Nil Intervention is at Times the Best Intervention: Benign emptying of pneumonectomy space.

A sudden drop of air-fluid level in the pneumonectomy space in the absence of a bronchopleural fistula and pleural infection is termed benign emptying of the pneumonectomy space (BEPS). We report a 28-year-old female patient who presented to a tertiary care referral centre, in Pondicherry, India in 2020 with multiple episodes of vomiting. Subsequent to a left-sided pneumonectomy due to tuberculosis, she was diagnosed with BEPS. Generally, patients with BEPS are clinically stable, afebrile with no fluid expectoration and have a normal white blood cell count. Bronchoscopy reveals an intact bronchial stump and pleural fluid cultures are often sterile. In terms of management, close monitoring and early detection of a bronchopleural fistula are the key points. BEPS should be a differential diagnosis in case of a drop in the air-fluid level of the post-pneumonectomy space. Awareness of this entity is crucial as it helps prevent unnecessary and morbid surgical interventions.

[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.

[Diagnosis and treatment of bronchopleural fistula after anatomical lung resections]. / Khirurgiya bronkhoplevral'nogo svishcha posle anatomicheskikh rezektsii legkikh.

OBJECTIVE: To assess the factors causing air leakage after anatomical lung resections and present a rational tactical approach for timely establishing the cause and level of bronchial fistula. MATERIAL AND METHODS: We analyzed 723 patients who underwent anatomical lung resection (pneumonectomy - 136 patients, anatomical lobectomy and segmentectomy - 513, video-assisted anatomical resection - 74 patients). RESULTS: In 506 (69.9%) cases, complete lung inflation after surgery was observed within 24-48 hours. Persistent air discharge for more than 3 days was observed in 141 (19.5%) patients. Prolonged air leakage for more than 7 postoperative days occurred in 50 (6.9%) patients. Air discharge for more than 10 days was considered abnormal and observed in 20 (2.8%) patients. Redo surgeries were performed in 49 patients with bronchopleural fistula at the level of segmental bronchi. Forty-two patients after primary thoracoscopy and 6 ones after primary thoracotomy underwent video-assisted resection of the lung with bronchopleural fistula after previous surgery. In 11 patients, re-thoracotomy was performed: middle lobectomy after previous right-sided upper lobectomy in 2 patients, lung resection after previous segmentectomy in 8 cases and atypical resection of bulla after previous right-sided lower lobectomy in 1 case. CONCLUSION: Surgical approach for persistent postoperative air leakage involves various surgical interventions. The best option is minimally invasive thoracoscopic procedure. This method is valuable to visualize bronchopleural fistula, eliminate air leakage, additionally reinforce pulmonary suture and perform targeted adequate drainage of the pleural cavity.

Hybrid Management of an Aortobronchial Fistula after Patch Aortoplasty for Aortic Coarctation in a Patient with SARS-CoV-2 Pneumonia: Case Report and Review of the Literature.

Aortobronchial fistula is a rare cause of repeated hemoptysis and a potentially fatal condition if left untreated. We present the case of a 40-year-old man with repeated hemoptysis, excessive cough, and epistaxis ongoing for several days after SARS-CoV-2 pneumonia diagnosis. The patient had a history of patch aortoplasty for aortic coarctation and aortic valve replacement with a mechanical valve for aortic insufficiency due to bicuspid aortic valve at the age of 24. Computed tomography scan performed at presentation revealed a severely dilated ascending aorta, a thoracic aorta pseudoaneurysm at the site of the former coarctation, an aortobronchial fistula suggested by the thickened left lower lobe apical segmental bronchus in contact with the pseudoaneurysm and signs of alveolar hemorrhage in the respective segment. The patient was treated with thoracic endovascular aneurysm repair (TEVAR) after prior hemi-aortic arch debranching and transposition of the left common carotid artery and subclavian artery through a closed-chest surgical approach. Our case report together with a systematic review of the literature highlight the importance of both considering an aortobronchial fistula in the differential diagnosis of hemoptysis in patients with prior history of thoracic aorta surgical intervention, regardless of associated pathology, and of taking into account endovascular and hybrid techniques as an alternative to open surgical repair, which carries a high risk of morbidity and mortality.

Tubercular Bronchoesophageal Fistula in an Adolescent Girl.

Bronchoesophageal fistula is a rare complication of Mycobacterium tuberculosis in children. An adolescent girl who was diagnosed of tubercular mediastinal lymphadenopathy with associated bronchoesophageal fistula at presentation, is reported here. This 16-y-old girl presented with high-grade fever, cough, decreased appetite, weight loss for 3 mo, and breathlessness for 10 d. Chest radiograph revealed hilar lymphadenopathy with bilateral pleural effusion. GA GeneXpert was positive for mycobacterium and rifampicin sensitivity. Despite antitubercular therapy cough persisted and there was a history of dry cough with food intake, especially more on liquids. Bronchoscopy and CECT chest confirmed bronchoesophageal fistula in the right main bronchus just below the carina. Child continued on tube feeding and antitubercular therapy. After completion of intensive phase, child improved with resolution of clinical symptoms and scarring of tract on repeat bronchoscopy. It is concluded that in children with combination of mediastinal lymphadenopathy and persistent cough following intake of food needs careful evaluation for trachea/bronchoesophageal fistula.

A systematic review of therapies for aortobronchial fistulae.

OBJECTIVE: The aim of the study was to summarize epidemiologic data about aortobronchial fistulae and compare outcomes (mortality, recurrence, reoperation) of open, staged, and endovascular repair of aortobronchial fistula. METHODS: A systematic literature review was conducted to identify eligible studies published between January 1999 and December 2019. The Cochrane Library, PubMed, and Scopus databases were used as search engines. Eligible studies included articles reporting postoperative outcomes (death/follow-up). Literature review revealed only case reports and small case series, and thus, only descriptive data with data heterogeneity were available. The corresponding authors were contacted to provide additional information or outcome updates (recurrence/reoperation/death). RESULTS: Overall, 214 patients (90 studies) underwent 271 procedures (including redo procedures and staged procedures). Most of the patients were treated by endovascular means (72.42%). Open surgical repair was performed in 21.96% and staged procedures in 5.6%. Aortobronchial fistulae were located most often in the descending thoracic aorta (zone 3 or 4) (64.6%) and in zone 2 (23.8%). Fourteen percent of aortobronchial fistulae developed after thoracic endovascular aneurysm repair. Recurrence or infection occurred in 20% (43) patients. Recurrences were, to some extent, associated with the presence of endoleak. Long-term antibiotic administration (>1 month) was instituted in 63 patients (29.4%), whereas 90 patients (42%) did not receive antibiotics beyond hospitalization. From the remaining 61 patients, 3 received lifelong antibiotics and for 58 patients data were not available. Considering outcomes, the mean follow-up was 25.1 months (0-188 months) and not significantly different among treatments. LIMITATIONS: Literature review has revealed only case reports and small case series, and thus, only descriptive data were available. Randomized controlled trials are not available due to the rarity of the disease, which significantly decreases the power of the present study. Also, this study reflects significant data heterogeneity due to the nature of the analyzed manuscripts and would benefit from large patient cohort studies that have not been conducted till today. CONCLUSIONS: Aortobronchial fistula is a complex disease. Endoleaks may be involved in the development and the recurrence process, and they should not be disregarded. Considering major outcomes (length of follow-up), the available treating strategies are equal, and thus, surgeons should feel confident to apply the treatment of their choice, keeping in mind their experience, patient's age, and clinical condition.

[Surgical treatment of bronchopleural complications after lung resection and pleurectomy in patients with tuberculosis]. / Khirurgicheskoe lechenie bronkhoplevral'nykh oslozhnenii posle rezektsii legkogo i plevrektomii u bol'nykh tuberkulezom.

OBJECTIVE: To increase an efficiency of surgical treatment of bronchopleural complications after lung resections and pleurectomies through the development of modern indications, treatment strategies, techniques and postoperative management. MATERIAL AND METHODS: We analyzed data in 252 patients with bronchopleural complications after lung resections and pleurectomies. The study included patients who underwent treatment at the Central Research Institute of Tuberculosis for the period 2004-2010, Clinical Hospital of Phthisiopulmonology of the Sechenov First Moscow State Medical University for the period 2011-2017 and Thoracic Center of the Republic of Ingushetia for the period 2015-2019. The study included patients with postoperative pleural empyema divided into two groups: group I - 138 patients with empyema and bronchial fistula; group II - 114 patients with empyema and no bronchial fistula. In the 1st group, 1 patient had bronchial and esophageal fistulas. RESULTS: At discharge, empyema and bronchial fistula were eliminated in 245 (97.2%) patients of both groups. Overall in-hospital mortality was 1.6% (4 cases). Two (1.4%) patients died within 30 days in group I and 1 (0.9%) patient died in group II. Within 90 days after surgery, another patient died from acute cerebrovascular accident in group I. In long-term period, overall effectiveness of treatment of bronchopleural complications was 97.2% (208 out of 214 cases). CONCLUSION: The original surgical approach for bronchopleural complications considers timing of postoperative empyema, its spread and duration. This method together with minimally invasive interventions reduces mortality and ensures stable recovery after bronchopleural complications in 97.2% of patients.

Bronchobiliary fistula: a clinical and surgical challenge. Presentation of a pediatric case. / Fístula biliobronquial, un desafio clínico-quirúrgico. Presentación de un caso pediátrico.

INTRODUCTION: Congenital bronchobiliary fistula is an extremely rare malformation with high morbidity and mortality rates. Up to 2016, 36 cases had been reported worldwide. CLINICAL CASE: 11-year-old male patient with history of chronic lung disease and respiratory insufficiency, bile ptyalism and 66-80% arterial saturation, jaundice, asymmetric thorax, finger clubbing, and disseminated crackling rales. He was diagnosed through fibrobronchoscopy and CT-scan. After fistula closure and right pneumonectomy, recurrence occurred due to bile duct hypoplasia as evidenced by endoscopic retrograde cholangiopancreatography. Left lateral hepatic segmentectomy and fistula closure from the abdomen were carried out. Bronchopleural fistula persisted following intensive nutritional and antibiotic treatment. It was surgically closed using a bovine pericardial patch. Six months later, the patient had no symptoms. DISCUSSION: Given how extremely rare this malformation is, cross-disciplinary treatment and a high grade of suspicion are needed. The presence of bile duct hypoplasia is to be considered, since it requires a thoracoabdominal approach.

INTRODUCCION: La fístula biliobronquial congénita es una muy rara malformación con alta morbimortalidad. Hasta 2016 se habían reportado 36 casos en el mundo. CASO CLINICO: Paciente masculino de 11 años de edad, antecedentes de neumopatía crónica más insuficiencia respiratoria, bilioptisis, saturación arterial entre 66-80%, ictericia, tórax asimétrico, dedos hipocráticos, estertores crepitantes diseminados. Diagnóstico positivo por fibrobroncoscopia y tomografia axial computarizada. Tras cierre de fístula y neumonectomía derecha, se produjo recidiva por hipoplasia de la vía biliar comprobada con colangiopancreatografía retrógrada endoscópica. Se realizó segmentectomía hepática lateral izquierda y cierre de fístula desde el abdomen. Mantuvo fístula broncopleural persistente, luego de tratamiento nutricional y antibiótico intensivo, se cerró quirúrgicamente con parche de pericardio bovino. Asintomático tras 6 meses. COMENTARIOS: La muy baja frecuencia de esta malformación obliga a un alto índice de sospecha y un tratamiento multidisciplinario. Es importante considerar la presencia de hipoplasia de la vía biliar pues obliga a un abordaje toracoabdominal.

[Esophagotracheal and esophagobronchial fistulas]. / Ösophagotracheobronchiale Fisteln.

Esophagobronchial and esophagotracheal fistulas are rare but complex diseases with a heterogeneous spectrum of underlying etiologies. Common causes are locally advanced tumors of the esophagus and larynx, traumatic perforation from the esophageal or tracheal side as well as postoperative fistulas. The management of esophagotracheal and esophagobronchial fistulas always involves different health care providers and in most cases patients require a multidisciplinary treatment on the intensive care unit. The therapeutic concept primarily depends on the underlying cause, localization and size of the fistula but decision making is also influenced by the severity of the course of sepsis and the extent of the respiratory dysfunction. Endoscopic management with esophageal and/or tracheobronchial stenting is the most common treatment. Surgical reconstructive procedures are predominantly reserved for patients with a treatment refractory fistula or a septic multiple organ failure. The prognosis is particularly influenced by the underlying disease.

Bronchoscopic Treatment of Tracheobronchial Fistula With Autologous Platelet-Rich Plasma.

Tracheobronchial fistula (TBF) is a challenging management condition. Several bronchoscopic procedures have been tried for fistula closure. However, none has been found to be superior to the others. We herein describe a novel technique involving the submucosal injection of autologous platelet-rich plasma (auto-PRP) around the fistula to close the TBF. After auto-PRP treatment, all 3 TBF patients have successfully healed. No treatment-related complications and fistula-related symptoms were detected. Thus, this application of auto-PRP for fistula closure is a feasible and cost-effective strategy and could be recommended as a valuable therapeutic alternative for repairing postoperative TBF.

Salvage Lobectomy to Treat Necrotizing SARS-CoV-2 Pneumonia Complicated by a Bronchopleural Fistula.

We report a case of necrotizing severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia complicated by a bronchopleural fistula and treated by decortication and salvage lobectomy. Owing to the unknown characteristics of the underlying SARS-CoV-2 infection, treatment of the abscess and bronchopleural fistula was delayed. This may have resulted in further deterioration of the patient, with ensuing multiple organ dysfunction. Complications of SARS-CoV-2 pneumonia, such as a bacterial abscess and a bronchopleural fistula, should be treated as if the patient were not infected with SARS-CoV-2.

Getting the wind knocked out of him - Report of a broncho-cutaneous fistula caused by staphylococcal pneumonia, and review of literature.

A broncho-cutaneous fistula (BCF) refers to the formation of an abnormal fistulous connection between the tracheobronchial tree and the cutaneous surface of skin. A rare occurrence in and of itself, the disease entity may have varied etiologies, and may or may not be associated with a broncho-pleural fistula. We describe a case of a young patient who developed a BCF as a complication of a necrotizing pneumonic process, and his subsequent clinical course. In so doing, we review the clinical features of this peculiar disease entity, analyzing the available medical literature similarities in etiology and variations in management strategies described in the literature thus far.

Rare broncho-pulmonary arterial fistula in a healthy 9-year-old girl.

A 9-year-old previously well girl presented with multiple episodes of large volume haemoptysis and right sided consolidation. She continued to have haemoptysis despite intravenous antibiotics. CT chest suggested a right mainstem endobronchial lesion; this was not seen on bronchoscopy where an extensive blood clot was removed. Distal flexible bronchoscopy could not identify the source of bleeding. CT angiogram revealed a broncho-pulmonary arterial fistula, a rare cause of haemoptysis in children. Endovascular embolisation resulted in short-term symptom resolution; however, haemoptysis recurred months later, leading to re-embolisation. This case highlights a stepwise approach to the workup of large volume haemoptysis.

Successful coil embolisation for an arterio-bronchial fistula in a child presenting catastrophic haemoptysis.

We report the case of a 2-year-old girl who developed catastrophic haemoptysis due to an arterio-bronchial fistula after transcatheter balloon dilatation for a narrowing aortopulmonary shunt. We embolised the fistula while haemoptysis was controlled with the left bronchial block ventilation and haemostatic balloon occlusion of the left subclavian artery. An arterio-bronchial fistula is an extremely rare complication for balloon dilatation of an aortopulmonary shunt.

Death due to a bronchus-pulmonary artery fistula developed 19 years after radiotherapy: A forensic autopsy case report.

Radiotherapy, one of the standard therapies for lung cancer management, may cause severe late complications. In this case report, we describe the forensic autopsy report of a middle-aged man who died from a massive hemoptysis due to a bronchus-pulmonary artery fistula that developed 19 years after radiotherapy. The man, in his 50 s, suddenly developed hemoptysis at home and collapsed. He was in complete remission with no signs of recurrence. Autopsy revealed massive hemorrhage from the bronchus-pulmonary artery fistula, where radiotherapy had been focused. Histopathological findings showed chondronecrosis of the bronchus, disruption of elastic fibers of the pulmonary artery, and marked thickening of the intima of the small arteries around the fistula, which were compatible with radiation reaction. Neither cancer recurrence nor infection was evident. This case suggests that a late complication of radiotherapy should be considered in the differential diagnosis of a patient who was previously received radiotherapy and presents with massive hemoptysis. In such cases, a detailed history on previous therapies and careful examination of the origin of hemorrhage are necessary to determine the cause of death.

Development of Bronchopleural Fistula Complicated by Empyema Fifteen Years After Right Lower Lobe Lobectomy: A Case Report.

BACKGROUND Bronchopleural fistula formation is a rare complication of lobectomy surgery, with a frequency reported ranging from 0.5% to 1%. A post-lobectomy bronchopleural fistula usually presents within 14 days of surgery. To our knowledge, it is extremely rare for a bronchopleural fistula to develop many years after an operation. CASE REPORT We present the case of a 55-year-old male smoker with history of a right lower lobe lobectomy 15 years prior who presented to the Emergency Department with complaints of worsening back pain, shortness of breath, and cough productive of sputum. He was found to have a right bronchopleural fistula with right-sided empyema. He was taken to the operating room a few days after initial admission for right thoracoscopic chest exploration, right chest debridement, right chest wall resection, and window procedure with creation of pleurocutaneous fistula. Ultimately, he required a right completion pneumonectomy and buttress of bronchial stump with transdiaphragmatic omental flap. CONCLUSIONS We diagnosed a rare case of post-lobectomy bronchopleural fistula complicated by an empyema that demonstrates bronchopleural fistulas can appear 15 years postoperatively and present with subacute clinical signs and symptoms.
