The influence of pleurodesis on the outcome of primary spontaneous pneumothorax in children

Management of primary spontaneous pneumothorax in children: Current practices among Turkish pediatric surgeons

Background

This study aims to evaluate current practices in the management of primary spontaneous pneumothorax among Turkish pediatric surgeons.

Methods

Between October 2021 and November 2021, an online survey comprising 19 questions was delivered to all members of the Turkish Association of Pediatric Surgeons (TAPS). A total of 74 respondents (42 males, 32 females; mean age: 42.3±7.9 years; range, 29 to 61 years) were included.

Results

The response rate was 17.1% among all society members. The rate of utilization of computed tomography in the initial admission was 27.4%, and the rate of use in cases requiring surgical treatment was 78.4%. A total of 81% of surgeons reported that the size of the pneumothorax influenced management. For the first episode of primary spontaneous pneumothorax, 75.7% of surgeons opted for chest tube drainage, 14.9% for only oxygen administration, 4.1% for needle aspiration, and none of the surgeons preferred video-assisted thoracoscopic surgery. For patients with a persistent air leak after chest tube placement, there was a wide variation in the duration of observation before performing surgery. Video-assisted thoracoscopic surgery was the most preferred surgical intervention (75.3%) and the most preferred surgical method was stapled bullectomy (43.8%).

Conclusion

There are practice variations in the management of pediatric primary spontaneous pneumothorax among the society members. However, the majority of members seem to agree on the use of computed tomography, initial treatment, and surgical interventions.

Management of primary spontaneous pneumothorax in teenagers: An 11-year study

AIM

Management of teenagers with primary spontaneous pneumothorax (PSP) is not consensual. We report our experience over an 11-year period.

METHODS

For each patient under 20 years hospitalised with PSP from 2008 to 2018, demographic data, smoking habits, clinical presentation, hospitalisation unit, radiological management and its results, therapeutic management (observation, needle aspiration, chest tube drainage and surgery), complications, length of stay, given advice at discharge and recurrence were collected.

RESULTS

Seventy patients were included in different paediatric or adult surgery or pulmonology wards (82.9% boys; 16.8 ± 1.7 years; one severe presentation; 18/58 smokers). Chest CT-scan (n = 42/70, 60%) revealed blebs/bullae in 18/39 examinations (46.2%). Treatment consisted of observation (14/70, 20%), needle aspiration (2/70, 2.9%), chest tube (53/70, 75.7%) and video-assisted thoracoscopy surgery (27/70, 38.6%). Half patients with interventional procedure presented complications. A median of 10 chest X-rays was noted during a median stay of 8 days. Advice concerning sport practice, flying, smoking, etc., was variably delivered. PSP recurrence concerned 35/70 patients (50%) without identified predictive factors.

CONCLUSION

Compared to recent recommendations of a more conservative approach, chest CT-scan and interventional strategy are overused in our teenagers with PSP. Observation, more or less needle aspiration, should be clearly the first-line treatments.

Systematic review and meta-analysis on juvenile primary spontaneous pneumothorax: Conservative or surgical approach first?

Background

Primary spontaneous pneumothorax (PSP) prevalence is typically higher in juvenile patients than in adults. We aimed to evaluate the optimal treatment for primary spontaneous pneumothorax and its efficacy and safety in juveniles.

Materials and methods

We searched PubMed, Embase, and Cochrane databases for eligible studies published from database inception to October 10, 2020, and conducted a systematic review and meta-analysis according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The primary and secondary outcomes were recurrence rate and hospital stay length, respectively. Odds ratios (OR) and mean differences were used for quantitatively analyzing binary and continuous outcomes, respectively. In total, nine retrospective studies with 1,452 juvenile patients (aged <21) were included for the quantitative analysis. The surgical approach led to a lower recurrence rate than did conservative approaches (OR: 1.95, 95% confidence interval: 1.15–3.32). Moreover, the recurrence rate was low in patients who underwent conservative treatment first and received surgery later.

Conclusions

Surgical approach for first-line management might have a greater effect on recurrence prevention than do conservative approaches. An upfront surgery might be an optimal choice for juvenile primary spontaneous pneumothorax.

Subsequent Development of Epithelial Ovarian Cancer After Ovarian Surgery for Benign Ovarian Tumor: A Population-Based Cohort Study

Purpose

The goal of the current study is to determine the risk of subsequent development of epithelial ovarian cancer (EOC) in women after ovarian surgery for benign ovarian tumors.

Patients and Methods

We conducted the nationwide population-based historic cohort study using the National Health Insurance Research Database (NHIRD) of Taiwan. Eleven thousand six hundred twenty women who underwent ovarian surgery for ovarian benign diseases were analyzed. The collected data included age, types of ovarian surgery, medical history by Charlson comorbidity index (CCI), infertility (yes/no), pelvic inflammatory disease (PID) (yes/no), tubal ligation (yes/no), total/subtotal hysterectomy (TH/STH) (yes/no), and endometrioma (yes/no). We used the Kaplan-Meier method and the Log-rank test to evaluate the risk factors. Cox proportional hazard methods were used to evaluate risk factors for the subsequent development of EOC. Multivariate analysis using Cox stepwise forward regression was conducted for the covariate selected in univariate analysis. Hazard ratio (HR) and 95% confidence interval (CI) were calculated using the Wald test.

Results

Subsequent EOC incidence rate (IR, incidence per 10,000 person-years) of women after ovarian surgery for benign ovarian tumors was 2.98. Separating into four groups based on different age, IR of EOC was 1.57 (<30 years), 4.71 (30-39 years), 3.59 (40-49 years) and 0.94 (≥50 years), respectively. Univariate and multivariate analyses identified only high level of CCI (≥2 or more) as an independent risk factor for subsequent development of EOC in women after ovarian surgery for benign ovarian tumors (HR 59.17, 95% CI 7.50-466.80 in women with CCI level of 2 and HR 190.68, 95% CI 24.33-2494.19, in women with CCI level ≥3, respectively).

Conclusion

Our results, if confirmed, suggest that women with other comorbidities (CCI) should be well informed that they may have a higher risk of subsequent development of EOC when ovarian surgery is planned even though the final pathology showed a benign ovarian tumor.

The Evolution of Surgical Management for Children and Young Adults With Spontaneous Pneumothorax

BACKGROUND

Few studies have analyzed pediatric spontaneous pneumothorax (SPTX) nationally. We sought to better define this patient population and explore the evolution of surgical management.

METHODS

Patients (10-20 y old) with an International Classification of Diseases, Ninth Revision diagnosis of SPTX were identified within the Kids' Inpatient Database for the years 2006, 2009, and 2012. Diagnoses and procedures were analyzed by International Classification of Diseases, Ninth Revision codes. National estimates were obtained using case weighting.

RESULTS

There were 11,792 pediatric SPTX hospitalizations, and patients were predominantly male (84.0%), non-Hispanic white (69.0%), with a mean age of 17.2 y (95% confidence interval, 17.2-17.3). Overall, 52.5% underwent tube thoracostomy as the primary intervention, and more than one-third had a major surgical procedure (34.9%). From 2006 to 2012, there was an increase in bleb excisions from 81.1% to 86.9% and an increase in mechanical pleurodesis from 64.2% to 69.0%. There was a significant change from a predominantly open thoracotomy approach in 2006 (76.1%) to a video-assisted thoracoscopic approach in 2012 (89.3%).

CONCLUSIONS

Pediatric admission for SPTX results in tube thoracostomy in more than half of the cases and surgery in approximately one-third of the cases. Surgical intervention has changed to a more minimally invasive approach during the last decade, and counseling to patients and their families should reflect these updated management strategies.
