Thoracoscopic decortication vs tube thoracostomy with fibrinolysis for empyema in children: a prospective, randomized trial

Purpose

Management of empyema has been debated in the literature for decades. Although both primary video-assisted thoracoscopic surgery (VATS) and tube thoracostomy with pleural instillation of fibrinolytics have been shown to result in early resolution when compared to tube thoracostomy alone, there is a lack of comparative data between these modes of management. Therefore, we conducted a prospective, randomized trial comparing VATS to fibrinolytic therapy in children with empyema.

Methods

After Institutional Review Board approval, children defined as having empyema by either loculation on imaging or more than 10,000 white blood cells/μL were treated with VATS or fibrinolysis. Based on our retrospective data using length of postoperative hospitalization as the primary end point, a sample size of 36 patients was calculated for an α of .5 and a power of 0.8. Fibrinolysis consisted of inserting a 12F chest tube followed by infusion of 4 mg tissue plasminogen activator mixed with 40 mL of normal saline at the time of tube placement followed by 2 subsequent doses 24 hours apart.

Results

At diagnosis, there were no differences between groups in age, weight, degree of oxygen support, white blood cell count, or days of symptoms. The outcome data showed no difference in days of hospitalization after intervention, days of oxygen requirement, days until afebrile, or analgesic requirements. Video-assisted thoracoscopic surgery was associated with significantly higher charges. Three patients (16.6%) in the fibrinolysis group subsequently required VATS for definitive therapy. Two patients in the VATS group required ventilator support after therapy, one of whom required temporary dialysis. No patient in the fibrinolysis group clinically worsened after initiation of therapy.

Conclusions

There are no therapeutic or recovery advantages between VATS and fibrinolysis for the treatment of empyema; however, VATS resulted in significantly greater charges. Fibrinolysis may pose less risk of acute clinical deterioration and should be the first-line therapy for children with empyema.     

Evolving experience with video-assisted thoracic surgery in congenital cystic lung lesions in a British pediatric center

Background/Purpose

Video-assisted thoracic surgery (VATS) is increasingly used for the resection of congenital cystic lung lesions (CLLs). This study aimed to evaluate the efficacy of VATS and its outcome in both antenatally and postnatally detected CLLs.

Methods

Forty-six patients managed during 2000-2005 were studied. Demographics, investigations, operative details, and outcome data were collected and evaluated. Patients were divided into 3 groups for analysis.

Results

Antenatally diagnosed (groups I and II, n = 35): group I (20) had VATS at 20 months median (range, 16-35 months). Video-assisted thoracic surgery was successful in 14 of 20 (70%), notably in all cases of extralobar sequestrations and foregut duplication cysts. Inadequate vision/lung collapse and technical difficulties were the main reasons for conversion to open thoracotomy. Group II (n = 15) was considered unsuitable for VATS because of neonatal symptoms (6 congenital cystic adenomatoid malformations of the lung [CCAMs]) and/or large size/inexperience (5 CCAMs, 4 sequestrations) and had elective thoracotomy at 8 months median (range, 6 days-20 months).Postnatally diagnosed (group III, n = 11): 3 CCAMs, 6 duplications, and 2 sequestrations were diagnosed because of recurrent chest infection (8) or stridor (2), or incidentally (1) at 8 years median (range, 1.2-14 years). Video-assisted thoracic surgery was successful in 3 foregut duplications. A duplication and an intralobar sequestration were converted; open thoracotomy was performed in others because of previous recurrent pneumonic episodes.Postoperative pain and hospital stay were significantly less (P < .001) in successful VATS resection: median of 2 days (range, 1-7 days) compared with thoracotomy median of 6 days (range, 4-20 days).

Conclusions

Video-assisted thoracic surgery is a safe and effective option for asymptomatic congenital CLLs. It is anticipated that more successful CCAM resections using VATS will occur in the future as our technical ability improves.     

Efficacy of video-assisted thoracoscopic surgery in managing childhood empyema: a large single-centre study

Background/Purpose

A randomised controlled trial evaluating the role of video-assisted thoracoscopic surgery (VATS) in childhood empyema reported a failure rate of 16.6%. Our aim is to determine the outcome of VATS in a large series of children managed by 3 paediatric surgeons experienced in endoscopic surgery.

Method

A retrospective study of all children with empyema admitted under the care of the 3 surgeons between February 2004 and February 2008 was undertaken. Recorded details included demographic data, mode of presentation, preoperative investigations, operative details, antibiotic usage, microbiological data, postoperative course, follow-up data and complications.

Results

114 children (69 boys, 45 girls) had VATS for empyema. Their median age was 5 (0.2-15) years. The pleural cavity was drained for a median of 4 (2-13) days. Median postoperative hospital stay was 7 (4-36) days. Median follow-up was 8 (1-24) months. There were 8 (7%) treatment failures: 5 conversions to thoracotomy and 3 recurrent empyemas. There were 7 complications (6%): air leak (n = 6) and lung injury (n = 1). 104 (91%) children had full resolution of symptoms. There were no deaths.

Conclusion

Video-assisted thoracoscopic surgery has a better outcome in childhood empyema than reported in a recent randomised trial and it has an important role in the management of this condition.     

First decade's experience with thoracoscopic lobectomy in infants and children

Purpose

This study evaluates the safety and efficacy of thoracoscopic lobectomy in infants and children.

Methods

From January 1995 to March 2007, 97 patients underwent video-assisted thoracoscopic lobe resection. Ages ranged from 2 days to 18 years and weights from 2.8 to 78 kg. Preoperative diagnosis included sequestration/congenital adenomatoid malformation (65), severe bronchiectasis (21), congenital lobar emphysema (9), and malignancy (2).

Results

Of 97 procedures, 93 were completed thoracoscopically. Operative times ranged from 35 minutes to 210 minutes (average, 115 minutes). There were 19 upper, 11 middle, and 67 lower lobe resections. There were 3 intraoperative complications (3.1%) requiring conversion to an open thoracotomy. Chest tubes were left in 88 of 97 procedures for 1 to 3 days (average, 2.1 days). Hospital stay ranged from 1 to 12 days (average, 2.4 days).

Conclusions

Thoracoscopic lung resection is a safe and efficacious technique. It avoids the inherent morbidity of a major thoracotomy incision and is associated with the same decrease in postoperative pain, recovery, and hospital stay as seen in minimally invasive procedures.     

Video-assisted thoracoscopic versus open surgery for persistent ductus arteriosus

Background/Purpose

The aim of this study is to compare the experience with video-assisted thoracoscopic surgery (VATS) for patent ductus arteriosus (PDA) since 1995 with the results of conventional open surgery from the preceding 10 years.

Methods

The records of 60 children who underwent standard posterolateral muscle splitting thoracotomy and ligation of PDA in 1986-1995 were reviewed for the study. The data on 50 children who underwent VATS PDA ligation since 1995 were collected prospectively.

Results

All patients survived. Ductal bleeding requiring sutures with patches occurred once in the open surgery group. Two patients in the VATS group underwent immediate rethoracoscopy and clipping because of residual ductal flow in the postoperative echocardiography. Complications in the VATS group included 6 (12%) recurrent laryngeal nerve injuries (3 transient) and 2 chylothoraces. One patient in each group underwent open reoperation because of residual ductal flow 1 year after the initial operation. The operative time, duration of recovery room/neonatal intensive care unit care, duration of pleural drainage, and length of hospital stay were significantly shorter in the VATS group.

Conclusions

VATS PDA ligation gave results equal to traditional open surgery with a shorter operative time, faster recovery, and shorter hospital stay. More complications, especially recurrent laryngeal nerve injuries, occurred in the VATS group.     

Video-assisted thoracoscopic surgical excision of cystic lung disease in children

Purpose

Video-assisted thoracoscopic surgical (VATS) technique for resection of cystic lung disease (CLD) may offer some advantages when compared with thoracotomy in children.

Methods

From September 1999 to August 2004, 6 pediatric patients underwent VATS for CLD. Patients were chosen for VATS based upon surgeon's choice. Data are expressed as mean ± SD. The Children's Healthcare of Atlanta institutional review board approved this study.

Results

The types of lesions included congenital cystic adenomatoid malformations (n = 1), extrapulmonary sequestrations (n = 3), congenital lobar emphysema (n = 1), and bronchogenic cyst (n = 1). The extent of resection included lobectomy (n = 2) and excision (n = 4). Age and weight were 11.8 ± 18 months (range 6 days to 4 years) and 7.5 ± 3.6 (range 4.0-14.0) kg, respectively. Operating time was 103 ± 70 (range 38-223) minutes. Chest tube duration was 1.2 ± 0.8 (range 0-2) days. Morphine use on the first postoperative day was 0.2 ± 0.3(range 0.05-0.20) mg/kg. Length of stay was 2.5 ± 1.9 (range 1-6) days. There were no conversions to thoracotomy and no complications.

Conclusion

VATS technique appears to be a safe and effective technique in managing CLD in children of all ages. More patients, however, need to be studied.     

Video-assisted thoracoscopic surgery for children with stage II empyema

Children with stage II empyema often fail traditional medical management, frequently succumbing to the effective albeit morbid clutches of thoracotomy. Video-assisted thoracoscopic surgery (VATS) has been recently introduced as a viable and potentially less morbid alternative to open thoracotomy. We review our VATS experience in children with empyema, assessing surgical outcome. Between August 1996 and March 1999, 13 patients at our institution with stage II empyema that did not respond to conventional medical management underwent a modified VATS with decortication. Data from retrospective chart review reflects intraoperative findings and postoperative course, including average time to defervescence, removal of thoracostomy tube, and hospital discharge. VATS was completed in all 13 patients. All intraoperative cultures of pleural fluid and fibrinopurulent debris obtained at VATS showed no growth. The average time to defervescence was 2.2 days (range, 0-4 days) and to removal of thoracostomy tube 3.6 days (range, 2-5 days). Average total chest tube days in patients with pre-VATS thoracostomy (n = 6) was 14.5 days (range, 8-37 days) versus 3.1 days (range, 2-5 days) in patients (n = 7) who underwent primary VATS (t test, p < 0.05). The average time to surgical discharge after VATS was 5.8 days (range, 3 to 19 days). All patients were well on follow-up clinic visits without delayed complications. VATS can be performed safely and effectively in children with stage II empyema, thus avoiding the morbidity of open thoracotomy and decortication. Importantly, early application of VATS significantly relieves patients of unnecessary days of thoracostomy drainage.     

Bilateral staged versus bilateral simultaneous thoracotomy in the pediatric population

Aim

The aim of the study was to evaluate the safety and outcomes of simultaneous bilateral thoracotomy in pediatric patients compared with traditional bilateral staged thoracotomy.

Methods

This is a retrospective review of 30 consecutive patients 18 years or younger undergoing either bilateral staged or bilateral simultaneous thoracotomy between March 1994 and July 2004. Follow-up (mean, 47 months) was available for all patients.

Results

Thirty patients (17 boys, 13 girls; average age, 12 years) underwent bilateral staged or bilateral simultaneous thoracotomy. Eighteen patients underwent staged thoracotomy, 9 patients underwent simultaneous thoracotomy, and 3 patients underwent both procedures. Diagnosis included sarcoma (n = 21), Wilms tumor (n = 4), indeterminate pulmonary nodules (n = 3), and germ cell tumor (n = 2). When we compared outcomes for patients undergoing simultaneous versus staged bilateral thoracotomy, mean hospital stay (5.2 vs 10.6 days; P < .002), intensive care unit stay (1 vs 2 nights; P < .0001), days with tube thoracostomy (4 vs 8 days; P < .0005), and time to initiation of adjuvant chemotherapy (13 vs 30 days; P < .05) were all significantly less for patients undergoing bilateral simultaneous thoracotomy. In addition, postoperative complications were less frequent in patients undergoing simultaneous versus staged thoracotomy (0 vs 3 events; P = .25).

Conclusions

In selected patients, bilateral simultaneous thoracotomy is safe and may lessen morbidity and hospital stay while avoiding delay in initiation of adjuvant chemotherapy.     

Thoracoscopic treatment of pediatric lung abscesses

Objective

Lung abscesses in the pediatric population are relatively rare. We present our consecutive series of thoracoscopically treated pediatric lung abscesses.

Methods

A retrospective review of children who underwent thoracoscopic drainage of intraparenchymal lung abscesses between October 2006 and January 2009 at a tertiary referral center.All patients had associated parapneumonic empyema and underwent drainage of the abscess concurrently with thoracoscopic treatment of the empyema.

Results

Eleven children (4 boys and 7 girls) had thoracoscopic intervention for lung abscesses. A total of seventeen abscesses were drained. All procedures were completed thoracoscopically. There were no mortalities or long-term bronchopleural fistulas. No child required a formal thoracotomy, lung resection or a second operation. Mean duration of postoperative hospital stay was 11.0 days (range, 3-36). Mean length of stay was 19.5 days (range, 6-77 days). Mean duration of postoperative chest tube was 3.6 days (range, 2-8). Mean length to defervescence was 4.8 days (range, 1-11 days).Mean duration of postoperative antibiotics was 23.6 days (range, 3-56). Eight children had organisms identified from intraoperative cultures.

Conclusions

Thoracoscopic drainage of pediatric lung abscesses is a viable and safe treatment option. Thoracoscopic abscess drainage is associated with minimal morbidity and may result in faster recovery and a shorter course of antibiotics.     

Thoracoscopic management of postpneumonectomy empyema

Background

Even when there is no associated bronchopleural fistula, empyema is a serious complication of pneumonectomy. Aggressive surgical treatments are usually applied. However, a minimally invasive approach might achieve satisfactory results in selected patients.

Methods

Out of 17 patients presenting with a postpneumonectomy empyema (PPE), 11 had a thoracoscopic approach. There were 9 males and 2 females, (age, 38-74; mean, 59 years). Ten patients had no proven bronchopleural fistula (BPF). One of them had a minor (< 3 mm) BPF. Empyema was confirmed by thoracentesis and bacteriological examination. All patients had immediate chest tube drainage and underwent emergency thoracoscopic debridement of the empyema. No irrigation was used postoperatively.

Results

There was no mortality and no morbidity related to the procedure. The average duration of thoracoscopic debridement was 62 minutes (range: 45-80 minutes). In 8 patients the chest tube was removed between the fifth and thirteenth postoperative day (average, 8.6 days). They were discharged between the 9th and 24th postoperative day. In 3 patients, clinical and/or biological signs of infection persisted and reoperation was decided at day 5, day 10, and day 11. All 3 patients underwent open-window thoracostomy. The average follow-up of the 8 patients who underwent only thoracoscopy was 10 months (range, 2-27 months). None had recurrent empyema. The patient who presented with a minor BPF remained asymptomatic and is doing well after a 27 month follow-up.

Conclusions

Thoracoscopy might be a valuable approach for patients presenting with PPE with or without minor bronchopleural fistula.     

Esophageal stethoscope: an old tool with a new role, detection of residual flow during video-assisted thoracoscopic patent ductus arteriosus closure

Background

Video-assisted thoracoscopic surgery (VATS) has emerged as an innovative and popular procedure for closure of a patent ductus arteriosus (PDA), but is associated with a minute rate of residual or recurrent duct patency. This study aims to analyze the efficacy of intraoperative esophageal stethoscopic monitoring in reducing the incidence of residual ductal flow during PDA clipping by VATS.

Methods

Between June 1997 and October 2009, we retrospectively assessed 2000 consecutive patients with PDA who underwent VATS. During the procedure, heart sounds were monitored by the anesthesiologist through an esophageal stethoscope. Changes in continuous cardiac murmurs were recorded before and after the PDA clipping and were confirmed to disappear completely. Color flow Doppler echocardiography was performed immediately before discharge, and patients were followed monthly for 3, 6, and 12 months and then annually to confirm the absence of residual or recurrent shunt.

Results

Mean age was 6.0 years (range, 1 month-35 years), mean weight was 11.1 kg (range, 6-65 kg), and mean PDA diameter was 5.5 mm (range, 3-9 mm). Ninety-two percent of patients showed no ductal flow after a single clipping. In the other 8% of patients, residual flow was detected intraoperatively after a single clipping, but was eliminated by the second clipping. Twelve patients (0.6%) presented with residual ductal flow immediately after the operation (detected by color Doppler echocardiography), which was eliminated by thoracotomy before discharge. All patients left the hospital with echocardiography documenting no evidence of residual PDA. At follow-up, the incidence of residual patency was 0.2% (4 of 2000).

Conclusions

Our results demonstrate that the intraoperative esophageal stethoscope provides a remarkably effective technique for monitoring and evaluating PDA ligation by VATS, thus avoiding reintervention and the complications associated with residual ductal flow in most cases.     

Comparison between open and thoracoscopic resection of congenital lung lesions

Purpose

This study compares the outcome between thoracoscopic and thoracotomy resection of congenital lung lesions.

Methods

From November 2005 to August 2007, 14 consecutive cases of video-assisted thoracoscopic (VATS) lung resections have been performed in our institution. A retrospective review comparing these cases to the previous open thoracotomies for lung resection was performed. Intraoperative and early postoperative results were compared.

Results

The mean age for VATS resection was 10 months compared with 7 months for thoracotomy. There were no major intraoperative complications. One case was converted from thoracoscopy to thoracotomy, and there was one anesthetic failed attempt of VATS resection, which was then performed open. Seven VATS resections and 6 thoracotomies were for congenital cystic adenomatous malformations. Intraoperative chest drains were used for all VATS resections but only 10 of the 14 thoracotomies, one of which developed a tension pneumothorax within hours of discharge. Perioperative outcomes including time to removal of chest drain, length of postoperative intravenous opioid requirement, and hospital stay were similar for both groups. Three had postoperative complications. Operative time was significantly lower in the thoracotomy group (124 minutes compared with 170 minutes, P < .05). The subgroup of congenital lobar emphysema had a particularly prolonged VATS resection time of 220 vs 155 minutes (P < .05). The thoracotomy group was more likely to receive adjuvant regional anesthesia (12 of 14 compared with 5 of 14).

Conclusions

Thoracoscopic resection of lung lesions results in longer operative time but is a safe and feasible alternative to open thoracotomy. Congenital lobar emphysema is a subgroup more challenging thoracoscopically, and it is recommended that these should be preselected for open surgery.     

Videothoracoscopy in the diagnosis and treatment of hemothorax

Video assisted thoracic surgery (VATS) has assumed greater importance in the management of pleural diseases. From 1994 to 1998 the Authors report their experience about 11 cases of hemothoraces depending on various causes: 6 hemothoraces and 3 hemopneumothoraces, some spontaneous or iatrogenic, others in patients with chest trauma; 2 clotted hemothoraces. All patients were studied by VAT detecting the source of bleeding in 6 cases of acute hemothorax and in 3 cases of acute hemopneumothorax; in 5 cases the lesions were successfully repaired with thoracoscopic technique. In others 4 patients the VATS approach was converted to thoracotomy for the seriousness of lesions: 3 acute hemothoraces (1 patient with penetrating thoracic firearms injury, 1 patient with extended lung laceration, 1 patient with iatrogenic lesion of right subclavian artery); 1 acute hemopneumothorax in one patient with penetrating thoracic firearms injury and left hemidiaphragmatic double perforation: in this case laparotomy was also operated in order to exclude others abdominal lesions. 2 cases of clotted hemothorax were operated by VATS performing the removal of clots after their fragmentation by endobabcock and pleural irrigation-aspiration with physiological solution. No procedure related complications were occurred. The authors conclude that the video-thoracoscopic approach is certainly advantageous for the management of spontaneous, traumatic or iatrogenic acute hemothoraces. This technique permits, with minimal traumatism and very little complications, the correct therapeutic programming (VATS operation or conversion to thoracotomy). However some hemothoraces (hemothoraces in patients with serious cranial trauma, with spleen rupture, with great vessels rupture, with heart rupture or with massive post-operating hemothorax) contro-indicate the thoracoscopic treatment: immediate thoracotomy and/or laparotomy, in these cases, is indispensable. In the treatment of clotted hemothoraces the VATS is a favourable alternative to thoracotomy, reforming the pleural cavity with minimal traumatism and avoiding tardive complications.     

The role of aortopexy in severe tracheomalacia

Purpose

Aortopexy is the accepted operative treatment for severe and localized tracheomalacia (TM). The standard surgical approach involves a left anterior thoracotomy, often under bronchoscopic control. We report the results of aortopexy in 28 children with severe and localized TM; 12 had a left lateral muscle-sparing approach and one had a thoracoscopic aortopexy.

Methods

Retrospective review of patient notes was performed to note the indications, investigation findings, and postoperative course after aortopexy.

Results

The median age at aortopexy was 5 months. The indications included acute life-threatening events in 22, failure to extubate in 5, and recurrent pneumonia in 1. Fifteen had associated esophageal atresia and 13 had primary TM. Symptoms of TM were abolished in 26 of the 28 patients after aortopexy.

Conclusions

Aortopexy is a safe and reliable procedure to treat localized intrathoracic TM presenting with acute life-threatening events. It is important to exclude associated problems such as vascular rings and to ensure that the tracheomalacic portion is segmental and does not significantly involve the main bronchi. The lateral muscle-sparing thoracotomy provides good access and is more cosmetic than the standard anterior approach. We would attempt the thoracoscopic approach in older infants and children.     

Single-port thoracoscopy for the treatment of pleural empyema in children

Background/purpose

This report is an evaluation of a single-port technique for the thoracoscopic treatment of pleural empyema in children.

Methods

Ten consecutive patients with pleural empyema were treated by means of a “Single Port Thoracoscopy” (SPOT). Mean age was 6.9 years (range, 2 to 13 years). The surgery was performed 5 to 26 days after the onset of symptoms. Three patients received this treatment as the first procedure, whereas the other 7 underwent closed placement of a chest tube, 3 to 12 days before the surgery. Only 1 11.5-mm thoracoport was used. Through this single port, standard scopes and instruments were introduced simultaneously to debride and unify the pleural space.

Results

Satisfactory debridement of the pleural cavity was achieved in all cases. Mean operating time was 70 minutes (range, 60 to 140). There were no intraoperative complications. The chest tube was removed 2 to 5 days after the surgery. Eight patients remained afebrile from the day of the surgery, and 2 had mild fever that disappeared 36 hours after the surgery. Mean hospital stay after SPOT was 4 days (range, 3 to 7).

Conclusions

SPOT is a safe and effective proceeding for the treatment of pleural empyema in children with the advantage of better cosmetic results than the multiport techniques.     

Impact of concomitant thoracic interventions on feasibility of Nuss procedure

Background

This study aimed to analyze the feasibility of subsequent minimally invasive pectus repair, particularly modified Nuss procedure, combined with simultaneous thoracic procedures for different underlying intrathoracic diseases and conditions.

Methods

A total of 110 patients, who underwent minimally invasive pectus repair in Nuss technique over a 5-year period, were retrospectively analyzed concerning complications, cosmetic results, and satisfaction. Six patients (5%) underwent the Nuss procedure with concomitant thoracic interventions. Patients with prior cardiac surgery or planned redo pectus repair were not examined and were excluded. The mean age of 6 patients (3 male and 3 female) was 11 years (range, 5.5-17.2). Two patients with former left-sided transabdominal diaphragmatic hernia repair and 1 with former lobectomy of the left lower lobe underwent thoracoscopic adhesiolysis. Two underwent thoracotomy: one for closure of a recurrent left-sided diaphragmatic hernia with fundoplication owing to a large hiatal hernia, another for lobectomy of the right middle lobe owing to recurrent infections and bronchodysplasia. One patient presented with anterior mediastinal mass, which was suspected to be benign, and underwent thoracoscopic complete resection. All patients underwent a 1-stage procedure with subsequent simultaneous Nuss procedure.

Results

Simultaneous Nuss procedure was feasible without intraoperative complications in all patients (100%). Thoracoscopic adhesiolysis did not affect the feasibility of the Nuss procedure in 3 patients with former diaphragmatic hernia repair, particularly former lobectomy in one. Thoracotomy with middle-lobe lobectomy, as well as repair of recurrent diaphragmatic hernia and fundoplication in 2, did not affect modified Nuss technique and dispensed thoracoscopic guidance. Histopathologic analysis in one patient with a removed anterior mediastinal mass revealed Hodgkin lymphoma (stage IA), and the patient received multiagent chemotherapy. The postoperative course was uneventful in 5 of 6 patients. One patient required intermittent drainage of pleural effusion after simultaneous lobectomy. At follow-up (6 months-5 years), 6 patients had excellent cosmetic results and good quality of life confirmed by a questionnaire. There was no evidence of recurrent malignancy in one patient after 6 months.

Conclusions

Thoracic surgery and subsequent Nuss procedure can be performed simultaneously. Underlying conditions, such as prior repair of congenital diaphragmatic hernia or diaphragmatic eventration, as well as former lobectomy, had no impact on feasibility. Open thoracotomy can be combined with Nuss procedure dispensing thoracoscopy.     

A comparison of chest tubes versus bulb-suction drains in pediatric thoracic surgery

Background/Purpose

Chest tubes are commonly used to evacuate the pleural space of air and fluid after thoracic surgery. The safety and efficacy of postoperative traditional chest tubes (CTs) versus soft bulb-suction drains (BDs) in the management of pediatric patients undergoing thoracic procedures were investigated.

Methods

An institutional review board-approved, retrospective review was performed on all patients who required noncardiac, nontraumatic thoracic operations from January 2000 to December 2005. Patient data included BD or CT drainage, age at operation, indication for surgery, open or thoracoscopic approach, days of postoperative drainage, the development of a postremoval pneumothorax, and complications. Statistical comparisons were made using t test and χ² test.

Results

During the study period, 186 patients with complete records underwent a thoracic operation. One hundred twenty (65%) received a CT, whereas 66 (35%) received a BD. Patients who received CT averaged 5.6 days of drainage compared with 4.4 days in the group that received BD. Postremoval pneumothorax developed in 5 (4%) patients with CT compared with 4 (6%) patients with BD. Two patients in the CT group required reinsertion of another CT. None of the BD patients required further intervention.

Conclusion

For thoracoscopic and open thoracic operations, BDs are as safe and efficacious as traditional CT.     

Video-assisted thoracoscopic surgery of mediastinal bronchogenic cysts in adults: a single-center experience

Background

Mediastinal bronchogenic cysts are rarely diagnosed in adults, hence surgical experience is limited particularly with regard to video-assisted thoracoscopic surgery. In support of the thoracoscopic approach we report our single-center experience in this rare entity.

Methods

Between June 1995 and December 2002, a nonselected series of 12 consecutive patients presenting with mediastinal bronchogenic cysts underwent video-assisted thoracoscopic surgery. Six cysts (50%) had been diagnosed 2 to 22 years prior, only three of which became symptomatic. In asymptomatic patients (n = 7) surgery was performed because of increasing cyst size (n = 3), patient's request (n = 3), or suspected metastasis (n = 1).

Results

Mediastinal bronchogenic cysts were correctly diagnosed by computed tomography in 83% (10/12) and by magnetic resonance imaging in 100% (9/9). Using a three-trocar technique thoracoscopic surgery was successfully performed in 11 of 12 cases (92%). We noted no signs of acute cyst infection. No serious postoperative complications were observed. In 1 patient conversion to open thoracotomy was necessary due to extensive pleural adhesions. In another case thoracoscopic excision of the cyst wall was incomplete. Patients with thoracoscopic excision were discharged after a median of 5.5 days (range 4 to 14 days). No recurrences or complications were observed during a mean follow-up of 40.5 months.

Conclusions

Considering the low conversion and complication rate in our series, video-assisted thoracoscopic surgery should be the primary therapeutic choice among adults with symptomatic mediastinal bronchogenic cysts. Surgical intervention in patients with asymptomatic and uncomplicated cysts appears optional.     

Thoracoscopic versus open resection of congenital lung lesions: a case-matched study

Purpose

The purpose of the study was to compare the outcomes in children undergoing thoracoscopic versus open resection of congenital lung lesions.

Methods

Retrospective review of 12 consecutive children (<3 years of age) undergoing thoracoscopic resection of a congenital lung lesion between 2004 and 2005 was performed. Intraoperative and early postoperative results were compared with randomly selected age- and sex-matched (2:1) patients undergoing thoracotomy between 2000 and 2005.

Results

Twelve children underwent thoracoscopic resection and were compared with 24 that underwent thoracotomy. Seventy five percent of the lesions in both groups were congenital cystic adenomatoid malformations. There were no major intraoperative complications. Two thoracoscopic procedures were converted to a thoracotomy. Perioperative outcomes including operative time, length of stay, duration and volume of chest tube drainage, and dose and duration of intravenous opioids were similar for the procedures. However, children undergoing thoracoscopic procedures were less likely (odds ratio = 0.07) to have received adjunctive regional anesthesia. Overall morbidity was 33% thoracoscopic and 25% open (P = .70).

Conclusion

Thoracoscopic resection is a safe and feasible alternative to open resection of congenital lung lesions. Examination of long-term advantages of the thoracoscopic approach such as decreased risk of chest wall deformity and scoliosis and improved cosmesis will require longer follow-up.     

Axillary thoracotomy versus videothoracoscopy for the treatment of primary spontaneous pneumothorax

Background

A prospective, randomized study was carried out on patients with primary spontaneous pneumothorax, with the aim of determining if video-assisted thoracoscopy is superior to axillary thoracotomy in the surgical treatment of this condition.

Methods

Patients were randomly assigned to two groups; video-assisted thoracoscopy (group A; n = 46) and axillary thoracotomy (group B; n = 44). All fit the established criteria for surgical indication (relapse or persistent air leakage after pleural drainage). In all cases the treatment consisted of apical segmentectomy of the blebs or dystrophic complex and pleural mechanical abrasion. The study evaluated the following factors: postoperative blood loss, respiratory function (maximum inspiratory and expiratory pressures, forced expiratory volume in the first second and forced vital capacity), postoperative pain (analog visual scale), supplementary doses of analgesics, postoperative complications, hospital stay, and resumption of normal activity. Relapses were evaluated for the minimum period of time of two years.

Results

No significant differences were found in any of the factors studied in either group.

Conclusions

Video-assisted thoracoscopy and axillary thoracotomy offer similar results in the surgical treatment of primary spontaneous pneumothorax. The rate of complication is low and the level of pain is acceptable without long-term sequelae.
