Complicated Liver Cystic Echinococcosis-A Comprehensive Literature Review and a Tale of Two Extreme Cases.

Cystic echinococcosis is a zoonotic parasitic disease that affects the liver in more than 70% of cases, and there is still an underestimated incidence in endemic areas. With a peculiar clinical presentation that ranges from paucisymptomatic illness to severe and possibly fatal complications, quality imaging and serological studies are required for diagnosis. The mainstay of treatment to date is surgery combined with antiparasitic agents. The surgical armamentarium consists of open and laparoscopic procedures for selected cases with growing confidence in parenchyma-sparing interventions. Endoscopic retrograde cholangiopancreatography (ERCP) is extremely useful for the diagnosis and treatment of biliary fistulas. Recent relevant studies in the literature are reviewed, and two complex cases are presented. The first patient underwent open surgery to treat 11 liver cysts, and during the follow-up, a right pulmonary cyst was diagnosed that was treated by minimally invasive surgery. The second case is represented by the peritoneal rupture of a giant liver cyst in a young woman who underwent laparoscopic surgery. Both patients developed biliary fistulas that were managed by ERCP. Both patients exhibited a non-specific clinical presentation and underwent several surgical procedures combined with antiparasitic agents, highlighting the necessity of customized treatment in order to decrease complications and successfully cure the disease.

Broncho biliary fistula following interventional radiology for hepatic metastases.

Bronchobiliary fistulas are defined as an abnormal communication between the biliary system and the bronchial tree. They are extremely rare complications of radiofrequency or microwave ablation. A 39-year-old woman with a history of neuroendocrine pancreatic carcinoma suffering from liver metastasis was treated with microwave ablation (MWA). In this case report, we present a case of intractable biliptysis from a bronchobiliary fistula secondary to an MWA. The patient was diagnosed by endoscopic retrograde cholangiopancreatograph and hepatobiliary scintigraphy. Treatment involved a right hemihepatectomy, a redo-hepaticojejunostomy, and the surgical placement of a transhepatic drain. After 6 weeks of drain placement, this could be removed. The fistula was thus successfully treated.

Traumatic biliary fistula with bile duct disconnection.

A 43-year-old man was admitted to our department for accident. Computed tomography (CT) scan revealed low-density shadows in the hepatogastric and peripancreatic space. The patient still has abdominal pain after the performation of CT-guided abdominal puncture and drainage. Magnetic Resonance Cholangiopancreatography (MRCP) showed that the middle and lower segments of common bile duct were stricture and truncature. Endoscopic bile duct catheterization and drainage showed that the lower segment was dislocated and disconnected. Then the doctor used the balloon and contrast agent to pressurize, and at the same time, the distal common bile duct was pulled by the mirror, trying to straighten the common bile duct, changing its axial direction, and try to bridge it repeatedly by using the guide wire of misgurnus anguillicaudatus. The patient significantly improved over the next 3 days. After 11 months of follow-up, the patient came to our hospital to remove the biliary stent,and has no abdominal pain anymore.

[Spontaneous cholecysto-cutaneous fistula: about two cases]. / Fístula colecisto-cutánea espontánea: a propósito de dos casos.

Cholecysto-cutaneous fistula (CCF) is a rare complication of untreated biliary pathology, with fewer than 100 cases documented in the literature. Most are secondary to bacterial infection, although it has also been described in gallbladder adenocarcinoma and post trauma. Its clinical presentation is variable, being able to present systemic affection, and its most frequent external drainage site is in the right hypochondrium. Due to the low incidence of this pathology, and the variety of forms of presentation, its management does not have, to date, standardized bases. We present two cases of patients who consulted in the emergency room at the Hospital Nacional de Clínicas for presenting cholecysto-cutaneous fistula. The treatment of both was surgical.

La fístula colecisto-cutáneas (FCC) es una rara complicación de la patología biliar no tratada, habiendo menos de 100 casos documentados en la literatura. La mayoría son secundarias a infección bacteriana, aunque también fue descripta en el adenocarcinoma de vesícula y posterior a traumatismo. Su presentación clínica es variable, pudiendo presentar afección sistémica, y su sitio más frecuente de drenaje externo es en hipocondrio derecho. Debido a la baja incidencia de esta afección, y a la variedad de formas de presentación, su manejo no tiene hasta el momento bases estandarizadas. Presentamos dos casos de pacientes que consultaron por guardia de urgencias en el Hospital Nacional de Clínicas por presentar fistula colecisto-cutánea. El tratamiento de ambos fue quirúrgico.

Cholecystogastric fistula diagnosed by endoscopic ultrasonography.

A case of a patient with symptoms of gastric obstruction secondary to cholecystogastric fistula is presented and a brief review of the literature is done.

Fístula colecistoduodenal sin migración de cálculo: reporte de caso / Cholecystoduodenal fistula without gallstones migration: case report / Fístula colecistoduodenal sem migração de cálculos: relatório de caso

El síndrome de Bouveret es una causa infrecuente de íleo biliar, posee una elevada morbimortalidad. Se produce por la migración de un cálculo, generalmente de gran tamaño, hacia el tracto gastrointestinal a través de una fistula colecistoduodenal. El objetivo de esta carta científica es presentar un paciente con un estadio previo de la enfermedad donde la fistula se encuentra constituida, pero sin migración del cálculo, por lo que el diagnóstico oportuno tendría un impacto favorable en el tratamiento y pronóstico debido a que no se encuentra instaurado el cuadro obstructivo intestinal.

Bouveret's syndrome is a rare cause of biliary ileus, with a high morbimortality. It is caused by the migration of a stone, usually large, into the gastrointestinal tract through a cholecystoduodenal fistula. The objective of this scientific letter is to present a patient with a previous stage of the disease where the fistula is constituted, but without migration of the calculus, so that the timely diagnosis would have a favorable impact on the treatment and prognosis because the obstructive intestinal condition is not established.

A síndrome de Bouveret é uma causa rara de íleo biliar com uma morbilidade e mortalidade elevadas. É causada pela migração de uma pedra, geralmente grande, para o tracto gastrointestinal através de uma fístula colecystoduodenal. O objectivo desta carta científica é apresentar um doente com uma fase anterior da doença em que a fístula está presente, mas sem migração da pedra, para que o diagnóstico atempado tenha um impacto favorável no tratamento e prognóstico, uma vez que a condição obstrutiva instestinal não está estabelecida.

Spontaneous cholecystocutaneous fistula secondary to xanthogranulomatous cholecystitis: a case report.

BACKGROUND: Xanthogranulomatous cholecystitis, a rare variant of cholecystitis, may infrequently be complicated by spontaneous cholecystocutaneous fistula. CASE PRESENTATION: We report the case of a 75-year-old Saudi Arabian man who presented with "a painful area of redness" (cellulitis) over his right upper abdomen. Abdominal computed tomography revealed multiple collections, which were drained surgically. A discharging sinus was identified, and a fistulogram revealed cholecystocutaneous fistula during his follow-up visit. The patient underwent laparoscopic management and recovered uneventfully. Final histopathological evaluation confirmed acute-on-chronic xanthogranulomatous cholecystitis . CONCLUSIONS: Although rare, surgeons should consider cholecystocutaneous fistula in the differential diagnosis of anterior abdominal wall abscesses, particularly in patients with concurrent or background symptoms of gallbladder disease. We report the first case of laparoscopic management for cholecystocutaneous fistula in Saudi Arabia.

Special presentation of bronchobiliary fistula after transcatheter arterial chemoembolization: A case report.

RATIONALE: Transcatheter arterial chemoembolization (TACE) is a widely adopted treatment for advanced stage hepatocellular carcinoma (HCC). Nevertheless, several complications may occur, such as hepatic artery injury, nontarget embolization, pulmonary embolism, hepatic abscess, biloma, biliary strictures, and hepatic failure. However, bronchobiliary fistula is rarely mentioned before. PATIENT CONCERNS: A 65-year-old man with HCC underwent the TACE procedure, and then he encountered fever, dyspnea, abdominal pain, and abundant yellowish purulent bronchorrhea. DIAGNOSIS: Bronchobiliary fistula was diagnosed based on the computed tomography (CT) scan of his chest, which revealed the right lower lobe of his lung was connected to a hepatic cystic lesion. INTERVENTIONS: Percutaneous transhepatic cystic drainage was performed, and we obtained yellowish bile, showing the same characteristics as the patient's bronchorrhea. OUTCOMES: We kept drainage of his biloma and provided supportive care as the patient wished. Unfortunately, the patient passed away due to progressive right lower lobe pneumonia 2 weeks later. LESSONS: This case exhibits a typical CT scan image that was helpful for the diagnosis of post-TACE bronchobiliary fistula. Post-TACE bronchobiliary fistula formation hypothesis includes biliary tree injuries with subsequent biloma formation and diaphragmatic injuries. Moreover, the treatment of bronchobiliary fistula should be prompt to cease pneumonia progression. Therefore, we introduce this rare complication of post-TACE bronchobiliary fistula in hopes that future clinicians will keep earlier intervention in mind.
