Fascioliasis: A Rare Parasitic Infection-Mimicking Tumor in the Liver: Report of Two Cases.

Fascioliasis is a rarely encountered parasitic infection in Turkey that mainly affects the liver and bile ducts. Other defined localizations of the parasite are the lungs, gastrointestinal system, and subcutaneous fatty tissue. Two cases of female patients who presented to the hospital with abdominal pain and whose physical examination and laboratory findings were normal except peripheral eosinophilia, were detected to have liver masses with necrotic areas. Segmental hepatectomies were performed in both cases with the preliminary diagnosis of liver tumors. Upon microscopic examinations of the resection materials, necrotic granulomatous inflammation with eosinophilic reaction at the periphery and the parasite (Fasciola hepatica) were seen. Both cases were reported to be fascioliasis according to these findings. Two cases of fascioliasis mimicking malignancy in the liver are presented here together with literature findings.

Fasciola hepatica in the common bile duct: spyglass visualization and endoscopic extraction.

We report the case of a 60-year-old Peruvian female who was admitted with abdominal pain and jaundice. Cholangioscopy revealed a leaf-like trematode, Fasciola hepatica. This trematode was extracted with a Dormia's basket via endoscopic retrograde cholangiopancreatography (ERCP).

First case report of retroperitoneal metastasis of fascioliasis after surgery.

RATIONALE: Fascioliasis is a rare cause of liver abscesses, and its clinical course consists of hepatic phase and biliary phase. PATIENT CONCERNS: We describe a 58-year-old female patient who presented with a 2-month history of intermittent fever and abdominal pain. An abdominal computed tomography (CT) revealed confluent low-density lesions in the liver. Complete surgical resection of these abscesses was performed, and postoperative pathological examination and serological tests confirmed a diagnosis of fascioliasis. However, 4 months after the surgery, follow-up CT revealed a lesion in the retroperitoneal area. Meanwhile, ultrasonography-guided percutaneous needle biopsy of the retroperitoneal lesion was performed, and a parasitic infection was suspected. DIAGNOSES: Retroperitoneal metastasis of hepatic phase fascioliasis. INTERVENTIONS: The patient received parasitic resistance treatment with triclabendazole at a dose of 10 mg/kg/d for 2 consecutive days. OUTCOMES: After 2 courses of triclabendazole therapy, the retroperitoneal metastasis regressed to a minor lesion. LESSONS: To the best of our knowledge, this is the first case report of retroperitoneal metastasis of fascioliasis, aimed at helping recognize the clinical features and treatment options of this rare disease.

Biliary Fasciola gigantica infestation in a nonendemic area--An intraoperative surprise.

A 7year old girl infected with the zoonotic trematode, Fasciola gigantica is reported because of the extreme rarity of this condition in our region. Because of the overlap in symptomatology and radiological features, the more common amebic/pyogenic liver abscess in the initial hepatic migratory phase and later choledochal cyst/biliary ascariasis when the parasite was finally located in the extrahepatic bile ducts, were thought of delaying effective treatment. The diagnosis was confirmed only by surgical exploration. The characteristic contrast enhanced computed tomography scan features retrospectively identified were multiple clustered hypodense lesions in the liver with peripheral enhancement in the acute hepatic migratory phase, and periportal tracking in the previously affected areas of the liver with biliary dilatation and a linear hypointense lesion within the common bile duct in the chronic phase. Although a known association, she did not have eosinophilia. This child, who became symptomatic at the age of 5.5years, also appears to be one of the youngest patients reported with Fasciola gigantica.

Cholestasis caused by Fasciola gigantica.

Fascioliasis is an infectious disease caused by the hepatic trematodes Fasciola hepatica and Fasciola gigantica. Here, we report the case of Fasciola gigantica presenting with biliary obstruction and abdominal pain that was diagnosed and treated by endoscopic retrograde cholangiography (ERCP). A 46-year-old woman presented with right upper quadrant abdominal pain and jaundice. Physical examination revealed icterus and hepatomegaly. Laboratory findings revealed an increase in liver transaminases and bilirubin. Abdominal ultrasonography showed extrahepatic and intrahepatic bile duct dilatation. The patient underwent ERCP. One live Fasciola gigantica was removed from the common bile duct by ERCP. In conclusion, fascioliasis should be considered in the differential diagnosis of obstructive jaundice, especially in endemic regions, and it should be kept in mind that ERCP plays an important role in the diagnosis and treatment of these patients. To our knowledge, this is the second case report of Fasciola gigantica treated by ERCP in Turkey.

[Endoscopic removal by ERCP of Fasciola hepatica alive: two case reports and review of the literature]. / Extracción endoscópica por CPRE de Fasciola hepática viva: reporte de dos casos y revisión de la literatura.

We report two cases of biliary fascioliasis in patients from the highlands of Peru; with several months of symptoms characterized for biliary-type pain, dark urine and jaundice in one case. Both of them referred to the department of Gastroenterology of the Hospital Nacional Guillermo Almenara Irigoyen for suspicious of choledocolithiasis. Laboratory tests were performed which showed variable high levels of functional liver tests (cholestasis) and marked eosinophilia in one case. Magnetic resonance cholangiography (CRMN) was performed and then informed as an apparent image of biliary stone in choledocus in both cases. Endoscopic retrograde cholangiopancreatography (ERCP) was performed and after sphincterotomy, one flattened, lanceolate parasite, with active mobility morphologically compatible with Fasciola hepatica was extracted. After the ERCP antiparasitic treatment was given with triclabendazole. Clinical outcome was favourable.

Extracción endoscópica por CPRE de Fasciola hepática viva: reporte de dos casos y revisión de la literatura / Endoscopic removal by ERCP of Fasciola hepatica alive: two cases report and review of the literature

Presentamos dos casos de fascioliasis crónica en pacientes procedentes de la zona andina del Perú, con sintomatología de varios meses de evolución, con dolor tipo biliar, coluria e ictericia en uno de los casos. Ambos referidos al Servicio de Gastroenterología del Hospital Nacional Guillermo Almenara Irigoyen para estudio por sospecha de colédocolitiasis. Se les realizó exámenes de laboratorio que mostraban aumentos variables en las pruebas de función hepática (colestasis) y en uno de ellos eosinofilia marcada. Se realizó colangioresonancia magnética (CRMN) en ambos casos demostraron imagen sugestiva de cálculo en colédoco. La pancreatocolangiografía retrograda endoscópica (CPRE) fue realizada y luego de esfinterotomía, se extrajo un parásito aplanado, lanceolado, con movilidad activa morfológicamente compatible con Fasciola hepática en ambos casos. Posterior a la CPRE se inició tratamiento antiparasitario con triclabendazol, siendo la evolución clínica favorable.

Sporadic incidence of Fascioliasis detected during hepatobiliary procedures: a study of 18 patients from Sulaimaniyah governorate.

BACKGROUND: Fascioliasis is an often-neglected zoonotic disease and currently is an emerging infection in Iraq. Fascioliasis has two distinct phases, an acute phase, exhibiting the hepatic migratory stage of the fluke's life cycle, and a chronic biliary phase manifested with the presence of the parasite in the bile ducts through hepatic tissue. The incidence of Fascioliasis in Sulaimaniyah governorate was unexpected observation. We believe that shedding light on this disease in our locality will increase our physician awareness and experience in early detection, treatment in order to avoid unnecessary surgeries. FINDINGS: We retrospectively evaluated this disease in terms of the demographic features, clinical presentations, and managements by reviewing the medical records of 18 patients, who were admitted to the Sulaimani Teaching Hospital and Kurdistan Centre for Gastroenterology and Hepatology. Patients were complained from hepatobiliary and/or upper gastrointestinal symptoms and diagnosed accidentally with Fascioliasis during hepatobiliary surgeries and ERCP by direct visualization of the flukes and stone analysis. Elevated liver enzymes, white blood cells count and eosinophilia were notable laboratory indices. The dilated CBD, gallstones, liver cysts and abscess were found common in radiological images. Fascioliasis diagnosed during conventional surgical CBD exploration and choledochodoudenostomy, open cholecystectomy, surgical drainage of liver abscess, ERCP and during gallstone analysis. CONCLUSION: Fascioliasis is indeed an emerging disease in our locality, but it is often underestimated and ignored. We recommend the differential diagnosis of patients suffering from Rt. Hypochondrial pain, fever and eosinophilia. The watercress ingestion was a common factor in patient's history.

Living Fasciola hepatica in biliary tree: a case report.

Here we report a rare case of living Fasciola hepatica in biliary tract. The patient was in acute phase of infection and treated successfully with 10 mg/kg oral triclabendazole after the fluke was extracted using endoscopic retrograde cholangiopancreatography (ERCP).

A case of ectopic intraabdominal fascioliasis presented with acute abdomen.

Human fascioliasis with Fasciola species occurs worldwide and is most common among rural people who tend sheep and eat uncooked water vegetables, particularly watercress. The natural history of the acute phase begins with ingestion of metacercariae encysted on various kinds of aquatic vegetation such as watercress. Fascioliasis primarily involves the liver, bile ducts, gallbladder, and occasionally ectopic sites. We describe herein a case of ectopic fascioliasis. This uncommon form of disease was peritonitis; both visceral and parietal peritoneal layers were affected with the formation of multiple nodules and ascites.

Laparoscopy-assisted right hepatectomy in a case of Fasciola hepatica.

Laparoscopic hepatectomy provides the usual advantages of a minimally invasive surgery. This study presents a case of Fasciola hepatica infection that was successfully treated with laparoscopic hepatectomy. The patient was referred because of persistent fever and right hypochondralgia with a huge mass occupying the right lobe of the liver, which was detected by imaging analysis. Serologic tests indicated an F. hepatica infection. The patient underwent a laparoscopic resection because the anthelmintic agent, triclabendazole was not effective. During the surgical technique, 5 trocars were inserted. After liver mobilization, the Glissonian pedicles and right hepatic veins were safely taped. A Penrose drain was placed behind the liver for a liver-hanging maneuver. A liver parenchymal transection was performed through an 8 cm handport site using a dissecting sealer (TissueLink Medical) after precoagulating its superficial layer by microtaze. Glissonian pedicles and the right hepatic vein were divided using an endolinear stapler (endcutter 45, Ethicon). Finally, the resected specimen was extracted from the handport. The surgical time was 450 minutes and the surgical blood loss was 370 mL. The patient was discharged 10 days after the surgery with an uneventful postoperative course. The laparoscopy-assisted hepatectomy in this case was beneficial for the patient's quality of life as a minimally invasive operation with a high degree of safety.

Endoscopic management of biliary parasitic diseases.

UNLABELLED: AIM/MATERIALS AND METHODS: Between January 2000 and June 2007, 3,548 endoscopic retrograde cholangiopancreatography (ERCP) were performed for extrahepatic cholestasis, cholangitis, and choledocholithiasis. The results of ERCPs were evaluated retrospectively and examined carefully to investigate the management and endoscopic therapy of biliary parasites. RESULTS: Of the 3,548 patients who underwent ERCP, 24 (0.66%) were found to have biliary parasitosis. The mean age of the biliary parasitosis patients (16 women) was 48.6 (15-77) years. Of these 24 cases, 16 patients had hydatid cystic disease (eight with partial obstruction of the biliary tract, and eight with ruptured cysts), four patients had Fasciola hepatica, and four patients had Ascaris lumbricoides infestation. Endoscopic sphincterotomy was performed, after which the choledochus was examined carefully by balloon catheter and basket procedure. CONCLUSION: The ERCP procedure is very useful in the therapy of biliary parasitic infestations.

Parásitos de fasciola hepática intracoledociano / Common bile duct fasciolasis: report of one case

La fasciolasis es una enfermedad parasitaria producida por el tremátodo digeneo Fasciola hepática. Durante la fase crónica de la enfermedad los parásitos pueden entran en los conductos biliares, y ser causa de ictericia obstructiva, colangitis, pancreatitis y otras complicaciones. Se presenta el caso clínico de una paciente intervenida por sospecha de colelitiasis y colédocolitiasis, a la cual durante la exploración coledociana intraoperatoria le fueron extraídos múltiples parásitos adultos de Fasciola hepática. Este hallazgo sólo fue aclarado posteriormente en la biopsia diferida. Se realiza una revisión breve del tema, métodos de diagnóstico, tratamiento médico y alternativas quirúrgicas de tratamiento.

Fasciolasis is a zoonotic disease caused by the digenean trematode Fasciola hepatica. During the chronic phase of the disease the parasites invade the main biliary ducts, causing obstructive jaundice, cholangitis, pancreatitis and other complications. We report a 75 years old female, operated due to the suspicion of a choledocholithiasis. During the exploration of the choledochus, adult F. hepatica parasites were extracted. The pathology report of the parasites confirmed the diagnosis.

Fasciola hepatica in a New Zealander traveler.

Fascioliasis is a reemerging zoonosis endemic in many parts of the world. Reports of imported fascioliasis by migrants into nonendemic countries are common, but tourists and business travelers are rarely afflicted. Here, we report a case of a New Zealander traveler who acquired the infection on a business trip.

Surgery in Fasciola hepatica pancreatitis: report of a case and review of literature.

Fasciola hepatica is a trematode rarely causing disease in humans. In symptomatic cases, while various pathologies such as damage to liver parenchyma, acute cholecystitis, and obstructive jaundice can be seen, the development of pancreatitis is rarely mentioned in the literature. The treatment of the disease is medical. In cases where no definite diagnosis can be made or in incidental cases where common bile duct exploration is being done, F. hepatica can be detected accidentally during operation. No consensus has yet been reached on the surgical procedure to be applied in this condition. We report on our case due to the rare occurrence of pancreatitis as a complication. In surgical cases, external drainage of the bile is both crucial in observing the response to the treatment, and also should be accepted as part of the treatment.

Diagnosis of fasciola hepatica cases in an operating room.

Fascioliasis is a zoonotic disease that is acquired by ingestion of the metacercaria form on uncooked aquatic plants, and humans act as an accidental host. Diagnosis is confirmed by the demonstration of the parasites or evidence of them in faeces and serology. In the absence of these data, delays or misdiagnosis may occur since it may mimic many diseases. In this study, we present three cases, among them two were similar to the above-mentioned statement. The first case, to the best of our knowledge, is the first case with adult-type living fluke in the gall bladder, diagnosed by laparoscopic cholecystectomy.

[Common bile duct distomatosis managed by coelioscopic aproach. One case report]. / Distomatose de la voie Biliaire principale traitée par voie coelioscopique. A propos d'un cas.

Biliary distomatosis is caused by a parasitis of trematode family: the fascialo hepatica. It is a rare affection in Tunisia. The diagnostic is often done in the status phase. Adult parasite stay preferentially at biliary ducts, cause obstruction and cholangitis. The authors report a case of biliary treated successfully by laparoscopic procedure.

Therapeutic endoscopic retrograde cholangiopancreatography for the treatment of Fasciola hepatica presenting as biliary obstruction.

Human infection with the Fasciola hepatica liver fluke is a rare cause of biliary obstruction, especially within the United States. Humans can become accidental hosts of this parasite by ingesting contaminated drinking water or plants. Symptoms during the acute phase include fever, right upper quadrant pain, eosinophilia, and hepatomegaly. During the chronic stage of infection, the parasite may remain asymptomatic for many years. This article presents a case of biliary obstruction due to Fasciola hepatica that was diagnosed and treated successfully with endoscopic retrograde cholangiopancreatography.
