Bronchobiliary fistulas in adults

Hepato-thoracic cystic echinococcosis transit. Clinical features, postoperative complications and hospital mortality. A systematic review

BACKGROUND

Hepato-thoracic hydatid transit (HTT) is an evolutionary complication of hepatic cystic echinococcosis. This study aimed to report the available evidence regarding postoperative complications (POC) and hospital mortality (HM).

METHODS

Systematic review. Studies related to HTT were included. Searches were performed in Trip Database, SciELO, BIREME-BVS, WoS, PubMed, EMBASE and SCOPUS.

PRIMARY OUTCOMES

POC and HM.

SECONDARY OUTCOMES

publication date, origin and designs, number of patients, cyst type, hospital stance, treatments; and methodological quality (MQ) of studies applying MInCir-T and MInCir-Pr2 scales. Descriptive statistics, weighted means (WM) and their comparison using least squares logistic regression, and meta-analysis of prevalence of POC and HM were applied.

RESULTS

604 studies were retrieved (101 met selection criteria, representing 1020 patients). WM age: 42.6 years, 58.3 % male. Reports are mainly from Spain (19.8 %) and Turkey (17.8 %). With a WM of 18.3 days of hospital stance, it was verified 28.9 % of POC, 12.6 % needed re-interventions, and 9.7 % died. MQ of studies: 9.1 ± 1.9 (MInCir-T) and 13.2 ± 2.9 (MInCir-Pr2). Comparing the behavior of variables in two periods (1983-2002 vs. 2003-2024), statistically significant differences were observed in POC, HM, and reinterventions.

CONCLUSION

HTT is associated with high POC, and significant HM, despite the passage of time.

Bronchobiliary Fistulas

A bronchobiliary fistula (BBF) is a rare condition that occurs from an abnormal communication between the biliary tree and bronchial airway. Historically, BBFs resulted as complications from certain traumas, malignancy, or infection; however, iatrogenic etiology is becoming more common in the setting of advancing therapeutics. We present two such cases of patients with bronchobiliary fistulas and subsequent treatment that arose after medical treatment for underlying malignancies. Due to there being no current guidelines on the treatment approach for bronchobiliary fistulas, a literature review spanning over forty years was performed to identify treatment modalities and etiologies documented in the past. The review showed that regardless of the underlying cause of the BBF, a dual therapy approach or multi-modal therapy approach had a higher rate of success than a single intervention approach.

Thoracobilliary fistula as a rare complication of Roux-en-Y cholangio-jejunostomy stricture after iatrogenic bile duct injury correction: A case report

INTRODUCTION

Thoracobiliary fistula is a rare presentation of biliary obstruction which is secondary to anastomotic Roux-en-Y cholangiojejunostomy stricture.

CASE PRESENTATION

A 52-year-old man presented with fever, fatigue, and anorexia. He was jaundiced. He had a history of a laparoscopic cholecystectomy complicated by iatrogenic bile duct injury which was corrected by Roux-en-Y cholangiojejunostomy. The CT revealed a subphrenic abscess. Therefore, we established CT-directed percutaneous drainage and antibiotics treatment. Four months later, he presented again with fever, fatigue, and jaundice. He also complained of bilioptysis. Pleurocentesis revealed a deep yellow pleural fluid. Thoracobiliary fistula was suspected. Our patient underwent a right thoracotomy where we drained bile, performed pleural decortication, and excised the damaged portion of the right lower pulmonary lobe. We also inserted a subphrenic drain. The fistula was remained to close spontaneously and the patient had a good postoperative recovery.

DISCUSSION

The obstruction of the bile ducts leads to the retention of bile proximal to the obstruction site, the formation of a liver biloma, and subsequently the abscess formation. By increasing, the abscess gradually erodes the diaphragm. A presence of adhesions between the lower lung lobe and the diaphragm will lead the abscess to erode directly into the lung parenchyma until it reaches the nearest bronchus and a BBF is formed.

CONCLUSION

The presence of bile in the pleural space due to pleurobiliary fistula, or bilioptysis due to bronchobiliary fistula are rare presentations. However, they are serious conditions that may follow bile duct operations. They require early recognition and intervention.

Bronchobiliary fistula after stenting of biliary duct as the management of iatrogenic bile duct injury during elective cholecystectomy

BACKGROUND

Bronchobiliary fistula is a rare and complex entity defined by an abnormal communication between the biliary and bronchial systems. The etiopathogenesis is not completely understood, but the most common factors implicated are hepatobiliary tumors, biliary obstruction, iatrogenic damage or trauma.

METHODS

Here we present a case of a 69-year-old man that developed a bronchobiliary fistula and a pulmonary abscess after migration of a bile duct stent placed as part of the treatment of an iatrogenic bile duct injury that occurred during elective cholecystectomy.

RESULTS

A conservative approach, that included broad-spectrum antibiotic, removal of the stent, and sphincterotomy, was enough for the closure of the fistula and resolution of the symptoms.

CONCLUSION

We emphasize the importance of prompt recognition of this entity and a concerted therapeutic strategy to optimize the probability of success, avoiding the destructive consequences of the bile in the pulmonary parenchyma and septic complications.

Case Series of MRI and CT Assessment of Acquired Hepato-Biliary and Pancreatic Transdiaphragmatic Fistulae

Transdiaphragmatic fistulae are rare conditions characterized by pathological communication between two epithelium-lined surfaces. Hepato-thoracic fistula consists of abnormal communication between the liver and/or the biliary system and the thorax; while the pancreaticopleural fistula consists of abnormal communication between the pancreas and the thorax, the pleuro-biliary fistula represents the more common type. Clinical symptoms and laboratory findings are generally non-specific (e.g., thoracic and abdominal pain, dyspnea, cough, neutrophilia, elevated CPR, and bilirubin values) and initially, first-level investigations, such as chest RX and abdominal ultrasound, are generally inconclusive for the diagnosis. Contrast-enhanced CT represents the first two-level radiological imaging technique, usually performed to identify and evaluate the underlying pathology sustained by transdiaphragmatic fistulae, their complications, and the evaluation of the fistulous tract. When the CT remains inconclusive, other techniques such as MRI and MRCP can be performed. A prompt and accurate diagnosis is crucial because the recognition of fistulae and the precise definition of the fistulous tract have a major impact on the management acquisition process.

Case report: Biliobronchial fistula after biliary tract stenosis

Biliobronchial fistula (BBF) is a rare abnormality resulting from congenital or acquired communication between the bile ducts and the bronchial tree. Patients often suffer from chronic cough, dyspnea, and bilioptysis, a pathognomonic symptom of this condition. Conservative methods such as less-invasive procedures are gradually consolidating. Nonetheless, surgery remains the primary treatment, especially in more complex cases. We present the case of a 44-year-old woman with a chronic cough, no verified periods of fever, cyclic jaundice, and episodes of yellowish sputum. She had undergone cholecystectomy in 2018 and had been hospitalized several times since for pneumonia treatment. All consequent investigations for mycobacteriosis were negative. When referred to our hospital, she had cyclic jaundice and parenchymal consolidation in the right lower lobe. Suspected bilioptysis motivated the search for a biliobronchial fistula. Magnetic resonance cholangiography (MRC) confirmed stenosis of the biliary tract and fistulous path, and sputum analysis indicated high bilirubin levels. External biliary bypass was performed as an initial conservative and definitive therapy due to the presence of liver cirrhosis. Although BBF is a rare condition when bilioptysis is suspected, a diagnostic investigation should be initiated. Our case study proposes two criteria for diagnosis: an imaging exam demonstrating the fistulous path and confirmation of bilirubin in the sputum or bronchoalveolar lavage (BAL). When diagnosed, surgical correction should be performed.

Percutaneous Treatment of Bronchobiliary Fistula: Report of a Successful Transhepatic Embolization and a Decision-Making Strategy Driven by Systematic Literature Review

Bronchobiliary fistula is a rare condition characterized by bile leaking into the bronchial tree causing biliptysis. It may arise from liver infection or as a consequence of resection and thermal ablation of cancer. Currently, there is no consensus about the treatment strategy. Surgery is considered the main therapy by most authors. However, this systematic literature review shows that the success rate of percutaneous treatments may reach 75%. Adding to such evidence, we also report the case of a woman affected by iatrogenic bronchobiliary fistula secondary to liver thermal ablation, successfully treated with percutaneous drainage plus embolization. Summarizing these results, we encourage the percutaneous management of bronchobiliary fistula by providing a 3-step decision-making algorithm, aimed at reducing the need for major surgery.

Bronchopleurobiliary fistula following right lower lobectomy in a patient with prior hepatic abscess: a case report

In a 68-year-old male patient with cholangitis microabscess in the liver, cavitary lung cancer of the right lower lobe was incidentally diagnosed. The patient’s medical history comprised totally laparoscopic distal gastrectomy (TLDG) and cholecystectomy 9 years ago. Before TLDG, endoscopic retrograde cholangiopancreatography (ERCP) was performed because of a common bile duct stone and cholangitis. Three months ago, he was readmitted with cholangitic microabscess, and a cavitary lesion of right lower lobe was detected incidentally. Hepatobiliary microabscess was improved with ERCP and antibiotic treatment. Video-assisted thoracoscopic surgery (VATS) right lower lobectomy and mediastinal lymph node dissection were undergone uneventfully. Pneumonic infiltration in the right lower lung field and hydropneumothorax on the right side were developed on postoperative day 10. Chest computed tomography showed pneumobilia and micro-bronchopleural fistula (BPF) was suspected with bronchoscopic examination. Despite antibiotics usage and thoracic suction, air leakage could not be improved. VATS Talc pleurodesis was performed on postoperative day 38. Contralateral pneumonia developed 1 week following talc pleurodesis. Furthermore, bilirubin was detected in the repeated bronchial washing and pleural fluid and they showed the same color and nature. Though ERCP and endoscopic nasobiliary drainage, the patient’s condition deteriorated and the patient passed away on postoperative day 60. Bronchopleurobiliary fistula is an extremely rare complication after thoracic surgery for which surgical treatment is challenging, early recognition of a developing fistula and the aggressive treatment at an early stage can reduce the associated morbidity and mortality from the sequelae of this rare disease entity.

The development of broncho-biliary fistula after treatment for hepatocellular carcinoma: a report of two cases

Broncho-biliary fistula (BBF) is a rare but severe disorder defined as abnormal communication between the biliary system and bronchial tree. Cases of BBF have occasionally been reported, but no standard treatment has been established. We report two cases of BBF that developed after the treatment of hepatocellular carcinoma (HCC) and reviewed the relevant literature. Case 1, a man in his early eighties was diagnosed with BBF 4 months after undergoing surgical resection for HCC (diameter, 7 cm; location, segments 4 and 5). Percutaneous drainage and endoscopic nasobiliary drainage (ENBD) improved BBF without recurrence for more than a year. Case 2, a woman in her late sixties was diagnosed with BBF after percutaneous radiofrequency ablation for HCC. Although the BBF was treated with ENBD, bronchial occlusion, and percutaneous transhepatic portal vein embolization, these treatments were unsuccessful and the patient died. Although non-invasive treatments have been developed, refractory BBF still exists. The prediction of BBF and the development of more effective treatments are necessary to improve outcomes.

Bronchobiliary fistula after hepatectomy: A case report and review of the literature

Bronchobiliary fistula (BBF) is a rare complication following hepatectomy, and consists of an abnormal intercommunication between the biliary tract and bronchial tree. The management of this rare entity is challenging with limited current evidence to date on how to treat this condition. Herein, a case of BBF following a central hepatectomy and the successive steps of the management was presented. Fourteen months postoperatively, the patient presented to the Oncology Department complaining of new onset fever and expectoration. A computerized tomography scan revealed a BBF and the patient was subsequently referred to our department for further treatment. The surgical team decided that a further operation was required. Using the transabdominal approach, a communication between the initial intrahepatic collection and one inferior lobular bronchus was revealed. Transhiatal removal of fistula was performed with closure of the defect through the abdomen. There was no bile leak through the remaining liver parenchyma. Multidisciplinary management should be considered, taking into consideration the underlying pathology leading to this rare complication. Conservative treatment should be considered first, while surgical resection of the BBF remains an option when other therapies have failed. Surgeons should be aware of this rare complication bile duct injuries during hepatic operations can cause.

Bronchobiliary fistula after ramucirumab treatment for advanced gastric cancer: A case report

BACKGROUND

Bronchobiliary fistula (BBF) is a rare disease characterized by an abnormal connection between the biliary system and bronchi. Traditional causes of BBF include trauma and infections, and more recent causes include malignancies and certain cancer treatments. Ramucirumab is an antivascular endothelial growth factor receptor 2 monoclonal antibody, currently used as a second-line treatment for gastric cancer.

CASE SUMMARY

A 43-year-old man visited our hospital with the complaint of jaundice. He was diagnosed with inoperable advanced gastric cancer owing to invasion of the hepatic hilum by the tumor. After percutaneous transhepatic biliary drainage (PTBD) and stent placement, capecitabine and oxaliplatin were administered as first-line palliative chemotherapy. The tumor progressed, and paclitaxel and ramucirumab were administered as second-line chemotherapy. However, on the first day of the second cycle, the patient suddenly developed dyspnea and pneumonia. BBF was diagnosed on the basis of the presence of bilious sputum and the results of computed tomography, and PTBD was repeated.

CONCLUSION

This is the first report of BBF after administration of the new antiangiogenic agent ramucirumab.

Anesthetic management for a patient with bronchobiliary fistula after pancreaticoduodenectomy: A case report

RATIONALE

Perioperative management of patients with bronchobiliary fistula (BBF) is an anesthetic challenge because they typically exhibit poor lung function preoperatively, require meticulous lung isolation intraoperatively and need postoperative respiratory support.

PATIENT CONCERNS

A 44-year-old man with a past surgical history of pancreaticoduodenectomy presented fluctuating fever, jaundice, dyspnea and yellowish sputum. Despite intravenous antibiotic treatment and repeated percutaneous drainage, patient showed gradual deterioration with hypoxemia, and uncontrolled pneumonia.

DIAGNOSES

The patient was diagnosed with BBF based on the clinical manifestation such as biloptysis with pneumonia, and imaging studies.

INTERVENTIONS

Resection of the fistula and bilobectomy was performed under general anesthesia. Avoidance of positive pressure ventilation before lung isolation and precise lung isolation are essential for patients with BBF to protect the unaffected lung. Therefore, rapid sequence induction was performed. Left-sided double-lumen tube was inserted for lung isolation and position of the tube was confirmed by visualization with fiberoptic bronchoscopy. Bile-stained secretion was repeatedly suctioned in trachea and both bronchi during surgery.

OUTCOMES

In spite of decrease in SpO2 with institution of one-lung ventilation, the patient's oxygenation was gradually improved as surgery progressed without hemodynamic instability. At the end of surgery, the double-lumen tube was replaced with a single-lumen endotracheal tube for postoperative mechanical ventilation.

LESSONS

Absolute lung isolation using double-lumen tube for one-lung ventilation and bronchial toilet during surgery and replacement of single-lumen tube for postoperative respiratory support at the end of surgery are effective to improve oxygenation in patients with BBF.

Hepatopulmonary Fistula in a Colorectal Cancer Patient

Cancer patients with liver metastasis may be candidates for liver surgery and local interventional techniques as part of their treatment. Although rare in this setting, hepatopulmonary fistula has been described as a possible complication. The clinical picture may be atypical, and, without specific treatment, it usually has a dismal prognosis. As locoregional treatments (whether interventional or surgical techniques) in liver neoplasms are being more frequently used we need to include this entity as a possible differential diagnosis of local liver treatment complications.

Post-traumatic bronchobiliary fistula

Post-traumatic bronchobiliary fistula (BBF) is a rare entity, with only a few cases reported worldwide. Bilioptysis is pathognomonic of the condition, however, bronchoscopy and bronchoalveolar lavage along with CT are used for confirmation. We describe this condition in a young woman who presented to us with bilioptysis following a laparotomy for blunt torso trauma. Diagnosis was made of BBF, followed by surgical management and complete recovery. We emphasise the signs of early diagnosis, confirmatory tests, individualised treatment and advocate surgical management as the gold standard of treatment.

Two cases of bronchobiliary fistula: Case report

A bronchobiliary fistula, or a biliobronchial fistula (BBF), is a rare condition. It results from an abnormal connection between the biliary and bronchial trees, and is characterized by pathognomonic bilious sputum with suspicious pneumonia. Traditionally, an infectious disease, such as a hydatid infection, has been known to cause a BBF, but BBFs have recently become associated with tumors. In every case, procedures and treatments differ between centers, from simple conservative management to invasive surgical procedures. This case report presents two patients who had BBF after liver resection. Symptoms of each patients were treated and controlled successfully by percutaneous transhepatic biliary drainage tube insertion. We hope that this report helps in the management of BBF in other cases.

Hepatic Echinococcosis with Thoracic Involvement. Clinical Characteristics of a Prospective Series of Cases

INTRODUCTION

Thoracic involvement (TIHE) is one of the evolutionary complications of hepatic echinococcosis (HE).

AIM

The aim of this study was to describe the clinical characteristics and postoperative morbidity (POM) of a series of patients with TIHE treated surgically.

MATERIAL AND METHODS

Series of cases of patients treated for TIHE between 2000 and 2014 in the Hospital Regional and Clínica Mayor in Temuco, Chile, with a minimum 12-month follow-up. The outcome variable was "development of POM". Descriptive statistics were used.

RESULTS

The series was composed of 37 patients with a mean age of 53.2 ± 47.4 years (51.4% female). Mean cyst diameter was 19.4 ± 15.5 cm, and 75.7% of the lesions were located in the right hepatic lobe. The most frequent surgical technique used for the cyst was subtotal pericystectomy (56.8%); the residual cavity was treated by capitonnage (27.0%) or omentoplasty (21.6%), and a phrenoplasty with or without prosthetic material was performed for the TIHE. Mean hospital stay was 6.0 ± 5.7 days and follow-up was 61.4 ± 79.9 months; a mortality rate of 2.7% (one patient) and a POM of 24.3% (9 patients) were verified.

CONCLUSION

TIHE is an uncommon evolutionary complication of HE associated with significant POM rate.

Successful endoscopic management of a persistent bronchobiliary fistula with Histoacryl®/Lipiodol® mixture

Introduction A bronchobiliary fistula (BBF) following liver directed therapy (resection/ablation) is a rare complication in which an abnormal communication between the biliary tract and bronchial tree is formed. This case report describes the successful management of a persistent BBF following multiple liver wedge resections and microwave ablation in a patient with a metastatic neuroendocrine tumour of the terminal ileum. Case history A 69-year-old man presented with unexplained weight loss and was subsequently diagnosed with a neuroendocrine tumour of the terminal ileum and liver metastasis. Following elective right hemicolectomy and multiple bilobar liver wedge resections combined with liver microwave ablation, he developed an early bile leak. A month later, a right subphrenic collection was identified and four months following surgery, biloptysis was noted. Numerous attempts with endoscopic retrograde biliary drainage (ERBD) failed to achieve sufficient drainage. The patient was treated successfully with endoscopic injection of a mixture of Histoacryl® glue (B Braun, Sheffield, UK) and Lipiodol® (Guerbet, Solihull, UK). There was no evidence of the BBF one year following intervention. Conclusions This novel approach for persistent BBF management using endoscopic Histoacryl® glue embolisation of the fistula tract should be considered either as an adjunct to ERBD or when biliary tract decompression by drainage and/or sphincterotomy fails, prior to proceeding with surgical interventions.

Bronchobiliary fistula after multiple transcatheter arterial chemoembolizations for hepatocellular carcinoma: A case report

Bronchobiliary fistula (BBF) is a rare condition, defined as an abnormal communication between the bronchial system and the biliary tree. Patients with this condition usually present with massive biliptysis, and the mortality rate is high. BBF has been reported to occur in patients with congenital conditions, complications of trauma, hepatic abscesses and biliary tract obstruction (surgical as well as non-surgical). However, to the best of our knowledge, BBF as a complication of transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) has not been reported to date. We herein report a case of BBF developing as a complication following TACE in a 71-year-old male patient with HCC. The patient was treated by placement of a metallic biliary stent followed by percutaneous transhepatic biliary drainage to decompress the intrahepatic biliary tree, and his symptoms were immediately relieved.

Combined thoracic and hepatobiliary surgery for iatrogenic bronchobiliary fistula

Bronchobiliary fistula is a rare pathology mainly caused by hepatic tumors, bile duct obstruction, or hepatic hydatid disease. A 70-year-old man developed a bronchobiliary fistula after biliary stenting. After failure of conservative treatment including endoscopic retrograde biliary drainage, he underwent a combined operation with a two-level approach. Both a thoracotomy and laparotomy were performed, allowing pulmonary resection, diaphragmatic repair, and bile duct reconstruction during the same operation. Postoperative follow-up at one year showed optimal healing of the fistula.

A Case Report of the Anesthetic Management for Liver Retransplantation in a Patient With a Bronchobiliary Fistula

A 64-year-old woman with a previous liver transplant developed graft failure with biliary complications including a bronchobiliary fistula, which did not respond to preoperative conservative therapy. Liver retransplantation provided definitive therapy for the liver failure and bronchobiliary fistula. We present anesthestic considerations for the intraoperative management of a liver retransplant with one-lung ventilation.

Usefulness of Tc99m-mebrofenin Hepatobiliary Scintigraphy and Single Photon Emission Computed Tomography/Computed Tomography in the Diagnosis of Bronchobiliary Fistula

Bronchobiliary fistula (BBF), a rare complication of liver disease, is an abnormal communication between the biliary tract and bronchial tree. BBF may occur as a consequence of local liver infections such as hydatid or amebic disease, pyogenic liver abscess or trauma to the liver, obstruction of biliary tract, and tumor. As such management of liver disease with BBF is very difficult and often associated with a high rate of morbidity and mortality. Therefore, timely diagnosis of BBF is imperative. Hepatobiliary scintigraphy along with hybrid single photon emission computed tomography/computed tomography using Tc99m-mebrofenin is a very useful noninvasive imaging modality, in the diagnosis of BBF.

Bronchobiliary fistula caused after hepatectomy for hepatocellular carcinoma: a case report

Background

A bronchobiliary fistula, an intercommunication between the biliary tract and bronchial trees, is an extremely rare complication after hepatectomy.

Case presentation

A 70-year-old male underwent partial resection of the liver for recurrent hepatocellular carcinoma under a thoracoabdominal approach. The immediate postoperative clinical course was uneventful, but the patient was febrile and laboratory examinations revealed leukocytosis on the 15th postoperative day. An intraabdominal abscess was suspected based on the computed tomography findings, and percutaneous drainage was performed. Bile was drained, and fluoroscopy using a contrast medium from the drainage tube revealed a communication between the cavity and the common hepatic duct. Two weeks after drainage, bilioptysis was seen. Fistulography demonstrated the presence of the bronchus in the right lower lobe of the lung via the subphrenic space. Therefore, the patient was diagnosed to have a bronchobiliary fistula. Fistulography revealed closure of the communication with the bronchus about a month after drainage. However, the bile leakage and bilioptysis did not stop even after endoscopic nasogastric biliary drainage, and ethanol injection therapy were performed. Eventually, residual right bisectionectomy without resection of the fistulous tract and involved lung was performed to remedy the intractable bile leakage. The clinical course after the reoperation was good without bile leakage, bilioptysis, or pulmonary disorders, and the patient was discharged 40 days after reoperation.

Conclusions

We experienced a rare case of bronchobiliary fistula that occurred after hepatectomy for hepatocellular carcinoma. Careful attention should be paid to prevent bile leakage during hepatectomy, since bile leakage has the potential to cause a bronchobiliary fistula.

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).

Brocho-biliary fistula: A rare complication after ruptured liver abscess in a 3½ year old child

Bronchobiliary fistula (BBF) is a rare condition, defined by the presence of abnormal communication between biliary tract and bronchial tree. We describe a 3½-year-old child who developed BBF after rupture of liver abscess. She underwent exploratory laparotomy and peritoneal wash for ruptured liver abscess. Seven months later she presented with fever and cough with yellow-colored expectoration (bilioptysis). An abnormal communication between right branch of the hepatic duct and a branch of right main bronchus was identified. Child underwent right lateral thoracotomy and right lower lobectomy with surgical excision of sinus tract. On follow-up child was asymptomatic and doing well.

Intraductal papillary mucinous neoplasm of the liver: GI image

Intraductal papillary mucinous neoplasms (IPMNs) are rare, mucin-producing, predominantly noninvasive tumors arising from epithelial cells. Most IPMNs arise from the pancreas. There exists a subset of IPMN of the biliary tract (BT-IPMN). IPMNs regardless of origin produce large amounts of mucin relative to scant amounts of epithelial cells, leading to mass effect disturbances in bile flow. Affected bile ducts exhibit marked dilatation. The majority of IPMN patients present with a non-malignant neoplasm. Because of potential for transformation, surgery is the treatment of choice. Bronchobiliary fistulas can present as congenital defects, following thoracoabodominal trauma, or as rare complications of diseases of the biliary tract such as BT-IPMN. There are no reported cases in the literature of bronchobiliary fistula associated with BT-IPMN, but there is a clear theoretical risk.

Congenital tracheobiliary fistula in an adolescent patient

Congenital tracheobiliary fistula is a rare malformation that allows communication between the respiratory system and hepatobiliary tract. We describe a male adolescent patient who was admitted with a destroyed lung caused by repetitive bile pneumonitis with a congenital tracheobiliary fistula. Left pneumonectomy was performed, and the fistula tract was successfully divided.

The challenging management of hepatopulmonary fistulas

Hepatopulmonary fistula although benign in nature carries an unacceptable mortality risk up to 10.3% in some case series mainly due to surgical complications. From the first description by Ferguson and Burford in 1967 till present different approaches have been applied and with the introduction of less invasive techniques the results have significantly improved. Interestingly the prevalence of the different etiological factors has changed over the years especially with the advance of liver ablating techniques and surgery. A step by step approach to this entity, from diagnosis to treatment has to be reestablished in order to identify the role of interventional modalities and to develop a management algorithm.

Unusual complications of gallstones

Extrinsic compression of the bile duct from gallstone disease is associated with bilio-biliary fistulization, requiring biliary-enteric reconstruction. Biliary-enteric fistulas are associated with intestinal obstruction at various levels. The primary goal of therapy is relief of intestinal obstruction; definitive repair is performed for selected patients. Hemobilia from gallstone-related pseudoaneurysms is preferentially controlled by selective arterial embolization. Rapidly increasing jaundice with relatively normal liver enzymes is a diagnostic hallmark of bilhemia. Acquired thoraco-biliary fistulas are primarily treated by percutaneous and endoscopic interventions.

Thoracobiliary fistulas: literature review and a case report of fistula closure with omentum majus

Background

Thoracobiliary fistulas are pathological communications between the biliary tract and the bronchial tree (bronchobiliary fistulas) or the biliary tract and the pleural space (pleurobiliary fistulas).

Review of the literature

We have reviewed aetiology, pathogenesis, predilection formation points, the clinical picture, diagnostic possibilities, and therapeutic options for thoracobiliary fistulas.

Case report

A patient with an iatrogenic bronchobiliary fistula which developed after radiofrequency ablation of a colorectal carcinoma metastasis of the liver is present. We also describe the closure of the bronchobiliary fistula with the greater omentum as a possible manner of fistula closure, which was not reported previously according to the knowledge of the authors.

Conclusions

Newer papers report of successful non-surgical therapy, although the bulk of the literature advocates surgical therapy. Fistula closure with the greater omentum is a possible method of the thoracobiliary fistula treatment.

Successful percutaneous management of bronchobiliary fistula after radiofrequency ablation of metastatic cholangiocarcinoma in a patient who has a postoperative stricture of hepaticojejunostomy site

Bronchobiliary fistula (BBF) is a rare condition that is defined as an abnormal communication between the biliary system and bronchial tree. Furthermore, a BBF is an extremely rare complication of radiofrequency ablation (RFA). A 54 year-old man with a history of extrahepatic biliary cancer had been suffering with a benign stricture of hepaticojejunostomy site and was treated with RFA for metastatic cholangicarcinoma. In this report, we describe a patient with BBF complicated by an abscess which occurred after RFA. He was treated by placement of external drainage catheter into the liver abscess and percutaneous transhepatic biliary drainage (PTBD) into the right intrahepatic duct. After 6 weeks, a complete obliteration of the BBF was confirmed by a repeated follow-up of computed tomography scan and cholangiography through PTBD.

Biliobronchial fistula after liver surgery for giant hydatid cyst

Background. Biliobronchial fistula (BBF) is a rare complication in the natural history of liver hydatid disease by Echinococcus granulosus. We present a case of BBF after resection of a giant liver hydatid cyst in a 72-year-old woman. Case Report. A total cystpericystectomy was done, leaving the left lateral section of the liver that was fixed to the diaphragm. Postoperatively, the patient developed obstructive jaundice. An ERCP showed an obstruction at the junction of the left biliary duct and the main biliary duct and contrast leak. At reoperation, the main duct was ischemic, likely due to torsion along its longitudinal axis. A hepatotomy was done at the hilar plate, and the biliary duct was dissected and anastomosed to a Roux-en-Y jejunal loop. She was discharged without complications. Five months later, the patient developed cholangitis and was successfully treated with antibiotics. However, she suffered repeated respiratory infections, and four months later she was admitted to the hospital with fever, cough, bilioptysis, and right lower lobe pneumonia. The diagnosis of BBF was confirmed with ^99mTc Mebrofenin scintigraphy. At transhepatic cholangiography, bile duct dilation was seen, with a biliothoracic leak. She underwent dilatation of cholangiojejunostomy stricture with placement of an external-internal catheter. The catheter was removed 3.5 months later, and two years later the patient remains in very good condition. Conclusion. An indirect treatment of the BBF by percutaneous transhepatic dilation of the biliary stenosis avoided a more invasive treatment, with satisfactory outcome.

Management of acquired bronchobiliary fistula: A systematic literature review of 68 cases published in 30 years

AIM: To outline the appropriate diagnostic methods and therapeutic options for acquired bronchobiliary fistula (BBF).

METHODS: Literature searches were performed in Medline, EMBASE, PHMC and LWW (January 1980-August 2010) using the following keywords: biliobronchial fistula, bronchobiliary fistula, broncho-biliary fistula, biliary-bronchial fistula, tracheobiliary fistula, hepatobronchial fistula, bronchopleural fistula, and biliptysis. Further articles were identified through cross-referencing.

RESULTS: Sixty-eight cases were collected and reviewed. BBF secondary to tumors (32.3%, 22/68), including primary tumors (19.1%, 13/68) and hepatic metastases (13.2%, 9/68), shared the largest proportion of all cases. Biliptysis was found in all patients, and other symptoms were respiratory symptoms, such as irritating cough, fever (36/68) and jaundice (20/68). Half of the patients were treated by less-invasive methods such as endoscopic retrograde biliary drainage. Invasive approaches like surgery were used less frequently (41.7%, 28/67). The outcome was good at the end of the follow-up period in 28 cases (range, 2 wk to 72 mo), and the recovery rate was 87.7% (57/65).

CONCLUSION: The clinical diagnosis of BBF can be established by sputum analysis. Careful assessment of this condition is needed before therapeutic procedure. Invasive approaches should be considered only when non-invasive methods failed.

Uncommon acquired fistulae involving the digestive system: summary of data

PURPOSE

Most gastrointestinal fistulae commonly occur following surgery. A minority is caused by a myriad of other etiologies and is termed by some as "uncommon fistulae". The aim of this study was to review these fistulae and their treatment.

METHODS

A literature review was carried out. Searches were conducted in Pubmed and related references reviewed.

RESULTS

Except for Crohn's disease and diverticulitis, "uncommon fistulae" are described in case reports or very small case series. Most of the patients were treated by surgery.

CONCLUSIONS

The anatomic features of the fistula and the etiology usually dictate the approach. Most patients will eventually need surgery to resolve this pathology.

Retained drains causing a bronchoperitoneal fistula: a case report

Abstract

Conclusion

To the best of our knowledge, this is the first known case report of a bronchoperitoneal fistula caused by retained surgical drains. This is also the first known report that details successful management of this condition with advanced ventilatory techniques. This case highlights the importance of follow-up for trauma patients since retained surgical drains have the potential to cause life-threatening complications. When faced with this condition, clinicians should be aware of advanced ventilatory methods that can be employed in the intensive care unit. In this case, these techniques proved to be life-saving.

A case of biliopleural fistula in a patient with hepatocellular carcinoma

BACKGROUND

A 66-year-old white man with a history of cryptogenic cirrhosis complicated by hepatocellular carcinoma, ascites and hepatic encephalopathy presented with a productive cough and pleuritic chest pain on his right side. He underwent transarterial chemoembolization for hepatocellular carcinoma 6 months before presentation. The patient had a history of coronary artery disease, type 2 diabetes mellitus and hypertension.

INVESTIGATIONS

Medical history and physical examination, laboratory investigations, diagnostic thoracentesis, bacterial culture and Gram staining studies, abdominal MRI with magnetic resonance cholangiopancreatography, endoscopic retrograde cholangiopancreatography, infused chest CT and examination of the thorax during open thoracotomy.

DIAGNOSIS

Biliopleural fistula with connections between the right pleural space and a branch of the right intrahepatic biliary tree.

MANAGEMENT

Antibiotics, placement and removal of a chest tube, endoscopic retrograde cholangiopancreatography to guide biliary sphincterotomy with placement and removal of a hepatic-duct stent, open thoracotomy with decortication, percutaneous transhepatic cholangiography and placement of a catheter.

Detection of a suspected bronchobiliary fistula by hepatobiliary scintigraphy

Bronchobiliary fistula (BBF) represents a rare but severe complication in patients affected by liver metastases. Although a clinical suspicion can arise when specific clinical signs, in particular biliptysis, are present, conventional imaging modalities often fail to confirm the diagnosis. We present a case of a patient affected by colon cancer with liver metastases previously treated with partial right-sided hepatectomy and multiple thermo-ablative treatments combined with chemotherapy, who manifested a septic fever associated with productive cough and biliptysis. Diagnosis of BBF was confirmed only by hepatobiliary scintigraphy with (99m)Tc-heptoiminodiacetic acid.

Management of acquired bronchobiliary fistula: 3 case reports and a literature review

Bronchobiliary fistula (BBF), which often presents with bilioptysis, is an abnormal communication between the bronchial system and biliary tree. It is a complication associated with a high mortality rate and requires a well-planned management strategy. Although hydatid disease is still the leading cause, extensive surgical interventions and invasive procedures of the liver have altered the profile of patients in recent decades. This paper presents 3 cases of BBF and reviews the literature regarding the treatment options generally mandated by clinical presentation and the underlying disease.

Successful treatment of intractable bronchobiliary fistula using long-term biliary stenting

A bronchobiliary fistula (BBF) is an uncommon entity with bilioptysis being a pathognomonic sign. We describe the case of a 41-year-old man who had recurrent BBF, 6 months after resection of the anterior segment of the right lower pulmonary lobe and repair of a BBF due to hepatic hydatid disease. Magnetic resonance cholangiography revealed a communication between the biliary tree and the lower lobe of the right lung. Endoscopic biliary sphincterotomy and repeated insertion of large size biliary plastic stents led to a successful resolution of the symptoms and closure of the fistula.
