Right thoracotomy approach for treatment of left bronchopleural fistula after pneumonectomy for tubercolosis

Therapeutic strategy and efficacy evaluation of chronic empyema after total pneumonectomy: individualized analysis of six patients

BACKGROUND

Chronic empyema after total pneumonectomy is a potentially fatal complication.The aim of the study is to explore the treatment strategy and clinical efficacy of chronic empyema after pneumonectomy.

METHODS

A retrospective analysis of 6 patients with chronic empyema after pneumonectomy in our hospital. Utilizing a staged surgical model, the treatment approach involved rib debridement drainage, open-window thoracostomy (OWT), and the application of autologous tissue flaps, including free myocutaneous flap, pedicled muscle flap, and pedicled greater omentum, to effectively eliminate the abscess cavity.

RESULTS

All patients with empyema were successfully treated after surgery, with follow-up durations ranging from 3 to 29 months and an average of (10.50 ± 9.67) months. Re-examination using chest computed tomography (CT) or magnetic resonance imaging (MRI) revealed that the empyema residual cavity had either completely disappeared or had significantly reduced.

CONCLUSION

The treatment of chronic refractory empyema after total pneumonectomy by rib debridement drainage, OWT and autologous tissue flap transplantation has a high cure rate and satisfactory clinical effect.

Salvage treatment of acute respiratory failure after autogenous tissue flap transplantation for chronic empyema with chest wall sinus: a case report and literature review

BACKGROUND

Chronic empyema with chest wall sinus is a difficult and complex disease caused by multiple causative factors. It is difficult to control local infection due to its possible combination of bronchopleural fistula (BPF) and residual bone.The relevant literature emphasizes some risk factors for empyema progression after pneumonectomy, while the correlation between empyema and BPF after pneumonectomy increases mortality by infecting the remaining lungs. After pneumonectomy, the lung function of the contralateral side is particularly important.

CASE PRESENTATION

This paper reports a 62-year-old male patient who underwent right pneumonectomy for squamous cell carcinoma of the lung 12 years ago and began to develop empyema with anterior chest wall sinus 3 years ago. After admission, chest computed tomography (CT) showed right pleural effusion and formation of chest wall sinus. According to his clinical symptoms and imaging examination, he was diagnosed as chronic empyema with chest wall sinus.Due to the huge residual cavity of the patient,the clinical effect of using free vastus lateralis myocutaneous flap combined with pedicled pectoralis major muscle flap to fill the abscess cavity was satisfactory,but acute respiratory failure occurred due to left lung aspiration pneumonia after operation.

CONCLUSIONS

After a series of treatment measures such as tracheal cannula, tracheotomy, anti-infection, maintenance of circulatory stability, and rehabilitation training, the patient was ultimately rescued and cured. Postoperative follow-up showed that the muscle flaps survived and empyema was eliminated.

Autologous myocutaneous flap implantation for chronic refractory chest wall sinus with infection: a case report

BACKGROUND

Chest wall sinus with infection is a refractory disease caused by a variety of susceptible factors, and the treatment is still challenging. For clinically complex cases, although there are various surgical methods to choose from, it is still very difficult to achieve clinical cure, especially for patients with older age and many underlying diseases. Complete resection of chest wall sinus and application of repair and reconstruction technology may bring hope to refractory cases.

CASE PRESENTATION

Herein, we report a case of a 67 year-old woman who had undergone breast cancer surgery and a history of multiple cycles of radiotherapy and chemotherapy. One year ago, she had a fistula in the left chest wall with yellow purulent fluid. After admission to our hospital, chest computed tomography (CT) showed the formation of the left chest wall sinus, accompanied by high-density images of the left clavicle, part of the ribs and part of the sternu. According to the patient's symptoms, signs and imaging examination, we preliminarily diagnosed the patient as chest wall sinus with infection and chronic osteomyelitis. Therefore, in the first-stage operation, the patient underwent left chest wall sinus resection, left partial rib resection, left partial clavicular resection and left partial sternal resection, After surgery, the wound surface was changed with gauze dressing with sensitive antibiotic solution every day until the wound surface was clean and new granulation was formed. In the second-stage operation, the wound surface was appropriately expanded, and the pedicled latissimus dorsi myocutaneous flap was transferred to the chest wall defect. Finally, the skin paddle was sutured without tension to the normal skin around the chest, and two drainage tubes were placed. Anti-infection, anti-spasm, anti-coagulation and other treatments were given after operation, and the survival of myocutaneous flap, wound healing and sinus disappearance were observed.

CONCLUSION

The application of pedicled latissimus dorsi myocutaneous flap in the treatment of intractable chronic chest wall sinus is an effective method. It does not change the shape of the thorax. The clinical effect is satisfactory in the near and medium term, which is worthy of clinical promotion.

Prevention of bronchial fistulas after pneumonectomies for selected cavitary drug resistant lung tuberculosis

Background

The World Health Organization guidelines for management drug resistant tuberculosis include surgery as an additional method in selected cases. Pneumonectomies have higher risk of morbidity such as bronchial fistulas which may be prevented by bronchial stump covering. We compare two methods of bronchial stump reinforcement.

Methods and materials

A retrospective single center follow-up study was done in 52 patients who underwent pneumonectomy for drug resistant pulmonary tuberculosis. Between 2000 and 2017 we performed pneumonectomies with pericardial fat reinforcement of bronchial stump in group 1 (n = 42), and between 2017 and 2021 in group 2 with pedicled muscle flap reinforcement group 2 (n = 10).

Results

Bronchial fistulas occurred in 17/42 (41%) of patients group 1 and there was no fistula in group 2, and this was statistically different (Fisher's test p = 0.02). Post-operative complications were seen in 24/42 (57%) of the patients in Group 1, and 4/10 (40%) patients in Group 2 (Fischer's test p = 0.53). In group 1 positive bacteriology decreased from 74% to 24% just after surgery, and in group 2 it decreased from 90% to 10%, but this was not statistically different (Fisher's test p = 0.63). In group 1 no-one died the first month, but 8/42 (19%) died within a year; in group 2 one died within a month, and only this death (10%) within a year. This difference in case fatality was not statistically significant.

Conclusions

The use of pedicle muscle flap for bronchial stump coverage during the pneumonectomies for destructive drug resistant tuberculosis can prevent severe postoperative fistulas and improve postoperative life.

Preliminary experience of autologous free myocutaneous flap combined with free dermal graft in the treatment of refractory empyema with bronchopleural fistula

Objectives

To explore the effects of autologous free dermal graft combined with free myocutaneous flap on bronchopleural fistula (BPF) with empyema, we summarized and analyzed two cases.

Methods

Two patients with refractory empyema and BPF were treated with autologous free dermal graft combined with free myocutaneous flap. The treatment included debridement of empyema, rib resection drainage, repair of bronchopleural fistula, and free vastus lateralis myocutaneous flap transplantation to eliminate the empyema. After the free dermal graft was harvested from the healthy skin around the incision, it was inserted into the fistula and sutured with the surrounding pleural tissue. The keys to the operation lies in the anastomosis of the lateral circumflex femoral artery (LCFA), vein and nerve that supply the vastus lateralis muscle flap to the thoracodorsal vessels and nerves. After surgery, the empyema, air leakage, and the survival of the myocutaneous flap were observed.

Results

There was no disease recurrence after follow-up for seven and six months, respectively. Re-examination of the chest computed tomography (CT) or magnetic resonance imaging (MRI) indicated that the abscess cavity had disappeared. No necrosis of the myocutaneous flap was observed after surgery.

Conclusion

The application of autologous free dermal graft combined with free vastus lateralis myocutaneous flap transplantation is effective in the treatment of patients with bronchopleural fistula with refractory chronic empyema, and the clinical effect is satisfactory.
