Intrabiliary Rupture of a Hepatic Hydatid Cyst: A Case Report.

BACKGROUND Hydatid disease is a common parasitic infection in many areas of Asia, South America, and Africa. It can affect any organ, most commonly the liver. The hydatid is often asymptomatic and the diagnosis is made when complications arise. The most common complication of this disease is opening in the bile ducts, which is a life-threatening condition causing serious acute cholangitis. We report a case of acute cholangitis caused by hydatid cyst rupture into the right bile duct. CASE REPORT A 33-year-old woman, with no medical or surgical history, presented to our Emergency Department with abdominal pain, jaundice, and fever for 3 days prior to admission. The patient was hemodynamically stable. In the examination, we noticed right upper-quadrant tenderness with guarding, icterus sclera, and negative Murphy sign. A CT scan showed a liver hydatid cyst of the 4th and 8th of segments, with intrahepatic and extrahepatic biliary duct dilation. The cyst communicated with the right hepatic bile duct via a large fistula. A diagnosis of acute cholangitis was made and she underwent conservative treatment with external drainage of the pericystic cavity through the biliary duct. The postoperative course was uncomplicated and she was discharged 15 days later. CONCLUSIONS The surgical approach to hepatic hydatid must be customized based on the specific characteristics of the cyst and associated complications. Acute hydatid cholangitis is a rare but serious complication of a hydatid cyst, which requires early diagnosis and adequate surgical management.

Biliary Taeniasis: Case Series and Literature Review.

Biliary taeniasis is uncommon in clinical practice. We report two cases in our hospital. The first patient was diagnosed with acute biliary pancreatitis. Endoscopic retrograde cholangiopancreatography (ERCP) showed a white, flat, segmented 1-cm-wide tapeworm drilling into the duodenal papilla that was identified as Taenia saginata. After tapeworm removal, bile duct sweeping, and anthelmintic therapy, the patient recovered uneventfully. The second patient was diagnosed with acute cholangitis and multiple stones in the common bile duct and gallbladder. Emergency ERCP showed no tapeworm in the duodenum. During a subsequent ERCP 6 days later, a flat tapeworm, also T. saginata, was identified drilling into the duodenal papilla. We review five patients cases with acute acalculous cholecystitis or cholangitis caused by T. saginata or Taenia solium, and 1 patient with T. saginata drilling into the T-tube. Taeniasis should be taken into consideration when dealing with biliary and pancreatic disease.

Cholecysto-Hydatid Cyst Fistula: A Rare Cause of Cholangitis.

BACKGROUND Cholecysto-hydatid fistula is a rare complication of liver echinococcosis; suppurative cholangitis due to cholecysto-hydatid fistula is even rarer. A multidisciplinary approach is required by radiology and surgery departments during the preoperative diagnosis and treatment processes of these cases. In this paper, a patient treated with suppurative cholangitis due to cholecysto-hydatid fistula is presented. CASE REPORT A 76-year-old female patient was admitted to emergency services due to cholangitis. Abdominal computerized tomography (CT) examination revealed that the common bile duct was dilated through the right liver in a wide and torsional pattern; the gallbladder cleaved into hepatic flexura and its wall became irregular. There was a cystic appearance 10×13×12 cm in size on the lateral segment of the left liver lobe. Endoscopic retrograde cholangiopancreatography (ERCP) was performed, and it showed the communication between the hydatid cyst pouch and the bile duct. The patient was taken to open surgery, which confirmed the imaging findings. The gallbladder and the adjacent cyst were excised, and a T-tube was placed in the choledochus. Postoperative recovery was uneventful. CONCLUSIONS We suggest that cholecysto-hydatid fistula is a severe problem that requires close workup with both the radiology and surgery departments. Preoperative ERCP is beneficial for the visualization of the fistulization between gallbladder and hydatid cyst and for the treatment of suppurative cholangitis.

Management of liver hydatid cyst with cystobiliary communication and acute cholangitis: a 27-year experience.

PURPOSE: The rupture of the hydatid cyst into the bile ducts is a common and serious complication. The rupture can be latent or revealed after a complication such as acute cholangitis. The objective of this study was to discuss the clinical features, radiographic findings, and surgical treatment of this rare complication. METHODS: A retrospective analysis of patients operated for acute cholangitis caused by hydatid cyst between January 1990 and May 2016 was conducted. RESULTS: Our study included 55 cases of acute cholangitis caused by ruptured hydatid cyst: 35 were men and 20 were women. Five patients had medical history of hydatid cyst. On imaging, all patients had a dilated bile duct. In 51 cases, there was a single hydatid cyst. Hydatid cysts with fistula were located in the right lobe of the liver in 49 cases and in the left lobe in 6 cases. Seven patients underwent an emergency surgery after admission, while others were operated after 3-8 days. A conservative procedure associated with drainage was applied in 49 cases. Endoscopic treatment was performed in four cases which failed in two cases. Twenty-eight cases developed postoperative complications, among which the most common complication was biliary fistula (n - 17). There were eight cases of postoperative deaths (14.5%). CONCLUSIONS: Liver hydatid cyst with cystobiliary communication and superadded acute cholangitis is a serious clinical problem requiring the early diagnosis and surgery in the absence of endoscopic therapy.

Manifestation of hydatid cyst of liver with pancreatitis, cholangitis and jaundice: A case report.

Hydatid disease or echinococcosis, a systemic zoonosis is caused by Echinococcusgranulosus larvae. This is a common disease found all over the world, especially in the Mediterranean region. We report a 40 year old male with no known comorbids who came with complaints of fever with rigors and chills, right hypochondriac pain, and yellow discolouration of the sclera. A CT scan abdomen with endoscopic retrograde cholangiopancreatography (ERCP) gave a diagnosis of hydatid cyst of the liver with pancreatitis, cholangitis and jaundice due to involvement of the biliary tree and common bile duct ERCP was done and a stent was placed after which the patient was referred to general surgery department where the resection of cyst was performed under general anaesthesia. Pancreatitis was managed conservatively. We could not find any case reported in the literature, which showed manifestation of hydatid cyst of liver with pancreatitis, cholangitis and jaundice simultaneously, which made us report this case.

Cholangiohydatidosis: an Infrequent Cause of Obstructive Jaundice and Acute Cholangitis.

BACKGROUND: One of the evolutionary complications of hepatic echinococcosis (HE) is cholangiohydatidosis, a rare cause of obstructive jaundice and cholangitis. The aim of this study was to describe the results of surgical treatment on a group of patients with cholangiohydatidosis and secondary cholangitis in terms of post-operative morbidity (POM). MATERIAL AND METHOD: Case series of patients operated on for cholangiohydatidosis and cholangitis in the Department at Surgery of the Universidad de La Frontera and the Clínica Mayor in Temuco, Chile between 2004 and 2014. The minimum follow-up time was six months. The principal outcome variable was the development of POM. Other variables of interest were age, sex, cyst diameter, hematocrit, leukocytes, total bilirubin, alkaline phosphatase and transaminases, type of surgery, existence of concomitant evolutionary complications in the cyst, length of hospital stay, need for surgical re-intervention and mortality. Descriptive statistics were calculated. RESULTS: A total of 20 patients were studied characterized by a median age of 53 years, 50.0% female and 20.0% having two or more cysts with a mean diameter of 13.3 ± 6.3 cm. A median hospital stay of six days and follow-up of 34 months was recorded. POM was 30.0%, re-intervention rate was 10.0% and mortality rate was 5.0%. CONCLUSION: Cholangiohydatidosis is a rare cause of obstructive jaundice and cholangitis associated with significant rates of POM and mortality.

Parasitic and infectious diseases of the biliary tract in migrants and international travelers.

INTRODUCTION: In recent years, global and regional crises have led to extraordinary worldwide migration, accompanied by an increase in long-distance travel from Western countries. Both are linked to a rising incidence of rare parasitic and infectious diseases in first world countries, including in the biliary tract. Areas covered: A selective literature research in PubMed was performed to review the most important parasitic and infectious biliary diseases, which are caused by a wide variety of pathogens and may be latent over long periods, with chronic courses leading to cholangitis, hepatic failure or development of cholangiocarcinoma. Parasites such as Ascaris, Fasciola and Clonorchis/Opisthorchis are particularly important and may trigger biliary diseases or predisposition for bacterial superinfections. Viral or protozoal cholangitis is mainly a problem of impaired immunity. Expert commentary: Currently, these entities are still rare in migrants and long-distance travelers. However, a significant increase in Western countries has to be expected. Incidences are most likely underestimated because of protracted clinical latency. Diagnosis depends on the relevant pathogens, the host's immune status and the extent or distribution of biliary obstruction. Modern tomographic methods, ERCP and specific microbiological/parasitological/virological tests are of crucial diagnostic importance. Antimicrobial/antiparasitic/antiviral therapy along with ERCP and interventional sonography/radiology provide effective treatment options.

A combination of liver fluke infection and traditional northeastern Thai foods associated with cholangiocarcinoma development.

Opisthorchis viverrini infection is one of the risk factors for cholangiocarcinoma (CCA) in northeast Thailand, a region with one of the highest reported incidence rates of CCA. The traditional practice of eating raw fish, repeated exposure to liver flukes, and consumption of nitrosamine-contaminated food are major risk factors for CCA. So far, there have been no reports about which northeastern traditional dishes may be involved in CCA development. The present study, thus, investigated the effects of traditional foods. It focused specifically on the consumption of fermented foods in combination with O. viverrini infection in hamsters. Syrian hamsters were divided into six groups: (i) normal hamsters, (ii) O. viverrini infection only and (iii)-(vi) O. viverrini infection plus fermented foods (pla som-fish fermented for 1 day), som wua-fermented beef, som phag-fermented vegetables, and pla ra-fish fermented for 6 months. Syrian hamster livers were used for analysis of histopathological changes through hematoxylin and eosin; Sirius Red; and immunohistostaining for cytokeratin-19, proliferating cell nuclear antigen, and CA19-9. Hamster sera were used for liver and kidney function tests. Results of all O. viverrini-infected groups and fermented food groups showed that histopathological changes consisted primarily of aggregations of inflammatory cells surrounding the hepatic bile duct, especially at the hilar region. However, there was a difference in virulence. Interestingly, aggregations of inflammatory cells, new bile duct formation, and fibrosis were observed in subcapsular hepatic tissue, which correlated to positive immunohistochemical staining and increased liver function test. The present study suggests that fermented food consumption can exacerbate cholangitis and cholangiofibrosis, which are risk factors for cholangiocarcinoma-associated opisthorchiasis.

Liver Hydatid Cyst and Acute Cholangitis: a Case Report.

Amongst the cause of cystic hepatic disease, hydatid cyst is common in the Asia, South America, and Africa. The definitive therapy for hepatic hydatid disease is surgical resection. Rupture of the hydatid cyst into the biliary tree can lead to serious cholangitis. In this report, a 22-year-old man is presented with the signs and symptoms of obstructive jaundice and cholangitis. Ultrasonography reported dilated common bile duct (CBD) with sludge and stones, a hydatid cyst adjacent to the gall bladder and mild thickening of gallbladder wall without a stone. MRCP revealed dilated CBD with a cyst in segment fifth of liver. Due to signs and symptoms of obstructive jaundice in addition to lab data and imaging modalities, the ruptured hydatid cyst into a biliary tree was considered, and surgical intervention was performed to extract daughter vesicles from the CBD. Post intervention, signs and symptoms and cholestasis enzymes were subsided.

Percutaneous Ultrasound-guided Cholecystocentesis and Bile Analysis for the Detection of Platynosomum spp.-Induced Cholangitis in Cats.

BACKGROUND: Examination of bile could be useful to diagnose Platynosomum spp.-induced cholangitis in cats. Obtaining bile via percutaneous ultrasound-guided cholecystocentesis (PUC) is possible but raises safety concerns in cats with severe cholecystitis. OBJECTIVES: The objectives of this study were to investigate the use of PUC to collect bile samples from cats with known platynosomosis and to determine if bile analysis could be a diagnostic test. ANIMALS: Twenty-seven free-roaming cats positive for Platynosomum spp. eggs via fecal examination. METHODS: In this prospective study, fecal egg counts were performed by double centrifugation with Sheather's solution. Bile was collected using PUC from anesthetized cats. Egg counts in bile were performed with a stereoscope. Euthanasia and postmortem examination were performed immediately after PUC. RESULTS: All cats had ultrasound (US) evidence of cholangitis or cholecystitis. Thirty-nine PUCs were performed with 14 cats having 2 PUCs 12 or 24 days apart. Postmortem examinations showed no overt gallbladder damage or leakage but fresh blood was noted in the gallbladder lumen of 3 cats. Median Platynosomum spp. egg counts were higher in bile (1450 eggs/mL; IQR, 400; 5138 eggs/mL) as compared to feces (46 eggs/mL; IQR, 10; 107 eggs/mL) (P < .001). CONCLUSION AND CLINICAL IMPORTANCE: Bile egg count analysis is an alternative method with higher egg counts as compared to fecal egg count analysis for the diagnosis of platynosomosis. Obtaining bile via US guidance is technically feasible and safe in cats with cholangitis/cholecystitis. Cholecystocentesis and bile analysis are especially relevant for those cats with chronic cholangitis/cholecystitis and negative fecal egg counts for Platynosomum.

Intrahepatic Duct Stones Harboring Ascariasis Ova: A Case Report.

Ascariasis lumbricoides is one of the most common helminthic infestations in humans. Despite the fact that the prevalence of ascariasis in developed countries has been decreasing, biliary ascariasis can cause serious complications, such as acute cholangitis, pancreatitis, and liver abscess. Here we presented a rare ascariasis-related complication-hepatolithiasis.A 60-year-old female patient had symptoms of recurrent cholangitis. Abdominal computed tomography scan revealed left intrahepatic duct stones with left liver lobe atrophy. Endoscopic retrograde cholangiopancreatography was performed, but the stones could not be removed due to left main intrahepatic duct stenosis. The patient was treated with left hemi-hepatectomy. Unexpectedly, Ascaris ova were found on the histopathological examination. She received antihelminthic therapy orally and was on regular follow-up without any complications.Our study indicates that clinicians should be aware of biliary ascariasis in patients with hepatolithiasis, though not living in endemic areas.

Rare cause of jaundice in a post liver transplant patient.

A hepatitis B virus carrier suffering from acute flare of chronic hepatitis B infection underwent deceased-donor liver transplantation. He was put on the immunosuppressive agent tacrolimus. On routine follow-up, he was found to have abnormal liver function. Computed tomography scan of the abdomen did not show any dilatation of the biliary system. Liver biopsy showed scattered microabscesses, and a microgranuloma was detected. Endoscopic retrograde cholangiography was performed and a biliary anastomotic stricture (BAS) was noted. In addition, the Chinese liver fluke, Clonorchis sinensis, was discovered. Balloon dilatation and stenting were performed. The patient was given a course of praziquantel. His liver function improved and normalized. We present the case of a liver transplant recipient with cholangitis caused by C. sinensis infestation and infection and biliary obstruction resulting from BAS.

[Acute cholangitis secondary to ascariasis and complicated by liver abscesses]. / Angiocholite aiguë d'origine ascaridienne compliquée d'abcès hépatiques.

Acute cholangitis secondary to ascariasis is rare and occurs mainly in areas of high endemicity. The clinical presentation is non-specific, sometimes complicated by liver abscess. Abdominal ultrasound plays an important role in diagnosis and therapeutic surveillance. We report the case of a 35-year-old Malagasy woman with an acute cholangitis secondary to ascariasis and complicated by liver abscesses and its course to full recovery under medical treatment.
