(1/130) Double gallbladder originating from left hepatic duct: a case report and review of literature.

BACKGROUND: Double gallbladder is a rare anomaly of the biliary tract. Double gallbladder arising from the left hepatic duct was previously reported only once in the literature. CASE REPORT: A case of symptomatic cholelithiasis in a double gallbladder, diagnosed on preoperative ultrasound, computed tomography (CT) and endoscopic retrograde cholangiopancreatogram (ERCP) is reported. At laparoscopic cholangiography via the accessory gallbladder no accessory cystic duct was visualized. After conversion to open cholecystectomy, the duplicated gallbladder was found to arise directly from the left hepatic duct; it was resected and the duct repaired. CONCLUSIONS: We emphasize that a careful intraoperative cholangiographic evaluation of the accessory gallbladder is mandatory in order to prevent inadvertent injury to bile ducts, since a large variety of ductal abnormality may exist.  (+info)

(2/130) Proximal bile duct cancer: high resectability rate and 5-year survival.

OBJECTIVE: To review and update the authors' experience with resectional surgery for proximal bile duct carcinoma (Klatskin tumor) and assess the role of liver resection over the past 25 years. BACKGROUND: Until recently, resection of proximal bile duct carcinoma was uncommon, with most patients undergoing palliative procedures. The authors adopted a radical surgical approach aimed at definitive cure in 1974. Recent reports suggest that resection improves outcome. METHODS: The records of 40 of 94 patients (23 men, 17 women, age range 34-81 years) diagnosed with proximal bile duct carcinoma who underwent resection between 1968 and 1993 were reviewed. According to the Bismuth classification, there were five type I, four type II, 25 type III, and six type IV lesions; 11 patients underwent tumor resection alone, and 25 patients had combined tumor and liver resection (seven of these also underwent an associated regional vascular resection). In 3 patients, venous allografts were harvested from cadaveric donors and used to reconstruct the portal vein. Four patients underwent liver transplantation; in two, organ cluster-type resections including the liver with porta hepatitis and pancreas were performed. RESULTS: The resectability rate in the more recent period of the study was 49.4%. Most type I, three (of four) type II, T in situ, T1a, T1b, and all stage 0 tumors were resected without hepatectomy. In the other subgroups of tumors, the main surgical procedure was hepatectomy. Thirty-day mortality was 12.5%. After tumor resection alone, survival at 1, 3, and 5 years was 81.8%, 45.5%, and 27.3%, respectively. After tumor resection and hepatectomy without vascular resection, 1-, 3-, and 5-year survival was 66.7%, 16.7%, and 6%, respectively. With vascular resection, survival rates were similar: 64%, 20%, and 4%, respectively. CONCLUSION: The type of surgery required to achieve cure is closely related to tumor location, TNM classification, and staging. Increasing resectability through the use of hepatectomy improves survival and offers a chance of cure in patients with more advanced disease.  (+info)

(3/130) The preoperatively normal bile duct does not dilate after cholecystectomy: results of a five year study.

BACKGROUND: The common hepatic duct (CHD) is commonly believed to dilate after cholecystectomy but previous studies have either not measured CHD diameter preoperatively or the follow up period is short. AIMS: To measure CHD diameter before and after cholecystectomy. METHODS: Patients undergoing (open) cholecystectomy and operative cholangiography had ultrasonographic measurement of CHD diameter before, and three and six months, and one and five years after cholecystectomy. The normal duct diameter was considered to be 5 mm or less, with an observer error of +/-1 mm. RESULTS: Fifty nine patients with normal diameter ducts were studied. The majority (more than 95%) of patients did not have a dilatation of the CHD beyond 6 mm after cholecystectomy. The CHD appeared to increase as well as decrease with an overall trend towards a minor increase at five years. This was not statistically significant if the margin of error of 1 mm was taken into account. CONCLUSION: A preoperatively normal CHD does not dilate after cholecystectomy and may require further investigation in symptomatic patients.  (+info)

(4/130) Posterior hepatic duct injury during laparoscopic cholecystectomy finally necessitating hepatic resection: case report.

A case of bile duct injury during laparoscopic cholecystectomy finally necessitating right hepatic lobectomy is reported to re-emphasize the importance of preoperative and intraoperative assessment of the biliary tree. A 47-year-old Japanese woman underwent laparoscopic cholecystectomy for cholecystolithiasis. On postoperative day 5, fever and right hypochondralgia developed, and CT revealed fluid collection at the right hypochondrium. Percutaneous drainage was performed, and subsequent fistulography revealed a communication of the cystic cavity with the right posterior bile duct, which suggested injury of the aberrant hepatic duct. Conservative therapy, including the adaptation of fibrin glue, was performed, but closure of the fistula and cavity was not obtainable. Finally, a right hepatic lobectomy was performed four months after cholecystectomy. In this case, endoscopic retrograde cholangiopancreatography was unsuccessful preoperatively, and intraoperative cholangiography was not done. This case report re-emphasizes that the preoperative and intraoperative examination of the biliary tree is mandatory to avoid bile duct injury.  (+info)

(5/130) Radiologic findings of Mirizzi syndrome with emphasis on MRI.

We have reported a case of Mirizzi syndrome preoperatively diagnosed using MR cholangiopancreatography. MRCP and T2-weighted image using a single-shot fast spin-echo sequence accurately depicted all components of Mirizzi syndrome, including impacted stone in the neck of the gallbladder compressing the common hepatic duct and wall-thickening of the gallbladder without any evidence of malignancy. The combination of MRCP and T2-weighted image can be counted on to replace conventional modalities of diagnosing Mirizzi syndrome without any loss of diagnostic accuracy.  (+info)

(6/130) Roux-en-Y hepaticojejunostomy: a reappraisal of its indications and results.

A critical evaluation is made of 131 patients submitted to choledocho or hepaticojejunostomy. The main indications for hepaticojejunostomy were iatrogenic strictures of CBD (60 patients), and choledocholithiasis with markedly dilated duct (41 patients). The overall mortality rate was 4% representing principally renal hepatic failure, bile peritonitis and bleeding. The complications following hepaticojejunostomy included only in one case biliary fistula which required reoperation. The long-term results of 80 patients available for a followup study were as follows: 63 patients (78.7%) were symptom-free at 2-13 years followup; 8 patients had brief episodes of cholangitis which responded to antibiotic and corticosteroid treatment; 9 patients required reoperation for stricture of anastomosis. These overall results are a strong argument for hepaticojejunostomy which, compared with choledochoduodenostomy, avoids the hazards of the so-called sump syndrome and of the reflux of enteric contents in the CBD. An increased incidence of peptic ulcer disease in the patients submitted to hepaticojejunostomy was not observed. In very high strictures and in reinterventions anastomosis between left hepatic duct and Roux-en-Y jejunal limb was carried out. The results achieved with this technique, which was performed in 26 patients, were about the same following hepaticojejunostomy.  (+info)

(7/130) Extrahepatic biliary obstruction due to post-laparoscopic cholecystectomy biloma.

BACKGROUND: Jaundice presenting after cholecystectomy may be the initial manifestation of a serious surgical misadventure and requires rigorous diagnostic pursuit and therapeutic intervention. Biloma is a well recognized postcholecystectomy complication that often accompanies biliary ductal injury. CASE REPORT: A 23-year-old female underwent laparoscopic cholecystectomy for symptomatic gallstones and three weeks postoperatively developed painless jaundice. Radiographic and endoscopic studies revealed a subhepatic biloma causing extrinsic compression and obstruction of the common hepatic duct. RESULTS: Percutaneous catheter drainage of the biloma combined with endoscopic sphincterotomy successfully relieved the extrahepatic biliary obstruction and resolved the intrahepatic ductal leak responsible for the biloma. CONCLUSION: Although heretofore undescribed, postcholecystectomy jaundice due to extrahepatic bile duct obstruction caused by biloma may occur and can be successfully treated by means of standard radiologic and endoscopic interventions.  (+info)

(8/130) Biliary anastomosis in living related liver transplantation using the right liver lobe: techniques and complications.

Since the introduction of adult-to-adult living donor liver transplantation using the right lobe of the liver, biliary problems have led the list of complications resulting in postoperative morbidity. We report our experience with the first 30 living donor liver transplantations performed in our institution from August 1998 to January 2000. Patients were 21 men and 9 women, with a mean age 45 +/- 16 years. Mean recipient weight was 65.1 +/- 17.9 kg, mean graft weight was 877 +/- 146 g, and the mean graft-recipient weight ratio was 1.5 +/- 0.6. Patient and graft survival rates were 83.3% and 80%, respectively. Biliary anastomosis was either an end-to-end hepaticocholedochostomy with a T-drain or hepaticojejunostomy. Mean follow-up was 217.4 +/- 149.8 days. The overall complication rate was 26.6% (8 of 30 procedures) and was directly correlated to the type of anastomosis and number of bile ducts. Surgical revision was necessary in all cases. Biliary complications were not the primary cause of graft loss. Adult living donor liver transplantation using the right lobe is a successful procedure, with graft and patient survival similar to those in cadaver full-organ transplantation. Postoperative morbidity, mainly caused by biliary leak, was directly related to the number of ducts and type of anastomosis. With increasing experience, we have better defined our plane of transection on the hilar plate, with the goal of obtaining only 1 biliary duct for the anastomosis. We also improved our parenchymal transection technique, which resulted in a decreased incidence of leak at the cut-surface area.  (+info)
