A prospective comparison of supine chest radiography and bedside ultrasound for the diagnosis of traumatic pneumothorax.

BACKGROUND: Supine anteroposterior (AP) chest radiography may not detect the presence of a small or medium pneumothorax (PTX) in trauma patients. OBJECTIVES: To compare the sensitivity and specificity of bedside ultrasound (US) in the emergency department (ED) with supine portable AP chest radiography for the detection of PTX in trauma patients, and to determine whether US can grade the size of the PTX. METHODS: This was a prospective, single-blinded study with convenience sampling, based on researcher availability, of blunt trauma patients at a Level 1 trauma center with an annual census of 75,000 patients. Enrollment criteria were adult trauma patients receiving computed tomography (CT) of the abdomen and pelvis (which includes lung windows at the authors' institution). Patients in whom the examination could not be completed were excluded. During the initial evaluation, attending emergency physicians performed bedside trauma US examinations to determine the presence of a sliding lung sign to rule out PTX. Portable, supine AP chest radiographs were evaluated by an attending trauma physician, blinded to the results of the thoracic US. The CT results (used as the criterion standard), or air release on chest tube placement, were compared with US and chest radiograph findings. Sensitivities and specificities with 95% confidence intervals (95% CIs) were calculated for US and AP chest radiography for the detection of PTX, and Spearman's rank correlation was used to evaluate for the ability of US to predict the size of the PTX on CT. RESULTS: A total of 176 patients were enrolled in the study over an eight-month period. Twelve patients had a chest tube placed prior to CT. Pneumothorax was detected in 53 (30%) patients by US, and 40 (23%) by chest radiography. There were 53 (30%) true positives by CT or on chest tube placement. The sensitivity for chest radiography was 75.5% (95% CI = 61.7% to 86.2%) and the specificity was 100% (95% CI = 97.1% to 100%). The sensitivity for US was 98.1% (95% CI = 89.9% to 99.9%) and the specificity was 99.2% (95% CI = 95.6% to 99.9%). The positive likelihood ratio for a PTX was 121. Spearman's rank correlation showed at rho of 0.82. CONCLUSIONS: With CT as the criterion standard, US is more sensitive than flat AP chest radiography in the diagnosis of traumatic PTX. Furthermore, US allowed sonologists to differentiate between small, medium, and large PTXs with good agreement with CT results.

The performance of four pleural drainage systems in an animal model of bronchopleural fistula.

In order to compare the performance of four pleural drainage units (PDU [Emerson Post-Operative Pump, Pleur-Evac, Sentinel Seal, Thora-Klex]), we created an animal model of bronchopleural fistula that simulated the type of air leak seen clinically (mean maximal flow = 5 L/min). The PDU were tested at 0 cm (water seal), -20 cm and -40 cmH2O suction. Compared to water seal, -20 cmH2O suction significantly increased the ability of all four PDU to evacuate air via the chest tube and abolished small differences in chest tube air leak seen among the PDU at water seal. An increase in suction to -40 cmH2O did not significantly alter flow via the chest tube. Previously demonstrated differences among the PDU in handling large air flows were not seen in this lower flow model of bronchopleural fistula. However, because of their higher resistance, use of the Sentinel Seal and of the Thora-Klex was technically impractical even at air leaks of 4 to 5 L/min.

Mediastinal chest drain clearance for cardiac surgery.

BACKGROUND: Cardiac tamponade may occur following cardiac surgery as a result of blood or fluid collecting in the pericardial space compressing the heart and reducing cardiac output. Mediastinal chest drains (including pericardial drains) are inserted as standard post-operative practice following cardiac surgery to assist the clearance of blood from the pericardial space and to prevent cardiac tamponade. To prevent chest tubes from blocking and so causing tamponade nurses manipulate them to prevent or remove clots. Manipulation methods including milking, stripping, fanfolding and tapping may be applied to the tubes to keep them from blocking. Evidence is required as to the safest and most effective means of preventing chest tube blockage and preventing cardiac tamponade. OBJECTIVES: To compare different methods of chest drain clearance (i.e. varying levels of suction or suction in combination with milking, stripping, fanfolding and tapping of chest drains) in preventing cardiac tamponade in patients following cardiac surgery. SEARCH STRATEGY: Over both the initial review and the 2004 revision, we searched the Cochrane Heart Group trials register, the Cochrane Controlled Trials Register (CCTR) (Issue 4, 2003) The Cochrane Database of Systematic Reviews (CDSR), the Database of Abstracts of Reviews of Effectiveness (DARE), Issue 4, 2003, MEDLINE (1966 to Nov Week 2, 2003), EMBASE (1980 to 2003 Week 47), CINAHL (1982 to Nov 2003), the Clinical Trials site of the NIH, (USA) (24.11.03) and reference lists of articles. SELECTION CRITERIA: Randomised, quasi-randomised or systematically allocated clinical trials of chest tube manipulation methods in adults and children with mediastinal chest drains following cardiac surgery were included. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed trial quality and extracted data. Study authors were contacted for additional information where required. Adverse effects information was collected from the trials. MAIN RESULTS: Three studies with a total of 471 participants were included. There was no data, however, which could be included in a meta-analysis. This was due to inadequate data provision by two of the studies. Where adequate data were provided there were no common interventions or outcomes to pool. On the basis of single studies there was no evidence of a difference between groups on incidence of chest tube blockage, heart rate, cardiac tamponade or incidence of surgical re-entry. REVIEWERS' CONCLUSIONS: There are insufficient studies which compare differing methods of chest drain clearance to support or refute the relative efficacy of the various methods in preventing cardiac tamponade. Nor can the need to manipulate chest drains be supported or refuted by results from RCT's.

A prospective evaluation of video-assisted thoracic surgery for persistent air leak due to trauma.

BACKGROUND: The time required for air leak resolution after chest trauma is not well described. Based on an institutional review of posttraumatic air leaks our hypothesis was that video-assisted thoracic surgery (VATS) for persistent posttraumatic air leak would decrease chest tube days and length of stay compared with nonoperative management. METHODS: Patients were offered VATS versus nonoperative management when air leaks persisted longer than 3 days and the patients were otherwise ready for discharge. Chest tube days and length of stay were recorded. RESULTS: Of 223 trauma patients requiring chest tubes, 50 had persistent air leaks, 39 of whom were otherwise ready for discharge. Twenty-five chose VATS and 14 nonoperative (NOP) treatment. The mean chest tube days was 8.1 for VATS versus 11.8 for NOP (P = 0.001). Mean length of stay was 9.7 days for VATS and 16.5 days for NOP (P = 0.002). CONCLUSIONS: In patients otherwise ready for discharge VATS reduces chest tube days and length of stay when used to treat persistent posttraumatic air leak.

Intrapleural alteplase in a patient with complicated pleural effusion.

OBJECTIVE: To report the intrapleural use of alteplase in a patient diagnosed with complicated pleural effusion (CPE). CASE SUMMARY: A 62-year-old white woman admitted with respiratory distress and hypotension developed a right-sided multi-loculated pleural effusion. Thoracentesis and chest tube drainage were not successful in resolving the effusion. In an attempt to increase the drainage of the pleural effusion, alteplase 16 mg was administered into the pleural cavity via the chest tube on 6 consecutive days. As a result, the volume drained from the patient's chest tube increased, there was improvement on the chest X-ray, and she did not require surgical intervention. DISCUSSION: While streptokinase and urokinase have been shown to be useful adjuncts to chest tube drainage in the treatment of complicated pleural effusion and empyema, there have been no reports on the use of intrapleural alteplase. This report demonstrates that intrapleural administration of alteplase is a useful adjunct to tube drainage in resolving CPE. CONCLUSIONS: This patient's CPE resolved when intrapleural alteplase was used as an adjunct to chest tube drainage and antibiotics. Controlled trials need to be conducted to investigate fully the efficacy, dosing, and safety of intrapleural alteplase in the treatment of patients with CPE and empyema.

[Neonatal pneumothorax].

INTRODUCTION: Neonatal pneumothorax (NP) is associated with an increased mortality. However, few studies have evaluated which parameters are associated with neonatal death and infant death. METHODS: Retrospective study of newborns treated for NP at a university hospital in the period 1.1.1989 to 31.12.1998. RESULTS: Forty-seven newborns (30 boys, 17 girls) had NP. Thirty-two infants (68%) had chest tube insertion, and 15 (32%) did not need chest tube. Nine infants (19%) died within one week after birth. Six of these were mature infants with additional major congenital malformations. The remaining three were premature infants with gestational ages of 25, 26 and 29 weeks, respectively. Another 29 week old infant died during the first year of life, bringing the total number of deaths within one year to ten (21%). No deaths occurred among infants with NP who did not have chest tube insertion. Apart from the presence of additional major congenital malformations (p = 0.001/0.003) and the need for mechanical ventilation after tube insertion (p = 0.058/0.035) none of the selected parameters (sex, birth weight, gestational age, way of delivery, CPAP treatment before tube insertion, mechanical ventilation before tube insertion, uni or bilateral pneumothorax, and total number of tubes) had significant relationship to neonatal death or infant death. DISCUSSION: The presence of additional congenital malformations and the need for mechanical ventilation after tube insertion were the only parameters in this series which were associated with an increased mortality in infants with NP demanding tube drainage.

[The value of subjective estimation of the severity of thoracic injuries by the emergency surgeon].

INTENTION: Thorax trauma (TT) is associated with a high rate of pulmonary failure and increased mortality. To prevent these complications, the German trauma system recommends intubation and chest tube insertion at the scene of the accident, even in cases without acute respiratory dysfunction. Due to the possible life threatening complications of the therapy, the emergency surgeon should be able to correctly identify a TT at the scene. Therefore, we retrospectively compared the evaluation of chest trauma by the emergency surgeon with objective injury severity according to the Abbreviated Injury Scale (AIS). METHOD: Data from 2,392 patients (aged 39+/-1 years, Injury Severity Score 27+/-0.3) were taken from the multiple trauma database of the German Trauma Society. The evaluation of TT (absent, light, medium, severe) by the emergency surgeon was compared with objective injury severity (AIS=0: absent, 0>AIS<3: light, AIS=3: medium, AIS>3: severe). If the difference between the subjective and objective injury severity increased or decreased two and more levels, a substantial misclassification was assumed. The influence of the estimate on outcome was tested by comparing the predicted (TRISS-method) with the observed fatalities. RESULTS: Absence of TT was estimated correctly in 62%, light in 24%, medium in 40% and severe TT in 46% of cases. Thus a correct estimate of TT was made for 49% of the patients. The chest injury severity was substantially overrated by the emergency surgeon in 20% and substantially underestimated in 17% of cases. In patients with the correct classification at the scene, a total of 81% received a chest tube. Of these patients, only 50% received their chest tube at the scene. Of the patients with an initially overlooked TT, only 37% received a chest tube and nearly all were placed in the emergency room. The number of fatalities was lower than predicted in all groups, even in patients with correctly estimated severe TT (observed: 34%, estimated: 42+/-2%), and also in patients with initially overlooked TT (observed: 16%, estimated: 24+/-2%). CONCLUSION: Due to the high rate of misclassification and possible severe complications caused by therapy, and without having any benefit in terms of outcome, intubation and chest tube insertion should not be carried out in vital, stable patients.

Intrapleural streptokinase in a two-year-old child with a parapneumonic effusion.

A two-year-old child was hospitalised with features of parapneumonic effusion. He was initially managed with parenteral antibiotics and chest tube drainage. After three days drainage became insignificant inspite of chest tube being patent and appropriately positioned. CT scan of chest showed multiloculated effusion. In view of multiloculated effusion it was decided to try intrapleural fibrinolysis with streptokinase. Streptokinase in a dose of 1,25000 IU dissolved in 50 ml of normal saline was instilled through the chest tube daily. After instilling three doses, there was a significant increase in the drainage followed by almost complete radiological resolution. There were no side effects. Intrapleural streptokinase is a useful adjunctive threapeutic modality in the management of complicated parapneumonic effusion or empyema in paediatric patients.

Aspiration of a large pneumothorax resulting from transthoracic needle biopsy.

PURPOSE: To determine whether simple aspiration of air from the pleural space could obviate chest tube placement in patients with a large pneumothorax after transthoracic needle biopsy. MATERIALS AND METHODS: Seventeen patients, who developed a large pneumothorax (> 30%) during computed tomographic (CT)-guided transthoracic needle biopsy and otherwise would have required chest tube placement, underwent percutaneous aspiration of the pneumothorax while on the CT scanner table. Air was aspirated from the pleural space by using an 18-gauge intravenous catheter attached to a three-way stopcock and a 50-mL syringe. The patients were positioned with the puncture site down after aspiration of the pneumothoraces and oxygen was administered both during and after the procedure. RESULTS: The pneumothorax was almost completely aspirated in all 17 patients. Twelve (70%) patients did not require chest tube placement. Follow-up chest radiographs obtained 2 and 4 hours after the procedure revealed complete or almost complete resolution of the pneumothorax in eight (47%) patients and partial recurrence of a small, stable pneumothorax in four (24%) patients. The remaining five (29%) patients had recurrence of their pneumothorax, which ultimately required chest tube placement. CONCLUSION: Percutaneous catheter aspiration of a large biopsy-induced pneumothorax is safe and easy to perform and may obviate chest tube placement.

CT-guided transthoracic needle aspiration biopsy of small (< or = 20 mm) solitary pulmonary nodules.

OBJECTIVE: The purpose of our study was to determine the diagnostic accuracy and to analyze the factors influencing the diagnostic accuracy and incidences of pneumothorax and chest tube insertion rates for percutaneous CT-guided needle biopsy of small (< or = 20 mm) solitary pulmonary nodules. SUBJECTS AND METHODS: One hundred sixty-two patients with 162 small solitary pulmonary nodules underwent CT-guided transthoracic needle aspiration biopsy. The overall diagnostic accuracy, pneumothorax rate, and chest tube insertion rate were calculated. Factors influencing the diagnostic accuracy and pneumothorax rate were statistically evaluated. Influencing factors, diagnostic accuracies, pneumothorax rates, and chest tube insertion rates were statistically compared. RESULTS: Overall diagnostic accuracy, pneumothorax rate, and chest tube insertion rate were 77.2%, 28.4%, and 2.5%, respectively. Diagnostic accuracy was significantly affected by length of needle path and lesion size (p < 0.05). The pneumothorax rate was significantly affected by the percentage of predicted forced expiratory volume in 1 sec, the number of punctures, and the needle path length (p < 0.05). The chest tube insertion rate was significantly affected by the number of punctures (p < 0.05). For diagnostic accuracy, needle path lengths of 40 mm or less and lesion sizes greater than 10 mm were significantly more accurate than other factors (p < 0.05). For pneumothorax rates, a percentage of predicted forced expiratory volume in 1 sec of greater than 70%, a single puncture, and a needle path length of 40 mm or less were significantly lower than other factors (p < 0.05). CONCLUSION: CT-guided transthoracic needle aspiration biopsy is a useful diagnostic tool for small solitary pulmonary nodules smaller than 20 mm in diameter. The diagnostic accuracy is significantly improved for large (> 10 mm) lesion size and short (< or = 40 mm) needle path length.

Percutaneous transthoracic needle biopsy of the lung: review of 612 lesions.

PURPOSE: The results and complications of 651 pulmonary fine-needle aspiration biopsies (FNABs) were reviewed. The number of needle passes and needle size were correlated to pneumothorax and chest tube placement rates. MATERIALS AND METHODS: FNAB of the lung was performed on 651 occasions in 612 patients with 18- to 22-gauge Franseen needles. Diagnostic rates were calculated. The number of needle passes performed and needle size used were evaluated for their association with pneumothorax and subsequent chest tube placement. RESULTS: Diagnostic accuracy was 94% with sensitivity for malignancy of 95%. Positive and negative predictive values were 99.5% and 90%, respectively. Pneumothorax occurred in 26.9% of patients with 9.2% requiring chest tube placement. Increasing numbers of needle passes and larger needle sizes did not increase the rates of pneumothorax or chest tube placement. CONCLUSIONS: FNAB of the lung has excellent diagnostic rates and remains the procedure of choice for diagnosing pulmonary lesions. This large study contradicts perceptions that pneumothorax and chest tube placement rates decrease with thinner needles and fewer passes.

Pneumothorax.

Spontaneous pneumothoraces can occur without obvious underlying lung disease (primary) or in patients with known underlying lung disease (secondary). Management guidelines for spontaneous pneumothorax have been published by major professional organizations, but awareness and application among clinicians seems poor. First episodes of primary spontaneous pneumothorax can be managed with observation if the pneumothorax is small. If the pneumothorax is large or if the patient is symptomatic, manual aspiration via a small catheter or insertion of a small-bore catheter coupled to a Heimlich valve or water-seal device, should be performed. In general, definitive measures to prevent recurrence are recommended after the first recurrence of the pneumothorax, and can be achieved by medical (e.g. talc) or surgical (video-assisted thoracic surgery) pleurodesis. Secondary pneumothoraces should be treated with chest tube drainage followed by pleurodesis after the first episode to minimize any risk of recurrence. Traumatic pneumothoraces may be occult (not seen on an initial CXR) or non-occult. The majority are treated by placement of a chest tube. Selected patients may be treated conservatively, with approximately 10% of these patients eventually requiring chest tube placement. Iatrogenic pneumothoraces have a myriad of causes with transthoracic lung needle biopsy being most common. Transthoracic needle biopsy-related pneumothoraces have CT findings that can predict their occurrence and the need for chest tube placement. Iatrogenic pneumothoraces, regardless of cause, may be managed by observation or small bore chest tube placement, depending upon patient stability and the size of the pneumothorax.

The surgical management of empyema thoracis in substance abuse patients: a 5-year experience.

Postpneumonic empyema (EMP) may develop in substance abuse patients, requiring prolonged hospitalization. An algorithm that provides quality care and a rational basis for timely surgical intervention would be advantageous. We report our five-year experience with EMP in substance abuse patients and present such a treatment plan. Sixty-one substance abuse patients were treated for EMP. Posteroanterior, lateral, and decubitus x-ray studies were obtained before treatment to assess fluid movement. Chest tubes were placed to drain frank pus and to obtain material for positive smears. X-ray studies and computed tomography were done 24 hours later to assess parenchymal pathology and to detect any multiple loculations. Thirty-three substance abuse patients recovered following initial tube thoracostomy and 7 after a second chest tube was introduced. Twenty-one had multiple loculations and underwent thoracotomy. Twenty of the 21 required extensive debridement or decortication, or both; 2 required lobectomy and 1 pneumonectomy. Chest tubes were removed on an average of 6 +/- 1.5 days. Average postoperative stay was 10.7 +/- 2 days. There were 2 early deaths and 1 late death and no recurrent EMP. Bacteriology findings were nonspecific and often polymicrobial. We conclude that early thoracotomy can be lifesaving in the presence of a benign clinical course.

Pleurodesis by autologous blood, doxycycline, and talc in a rabbit model.

BACKGROUND: Management of recurrent spontaneous pneumothorax or symptomatic pleural effusion often uses thoracoscopic pleurodesis, about which many questions remain. Both effectiveness and toxicity of agents currently used for pleurodesis were evaluated in a rabbit model. METHODS: Agents administered were autologous blood 1 mL/kg, talc slurry (70 mg x mL(-1) x kg(-1)), and doxycycline 10 mg/mL, given through a chest tube to 30 rabbits. Controls had only chest tubes inserted. At 30 days surfaces were graded by gross observation and histologic examination. Blood and lung tissue from all animals were analyzed for enzymes and blood chemistries. RESULTS: Gross observations showed mediastinal thickening and adhesions with doxycycline, and threadlike adhesions with talc. Autologous blood was only slightly more effective than a chest tube alone. Talc significantly increased angiotensin converting enzyme activity in serum, whereas doxycycline changed liver function enzymes and produced tissue toxicity. CONCLUSIONS: Doxycycline produced effective pleurodesis but yielded remarkably severe local effects. The distant sequelae of talc and doxycycline pleurodesis-histologic changes in the contralateral lung and serum enzyme elevations-suggests undesirable systemic effects for the commonly used agents, and autologous blood exhibited no significant pleurodesis, short-term. The search for the ideal agent for chemical pleurodesis continues.

Relationship between factor XIII activity, fibrinogen, haemostasis screening tests and postoperative bleeding in cardiopulmonary bypass surgery.

We investigated the relationship between factor XIII, fibrinogen, blood coagulation screening tests and postoperative bleeding in 98 patients undergoing cardiopulmonary bypass (CPB) surgery. All patients received aprotinin. Blood samples were collected preoperatively (T1),after termination of CPB (T2),12 h (T3) and 24 h (T4) after surgery to determine FXIII activity, fibrinogen, platelet count, prothrombin time (PT), activated partial thromboplastin time (APTT) and D-dimers (DD). Laboratory results were correlated with the chest tube drainage 24 h after surgery and compared between patients with 24-hour chest tube drain volumes in the lower (Group 1) with those in the upper tertile (Group 3). Median FXIII and fibrinogen levels dropped by 33.9% and 34.2%, respectively, during CPB. No association between FXIII activity and the extent of postoperative bleeding was found. However, chest tube bleeding was significantly correlated with preoperative and postoperative fibrinogen. This was confirmed by comparing Groups 1 and 3. Group 3 patients had significantly lower fibrinogen levels than Group 1 at T1 - T4, although most fibrinogen values were within or above the reference range (medians, g/l: 3.5 vs. 4.0, p = 0.043 at T1; 2.3 vs. 2.7, p = 0.015 at T2; 2.9 vs. 3.3, p = 0.008 at T3; 4.2 vs. 5.2, p = 0.002 at T4). There was also a significant relationship of platelet count, PT and APTT, as measured after CPB (T2), with postoperative chest tube drainage. In conclusion, plasma FXIII activity does not influence postoperative bleeding in patients undergoing CPB surgery. There is however an inverse association between preoperative or postoperative plasma fibrinogen levels and postoperative bleeding. These findings indicate a modulation of postoperative bleeding by fibrinogen levels.

Management of patients with "ex vacuo" pneumothorax after thoracentesis.

RATIONALE AND OBJECTIVES: To determine clinical outcome in patients who developed "ex vacuo" pneumothorax following thoracentesis and to assess the benefit of chest tube placement for this complication. MATERIALS AND METHODS: We retrospectively reviewed records of 282 patients who underwent 437 thoracenteses at a single institution during a 6-year period. We identified 34 patients (12.1%) who developed a pneumothorax following 39 thoracenteses (8.8%) and then identified a subset of patients with pneumothorax "ex vacuo" defined as a moderate to large hydropneumothorax or small pneumothorax persisting for more than 3 days. Patient charts were reviewed to document the treatment strategy employed and subsequent clinical outcome, which included length of hospital stay, resolution of pneumothorax, reaccumulation of pleural effusion, and overall survival. RESULTS: Ten patients developed "ex vacuo" pneumothroax following thoracentesis. None complained of significant worsening of symptoms following thoracentesis. Seven patients were treated by observation alone and 3 patients underwent tube thorocostomy. A decrease in size of the pneumothorax was observed in only 3 patients, none of whom had a chest tube placed. Effusion completely reaccumulated in 7 patients. All 10 patients died during the follow-up period; the mean survival was 157 days (range: 13-402 days). Survival among patients treated by observation was 191.4 days versus 71.7 days for patients receiving chest tubes. CONCLUSION: Life expectancy for most patients who develop "ex vacuo" pneumothorax following therapeutic thoracentesis is short (<6 months). Chest tube placement is not necessary in asymptomatic patients and is unlikely to provide clinical benefit.

Single-stage complete muscle flap closure of the postpneumonectomy empyema space: a new method and possible solution to a disturbing complication.

The management of postpneumonectomy empyema remains a disturbing and controversial area in the field of thoracic surgery. Many methods have been described and have had varying degrees of success. We present a series of 5 consecutive patients who underwent single-stage complete muscle flap closure of the pneumonectomy space with extrathoracic muscle flaps and omental grafts between October, 1981, and April, 1983. Two men and three women ranging from 37 years to 64 years old underwent such a closure from 3 to 13 months after original resection. Two patients had associated bronchopleural fistula. Prior to closure, 3 patients were managed with chest tubes and 2 with a modified Eloesser procedure. All operations were single-stage procedures, and all wounds closed primarily, with no permanent tubes or chest wall openings. There was no morbidity or mortality, and no subsequent operation has been required. Single-stage complete muscle flap closure of the postpneumonectomy empyema space has not been described previously, and we think it offers a possible solution to this potentially fatal complication.

Selective management of iatrogenic esophageal perforation in the newborn.

Since 1974 nine neonates have been treated for iatrogenic esophageal perforation. They ranged in weight from 480 to 3900 g. Four of them had been resuscitated for meconium aspiration, four were being treated for respiratory distress syndrome (RDS), and one had received only routine postpartum suctioning and gastric aspiration. In five infants, esophageal perforation was suspected following traumatic intubation of difficulty in the passage of a catheter or tube. Three neonates passed formula from chest tubes placed for pneumothorax and one child presented with persistent pneumothorax. Esophageal perforation was documented in each case by direct visualization and/or radiographic studies. Three infants were treated with antibiotics and placement of a silastic nasogastric feeding tube. An additional two infants were treated with a silastic tube, antibiotics and chest tube drainage. Four children underwent operation: gastrostomy and drainage (2), gastrostomy and closure of perforation (1), gastrostomy only (1). There were no complications of deaths. Management of iatrogenic perforation of the esophagus depends upon the extent and location of the injury. A nonoperative approach can be successful in those infants with limited injury of short duration. Operation is required in cases with extensive extravasation or delay in diagnosis.
