Treatment of postcholedochoduodenostomy symptoms.

Upper abdominal symptoms after side-to-side choledochoduodenostomy (CDDY) may be attributed to stagnant bile, food and calculi pooling in the distal bile duct 'sump' with resultant biliary or pancreatic duct obstruction and sepsis. Endoscopic sphincterotomy (ES) provides a means of draining this sump. The aim of this study was to assess outcome following endoscopic retrograde choledochopancreatography (ERCP) and ES in patients with post-CDDY symptoms. Eight such patients (M: F = 1:7) underwent ERCP between September 1981 and March 1987. Their median age was 60 years (range: 37-72 years) and the median period since CDDY was 11 years (range: 1-28 years). The median follow-up after ERCP was 18 months (range: 14-94 months). Presenting symptoms comprised postprandial (one) or intermittent (seven) abdominal pain, cholangitis (three), pancreatitis (one) and jaundice (one). ERCP revealed bile duct abnormalities in four, consisting of filling defects alone (two), anastomotic narrowing with filling defects (one) and sclerosing cholangitis. ES was performed in seven, of whom three (all with filling defects at ERCP) remain asymptomatic and three are significantly improved. One had recurrent pancreatitis for which a sphincteroplasty and pancreatic duct septectomy was performed. ES was not performed in one because of technical difficulties (there being no subsequent improvement). It is concluded that, in patients with post-CDDY biliary symptoms, endoscopic sphincterotomy relieves the symptoms by either producing drainage of the sump at the distal bile duct, or dividing a dysfunctioning sphincter of Oddi.

Palliation of malignant jaundice.

The great majority--perhaps 90%--of patients with malignant jaundice can only be treated by palliative means. The best method of palliation is yet to be defined. Some groups advocate routine surgical bypass, while others hold that all cases should be managed by the insertion of stents, either endoscopically or percutaneously. Recovery from surgery consumes a significant portion of residual lifespan, while stents produce long-term morbidity from stent blockage and cholangitis. The present study used a convenient and simple method to quantify the quality of life that follows surgical bypass and stent insertion. Six patients were followed for at least 6 months after open bypass, and nine after stent insertion. Four patients in each group were still alive at 12 months. The study suggests that there is no significant difference in the quality of life obtained by either method at 6 months, but that there is a clear-cut advantage in having surgical bypass by 12 months. The study points to the need to evolve better stents, to improve stent management and to define criteria which will identify patients who are likely to survive more than 6 months.

Iatrogenic injuries to the extrahepatic biliary tract.

Iatrogenic injuries to the extrahepatic biliary tract continue to occur and result in significant morbidity. Over the last 10 years, 26 patients have been referred to Westmead Hospital for management of iatrogenic biliary tract injuries. Of these injuries, 22 occurred during cholecystectomy, three during hepatectomy and one during a pancreaticoduodenectomy. The principles of avoidance and repair are discussed. It is concluded that these injuries, although uncommon, continue to occur and that the best treatment results are achieved in specialized hepatobiliary units.

Biliary complications after liver transplant: the Victorian experience.

BACKGROUND: Biliary complications remain a continuing problem in liver transplantation. The goals of this study were to document the frequency of biliary complications following orthotopic liver transplantation in the Victorian programme, and to examine associations with suspected risk factors with reference to biliary stenosis. METHODS: Data were collected from 129 consecutive transplants in 123 patients (106 adults, 17 children) at the Austin Hospital, Melbourne during the period 1988-94. The 2 year actuarial survival was 88%. Biliary reconstruction was by end-to-end anastomosis in 89 patients and Roux-en-Y in 40. Complications were suspected on clinical, biochemical or microbiological evidence. Biliary stenoses were considered to be radiological evidence of duct narrowing. RESULTS: Biliary complications occurred in 19% and biliary stenosis in 8.5%. Of the stenoses, 1/35 occurred in the first 20 month period, 9/47 in the second and 1/47 in the third. There was a significant difference between the middle period and other periods (P<0.05, Chi-square test). This change may be related to incomplete flushing of bile from the donor liver. Recurrence of the original disease was suspected for one stenosis. The length of the donor bile duct from hilum to anastomosis, cold ischaemia time and total hepatic artery flow at transplant did not relate to stenosis. Cholangitis was not diagnosed in patients without strictures. Strictures were managed by dilatation (5/11) and by operative repair (6). CONCLUSIONS: Stenoses were not related to the length of the donor bile duct, cold ischaemia time or total hepatic artery flow. Meticulous adherence to the protocol for flushing out bile at the donor operation was associated with a significant reduction in frequency of biliary stenoses.

Choledocholithiasis in anomalous biliary system.

Although congenital biliary abnormalities are common, preduodenal portal vein is very rare, not to mention preduodenal common bile duct (CBD) which has not been described before in the literature. A case with both anomalies complicated by biliary tract stones is reported. A brief review of embryonic development is also presented to explain the unusual biliary anatomy of this patient.

Role of ERCP in asymptomatic orthotopic liver transplant patients with abnormal liver enzymes.

OBJECTIVE: The safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) in the evaluation and management of biliary tract complications after orthotopic liver transplantation (OLT) have been previously demonstrated. However, the role of ERCP in evaluating asymptomatic OLT patients with abnormal liver enzymes with a previously normal biliary tree remains poorly defined. We sought to assess the utility of ERCP in this subset of patients. METHODS: A retrospective analysis of-asymptomatic OLT patients with abnormal liver enzymes evaluated by ERCP was undertaken. In addition to ERCP, all these patients had a diagnostic abdominal Doppler ultrasound, and a percutaneous liver biopsy. All patients had choledochocholedochostomy at the time of transplant and normal T-tube cholangiograms 3 months postoperatively. A radiologist, blinded to clinical findings, interpreted the ultrasound as normal, biliary dilation, or vascular abnormalities. The same radiologist interpreted ERCP findings. A pathologist, blinded to clinical findings, graded liver biopsies as normal, diagnostic, or abnormal but nondiagnostic. RESULTS: Twenty-two patients underwent 23 ERCPs. Twenty-two of the 23 ERCPs were normal (96%), and one abnormal ERCP finding did not explain the liver enzyme abnormality. Liver biopsy was diagnostic in 13 of 22 (57%) and in each case the ERCP was normal. The remaining 10 liver biopsies were abnormal but nondiagnostic. Ultrasound was abnormal in five of 22 cases, but in the three cases suggesting biliary dilation, the ERCP was interpreted as normal. CONCLUSION: Routine use of ERCP in evaluation of asymptomatic OLT patients with liver function test abnormalities and normal cholangiograms at 3 months was not diagnostically useful. In this subset of patients, liver biopsy was usually abnormal and frequently diagnostic and should be the initial invasive diagnostic procedure.

Surgery or endoscopy for palliation of biliary obstruction due to metastatic pancreatic cancer.

BACKGROUND AND AIMS: Both endoscopic and surgical drainage procedures are effective palliative methods for malignant biliary obstruction. Surgical drainage is still preferred in developing countries due to the high cost of procuring metal biliary stents. The aim of this study was to evaluate the quality of life and the cost of care in patients with metastatic pancreatic cancer after endoscopic biliary drainage and surgical drainage. PATIENTS AND METHODS: This is a prospective, randomized controlled trial conducted in a tertiary referral center in Brazil. Patients with biliary obstruction due to metastatic pancreatic cancer and liver metastasis, but without gastric outlet obstruction, were included in the study. Endoscopic biliary drainage with the insertion of a metal stent into the bile duct was compared with the surgical drainage procedure (choledochojejunostomy and gastrojejunostomy). Quality of life was assessed before, and 30 days, 60 days, and 120 days after the drainage procedure. The cost of drainage procedure, cost during the first 30 days and the total cost from drainage procedure to death were calculated. RESULTS: Of the 273 patients with pancreatic malignancy seen at our hospital between July 2001 and October 2004, 35 patients were eligible for the study, and 30 agreed to participate in the study. Both surgical and endoscopic drainage procedures were successful, without any mortality in the first 30 days. The cost of biliary drainage procedure (US dollars 2,832 +/- 519 vs 3,821 +/- 1,181, p= 0.031), the cost of care during the first 30 days after drainage (US dollars 3,122 +/- 877 vs 6,591 +/- 711, p= 0.001), and the overall total cost of care that included initial care and subsequent interventions and hospitalizations until death (US dollars 4,271+/- 2,411 vs 8,321 +/- 1,821, p= 0.0013) were lower in the endoscopy group compared with the surgical group. In addition, the quality of life scores were better in the endoscopy group at 30 days (p= 0.042) and 60 days (p= 0.05). There was no difference between the two groups in complication rate, readmissions for complications, and duration of survival. CONCLUSIONS: Endoscopic biliary drainage is cheaper and provides better quality of life in patients with biliary obstruction and metastatic pancreatic cancer.

Collagen content in rat liver after experimentally induced cholestasis followed by choledochojejunostomy and X-irradiation.

The right part of the median lobe of the liver of female Wistar rats was irradiated, 12.5 or 25 Gy, at a field size of 15 x 20 mm. The central part of the irradiated liver lobe was fixed and used for the estimation of the collagen protein ratio by means of the Sirius Red-Fast Green extraction method, immediately, 8, 16 or 32 weeks after irradiation. No significant increase in collagen content could be demonstrated in this time range, both after irradiation at 12.5 Gy and at 25 Gy. Partial hepatectomy according to Higgins led to rapid regrowth of the remaining liver lobes. The right lobe grew out rapidly to replace the median lobe. Two days after partial hepatectomy the right lobe was irradiated at the same field size. Measurement of the collagen protein ratio in this experiment did not show a significant increase 8, 16 or 32 weeks after irradiation. However, the 25 Gy group did not survive long enough to obtain data at 16 or 32 weeks. The animals in this latter experiment suffered from ascites before dying. Experimentally induced cholestasis was obtained by ligation and partial resection of the common bile duct. After two weeks of cholestasis the bile flow was restored by Roux-en-Y choledochojejunostomy. The effect of irradiation 2 days after repair surgery was studied. Without irradiation the collagen protein ratio is increased. Irradiation of the right part of the median lobe led to a relatively enhanced collagen content in this lobe. Our results indicate that radiation itself does not lead to a significantly enhanced degree of fibrosis in the liver. However when an increase in collagen content was induced by cholestasis, the partial "dilution" of enhanced fibrosis as a result of proliferation of liver parenchyma cells following repair surgery was inhibited by irradiation.

Surgical complications and long-term outcome of different biliary reconstructions in liver transplantation for primary sclerosing cholangitis-choledochoduodenostomy versus choledochojejunostomy.

Choledochojejunostomy (CJS) is commonly used for biliary reconstruction in liver transplantation for primary sclerosing cholangitis (PSC). We alternatively performed choledochoduodenostomy (CDS) and side-to-side choledochodocholedochstomy in a large cohort of patients. Fifty-one patients with PSC, transplanted between 1988 and 2000, were analyzed retrospectively. Biliary reconstruction was CDS in 25 (49%), CJS in 20 (39%) and CC in 6 transplantations (12%). Biliary leaks occurred in the early follow-up (< or =41 days) only in CDS patients (20%). However, in the late follow-up (>4 months), stricturing of anastomosis was found once in CDS (4%) and CJS (5%). Later (>9 months), intrahepatic bile duct strictures were diagnosed in four CDS (16%), one CJS (5%) and one CC (17%) patient(s). In 48% of CDS (12/25), 60% of CJS (12/20) and 17% of CC (1/6) at least one incidence of cholangitis was observed. Overall, biliary complication rates were significantly higher in CDS (40%) than CJS (10%) and CC (17%); of those none in CC and 12% in CDS were anastomosis-related. Graft/patient survival showed no significant differences among groups. Based on our results we consider CJS the standard method for biliary reconstruction in PSC; however, in selected cases where CJS is difficult to accomplish because of previous surgery or for retransplantation, CDS may present an alternative technique.

The predictive value of transabdominal ultrasonography in the diagnosis of biliary tract complications after orthotopic liver transplantation.

BACKGROUND: In transplant recipients with choledococholedocostomy (CDCD), endoscopic retrograde cholangiopancreatography (ERCP) remains the gold standard for the diagnosis of biliary leak or strictures. Transabdominal ultrasonography (TAUS) has been used to screen patients with suspected biliary tract complications, prior to ERCP, although the clinical effectiveness remains unclear. AIMS: To assess the predictive value of TAUS in the diagnosis of biliary tract complications after liver transplantation. METHODS: 144 consecutive ERCP and corresponding ultrasonogram reports performed over a 67 month period in 79 patients after liver transplantation were analysed retrospectively. RESULTS: 77 ERCP patients had both a TAUS and a successful ERCP. Biliary tract abnormalities were found at TAUS in 49 (64%) of the 77 patients. TAUS had an overall sensitivity of 77%, and specificity of 67%, with positive and negative predictive values of 26% and 95% respectively, when adjusted for the prevalence rate of biliary complications after liver transplantation of 12.8% in our population. The use of bile duct calibre as sole criterion for an abnormal scan improved the specificity (76%) and with a corresponding reduction in sensitivity (66%). The risk of false negative TAUS was similar in both the early and late post-transplant periods. CONCLUSIONS: A normal TAUS after liver transplantation with CDCD makes the presence of biliary complications unlikely.

Percutaneous transjejunal approaches to the biliary system.

The authors report 10 cases in which various retrograde manipulations in the biliary tract were performed via percutaneous access from the jejunum in patients who had previously undergone Roux-Y biliary surgery. The first cases involved attempted retrograde cholangiography through the jejunal limb in children who had undergone Roux-Y portoenterostomies, followed by cases of percutaneous placement of U tubes and an attempt at percutaneous creation of an hepaticojejunostomy. When a limb from the Roux-Y has been brought to the skin and marked with clips, jejunal puncture is easily performed, is well tolerated by patients, and may be repeated frequently. It also appears that after Roux-Y choledochojejunostomy, the Roux-Y limb is fixed and may be punctured with relative safety. Since access from below is more favorable for intrabiliary manipulations, the transjejunal approach expands the armamentarium of the interventional radiologist in the combined radiologic and surgical management of complex biliary disease.

Biliary obstruction: findings at MR cholangiography and cross-sectional MR imaging.

Twenty-two patients with malignant biliary obstruction and 21 patients with suspected obstruction of biliary-enteric anastomoses were evaluated over a 12-month period with magnetic resonance (MR) cholangiography and cross-sectional MR imaging. In patients with malignant obstruction, MR cholangiography helped accurately determine the status of the biliary ductal system by identifying the exact location and extent of the obstruction and the severity of duct dilatation. In so doing, MR cholangiography helped determine whether percutaneous transhepatic cholangiography with antegrade stent placement or retrograde cholangiography with stent placement constituted the more suitable treatment. Cross-sectional MR imaging was necessary to identify the organ of tumor origin, define the tumor margins, and determine the stage of disease. This information helped evaluate the appropriateness of curative surgical therapy versus palliative drainage procedures. In patients with biliary-enteric anastomoses, MR cholangiography clearly depicted the site of the anastomosis and demonstrated the status of the intrahepatic ducts, thereby helping determine which patients would benefit from undergoing antegrade duct cannulation with a drainage procedure or perhaps balloon dilation. In some of these patients, MR cholangiography was sufficient to help plan therapeutic intervention. MR cholangiography also demonstrates the presence and size of biliary stones and associated findings such as intraductal tumor growth. In addition, MR cholangiography may obviate retrograde cholangiography, which can be technically difficult to perform.

Biliary complications after liver transplantation in children.

To evaluate the role of interventional radiologic procedures in the diagnosis and treatment of biliary complications in children after liver transplantation, the authors reviewed the cases of 58 pediatric patients who underwent transplantation over a 4-year period. In 21 patients suspected of having biliary complications, 31 diagnostic percutaneous transhepatic cholangiographic studies, 19 transhepatic biliary drainages, eight pressure-flow studies, five percutaneous drainages of abdominal fluid collections, 11 balloon dilations, and one basketing procedure were performed. Biliary complications were seen in 38% of allografts, with obstruction being more common than leakage. Complications were most frequent in patients with cholecystojejunostomy reconstructions. Only two children had biliary complications that were thought to be related to arterial compromise. No significant intervention was required in 17% of complications. Percutaneous techniques were associated with a low frequency of significant complications (6%). The authors conclude that interventional radiologic techniques can be used effectively in the evaluation and management of biliary complications in pediatric hepatic transplant recipients.

Endoscopy as an adjuvant to biliary radiologic intervention.

Twenty-two patients underwent 24 percutaneous biliary procedures guided with choledochoscopy, an adjunctive percutaneous biliary technique. All but four procedures were performed through established percutaneous tracts; the others, through tracts less than 4 weeks old. The procedures were done for the following reasons: removal of calculi (n = 15), electrohydraulic lithotripsy (n = 1), biliary duct biopsies (n = 8), cauterization of a bleeding tract (n = 1), and evaluation of biliary-enteric anastomoses (n = 11). The only complication was one case of severe nausea after choledochoscopy. This patient required overnight hospitalization and medical treatment. All procedures were technically successful, except one case in which the tract was undersized. All patients received intravenously administered antibiotics before and after the procedure. It is concluded that choledochoscopy is a safe, atraumatic, and well-tolerated method of evaluating and treating biliary disease and that it markedly reduces radiation exposure. It can be performed rapidly with minimal sedation on an in- or outpatient basis.

Biliary intervention by means of percutaneous puncture of the antecolic jejunal loop.

PURPOSE: To evaluate the safety and efficacy of biliary intervention performed by means of percutaneous transjejunal access. MATERIALS AND METHODS: In 28 patients with conventional antecolic Roux-en-Y choledochojejunostomy or hepaticojejunostomy loops, 41 attempts were made at direct percutaneous entry into the jejunal loop. Indications for previous surgery included sclerosing cholangitis, orthotopic liver transplantation, cholangiocarcinoma, bypass of benign iatrogenic strictures, and bypass of choledochal cyst. Roux-en-Y loops were directly accessed with single-wall, 19-gauge needles after localization by review of previous cholangiograms or computed tomographic (CT) scans and localization of surgical clips with fluoroscopy. RESULTS: The transjejunal approach was successful in 36 of 41 attempts. In 30 cases, transhepatic puncture was entirely avoided. There were four minor complications and one major complication of biliary sepsis. No procedure-related deaths occurred. CONCLUSION: This transjejunal approach is an effective and safe route for a variety of percutaneous biliary procedures in patients with biliary-enteric anastomoses.

Percutaneous transjejunal biliary intervention: 10-year experience with access via Roux-en-Y loops.

PURPOSE: To assess the safety and efficacy of percutaneous retrograde transjejunal cholangiography and biliary intervention for benign and malignant disease. MATERIALS AND METHODS: The clinical and radiographic records of 43 patients (31 with benign and 12 with malignant disease) who had undergone percutaneous retrograde transjejunal biliary intervention over a 10-year period at a single institution were reviewed. One hundred eighty-one procedures were performed via a fixed Roux-en-Y loop and 15 via an unfixed loop. RESULTS: Percutaneous retrograde transjejunal cholangiography was attempted on 196 occasions (143 for benign and 53 for malignant disease). Primary successful access was obtained in 181 (92.3%). Adjunctive percutaneous transhepatic cholangiography improved successful access in an additional seven procedures, to 188 (95.9%). Interventions included stricture dilation, stone extraction, stent insertion, and brachytherapy. The mean number of biliary interventions and the mean interval between them were 3.1 interventions and 5.9 months in the benign group and 3.6 interventions and 3.8 months in the malignant group. The complication rate was 4.1%, with no deaths or episodes of biliary sepsis. CONCLUSION: Percutaneous transjejunal biliary access allows repeated interventions over many years with a low morbidity. Routine superficial fixation of Roux-en-Y loops is recommended for all biliary-enteric anastomoses to allow use of this safe and effective approach for any subsequent biliary intervention.
