1/65. Are expandable metallic stents better than conventional methods for treating difficult intrahepatic biliary strictures with recurrent hepatolithiasis?BACKGROUND: Conventional methods for treating patients with recurrent hepatolithiasis associated with complicated intrahepatic biliary strictures include balloon dilatation of the intrahepatic biliary strictures, lithotripsy, and the clearance of difficult stones as completely as possible, with the placement of an external-internal stent for at least 6 months. After these modalities are used, symptomatic refractory strictures remain. Recently we used internal Gianturco-Rosch metallic Z stents to treat patients who had refractory strictures. OBJECTIVE: To compare therapeutic results and complications of an internal expandable metallic Z stent with those of repeated external-internal stent placement. STUDY DESIGN: Case-control study. SETTING: A referral center. patients: From January 1992 to December 1996, 18 patients with recurrent hepatolithiasis and complicated intrahepatic biliary strictures underwent percutaneous dilatation of stricture and transhepatic percutaneous cholangioscopic lithotomy for recurrent stones. After their stones were completely cleared, their biliary strictures failed to dilate satisfactorily. The patients were randomly enrolled into 2 groups: group A (7 patients), who received an expandable metallic Z stent, and group B (11 patients), who had repeated placement of external-internal stents. INTERVENTIONS: Percutaneous stricture dilatation, electrohydraulic lithotripsy, balloon dilatation, percutaneous transhepatic cholangioscopic lithotomy, and biliary stenting by a Silastic external-internal catheter or a modified Gianturco-Rosch expandable metallic Z stent (for an internal stent). MAIN OUTCOME MEASURES: The number of procedures, days in hospital, procedure-related complications, incidents of stone recurrence and recurrence of cholangitis, readmissions to the hospital, treatment sessions required, and mortality rate. patients' limitations in ordinary activities were also compared. RESULTS: The follow-up period ranged from 28 to 60 (40.7 /-12.7 [mean /- SD]) months in group A and from 28 to 49 (36.0 /-7.2) months in group B. Fewer group A patients (3 [43%]) than group B patients (8 [73%]) tended to have recurrent cholangitis and to require readmission to the hospital, but this was not statistically significant (P = .33). When their cumulative probability of a first episode of cholangitis during follow-up was compared, however, it was significantly lower in patients treated with a metallic stent (P = .04). Compared with group B patients, group A patients had less frequent recurrence of stones (0% vs 64%; P = .01), fewer procedures for the clearance of biliary stones or sludge (1.7 /-2.2 vs 6.4 /-4.3; P = .03), and shorter hospital stays (8.0 /-11.5 days vs 17.0 /-12.0 days; P = .07). No patients in group A experienced limitation in ordinary activities, whereas 7 patients in group B did (P<.02). CONCLUSIONS: Compared with the repeated placement of external-internal stents, the use of a metallic internal stent effectively decreases stone recurrence, simplifies further procedures, and is more convenient. Its use is suggested as an alternative choice in the treatment of recurrent hepatolithiasis with refractory intrahepatic biliary strictures.- - - - - - - - - - ranking = 1keywords = cholangitis (Clic here for more details about this article) |
2/65. Hepaticojejunostomy after excision of choledochal cyst in two children with previous biliary surgery.Hepaticojejunostomy Roux-en-Y after excision of choledochal cyst is the treatment of choice for children with choledochal cyst, to prevent the risk of postoperative cholangitis, stone formation and malignancy. The author reports two children with previous biliary surgery for choledochal cyst, one with cystojejunostomy without cholecystectomy and the other with cholecystectomy alone. Two children were admitted to the Pediatric Surgical Unit, Ratchaburi Hospital, with the complaint of chronic abdominal pain. After investigation the two children had cyst excision and hepaticojejunostomy Roux-en-Y. After six and one year follow-up the patients remain asymptomatic. The aim of this report was to show the complication of two previous biliary surgeries for choledochal cyst and support total cyst excision combined with hepaticojejunostomy Roux-en-Y being the treatment of choice for choledochal cyst.- - - - - - - - - - ranking = 0.33333333333333keywords = cholangitis (Clic here for more details about this article) |
3/65. Right hepatic lobectomy for bile duct injury associated with major vascular occlusion after laparoscopic cholecystectomy.A 57-year-old woman underwent laparoscopic cholecystectomy (LC) for cholelithiasis. Continuous bile leak was observed beginning on the first postoperative day. Postoperative endoscopic retrograde cholangiography revealed bile leak through the common hepatic duct, and severe stenosis of the hepatic confluence. A total of three percutaneous transhepatic biliary drainage (PTBD) catheters were inserted to treat obstructive jaundice and cholangitis. The patient was referred to our hospital for surgery 118 days after LC. cholangiography through the PTBD catheters demonstrated a hilar biliary obstruction. Celiac arteriography revealed obstruction of the right hepatic artery, and transarterial portography showed occlusion of the right anterior portal branch. On the basis of the cholangiographic and angiographic findings, we performed a right hepatic lobectomy with hepaticojejunostomy to resolve the bile duct obstruction and address the problem of major vascular occlusion. The patient's postoperative recovery was uneventful and she remains well 25 months after hepatectomy. We discuss a treatment strategy for bile duct injury suspected after LC, involving early investigation of the biliary tree and prompt intervention.- - - - - - - - - - ranking = 0.33333333333333keywords = cholangitis (Clic here for more details about this article) |
4/65. Doppler sonography in hepatolithiasis: a case report.In the treatment of hepatolithiasis, it is important to not only remove all stones and eliminate bile stasis in the biliary tract, but also to remove atrophic hepatic tissue, as such tissue may cause recurrent cholangitis as well as latent cholangiocarcinoma. A 75-year-old woman was diagnosed as having hepatolithiasis with stenosis at the branching of the bile ducts in segment II and segment III by sonography, computed tomography, endoscopic retrograde cholangiography, and magnetic resonance cholangiography. Portograms did not reveal portal branches in segment III but did demonstrate the portal branches in segment II. During the operation, Doppler sonography was done. Doppler sonography did not reveal the portal blood flow in segment III, but did demonstrate a "to-and-fro" pattern in the portal branches in segment II, indicating atrophic hepatic tissue with disrupted portal blood flow. Lateral segmentectomy (resection of segments II and III and lithotomy with choledo-chotomy were done. The patient is in good health 2 years 6 months after the operation. Doppler sonography is useful in the detection of disrupted portal blood flow and the diagnosis of hepatic atrophy. This is clearly advantageous in the decision-making about whether to perform a liver resection with hepatolithiasis.- - - - - - - - - - ranking = 0.33333333333333keywords = cholangitis (Clic here for more details about this article) |
5/65. Primary intrahepatic lithiasis: report of a case treated by laparoscopic bilioenteric anastomosis.Recent advances in videolaparoscopic surgery have made this method the treatment of choice for many biliary diseases. However, it has not been used in certain cases, such as primary intrahepatic lithiasis. The authors report a case of a 62-year-old woman with a history of several episodes of cholangitis. Investigation revealed dilated intra- and extrahepatic bile ducts with intrahepatic stones. The patient underwent laparoscopy, and intraoperative cholangiography disclosed an enlarged common duct with absence of stones and the presence of multiple calculi in the intrahepatic biliary tree. A choledochotomy followed by choledochoscopy was performed, which revealed several intrahepatic pigmented stones that were completely retrieved, followed by a laterolateral choledochoduodenostomy to decompress the biliary tree and to allow the migration of residual or recurrent stones. The patient had an uneventful recovery and was discharged on the fourth postoperative day. After 15 months of follow-up the patient is asymptomatic with normal results of liver function tests. Late postoperative upper digestive endoscopy showed a patent choledochoduodenostomy.- - - - - - - - - - ranking = 0.33333333333333keywords = cholangitis (Clic here for more details about this article) |
6/65. Cholecystogastric fistula presenting with haematemesis: diagnosed by endoscopic retrograde cholangiography.The case is reported of a 72-year-old woman suffering from morbid obesity, who presented with haematemesis while on anti-coagulant therapy. The source of the bleeding proved to be the gastric exit of a cholecystogastric fistula. Subsequent cholangitis was successfully treated by endoscopic retrograde cholangiography (ERC) and endoscopic sphincterotomy (ES) while simultaneously the extent of the fistula was established. cholecystectomy and closure of the fistula was contraindicated because of her morbid obesity. She remained well for 6 months but then presented with a gallstone ileus while another stone was found to be escaping from the gastric fistula. Her morbid obesity resulted in surgical procrastination, which eventually proved fatal. This patient experienced both of the most common types of complication in cholecysto-enteral fistulation, cholangitis and gallstone ileus. Although cholecysto-enteral fistulas (CEF) are probably less common than several decades ago, they are now most likely to be diagnosed during ERC. Gastroenterologists therefore need to be aware of their potential to contribute to the diagnosis and treatment of this surgical condition.- - - - - - - - - - ranking = 0.66666666666667keywords = cholangitis (Clic here for more details about this article) |
7/65. The role of liver transplantation in patients with Caroli's disease.Caroli's disease, characterized by segmental or diffuse dilation of the intrahepatic biliary ducts, is a rare disease which is difficult to treat. The course of the disorder is characterized by recurrent episodes of cholangitis and hospital stays, with a consequent loss of quality-of-life and productive capacity, often ending in death due to uncontrolled infection. Endoscopic drainage of the bile duct, percutaneously or surgically, is palliative, and presents bad results in the follow-up of these patients. Orthotopic liver transplantation appears to be an effective curative option for the treatment of patients with Caroli's disease associated to complications. The authors present the course of two cases of this disease, associated with congenital fibrosis of the liver worsened by repeated episodes of cholangitis, submitted to orthotopic liver transplantation.- - - - - - - - - - ranking = 0.66666666666667keywords = cholangitis (Clic here for more details about this article) |
8/65. Right hepatic segmentectomy for the treatment of intrahepatic biliary stones due to ascaris lumbricoides: report of a case.We report herein the case of a 46-year-old woman investigated for recurrent acute cholangitis. Ultrasound, endoscopic retrograde cholangiopancreatography, and computed tomography scan revealed dilatation and multiple images suggestive of intrahepatic biliary stones in the ducts that drained segments V and VI of the liver. Endoscopic treatment was attempted unsuccessfully, and based on the severity of the last crisis of cholangitis a laparotomy was performed. A right hepatic lobectomy including segments V and VI was carried out without any complications, resulting in complete relief of symptoms. Pathological examination of the liver demonstrated the presence of worm nests in the liver parenchyma with chronic granulomatous lesions.- - - - - - - - - - ranking = 0.66666666666667keywords = cholangitis (Clic here for more details about this article) |
9/65. Cholangiojejunal fistula caused by bile duct stricture after intraoperative injury to the common hepatic artery.A 68-year-old man, admitted for the treatment of recurrent cholangitis after a pancreatoduodenectomy (PD) performed 3 years previously was diagnosed as having multiple hepaticolithiasis. On laparotomy, the hepatic artery was not recognized. The anastomosed common hepatic duct was obstructed, and a fistula had been formed between the right hepatic duct and the Roux limb of the jejunum. lithotripsy was performed from this fistula and it was reanastomosed. Angiography was performed postoperatively and it revealed common hepatic artery injury, most likely to have occurred during the previous PD. The patient's postoperative course was uneventful and he has been asymptomatic for 8 months after the operation, indicating that reanastomosis of the fistula can be an effective method. The stricture of the anastomosis was suspected to be mainly due to cholangial ischemia, because no episode of anastomotic leak or retrograde biliary infection had occurred during the PD perioperative period. There are several reports of late stricture of anastomosis 5 or more years after cholangiojejunostomy. This patient, therefore, requires further long-term follow up.- - - - - - - - - - ranking = 0.33333333333333keywords = cholangitis (Clic here for more details about this article) |
10/65. Recurrent pyogenic cholangitis.A 26-year-old male presented with jaundice and recurrent cholangitis. ultrasonography revealed dilated intra- and extrahepatic biliary tree packed with multiple calculi. Endoscopic retrograde cholangiopancreatography and computerised tomography scan confirmed the findings and a diagnosis of recurrent pyogenic cholangitis was made. cholecystectomy, choledocholithotomy with removal of stones and Roux-en-Y choledochojejunostomy were performed.- - - - - - - - - - ranking = 2keywords = cholangitis (Clic here for more details about this article) |
