Endoscopic management of biliary fistulas complicating liver transplantation and other hepatobiliary operations.

OBJECTIVE: This study was undertaken to prospectively evaluate the efficacy and safety of endoscopic management of biliary fistulas complicating liver transplantation and other hepatobiliary operations. SUMMARY BACKGROUND DATA: Surgical therapy has been the traditional approach to large or unresolving biliary fistulas complicating liver transplantation. Although endoscopic management is rapidly becoming an acceptable alternative to surgery for the treatment of biliary fistulas complicating non-liver transplant hepatobiliary operations, it has received limited attention in the liver transplant setting. METHODS: During a 15-month period, 146 adults underwent liver transplantation with biliary reconstruction by end-to-end choledochocholedochostomy over a T-tube. Inadvertent T-tube migration or intentional T-tube removal resulted in bile peritonitis in 18 patients. The patients were treated with a nasobiliary tube (n = 13), internal stent plus endoscopic sphincterotomy (n = 3), or internal stent alone (n = 2). Thirteen patients had a biliary fistula after other hepatobiliary operations and underwent endoscopic therapy during a similar period. All 13 had an endoscopic sphincterotomy with removal of obstructing stones when present (n = 6). Twelve patients also had stents placed. All patients were prospectively followed after hospital discharge and assessed for recurrent symptoms suggestive of biliary tract disease and procedure-related complications. RESULTS: Endoscopic retrograde cholangiopancreatography (ERCP) identified a biliary fistula at the T-tube insertion site into the bile duct in all 18 liver transplant patients. Seventeen patients had resolution of their symptoms within 12 hours of therapy. The fistula sealed in 94.4%. In the other hepatobiliary operation group, ERCP demonstrated contrast extravasation from the biliary tree in 12 of 13. The biliary fistula closure rate was 92.3%. The endoscopic complication rate for the two groups was 3.2%. During a mean follow-up of 9 months, recurrent biliary tract complications occurred in 11.1% of the liver transplant group and 0% in the other hepatobiliary operation group (p > 0.05). The 30-day mortality rate was 0%. CONCLUSIONS: The results of this study support the application of endoscopic management of biliary fistulas complicating orthotopic liver transplantation and other hepatobiliary operations. This approach was relatively safe and obviated the need for surgical intervention.

Technique and results of biliary reconstruction using side-to-side choledochocholedochostomy in 300 orthotopic liver transplants.

OBJECTIVE: The authors evaluated the complication rate and outcome of side-to-side common bile duct anastomosis after human orthotopic liver transplantation. SUMMARY BACKGROUND DATA: Early and late biliary tract complications after orthotopic liver transplantation remain a serious problem, leading to increased morbidity and mortality. Commonly performed techniques are the end-to-end choledochocholedochostomy and the choledochojejunostomy. Both techniques are known to coincide with a high incidence of leakage and stenosis of the bile duct anastomosis. The side-to-side bile duct anastomosis has been shown experimentally to be superior to the end-to-end anastomosis. The authors present the results of 316 human liver transplants, in which a side-to-side choledochocholedochostomy was performed. METHODS: Biliary tract complications of 370 transplants in 340 patients were evaluated. Three hundred patients received primary liver transplants with side-to-side anastomosis of donor and recipient common bile duct. Thirty-two patients with biliary tract pathology received a bilioenteric anastomosis, and in eight patients, side-to-side anastomosis was not performed for various reasons. Clinical and laboratory investigations were carried out at prospectively fixed time points. X-ray cholangiography was performed routinely in all patients on postoperative days (PODs) 5 and 42. In patients with suspected papillary stenosis, endoscopic retrograde cholangioscopy and papillotomy were performed. RESULTS: One biliary leakage (0.3%) was observed within the early postoperative period (PODs 0 through 30) after liver transplantation. No stenosis of the common bile duct anastomosis was observed during this time. Late biliary stenosis occurred in two patients (0.6%). T tube-related complications were observed in 4 of 300 primary transplants (1.3%). Complications unrelated to the surgical technique, including papillary stenosis (5.7%) and ischemic-type biliary lesion (3.0%), which must be considered more serious in nature than complications of the anastomosis or T tube-related complications, were observed. Papillary stenosis led to frequent endoscopic interventions and retransplantations in 1.3%. CONCLUSIONS: Side-to-side common bile duct anastomosis represents a safe technique of bile duct reconstruction and leads to a low technical complication rate after human orthotopic liver transplantation. Ischemic-type biliary lesion evoked by preservation injury, arterial ischemia, cholestasis, and cholangitis may represent a new entity of biliary complication, which markedly increases the morbidity after human liver transplantation. Therefore, this complication should be the subject of further research.

The long-term outcome of hepaticojejunostomy in the treatment of benign bile duct strictures.

OBJECTIVE: The authors review the treatment and outcome of patients with benign bile duct strictures who underwent biliary enteric repair. SUMMARY BACKGROUND DATA: The authors conducted a retrospective review of all clinical records of patients referred for treatment of benign bile duct strictures caused by surgery, trauma, or common bile duct lithiasis or choledochal cyst. The authors performed univariate and multivariate analyses of clinical and pathologic factors in relation to patient outcome and survivals. METHODS: Eighty-four patients with documented benign bile duct strictures underwent hepaticojejunostomy, choledochojejunostomy, and intrahepatic cholangiojejunostomy during a 15-year period (January 1975 to December 1989). Morbidity, mortality, and patient survival rates were measured. RESULTS: Early and late outcomes correlated neither with demographic and clinical features at presentation nor with etiologic or pathologic characteristics of the stricture. Best results correlated with high biliary enteric anastomoses and degree of common bile duct dilatation independently of bile duct stricture location. CONCLUSIONS: High biliary enteric anastomosis provides a safe, durable, and highly effective solution to the problem of benign strictures of the bile duct. Transanastomotic tube stenting is unnecessary. Endoscopic and percutaneous transhepatic dilatation seems more appropriate for the treatment of patients in poor condition and those with anastomotic strictures.

Randomized trial of choledochocholedochostomy with or without a T tube in orthotopic liver transplantation.

OBJECTIVE: To compare the incidence of biliary complications after liver transplantation in patients undergoing choledochocholedochostomy reconstruction with or without T tube in a multicenter, prospective, randomized trial. SUMMARY BACKGROUND DATA: Several reports have suggested that biliary anastomosis without a T tube is a safe method of biliary reconstruction that could avoid complications related to the use of T tubes. No large prospective randomized trial has so far been published to compare the two techniques. METHODS: One hundred eighty recipients of orthotopic liver transplantation were randomly assigned to choledochocholedochostomy with (n = 90) or without (n = 90) a T tube in six French liver transplantation centers. All types of biliary complications were taken into account. RESULTS: The overall biliary complication rate was increased in the T-tube group, even though these complications did not lead to an increase in surgical or radiologic therapeutic procedures. The major significant complication was cholangitis in the T-tube group; this did not occur in the other group. The incidence of biliary fistula was 10% in the T-tube group and 2.2% in the group without a T tube. Other biliary complications were similar. The complication rate of cholangiography performed with the T tube was greater than with other types of biliary exploration. The graft and patient survival rates were similar in the two groups. CONCLUSION: This study is the first large prospective, randomized trial of biliary complications with or without a T tube. The authors found an increase in the biliary complication rate in the T-tube group, which was linked to minor complications. The T tube did not provide a safer access to the biliary tree compared with the others types of biliary explorations. The authors recommend the performance of choledochocholedochostomy without a T tube in liver transplantation.

Late development of bile duct cancer in patients who had biliary-enteric drainage for benign disease: a follow-up study of more than 1,000 patients.

OBJECTIVE: To evaluate the correlation between biliary-enteric surgical drainage and the late development of cholangiocarcinoma of the biliary tract. SUMMARY BACKGROUND DATA: In patients with biliary-enteric drainage, reflux of intestinal contents into the bile duct may occur and cause cholangitis, which is regarded as the most serious complication of these procedures. Lithiasis of the biliary tract and a previous biliary-enteric anastomosis have both been suggested to favor the late onset of cholangiocarcinoma. METHODS: Consecutive patients (n = 1,003) undergoing three different procedures of biliary-enteric anastomosis (transduodenal sphincteroplasty, choledochoduodenostomy, and hepaticojejunostomy) between 1967 and 1997 were included in this study. The postoperative clinical course and long-term outcome were evaluated by a retrospective review of the hospital records and follow-up. Mean follow-up was 129.6 months. RESULTS: Fifty-five (5.5%) cases of primary bile duct cancer were found among the 1,003 patients at intervals of 132 to 218 months from biliary-enteric anastomosis. The incidence of cholangiocarcinoma in the three groups was 5.8% in transduodenal sphincteroplasty patients, 7.6% in choledochoduodenostomy patients, and 1.9% in hepaticojejunostomy patients. The incidence of malignancy related to the different underlying diagnosis was 5.9%, 7.2%, and 1.9% in patients with choledocholithiasis, sphincter of Oddi stenosis, and postoperative benign stricture, respectively. Although only one patient who developed cholangiocarcinoma had previous concurrent lithiasis of the biliary tract, 40 patients had experienced mostly severe, recurrent cholangitis. No case of malignancy occurred in patients scored as having no cholangitis in the early and long-term postoperative outcome. Univariate and multivariate analyses have shown the presence of cholangitis as the only factor affecting the incidence of cholangiocarcinoma. CONCLUSIONS: Chronic inflammatory changes consequent to biliary-enteric drainage should be closely monitored for the late development of biliary tract malignancies.

Choledochal cysts in the adult.

Although choledochal cyst is generally considered a disorder of childhood, in approximately 20% of patients a cyst is first recognized in adult life. We reviewed nine adults who underwent operation for choledochal cyst from 1974-1985 at Yale New Haven Hospital. Presenting symptoms included: crampy right upper quadrant pain, jaundice, pruritus, cholangitis, pancreatitis, hepatomegaly, and elevated liver function tests. Seven patients had undergone previous biliary surgery. The eight patients with type I cysts underwent complete excision of the cysts with Roux-Y choledochojejunostomy. One patient with a type IVa cyst underwent Roux-Y cystjejunostomy. All patients had complete resolution of biliary symptoms. There were no deaths, serious complications, or development of biliary malignancy in the 6 months to 13 years of follow-up. Optimum treatment of choledochal cyst is complete excision with reconstruction by Roux-Y choledochojejunostomy.

Primary choledochoduodenostomy for benign obstructive biliary tract disease.

Repeated surgical interventions on the biliary ductal system increase morbidity and mortality, particularly in the geriatric patient. In an attempt to prevent these complications, side-to-side choledochoduodenostomy was performed as the primary operative procedure in 54 patients, age 72 +/- 13 years. This was the patients' first surgical intervention for benign obstructive lesions of the biliary tract system. Indications for choledochoduodenostomy were: multiple or irremovable common or hepatic duct stones, doubtfulness of complete clearing of the duct, primary common bile duct stones or mud and sludge, a grossly dilated biliary duct system, and ampullary stenosis. We encountered no operative or hospital mortality among this group of 54 patients. The mean postoperative hospital stay for this aged and relatively sick group of patients was 12.3 +/- 6.2 days. Twenty-three minor postoperative complications occurred in 18 patients, none of them requiring reoperation. The patients were followed for 2-16 years. Thirteen patients (24%) were lost to follow-up. Of the 41 patients available for follow-up, 14 died, none from biliary tract associated causes--mostly from cerebrocardiovascular disease. Twenty-seven patients still alive were found to be free of biliary tract associated abdominal complaints or recurrent cholangitis for a mean period of 7.8 +/- 3.7 years. The data indicate a zero reoperation rate during long-term follow-up, zero mortality rate, and low morbidity in a group of elderly, mostly poor risk patients. This leads us to conclude that a side-to-side choledochoduodenostomy is both the best therapy as well as prophylaxis against common duct stones. This, even in this era of endoscopic papillotomy and biliary lithotripsy.

Periampullary gangliocytic paraganglioma.

A33-year-old man presented with features of obstructive jaundice. Enterohepatic retrograde cholangiopancreatography examination revealed a periampullary growth. After pancreatoduodenectomy, histologic examination of the growth revealed three elements: a spindle cell element, large ganglion cells, and smaller paraganglioma-like cells arranged in small nests and groups. A diagnosis of gangliocytic paraganglioma was given. Gangliocytic paraganglioma is a rare benign duodenal tumor, with uncertain histogenesis. It is possible to identify the three components that are essential for its diagnosis on routine hematoxylin and eosin sections without the use of immunohistochemical markers. Because this lesion may present clinically as a periampullary carcinoma, it is important to recognize and diagnose this rare, but benign, entity.

Risk factors for recurrent cholangitis after initial hepatolithiasis treatment.

GOALS: To elucidate the risk factors that can affect the rate of cholangitis after hepatolithiasis treatment. BACKGROUND: Hepatolithiasis is prevalent in East Asia and causes long-term complications. Recurrent cholangitis is one of its most serious complications and can lead to biliary stricture, liver cirrhosis, and even cholangiocarcinoma. However, little is known about the risk factors associated with cholangitis. STUDY: The clinical records of 193 patients with hepatolithiasis who had been newly diagnosed and treated were reviewed. The mean follow-up was 56 months (1-242 months). RESULTS: Cumulative cholangitis rates were 25.0% at 3 years and 37.0% at 5 years. By multivariate analysis, cholangitis was associated with hepatic resection (Hazard ratio [HR] = 0.28; 95% confidence interval [CI]: 0.12-0.65), residual stones (HR = 1.77; 95% CI: 1.05-2.98), and recurrent stones (HR = 4.02; 95% CI: 1.31-12.36), but not Sphincter of Oddi disruption. Though biliary stricture did not in general affect the cholangitis rate, a stricture located in the common hepatic or common bile duct was associated with a higher rate of cholangitis than a stricture in the intrahepatic duct alone. CONCLUSIONS: Cholangitis occurs frequently in hepatolithiasis patients with a common hepatic or common bile duct stricture, residual stones, recurrent stones, and in those that are treated by nonhepatic resection.

Choledocholithiasis in infants: diagnostic and therapeutic problems.

During the 3-year period, January 1986 through December 1988, 7 of 24 infants evaluated for cholestatic liver disease were found to have choledocholithiasis with or without associated gallbladder disease. Five were born prematurely with associated predisposing factors, especially systemic infection and total parenteral nutrition. The clinical course varied from spontaneous recovery in two patients to ongoing liver disease requiring surgical or endoscopic intervention in five infants. Asymptomatic patients with normal liver function and persistently dilated extrahepatic biliary trees posed the most difficult therapeutic problems. Endoscopic retrograde cholangiography appeared to be an effective and rewarding therapeutic approach.

Hepatobiliary scintigraphy for the diagnosis of bile leaks produced after T-tube removal in orthotopic liver transplantation.

Choledochocholedochostomy (CC) over a T-tube is a well-recognized technique for biliary reconstruction in orthotopic liver transplantation (OLT). Bile leaks after T-tube removal are common, having a significant morbidity. The aim of this study was to evaluate the utility of hepatobiliary scintigraphy (HBS) for diagnosing bile leaks in liver transplant patients who develop abdominal pain after T-tube removal. Twenty consecutive patients (14 males, 6 females; mean age 44 years) were studied. The interval between T-tube removal and HBS ranged from 8 to 120 h. Hepatobiliary scintigraphy was carried out after the intravenous injection of 185 MBq 99Tc(m)-mebrofenin. A final diagnosis of bile leak was based on surgical, endoscopic retrograde cholangiopancreatography (ERCP) and ultrasound data, and clinical outcome. There were 13 patients with and 7 without bile leaks. On the scintigraphic images, bile leaks were defined as activity outside the biliary tract which moved along the right paracolic gutter, or the progressive accumulation of activity related to fluid collections as seen on ultrasound. Nine of 12 patients needed surgical repair; the other 3 were treated with endoscopic sphincterotomy. One patient with a negative HBS developed an abdominal abscess after aspirative puncture of a biloma. In the seven patients without bile leaks, all scintigrams showed normal biliary transit of activity. A diagnosis of no bile leaks was based on clinical follow-up in five patients and by ERCP in two patients. Based on these results, we conclude that HBS is an effective method for the diagnosis of bile leaks after T-tube removal in liver transplant patients.
