Surgical Management of Late Postpneumonectomy Bronchopleural Fistula: The Transsternal, Transpericardial Route

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.

Transsternal Approach for Broncho-Pleural Fistula Closure After Right Pneumonectomy

Broncho-pleural fistula (BPF) is an abnormal communication between the bronchial lumen and the pleural space that typically occurs postoperatively. Surgical intervention is typically needed to patch the fistula; however, current literature lacks a gold standard for which treatment to use. With a high mortality rate, there is a clear urgency for quick and successful intervention. This case examines a 59-year-old patient presenting with a BPF 14 years after incidental pneumonectomy during upper lobectomy for invasive aspergillus. A fistula was appreciated during bronchoscopy with contrast injection. The fistula was closed via the transsternal approach through median sternotomy and pericardiotomy. This case report aims to provide a viable option to successfully repair a BPF via the transsternal approach.

[Cogitum in children's neurology and psychiatry (experience in the practical use)]

The authors review current data on the role of the synthetic aspartic acid analogue N-acetyaspartate (NAA) in various biochemical metabolic reactions in the CNS. Its importance as a biomarker for neuropsychiatric disorders identified using magnetic resonance spectroscopy (MRS) is noted. The authors present their own results of the use of cogitum, a synthetic analogue of NAA, in children with the effects of traumatic brain injury, mental retardation, hyperactivity disorder and in the complex therapy of schizotypal disorder. Effects of cogitum on cognitive deficit, asthenia are evaluated. The neurotrophic effect of the drug, which specifically affects cognitive and asthenic disorders in these diseases, is shown.

背景与目的

支气管胸膜瘘（bronchopleural fistula, BPF）是胸外科肺切除术后常见并发症，临床治疗复杂且效果不佳。对于肺切除术后支气管胸膜瘘的处理一直困扰着胸外科医生。总结我院胸外科中心予大网膜胸腔移植覆盖支气管残端治疗肺切除术后出现BPF的临床资料，分析出现BPF的原因，总结外科治疗的方法，探讨其可行性、安全性及小样本的成功率。

方法

2016年8月-2018年2月，我中心对接受肺切除术后发生BPF的患者6例，进行再次开胸补救性手术、大网膜胸腔内移植覆盖支气管残端治疗。2例首次手术行肺叶切除（分别为右肺上叶及中下叶切除，再次手术均行患侧残肺切除，直线切割器缝合主支气管），4例首次手术行全肺切除（左右各2例）。术中予4-0微荞线修补主支气管残端后于心膈角处打开膈肌将大网膜移植入胸腔内后覆盖支气管残端。S术后予生理盐水浸泡胸腔。回顾分析上述6例患者的临床资料，总结该术式治疗肺切除术后BPF的临床效果。

结果

6例均为男性，中位年龄66岁（61岁-73岁）；术后发生BPF中位时间为术后25天（10天-45天）。再次手术中位时间为110 min（80 min-150 min），术中中位出血量450 mL（200 mL-1, 000 mL），再次手术后住院时间中位天数14天（12天-17天）。6例患者术后均恢复良好痊愈出院，支气管残端闭合良好，成功率为100%。随访1个月-18个月各病例均未再出现BPF相关并发症。

结论

肺切除术后发生BPF，如患者全身情况尚可耐受手术，应尽早行补救性手术，带蒂大网膜瓣容易获取，胸腔内移植覆盖支气管残端疗效确切可靠，值得临床推广应用。
