Abstract
INTRODUCTION Controversy exists in the optimal management of adolescent and young adult primary spontaneous pneumothorax. The American Pediatric Surgical Association (APSA) Outcomes and Evidence-Based Practice Committee performed a systematic review of the literature to develop evidence-based recommendations. METHODS Ovid MEDLINE, Elsevier Embase, EBSCOhost CINAHL, Elsevier Scopus, and Wiley Cochrane Central Register of Controlled Trials databases were queried for literature related to spontaneous pneumothorax between January 1, 1990, and December 31, 2020, addressing (1) initial management, (2) advanced imaging, (3) timing of surgery, (4) operative technique, (5) management of contralateral side, and (6) management of recurrence. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines were followed. RESULTS Seventy-nine manuscripts were included. Initial management of adolescent and young adult primary spontaneous pneumothorax should be guided by symptoms and can include observation, aspiration, or tube thoracostomy. There is no evidence of benefit for cross-sectional imaging. Patients with ongoing air leak may benefit from early operative intervention within 24-48 h. A video-assisted thoracoscopic surgery (VATS) approach with stapled blebectomy and pleural procedure should be considered. There is no evidence to support prophylactic management of the contralateral side. Recurrence after VATS can be treated with repeat VATS with intensification of pleural treatment. CONCLUSIONS The management of adolescent and young adult primary spontaneous pneumothorax is varied. Best practices exist to optimize some aspects of care. Further prospective studies are needed to better determine optimal timing of operative intervention, the most effective operation, and management of recurrence after observation, tube thoracostomy, or operative intervention. LEVEL OF EVIDENCE Level 4. TYPE OF STUDY Systematic Review of Level 1-4 studies.

Oxygen saturation associated with recurrent primary spontaneous pneumothorax treated with an intercostal chest drainage. Asian J Surg 2021; 45:431-434. [PMID: 34312054 DOI: 10.1016/j.asjsur.2021.07.021] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2021] [Revised: 07/12/2021] [Accepted: 07/16/2021] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Primary spontaneous pneumothorax (PSP) is a condition that may lead to acute chest pain or dyspnea on exertion. Treatment with an intercostal chest drainage (ICD) is warranted. There is limited data on risk factors of recurrent PSP in patients treated with the ICD alone. This study aimed to evaluate risk factors of recurrent PSP in patients with PSP and treated with the ICD. METHODS This was a retrospective study and enrolled patients diagnosed as PSP and treated with an ICD. Eligible patients were divided into two groups by evidence of recurrent PSP. Baseline characteristics, physical signs, laboratory results, and duration of ICD treatment were studied and recorded from medical charts. Factors associated with recurrent PSP were computed by using multivariate logistic regression analysis. RESULTS There were 80 patients met the study criteria. Of those, 21 patients (26.3%) had recurrent PSP. Of those, 21 patients (26.3%) had recurrent PSP. There were eight factors in the final model for recurrent PSP. Only oxygen saturation at the time of diagnosis was independently associated with recurrent PSP. The adjusted odds ratio (95% confident interval) was 0.57 (0.34, 0.96). A cut point of 96% of oxygen saturation gave sensitivity of recurrent PSP of 80.95%. CONCLUSION The prevalence of recurrent PSP was 26.3% in patients with PSP and treated with the ICD. Initial oxygen saturation may be an indicator for recurrent PSP.

Thoracoscopic Management of Blebs: Resection With/Out Primary Pleurodesis. Indian J Pediatr 2018; 85:257-260. [PMID: 29076100 DOI: 10.1007/s12098-017-2485-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Accepted: 09/07/2017] [Indexed: 10/18/2022]
Abstract
OBJECTIVES To review the literature for justification of thoracoscopic management of blebs in children. METHODS PubMed database was reviewed for articles in English, Portuguese and Spanish using the key words "thoracoscopy", "bleb" and "child". Data was collected for age, gender, type of surgery performed, operating time, conversions, complications, recurrences, follow-up and mortality. RESULTS Eleven studies with total 266 patients were included (27 bilateral cases; n = 293 surgeries). Median age was 15.7 y (range 11-18 y), 225 were male (87.9%) and 31 were female (12.1%) patients. Endo GIA™ was used in 10 cases, Endoloop® in 11 surgeries, unspecified stapler devices in 150 procedures and, in 122 surgeries, instruments were not mentioned. Pleurodesis was performed in 213 (72.7%) cases. There were 5 (1.7%) conversions (adhesions n = 3, bleeding n = 1, camera failure n = 1). Complications were documented in 8 (2.7%): pneumothorax after chest tube removal 4 (drain reinsertion n = 3, reoperation n = 1); prolonged air leak 3, all submitted to che pleurodesis; bleeding requiring reoperation 1. Recurrence occurred in 25 (8.5%): 10 re-operation, 7 conservative management, 2 chemical pleurodesis, 2 chest tube reinsertions and in 4 the management was not specified. The median follow-up was 46.1 mo (range 3 mo-11 y). There were no lethal outcomes. CONCLUSIONS Although data is scarce on specific instruments used, pleurodesis is performed in 70% of cases. Irrespective of this, thoracoscopic resection of blebs can be safely offered as it has a low complication and conversion rates and no mortality.

Abstract
INTRODUCTION Spontaneous pneumothorax in pediatric patients is relatively uncommon. The management strategy varies in different centers due to dearth of evidence-based pediatric guidelines. In this study, we reviewed our experience of thoracoscopic management of primary spontaneous pneumothorax (PSP) in children and identified risk factors associated with postoperative air leakage and recurrence. MATERIALS AND METHODS We performed a retrospective analysis of pediatric patients who had PSP and underwent surgical management in our institution between April 2008 and March 2015. Demographic data, radiological findings, interventions, and surgical outcomes were analyzed. RESULTS A total of 92 patients with 110 thoracoscopic surgery for PSP were identified. The indications for surgery were failed nonoperative management with persistent air leakage in 32.7%, recurrent ipsilateral pneumothorax in 36.4%, first contralateral pneumothorax in 14.5%, bilateral pneumothorax in 10%, and significant hemopneumothorax in 5.5%. Bulla was identified in 101 thoracoscopy (91.8%) with stapled bullectomy performed. 14.5% patients had persistent postoperative air leakage and treated with reinsertion of thoracostomy tube and chemical pleurodesis. 17.3% patients had postoperative recurrence occurred at mean time of 11 months. Operation within 7 days of symptoms onset was associated with less postoperative air leakage (P = .04). Bilateral pneumothorax and those with abnormal radiographic features had significantly more postoperative air leakage (P = .002, P < .01 respectively) and recurrence (P < .01, P = .007). CONCLUSION Early thoracoscopic mechanical pleurodesis and stapled bullectomy after thoracostomy tube insertion could be offered as a primary option for management of large PSP in pediatric population, since most of these patients had bulla identified as the culprit of the disease.

Abstract
PURPOSE Primary spontaneous pneumothorax (PSP) is managed in accordance with the adult British Thoracic Society (BTS) guidelines due to lack of paediatric evidence and consensus. We aim to highlight the differences and provide a best practice surgical management strategy for PSP based on experience of two major paediatric surgical centres. METHODS Retrospective review of PSP management and outcomes from two UK Tertiary Paediatric hospitals between 2004 and 2015. RESULTS Fifty children with 55 PSP (5 bilateral) were referred to our Thoracic Surgical Services after initial management: 53% of the needle aspirations failed. Nine children (20%) were associated with visible bullae on the initial chest X-ray. Forty-nine children were assessed with computed tomography scan (CT). Apical emphysematous-like changes (ELC) were identified in 37 children (75%). Ten children had also bullae in the asymptomatic contralateral lungs (20%). In two children (4%), CT demonstrated other lung lesions: a tumour of the left main bronchus in one child; a multi-cystic lesion of the right middle lobe in keeping with a congenital lung malformation in another child. Contralateral asymptomatic ELC were detected in 20% of the children: of those 40% developed pneumothorax within 6 months. Best surgical management was thoracoscopic staple bullectomy and pleurectomy with 11% risk of recurrence. Histology confirmed ELC in 100% of the apical lung wedge resections even in those apexes apparently normal at the time of thoracoscopy. CONCLUSION Our experience suggests that adult BTS guidelines are not applicable to children with large PSP. Needle aspiration is ineffective. We advocate early referral to a Paediatric Thoracic Service. We suggest early chest CT scan to identify ELC, for counselling regarding contralateral asymptomatic ELC and to rule out secondary pathological conditions causing pneumothorax. In rare instance if bulla is visible on presenting chest X-ray, thoracoscopy could be offered as primary option.

Abstract
INTRODUCTION Congenital diaphragmatic hernia is a potentially life-threatening neonatal condition which required surgical intervention. With the advances in endosurgical instruments and techniques, thoracoscopic approach is gaining popularity as a standard procedure in the treatment of this condition. In this study, we reviewed our two centres' experience with thoracoscopic repair of congenital diaphragmatic hernia in recent years. METHODS All patients who underwent thoracoscopic repair of congenital diaphragmatic hernia between 2010 and 2013 at the two tertiary referral centres were identified. Medical records were retrospectively reviewed. Data including patients' demographics, peri-operative outcomes, length of hospitalisation and post-operative complications were extracted and analysed. RESULTS 60 patients were identified over the study period, with 46 males and 14 females. 48 patients received operation within the first 7 days of life. There were seven patients with delayed presentation and were operated after 1 month old. The average body weight was 3.03 kg. Left-sided hernia was more prevalent (n = 50). The mean operative time was 88.5 min (range 31-194 min). No conversion to open thoracotomy or laparotomy was required in any of the patients. All patients except one were intubated and paralysed in neonatal intensive care units for at least 3 days after operation. Average hospital stay was 14.6 days. There was no mortality in this series. There were five recurrences, one being the patient without post-operative paralysis, and the others with deficient posterior muscle rim. No musculoskeletal deformity was noted on follow-up examination. CONCLUSION Thoracoscopic repair of congenital diaphragmatic hernia can be performed safely in specialised centres. The post-operative recovery and cosmesis are excellent. Diaphragmatic hernia with large defect remains a challenge for surgeons.

Abstract
OBJECTIVE The purpose of this consensus conference was to determine whether video-assisted thoracic surgery (VATS) improves clinical outcomes compared with conventional thoracotomy in patients undergoing surgery for pneumothorax, and to outline evidence-based recommendations for the use of VATS. METHODS Before the consensus conference, the best available evidence was reviewed, with systematic reviews, randomized trials, and nonrandomized trials all taken into consideration in descending order of validity and importance. At the consensus conference, evidence-based interpretative statements were created, and consensus processes were used to determine the ensuing recommendations. The Medical Information Network Distribution Service in Japan (Minds) system was used to label the levels of evidence for the references and the classes of recommendations. RESULTS AND RECOMMENDATIONS The consensus panel agreed upon the following statements and recommendations for patients with pneumothorax undergoing surgery: 1. VATS is broadly indicated as surgery for pneumothorax. 2. VATS is judged to be less invasive, as it results in minimal postoperative pain, the periods of chest tube placement and hospitalization are short, and it shows a trend toward early realization of social integration. 3. There is no difference in terms of safety and complications between VATS and open thoracotomy. 4. As it is anticipated that VATS will result in a higher recurrence rate than open thoracotomy, it may be desirable to add a supplemental procedure during surgery. In summary, VATS can be recommended as pneumothorax surgery (Recommendation grade: Level B).

Abstract
PURPOSE Recurrence is the most common complication after an initial episode of primary spontaneous pneumothorax (PSP). However, preventive surgery in children remains a controversial issue. The purpose of this study was to determine predictive factors of recurrence to better inform early surgical referrals. METHODS We retrospectively reviewed all consecutive patients under 18 years of age who conservatively treated for an initial episode of PSP between March 2005 and September 2011. RESULTS One hundred fourteen patients were included in this study. The mean follow-up period was 43.1 months. Ipsilateral and contralateral recurrence developed in 47.3% and 14.0% of patients. The risk of ipsilateral recurrence for patients with or without air-containing lesions according to high-resolution computed tomography (HRCT) was 60.3% and 31.4%. In the multivariate analysis, the presence of air-containing lesions on HRCT scans and bullae on chest X-rays were independent risk factors for ipsilateral recurrence. CONCLUSION The presence of bleb or bullae on HRCT scans or chest X-rays after an initial episode of PSP was significantly related to the ipsilateral recurrence in children. If the risk factors are clarified in further studies, hospital stays and the recurrence of PSP after the first episode could be reduced with early video-assisted thoracoscopic surgery.

Abstract
PURPOSE There is controversy regarding the best way to prevent recurrences of primary spontaneous pneumothorax (PSP) in children. The purpose of this study was to evaluate the efficacy of video-assisted thoracoscopic surgery (VATS) for pediatric PSP. METHODS We retrospectively reviewed patients under 29 years of age who underwent VATS for PSP between March 2005 and February 2011. Patients were divided into 2 groups: children (under the age of 17 years) and young adults (over the age of 18 years). RESULTS Two hundred eighty-one VATS procedures in 257 patients were included in this study. The mean follow-up was 47.1 ± 20.5 months. No mortality was observed. The mean duration of pleural drainage was 3.4 ± 2.2 days. The overall recurrence rate was 6.8 %. The operative outcomes did not differ significantly. However, the recurrence rate was significantly higher in the children's group than the young adult group (10.6 vs. 3.9 %, P = 0.032). Younger age and postoperative prolonged air leak had a significantly higher risk of postoperative recurrence. CONCLUSIONS VATS is a safe and effective procedure for PSP in children. However, the risk of recurrence is increased in children and it is related to the formation of new bullae.

Abstract
Spontaneous pneumothorax (SP) occurs when air enters the pleural space in the absence of a traumatic or iatrogenic etiology and is an uncommon phenomenon in the pediatric population. Although the typical presentation has been well described in the literature, much debate still surrounds the epidemiology, pathophysiology, diagnosis, and management of this condition in the pediatric population. To date, much of the emphasis in the pediatric literature has been on surgical options. Questions still remain regarding the true incidence of this disease in children, appropriate diagnostic imaging, and treatment recommendations for practitioners in the emergency department setting. This review of the evidence seeks to elaborate on current knowledge and clinical practice, as well as the applicability of adult recommendations to the pediatric population.

Abstract
OBJECTIVES Research on spontaneous pneumothorax (SP) has focused on management strategies in adolescents and adults, yet pediatric population-based data are lacking. The objective of this study was to determine the incidence of SP in the pediatric population in different age groups. METHODS This was a retrospective analysis of patients aged 0 to 17 years hospitalized with a diagnosis of SP from the Healthcare Cost and Utilization Project Kids' Inpatient Database between 1997 and 2006. Trends of overall incidence and demographic information, including age, sex, length of stay, associated procedures, and associated conditions, were obtained and analyzed. RESULTS The overall incidence of SP in children younger than 18 years increased from 2.68 per 100,000 population in 1997 to 3.41 per 100,000 in 2006. Average age (15.1 years; SE, 0.1 years), age distribution (83% = 15-17 years old), and hospital length of stay (4.7 days; SE, 0.1 days) remained constant. Between 1997 and 2006, males rose from 3.7 times to 4.2 times as likely to develop SP as females. In 2006, 70% of all hospitalized SP patients had therapeutic procedures documented: chest tube (32%), bleb excision (20%), and thoracotomy (8%) were the most common. Emphysematous bleb (21%), asthma (10%), and tobacco use (4%) were the most common associated diagnoses in 2006. CONCLUSIONS Although uncommon in children, SP appears to be primarily a condition of males and adolescents and appears to be increasing in incidence in this population. According to these data, a large portion of children are being managed without procedural intervention.
