A new technique for muscle flap closure of the empyema space in complicated chronic bronchopleural fistula

OBJECTIVES: It is difficult to close the empyema space once it is opened, especially in cases complicated with a chronic bronchopleural fistula. A muscle flap closure is generally employed to prevent this situation. However, this operation occasionally fails because the space newly recurs around the fistula due to atrophic change occurring in these translocated muscles. The aim of the present new technique was to prevent inspiratory pressure from the inside of the bronchus by bronchial emboli, and help the adhesion between the fistula stump and the muscle flap, even if they have become atrophic and no longer have sufficient volume to fill the entire empyema space. METHODS: We carried out fiberscopic embolism of causative bronchioles followed by muscle flap closure in 4 patients in whom open drainage had already been performed against parapneumonic empyema within the bronchial fistula. The bronchial fistula was plugged from the inside of the bronchus by silicon material, and stainless steel wire was used to connect this plug tightly to the muscle flaps, so that the fistula was sandwiched between them. In all cases, we succeeded in complete closure of the bronchial fistula and empyema space without using the omentum, and there has been no recurrence. CONCLUSION: The presented new technique was beneficial for achieving muscle flap closure of the empyema space with a chronic bronchopleural fistula.     

Endobronchial closure of postoperative bronchopleural fistula using vascular occluding coils and n-butyl-2-cyanoacrylate

We report herein 2 patients with intractable postoperative bronchopleural fistula with empyema after lobectomy or subsegmentectomy. The patients underwent several treatments including thoracotomy, but the fistula closure was not successful. Finally, the bronchopleural fistula was successfully treated by endobronchial closureusing vascular occluding coils and n-butyl-2-cyanoacrylate (Histoacryl).     

Microvascular vastus lateralis muscle flap for chronic empyema associated with a large cavity

Thoracic empyema can be disabling and may need microvascular free flaps in some intractable cases. After repeated failure of conventional thoracic surgical procedures, 2 patients with empyema were treated with microvascular free vastus lateralis muscle flaps for obliteration of the large empyema cavity. The reconstruction was successful in wound closure and eradication of infection. The donor site morbidity was minimal, and the patients resumed normal daily activities. Microvascular vastus lateralis muscle flap is the best option if free flaps are required for reconstruction of empyema.     

Closure method of bronchopleural fistula with omental pedicle flap in three cases following pneumonectomy

This report presents that successful closure of bronchopleural fistula was performed by using omental pedicle flap for three postpneumonectomy patients. In our department, these cases were experienced among 142 pneumonectomies from January 1984 to July 1989. The initial operations were a pleuropneumonectomy for empyema, a pneumonectomy and a sleeve pneumonectomy for lung cancer. Our technique was direct closure of bronchopleural fistula with omental pedicle flap without thoracoplasty. Although none of them had recurrence of bronchopleural fistula nor other complications in postoperative course, two patients died of cancer.     

Axillary artery to contralateral axillary vein graft fistula in chronic hemodialysis patients

BACKGROUND: Vascular access failure is a severe and common complication for hemodialysis patients. The possible vascular access sites are limited in dialysis patients. Axillary artery to contralateral axillary vein arteriovenous fistula (AVF) is one of the possibilities. However, the clinical outcome of this procedure is still un-defined. OBJECT: The purpose of this study is to review the clinical outcome of axillary artery to contralateral axillary vein AVF as a hemodialysis vascular access. PATIENTS AND METHODS: We retrospectively reviewed native or graft arteriovenous fistula records for chronic hemodialysis patients at Chang Gung Memorial Hospital in Kaohsiung, Taiwan, from January 1986 to March 2001. Records were reviewed for all chronic hemodialysis patients, with more than 2000 individuals receiving more than 10,000 fistulas. Eight patients received axillary artery to contralateral axillary vein AVF. RESULTS: The mean age for these patients was 61.7 +/- 16.3 year-old at time of surgery. All patients had received multiple native or graft arteriovenous fistula creation. The 2-year and 4-year AVF graft survival is 87.5% and 43.8% respectively. One patients developed brachial plexopathy after operation. Another patient had venous hypertension distal to the AVF site. Both patients were managed conservatively. There is no AVF-related mortality in these patients. CONCLUSION: We conclude that axillary artery to contralateral axillary vein graft fistula may be a feasible alternative choice for chronic hemodialysis access.     

Transsternal transpericardial approach for the repair of bronchopleural fistula with empyema

BACKGROUND: Numerous surgical approaches have been reported for the repair of bronchopleural fistula. Recently the transsternal transpericardial approach has shown great promise with its positive results in cases of bronchopleural fistula complicated with empyema. The aim of this retrospective study was to assess the results of bronchopleural fistula treatment using the transsternal transpericardial approach. METHODS: Bronchopleural fistula developed in 16 of the 172 patients who had pneumonectomy between 1982 and 1996. In one case closure with fibrin sealant by bronchoscopy was tried. In the remaining cases fistula was closed by the transsternal transpericardial approach. RESULTS: The interval between pneumonectomy and fistula occurrence was 10 days or less in 5 patients and 10 days to 1 month in 11 patients. In all patients the empyema space was treated by continued drainage through the thoracostomy tube. Fibrin sealant was tried unsuccessfully for closure of moderate-sized bronchopleural fistula in one case. In three cases of right bronchopleural fistula, carinal resection and anastomosis of the trachea to the left main stem bronchus were performed. In the remaining cases bronchopleural fistula was closed using a hand suture technique. One patient died within 30 days after operation (6.25%) because of renal insufficiency. There was no recurrence of bronchopleural fistula. CONCLUSIONS: Transsternal transpericardial approach seems to be a safe and effective method with an easier technique in cases of bronchopleural fistula complicated with empyema. It has the added advantage of less recurrent fistula formation and enables resection in cases without sufficient bronchial stump.     

Microsurgical medialis pedis flaps for reconstruction of soft-tissue defects in the hand.

The medialis pedis flap (MPF) has been used for the reconstruction of soft-tissue defects in the hand since 1990. From January 1997 through January 2000, 19 patients (15 male, 4 female) with hand injuries underwent microsurgical MDF reconstruction at Chang Gung Memorial Hospital. There were finger injuries in 16 patients and palm defects in 3 patients. The mean patient age was 32.6 years (age range, 16-58 years). Flap size ranged from 4.5 x 2 cm to 7 x 6 cm (mean, 6 x 2.8 cm). Only one flap had partial loss. The donor site was closed primarily in 9 patients, and was closed using a split-thickness skin graft in 9 patients and a full-thickness skin graft in 1 patient. At a mean follow-up of 13 months, the protective sensation was 16 mm using the static two-point discrimination test and was 10 mm using the moving two-point discrimination test. Based on this retrospective study the authors conclude that (1) the MPF has the advantages of thin and glabrous skin, (2) the size of pedicle is compatible with the recipient vessel in the hand, (3) there is low donor site morbidity, and (4) achieving protective sensation is possible.     

Free rectus abdominis musculocutaneous flap for chronic postoperative empyema

Chronic postoperative empyema remains a challenge for thoracic surgeons. Free musculocutaneous flap transplantation may provide a good alternative option in the treatment of these refractory complications after pulmonary resections. Three patients with chronic postoperative empyemas combined with bronchopleural fistulas underwent obliteration of the empyema tracts with free rectus abdominis musculocutaneous flap transplantations. Surgical treatment was a two-stage procedure that consisted of open-window thoracostomy, followed by obliteration of the pleural cavity using a free transfer of the ipsilateral, full-thickness rectus muscle flap and microanastomoses. No postoperative complications occurred, and the 3 patients resumed normal daily activities. Free rectus abdominis musculocutaneous flap transplantation is safe and effective in the management of chronic postoperative empyema with bronchopleural fistula.     

Management of postpneumonectomy bronchopleural-cutaneous fistula with a single free flap.

A variety of local flaps have been described for chest wall and bronchopleural fistula reconstruction. When local options cannot be used because of previous surgery, trauma, radiation, or body habitus, free flaps become an acceptable option. The authors report a case of persistent bronchopleural-cutaneous fistula treated with a free latissimus dorsi musculocutaneous flap that obliterated the right chest cavity, closed the site of empyema drainage, and aided healing of a bronchopleural fistula. Surgical technique including anastomosis to the innominate vein is described.     

Treatment of postpneumonectomy empyema: the case for fenestration.

In Mearnskirk Hospital, Glasgow, 29 patients with postpneumonectomy empyema were treated by fenestration in a 12-year-period. Seven of these were not considered fit enough for definitive closure and died of continuing disease or respiratory infection. Twenty-two patients went on to closure of their fenestra, and in 17 (77%) the pneumonectomy space was rendered permanently sterile. If the empyema recurred treatment was repeated but proved less successful. Fenestration is an effective method of dealing with postpneumonectomy empyema, but also has several other advantages, particularly if the empyema is associated with a bronchopleural fistula.     

Transsternal transpericardial closure of a postlobectomy bronchopleural fistula

We report a case of chronic empyema and bronchopleural fistula after lobectomy for tuberculosis. The patient had undergone four different surgical procedures to correct his bronchopleural fistula during an interval of seven years. Finally, he had a successful closure of the fistula using the transsternal transpericardial approach.     

Thirty-eight free fasciocutaneous flap transfers in acute burned-hand injuries

The benefits of free flap transfers in the acute burn injury are early wound closure, early mobility, reduced hospitalization, and possibly limb salvage. This retrospective study will attempt to provide principles to the use of free fasciocutaneous flap for the reconstruction of acute burned-hand injuries. Between 1995 and 2004, 5521 patients were admitted to the burn unit at Linkou Chang Gung Memorial Hospital. Of these, 38 patients (0.7%) patients received free fasciocutaneous flap transfers. Each patient's chart was reviewed the following data: age, gender, burn injury type, percentage of the burned area to total body surface area, flap type, operations prior to free flap coverage, the size and location of recipient area, timing of free flap coverage, operative time, duration of hospital stay, complications, flap survival and returning to work. All 38 free flaps survived and healed well. Three flaps with partial necrosis due to wound infections required subsequent debridement and skin grafting. Arterial thrombosis occurred in one patient and was salvaged successfully. Minimal donor-site morbidity with no intraoperative mortality was observed. Free fasciocutaneous flap transfer is a safe, efficacious one-stage reconstruction for acute burned-hands with satisfactory aesthetic and functional outcomes. Flap survival is not affected neither by the etiologies of burn nor the timing of free flap coverage.     

Incidental positive internal mammary lymph nodes: a multiple international institutional investigation

The internal mammary lymph node is the second most frequent site of nodal metastasis. With an increase in breast free flap reconstruction utilization of the internal mammary vessels, identification of these internal mammary lymph node metastases will become more prevalent. A chart review documented 75 free transverse rectus abdominis myocutaneous flaps cases performed at Kaiser Bellflower from 1998 to 2004. Between March 2000 and January 2006 there were 157 autologous breast reconstructions (122 DIEP flaps, 10 GAP flaps, 15 SIEA flaps, 7 free transverse rectus abdominis flaps, and 1 SCIA flap) using internal mammary vessels as the recipient site at the Chang Gung Memorial Hospital. A literature review was conducted to survey the current protocols in the surgical, oncological, and radiological communities. A population of 232 patients with breast reconstruction via free flaps was identified. The age range was 29 to 65 years. With the exception of the five cases presented, no other incidence of positive internal mammary lymph nodes was identified. Failure to account for the status of the internal mammary lymph nodes may risk understaging and preclude appropriate treatment stratification. With more frequent utilization of the internal mammary vessels, discussions regarding breast reconstruction should take this new oncological focus into consideration.     

Postpneumonectomy empyema. The role of intrathoracic muscle transposition

Forty-five patients (36 male and nine female) were treated for postpneumonectomy empyema. All were initially managed with the first stage of the Clagett procedure (open pleural drainage). In 28 patients with associated bronchopleural fistula the fistula was closed and reinforced with muscle transposition at the time of open drainage. Seven patients had multiple flaps. The serratus anterior muscle was transposed in 28 patients, latissimus dorsi in 11, pectoralis major in four, pectoralis minor in one, and rectus abdominis in one patient. After the fistula was closed and the pleural cavity was clean, the second stage of the Clagett procedure (obliteration of the pleural cavity with antibiotic solution and closure of the open pleural window) was done. The number of operative procedures ranged from 1 to 19 (median 5.0). Length of hospitalization ranged from 4 to 137 days (median 34.0 days). There were six operative deaths (mortality rate 13.3%), none in the patients who had both stages of the Clagett procedure. Follow-up of the 39 operative survivors ranged from 2.1 to 90.2 months (median 21.8 months). Eighty-four percent of patients in whom the Clagett procedure was completed (26/31) had a healed chest wall with no evidence of recurrent infection. The bronchopleural fistula remained closed in 85.7% of patients (24/28). There were 19 late deaths, none related to postpneumonectomy empyema. We conclude that the Clagett procedure remains safe and effective in the management of postpneumonectomy empyema in the absence of bronchopleural fistula and that intrathoracic muscle transposition to reinforce the bronchial stump is an effective procedure in the control of postpneumonectomy-associated bronchopleural fistula.

The thigh as a model for free style free flaps

Following a set of principles, free style free flaps may be harvested from any region of the body where a Doppler signal is heard. By using a retrograde dissection technique, the skin vessel is traced through its subfascial course (intramuscular or septocutaneous), until adequate length or vessel size is achieved. If a "free style free flap" is not originally planned, this approach can be usedwhen anatomic variations or unexpected events are encountered. The thigh, a region that is familiar to the surgical team at Chang Gung Memorial Hospital, was chosen as the site to begin exploring this style of flap harvest. Nine flaps were harvested as free style free flaps from the thigh and were used successfully for the reconstruction of complex defects.     

Management of empyema cavity with the vacuum-assisted closure device

Management of empyema after pulmonary resection remains a challenging problem. Along with mandatory drainage of the thoracic cavity and investigations to rule out bronchopleural fistula, a reliable method of thoracic cavity closure is needed. The open thoracic window and Eloesser flap techniques rarely represent definitive therapy. Muscle flap and thoracoplasty procedures may provide well-vascularized tissue to close bronchopleural fistula and obliterate the empyema cavity, but they are quite complex and involve significant patient morbidity. We report a case of empyema without bronchopleural fistula after lobectomy in which the vacuum-assisted closure device was used to achieve complete wound healing after open drainage.     

Clinical experience of omental pedicle flap for bronchopleural fistula

We present two patients who underwent the omental pedicle flap method for bronchopleural fistula. The first case was a 61-year-old man who developed empyema with bronchial fistula due to recurrent tuberculosis resisted to chemotherapy. He underwent complete muscle and omental flap closure of empyema space. The second case was a 63-year-old man who underwent pneumonectomy for adenocarcinoma of the lung. About two weeks after the operation, a bronchopleural fistula developed at the bronchial stump. He underwent complete omental flap closure of fistula. They are doing well 18 and 9 months following operation, respectively. The omental pedicle flap method is clinically useful as a closure method for bronchopleural fistula because of excellent blood supply of the omentum.     

Treatment of bronchopleural fistula after pneumonectomy

Breakdown of the closure of the main-stem bronchus after pneumonectomy is a dreaded complication, and empyema and bronchopleural fistula frequently develop in patients who survive. Management of these fistulas remains a formidable therapeutic challenge, which has been approached with a variety of surgical techniques. We report our experience with anterior transpericardial closure, emphasizing the ability to expose either main-stem bronchus by this approach. The case histories of three patients who had bronchopleural fistula after pneumonectomy are presented. The first patient had left pneumonectomy for complicated tuberculosis; the second had right pneumonectomy for neoplasm; and the third had right pneumonectomy for trauma. All fistulas were treated surgically via a median sternotomy and transpericardial approach to the distal trachea. The posterior pericardium was divided between the superior vena cava and aorta. In-continuity staple closure (with two lines of staples) of the proximal main-stem bronchus was employed in all cases. Two patients remain clinically well 21 and 17 months after the operation. The third patients did well initially but developed a recurrent bronchopleural fistula 2 1/2 months after the operation and has required repeat closure with pedicled muscle flaps. In postpneumonectomy bronchopleural fistula, the anterior, transpericardial approach to bronchial closure has several advantages: the relatively well-tolerated median sternotomy, the avoidance of dealing directly with areas of postoperative scarring and the devascularized bronchial stump, the avoidance of areas of chronic sepsis, and the avoidance of thoracoplastic surgical deformity of the chest wall, with possible associated compromise in pulmonary function. Our experience also indicates that either main-stem bronchus is accessible through an approach between the superior vena cava and aorta, without division of either pulmonary artery.     

Transsternal transpericardial closure of a postpneumonectomy bronchial fistula in a patient who underwent pneumonectomy because of a war injury

Most common causes of intrathoracic empyema include pulmonary infections and postoperative bronchopleural fistulas complicating a lung surgical resection, mainly pneumonectomy, as a result of the failure of the bronchial stump to heal. A 22-year-old Serbian patient presented with chronic posttraumatic empyema. Two years before during a war, he experienced chest injury due to a firearm wound, with massive intrathoracic bleeding and need for emergency left pneumonectomy. Empyema with a bronchopleural fistula occurred during the postoperative course. The patient underwent left open window thoracostomy with a daily bandage change. Here we report the treatment of the bronchopleural fistula using sequential surgical approach including transsternal transpericardial closure of the fistula followed by reconstruction of the chest wall with a regional muscle flap. Our case report highlights the feasibility and efficacy of the transsternal surgical approach to treat postpneumonectomy bronchopleural fistula, thereby avoiding the direct approach to the bronchial stump through the infected pneumonectomy cavity.
