Intrapleurally administered streptokinase in the treatment of acute loculated nonpurulent parapneumonic effusions.

Adequate pleural drainage is believed to be an essential component of the management of low pH-low glucose parapneumonic effusion. Parapneumonic effusions may become loculated rapidly, preventing adequate drainage with a single chest tube. Administration of intrapleural streptokinase may be effective in promoting drainage for loculated, nonpurulent low pH-low glucose parapneumonic effusions when fibrin adhesions may not yet be organized. Intrapleural streptokinase was used in 12 patients with relatively large, symptomatic, loculated, nonpurulent parapneumonic effusions in whom the initial thoracentesis demonstrated a pH less than or equal to 7.0 and/or glucose less than or equal to 40 mg/dl, and when inadequate drainage was demonstrated roentgenographically despite tube thoracostomy. Mean pleural fluid WBC was 9,750/mm3 (range, 1 to 27 K), and pleural fluid glucose and pH were 33 +/- 21 mg/dl and 6.95 +/- 0.19, respectively. A solution of streptokinase, 250,000 units in normal saline, was given intrapleurally via the chest tube. Effectiveness of intrapleural streptokinase was assessed radiographically and by monitoring the volume of fluid drained from the chest tube after streptokinase instillation. A greater than 50% improvement in the CXR was seen in nine of 12 patients after intrapleural administration of streptokinase. The volume of fluid out in the first 48 h post-streptokinase was 849 +/- 836 ml (range, 100 to 3,000). In addition, clinical improvement (decreased chest discomfort, less dyspnea, or reduced fever) was noted in eight of 12 patients after streptokinase treatment. We conclude that intrapleural administration of streptokinase is an effective adjunct to the management of nonpurulent, loculated parapneumonic effusions that may reduce the need for multiple chest tubes or surgical drainage.

Sequential treatment of a simple pneumothorax.

In a prospective investigation of isolated simple pneumothorax, the treatment of 35 patients with a total of 37 pneumothoraces was studied. A standardized sequential treatment approach was followed for evacuation of the pneumothorax and maintenance of lung reexpansion. The protocol involved catheter placement using a Seldinger technique, aspirations, and documentation of reexpansion by chest radiography and observation. Reaccumulation of air was treated with Heimlich valve attachment to the catheter at intrapleural pressure and further observation. Continued air leak following Heimlich valve attachment was treated with chest catheter suction using a Pleurovac at -20 cm H2O pressure. Chest tube thoracostomy was performed for continued failure of reexpansion. In 22 of the 37 pneumothoraces (59%) simple catheter aspiration maintained lung reexpansion without complications. In the remaining 15 pneumothoraces (41%), seven (47%) responded to Heimlich valve attachment, and three (20%) maintained expansion with chest catheter suction. Chest tube thoracotomy was required to maintain expansion in 33% (five) of those who failed catheter suction (14% of all pneumothoraces studied). Patients treated successfully with simple catheter aspiration were sent home. Patients requiring a Heimlich valve, chest catheter suction, or chest tube thoracostomy were hospitalized. Use of these catheter techniques resulted in lower cost and was associated with shorter hospitalizations than in chest tube thoracostomy. Our study suggests that sequential treatment of simple pneumothorax should be considered as a cost-effective and therapeutically successful alternative to immediate chest thoracostomy in selected cases.

The value of chest roentgenography in the diagnosis of pneumothorax after thoracentesis.

PURPOSE: We sought to assess the yield of chest roentgenography for the detection of pneumothorax among hospitalized patients with pleural effusion who have undergone diagnostic or therapeutic thoracentesis. SUBJECTS AND METHODS: We performed a prospective study of 506 thoracentesis procedures in 370 patients. After the procedure, each operator filled out a note recording patient data and the characteristics of the thoracentesis. A chest radiograph was performed within 12 hours after the procedure in all patients. RESULTS: Eighteen (4%) pneumothoraces occurred in 17 patients, 9 (2%) of which required chest tube drainage. Of the 488 patients without symptoms, only 5 (1%) developed a pneumothorax, only 1 of which required chest tube drainage. By contrast, of the 18 patients with symptoms, 13 developed a pneumothorax, 8 of which required chest tubes. There were two independent predictors of pneumothorax: presence of symptoms (odds ratio [OR] = 250; 95% confidence interval [CI]: 65 to 980) and male gender (OR = 5.4; 95% CI: 1.9 to 69). CONCLUSIONS: Among the symptom-free patients in our sample, the risk of developing pneumothorax with clinical consequences was so low that the practice of routine chest roentgenography may not be justified.

A method for mediastinal drainage after cardiac procedures using small silastic drains.

BACKGROUND: It has been standard teaching in cardiac surgery that drainage of the mediastinum following cardiac surgical procedures is best accomplished using rigid large-bore chest tubes. Recent trends in cardiac surgery have suggested less invasive approaches to a variety of diseases. Difficult drainage problems in the field of general surgery including hepatic and pancreatic collections have been drained successfully with smaller flexible drains for many years. Additionally, many difficult to reach collections in the chest have been drained by invasive radiologists using small pigtail catheters. METHODS: We have introduced drainage of the mediastinum using 10-mm flexible, flat, fluted Blake drains. To date, we have used these drains in more than 100 cardiac operations including coronary artery bypass grafting, valve repair/replacements, combined coronary artery bypass grafting/valve operations, heart transplants, septal defects, and mediastinal tumors. RESULTS: We have demonstrated that this form of drainage is as good as using large-bore chest tubes with no significant risk of bleeding or tamponade. Additionally, use of these tubes is less painful, allows more mobility, and earlier discharge with functioning drains in place if necessary. CONCLUSIONS: Larger chest tubes are not necessarily better when it comes to draining the mediastinum. The actual area of ingress through the sideholes is considerably less than the surface area provided by the fluted Blake drain. We believe that this system can replace standard chest tubes.

What is the advantage of a thoracoscopic lobectomy over a limited thoracotomy procedure for lung cancer surgery?

BACKGROUND: To clarify any advantages of video-assisted thoracoscopic surgery (VATS) over anterior limited thoracotomy (ALT) for lobectomy in lung cancer, we compared the two procedures in a retrospective analysis. METHODS: Sex- and age-matched (+/- 5 years) lung cancer patients in clinical stage I who underwent lobectomy by means of VATS (n = 33) or ALT (n = 33) were compared in terms of the number of resected lymph nodes, operating time, intraoperative blood loss, duration of postoperative chest tube drainage, and chest pain. Pain was evaluated using a visual analog scale and analgesic requirements. Vital capacity (VC), respiratory muscle strength, and results of a 6-minute walking (6 MW) test were also compared preoperatively and 1 and 2 weeks postoperatively. RESULTS: Compared with the ALT group, the VATS group experienced less pain between postoperative day (POD) 1 and POD 7 (p < 0.05 to 0.001) and had lower analgesic requirements up to POD 7 (p < 0.001). However, there were no significant differences in pain on POD 14. There were also no significant differences in intraoperative factors or in the postoperative impairment of VC, respiratory muscle strength, and 6 MW test results. CONCLUSIONS: Although VATS lobectomy reduces chest pain during the first week after surgery compared with ALT, this advantage is lost within 2 weeks. Both techniques result in similar impairments of pulmonary function, respiratory muscle strength and walking capacity. Therefore, if curative resection of lung cancer by VATS would be technically difficult for any reason, including the surgeon's skill and experience, a limited open thoracotomy would be preferable from the standpoints of safety and the patient's prognosis.

Performance of advanced trauma life support procedures in microgravity.

BACKGROUND: Medical operations on the International Space Station will emphasize the stabilization and transport of critically injured personnel and so will need to be capable of advanced trauma life support (ATLS). METHODS: We evaluated the ATLS invasive procedures in the microgravity environment of parabolic flight using a porcine animal model. Included in the procedures evaluated were artificial ventilation, intravenous infusion, laceration closure, tracheostomy, Foley catheter drainage, chest tube insertion, peritoneal lavage, and the use of telemedicine methods for procedural direction. RESULTS: Artificial ventilation was performed and appeared to be unaltered from the 1-G environment. Intravenous infusion, laceration closure, percutaneous dilational tracheostomy, and Foley catheter drainage were achieved without difficulty. Chest tube insertion and drainage were performed with no more difficulty than in the 1-G environment due to the ability to restrain patient, operator and supplies. A Heimlich valve and Sorenson drainage system were both used to provide for chest tube drainage collection with minimal equipment, without the risk of atmospheric contamination, and with the capability to auto-transfuse blood drained from a hemothorax. The use of telemedicine in chest tube insertion was demonstrated to be useful and feasible. Peritoneal lavage using a percutaneous technique, although requiring less training to perform, was found to be dangerous in weightlessness due to the additional pressure of the bowel on the anterior abdominal wall creating a high risk of bowel perforation. CONCLUSIONS: The performance of ATLS procedures in microgravity appears to be feasible with the exception of diagnostic peritoneal lavage. Minor modifications to equipment and techniques are required in microgravity to effect surgical drainage in the presence of altered fluid dynamics, to prevent atmospheric contamination, and to provide for the restraint requirements. A parabolic simulation system was developed for equipment and procedure verification, physiological research, and possible crew medical officer training in the future.

Duration of pneumothorax as a complication of CT-guided lung biopsy.

The purpose of this study was to determine management guidelines for biopsy-induced pneumothorax with the assistance of manual aspiration, mainly based on the duration of complicated pneumothorax. Data from 388 consecutive percutaneous needle lung biopsies were examined. Patients with pneumothorax on postbiopsy chest CT images underwent percutaneous manual aspiration with an 18-G i.v. catheter. Frequency and management of biopsy-induced pneumothorax and period to its disappearance were reviewed. Postbiopsy pneumothorax occurred in 133 of 388 (34.3%) procedures. Manual aspiration in 72 of these 133 patients was carried out immediately after biopsy. The pneumothorax had resolved completely on follow-up chest radiographs without chest tube placement in 121 of the 133 pneumothoraces (91.0%). In cases requiring chest tube, the mean period from biopsy until resolution of the pneumothorax was 6.0 +/- 5.3 days, but was only 2.4 +/- 2.9 days when chest tube placement was not needed. Specifically, time until recovery was short both in those not requiring manual aspiration (2.1 +/- 3.4 days) and in those with a pneumothorax that disappeared completely or almost completely after manual aspiration (1.9 +/- 2.0 days). The almost equally short recovery periods in patients not requiring manual aspiration and those requiring immediate manual aspiration indicates the value of rapid management.

Prophylactic positive end-expiratory pressure and reduction of postoperative blood loss in open-heart surgery.

BACKGROUND: Various strategies have been introduced to minimize transfusion requirements in cardiac surgery. One strategy is the use of positive end-expiratory pressure (PEEP) postoperatively. Currently, PEEP is used in many centers to control increased mediastinal chest-tube drainage. The purpose of this study was to determine whether the prophylactic application of a PEEP of 10 cm H2O compared with a PEEP of 5 cm H2O in the immediate postoperative period reduces mediastinal chest-tube output without causing clinically significant hemodynamic compromise. METHODS: We prospectively studied 84 elective coronary artery bypass grafted patients and randomized treatment groups to a PEEP of 5 or 10 cm H2O. Forty-four patients were assigned a PEEP of 5 cm H2O and 40 patients received a PEEP of 10 cm H2O. RESULTS: Preoperative, intraoperative, and postoperative demographics were similar between groups. There was no statistically significant difference between the 5 cm H2O PEEP group and the 10 cm H2O PEEP group with regard to chest-tube output at 6 hours, at 24 hours, or in total output. There was no statistical difference in hemoglobin levels immediately postoperatively, at 8 hours, or at 36 hours. CONCLUSIONS: This study demonstrates that the use of postoperative PEEP levels of 10 cm H2O, although safe, does not reduce chest-tube output or transfusion requirements.

Pleural tenting following upper lobectomies or bilobectomies of the lung to prevent residual air space and prolonged air leak.

OBJECTIVE: Apical residual air space and prolonged air leak are not uncommon entities following resection of upper lobe of the lung. This study was carried out to observe the efficacy of pleural tenting in preventing these problems. METHODS: This is a prospective randomised study. Pleural tenting after upper or upper and middle lobectomies was performed in 20 patients. In another 20 patients who underwent upper lobectomy or bilobectomy, pleural tenting was not performed. Both groups were compared in respect to durations of postoperative chest tube drainage and hospital stay, amount of total pleural drainage, and the presence of need for any additional intervention for prolonged air leak. RESULTS: Age, sex, pathology and pulmonary function tests of two groups were similar. Duration of chest tube drainage was shorter in whom pleural tenting was performed when compared to whom pleural tenting was not performed (4.3+/-0.16 days versus 7.40+/-0.68 days, P<0.0001). Mean hospital stay was shorter in tented group (7.60+/-0.4 days versus 9.35+/-0.6 days, P=0.024). Although the mean amount of total pleural drainage was less in tented group (667.5+/-57.7 ml versus 802.5+/-83.3 ml, P=0.1911), the difference was not statistically significant. Three (15%) patients in non-tented group needed an apical chest tube insertion in postoperative period for prolonged air leak with an apical pleural space. Asymptomatic apical residual space was observed in 3 patients in tented group. There was no morbidity in patients in tented group. CONCLUSION: Pleural tenting following upper lobectomy or bilobectomy of the lung shortens the duration of chest tube drainage and hospital stay, and it prevents apical residual air spaces and related complications. Pleural tenting is safe and relatively simple procedure, which has no associated morbidity.

Effect of needle tract bleeding on occurrence of pneumothorax after transthoracic needle biopsy.

PURPOSE: Occasionally bleeding along the needle trajectory is observed at post-biopsy computed tomographic sections. This study was designed to evaluate the possible effect of needle tract bleeding on the occurrence of pneumothorax and on requirement of chest tube insertion. MATERIALS AND METHODS: Two hundred eighty-four needle biopsies performed in 275 patients in whom the needle traversed the aerated lung parenchyma were retrospectively reviewed. Bleeding along the needle tract, occurrence of pneumothorax and need for chest tube insertion, type and size of the needle, size of the lesion, length of the lung traversed by the needle, presence or absence of emphysema were noted. Effect of these factors on the rate of pneumothorax and needle-tract bleeding was evaluated. The data were analyzed by chi2 test. RESULTS: Pneumothorax developed in 100 (35%) out of 284 procedures requiring chest tube placement in 16 (16%). Variables that were significantly associated with an increased risk of pneumothorax were depth of the lesion (P < 0.001) and severity of emphysema (P < 0.05). There was bleeding along the needle tract in 18.6% (n = 53) of the procedures. Pneumothorax occurred in 18 (33.9%) out of 53 procedures in which tract-bleeding was observed and in 82 (35.4%) out of 231 procedures in which tract-bleeding was not seen. The difference between the two groups was not significant (P > 0.05). However, analysis of the relation between length of lung traversed by the needle, tract-bleeding and pneumothorax rate indicated that tract-bleeding had a preventive effect on development of pneumothorax (P < 0.001). Occurrence of tract bleeding also had preventive effect on pneumothorax in the presence of emphysema (P < 0.05). The only variable which had effect on occurrence of tract-bleeding was the length of the lung traversed by needle (p < 0.001). Requirement for chest tube insertion was smaller in the tract-bleeding group than non-tract bleeding group, 11% (2/18) to 17% (14/82), respectively. But this difference was not significant statistically (P > 0.05). CONCLUSION: Bleeding in the needle tract has a preventive effect on the occurrence of the pneumothorax in deep-seated lesions and in the presence of emphysema, although it does not affect the overall rate of pneumothorax.

Management of postoperative chylothorax with nitric oxide: a case report.

OBJECTIVE: To describe the use of inhaled nitric oxide in the management of refractory postoperative chylothorax. DESIGN: Case report. SETTING: A pediatric intensive care unit of a tertiary care children's hospital. PATIENT: A neonate with refractory chylothoraces complicated by moderate pulmonary hypertension after a complicated arterial switch operation. INTERVENTIONS: Administration of inhaled nitric oxide through a ventilator circuit. MEASUREMENTS AND MAIN RESULTS: The institution of inhaled nitric oxide at 20 ppm resulted in a marked reduction in chest tube drainage and a decrease in echocardiographically estimated pulmonary artery pressure from 50%-75% systemic to 30%-50% systemic. Chest tube drainage doubled when the nitric oxide was decreased to 10 ppm and, again, dramatically decreased after raising nitric oxide back to 20 ppm. After 8 days of nitric oxide therapy, the chest tube drainage ceased. Nitric oxide therapy was successfully discontinued 19 days after initiation, with no recurrence of chylothorax. There was no effect of nitric oxide on systemic blood pressure. Methemoglobin levels while on NO remained <1.7%. CONCLUSION: Consideration may be given to the use of inhaled nitric oxide in the therapy of refractory chylothoraces complicated by central venous hypertension.

Small bore catheter drainage and sclerotherapy for malignant pleural effusions.

The accumulation of large amounts of fluid in the pleural space is a common sequela of disseminated carcinomatosis. Traditional management has included therapeutic thoracentesis or the placement of a large bore chest tube for drainage with the subsequent installation of a sclerosing agent in an attempt to achieve pleural symphysis. An evaluation of all patients treated in this manner during a 4-year period was undertaken to assess the degree of success obtained with a large bore standard chest tube versus a small pigtail catheter. A study group consisting of 20 patients with a total of 24 pleural effusions was treated with drainage and sclerotherapy. In this group, eight of 13 effusions were adequately treated with pigtail catheter drainage and sclerotherapy, compared with four of 11 effusions adequately treated with standard chest tube drainage and sclerotherapy. Although the numbers are small, it appears that pigtail catheter drainage and sclerosis is at least as successful as the more traditional drainage with the standard chest tube.

Thoracoscopy in the management of pediatric empyema.

The surgical management of empyema consists of (1) aggressive therapy with thoracotomy and decortication or (2) conservative treatment with chest tube drainage and intravenous antibiotics. Recently, Kern and Rodgers introduced thoracoscopic debridement as an adjunct to the management of children with empyema, with promising results. Hence, the authors report their experience with thoracoscopy in the management of pediatric patients with empyema. In the last years, 10 children have undergone thoracoscopic debridement (TD) for empyema. The average age was 6.9 years (range, 2 to 16). Children underwent TD an average of 14 days (range, 8 to 16) after initial presentation and 4 days (range, 2 to 6) after admission to the authors' hospital. Indications for TD were persistent requirement of supplemental oxygen and failure of conservative medical management that consisted of antibiotics and tube thoracostomy. Three children had positive pleural fluid cultures for Streptococcus pneumoniae. In all cases, preoperative ultrasound or chest computed tomography examination showed dense pleural fluid with septation. During surgery, TD allowed for lung expansion and precise chest tube placement in all patients except one who required conversion to minithoracotomy and decortication for persistent encasement with a thick pleural peel. There were no postoperative complications related to the procedure. After TD, all children had prompt clinical improvement. The patients were weaned from supplemental oxygen by postoperative day 2, and following early chest tube removal, nine children were discharged home by postoperative day 7 (range, 3 to 10). One child required further hospitalization for underlying renal failure. In the authors' hands, TD was effective in producing prompt clinical improvement in children with empyema.(ABSTRACT TRUNCATED AT 250 WORDS)

Management of pleural effusions in breast cancer.

Ninety-seven patients with breast cancer developed pleural effusions between January, 1971 and December, 1976. A retrospective analysis of 170 treatment procedures showed that 75 involved thoracocentesis alone, 23 involved thoracocentesis plus therapy with an alkylating agent, 22 involved drainage via a chest tube plus instillation of an alkylating agent, and 50 involved drainage via a chest tube plus instillation of tetracycline. The results are presented as censored survival curves. When management by chest tube plus instillation of an alkylating agent or tetracycline was compared with management by thoracocentesis plus therapy with an alkylating agent, analysis at six months after treatment showed that 42 percent (30/72) of the procedures left patients free of effusion using the former method, compared with 22 percent (5/23) of the procedures using the latter method. This is not quite significant at the 5 percent level using a summary chi2 procedure. The reasons for preferring tetracycline as a sclerosing agent are discussed.

Transaxillary minithoracotomy versus video-assisted thoracic surgery for spontaneous pneumothorax.

BACKGROUND: Although management of spontaneous pneumothorax by video-assisted thoracic surgery (VATS) has generally shown superior clinical results to thoracotomy, management of spontaneous pneumothorax by transaxillary minithoracotomy (TAMT) has also shown good clinical results. The objective of this study was to compare the clinical results of VATS and TAMT in treating spontaneous pneumothorax. METHODS: Sixty-six patients, aged 13 to 81 years, with recurrent, persistent or contralateral spontaneous pneumothorax were involved in this study. Thirty-six patients were treated by VATS and 30 by TAMT. The operating time, the amount of analgesics used on the first postoperative day, the duration of the indwelling chest tube, and the number of recurrences after operation were compared. The follow-up periods of both procedures were from 6 to 24 months. RESULTS: Of the 66 patients, 64 were male and 2 were female. The duration of operation, from start of skin incision to insertion of chest tube, was 91.2 +/- 36.8 minutes in VATS and 86.3 +/- 40.9 minutes in TAMT (p = 0.6061). The amount of analgesics (keptoprofen) used was 1.9 +/- 2.3 ampules in VATS and 2.1 +/- 2.9 ampules in TAMT (p = 0.0883). The duration of indwelling chest tube was 5.0 +/- 4.0 days in VATS and 4.3 +/- 2.1 days in TAMT (p = 0.3707). The number of recurrences after operation was 4 in VATS and none in TAMT. CONCLUSIONS: There were no advantages of VATS over TAMT for management of recurrent, persistent, or contralateral spontaneous pneumothorax in regard to the operating time, the amount of analgesics used on the first postoperative day, the duration of the indwelling chest tube, and the number of postoperative recurrences in patients with apical bullae.

Intrapleural heparin or heparin combined with human recombinant DNase is not effective in the treatment of empyema in a rabbit model.

OBJECTIVE AND BACKGROUND: The aim of this study was to investigate the effectiveness of intrapleural heparin or heparin combined with human recombinant DNase in the treatment of empyema. METHODS: Empyema was induced in rabbits with an intrapleural injection of 10(9)Pasteurella multicoda organisms in infusion agar via a surgically placed chest tube. Once empyema was verified, a blinded investigator administered drugs via the chest tube. There were three treatment groups each with six rabbits. One group was given 1000 IU heparin, a second group was given 1000 IU heparin plus 1 mg of human recombinant DNase via chest tube and the control group received saline. The rabbits received treatment every 12 h for a total of six treatments and the volume of each treatment was 3 mL. The animals were sacrificed at day 10 and the amount of empyema and pleural thickening was scored macroscopically on a scale of 0-6. RESULTS: The total volume of pleural effusion aspirated was significantly higher in the heparin group (25.8+/-10.7 mL) compared with either saline (8+/-8.9) or heparin plus human recombinant DNase (6.8+/-6.1) groups (P=0.003). The mean empyema and pleural thickening scores did not differ significantly between the groups (P=0.8, P=0.5 respectively). A weak correlation was found between total volume of aspirated pleural fluid and pleural parameters of white blood cell counts and LDH levels (r=0.546 and P=0.02, r=0.631 and P=0.02 respectively). CONCLUSION: The intrapleural administration of 1000 IU heparin alone or in combination with 1 mg of human recombinant DNase is no more effective than saline in the treatment of empyema in rabbits. Intrapleural heparin significantly increased the drainage of pleural fluid compared with the combination and saline group.

VATS increases costs in patients undergoing lung biopsy for interstitial lung disease.

Proliferation in the use of video-assisted thoracic surgery (VATS) has occurred without data demonstrating benefit. Few studies have critically compared VATS with limited thoracotomy (LT) in homogeneous patient populations undergoing standardized procedures. We retrospectively reviewed the hospital records of 37 consecutive patients referred for elective lung biopsy as part of an ongoing interstitial lung disease protocol to determine whether VATS improved outcome or reduced costs. Sixteen patients underwent VATS, and 21 patients underwent LT lung biopsy over a 31 month period. The two groups were homogeneous in regard to clinical symptoms, radiologic findings, age, sex, and preoperative pulmonary function. The operative mortality was not different between the two groups (VATS, 0/16, and LT, 1/21). The postoperative stay was 4.8 +/- 1.0 days for VATS and 5.0 +/- 0.5 days for LT (p = not significant). Operating time, number of specimens obtained, chest tube output, and day of chest tube removal did not differ. There was no difference in the amount of analgesics required during the postoperative period. Operating room cost for VATS was significantly greater than that for LT ($2,663 +/- $384 versus $1,801 +/- $94; p = 0.04) despite the use of nondisposable equipment. Anesthesia-related costs were also greater for VATS ($309 +/- $11 versus $244 +/- $15; p = 0.002). In conclusion, lung biopsy in patients with interstitial lung disease can be performed safely and efficiently with either VATS or LT, but VATS results in higher procedure-related costs.

Empyema management: twelve years' experience since the introduction of video-assisted thoracoscopic surgery.

We reviewed empyema management at our center since video-assisted thoracoscopic surgery (VATS) was introduced. Between 1991 and 2003, 58 patients (34 male, 24 female) ages 1 day to 17 years (median, 6 years) were identified. The median interval from the onset of symptoms to presentation was 7 days; 31% of patients received inpatient care at another hospital, and 24% were from northern communities, including the Arctic. Symptoms included fever (100%), cough (66%), shortness of breath (46%), chest pain (38%), and abdominal pain (17%). Most patients (96%) had pneumonia. The most common organisms were Streptococcus pneumoniae (22%), group A streptococcus (8%), and Mycobacterium tuberculosis (3%). No organisms were identified in 31% of patients. One empyema was trauma-related and one was due to complications of esophageal stricturoplasty. All patients received intravenous antibiotics (median, 17 days). Three patients had thoracentesis, 17 had chest tubes, 3 had thoracentesis and chest tubes, 26 had VATS, 6 had thoracotomy, and 3 had minithoracotomy. Median operative times were 86 minutes for VATS, 90 minutes for thoracotomy, and 75 minutes for minithoracotomy. Median total length of stay (LOS) was 15 days for VATS, 20.5 days for thoracotomy, and 21 days for minithoracotomy. The median preoperative LOS was longer for thoracotomy (10 days) than for VATS (5 days) or minithoracotomy (1 day). The median postoperative LOS was 14 days for VATS, 9.5 days for thoracotomy, and 8 days for minithoracotomy. Our experience shows that VATS is a safe and effective approach to managing children with empyema. The shorter preoperative LOS for VATS is likely due to earlier surgical referral and intervention using less invasive surgical procedures.
