Biliobronchial fistula after liver surgery for giant hydatid cyst

Pulmonary hydatidosis with hepatopleural fistula: A case report

INTRODUCTION AND IMPORTANCE

Cystic echinococcosis (CE) is a chronic illness caused by the tapeworm Echinococcus granulosus. It is classified as a neglected disease and is a priority according to the World Health Organization. CE is prevalent in populations engaged in specific livestock practices and is associated with poor living conditions.

CASE PRESENTATION

41-year-old female Maasai patient who presented with symptoms of cough, dyspnea, fever, and weight loss. Physical examination and CT scans confirmed the presence of cystic masses in the lungs and liver. The patient underwent a thoracotomy procedure to address complications from a hepato-pleural fistula.

CLINICAL DISCUSSION

Echinococcus is a tropical disease that affects over a million people worldwide annually. It primarily affects communities engaged in animal husbandry and causes the development of hydatid cysts. Diagnosis can be challenging due to prolonged asymptomatic periods. In rare cases, cysts can rupture into the pleura and bronchial tree, causing respiratory symptoms. Surgical treatment involves the systematic evacuation of cysts and visceral cyst excision, with concurrent laparotomy and thoracotomy being the optimum approach.

CONCLUSION

Hydatid cysts remain a significant health problem, particularly when large pleural cysts occur with subphrenic liver cysts. Surgical intervention, specifically a single-stage thoracotomy, is the preferred first-line treatment. This approach allows for both cysts to be addressed in a single procedure, providing effective and efficient treatment to patients.

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.

Bilioptysis associated with alcohol hepatitis without evidence of bronchobiliary fistula: A rare case report

The presence of bilirubin in the sputum is uncommon but, when present, is most commonly associated with the presence of bronchobiliary fistula, which could be associated with a number of underlying conditions. However, the finding of bilioptysis without bronchobiliary fistula is uncommon, with one associated mechanism postulated to involve increased capillary membrane permeability. This case report describes a patient presenting with bilioptysis while being medically managed with prednisolone for severe alcoholic hepatitis. The patient developed hospital-acquired pneumonia during her hospitalization associated with bilioptysis, resulting in progressive respiratory failure requiring ventilatory support. Alcohol-related pulmonary dysfunction alters pulmonary immune processes, leading to increased susceptibility to pulmonary infection and disrupting the basal alveolar epithelial membrane, thus increasing permeability. This patient's findings were in the absence of a bronchobiliary or bronchopleural fistula, and we hypothesize that increased capillary membrane permeability was contributory to the bilioptysis in this case.

Broncho-biliary fistula secondary to biliary obstruction and lung abscess in a patient with pancreatic neuro-endocrine tumor

We present a case report of broncho-biliary fistula that developed due to the blockage of biliary stent placed during the management of pancreatic neuroendocrine tumor (pNET); diagnosed on high clinical suspicion, percutaneous cholangiogram and contrast enhanced computed tomography (CECT); and successfully treated with percutaneous transhepatic biliary drainage (PTBD).
