Andrews thoracoplasty as a treatment of post-pneumonectomy empyema: experience in 23 cases

BACKGROUND

Andrew's thoracopleuroplasty has been described for treating tuberculous empyemas with bronchopleural fistulas. We report on its utilization for treating postpneumonectomy empyemas.

METHODS

During a 25 year period, 23 patients underwent thoracopleuroplasty for treating postpneumonectomy empyemas, after a period of drainage-irrigation of the cavity. Seven patients presented with persistent bronchial fistula at operation. After resection of the costal arches surrounding the infected cavity, the cavity was cleaned, and the external parietal plane was sutured to the mediastinal plane. Only drainage of the subscapular space was left in place.

RESULTS

Postoperative mortality was 4.3%. Postoperative recovery was simple in 17 cases, whereas a superficial abscess was evacuated in 3 cases. The procedure failed in 3 cases, which were treated by open thoracostomy (2), and by reenlargment of the thoracopleuroplasty (1). The sequelae were mainly a diminution of the shoulder mobility, especially when the first rib was resected.

CONCLUSIONS

Thoracopleuroplasty may safely treat postpneumonectomy empyemas, even those with bronchial fistulas. Most patients are definitively and rapidly cured with limited sequelae.

Unusual origin and fistulization of an aortic pseudoaneurysm: "off-pump" surgical repair

Aortic pseudoaneurysm is an unusual complication of cardiac operations. The origin depends on the site of arterial wall disruption. Rupture into the right side of the bronchial tree is an exceedingly rare evolution. Repair is commonly performed using cardiopulmonary bypass. In our report a male patient underwent two procedures for aortic dissection, and 6 months after the second operation massive hemoptysis appeared abruptly. A false aneurysm rose from a graft-to-graft anastomotic site and ruptured into a segmental bronchus of the right upper lobe. Repair was performed without cardiopulmonary bypass.

[Omentopexy as the operation of choice in treating recurrent postpneumonectomy pleural empyema with a bronchopleural fistula]

In 6 patients with recurrent postpneumonectomy pleural empyema and bronchopleural fistula the transdiaphragmatic omentopexy for the pleural cavity remnant was performed. In 5 patients the complete remission was noted, one patient died, the death's cause was not related directly with the operation performed. The control group of 20 patients had similar pathological findings and to them conventional methods of treatment were applied. In 10 patients the remission was achieved, in 5--the bronchial fistula recurrence was noted, 5 patients died. Thus, the total clinical efficacy was 83.3 and 50% accordingly.

Videothoracoscopic debridement of the postpneumonectomy space in empyema

OBJECTIVE

Simple irrigation has proven to be an efficient method to treat postpneumonectomy empyema provided that bronchopleural fistula is not present or successfully closed. However, with this treatment modality, infected material inside the thoracic cavity is not removed and this can be a potential source of empyema recurrence if the patient's immune system is compromised. The removal of the infected material should result in a lower recurrence rate.

METHODS

As soon as diagnosis of postpneumonectomy empyema was established, a chest tube drainage was inserted. A concomitant bronchopleural fistula was evaluated bronchoscopically. If the fistula was smaller than 3 mm, bronchoscopic sealing with fibrin glue (Tissucol, Immuno, Vienna) was initiated. Fistulas closed surgically were excluded from this analysis. The thoracic cavity was cleared of infected material by videothoracoscopy and bacteriological samples were taken. Immediately after operation antibiotic irrigation according to culture sensitivity was started via a single chest tube drainage twice a day. After instillation of antibiotics the drain was kept clamped for 3 h. Culture samples were obtained twice a week. Empyema was considered eradicated, if three subsequent cultures showed no bacterial growth. After drain removal the patients were kept in hospital for another week and observed for clinical signs of infection; WBC and CRP were controlled.

RESULTS

Nine patients (five men, four women) between 55 and 72 years (mean 61, SD 6), all initially operated on for malignancy, were successfully treated with this regimen. In three cases a concomitant bronchopleural fistula was successfully closed before videothoracoscopy. The interval between primary operation and empyema was between 7 and 436 days (mean 93, SD 141). There was no postoperative mortality and no procedure related morbidity. Operating time ranged from 45 to 165 min (mean 92.7, SD 36.6), the suction volume (consisting of blood, debris and pus) was 300 to 1000 ml (mean 880, SD 600). Duration of thoracic drainage was 12-38 days (mean 22, SD 9), duration of hospital stay after videothoracoscopy 21-46 days (mean 29, SD 9). During the follow-up period of 204-1163 days (mean 645, SD 407) no recurrence of tumour or empyema was observed.

CONCLUSIONS

Videothoracoscopic debridement of the postpneumonectomy space with postoperative antibiotic irrigation of the pleural space is an efficient method to treat postpneumonectomy empyema, provided that a concomitant bronchopleural fistula can be closed successfully. No early empyema or fistula recurrence were observed. However, late recurrence may occur many years after operation, therefore close follow-up is indicated.

Intrathoracic application of the reverse latissimus dorsi muscle flap

The use of the reverse latissimus dorsi muscle flap based on its paraspinous perforators for posterior trunk wound coverage has been described previously. However, few studies have reported its intrathoracic application. In this study the authors present their experience in treating 3 patients with various intrathoracic defects using the reverse latissimus dorsi muscle flap. There were 1 male and 2 female patients who ranged in age from 4 to 74 years (mean, 49 years). The etiology included an infected aortic graft, a bronchopleural fistula, and a recurrent congenital diaphragmatic hernia. Follow-up ranged from 2 to 24 months. Successful outcomes were achieved in all 3 patients, and there was no recurrence or wound complication identified. Their results demonstrate the versatility and reliability of the reverse latissimus dorsi muscle flap in treating low posterior intrathoracic defects.

Bronchoperitoneal fistula secondary to chronic Klebsiella pneumoniae subphrenic abscess

We treated a case of bronchoperitoneal fistula secondary to a Klebsiella pneumoniae subphrenic abscess. This fistulous communication and the surgical procedure used to treat it are described.

Congenital broncho-oesophageal fistula associated with bronchiectasis in adults. Report of two cases and review of the literature

Congenital broncho-oesophageal fistula is a rare entity in adult patients. This anomaly may cause various symptoms such as respiratory infections, coughing bouts when eating or drinking and even haemoptysis. Even rarer than its occurrence with the above-mentioned symptoms is its presentation with bronchiectasis. A congenital broncho-oesophageal fistula presenting with bronchiectasis in a 28-year-old male and 36-year-old female are described. In reported cases, symptoms of chronic recurrent pulmonary suppuration were initially attributed to alternative aetiologies. In both cases, with such an unusual presentation, the observation of the fistulous tract was coincidental. Surgical division of the fistula associated with lobectomy resulted in complete resolution of symptoms.

Videothoracoscopy and muscle flaps in the treatment of bronchial stump fistula

The aim of the paper is to report our surgical technique applied for treatment of broncho-pleural fistula (BPF) as well as the results of the treatment. From 1992 to 1998 we performed 127 pneumonectomies for lung cancer. In 5 cases (3.9%) bronchial stump insufficiency developed postoperatively. Three patients were treated by means of videothoracoscopy (the Multifire Endo Hernia Stapler was used to clipped the fistula). Rethoracotomy with myoplasty was performed four times in 3 patients. In one patient both the methods were employed. In 2 out of 3 cases videothoracoscopic treatment was successful and the patients were discharged without signs of BPF and pleural empyema. In one case the recurrence of the fistula occurred and the stump of the bronchus was successfully covered with the pectoral musce flap 3 days later. In two cases after rethoracotomy and myoplasty (one of them was reoperated twice) the recurrence of BPF occurred and both the patients died due to cardiopulmonary failure. Despite the limited experience, we think videothoracoscopy is worth considering as a tool for treatment of BPF.

Closure of bronchopleural fistula after pneumonectomy with a pedicled intercostal muscle flap

OBJECTIVES

The value of the pedicled intercostal muscle flap for the closure of postpneumonectomy bronchopleural fistulas was studied retrospectively.

METHODS

Bronchopleural fistula was suspected in case of fever, cough, putrid or haemorrhagic expectoration, in combination with a rise of WBC and CRP. Fistula diagnosis was established bronchoscopically. Two patients underwent an initial trial of bronchoscopic sealing, the rest were reoperated immediately after fistula diagnosis. Immediately after operation antibiotic irrigation according to culture sensitivity was started via a single chest tube drainage twice a day. After instillation of antibiotics the drain was kept clamped for 3 h. Culture samples were obtained twice a week. Empyema was considered eradicated, if three subsequent cultures showed no bacterial growth. After drain removal the patients were kept in hospital for another week and observed for clinical signs of infection, WBC and CRP were controlled. Age, side, sex, histology, TNM-stage, duration of hospital stay after fistula diagnosis (days), duration of treatment (defined as the duration of chest tube drainage in days after operation), total hospital stay (including the initial hospital stay for primary resection and the hospital stay for fistula treatment in case of readmission), fistula size (mm), interval (days) between primary operation and fistula formation, and bacteriology were recorded.

RESULTS

Eight patients (seven male) were treated. Age ranged from 46 to 70 years (mean 57.86). Six fistulas were located on the right side. All patients had non small cell lung cancer. Interval ranged from 2 to 72 days (mean 26.9 days). Fistula size ranged from 1 to 7 mm (mean 3.43). Seven fistulas were successfully closed. Duration of treatment lasted from 15 to 28 days in those patients treated successfully (mean 17). Hospital stay ranged from 15 to 31 days (mean 24.4). In one patient the flap became necrotic, he was successfully treated with total thoracoplasty. One patient died on the 38th day after rethoracotomy due to aspiration pneumonia. At postmortem examination the bronchial stump was closed.

CONCLUSION

The use of the pedicled intercostal muscular flap is an efficient method for the closure of bronchopleural fistula after pneumonectomy.

Incidence, risk factors and management of bronchopleural fistulae after pneumonectomy

Postpneumonectomy bronchopleural fistula (BPF) remains a serious and often life-threatening complication. Over a seven-year period, seven cases of BPF occurred in a series of 100 consecutive pneumonectomies performed for lung carcinoma by the same surgical team. The incidence increased from 3% (1/33) prior to 1993 to 9% (6/67) thereafter. The presence of tumour within the main stem bronchus and the need for postoperative mechanical ventilation correlated significantly with the occurrence of BPF. However, it is likely that other risk factors, such as the introduction of systematic mediastinal lymph nodes dissection since 1992 and bronchial stapling since 1993, were involved. In four patients, closure of BPF was achieved by transposition of pedicled latissimus dorsi (LD) muscle flap and closed-chest irrigaiton of the pleural cavity. Patients were discharged after a median stay of 19 d; fistula recurred in one case and was successfully treated with an omental flap. No complications related to the LD division were observed. In conclusion, mediastinal lymph node dissection may increase the risk of post-pneumonectomy BPF. Systematic bronchial stapling should be used cautiously, especially if the tumour is present within the main stem bronchus. Treatment with predicted LD muscle flap or omental flap associated with closed-chest irrigation proved to be simple, time-saving and efficient.

Management of aortobronchial fistula with an aortic stent-graft

Aortobronchial fistula presenting as massive hemoptysis is a rapidly fatal process that is extremely difficult to manage. We report a case in which endovascular occlusion of a fistula between a thoracic aortic pseudoaneurysm and lung was successfully managed by placement of an aortic endovascular stent-graft. Stent-grafting is a promising technique in managing complications of thoracic aneurysms and grafts.

Impact of different coverage techniques on incidence of postpneumonectomy stump fistula

OBJECTIVE

Postpneumonectomy bronchial stump fistula (PBSF) is a serious complication with a reported incidence between 0 and 12%. The aim of this retrospective study was to investigate the effectiveness of different coverage techniques of the bronchial stump applied in a consecutive series of pneumonectomies in avoiding this particular problem.

METHODS

Between 1/87 and 10/97, 129 patients (90 male, 39 female, mean age 57.8 years, range: 15-78 years) underwent pneumonectomy by one surgeon (W.K.). In 14 patients, additional resection procedures were performed (aorta n = 6, vena cava n = 5, thoracic wall n = 3). In all patients with malignancies (n = 123), mediastinal lymphadenectomy was routinely added to the procedure. Bronchial stump closure was performed by means of stapling devices in all patients. Coverage of the bronchial stump was performed with a generous pedicled pericardial flap and concomitant reconstruction of the pericardium with Vicryl mesh (n = 50), with a portion of the posterior pericardium (n = 16), with the azygos vein (n = 12), with surrounding mediastinal tissue (n = 25), with pleura (n = 16), or with intercostal muscle flap (n = 3); no coverage at all was performed in seven patients. In all patients with high risk for development of PBSF, i.e. patients who received any form of neoadjuvant therapy or had extended resections, the pericardial flap technique was used.

RESULTS

Perioperative mortality was 5.4% (n = 7) and five patients (3.9%) experienced significant perioperative complications, with one of them directly related to the method of bronchial stump coverage (cardiac tamponade due to the use of a too small Vicryl mesh for reconstruction of the pericardium). Follow-up was 96.1% complete (five patients were lost to follow-up). Fourty-seven patients (36.4%) died late after operation (mean 19+/-13 months, median 17 months), mainly due to recurrence of their underlying malignant disease. PBSF occurred in one patient only (0.8%), 2 weeks after operation (coverage with pleura). No PBSF was seen in the long term follow-up period.

CONCLUSION

Coverage of the bronchial stump contributes to a low incidence of PBSF. In view of the fact, that this serious complication was completely avoided in the pericardial flap group (used in patients with expected higher risk for PBSF), this particular technique seems to offer the best results.

Developing bronchial fistulas as a late complication of extraperiosteal plombage

A 65-year-old male, who underwent extraperiosteal plombage for pulmonary tuberculosis 46 years ago, was referred to our hospital due to relapsing hemosputa and pneumonia. A chest computed tomography scan revealed a bronchial fistula and a fluid collection in one Lucite ball. On May 20, 1996, a right-anterior thoracotomy was performed in a supine position. Five Lucite balls were removed, and the empyema space was tightly filled with an omental pedicle flap. Although the bronchial fistulas were not sutured directly, the air leakage from the drainage tube ceased 12 days later. Two years postoperatively the patient has remained well. Our simple approach of combining an anterior thoracotomy and replacement of an empyema space with an omental pedicle flap in the same posture, without closing bronchial fistulas, would be an easy procedure, and therefore exploitable in patients who have a similar problem.

Aorto--bronchial fistula resulting from an accidental fall one year earlier

A 75-year-old woman presented with massive haemoptysis 12 months after tripping over her shopping trolley. CT scanning and transoesophageal echocardiography demonstrated a traumatic false aneurysm which was confirmed at surgery to be partially ruptured. Aortobronchial fistula is an unusual cause of massive haemoptysis. It should be considered particularly in patients known to have abnormalities of the thoracic aorta.

Aortobronchial fistula after coarctation repair and blunt chest trauma

A 34-year-old man had development of an aortobronchial fistula 17 years after patch aortoplasty for correction of aortic coarctation and 5 years after blunt chest trauma, an unusual combination of predisposing factors. The clinical presentation, characterized by dysphonia and recurrent hemoptysis, and the surgical findings suggested the posttraumatic origin of the fistula, which was successfully managed by aortic resection and graft interposition under simple aortic cross-clamping, associated with partial pulmonary lobectomy. When hemoptysis occurs in a patient with a history of an aortic thoracic procedure, the presence of an aortobronchial fistula should be suspected. Early diagnosis offers the only possibility of recovery through a lifesaving surgical procedure.

[Experience with surgery for congenital esophago-bronchial fistula with esophageal diverticulum in adult]

A 65-year-old female was admitted into our department with complaint of bloody sputum. An upper G-I series examinations and thoracic CT demonstrated an esophago-bronchial fistula with diverticulum located between the mid-esophagus and right B6. Following postero-lateral thoracostomy, the fistula was surgically removed and right lower lobectomy was carried out. No inflammatory changes were found in the surrounding tissues of the fistula and the diverticulum. Histological examination revealed that the fistula wall contained squamous epithelium and muscularis mucosa. These results suggested that this case was congenital esophago-bronchial fistula categorized as Braimbridge type I.

[Pancreatico-bronchial fistula with communication to a pseudoaneurysm of the arteria lienalis as a rare complication in chronic pancreatitis]

Thoracic manifestations of internal pancreatic fistulas caused by chronic pancreatitis are rare conditions. The three main types of these manifestations are mediastinal pseudocysts, pancreatico pleural fistulas and pancreaticobronchial fistulas. We report on one patient with the clinical presentation of all three thoracic internal pancreatic fistulas with a communication to a pseudoaneurysm of the splenic artery caused by chronic alcohol-related pancreatitis. Conservative therapy over four weeks was not successful. Resection of the pseudoaneurysm, debridement of the mediastinal pseudocyst and duodenum preserving resection of the pancreas treated all complications and prevents recurrence in this patient with chronic pancreatitis.

Congenital bronchoesophageal fistula in an adult

We present a rare case of a congenital bronchoesophageal fistula in a 54-year-old woman with a history of poor feeding tolerance since infancy and repeated pulmonary infections. She initially presented with epigastric and right upper quadrant abdominal pain. Her workup included a barium esophagogram that revealed a fistula between her midesophagus and a left lower lobe segmental bronchus. The fistula was divided, a left lower lobe superior segmentectomy was performed, and an intercostal muscle was placed over the esophageal closure. The patient noted an immediate decrease of postprandial coughing. Congenital respiratory esophageal fistulas that are not associated with esophageal atresia may persist into adulthood before they become clinically apparent. The diagnosis should be considered in certain individuals with suggestive symptomatology and unexplained respiratory pathology.

Pleural space irrigation and modified Clagett procedure for the treatment of early postpneumonectomy empyema

OBJECTIVE

The incidence of postpneumonectomy empyema is 5% to 10%. Approximately half of postpneumonectomy empyemas occur within 4 weeks of pneumonectomy. A bronchopleural fistula is found in more than 80% of the patients. The classic treatment of postpneumonectomy empyema includes parenteral antibiotics, drainage of the pleural space, removal of necrotic tissue, and open pleural packing for many weeks followed by obliteration of the empyema space with antibiotic fluid or muscle. This approach results in prolonged hospitalization, repeated operations, and significant morbidity. As a possible means of decreasing morbidity with the classic treatment of postpneumonectomy empyema, we studied the use of pleural space irrigation in these patients.

METHOD

In a 5-year period, we treated 22 patients with early postpneumonectomy empyema. All patients had a bronchopleural fistula. All patients underwent emergency drainage of the pleural space followed by thoracotomy, debridement of necrotic tissue, closure of the bronchial stump with absorbable monofilament suture, and pleural space irrigation. After a negative Gram stain from the pleural fluid, the pleural space was filled with 2 L of debridement antibiotic solution (DAB solution) (gentamicin 80 mg/L, neomycin 500 mg/L, and polymyxin B 100 mg/L), and the irrigation and drainage catheters were removed.

RESULTS

Twenty patients had negative Gram stains on day 9, and 2 patients had a negative Gram stain on day 16. The mean duration of hospitalization was 12.9 +/- 3. 4 days. There was no recurrence of empyema or a bronchopleural fistula.

CONCLUSIONS

Pleural space irrigation followed by obliteration of the pleural space with an antibiotic solution required one surgical procedure and resulted in significantly shorter hospitalization and decreased morbidity in patients with early postpneumonectomy empyema.

[A case of video-assisted thoracic surgery for congenital esophago-bronchial fistula]

A 42-year-old male was admitted to our hospital because barium esophagograpm showed an esophago-bronchial fistula with an esophageal deverticulum. He has had frequent episodes of cough at drinking water since childhood. A chest CT scan showed mild inflammatory change and bronchiectasis in the right S6. Division of the fistula by video-assisted thoracoscopic surgery (VATS) was performed. There was no evidence of inflammation and adherent lymph nodes around the fistula. This case was diagnosed as a congenital esophago-bronchial fistula by operative findings and clinical course. The fistula was dissected easily and divided by an auto-suturing instrument. The affected lung could be preserved. The patient was discharged on the 10th postoperative day. VATS is an effective treatment for the patients of congenital esophago-bronchial fistula (Braimbrige type I and II), if they are not accompanied with pulmonary abscess or pleural empyema.

Unusual presentation of hemoptysis in a 78-year-old with previous Nissen fundoplication

A 78-year-old individual, who had a previous transthoracic Nissen fundoplication 20 years earlier, presented to our institution with hemoptysis. Initial workup included chest roentgenogram, upper gastrointestinal series, and upper endoscopy, all of which were nondiagnostic. A repeat upper endoscopy diagnosed a gastrobronchial fistula by revealing a large gastric ulcer that penetrated into the lung parenchyma. The patient underwent surgery for takedown of the fistula. One of the most common symptoms associated with gastrobronchial fistula is hemoptysis, although insidious cough, recurrent pneumonia, or gastrointestinal bleeding are also observed. The most useful diagnostic study is an upper gastrointestinal series, which must be read with a high index of suspicion. Gastrobronchial fistula is most commonly a long-term complication from hiatal hernia repair. The most frequently used procedure for repair of this disorder is the Nissen fundoplication. This can be done from either an abdominal or transthoracic approach. When the procedure is done such that the gastric wrap is left above the diaphragm, serious complications can occur. These include gastric ulceration, gastric herniation with gastric outlet obstruction, slippage or perforation of the wrap, and gastrobronchial fistula. Because of these serious complications, the Nissen fundoplication with the wrap left above the diaphragm should only be used in certain situations, such as obesity and shortened esophagus.

Bronchogastric fistula, pulmonary sequestration, malrotation of the intestine, and Meckel's diverticulum--a new association

Two female children, each who had a bronchogastric fistula and pulmonary sequestration (communicating bronchopulmonary foregut malformation, CBPFM) and associated malrotation of the intestine and Meckel's diverticulum are presented. Each child also presented with severe gastroesophageal reflux. The association of malrotation of the intestine and Meckel's diverticulum with a CBPFM never has been reported as a distinct entity. The concept of association of anomalies is discussed briefly.
