The role of therapeutic endoscopy associated with extracorporeal shock-wave lithotripsy and bile acid treatment in the management of Caroli's disease

ERCP for treatment of Caroli's disease complicated with biliary infection: A case report and review of the literature

BACKGROUND

Caroli's disease is a rare congenital malformation characterized by saccular dilatation of intrahepatic bile ducts, with intrahepatic stones and recurrent cholangitis being its potential complications, which can lead to sepsis as a life-endangering complication. Surgery is mostly used for Caroli's disease complicated with biliary infection; however, the morbidity and mortality of surgery are high during the acute infectious period.

CASE SUMMARY

A middle-age male patient presented with epigastric pain and fever for 11 h. He was diagnosed with Caroli's disease 11 years ago, and he had acute biliary infection every 6 to 10 mo since then, which usually recovered after conservative treatments. Upon admission, he was initially given conservative treatment. However, he still had fever and acute biliary infection. We performed endoscopic retrograde cholangiopancreatography (ERCP) after failed conservative treatment, and the patient recovered uneventfully.

CONCLUSION

For patients with Caroli's disease complicated with biliary infection who failed to conservative treatment, ERCP is a safe, feasible, and effective treatment method.

Using cholecystokinin to facilitate endoscopic clearance of large common bile duct stones

AIM: To evaluate the effect of cholecystokinin (CCK) during extracorporeal shockwave lithotripsy (ESWL) in the clearance of common bile duct (CBD) stones in endoscopic retrograde cholangiopancreatography (ERCP).

METHODS: Between January 2007 and September 2012, patients with large CBD stones who were treated with ESWL and ERCP were identified retrospectively. Patients were randomized in equal numbers to cholecystokinin (CCK) and no CCK groups. For each CCK case, a dose (3 ng/kg per min for 10 min) of sulfated octapeptide of CCK-8 was administered intravenously near the beginning of ESWL. ERCP was performed 4 h after a session of ESWL. The clearance rate of the CBD was assessed between the two groups.

RESULTS: A total of 148 consecutive cases (CCK group: 74, no CCK group: 74) were tallied. Overall there were 234 ESWLs and 228 ERCPs in the 148 cases. The use of CCK showed a significantly higher rate of successful stone removal in the first ESWL/ERCP procedure (71.6% vs 55.4%, P = 0.035), but resulted in similar outcomes in the second (42.8% vs 39.4%) and third (41.7% vs 40.0%) sessions, as well as total stone clearance (90.5% vs 83.8%). The use of mechanical lithotripsy was reduced in the CCK group (6.8% vs 17.6%, P = 0.023), and extremely large stone (≥ 30 mm) removal was higher in the CCK group (72.7% vs 41.7%, P = 0.038).

CONCLUSION: CCK during ESWL can aid with the clearance of CBD stones in the first ESWL/ERCP session. Mechanical lithotripsy usage was reduced and the extremely large stone (≥ 30 mm) clearance rate can be raised.

Surgical management of congenital intrahepatic bile duct dilatation, Caroli's disease and syndrome: long-term results of the French Association of Surgery Multicenter Study

OBJECTIVE

To assess clinical presentation and long-term results of surgical management of congenital intrahepatic bile duct dilatation (IHBDD) (Caroli disease and syndrome) in a multicenter setting.

BACKGROUND

Congenital IHBDD predisposes to biliary stasis, resulting in intrahepatic lithiasis, septic complications, and cholangiocarcinoma. Although liver resection (LR) is considered to be the treatment of choice for unilobar disease extent into the liver, the management of bilobar disease and/or associated congenital hepatic fibrosis remains challenging.

METHODS

From 1978 to 2011, a total of 155 patients (median age: 55.7 years) were enrolled from 26 centers. Bilobar disease, Caroli syndrome, liver atrophy, and intrahepatic stones were encountered in 31.0%, 19.4%, 27.7%, and 48.4% of patients, respectively. A complete resection of congenital intrahepatic bile ducts was achieved in 90.5% of the 148 patients who underwent surgery.

RESULTS

Postoperative mortality was nil after anatomical LR (n = 111) and 10.7% after liver transplantation (LT) (n = 28). Grade 3 or higher postoperative morbidity occurred in 15.3% of patients after LR and 39.3% after LT. After a median follow-up of 35 months, the 5-year overall survival rate was 88.5% (88.7% after LT), and the Mayo Clinic score was considered as excellent or good in 86.0% of patients. The 1-year survival rate was 33.3% for the 8 patients (5.2%) who presented with coexistent cholangiocarcinoma.

CONCLUSIONS

LR for unilobar and LT for diffuse bilobar congenital IHBDD complicated with cholangitis and/or portal hypertension achieved excellent long-term patient outcomes and survival. Because of the bad prognosis of cholangiocarcinoma and the sizeable morbidity-mortality after LT, timely indication for surgical treatment is of major importance.

Current management of noninfectious hepatic cystic lesions: A review of the literature

Nonparasitic hepatic cysts consist of a heterogeneous group of disorders, which differ in etiology, prevalence, and manifestations. With improving diagnostic techniques, hepatic cysts are becoming more common. Recent advancements in minimally invasive technology created a new Era in the management of hepatic cystic disease. Herein, the most current recommendations for management of noninfectious hepatic cysts are described, thereby discussing differential diagnosis, new therapeutic modalities and outcomes.

Bile duct cyst in adults: interventional treatment, resection, or transplantation?

Cystic dilatations of the bile ducts may be found along the extrahepatic biliary tree, within the liver, or in both of these locations simultaneously. Presentation in adults is often associated with complications. The therapeutic possibilities have changed considerably over the last few decades. If possible, complete resection of the cyst(s) can cure the symptoms and avoid the risk of malignancy. According to the type of bile duct cyst, surgical procedures include the Roux-en-Y hepaticojejunostomy and variable types of hepatic resection. However, the diffuse forms of Todani type V cysts (Caroli disease and Caroli syndrome) in particular remain a therapeutic problem, and liver transplantation has become an important option. The mainstay of interventional treatment for Todani type III bile duct cysts is via endoscopic retrograde cholangiopancreatography. The diagnostic term "bile duct cyst" comprises quite different pathological and clinical entities. Interventional therapy, hepatic resection, and liver transplantation all have their place in the treatment of this heterogeneous disease group. They should not be seen as competitive treatment modalities, but as complementary options. Each patient should receive individualized treatment after all of the clinical findings have been considered by an interdisciplinary team.

Caroli's disease: report of surgical options and long-term outcome of patients treated in Argentina. Multicenter study

BACKGROUND

Caroli's disease (CD) management is still controversial.

AIM

The purpose of this study is to report the most frequent clinical features, treatment options, and outcome obtained after surgical management of CD.

METHODS

A voluntary survey was conducted. Demographic, clinical, surgical, and pathological variables were analyzed.

RESULTS

Six centers included 24 patients having received surgical treatment from 1991 to 2009. Seventeen (70.8%) patients were female, with average age of 48.7 years old (20-71), and 95.5% were symptomatic. There was left hemiliver involvement in 75% of the patients. Surgical procedures included nine left lateral sectionectomies, eight left hepatectomies, and four right hepatectomies for those with hemiliver disease, while for patients with bilateral disease, one right hepatectomy and two Roux-en-Y hepaticojejunostomies were performed. The average length of hospitalization was 7 days. For perioperative complications (25%), three patients presented minor complications (types 1-2), while major complications occurred in three patients (type 3a). No mortality was reported. After a median follow-up of 166 months, all patients are alive and free of symptoms. CD diagnosis was confirmed by histology. Congenital hepatic fibrosis was present in two patients (8.3%) and cholangiocarcinoma in one (4.2%).

CONCLUSIONS

CD in Argentina is more common in females with left hemiliver involvement. Surgical resection is the best curative option in unilateral disease, providing long-term survival free of symptoms and complications. In selected cases of bilateral disease without parenchymal involvement, hepaticojejunostomy should be proposed. However, a close follow-up is mandatory because patients might progress and a transplant should be indicated.

Long-term outcome of liver resection and transplantation for Caroli disease and syndrome

OBJECTIVE

To assess the preoperative disease characteristics as well as the rate of postoperative complications, patient survival, and course of symptoms after liver resection or orthotopic liver transplantation (OLT) for Caroli disease (CD) or syndrome (CS).

SUMMARY BACKGROUND DATA

The clinical course of monolobar or diffuse CD or CS is often characterized by multiple conservative treatment attempts and interventions with recurrent episodes of cholangitis and a serious reduction in quality of life. The role and effectiveness of surgical treatment is still not well defined.

PATIENTS AND METHODS

Between June 1989 and December 2002, we treated 44 consecutive patients with CD or CS who had failure of conservative treatment before and were referred for surgical intervention. Demographic and clinical data, operative procedures and related morbidity, course of symptoms, and long-term follow-up were reviewed. Four patients with palliative resection for cholangiocarcinoma and incidental diagnosis of CD were excluded from the analysis.

RESULTS

Twenty-two women and 18 men had a median period of 26.5 months from onset of symptoms to surgical therapy. Their median age at therapy was 49 years and 80% of the patients had monolobar disease with a left-right ratio of 2.6 to 1. Thirty-three (82.5%) patients underwent liver resection, while 4 (10%) patients received OLT for diffuse disease. Biliodigestive anastomosis alone was performed in 3 (7.5%) patients with contraindications to OLT. Patients (37.5%) had minor postoperative complications, which were treated conservatively, while 2 (5%) transplanted patients had a reoperation due to intraperitoneal bleeding. After a median follow-up of 86.5 months, we observed a favorable patient and graft survival. Three deaths during follow-up were not related to treatment or disease complications. Follow-up of disease-related symptoms, biliary complications, and antibiotic treatment revealed a significant improvement.

CONCLUSION

Our data show that liver resection for monolobar CD or CS and OLT for diffuse manifestations can achieve excellent long-term patient survival with marked symptom relief. Because of life-threatening long-term complications such as biliary sepsis and development of cholangiocarcinoma, timely indication for surgical treatment is crucial.

Congenital intrahepatic bile duct dilatation is a potentially curable disease: long-term results of a multi-institutional study

OBJECTIVE

To report clinical presentation, perioperative outcome, and long-term results of surgical management of congenital intrahepatic bile duct (IHBD) dilatations (including Caroli disease) in a multi-institutional setting.

SUMMARY BACKGROUND DATA

Congenital IHBD dilatations are a rare congenital disorder predisposing to intrahepatic stones, cholangitis, and cholangiocarcinoma. The management remains difficult and controversial for bilobar forms of the disease or when concurrent congenital hepatic fibrosis is associated.

METHODS

From 1976 to 2004, 33 patients (range 11 to 79 years) were retrospectively enrolled. Disease extent into the liver was unilobar in 26 patients and bilobar in 7 patients (21%). Cholangiocarcinoma, congenital hepatic fibrosis, and intrahepatic stones were present in 2, 10, and 20 patients, respectively. Transplantations or liver resections were performed in 5 and 27 patients, respectively, whereas 1 asymptomatic patient was managed conservatively.

RESULTS

Postoperative mortality was nil. Postoperative complications occurred in 16 of 32 operated patients (50%) and additional procedures for residual stones were required in 5 patients. During a median follow-up of 80 months (1 patient being lost for follow-up) no patient developed metachronous carcinoma. Six patients (30%) developed recurrent intrahepatic stones but satisfactory late outcome was achieved in 27 patients (87%).

CONCLUSIONS

Partial or total liver resection achieves satisfactory late outcome in congenital IHBD dilatations, when the affection is treated at an early stage and when the extent of liver resection is tailored to intrahepatic disease extent and takes into consideration the presence and severity of underlying chronic liver and renal diseases.

Caroli's disease: identification and treatment strategy

Caroli's disease is a rare congenital disease of the liver characterized by cystic dilation of the intrahepatic bile duct. Classic Caroli's disease involves malformations of the biliary tract alone, whereas Caroli's syndrome refers to the presence of associated congenital hepatic fibrosis. Caroli's disease usually presents during childhood and early adulthood. The clinical features of Caroli's disease include jaundice, right upper abdominal pain, and fever due to the associated complications of hepatolithiasis or bacterial cholangitis. Endoscopic or percutaneous cholangiography is the traditional method of diagnosis, but magnetic resonance cholangiopancreatography is emerging as the diagnostic modality of choice. The treatment for Caroli's disease includes supportive care with antibiotics for cholangitis and ursodeoxycholic acid for hepatolithiasis. Surgical resection has been used successfully in patients with monolobar disease. For patients with diffuse involvement, the treatment of choice is orthotopic liver transplantation.

The role of surgery in Caroli's disease

BACKGROUND

Caroli's disease is a rare congenital disorder characterized by multifocal segmental dilation of the intrahepatic bile ducts. Whether conservative or surgical strategies should be preferred is still a matter of debate. The aim of this study was to evaluate the role of surgery in the management of Caroli's disease.

STUDY DESIGN

From April 1998 until August 2005, 12 consecutive patients with Caroli's disease were treated in the Department of General, Visceral, and Transplantation Surgery, University Hospital Essen, Germany. All patients were intended to receive liver resections or liver transplantations.

RESULTS

There were seven men and five women, with a median age of 39 years (range 7 months to 70 years). Eight patients had monolobar and four patients had bilobar liver involvement. All patients had a history of recurrent cholangitis, with up to 16 unsuccessful conservative treatment attempts. Nine patients (75%) underwent liver resection and two (17%) had liver transplantation. Intraoperatively, three patients (25%) were found to have cholangiocarcinoma, of which one was unresectable. There was no mortality and only low morbidity (16%) postoperatively. After a median followup of 31 months, 11 patients are well with no recurrent symptoms.

CONCLUSIONS

Surgery can offer a definite therapy, with an acceptable morbidity and virtually no mortality in localized Caroli's disease. In diffuse disease, the use of extended resections or liver transplantation can provide good longterm results.

The hepatic fibrocystic diseases

The hepatic fibrocystic diseases present with variable intrahepatic biliary abnormalities, which range from portal tract enlargement and fibrosis to cystic formations. They may present as autosomal recessive or dominant polycystic kidney diseases, with associated dilatation of the renal collecting system, or as incompletely characterized cystic diseases. Symptoms from the liver disease often result from complications of fibrosis or dilated ducts/cyst (sludge, lithiasis, infection). The treatment is supportive, with careful attention to associated renal disease. Liver transplantation is an option in selected patients.

Caroli's disease: Liver resection and liver transplantation. Experience in 33 patients

BACKGROUND

The aim of this study was to review and discuss our observations on 33 patients who underwent surgical treatment for Caroli's disease (CD), focusing on diagnosis, current surgical management, and long-term outcome.

METHODS

Between May 1993 and June 2004, 642 liver resections and 286 liver transplantations in 252 patients were performed in our department of surgery. Thirty-three patients were referred to our center for diagnostic and therapeutic management of CD. Prior surgical interventions for hepatobiliary disorders, current diagnostic and surgical procedures, procedure-specific complications, duration of hospital stay, duration of follow-up, outpatient information, and long-term outcome were reviewed.

RESULTS

Fifteen male and 18 female patients were treated in this study. Initial symptoms and signs of the disease noted in our patients included right upper quadrant pain, fever, and jaundice. In 2 of the 33 patients, we noted clinical evidence of cirrhosis followed by histologic confirmation. One patient suffered from variceal bleeding. In 26 patients, diagnoses were established by a combined endoscopic retrograde cholangiopancreatography, ultrasonography, and computed tomographic studies. The disease was localized in 25 and diffuse in 8 patients. Liver resection was carried out in 29 patients. Partial hepatectomies were performed in 27 of these 29 at our institution. Two female patients with the diffuse disease underwent orthotopic liver transplantation. Thirteen of the 31 patients who underwent surgery at our institution had an uneventful postoperative course. Fourteen patients had minor postoperative complications and responded well to medical management. Four patients had major complications that required further surgical treatment. Two patients died of complications related to postoperative hemorrhage and sepsis. Two patients with intrahepatic cholangiocarcinoma died because of primary tumor progress. One patient with cholangiocarcinoma died 1 year after a successful left hepatectomy because of metastatic disease recurrence. The long-term results of the 26 surviving patients were assessed during a mean follow-up of 3.7 years (range, 1-11 years). All 26 patients remained free of biliary symptoms or complications. In 25 patients, surgery including liver transplantation was curative.

CONCLUSIONS

Partial hepatectomy for localized CD is potentially curative. In patients with diffuse CD, liver transplantation provides gratifying long-term results.

Extracorporeal shock wave lithotripsy for clearance of bile duct stones resistant to endoscopic extraction

BACKGROUND

Endoscopic extraction of bile duct stones after sphincterotomy has a success rate of up to 95%. Failures occur in patients with extremely large stones, intrahepatic stones, and bile duct strictures. This study examined the efficacy and the safety of extracorporeal shock-wave lithotripsy in a large cohort of patients in whom routine endoscopic measures including mechanical lithotripsy had failed to extract bile duct stones.

METHODS

Out of 1587 consecutive patients, endoscopic stone extraction including mechanical lithotripsy was unsuccessful in 313 (20%). These 313 patients (64% women, median age, 73 years) underwent high-energy extracorporeal shock-wave lithotripsy. Stone targeting was performed fluoroscopically (99%) or by ultrasonography (1%).

RESULTS

Complete clearance of bile duct calculi was achieved in 281 (90%) patients. In 80% of the patients, the fragments were extracted endoscopically after shock-wave therapy; spontaneous passage was observed in 10%. For patients with complete clearance compared with those without there were no differences with regard to size or number of the stones, intrahepatic or extrahepatic stone location, presence or absence of bile duct strictures, or type of lithotripter. Cholangitis (n = 4) and acute cholecystitis (n = 1) were the rare adverse effects.

CONCLUSIONS

In patients with bile duct calculi that are difficult to extract endoscopically, high-energy extracorporeal shock-wave lithotripsy is a safe and effective therapy regardless of stone size, stone location, or the presence of bile duct stricture.
