A proposal for a postoperative protocol for the early diagnosis of bronchopleural fistula after lung resection surgery

Case report: Endobronchial closure of postoperative bronchopleural fistula with embolization coil: a sandwich-like approach

Background

Embolization Coil has been reported to effectively treat postoperative bronchopleural fistula (BPF). Little detailed information was available on computer tomography (CT) imaging features of postoperative BPF and treating procedures with pushable Embolization Coil.

Objective

We aimed to specify the imaging characteristics of postoperative BPFs and present our experience treating them with the pushable Embolization Coil.

Methods

Six consecutive patients (four males and two females aged 29-56 years) diagnosed with postoperative BPF receiving bronchoscopic treatment with the pushable Nester® Embolization Coil (Cook Medical, Bloomington, Indiana) were included in this single-center, retrospective study. Multiplanar reconstruction of multidetector CT scans was reviewed for the presence, location, size, and radiological complications of each BPF, including air collection, pneumothorax, bronchiectasis, and chest tube. Using standardized data abstraction forms, demographic traits and clinical outcomes were extracted from the medical files of these patients.

Results

The underlying diseases for lung resection surgery were pulmonary tuberculosis (n = 3), lung adenocarcinoma (n = 2), and pulmonary aspergillosis (n = 1). All patients had air or air-fluid collection with chest tubes on radiological findings. Multiplanar reconstruction identified the presence of postoperative BPF in all patients. Five fistulas were central, located proximal to the main or lobar bronchus, while one was peripheral, distant from the lobar bronchus. Fistula sizes ranged from 0.8 to 5.8 mm. Subsequent bronchoscopy and occlusion testing confirmed fistula openings in the bronchial stump: right main bronchus (n = 1), right upper lobe (n = 2), and left upper lobe (n = 3). The angioplasty catheter-based procedure allows precise fistula occlusion "like a sandwich" with the pushable Embolization Coil. Five patients with BPF sizes ranging from 0.8 to 1.5 mm were successfully treated with a pushable Embolization Coil, except for one with a BPF size of 5.8 mm. No adverse events or complications were observed throughout follow-up, ranging from 29 to 1,307 days.

Conclusion

The pushable Nester® Embolization Coil seems a minimally invasive, cost-effective, and relatively easy-to-perform bronchoscopic treatment for postoperative BPF with a size less than 2 mm. Further studies are required to ensure the use of pushable Embolization Coil in treating postoperative BPF.

[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.

An update on bronchopleural fistulae following cancer-related surgery

PURPOSE OF REVIEW

Bronchopleural fistulae (BPF) are rare complications in cancer-related surgery but impart significant morbidity and mortality. BPF may be difficult to identify, with a broad differential diagnosis at presentation, so it is critical to be aware of newer diagnostic and therapeutic approaches for this disease entity.

RECENT FINDINGS

Multiple novel diagnostic and therapeutic interventions are featured in this review. Reports of newer bronchoscopic techniques to localize BPF, as well as approaches for bronchoscopic management, like stent deployment, endobronchial valve placement, or alternative interventions when indicated are discussed, paying particular attention to factors that influence procedure selection.

SUMMARY

Management of BPF remains highly variable, but several novel approaches have shown improved identification and outcomes. Although a multidisciplinary approach is imperative, an understanding of these newer techniques is important to provide optimal care for patients.

The safety and acceptability of using telehealth for follow-up of patients following cancer surgery: A systematic review

INTRODUCTION

Although virtual consultations have played an increasing role in delivery of healthcare, the COVID-19 pandemic has hastened their adoption. Furthermore, virtual consultations are now being adopted in areas that were previously considered unsuitable, including post-operative visits for patients undergoing major surgical procedures, and surveillance following cancer operations. This review aims to examine the feasibility, safety, and patient satisfaction with virtual follow-up appointments after cancer operations.

METHODS

A systematic review was conducted along PRISMA guidelines. Studies where patients underwent surgical resection of a malignancy with at least one study arm describing virtual follow-ups were included. Studies were assessed for quality. Outcomes including adverse events, detection of recurrence and patient and provider satisfaction were assessed and compared for those undergoing virtual or in-person post-operative visits.

RESULTS

Eleven studies, with 3369 patients were included. Cancer types included were gynecological, colorectal, esophageal, lung, thyroid, breast, prostate and major HPB resections. Detection of recurrence and readmission rates were similar when comparing virtual consultations with in-person visits. Most studies showed high patient and healthcare provider satisfaction with virtual consultations following cancer resection. Concerns were raised about the integration of virtual consultations into workflows in fee-for-service settings, where reimbursement for virtual care may be an issue.

CONCLUSION

Virtual follow-up care can provide timely and safe consultations in surgical oncology. Virtual consultations are as safe as in-person visits for assessing complications and recurrence. Where appropriate, virtual consultations can safely be integrated into the post-operative care pathway for those undergoing resection of malignancy.

Cover always the bronchial stump! A flap could prevent catastrophic complications even in complete broncho-pleural fistula

Broncho-pleural fistula after pneumonectomy is a life-threatening condition with very high mortality rate, even if detected early. All symptomatic patients should be treated immediately. The diagnosis in the absence of symptoms poses the real difficulties of management. Early detection of asymptomatic post-pneumonectomy broncho-pleural fistula is usually fortuitous. The use of bronchoscopy allows direct and accurate evaluation of the stump. This reported case allows us to make several considerations on the treatment of fistulas, but above all to consider that the systematic bronchial stump coverage is fundamental not only for preventing fistulas, but also for limiting their enlargement and communication with the residual cavity, in order to prevent catastrophic complications.
