Can total bronchopleural fistulas from complete stump dehiscence be endoscopically treated?

Endobronchial management of bronchopleural fistula using vascular plug device—a case report

Background

Bronchopleural fistula (BPF) is a sinus tract between the pleural space and the main stem, lobar, or segmental bronchus. The development of a bronchopleural fistula (BPF) is associated with high rates of morbidity and mortality. An interdisciplinary approach, early diagnosis, and timely management of these lesions are critical in the management of such lesions.

Case presentation

We describe a case of bronchopleural fistula in a 42-year-old female patient, occurring after a surgery for pulmonary hydatid, which was successfully managed using a minimally invasive method of closure using Amplatzer vascular plug (AVP).

To our knowledge, the use of an AVP for the management of a BPF following hydatid cyst marsupialization has rarely been described in the past.

Conclusion

AVP is a useful device in the management of bronchopleural fistulas, especially in patients failing a trial of conservative management and are high-risk candidates for surgeries.

[Surgical treatment of bronchopleural complications after lung resection and pleurectomy in patients with tuberculosis]

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 1^st 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.

Bronchoscopic device closure of postoperative bronchopleural fistulae: Novel devices and innovative techniques

Background

Bronchoscopic device closure plays a significant role in the nonsurgical management of bronchopleural fistulae (BPF). Herein, we describe our 10-year experience in the management of postoperative BPF using various device closure modalities. This is the largest series of bronchoscopic device closure of BPF being reported from India.

Materials and Methods

This was a retrospective analysis of data of patients who underwent bronchoscopic device closure with various techniques for the management of postoperative BPF. In total, 11 patients (six males and five females) with a mean age (±standard deviation) of 42.72 ± 14.40 years with BPFs were treated with various bronchoscopic interventions for BPF closure. We used various devices such as endobronchial coils, occluder devices, and covered tracheobronchial self-expandable stents for BPF closure depending on the size of air leaks. We describe the various devices used, technique, and outcome of bronchoscopic management of BPF.

Results

All our patients had developed BPFs postoperatively. Pulmonary tuberculosis was the most common etiology seen in nine of our patients. All the devices were placed using a fiberoptic bronchoscope, and all patients were followed up for a minimum duration of 6 months. We successfully localized and closed BPFs in nine (81.81%) of our patients.

Conclusions

Bronchoscopic device closure can be a successful strategy to manage postoperative BPF with minimal complications.

Closure of bronchopleural fistula by a septal occluder device: a case for close collaboration between heart and lung specialists

We present the case of a 66-year-old woman who underwent right inferior lobectomy for pulmonary carcinoma and developed persistent bronchopleural fistula (BPF) that was not amenable to surgical intervention (two surgical failures). The patient presented with a persistent cough and dyspnoea, which was treated with a hybrid procedure using fluoroscopy and bronchoscopy. A 7 mm Amplatzer septal occluder device (ASOD) was successfully inserted into the BPF. Two weeks after the procedure, a small fistula developed, which was treated by endoscopically guided biologic glue embolisation. At 2-month, 6-month and 12-month follow-up visits, clinical examinations and endoscopic imaging confirmed the complete occlusion of the BPF. Obvious migration of the ASOD was not apparent, and the patient has remained asymptomatic. The success of an endoscopic BPF closure with the use of hybrid techniques was achieved because of a collaborative effort by a multidisciplinary team.

Pulmonary inhalation-perfusion scintigraphy in the evaluation of bronchoscopic treatment of bronchopleural fistula

Objective

To evaluate the use of pulmonary inhalation-perfusion scintigraphy as an alternative method of investigation and follow-up in patients with bronchopleural fistula (BPF).

Materials and Methods

Nine patients with BPFs were treated through the off-label use of a transcatheter atrial septal defect occluder, placed endoscopically, and were followed with pulmonary inhalation-perfusion scintigraphy, involving inhalation, via a nebulizer, of 900-1300 MBq (25-35 mCi) of technetium-99m-labeled diethylenetriaminepentaacetic acid and single-photon emission computed tomography with a dual-head gamma camera.

Results

In two cases, there was a residual air leak that was not identified by bronchoscopy or the methylene blue test but was detected only by pulmonary inhalation-perfusion scintigraphy. Those results correlated with the evolution of the patients, both of whom showed late signs of air leak, which confirmed the scintigraphy findings. In the patients with complete resolution of symptoms and fistula closure seen on bronchoscopy, the scintigraphy was completely negative. In cases of failure to close the BPF, the scintigraphy confirmed the persistence of the air leak. In two patients, scintigraphy was the only method to show residual BPF, the fistula no longer being seen on bronchoscopy.

Conclusion

We found pulmonary inhalation-perfusion scintigraphy to be a useful tool for identifying a residual BPF, as well as being an alternative method of investigating BPFs and of monitoring the affected patients.
