Surgical treatment of metapneumonic pleural empyema

During a period of 13 years 54 patients have been treated for metapneumonic pleural empyema, namely 3 children (all boys), 31 men and 20 women. One patient was admitted in extremis heavily intoxicated after unsuccessful attempt at closed drainage. He died during thoracotomy for open drainage. All the remaining 53 patients were cured, 3 out of 18 by closed thoracostomy (Bülau), 12 out of 16 by open drainage and 37 by decortication which had to be combined with pulmonary resection 13 times. Local treatment of pleural empyema is aimed at the obliteration of the pleural space. This goal can best be accomplished: in the acute exudative stage of the disease (according to the American Thoracic Society) by closed thoracotomy, in the fibrino-purulent phase by open thoracotomy with rib resection and in the chronic organizing stage by decortication.     

Current indications for decortication in the treatment of empyema in children

Although most children with empyema respond to antibiotics and pleural drainage, a recognizable number fail to improve. This study reviews experience with ten children over the past 7 years who have been selected for lung decortication for refractory empyema. Decortication was performed because of lack of clinical improvement despite drainage and multiple antibiotics during an average 20-day preoperative hospitalization. Responsible organisms included beta-hemolytic Streptococcus, Streptococcus pneumoniae, and Hemophilus influenzae. A computerized tomographic (CT) scan of the chest was performed in the last eight patients and showed at least a 50% limitation of lung expansion by the products of the empyema in each case. Following decortication, chest tubes were removed, antibiotics stopped, and temperature and white blood cell count returned promptly to normal. The advantages of early decortication in selected patients with empyema who do not respond to antibiotics and drainage include low morbidity, shorter hospitalization, and excellent long-term results.     

Empyema thoracis: a problem with late referral?

BACKGROUND--Patients are often referred to thoracic units for management of empyema after the acute phase has been treated with antibiotics but without adequate drainage. This study evaluates the effects of delay in surgical treatment of empyema thoracis on morbidity and mortality. METHODS--Thirty nine consecutive patients were studied from January 1991 to June 1992. Two groups (group 1, 16 patients; group 2, 23 patients) were compared depending on the time spent under the care of other specialists before referral to the thoracic unit (group 1, seven days or less; group 2, eight days or more). The reasons for delay in referral were analysed. RESULTS--Four patients were treated conservatively with chest drainage alone (all in group 1). Thirty five patients required rib resection and drainage of their empyema (group 1, 12 patients; group 2, 23 patients). Nineteen (all in group 2) of the 35 patients who had rib resections went on to have decortication. The commonest cause of empyema was post-pneumonic (37 out of 39 patients). Staphylococcus aureus was the commonest organism isolated. Misdiagnosis (five patients), inappropriate antibiotics (six patients), and inappropriate placement of chest drainage tubes (three patients) all contributed to persistence and eventual progression of empyema. The overall mortality was 10% and mortality increased with age. The median stay in hospital was 9.5 days (range 7-12 days, n = 4) for patients treated with closed tube drainage only; 18 days (range 10-33 days, n = 16) for patients who had undergone rib resections and open drainage; and 28 days (range 22-49 days, n = 19) for patients who underwent decortication. The likelihood of having a staged procedure (antibiotics, closed tube drainage, open drainage with rib resection, and finally decortication) increased when closed tube drainage was persevered with for more than seven days. The total hospital stay was positively related with the time before referral for surgical treatment. Anaemia, low albumin concentrations, and worsening liver function were found in group 2 compared with group 1. CONCLUSIONS--Early adequate operative drainage in patients with empyema results in low morbidity, shorter stays in hospital, and good long term outcome. These patients should be treated aggressively and early referral for definitive surgical management is recommended.     

Primary thoracoscopic treatment of empyema in children

OBJECTIVE: The optimal treatment of pediatric empyema remains controversial. The objective of this study is to compare the use of conventional management versus primary thoracoscopic drainage and decortication in children with empyema. METHODS: Conventional management has consisted of chest drain insertion under general anesthesia plus intravenous antibiotics. Thoracoscopic drainage and decortication has consisted of primary thoracoscopic drainage and decortication plus antibiotics. The clinical course of 54 patients treated conventionally between 1989 and 1997 was compared with that of 21 patients treated by means of thoracoscopic drainage and decortication between September 2000 and September 2001. RESULTS: Results of the study demonstrated that patients in the drainage-decortication group had fewer invasive interventions per patient than those in the conventional management group (1.0 vs 1.26). Patients undergoing thoracoscopic drainage and decortication also had significantly shorter durations of intravenous antibiotic therapy (7.6 +/- 1.2 vs 18.2 +/- 7.5 days), chest tube drainage (4.0 +/- 0.5 vs 10.2 +/- 6.1 days), and hospital stays (7.4 +/- 0.8 vs 15.4 +/- 7.4). Moreover, there were no open thoracotomies and decortications in the thoracoscopic drainage and decortication group, whereas in the conventional management group 39% (21/54) of patients underwent an open procedure. CONCLUSION: Although the 2 groups were not prospectively randomized and they were treated in different time periods, the results of this study support the use of thoracoscopic surgery as the primary therapeutic modality in children presenting with pleural empyema. This strategy appears to offer significant benefits over conventional treatment in terms of duration of treatment and the need for more invasive surgery.     

Empyema: analysis of treatment techniques

Empyema is associated with a high mortality. To study the factors responsible for the failure of treatment, the authors reviewed 90 cases of nontuberculous thoracic empyema seen at the University of Western Ontario in London, between 1970 and 1980. The most common causes of empyema were bronchopulmonary infections (63%), complications of pulmonary surgery (14%) and secondary infections of hydrothoraces or hemothoraces (13%). In 51 patients (57%) the condition was acquired in hospital or was related to previous medical therapy. Nine cases were recognized only at autopsy. The treatment of empyema was assessed in 81 patients, who received an average of 2.2 antibiotics during the course of treatment. Five patients received antibiotics as the only therapy; one died. Seventy-two patients were treated by surgical drainage; 35 (49%) were cured and 18 (25%) subsequently died. Twelve of 18 decortication procedures were successful including 4 performed as a primary procedure and 8 as a secondary procedure. Five of seven patients who underwent thoracoplasty were cured. The overall mortality in the series was 23%. Prevention and early recognition of empyema may reduce the mortality. Patients who do not improve promptly with surgical drainage may benefit from early decortication.     

Postpneumonic empyema in childhood: selecting appropriate therapy

In order to identify appropriate treatment options for postpneumonic empyema, we reviewed the medical records and, when possible, obtained long-term follow-up chest radiographs and pulmonary function tests on children treated for empyema during the past 11 years. Fifty-one patients were treated in various ways, with antibiotics alone (N = 10), or in combination with tube thoracostomy (N = 23) or decortication (N = 18). Despite administration of appropriate antibiotics and establishment of pleural drainage, many children required prolonged hospitalization and eventual decortication. Based on this review, a scoring system was developed allowing early classification by severity of pleural disease. Factors found to be predictors of severe pleural disease include (1) low pleural fluid pH or (2) glucose; (3) presence of moderate or severe scoliosis or (4) pleural peel or parenchymal entrapment by chest radiography; and (5) infection due to anaerobes, gram-negative organisms, or mycoplasma. Complete opacification of a hemithorax on chest radiography and a pleural peel to thoracic ratio greater than 40% were also associated with severe pleural disease. In patients with mild disease (N = 7), response to antibiotics alone, rapid resolution of fever, and shorter hospital stays were observed. In patients with more severe infections (moderate = 22, severe = 22), decortication accomplished earlier defervescence, radiographic improvement, and hospital discharge than simple tube thoracostomy. No deaths or morbidity were associated with decortication, which could often be accomplished through a minithoracotomy. Follow-up chest radiographs and pulmonary fuction tests showed a prompt return to normal after decortication. This experience indicates utility of a pleural disease severity scoring system in selection of treatment options for children with postpneumonic empyema.(ABSTRACT TRUNCATED AT 250 WORDS)     

Early decortication in childhood empyema thoracis

Thoracic empyema is a life-threatening condition in paediatric surgical practice and the appropriate management still remains controversial. The authors reviewed 79 (37 boys, 42 girls) cases of empyema thoracis who underwent thoracotomy and decortication between 1990 and 2005. The initial diagnosis based on history, physical examination and radiology was confirmed by thoracentesis. Fever, cough and dyspnoea were the most common presenting symptoms. In all cases aerobic cultures were performed and Staphylococcus aureus was the most common microorganism isolated. All patients except three received antibiotics and tube drainage as an initial treatment. The decision for early decortication was based on persistence of fever, dyspnoea, air leakage and lack of resolution on CT scan, in spite of medical therapy and tube drainage, at the end of 10 days. All but one with wound dehiscence showed rapid recovery and they were discharged on the fifth to eighth postoperative days. In conclusion, early decortication is a safe and curative treatment in childhood empyema thoracis with low morbidity.     

Role of lung decortication in symptomatic empyemas in children

Despite appropriate antibiotics and pleural drainage, the condition of some children with empyema fails to improve. In a 5-year period, 10 children ranging in age from 2 to 16 years underwent lung decortication for a refractory, symptomatic empyema, which had developed 3 to 5 weeks after an initial pneumonic infiltrate. Responsible organisms included beta-hemolytic streptococci, Haemophilus influenzae, or Streptococcus pneumoniae in 6 children. Negative cultures were found in 4 children. The initial computed tomographic scan of the chest in 4 of 8 patients showed more than 75% limitation of lung expansion by the contents of the empyema cavity. In 4 other patients, an extensive pleural peel was seen on initial computed tomographic scan of the chest. Several studies also showed cystic lesions in the collapsed lung. Multiple computed tomographic scans in 3 patients confirmed the lack of clinical and chest roentgenographic improvement with conservative therapy. At decortication in each, the visceral and parietal pleural peel was completely removed, freeing the trapped lung. Two patients also had a concomitant lobectomy for a necrotic right upper lobe (1 patient) and left lower lobe (1). Clinical improvement was marked, with return of temperature, white blood cell count, and appetite to normal. Postoperative morbidity was minimal. Analysis of these patients in whom traditional conservative therapy failed suggested that the initial management during the early exudative phase was often delayed and was not aggressive enough from the standpoint of pleural drainage.(ABSTRACT TRUNCATED AT 250 WORDS)     

The role of early limited thoracotomy in the treatment of empyema

On the basis of clinical experience with 80 patients at Denver General Hospital from 1979 through 1984, we devised a three-part classification of empyema. Class I empyema (n = 12) is pleural effusion with pH less than 7.2 and with no bacteria. Patients with this type of empyema were treated with short-duration chest tubes. Further treatment was required in two of 12. There were no deaths. Class II (n = 28) is classic uniloculate empyema. Patients with this category of empyema were treated with chest tubes, with two deaths. Class III (n = 40) is complicated empyema, with multiple loculations. Tube thoracostomy failed more often than not; decortication was required in 10 of 18 patients treated with prolonged tube drainage. Limited thoracotomy for drainage and placement of tubes was done in 22 patients. Five required extension of the thoracotomy and decortication. All 22 had resolution of the empyema with no additional procedures. Limited thoracotomy immediately or during the first week of treatment is recommended for all multiloculated or complex empyemas.     

Behandlung des Pleuraempyems

Pleural empyema remains a frequently encountered clinical problem and is responsible for significant morbidity and mortality worldwide. Its diagnosis may be difficult; delays in diagnosis and treatment may contribute to morbidity, complications, and mortality. The management of parapneumonic effusion and empyema depends on timely, stage-dependent therapy and the underlying etiology. Thoracentesis and antibiotics remain the cornerstones of treatment in stage I disease. In the early fibrinopurulent phase (stage II) thoracoscopic methods should be considered. As treatment strategy for this stage, fibrinopurulent pleural empyema entails thorough debridement of multiloculated collections from the pleural cavity by video-assisted thoracic surgery. After evacuation of multilocular effusions and the removal of fibrin deposits with drainage by two intercostal chest tubes, irrigation treatment helps to achieve clarity of the pleural discharge. Open thoracotomy and decortication are reserved for organized, multiloculated empyema with lung entrapment (stage III disease). Early drain removal may lead to rapid symptomatic recovery and complete resolution.     

Is open thoracotomy still a good treatment option for the management of empyema in children?

BACKGROUND: The incidence of pediatric postpneumonic empyema increases, and there is little consensus on its management. Open thoracotomy has been linked with high morbidity and prolonged hospitalization. Our aim was to review the outcome after open thoracotomy and to provide a set of data for comparison with other treatment modalities. METHODS: Forty-four children (median age, 8 years, 2 months to 16 years) undergoing surgery for postpneumonic empyema between 1993 and 2002 in our unit were studied. RESULTS: The median time from onset of symptoms to admission in a pediatric unit was 8 days (range, 2 to 63 days), the median time from pediatric admission to surgical referral was 3 days (range, 0 to 19 days), and the median time from surgical admission to thoracotomy was 1 day (range, 0 to 2 days). Eight children had a chest drain before surgical admission. Six patients, who were referred late (19 to 69 days), had lung abscesses. A limited muscle sparing thoracotomy (44 patients), formal decortication (36 patients), lung debridement (5 patients), and lobectomy (1 patient) were performed. After thoracotomy, median time to apyrexia was 1 day (range, 0 to 27 days) and drain removal was 3 days (range, 1 to 16 days). A pathogen was isolated in 21 patients. There were no deaths. Four children with abscesses remained septic and had lobectomies (2 patients) and debridements (2 patients). The median postoperative hospital stay was 5 to 53 days. One child had postpneumonic empyema develop and had decortication 3 months postoperatively. At follow-up, all children were doing well and had satisfactory radiographs. The Kaplan-Meier 5-year and 10-year survival rate, freedom from any reoperation, and freedom from hospital readmission were 100%, 87%, and 98%, respectively. CONCLUSIONS: Open thoracotomy remains an excellent option for management of stage II-III empyema in children. When open thoracotomy is performed in a timely manner there is low morbidity and it provides rapid resolution of symptoms with a short hospital stay. However, delayed referrals may result in advanced pulmonary sepsis and a protracted clinical course. The late results are encouraging. Use of thoracoscopy or fibrinolysis should be considered on the basis of their own merit, not on the assumption of probable adverse outcomes after thoracotomy.     

Position paper on video-assisted thoracoscopic surgery as treatment of pediatric empyema

Pediatric empyema can be managed with a variety of modalities, and the evidence for an ideal management strategy is limited. Early or simple effusions can be treated with antibiotics alone or with drainage when respiratory distress occurs. Once fibrinopurulent empyema has developed, therapy may involve either chest tube placement with instillation of fibrinolytics or video-assisted thoracoscopic surgery with pleural decortication. In late or fibrotic empyema, an assumption persists that the fibrotic peel must be managed by decortication that can be done either thoracoscopically or through a minithoracotomy incision.This position paper is coauthored by the New Technology Committee of the American Pediatric Surgery Association. The goal is to discuss the ongoing controversies and summarize, in an evidence-based manner, the various treatment options and to suggest a reasonable therapeutic algorithm for the care of children with empyema.     

Decortication for childhood empyema. The primary provider's peccadillo

Of the 31 children treated for empyema thoracis secondary to pneumonitis at the Loma Linda University Medical Center, Loma Linda, Calif, from 1980 to 1990, 23 responded to prompt directed antibiotic therapy coupled with drainage, usually tube thoracostomy. All patients were cured clinically; some demonstrated residual pleural reaction with chest roentgenography or computed tomography that resolved over time. Decortication was necessary in eight severely ill children; three required concurrent lung resection for abscess. Distinct from the nonoperated group, there was a pattern of initial antibiotic trials in these patients averaging 6.5 different drugs plus delayed drainage of effusions. Delay in the initiation of antibiotic therapy was six times longer for the operated vs the nonoperated group. Delay to tube thoracostomy was 18 days for the decorticated children compared with 5.4 days for the nondecorticated children. All eight children responded completely and rapidly to their decortications. Roentgenographic changes lagged considerably behind the clinical course of the child, and computed tomographic scans provided better identification of chest tube placement but little information predictive of the need for decortication. Decortication for empyema seldom is necessary when a child is treated promptly with appropriate antibiotics directed by thoracentesis findings, and drainage, usually tube thoracostomy. The criterion for decortication is persistent sepsis, not the roentgenographic appearance of the chest.     

Current indications and results of pulmonary decortication for nontuberculous chronic empyema

Pulmonary decortication for nontuberculous chronic empyema has become a rare operation, whose indications and results are now rarely analysed and discussed. The authors report a series of 40 consecutive decortications performed over a period of 15 years. PATIENTS: 40 patients treated by pulmonary decortication over 15 years for nontuberculous chronic empyema secondary to pneumonia (27 cases; 2/3 of cases), post-traumatic haemothorax (5 cases), iatrogenic infection after pleural tap (5 cases) and septicaemia (3 cases). Chronic empyema had been present for an average of 6 months (1 to 60 months). Decortication was performed for drainage of persistent pleural suppuration in 22 cases and to release the encysted lung in 18 cases. Decortication, always comprising parietal pleural stripping and visceral decortication, lasted an average of 3 hours (2 to 8 hours), and was accompanied by mean bleeding of 1 litre (of 200 ml to 3.41). RESULTS: 27 patients (67%) had an uneventful postoperative course, with drainage for 6 days and a mean hospital stay of 13 days. 13 patients (33%) developed various complications, mainly re-expansion defects (10 cases), responsible for pyothorax in 4 cases, 3 of which required secondary drainage. One patient died from intestinal obstruction in a context of peritoneal carcinomatosis (operative mortality: 2.5%). 25 patients were reviewed with a mean follow-up of 54 months, with complete pulmonary re-expansion in 23 cases (92%) and a residual pouch in 2 cases. Vital capacity (VC) was evaluated in 8 patients, with a mean improvement of 40% (15 to 66%) in 6 patients, stable VC in one patient, and a 25% reduction in the last patient, a smoker and with chronic bronchitis. CONCLUSION: Pulmonary decortication is an effective, but relatively major operation to treat chronic encysted empyema. Encystment must be prevented by effective drainage of empyema, now facilitated by the possibility of early videothoracoscopic pleural debridement.     

Acute Empyema in Children Treated by Open Thoracotomy and Decortication

Acute nontuberculous empyema treated conventionally by thoracentesis, thoracostomy drainage, and antibiotics has an unacceptably high rate of morbidity and mortality. Early open thoracotomy to eliminate the empyema with decortication of the fibrinous peel and reexpansion of the lung has proven safe and effective for 25 years.The goals of treatment of acute nontuberculous empyema are: (1) to save life, (2) to eliminate the empyema, (3) to reexpand the trapped lung, (4) to restore mobility of the chest wall and diaphragm, (5) to return respiratory function to normal, (6) to eliminate complications or chronicity, and (7) to reduce the duration of hospital stay.Our studies confirm the normal values to be expected in patients who have had complete recovery from the acute empyema, and we lay to rest any concern that decortication might, in time, limit pulmonary function.We present the cases of 21 children who had acute and mature empyemas that were treated by open thoracotomy and decortication, with an average follow-up of 18 years, among whom there were no deaths or complications.     

Management of empyema in children

The antibiotic era has changed the incidence, causal factors, and gravity of empyema. Between 1977 and 1988, 27 children with empyema were surgically managed. Ten cases occurred after an operation (8 esophageal and 2 abdominal). There were 15 girls and 12 boys. The age range was newborn to 12 years. Symptoms included fever, cough, tube drainage postoperatively, anorexia, weight loss, chest pain, tachypnea, and lymphadenitis. Multiple aerobic and anaerobic organisms were cultured. Treatment included thoracentesis and antibiotics, tube thoracostomy, tube thoracostomy and bronchoscopy, decortication, or decortication with lobectomy. The total hospital stay averaged 28.3 days, and after decortication, 11.6 days. Empyemas in children frequently have multiple organisms and should be treated with broad-spectrum antibiotics while awaiting culture results. Thoracentesis and tube thoracostomy are often ineffective in curing the disease. Decortication can abbreviate hospital stay if performed promptly for persistent pleural sepsis.     

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.     

Surgical strategy of complex empyema thoracis.

BACKGROUND: The optimal treatment of empyema thoracis has been widely debated. Proponents of pleural drainage alone, drainage plus fibrinolytic therapy, video-assisted thoracoscopic surgical (VATS) debridement, and open thoracotomy each champion the efficacy of their approach. METHODS: This study examines treatment of complex empyema thoracis between June 1, 1994, and April 30, 1997. Twenty-one men and 9 women underwent 30 drainage/decortication procedures (14 open thoracotomies and 16 VATS) in treatment of their disease. Effusion etiology was distributed as follows: infectious-14; neoplastic-associated-7; traumatic-3; other-6. RESULTS: The mean preoperative hospital stay was 14 +/- 8.8 days, (11.4 +/- 6.5 days for VATS vs 16.8 +/- 10.2 days for thoracotomy). Hospital stay from operation to discharge for thoracotomy patients was 10.0 -/+ 7.2 days (median 8.5 days) and for VATS patients 17.6 -/+ 16.8 days (median 11 days). These differences were not statistically significant. Duration of postoperative thoracostomy tube drainage was 8.3 -/+ 4.6 days for thoracotomy patients and 4.7 -/+ 2.8 days in the VATS group (p = 0.01). Operative time for the thoracotomy group was 125.0 -/+ 71.7 minutes, while the VATS group time was only 76.2 -/+ 30.7 minutes. Estimated blood loss for the thoracotomy group was 313.9 -/+ 254.0 milliliters and for the VATS group 131.6 -/+ 77.3 milliliters. Three of the 30 patients (10.0%) required prolonged ventilator support (>24 hours). Morbidity included one diaphragmatic laceration (VATS group) and one thoracic duct laceration (thoracotomy). Two VATS procedures (6.7%) required conversion to open thoracotomy for thorough decortication. CONCLUSIONS: The surgical approach to empyema thoracis is evolving. In the absence of comorbid factors, the significantly lower requirement for chest tube drainage time in the VATS patients suggests that this modality is an attractive alternative to thoracotomy in the treatment of complex empyema thoracis.     

Current treatment of pediatric empyema

Pneumonia with complicated parapneumonic effusion and empyema is increasing in incidence and continues to be a source of morbidity in children seen in our institution. Current diagnostic modalities include chest radiographs and CT scanning with ultrasound being helpful in some situations. Exact management of empyema remains controversial. Although open thoracotomy drainage is well accepted in children, video-assisted thoracoscopic surgery (VATS) drainage has become more prevalent in the current era. Over the last 4 years, we have treated 58 children with intrapleural placement of pigtail catheters and administration fibrinolytics consisting of tissue plasminogen activator (tPA). Successful drainage and resolution of 54 of the 58 effusions was achieved with percutaneous methods alone. There was no mortality or 30-day recurrence. Mean hospital stay was 9.1 days (range 5 to 21) and mean chest catheter removal was 6 days post placement (range 1.5 to 20). Of the four patients that failed percutaneous tube therapy, 3 underwent video assisted thoracic surgery (VATS), and one had open thoracotomy with decortication. Based on our experience, tPA administered through a small bore chest tube for drainage of complicated parapneumonic effusions has become our standard practice. We reserve VATS for treatment failures and open thoracotomy and decortication for patients with VATS failure.     

Management of tuberculous empyema.

OBJECTIVE: In an attempt to establish a treatment protocol for tuberculous empyema, we retrospectively reviewed our experience over a 3-year period. METHODS: Between January 1996 and December 1998, 26 patients (23 male and three female) with an average age of 33.8 years (range 18-61 years) presented with tuberculous empyema. The empyema was right-sided in 13, left-sided in 12 and bilateral in one patient. Patients presented with respiratory symptoms for a mean duration of 4.43 months (range 1-48 months). All patients had a computerized scan of the chest and managed according to the stage of empyema. RESULTS: In patients with exudative empyema (n=4) the fluid was aspirated, but one patient required intercostal tube (ICT) drainage for 6 days. There were four patients with fibrinopurulent empyema treated with thoracoscopic drainage with a mean post-operative stay of 8 days (range 4-12 days). In the organizing stage (n=18), initial drainage with large ICT was performed. The pleura was less than 2 cm in thickness in eight patients, for which repeated installation of streptokinase was performed (three to seven times). Satisfactory results were achieved in six patients (75%) and the remaining two required decortication. Of the ten patients with thick cortex, one required a window and nine had decortication, two of which had additional lobectomy and two had pneumonectomy. All patients fully recovered with no mortality and with a mean duration of drainage of 18 days (range 3-61 days). CONCLUSION: Its stage and the state of the underlying lung should guide surgical treatment for tuberculous empyema. This protocol aims to achieve cure utilizing the least invasive approach and acceptable hospital stay.
