Liver-Specific Contrast-Enhanced Magnetic Resonance Cholangio-Pancreatography (Ce-MRCP) in Non-Invasive Diagnosis of Iatrogenic Biliary Leakage

Current non-invasive diagnostic modalities of iatrogenic bile leak (BL) are not particularly sensitive and often fail to localise the BL origin. Percutaneous transhepatic cholangiography (PTC) and endoscopic retrograde cholangiopancreatography (ERCP) are considered the gold standard, yet are invasive studies with potential complications. Ce-MRCP has been not comprehensively studied in this setting but may prove particularly helpful given its non-invasive nature and the anatomical dynamic detail. This paper reports a monocentric retrospective study of BL patients referred between January 2018 and November 2022 submitted to Ce-MRCP followed by PTC. The primary outcome was the accuracy of Ce-MRCP in detecting and localising BL compared to PTC and ERCP. Blood tests, coexisting cholangitis features and time for leak resolution were also investigated. Thirty-nine patients were included. Liver-specific contrast-enhanced MRCP detected BL in 69% of cases. The BL localisation was 100% accurate. Total bilirubin above 4 mg/dL was significantly associated with false negative results of Ce-MRCP. Ce-MRCP is highly accurate in detecting and localising BL, but sensitivity is significantly reduced by a high bilirubin level. Ce-MRCP may be very useful in early BL diagnosis and in accurate pre-treatment planning, but can only be reliably used in selected patients with TB < 4 mg/dL. Non-surgical techniques, both radiological and endoscopic, are proven to be effective in terms of leak resolution.

Implementation of Blockchain Technology Could Increase Equity and Transparency in Organ Transplantation: A Narrative Review of an Emergent Tool

In the last few years, innovative technology and health care digitalization played a major role in all medical fields and a great effort worldwide to manage this large amount of data, in terms of security and digital privacy has been made by different national health systems. Blockchain technology, a peer-to-peer distributed database without centralized authority, initially applied to Bitcoin protocol, soon gained popularity, thanks to its distributed immutable nature in several non-medical fields. Therefore, the aim of the present review (PROSPERO N° CRD42022316661) is to establish a putative future role of blockchain and distribution ledger technology (DLT) in the organ transplantation field and its role to overcome inequalities. Preoperative assessment of the deceased donor, supranational crossover programs with the international waitlist databases, and reduction of black-market donations and counterfeit drugs are some of the possible applications of DLT, thanks to its distributed, efficient, secure, trackable, and immutable nature to reduce inequalities and discrimination.

Non-Operative Management of Bronchobiliary Fistula Due to Proximal Migration of Biliary Stent in a Patient With Unresectable Klatskin Tumor

Introduction:

One of the methods for the biliary tree decompression in the case of Klatskin tumor is transpapillary stenting, which could be completed by stent migration in 4% to 10% of cases. Approximately half of the stent migrations are in the proximal direction. In this study, we reported a rare case of proximal trans-diaphragmatic stent migration to the lower lobe of the right lung with the formation of a biliary-bronchial fistula (BBF).

Case presentation:

A 60-year-old woman was diagnosed with hilar cholangiocarcinoma (type 3B by Bismuth-Corlette) complicated by posthepatic jaundice. To relieve jaundice there were performed endoscopic retrograde cholangiopancreatography, endoscopic sphincterotomy, endobiliary stent placement (10 Fr, 150 mm). A restenting (11.5 Fr, 130 mm) was performed in 2.5 months due to endobiliary tube occlusion. In the next 2 months, coughing attacks and biliptysis have appeared in the patient. A CT scan showed penetration of the liver, diaphragm, and lower lobe of the right lung with the proximal part of the stent and caused BBF formation. Anti-inflammatory and antibacterial therapy was administrated for 14 days and BBF was closed. Stent retrieval from the right hemithorax and endobiliary restenting was performed in 9 months after primary stenting. During follow-up, appropriate positioning and functioning of the stent were observed.

Conclusion:

BBF formation is a rare complication of endobiliary stenting, which can be successfully treated by anti-inflammatory and antibiotic therapy, followed by transpapillary stent retrieval.

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.

Broncho-hepatico-cutaneous fistula in a case of amoebic liver abscess

Pulmonary complications occur in 7-20% of patients with amoebic liver abscess(ALA) and may present as pleural effusion, empyema, lung abscess or a bronchohepatic fistula. Rupture into a bronchus presents as sudden coughing with expectoration of chocolate-coloured sputum and is usually managed by postural drainage, bronchodilators and anti-amoebic drugs. A young boy presented with a large amoebic liver abscess of about 1 L volume which ruptured into the lung. He required surgical drainage of the liver abscess as even after intubation he was not able to maintain adequate ventilation. Following this he developed a broncho-hepatico-cutaneous fistula with drainage of 400-500 mL bile per day and bubbling of air in the abdominal drain. He underwent selective right hepatic duct cannulation with endo-papillotomy, following which the fistula closed gradually.

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.

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.

Bronchobiliary fistula successfully treated with n-butyl cyanoacrylate via a bronchial approach

A bronchobiliary fistula is an abnormal communication between the biliary tree and the airway that can result in debilitating amounts of bilioptysis, or bile-stained sputum. The authors present an approach for the conservative management of a bronchobiliary fistula in a patient who failed traditional conservative therapy and refused surgical intervention.

Percutaneous interventional therapy of persistent biliary fistulas

BACKGROUND

Persistent biliary leakage is a challenging problem when conservative treatment methods fail. We present our experience with alternative percutaneous radiologic interventions to seal refractory biliary leaks.

METHODS

From April 1998 to December 2005, a retrospective analysis of 23 patients with biliary leakage revealed six patients who were unresponsive to drainage were treated with use of Histoacryl (n = 5), microcoils (n = 2), or covered stent (n = 2) alone or in various combinations.

RESULTS

In all patients, the biliary leakage ceased following a single procedure. Distally migration of microcoils into the abscess cavity was observed in a one coiling procedure, which was clinically insignificant. In one patient treated with covered stent, in-stent restenosis was seen in the postprocedural second year, which required another intervention. No recurrence of fistula was noted in the follow-up period (ranging from 6 to 47 months).

CONCLUSIONS

Persistent biliary fistulas can be treated successfully by means of various percutaneous radiological interventions that can decrease the morbidity associated with prolonged external drainage and avert the need for surgery. We recommend superselective embolization, preferably with Histoacryl, for a safe and effective control of leakage. Although restenosis after stenting remains problematic, covered stents should be reserved as a feasible alternative for selected cases.
