Comparative evaluation of scintigraphy and upper gastrointestinal tract endoscopy for detection of duodenogastric reflux.

Duodenogastric reflux, the reflux of duodenal bile into stomach, when suspected clinically requires an objective evaluation for proper management. In this study hepatobiliary scintigraphy in 91 patients of different clinical conditions was evaluated for presence of duodenogastric reflux. Upper gastrointestinal endoscopy was also performed in 44 of these patients. On scintigraphy duodenogastric reflux was present in 26 (29%) of 91 patients. Upper gastrointestinal endoscopy revealed presence of refluxed bile in the stomach in 12 (27%) of 44 patients. In the same groups of patients scintigraphy detected reflux in 18 (41%) of 44 patients. This shows that hepatobiliary scintigraphy is superior to upper gastrointestinal endoscopy in detection of duodenogastric reflux and also has the advantage of being non-invasive and physiological.

Hepatic artery pseudoaneurysm after liver transplantation. A result of transhepatic biliary drainage for primary sclerosing cholangitis.

Hepatic artery pseudoaneurysm (HAP) is a rare but often life-threatening complication of liver transplantation. Treatment is usually ligation, revascularization, or retransplantation. We report a patient suffering from primary sclerosing cholangitis who required transhepatic percutaneous biliary drainage. Following orthotopic liver transplantion (OLT), he developed HAP, which was successfully embolized angiographically. We discuss the association between transhepatic biliary drainage and the development of HAP after OLT, and the possibilities for angiographic intervention in these cases.

Infection rates with and without T-tube splintage of common bile duct anastomosis in liver transplantation.

Stenting the bile duct over a T-tube after orthotopic liver transplantation (OLT) is the preferred method of biliary reconstruction. However, because of complications associated with the use of the T-tube, we evaluated the effect of various biliary anastomoses following 100 consecutive OLT (83 records were available for long-term evaluation) and assessed the clinical outcome of abandoning routine T-tube splintage. Of 16 OLT recipients with T-tube splintage (one died immediately following OLT and was excluded from the study), 6 patients (40%) developed six episodes of septicaemia secondary to biliary and/or intra-abdominal sepsis. Four of these six patients had a biliary leak (27%). Of 57 patients with duct-to-duct anastomosis without T-tube splintage, 7 patients developed biliary leak (12.3%) and only 1 developed septicaemia (1.7%) secondary to biliary and intra-abdominal sepsis (P = 0.0002). Of 11 patients with either a gallbladder conduit or Roux loop, only 1 patient had a biliary leak (9%) and there were no septicaemic episodes. In conclusion, direct duct-to-duct anastomosis resulted in significantly less morbidity due to infection without T-tube splintage than the use of a T-tube following OLT, but there were no significant differences in leakage and stricture rates.

Biliary reconstruction with or without an internal biliary stent in orthotopic liver transplantation: a prospective randomised trial.

Choledochocholedochostomy (CCD) with a 7 fr/8 fr Cotton Leung internal biliary stent removed at endoscopic retrograde cholangiography (ERC) 3 months following orthotopic liver transplantation (OLT) was the technique used on our unit for biliary reconstruction. From June 1995 to July 1996, we randomised 37 OLT patients with CCDs to receive either an internal stent (group I, nd = 18) or no stent (group II, n = 19). Patients in group I had an ERC at 3 months for stent removal whereas patients in group II had an ERC if indicated. The mean follow up was 19 (13-26) months. Biliary complications occurred in 9 out of 18 patients in group 1 compared to 1 out of 19 patients in group II (P = 0.007). In group I, ERC was required for complications in 8 patients and early surgery in 2, compared to 1 ERC for abnormal liver function tests in group II. Five of the early complications in group I were stent related. Late biliary stenosis occurred in 1 patient at 9 months. There was one stent-related death. The use of stents contributes to biliary complications and CCD without stenting is safe after OLT.

Clinical value of MRC in the follow-up of liver transplant patients with a choledochojejunostomy.

BACKGROUND: We investigated the clinical value of magnetic resonance cholangiography (MRC) in liver transplant patients receiving choledochojejunostomy (CDJ). METHODS: Twenty-five MRCs were performed in 23 initially asymptomatic patients 19 months (mean) after liver transplantation with biliary reconstruction via CDJ. The images were evaluated by consensus (two investigators) for bile duct strictures and dilatations. As a standard of reference, clinical follow-up (including laboratory analysis) was used in 20 cases and direct cholangiography or surgery in three cases. RESULTS: Fourteen pathologic findings were observed in 11 patients (anastomotic strictures in four, left or right bile duct strictures in three, and peripheral segmental dilatations with or without strictures in seven). Patients with pathologic MRC findings had significantly higher levels of alkaline phosphatase (p < 0.05) and more frequently had histories of cholangitis than did patients with normal MRC. Four of six patients with stenoses of the central bile ducts subsequently developed biliary complications requiring treatment (three confirmed by direct cholangiography). In patients with unremarkable bile ducts or only peripherally located changes on MRC, no bile duct complications or relevant changes in the cholestasis parameters occurred during follow-up (mean = 30 months). CONCLUSION: MRC can noninvasively detect pathologic biliary tract changes in liver transplant patients in the asymptomatic stage and provide information for planning invasive therapeutic procedures.

Dilatation of biliary strictures through the afferent limb of a Roux-en-Y choledochojejunostomy in patients with sclerosing cholangitis.

Repeated dilatation of biliary strictures in patients with sclerosing cholangitis through a subcutaneously placed afferent limb of a choledochojejunostomy is technically feasible and safe. This study is a prospective 15-year evaluation of 36 patients treated by repeat dilatation through this jejunal limb. There was one operative death and one major complication of dilatation. The 5-year survival of all patients was 74%. If patients with cirrhosis or unproven cholangiocarcinoma at the time of operation are not included, the 5-year survival is 86%. The 15-year survival of all patients was 30%; it was 64% if those with cirrhosis and unproven cholangiocarcinoma at the time of operation are not included. Six patients are presently alive with an average survival of 159 months. The study suggests that a combination of repeated dilatations combined with transplantation is the approach of choice in selected patients.

Choledochocholedochostomy conversion to hepaticojejunostomy due to biliary obstruction in liver transplantation.

Choledochocholedochostomy with tutor (CC-T) or without (CC) is the technique of choice for biliary reconstruction in orthotopic liver transplantation (OLT), however, its rate of complications is high and does not decrease significantly over the years. Biliary obstruction is the most frequent complication and surgical treatment frequently involves conversion to hepaticojejunostomy (H-J). Out of 412 patients (448 OLTs) analyzed retrospectively, 74 (18%) presented biliary complications and 25 (6%) required conversion to H-J because of biliary obstruction, generally due to anastomotic stenosis (17 patients, 68%). Sixteen out of the 25 presented after the first 3 months, and in two patients, stenosis was secondary to arterial thrombosis. Anastomotic stenosis was more frequent in the CC group than in the CC-T group (9.9% versus 2.6%, p < 0.05). Sixteen patients (64%) underwent percutaneous dilatations, but the response was only transitory. There were no postoperative deaths. At the follow-up, three (12%) of the 17 surviving patients presented episodes of cholangitis which required percutaneous dilatations (1), revision of the H-J (1), or conversion to hepaticojejunoduodenostomy (1). Mean survival of patients with H-J was 70.9%, and the actuarial survival rate was 68% at 5 years. This does not differ from the actuarial survival in our series of transplanted patients (65%). CC or CC-T (in selected cases) is an adequate biliary reconstruction for OLT, in spite of the fact that a small number of patients will require conversion to H-J. H-J is an excellent technique of rescue in cases of biliary obstruction that are not possible to resolve by percutaneous dilatations.

Complications following repair of extrahepatic bile duct injuries after blunt abdominal trauma.

Extrahepatic bile duct traumatic injuries are extremely rare and their treatment is difficult and with several controversies. The aim of this study was to offer some more clinical information on their surgical repair and outcome. We present seven patients with extrahepatic biliary tract lesions after blunt abdominal trauma, (isolated gallbladder lesions were excluded) four males and three females from 23 to 51 years of age (mean age 35.1 years). All patients had suffered high-energy blunt abdominal trauma and presented associated injuries, mostly liver trauma and lung contusions. Six gallbladder lesions and six common bile duct injures were identified; a right hepatic duct laceration and a left hepatic duct transection were also present. Injuries were treated either with primary repair or with duct-jejunal anastomoses with Roux-en-Y reconstruction. Principal complications were postoperative anastomotic leakage (1 case) and recurrent cholangitis (3 cases) with or without stricture. Not-diagnosed injuries caused substantial morbidity. We prefer and recommend the use of primary repair in partial ruptures with no significant tissue loss and biliary-enteric anastomoses in large injuries and complete transections because they offer the best long-term drainage with less risk of stricture formation than end-to-end anastomoses. We defend the use of long duration (6 to 9 months) transanastomotic stents.

Prospective randomized study of T-tube versus biliary stent for common bile duct decompression after open choledocotomy.

The T-tube has been the alternative of choice for decompression following common bile duct (CBD) exploration. The development of laparoscopic surgery has suggested using a biliary stent as an alternative to the T-tube following choledochotomy. The purpose of this prospective randomized study was to compare clinical results obtained from patients who underwent open CBD exploration using a biliary stent versus those from patients with a T-tube for decompression. Between September 2000 and June 2002 a total of 81 patients were randomly assigned to a biliary stent or a T-tube as the decompression method following choledochotomy. An open CBD exploration was performed when CBD stones were suspected, in both elective and emergency settings. The length of the postoperative hospital stay was 6.8 +/- 4.7 days for patients with the T-tube and of 5.2 +/- 3.3 days for, patients with the biliary stent (p = 0.19). Postoperative complications were observed in 13 patients (30%) with the T-tube and in 4 patients (11%) with the biliary stent (p = 0.03). One patient with a biliary stent was reoperated because of an intraabdominal abscess, and another patient was reoperated because of biliary peritonitis following T-tube removal. Three patients (7%) with a biliary stent and one patient (3%) with a T-tube were rehospitalized. There were no deaths. The T-tube and biliary stent were removed 27.1 +/- 10.8 days and 34.9 +/- 12.9 days after surgery, respectively (p = 0.24). The biliary stent is a safe alternative to the T-tube as a biliary decompression method following an open CBD exploration.

Primary closure of the common duct over endonasobiliary drainage tubes.

The T-tube remains the standard method of intraductal drainage after open choledochotomy for choledocholithiasis. We studied the use of an endonasobiliary drainage (ENBD) tube as an alternative to the T-tube for postoperative intraductal drainage. A series of 20 patients with documented choledocholithiasis in whom endoscopic methods of stone retrieval failed to clear the common bile duct (CBD) were selected for the study. All patients had ENBD tubes placed preoperatively at endoscopic retrograde cholangiopancreaticography and then were subjected to open choledocholithotomy with primary closure of the choledochotomy over the ENBD. The age of the patients in the study group ranged from 18 to 75 years. Three patients (15%) had acute cholangitis at the time of surgery. Stones were confirmed at surgery in 85% of the patients, and the size of the CBD was found to range from 1.0 to 2.3 cm. All 20 patients underwent closure of the common duct over an ENBD tube without any difficulty. None of the patients experienced biliary complications such as bile leaks, biliary peritonitis, biliary fistula, pancreatitis, or cholangitis. No patient had any residual stone as documented by postoperative cholangiograms. Abdominal drains remained in place for 2 to 4 days, and the ENBD tubes were removed between days 6 and 8. The length of the postoperative hospital stay varied from 7 to 15 days, with 65% of the patients going home before postoperative day 8.

Choledocholithiasis: percutaneous treatment.

The percutaneous approach to retained biliary duct stones is most reasonable in the presence of a T-tube because of the low morbidity and mortality as well as its low cost. We report our experience with 373 patients, emphasizing the technique and the solutions to some frequent problems.

Choledochoduodenostomy for common bile duct stones.

Among the techniques for dealing with common bile stones, choledochoduodenostomy (CDS) represents a useful alternative. This operation is indicated mainly in patients with recurrent stones, giant stones, or concomitant common bile stricture and duct stones. At the present time most of the patients undergoing CDS have been already undergone endoscopic retrograde cholangiography or ultrasonography to study the common bile duct and the cause of symptoms. The common bile duct diameter is of paramount importance when determining the feasibility of performing a CDS, the critical size being 1.2 cm. The most common operation is a side-to-side anastomosis employing absorbable sutures. Stomal patency is the most important factor for preventing classic complications such as cholangitis and sump syndrome. These complications are rare, being observed in only 5% of the patients. Long-term results of the operation show that it is a safe procedure that should be considered a good option in selected patients with choledocholithiasis.

Management of benign biliary strictures.

Benign biliary strictures are most commonly a consequence of injury at laparoscopic cholecystectomy or fibrosis after biliary-enteric anastomosis. These strictures are notoriously difficult to treat and traditionally are managed by resection and fashioning of a choledocho- or hepato-jejunostomy. Promising results are being achieved with newer minimally invasive techniques using endoscopic or percutaneous dilatation and/or stenting and these are likely to play an increasing role in the management. Even low-grade biliary obstruction carries the risks of stone formation, ascending cholangitis and hepatic cirrhosis and it is important to identify and treat this group of patients. There is currently no consensus on which patient should have what type of procedure, and the full range of techniques may not be available in all hospitals. Careful assessment of the risks and likely benefits have to be made on an individual basis. This article reviews the current literature and discusses the options available. The techniques of endoscopic and percutaneous dilatation and stenting are described with evaluation of the likely success and complication rates and compared to the gold standard of biliary-enteric anastomosis.

Novel use of a T-tube access to perform an internal/external biliary drainage.

We report a case of post-surgical temporary functional stenosis of the sphincter of Oddi and biliary leak in a patient with a previous Billroth II reconstruction who had undergone cholecystectomy, surgical choledochotomy and sphincterotomy for biliary calculi. The patient was treated by creation of an internal/external biliary drainage using the T-tube access with an unreported technique.

Portal flow into the liver through veins at the site of biliary-enteric anastomosis.

The aim of this study was to establish the role played by jejunal veins in hepatopetal flow after biliary-enteric anastomosis and to evaluate the helical CT features of hepatopetal flow through the anastomosis. We retrospectively analyzed helical CT images of the liver in 31 patients with biliary-enteric anastomosis who underwent hepatic angiography with (n=13) or without (n=18) CT arterial portography within 2 weeks of the CT examination during the last 4 years. Arterial portography showed hepatopetal flow through small vessels located (communicating veins) between the elevated jejunal veins and the intrahepatic portal branches in two (9%) of 22 patients with a normal portal system. Helical CT showed focal parenchymal enhancement around the anastomosis in these two patients. All nine patients with extrahepatic portal vein occlusion (100%) had hepatopetal flow through the anastomosis, and four of the nine had decreased portal flow. CT revealed small communicating veins in two of these four patients. In five patients with normal portal perfusion despite extrahepatic portal vein occlusion, CT detected dilated communicating veins and elevated jejunal veins. The presence of communicating veins and/or focal parenchymal enhancement around the anastomosis indicates hepatopetal flow through the elevated jejunal veins.

Bacteria ascend to liver from the bilioenteric conduit after choledochojejunostomy in the cholestatic rat.

The high incidence of postoperative cholangitis in children with clinical restoration of bile flow after Roux-Y choledochojejunostomy (RYCJ) assumed the concept of a direct ascending cholangitis caused by pathogens in the intestine, into the intrahepatic bile duct via the porta hepatis. It is also well known that jaundiced animals (patients) are more susceptible to infections of the bile ducts following the procedure of bilioenteric anastomosis. An animal experiment was conducted to compare quantitative bacterial cultures of the choledochojejunostomy area and the liver 24 hours after Escherichia coli (ATCC 25922) or sterile normal saline was injected into the bilioenteric conduit (BEC), following RYCJ in rats with or without the proceeding bile duct ligation. A significant increase of E. coli of the same strain (ATCC 25922), that we injected into the BEC, was proved with pulse-field gel electrophoresis (PFGE) and shown in the liver of the jaundiced rats receiving E. coli (ATCC 25922), compared to that in the nonjaundiced rats with normal saline treatment. It is concluded that bacteria often ascend early to the liver from the BEC following RYCJ. This ascending cholangitis model might be produced for further studies.

Rapid enlargement of a choledochal cyst: antenatal diagnosis and delayed primary excision.

A case of choledochal cyst (CC) antenatally diagnosed at 29 weeks' gestation is reported. Rapid enlargement of the cyst soon after delivery resulted in complete gastric outlet obstruction (GOO). The lesion was treated by external drainage as a temporary maneuver, with delayed cyst excision and hepaticoduodenostomy at the hepatic hilum performed at 81 days of age. Surgical treatment of CC in early infancy has been reported to be safe and effective. However, delayed primary excision would be an alternative procedure, especially in rare cases showing rapid enlargement resulting in GOO, since this choice has the potential advantage of allowing weight gain and improved nutritional status without risking interim complications due to the drainage procedure.
