Endobronchial closure of a postpneumonectomy bronchopleural fistula

Pedicled gastric seromuscular patch for one-stage closure of a bronchopleural fistula: a case report

Background

One-stage closure and fenestration are the available surgical options for bronchopleural fistula (BPF). One-stage closure may be applicable in cases with favorable infection control. Closing the bronchopleural stump is difficult due to thick adhesion caused by inflammation and a high risk of pulmonary artery injury. We report the successful closure of a BPF using a gastric seromuscular patch with an omental pedicle flap.

Case presentation

A 73-year-old man underwent right lower lobectomy with ND2a-2 lymph node dissection for lung adenocarcinoma. He was admitted to a local hospital for pneumonia. Three days after admission, his thoracic cavity was drained and a BPF was suspected. During the primary operation, the latissimus dorsi muscle and anterior serratus muscle were dissected via posterolateral incision, and we decided to close the fistula using the gastric seromuscular layer and omental pedicle flap. The patient was discharged 20 days after surgery. After 2 years, he has not had cancer recurrence and currently leads an active life.

Conclusions

This method provided immediate airtight closure and luminal opening of the middle bronchus in our patient with a large BPF and appeared superior to using the omentum alone. This procedure is useful for one-stage closure and does not require fenestration in cases with favorable infection control.

Two Cases of Single-Stage Closure of a Bronchopleural Fistula Using Latissimus Dorsi Musculocutaneous Flaps after Lung Surgery

Two cases of successful primary closure of a bronchopleural fistula with favorable infection control using latissimus dorsi musculocutaneous flaps are reported. Case 1 was a 70-year-old man who underwent resection of the right lower pulmonary lobe due to right lung metastasis of sigmoid colon cancer. A bronchopleural fistula was found on day 28 after surgery. Infection was controlled by antibiotic administration and tube drainage. Closure of the bronchopleural stump, thoracoplasty and plombage of latissimus dorsi muscles were performed for single-stage closure without open treatment, based on a negative pleural effusion culture. Case 2 was a 64-year-old man who underwent right lower pulmonary lobe resection due to right lung cancer. A bronchopleural fistula was found on day 14 after surgery. In single-stage closure, thoracoplasty and plombage of latissimus dorsi muscles were performed due to infection control and a negative pleural effusion culture. Both cases had a good postoperative course.

Airway Complications After Pulmonary Resection

Airway complications following pulmonary resection remain a challenging problem. A high degree of clinical suspicion, contrasted CT imaging, and early reoperation are crucial in preserving viable lung parenchyma following the anatomic compromise of lobar torsion. Likewise, early recognition and expeditious drainage of the pleural space in the setting of bronchial dehiscence may help prevent the aspiration pneumonia and consequent respiratory failure that is the leading cause of death in this patient population; A variety of interventions to manage stump dehiscence are possible, but successful management still remains difficult and requires an individualized approach. Attention to technical details and avoidance of extensive dissection and tension should yield acceptably low rates of postoperative stenosis following bronchoplastic resection. These common themes of precise surgical technique, vigilance in the perioperative period, and classic sound judgment in addressing problems effectively and expeditiously remain pivotal in the minimization of sequelae from morbid airway complications.

Endoscopic closure of bronchopleural fistula after pneumonectomy by submucosal injection of polidocanol

We report two cases of a bronchopleural fistula with, and without, empyema treated by endoscopic submucosal injection of polidocanol (sclerotherapy) and application of cyanoacrylate. Case 1: A 60-year-old man underwent left pleuropneumonectomy for lung cancer. He developed bronchopleural fistula with empyema at 32 days after the operation. We performed sclerotherapy around the fistula. The air leakage stopped at 2 weeks after the sclerotherapy, and the fistula was closed. He was eventually cured of the empyema by pleural drainage. Case 2: A 61-year-old man underwent left pneumonectomy for lung cancer. He developed bronchopleural fistula without empyema at 50 days after the operation. We performed sclerotherapy and application of cyanoacrylate. After this therapy, the air leakage stopped immediately, and the bronchopleural fistula was closed. The sclerotherapy and application of cyanoacrylate are not only technically easy, but also very effective for treatment of bronchopleural fistula. Sclerotherapy and cyanoacrylate may be advocated as a first therapeutic step.

Percutaneous treatment of a pancreatic fistula after pancreaticoduodenectomy

Breakdown of the pancreaticojejunal anastomosis after a Whipple procedure is reported to occur in as many as 15% of cases. Intraoperative placement of a drain adjacent to the anastomosis is performed to allow the creation of a controlled pancreaticocutaneous fistula in the event of an anastomotic disruption. The authors present a case of successful percutaneous treatment of a disrupted pancreaticojejunal anastomosis. This was achieved with use of the resulting pancreaticocutaneous fistula for access to restore internal drainage, followed by fistula occlusion with use of gelatin pledgets.

Experience with thoracoscopic surgery for primary bronchial stump fistula after pneumonectomy

After a left pneumonectomy, thoracoscopic closure with fibrin glue was performed for a fistula on the bronchial stump and the postoperative state progressed favorably thereafter. In this paper, we report on this successful case.

CASE

A 61 year-old male, who underwent a left pneumonectomy on January 17, 1996 for pulmonary carcinoma (T 3 N 1M 0 stage III A). The bronchial stump was covered with anterior serratus muscle flap. On April 1 (the 76th postoperative day), after two courses of Carboplatin and Vindesine treatment, the patient suddenly developed a fistula on the bronchial stump. Bronchofiberscopic closure with fibrin glue was attempted, but failed to close the fistula. Thoracoscopic surgery was then performed on May 15 (the 45th day after the onset of the fistula). After the intrathoracic opening of the fistula was found with a contrast medium, fibrin glue was injected to fill up to the bronchial stump, and communication with the thoracic cavity was blocked. Owing to coverage with a myocutaneous flap, the patient's general postoperative state remained relatively stable. Thoracoscopic surgery is useful as a treatment for some cases of bronchial stump fistula after pneumonectomy.

Transsternal closure of bronchopleural fistula after pneumonectomy

BACKGROUND

Bronchopeural fistula after pneumonectomy, with associated empyema, has no standard therapy. The transsternal, transpericardial approach was used in all patients presenting with a large fistula.

METHODS

From 1974 through 1995, 55 patients underwent transsternal, transpericardial closure of a bronchopleural fistula. Mean age was 62.7 years (range, 33 to 78 years). Malignant disease had been the indication for pneumonectomy in 50 patients and benign lesions in 5 patients. The fistula was right-sided in 41 patients (74.5%), and the bronchial stump was less than 2 cm in 25 (45.5%). Treatment of the concomitant empyema was by closed drainage in 2 patients, by repeated needle aspiration in 17, and by open thoracostomy in 36 patients. Reamputation and closure of the stump was possible in 51 patients; in 4 a primary carinal resection was done.

RESULTS

Three patients died within 30 days after operation (5.4%, 70% confidence interval 2.4%-10.7%). Ten patients died late during hospitalization, total hospital mortality, 23.6% (70% confidence interval 17.3% to 31.0%). Recurrent fistula symptoms were caused by a large recurrency in 6 patients (all died), by a small one in 7 (one death due to pulmonary embolism). Mean duration of hospital stay was 56 days (range, 2 to 174 days). At follow-up of 42 patients, there were no recurrent fistulas. All patients with benign lesions are alive and well. Of 37 cancer patients, 29 died, more than half due to malignancy. Risk factors for death included recurrent fistula, short interval between pneumonectomy and onset of fistula, and closing technique. Risk factors for recurrent fistula were a short bronchial stump and the nonuse of an open thoracostomy.

CONCLUSIONS

Long-term results of transsternal closure are good, but hospital mortality is high. The present treatment of patients with large postpneumonectomy bronchopleural fistula includes early open thoracostomy, improvement of nutritional status, transsternal closure using resorbable sutures, and closure of the pleural space 3 weeks later.

Treatment strategies for bronchopleural fistula

Successful management of chronic postoperative bronchopleural fistula remains a challenge for thoracic surgeons. Forty-two patients (33 referred from other institutions) were treated for major postoperative bronchopleural fistula since 1978. Factors associated with bronchopleural fistula included right pneumonectomy (n = 23), left pneumonectomy (n = 8), long bronchial stump (n = 16), pneumonia (n = 13), radiation therapy (n = 12), stapled bronchial closure (n = 8), prolonged mechanical ventilation (n = 7), recurrent carcinoma (n = 6), and tuberculosis (n = 2). Patients had undergone an average of 3.3 surgical procedures to correct their bronchopleural fistulas during a mean interval of 24 months before our treatment. Bronchopleural fistulas were located in the right main bronchial stump (n = 23), left main bronchial stump (n = 8), right lobar bronchial stumps (n = 10), and tracheobronchial anastomosis (n = 1). Thirty-five patients were treated by suture closure of the bronchial stump, buttressed with vascularized pedicle flaps of omentum (n = 19), muscle (n = 13), or pleura (n = 2). In seven cases, direct suture closure was not possible, and omental (n = 6) or muscle (n = 1) flaps were sutured over the bronchopleural fistula. Suture closure without pedicle coverage was performed successfully in one case. Initial repair of the fistula was successful in 23 of 25 patients treated with omentum, in nine of 14 patients treated with muscle and in neither of two patients treated with pleural flaps. In nine patients with persistent or recurrent bronchopleural fistula after our initial repair, four underwent a second procedure (three successful) and five were managed with drainage only. The fistula was successfully closed in 11 of 12 patients who had received high-dose radiation therapy (nine with omentum). Overall, successful closure of bronchopleural fistula was achieved in 36 of 42 patients (86%). Four in-hospital deaths resulted from pneumonia and sepsis, two in patients with recurrent bronchopleural fistula after pleural flap closure. In 16 patients the empyema cavity was obliterated during definitive repair of the fistula. The cavity resolved with drainage in four others, nine had draining cavities at follow-up, and one was lost to follow-up. Ten patients required a total of 17 Clagett procedures and one had a delayed myoplasty. Direct surgical repair of chronic bronchopleural fistula may be achieved in most patients after adequate pleural drainage by suture closure and aggressive transposition of vascularized pedicle flaps. Omentum is particularly effective in buttressing the closure of bronchopleural fistulas.

Treatment of peripheral bronchopleural fistulas with endobronchial occlusion coils

Persistent peripheral bronchopleural fistulas can be difficult to manage. Endoscopic plugging of involved bronchi has been accomplished in a number of ways. We have devised a method of permanently blocking small peripheral airways using Gianturco vascular occlusion coils placed endobronchially by modified angiographic techniques. This procedure has been applied in 5 cases of complicated parenchymal air leaks. Complete or substantial partial control was achieved in all cases. There were no complications.
