Presentation and management of delayed bronchopleural fistula after pulmonary lobectomy: a case report.

BACKGROUND: Lung cancer is the second most diagnosed cancer and the leading cause of cancer deaths worldwide. Surgical lung resection is the best treatment modality in the early stages of lung cancer as well as in some locally advanced cases. Postoperative air leak is one of the most common complications after pulmonary resection with incidence ranging between 20 and 33%. The majority of air leaks seal, within 5 days after surgery, on their own by conservative management. However, at least 5% of patients still have prolonged air coming out from the residual lung at discharge. This report describes the management of a thin lady with right lung cancer who underwent a right lower lobectomy and then suffered from a delayed air leak 7 weeks after surgery and required extensive thoracic and general surgery collaboration. CASE PRESENTATION: A 72-year-old heavy smoker female patient diagnosed with stage I lung cancer underwent right robotic-assisted thoracoscopic surgery converted to thoracotomy because of a fused fissure, right lower lobectomy, and mediastinal lymphadenectomy presented with delayed air leak 49 days after surgery. VATS decortication and mechanical pleurodesis were done 2 weeks after unsuccessful conservative treatment. Still, the lung failed to expand four weeks later so the patient was sent to surgery; she is underweight (BMI of 18) with not many options for a big flap to fill the chest cavity empty space. Accordingly; the decision was to use multiple pedicle flaps; omentum, intercostal muscle, and serratus anterior muscle to cover the bronchopleural fistulas and fill the pleural space in addition to mechanical and chemical pleurodesis. Full expansion of the lung was obtained. The patient was discharged on Post-Operative day 5 without remnant pneumothorax. CONCLUSIONS: Air leaks After lobectomy usually presents directly postoperatively; various management options are available ranging from conservative and minimally invasive to major operative treatment. We presented what we believe was unusual delayed bronchopleural fistula post-lobectomy in a thin lady which demonstrates clearly how a delayed air leak was detected and how collaborative efforts were crucial for delivering high-quality, safe, and patient-centered care till treated and complete recovery.

Treatment of late left bronchopleural fistula after left pneumonectomy through right thoracic approach assisted by extracorporeal membrane oxygenation.

BACKGROUND: Bronchopleural fistula (BPF) is a rare but fatal complication after pneumonectomy. When a BPF occurs late (weeks to years postoperatively), direct resealing of the bronchial stump through the primary thoracic approach is challenging due to the risks of fibrothorax and injury to the pulmonary artery stump, and the surgical outcome is generally poor. Here, we report a case of late left BPF following left pneumonectomy successfully treated using a right thoracic approach assisted by extracorporeal membrane oxygenation (ECMO). CASE PRESENTATION: We report the case of a 57-year-old male patient who underwent left lower and left upper lobectomy, respectively, for heterochronic double primary lung cancer. A left BPF was diagnosed at the 22nd month postoperatively, and conservative treatment was ineffective. Finally, the left BPF was cured by minimally invasive BPF closure surgery via the right thoracic approach with the support of veno-venous extracorporeal membrane oxygenation (VV-ECMO). CONCLUSIONS: Advanced BPF following left pneumonectomy can be achieved with an individualized treatment plan, and the right thoracic approach assisted by ECMO is a relatively simple and effective method, which could be considered as an additional treatment option for similar patients.

[Retrospective Study of Bronchoscopic Intervention Therapy for Bronchopleural Fistula Induced by Pulmonary Surgery].

BACKGROUND: As a new technique developed in recent years, bronchoscopic intervention therapy has the advantages of minimal invasion, high safety and repeatability. The aim of this study is to investigate the clinical characteristics of bronchopleural fistula (BPF) induced by surgeries for lung malignancies or benign diseases and the effect of bronchoscopic intervention therapy for BPF, so as to provide support for prevention and treatment of BPF. METHODS: Data 64 patients with BPF who were treated by bronchoscopic intervention in Respiratory Disease Center of Dongzhimen Hospital, Beijing University of Chinese Medicine from June 2020 to September 2023 were collected. Patients with fistula diameter ≤5 mm were underwent submucous injection of macrogol, combined with blocking therapy with N-butyl cyanoacrylate, medical bioprotein glue or silicone prosthesis. Patients with fistula diameter >5 mm were implanted with different stents and cardiac occluders. Locations and characteristics of fistulas were summarized, meanwhile, data including Karnofsky performance status (KPS), shortbreath scale (SS), body temperature, pleural drainage volume and white blood cell count before and after operation were observed. RESULTS: For all 64 patients, 96 anatomic lung resections including pneumonectomy, lobectomy and segmentectomy were executed and 74 fistulas occurred in 65 fistula locations. The proportion of fistula in the right lung (63.5%) was significantly higher than that in the left (36.5%). Besides, the right inferior lobar bronchial fistula was the most common (40.5%). After operation, KPS was significantly increased, while SS, body temperature, pleural drainage volume and white blood cell count were significantly decreased compared to the preoperative values (P<0.05). By telephone follow-up or readmission during 1 month to 38 months after treament, median survival time was 21 months. 33 patients (51.6%) showed complete response, 7 patients (10.9%) showed complete clinical response, 18 patients (28.1%) showed partial response, and 6 patients (9.4%) showed no response. As a whole, the total effective rate of bronchoscopic intervention for BPF was 90.6%. CONCLUSIONS: BPF induced by pulmonary surgery can lead to severe symptoms and it is usually life-threating. Bronchoscopic intervention therapy is one of the fast and effective therapeutic methods for BPF.

Complex bronchopleural fistulas: a case report.

Bronchopleural fistula (BPF) is a potentially fatal complication and remains a surgical challenge. Concomitant problems, such as pulmonary infection and respiratory failure, are typically the main contributors to mortality from BPF because of improper contact between the bronchial and pleural cavity. We present the case of a 75-year-old male patient with a history of right upper lobe lung cancer resection who developed complex BPFs. Following appropriate antibiotic therapy and chest tube drainage, we treated the fistulas using endobronchial valve EBV placement and local argon gas spray stimulation. Bronchoscopic treatment is the preferred method for patients who cannot tolerate a second surgery because it can help to maximize their quality of life. Our treatment method may be a useful reference for treating complex BPF.

Novel Insights from Clinical Practice Autologous Blood Patch Pleurodesis and Endobronchial Valves for Management of Persistent Air Leaks in Two Cases of Tuberculosis.

INTRODUCTION: Pulmonary infections, such as tuberculosis, can result in numerous pleural complications including empyemas, pneumothoraces with broncho-pleural fistulas, and persistent air leak (PAL). While definitive surgical interventions are often initially considered, management of these complications can be particularly challenging if a patient has an active infection and is not a surgical candidate. CASE PRESENTATION: Autologous blood patch pleurodesis and endobronchial valve placement have both been described in remedying PALs effectively and safely. PALs due to broncho-pleural fistulas in active pulmonary disease are rare, and we present two such cases that were managed with autologous blood patch pleurodesis and endobronchial valves. CONCLUSION: The two cases presented illustrate the complexities of PAL management and discuss the treatment options that can be applied to individual patients.

MSCT study for adult esophageal diverticulum with secondary broncho-esophageal fistula.

BACKGROUND: Broncho-esophageal fistula (BEF) secondary to esophageal diverticulum is a rare clinical condition, which is often misdiagnosed for a long time. The aim of our study is to summarize and clarify the advantages of MSCT in diagnosing BEF secondary to esophageal diverticulum. METHODS: We retrospectively analyzed patients clinically diagnosed with BEF from January 2005 to January 2022 at Jilin University First Hospital. Only those patients with BEF secondary to esophageal diverticulum and complete clinical data met our enrolled standard. All patients' clinicopathologic characteristics and MSCT features were systemically evaluated. RESULTS: 17 patients were eligible for our cohort study, including male 10 and female 7. The patient's mean age was 42.3 ± 12.5. The chronic cough occurred in all seventeen patients and bucking following oral fluid intake was documented in nine patients. MSCT distinctly suggested the fistulous tract between the bronchi and the esophagus in all patients. The mean diameter of the orifices in the wall of the esophagus was 4.40 ± 1.81 mm. The orifice in the midthoracic esophagus side was 15 cases and 2 cases at the lower thoracic esophagus. The involved bronchus included 13 cases at the right lower lobe bronchus, 1 at the right middle lobe bronchus and 3 at the left lower lobe bronchus. The contrast agent was observed in the pulmonary parenchyma in 10 of 13 patients who underwent esophagogram. No definite fistula was observed in 3 of 11 who underwent gastroscopy, while the intra-operative findings supported the existence of fistula. CONCLUSIONS: BEF secondary to esophageal diverticulum tends to occur between the midthoracic esophagus and the right lower lobe bronchus. Compared with esophagography and gastroscopy, MSCT shows more comprehensive information about the fistulous shape, size, course and lung involvement, which are helpful for establishing diagnosis and guiding subsequent treatment.

Inverted Placement of Endoscopic One-Way Endobronchial Valve Combined with Gelfoam in the Closure of Bronchopleural Fistula with Empyema in a Mechanically Ventilated Patient: A Case Report.

Bronchopleural fistula (BPF) with empyema caused by severe necrotizing pulmonary infection is a complicated clinical problem that is often associated with poor general condition so surgical interventions cannot be tolerated in most cases. Here, we present the successful management of multiple BPF with empyema in a mechanically ventilated patient with aspiration lung abscess. Occlusion utilizing Gelfoam followed by endobronchial valves (EBVs) implanted inverted via bronchoscope decreased the air leaking significantly and made intrapleural irrigation for empyema achievable and safe. This is the first report of a novel way of EBV placement and the combination use with other occlusive substances in BPF with empyema in a patient on mechanical ventilation. This method may be an option for refractory BPF cases with pleural infection.

Empiric flap coverage for the pneumonectomy stump: How protective is it? A single-institution cohort study.

OBJECTIVE: To evaluate the impact of empiric tissue flaps on bronchopleural fistula (BPF) rates after pneumonectomy. METHODS: Patients who underwent pneumonectomy between January 2001 and December 2019 were included. Primary end point was development of BPF. Secondary end points were impact of flap type on BPF rates, time to BPF development, and perioperative mortality. RESULTS: During the study period, 383 pneumonectomies were performed; 93 were extrapleural pneumonectomy. Most pneumonectomy cases had empiric flap coverage, with greater use in right-sided operations (right: 97%, 154/159; left: 80%, 179/224, P < .001). Empiric flaps harvested included intercostal, latissimus dorsi, serratus anterior, omentum, pectoralis major, pericardial fat/thymus, pericardium, and pleura. BPF occurred in 10.4% of the entire cohort but decreased to 6.6% when extrapleural pneumonectomy cases were excluded; 90% (36/40) of BPFs occurred on the right side (P < .001). Median time to develop BPF was 63 days, and 90-day mortality was greater in patients with BPF (12.5% BPF vs 7.4% non-BPF, P < .0001). Intercostal muscle had the lowest rate of BPF (4.5%), even in right-sided operations (8.7%). In contrast, larger muscle flaps such as latissimus dorsi (21%) and serratus anterior (33%) had greater rates of BPF, but the sample size was small in these cohorts. CONCLUSIONS: Empiric bronchial stump coverage should be performed in all right pneumonectomy cases due to greater risk of BPF. In our series, intercostal muscle flaps had low BPF rates, even in right-sided operations. Coverage of the left pneumonectomy stump is unnecessary due to low incidence of BPF in these cases.

[Risk Factors, Prevention, Diagnosis, and Treatment of Bronchopleural Fistula After Lung Resection].

Postoperative bronchopleural fistula (BPF) is a rare but severe and sometimes life-threatening complication that needs immediate and proper treatment. Thoracic surgeons should strictly manage the comorbidities such as diabetes mellitus for BPF prevention. Also, coverage of the bronchial stump with pericardial fat tissue will prevent BPF, or at least prevent the turning severe of BPF. However, when BPF occurs, we must promptly determine whether to perform conservative treatment or invasive treatment such as fenestration.

[Management of Postoperative Surgical Site Infection and Empyema After Thoracic Surgery].

Surgical site infections (SSI)[wound infection, empyema] after thoracic surgery can lead to severe complications. Targeted antibiotic treatment and drainage are the keys. For the treatment of postoperative empyema without bronchopleural fistula, chest tube thoracostomy and irrigation with normal saline is effective. For postoperative empyema with bronchopleural fistula, open window thoracotomy is a good treatment option. Since the condition of empyema is different in each patient, treatment should be individualized depending on the patient's condition.

Tuberculous Bronchopleural Fistula: A Rare and Life-Threatening Disease.

Tuberculous bronchopleural fistula (BPF) is a rare and potentially life-threatening complication of pulmonary tuberculosis, in which abnormal connections form between the bronchial tree and the pleural space. These abnormal connections allow air and secretions to pass from the lungs into the pleural space, causing a range of symptoms from benign cough to acute tension pneumothorax. The management of tuberculous BPF requires an individualized approach based on the patient's condition and response to treatment. Anti-tuberculosis therapy is essential for controlling the active tuberculosis infections. Intercostal drainage and suction are also commonly used to drain air and fluid from the pleural space, providing relief from the symptoms. For some patients, more invasive surgeries, such as decortication, thoracoplasty or pleuropneumonectomy are required to definitively close the fistula when medical management alone is insufficient. Herein, we describe a rare case of tuberculous BPF in a young adult female, who was treated with anti-tuberculosis medications and open thoracotomy.

[Staged reconstructive surgery for bronchopleural fistula]. / Etapnaya rekonstruktivno-vosstanovitel'naya khirurgiya pri bronkhoplevral'nom svishche.

Treatment of bronchopleural fistula after pneumonectomy is still an urgent problem for thoracic surgeons. Transsternal bronchial stump occlusion should be preferable if possible. However, this is not enough for curing in some cases. We present a patient with concomitant cancer and tuberculosis of lungs whose postoperative period was complicated by bronchial stump failure. Preoperative diagnostic data are presented. We describe the indications for surgeries and main surgical stages. Some interventions including reconstructive surgery using a muscle flap led to recovery. Latissimus dorsi muscle flap on thoracodorsal artery is the best option for reconstructive surgical treatment in patients with extensive chest wall defects and thoracostomy.

Vertical musculocutaneous trapezius flap for the closure of postpneumonectomy empyema.

OBJECTIVE: The aim of the study was to present our experience with the vertical musculocutaneous trapezius (VMCT) flap and highlight its utility in the thoracic wall reconstruction in patients with bronchopleural fistula (BPF). MATERIALS AND METHODS: We present a five case series of patients with long-standing cavities and BPF. The VMCT flap was used, and a direct pathway into the defect was made through a separate posterior thoracotomy shortening the distance between the flap and the defect. RESULTS: In 80% of the cases, the flap succeeded in solving the fistula and filling the defect, quality of life improved, and the need for oxygen decreased. CONCLUSIONS: Management of open window thoracostomy is challenging. Debridement, thoracoplasty, and flap coverage are the mainstream of their treatment, but these patients have scarce available muscle. The VMCT flap represents the major non-affected musculocutaneous unit in the thoracic area after lung surgery. Its dermal component offers a rigid matrix to form a seal over the bronchial stump. Its muscular component adds a good amount of vascularized tissue. No functional impairment has been described after its use.

OBJETIVO: Exponer nuestra experiencia con el colgajo vertical de trapecio y destacar su utilidad en la reconstrucción de la pared torácica en pacientes con fístulas broncopleurales. MATERIAL Y MÉTODOS: Presentamos una serie de cinco pacientes con cavidades y fístulas broncopleurales de larga evolución. Utilizamos el colgajo musculocutáneo vertical de Trapecio, con un redireccionamiento del mismo a través de una ventana costal que permite acortar la distancia entre el colgajo y el defecto. RESULTADOS: La fístula y el defecto fueron solucionados en el 80% de los casos. La calidad de vida mejoró y las necesidades de oxígeno disminuyeron. CONCLUSIONES: El manejo de las toracotomías es un reto. El desbridamiento, toracoplastia y cobertura con colgajo son los pilares de su tratamiento, pero estos pacientes tienen escasa disponibilidad muscular. El colgajo musculocutáneo vertical de Trapecio representa la mayor unidad intacta musculocutánea en el tórax tras cirugía pulmonar. Su componente dérmico ofrece una matriz rígida para sellar el muñón bronquial, su componente muscular añade una gran cantidad de tejido vascularizado. No se han descrito déficits funcionales tras su uso.

Complications of Transcatheter Arterial Chemoembolization for Hepatocellular Carcinoma: A Case Report of Bronchobiliary Fistula Development in a 68-Year-Old Man.

BACKGROUND Bronchobiliary fistulas (BBFs) are abnormal communications between the biliary tract and bronchial tree. Transcatheter arterial chemoembolization (TACE) is a widely employed treatment for advanced hepatocellular carcinoma (HCC). While TACE is generally considered safe, there have been reports of severe complications. This case report is about a 68-year-old man who developed a BBF 6 months after undergoing TACE for HCC. CASE REPORT A 68-year-old man was diagnosed with HCC and underwent TACE at a local medical department. Two months after TACE, he presented with a liver abscess, which was drained and catheterized. Subsequently, the patient was transferred to our hospital. Initial MRI revealed abscesses in the right hepatic lobe extending into the lung cavity. Intrahepatic catheter replacement was performed. Six months after TACE, the patient developed cough and yellow sputum. Subsequent MRI confirmed smaller lung and liver abscesses, along with a BBF. Endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous catheter replacement were conducted, closing the BBF with a covered stent. Despite drainage, antibiotics, and nutritional support, the patient's condition deteriorated. Transition to hospice care was initiated, and the patient died due to sepsis and multiple organ failure. CONCLUSIONS This case highlights the importance of obtaining a comprehensive patient history when a patient has bile in the sputum, and discusses the rare but previously reported BBF as a complication of TACE for HCC. The presence of bile collections in the lungs and liver can result in tissue necrosis, potentially leading to chronic infection, emphasizing the need for early diagnosis and management.

Who needs their descending thoracic aorta anyway? Extra-anatomic bypass for aorto-bronchial fistula after TEVAR.

BACKGROUND: Aortobronchial fistula after TEVAR remains a vexing clinical problem associated with high mortality. Although a combination of endovascular and open surgical strategies have been reported in managing this pathology, there is as yet no definitive treatment algorithm that can be used for all patients. We discuss our approach to an aortobronchial fistula associated with an overtly infected aortic endograft. CASE PRESENTATION: A 49-year-old female sustained a traumatic aortic transection 14 years prior, managed by an endovascular stent-graft. Due to persistent endoleak, she underwent open replacement of her descending thoracic aorta 4 years later. Ten years after her open aortic surgery, the patient presented with hemoptysis, and a pseudoaneurysm at her distal aortic suture line was identified on computed tomography, whereupon she underwent placement of an endograft. Eight weeks later, she presented with dyspnea, recurrent hemoptysis, malaise and fever, with clinical and radiographic evidence of an aortobronchial communication and an infected aortic stent-graft. The patient underwent management via a two-stage open surgical approach, constituting an extra-anatomic bypass from her ascending aorta to distal descending aorta and subsequent radical excision of her descending aorta with all associated infected prosthetic material and repair of the airway. CONCLUSION: Aortobronchial fistula after TEVAR represents a challenging complex clinical scenario. Extra-anatomic aortic bypass followed by radical debridement of all contaminated tissue may provide the best option for durable longer-term outcomes.

Coronary bronchial fistula - A rare incidental finding.

Coronary fistulas are unusual finding in coronary angiography (CAG) with coronary bronchial fistula (CBF) being a rarer one. Here, we represent a case of CBF which was diagnosed incidentally on CAG. These anomalous connections can be percutaneously treated.

Postoperative bronchopleural fistula after induction therapy with bevacizumab.

Bronchopleural fistulas are rare complications of bevacizumab treatment. Herein, we report a case of bronchopleural fistula after bevacizumab therapy. The patient was a 65-year-old man with lung cancer who underwent a right lower lobectomy with systemic lymph node dissection after induction chemotherapy with bevacizumab. Pathological examination revealed no residual tumor cells in the resected specimen. The patient presented with severe dyspnea on postoperative day 26. Bronchoscopy revealed a bronchopleural fistula in the membranous portion of the right intermediate bronchus; the bronchial stump remained intact. The bronchopleural fistula was repaired with muscle flaps, and bronchoscopy 9 months after surgery showed satisfactory healing of the fistula. The patient has been alive for 5 years without evidence of recurrence. Careful attention must be paid to postoperative management when bevacizumab is used for induction therapy.
