reached to 50.0%, 50.0% and 71.4%. respectively. Follow-up of patients with curative resection showed a one year recurrent rate of 73.9% and a three year recurrent rate of 100.0% with a mean recurrent time of 9.6 months in patients with local metastasis, in contrast to 13.3%, 71.4% and 17.5 months in those without metastasis. Metastasis was mainly responsible for the recurrence. Liver or multiple organ failure, intra-abdominal infection and gastrointestinal hemorrhage were the common and serious complications. CONCLUSION: The case number of the bile duct carcinoma presented a remarkable increment tendency. Ultrasonography and CT were satisfactory enough for diagnosis. To reduce the recurrent rate, resection of the tumor together with the lymph, nervous, fatty and connective tissues in the hepatic hilus, even the right celiac ganglia, should be considered the necessary procedure. Monitoring and protecting the main organs to prevent the multiple organ failure, controlling the gastrointestinal hemorrhage and the intra-abdominal infection are important to decreasing the mortality.
