Choledochal cyst.

A 16-year-old girl with recurrent pain in the right upper quadrant and abnormal results of liver function tests was found to have a large choledochal cyst filled with stones. Computerized tomography and endoscopic retrograde cholangiopancreatography showed the large cyst with innumerable primary cyst stones and an anomalous pancreaticobiliary duct junction.

Mirizzi's syndrome.

Mirizzi's syndrome is a partial obstruction of the biliary tree caused by a stone impacted in the cystic duct, with or without development of a cholecysto-biliary fistula. We report our experience with five cases and review current methods of diagnosis and management. Preoperative diagnosis greatly facilitates management. Diagnosis may require a combination of ultrasonography, computed tomography, and cholangiography (percutaneous or endoscopic retrograde). At surgery, dissection in the triangle of Calot should be minimized to avoid injury to the common bile duct. Often, a partial cholecystectomy is the only safe option. Defects in the common bile duct can be repaired by a variety of methods. The morbidity and mortality associated with this rare syndrome can be relatively high. A number of patients may have late biliary strictures.

Palliative procedures for pancreatic cancer: when and which one?

Pancreatic cancer usually requires palliative rather than curative therapy. Palliative procedures should have low morbidity and mortality, provide a good quality of life, and necessitate minimal hospitalization. The surgeon, endoscopist, and radiologist all play a role in delivering effective palliation to properly selected patients.

Biliary tract complications of side-to-side without T tube versus end-to-end with or without T tube choledochocholedochostomy in liver transplant recipients.

BACKGROUND: Biliary anastomotic complications remain a major cause of morbidity in liver transplant recipients, ranging between 10% and 50% in large clinical series. An end-to-end choledochocholedochostomy with or without T tube (CDCD EE with T tube and CDCD EE w/o T tube) and a Roux-en Y choledochojejunostomy have been standard methods for biliary drainage. METHODS: The objectives of this retrospective study were to: (1) evaluate the incidence of biliary tract complications using a new method of side-to-side choledochocholedochostomy without T tube (CDCD SS w/o T tube) and (2) compare the results of CDCD SS w/o T tube with those of CDCD EE with T tube and CDCD EE w/o T tube. From September 1991 through June 1996, 279 orthotopic liver transplants were performed in 268 patients and followed through December 1996 (minimum of 6 months' follow-up). A total of 227 CDCD anastomoses in 220 patients were studied (7 retransplants > 30 days): CDCD EE with T tube (n=124), CDCD EE w/o T tube (n=44), and CDCD SS w/o T tube (n=59). RESULTS: Sixty-nine biliary complications were observed in 220 patients (30%). Anastomotic and/or T-tube leaks were seen in 43 patients (19%), and anastomotic strictures were found in 26 patients (12%). Forty patients (18%) required percutaneous or endoscopic stent placement (6%) or surgical interventions (12%). CDCD EE with T tube had the highest incidence of biliary leak requiring rehospitalization but the lowest anastomotic stricture and intervention rate and the lowest 6-month mortality rate. CONCLUSIONS: CDCD EE with T tube was superior to CDCD EE or CDCD SS w/o T tube despite the increased number of rehospitalizations. CDCD SS w/o T tube did not offer significant advantages over conventional biliary anastomotic techniques.

Laparoscopic choledochoduodenostomy: review of a 4-year experience with an uncommon problem.

A laparoscopic choledochoduodenostomy (LCDD) may be performed when the common bile duct (CBD) is obstructed by primary or secondary stones or strictures. A biliary bypass procedure has two goals in view. The short-term goal is complete removal of stones and bypass of obstruction and stricture to restore biliary drainage. The long-term goal is preventing a recurrence of the problem. There is debate over the superiority of any one procedure to achieve both goals. Therefore, it may help the practicing clinician to be aware of the success (or failure), on a case-by-case basis, of these procedures. This awareness may help in the choice of technique. To date, since 1991, we have performed 16 LCDDs; however, in this report, we describe our results with LCDD over the last 4 years to emphasize the usefulness of this procedure. We find that it is a safe and effective procedure for treating patients with benign bile duct obstruction, even for those whose condition may be described as complicated or difficult. Evidence is slowly accumulating that LCDD is also successful in promoting long-term biliary drainage. We reviewed our LCDDs done over the past 4 years, documenting our preoperative, intraoperative, and postoperative experience. A successful LCDD was performed on all six patients. None of the patients had postoperative leaks. There was only one death, which was due to the patient's comorbidities and not the procedure itself. The hepatobiliary enzyme levels returned to normal in all of the surviving patients. The average postoperative length of stay was 6 days. With proper selection and adequate laparoscopic experience, LCDD can be performed in a safe and effective way.

Laparoscopic Roux-en-Y choledochojejunostomy for benign biliary disease.

Roux-en-Y choledochojejunostomy (RYCJ) is frequently used for biliary bypass surgery. However, reports on laparoscopic RYCJ are scarce. Between February 1997 and February 2002, laparoscopic RYCJ was performed in 6 patients with a recurrent common bile duct (CBD) stone or a benign biliary stricture. The first procedure involved the laparoscopic preparation of the CBD. The Roux limb prepared with an endo-GIA was brought up near the proximal CBD. An end-to-side choledochojejunostomy was then performed using an intracorporeal suture. Jejunojejunostomy was performed using an endo-GIA. The mean operating time was 358.3 minutes. A postoperative complication occurred in 1 patient who had an episode of melena, which resolved spontaneously. All patients were free of symptoms during the follow-up period (27.5 months). Laparoscopic RYCJ may be a useful option, especially in the treatment of benign biliary disease.

Imaging after a whipple operation: improving visibility of the afferent jejunal loop in spiral computed tomography using biliary contrast medium.

OBJECTIVE: Spiral computed tomography (CT) examination of patients after a Whipple operation often raises questions concerning the afferent loop. This study evaluates the efficiency of biliary contrast medium (BCM) in visualizing opacification of this loop. METHODS: After undergoing a Whipple operation, 31 patients received 100 mL BCM before postoperative spiral CT (Somatom Plus 4; Siemens, Erlangen, Germany: 5- or 10-mm slices, feed of 7 or 12 mm/s; Volume Zoom; Siemens: 2.5 mm collimation, total feed of 15 mm/s). Semiquantitative evaluation included opacification of the jejunal loop and visibility of jejunostomies. Complications and tumor recurrences were recorded. RESULTS: In all patients, BCM was successfully administered without complications. Afferent loop opacification was seen in 95% of examinations with BCM versus 5% of examinations with oral contrast medium. Evaluation of jejunostomies was unequivocally facilitated by BCM. Three previously undetermined changes were identified as tumor recurrence, and recurrence was ruled out after examination with BCM in 7 cases. CONCLUSIONS: After a Whipple operation, opacification of the afferent loop can be regularly achieved by intravenous administration of BCM, which eases distinction of normal postoperative changes from local tumor recurrence. Administration of BCM is recommended as a standard diagnostic procedure in these patients.

Hepatobiliary scintigraphy in liver transplant patients: the "blind end sign" and its differentiation from bile leak.

PURPOSE: Hepatobiliary scintigraphy is commonly performed on liver transplant patients to exclude biliary complications such as obstruction or leak. Biliary reconstruction in these patients is performed using either a direct duct-to-duct anastomosis (choledochocholedochostomy) or a biliary-enteric anastomosis (Roux-en-Y hepaticojejunostomy). The authors have observed a finding in scans performed on the latter group of patients that often simulates a bile leak. They postulate this finding to represent retention of activity in the blind end of the Roux limb (the "blind end sign"). The purpose of this study was to determine characteristics of this blind end activity, which may help differentiate it from true bile leaks. METHODS: Two nuclear medicine physicians reviewed 36 Tc-99m mebrofenin hepatobiliary scans (31 patients). Biliary reconstruction was performed in 25 patients with a Roux-en-Y hepaticojejunostomy, and in 6 patients with a choledochocholedochostomy. Each scan was evaluated regarding whether there was focal, persistent retention of activity in the anastomotic region, and, if so, various features of the activity were noted. Activity was concluded to represent a true bile leak based on subsequent surgical confirmation, and if there was no such confirmation, the activity was concluded to represent blind end retention in patients with Roux-en-Y hepaticojejunostomies. RESULTS: There were 8 total examples of blind end activity and 3 examples of bile leak activity. Useful discriminators between the 2 types of activity included the following: fluctuation in size and/or intensity with time (8 of 8 blind end cases vs. 0 of 3 bile leak cases); size comparable with bowel (8 of 8 vs. 1 of 3); tubular (4 of 8 vs. 0 of 3), round (4 of 8 vs. 1 of 3), or irregular (0 of 8 vs. 2 of 3) shape; and movement into bowel (3 of 8 vs. 0 of 3). Delayed imaging was performed in 3 cases at 1.5 hours, but was only conclusive in 1 case in which diffuse extravasation was seen consistent with bile leak. CONCLUSION: Retention of activity in the blind end of the Roux limb in patients with Roux-en-Y hepaticojejunostomies may simulate bile leak, but certain typical features, as well as delayed imaging, may aid in distinguishing the two.

Percutaneous cholecystocholedochostomy for cholecystitis and cystic duct obstruction in gallbladder carcinoma.

Percutaneous cholecystocholedochostomy was performed in a patient with acute cholecystitis caused by cystic duct obstruction by gallbladder carcinoma, but removal of the percutaneous cholecystostomy catheter was unsuccessful because of continuing discharge. After creation of a cholecystocholedochostomy through the cholecystostomy tract with use of a transjugular liver access set and a 21-gauge needle, self-expandable metallic stents were placed in the narrowed common bile duct and the newly created tract between the gallbladder and the common hepatic duct. The external cholecystostomy catheter was successfully removed after the procedure. Jaundice occurred 70 days later as a result of tumor invasion above the segment with the stent, and an additional stent was placed. The patient died of diffuse metastasis 143 days after creation of the cholecystocholedochostomy without recurrence of cholecystitis.

Long-term prognosis after treatment of patients with choledocholithiasis.

OBJECTIVE: This study was conducted to examine the long-term prognosis of after treatment of patients with choledocholithiasis, including the recurrence of lithiasis, and to thereby determine the best treatment modality for choledocholithiasis based on its pathological entity. SUMMARY BACKGROUND DATA: Choledocholithiasis can be caused by either primary bile duct stones that originate in the bile duct or by secondary bile duct stones that have fallen out of the gallbladder. The recurrence rates vary depending on the type of choledocholithiasis. METHODS: Two-hundred thirteen outpatients who were treated for choledocholithiasis from 1982 to 1996 were selected as subjects and monitored for a period ranging from 5 to 19 years (mean, 9.6 years). The 213 patients were divided into 3 groups: 87 patients who had undergone choledocholithotomy and T-tube drainage (including the use of the laparoscopic method), 44 patients who had undergone choledochoduodenostomy, and 82 patients whose stones were removed by endoscopic sphincterotomy (EST). Recurrence of lithiasis was examined for each type of treatment modality. RESULTS: Choledochoduodenostomy was performed in 44 cases for the purpose of preventing any recurrence. The recurrent rate was analyzed in 169 cases. Choledocholithiasis recurred in 17 of the 169 cases (10.1%). The remaining 152 patients that showed no recurrence of lithiasis were examined and compared. The diameter of the common bile duct measured during the initial treatment was more dilated in patients with recurrent lithiasis (16.6 +/- 5.9 mm) than in patients without any recurrence (9.8 +/- 4.9 mm; P < 0.05). Peripapillary diverticula were observed in 10 of the 17 patients with recurrent lithiasis (58.8%), and in 34 of the 152 nonrecurrent patients (22.3%), showing that diverticula were more common in recurrent cases (P < 0.05). Furthermore, while primary bile duct stones were found in 11 of the 17 cases with recurrent lithiasis (64.7%), primary stones were found in only 37 of the 152 nonrecurrent patients (24.3%), showing primary bile duct stones were also more common in recurrent patients (P < 0.05). The recurrent patients were examined by surgical procedure. Nine patients with choledocholithotomy and T-tube drainage had a recurrence (10.3%), and 8 patients in the EST group had a recurrence (9.8%). The recurrence rates for these procedures were higher than for cases with choledochoduodenostomy (recurrence rate: 0%, P < 0.05). In particular, lithiasis recurred in 5 of the 12 patients with T-tube drainage for primary bile duct stones (41.7%). CONCLUSION: Although choledocholithotomy and T-tube drainage, including open and laparoscopic surgery, is presently a common procedure for choledocholithiasis, this procedure will not necessarily prevent a recurrence of the disease. For older patients with primary bile duct stones, choledochoduodenostomy or EST is recommended.

Biliary reconstruction in right lobe living-donor liver transplantation: Comparison of different techniques in 321 recipients.

OBJECTIVE: To assess the incidence of biliary complications after right lobe living-donor liver transplantation (LDLT) in patients undergoing duct-to-duct choledochocholedochostomy or Roux-en-Y choledochojejunostomy reconstruction. SUMMARY BACKGROUND DATA: Biliary tract complications remain one of the most serious morbidities following liver transplantation. No large series has yet been carried out to compare the 2 techniques in LDLT. This study undertook a retrospective assessment of the relation between the method of biliary reconstruction used and the complications reported. METHODS: Between February 1998 and June 2004, 321 patients received right lobe LDLT. Biliary reconstruction was achieved with Roux-en-Y choledochojejunostomy in 121 patients, duct-to-duct choledochocholedochostomy in 192 patients, and combined Roux-en-Y and duct-to-duct choledochocholedochostomy in 8 patients. The number of graft bile duct and anastomosis, mode of anastomosis, use of stent tube, and management of biliary complications were analyzed. RESULTS: The overall incidence of biliary complications was 24.0%. Univariate analysis revealed that hepatic artery complications, cytomegalovirus infections, and blood type incompatibility were significant risk factors for biliary complications. The respective incidence of biliary leakage and stricture were 12.4% and 8.3% for Roux-en-Y, and 4.7% and 26.6% for duct-to-duct reconstruction. Duct-to-duct choledochocholedochostomy showed a significantly lower incidence of leakage and a higher incidence of stricture; however, 74.5% of the stricture was managed with endoscopic treatment. CONCLUSIONS: The authors found an increase in the biliary stricture rate in the duct-to-duct choledochocholedochostomy group. Because of greater physiologic bilioenteric continuity, less incidence of leakage, and easy endoscopic access, duct-to-duct reconstruction represents a feasible technique in right lobe LDLT.

Roux-en-Y Choledochojejunostomy is the method of choice for biliary reconstruction in liver transplantation for primary sclerosing cholangitis.

BACKGROUND: Opinion is divided regarding the optimal method of biliary reconstruction after liver transplantation for primary sclerosing cholangitis (PSC). METHODS: We investigated biliary complications and graft and patient survival in all patients who underwent liver transplantation for PSC in the United Kingdom between 1994 and 2003. RESULTS: Anastomotic leak rates were similar, but a significantly higher stricture rate was observed in patients who had a duct-to-duct reconstruction compared with those who underwent a Roux-en-Y anastomosis. Graft and patient survival were also markedly worse in patients with a duct-to-duct anastomosis. CONCLUSIONS: Roux-en-Y choledochojejunostomy is the method of choice for biliary reconstruction in liver transplantation for PSC.

The Hutson loop and prosthesis: clinical uses in hepato-biliary intervention.

A number of method of making a Roux-en-Y hepaticojejunostomy have been advocated to help the radiologist gain access to the biliary system. We have found markers and rings unsatisfactory and therefore designed and tested our own prosthesis. Reliable rapid access is easily achieved using this device with a much reduced radiation dose to both patient and radiologist. The prosthesis has been used for the past 3 years, and the last 23 patients are reviewed. Seven patients have required repeated interventions via the loop and we present the findings and our results.

Percutaneous extraction of retained common bile-duct stones via the T-tube track.

A total of 86 procedures were performed in 58 patients referred in the postoperative period, for percutaneous stone extraction through the T-tube track. In 43 patients, the stone or stones were extrahepatic, intrahepatic in nine, and both intrahepatic and extrahepatic in six patients. Of the 58 patients with residual bile-duct stone(s), 48 (83%) were treated successfully by percutaneous removal, seven (12%) had an endoscopic sphincterotomy following unsuccessful T-tube track extraction, one (2%) had a re-operation and two (3%) remain with residual stones. No major complications occurred in this series. In contrast to endoscopic sphincterotomy, percutaneous T-tube extraction of retained bile-duct stones is associated with no mortality and low morbidity and is advocated as the procedure of choice in the presence of a T-tube.

Common duct exploration or endoscopic sphincterotomy for choledocholithiasis?

The relative indications for operative common duct exploration (CDE) and endoscopic sphincterotomy (ES) in treating common duct stones are often unclear. This prospective study compared CDE and ES in treating choledocholithiasis after excluding patients with acute cholecystitis, idiopathic pancreatitis, sphincter of Oddi dysfunction and malignant disease. One hundred and two patients had 105 CDE and a further 50 patients had 57 ES. Of the patients having CDE, 76 also had cholecystectomy for gall-bladder (GB) disease while 26 had prior cholecystectomy. With ES, in 16 the GB was present and not removed while 34 patients had had prior cholecystectomy. Hospitalization was significantly less following ES. There was one peri-operative death after CDE and none after ES. There were two late biliary-related deaths, 3 and 27 months after ES, in patients who developed acute cholecystitis. In post-cholecystectomy patients having ES, complications were fewer and less severe after ES (15%) than CDE (41%). In patients with an intact GB, peri-operative complications occurred in 30% after cholecystectomy and CDE. Following ES alone, complications occurred in 33% with the majority of these complications arising from the diseased GB. It is concluded that the optimal treatment for post-cholecystectomy patients with bile-duct stones is ES. In elderly patients with an intact GB, the bile-duct stones can be treated by ES; whether subsequent cholecystectomy is necessary should be assessed on the likelihood of future GB complications.
