Risk factors for morbidities and mortality in children following pneumonectomy

The clinical features and operation experience of multilobar involved congenital lung malformation: A retrospective cohort study

BACKGROUND

Congenital lung malformation (CLM) is usually characterized by single-lobe involvement and multilobe involvement is uncommon. There is a lack of experience in the clinical features and surgical treatment of unilateral multilobar CLM. Therefore, this study aims to summarize the clinical characteristics and evaluate the safety and feasibility of thoracoscopic lung sparing resection in the treatment of unilateral multilobar CLM.

METHODS

A retrospective study was conducted on 34 patients with unilateral multilobar CLM, and 34 unilobar patients were randomly selected as the control group in West China Hospital of Sichuan University from 2014.1 to 2021.1. Clinical, operation and follow-up outcomes were compared between the two groups.

RESULTS

Twelve (35.2%) patients developed preoperative symptoms in the multilobar group more than 4(11.7%) the unilobar group (p = 0.02), the main preoperative symptom was infection; The multilobar group and unilobar group showed significant differences in mean intraoperative blood loss (13.3 mL vs. 7.5 mL; p = 0.02) and mean surgical time (95.6 min vs. 47.5 min; p = 0.037). The median length of postoperative hospital stay and the median chest tube placement time in the multilobar group were significantly longer (5 d vs.3 d, p = 0.045; 2 d vs.1 d, p = 0.031). There were one (2.9%) patient in unilobar group and 4(11.7%) patients in multilobar group developed complications postoperatively, which is no significant differences between the two groups(p = 0.16). No complications such as thoracic deformity, mediastinal deviation, scoliosis or recurrence were observed in either group at follow-up.

CONCLUSIONS

Unilateral multilobar CLM cases are more susceptible to develop symptoms than unilobar cases. Thoracoscopic lung sparing resection in the treatment of unilateral multilobar CLM has high safety and can effectively avoid serious complications of unilateral multiple lobectomy or pneumonectomy.

Efficacy of an expandable prosthesis placement after left pneumonectomy for soft tissue Ewing sarcoma in a 5-year-old child: 10 years follow-up

We report the case of a 5-year-old girl who underwent left pneumonectomy for Ewing sarcoma of the lung. Two expandable prostheses were placed in the left hemi-thorax to prevent post-pneumonectomy syndrome and to protect the heart from radiotherapy. With a follow-up of 10 years, the procedure proved to be effective both on post-pneumonectomy syndrome and on cardiac protection.

Thoracoscopic anatomic pulmonary segmentectomy for the treatment of congenital lung malformation in children

BACKGROUND

Lung-sparing surgery has been used to treat congenital lung malformation in children, and segmentectomy has been advocated as a lung-preservation strategy. However, thoracoscopic pulmonary segmentectomy has gained limited popularity considering the complications, the potential for residual lesions, and the technical difficulties associated with this procedure. Therefore, this study aimed to investigate the safety and feasibility of pediatric thoracoscopic anatomic pulmonary segmentectomy for the treatment of congenital lung malformations.

METHODS

We conducted a retrospective review of the medical records of 568 patients who were treated at West China Hospital, Sichuan University, from January 2014 to January 2020. The patients were divided into segmentectomy and lobectomy groups according to the surgical procedures they underwent. Clinical and follow-up outcomes were compared between the two groups.

RESULTS

The segmentectomy and lobectomy groups included 206 and 361 cases, respectively. The mean intraoperative blood loss was significantly higher in the segmentectomy group (6.9 mL vs. 4.5 mL; p = 0.03). The mean surgical time was also significantly longer in the segmentectomy group, (55.6 min vs. 41.5 min; p = 0.018). However, the incidence of complications did not differ significantly between the two groups (2.9% vs. 1.1%, p = 0.21). Patients in both groups did not require reoperation or show residual lesions during hospitalization and follow-up.

CONCLUSIONS

Thoracoscopic anatomic pulmonary segmentectomy is a safe and feasible definitive lung-sparing treatment for specific cases of congenital lung malformation, and has a complication rate comparable to that of thoracoscopic lobectomy.

Pneumonectomy in a child due to belated diagnosis of foreign body aspiration: a case report

Introduction

With early diagnosis, fiberoptic or rigid bronchoscopy methods are the gold standard in the management of tracheobronchial foreign body. Otherwise, nonrecognized bronchial foreign bodies cause irreversible damage to the airways and lungs. The deficiency of the health system noted in many developing countries such as Madagascar, combined with the fundamental problem relating to children’s conditions, which are determined by social and educational factors, makes it almost impossible to provide early and appropriate management of the penetration syndrome.

Case presentation

An 11-year-old Malagasy female patient was referred to our hospital for an investigation of the etiology of the patient’s hemoptysis. The investigations revealed a localized bronchiectasis and atelectasis due to a foreign body obstructing the left main bronchus. Based on the hemoptysis and left lung almost destroyed by an occlusive lesion within, we decided to proceed with left pneumonectomy. A retrospective interrogation revealed a choking episode 4 years prior in elementary school after the child sucked on a pen cap and involuntarily aspirated it. Two years after the pneumonectomy, our patient was doing well and was asymptomatic.

Conclusion

In this case report, we describe a rare case of a late presentation of foreign body aspiration that resulted in a left pneumonectomy in a child. Despite our favorable results, pneumonectomy must be the preferred last option. Preventive actions remain the optimal approach.

Pleuropneumonectomy as Salvage Therapy in Children Suffering from Primary or Metastatic Sarcomas with Pleural Localizations

Simple Summary

Pediatric sarcoma patients with pleuropulmonary lesions have a dismal prognosis because the impossibility to achieve local control. Local therapy with radiotherapy, whether in combination with chemotherapy, appears to be insufficient to eliminate the tumor cells. The aim of this study was to determine if pleuropneumonectomy (PP) could be a therapeutic option. We retrospectively reviewed nine patients who underwent PP for pleuropulmonary localization of primary localized sarcoma or metastatic recurrence. Surgery and complications were analyzed, pulmonary function tests were conducted, and quality of life was determined. Outcome is variable, four patients died within 14 months after PP, one patient suffered from local recurrence, and four patients are in long-lasting remission. This extended operation is quite well tolerated. Lung function seems preserved, and quality of life is generally good. Because it gives improvement of survival in patients with pleural lesions, PP can be considered as effective salvage therapy in selected patients.

Abstract

Pediatric sarcoma patients with pleuropulmonary lesions have a dismal prognosis because the impossibility to obtain local control. The aim of this study was to determine if pleuropneumonectomy (PP) could be a therapeutic option. We retrospectively reviewed nine patients who underwent salvage PP for pleuropulmonary localization of primary localized sarcoma or metastatic recurrence. Surgery and complications were analyzed, pulmonary function tests were conducted, and quality of life was determined with EORTC-QLQ-C30 questionnaire. At the time of PP age was between 9–17 years. Underlying disease included metastatic osteosarcoma (n = 5), Ewing sarcoma (two metastatic, one primary), and one primary undifferentiated sarcoma. Early complications occurred in three patients. Mean postoperative hospitalization stay was 14.5 days. Pulmonary function test showed 19–66% reduction of total lung capacity which led to mild exercise intolerance but did not affect daily life. Four patients died of multi-metastatic relapse <14 months after PP, one patient had a local recurrence, and four patients are in complete remission between 1.5 and 12 years after PP. In conclusion, in this small patient group treated with a pleuropneumonectomy for primary or metastatic lesions, outcome is variable; however, this extended surgical technique was generally quite well tolerated. Postoperative lung function seems well preserved, and it seems to lead to at least an extension of life with good quality and therefor can be considered as salvage therapy.

Pneumonectomy for Pediatric Tumors-a Pediatric Surgical Oncology Research Collaborative Study

OBJECTIVE

To describe utilization and long-term outcomes of pneumonectomy in children and adolescents with cancer.

SUMMARY BACKGROUND DATA

Pneumonectomy in adults is associated with significant morbidity and mortality. Little is known about the indications and outcomes of pneumonectomy for pediatric tumors.

METHODS

The Pediatric Surgical Oncology Research Collaborative (PSORC) identified pediatric patients <21 years of age who underwent pneumonectomy from 1990 to 2017 for primary or metastatic tumors at 12 institutions. Clinical information was collected; outcomes included operative complications, long-term function, recurrence, and survival. Univariate log rank, and multivariable Cox analyses determined factors associated with survival.

RESULTS

Thirty-eight patients (mean 12 ± 6 yrs) were identified; median (IQR) follow-up was 19 (5-38) months. Twenty-six patients (68%) underwent pneumonectomy for primary tumors and 12 (32%) for metastases. The most frequent histologies were osteosarcoma (n = 6), inflammatory myofibroblastic tumors (IMT; n = 6), and pleuropulmonary blastoma (n = 5). Median postoperative ventilator days were 0 (0-1), intensive care 2 (1-3), and hospital 8 (5-16). Early postoperative complications occurred in 10 patients including 1 death. Of 25 (66%) patients alive at 1 year, 15 reported return to preoperative pulmonary status. All IMT patients survived while all osteosarcoma patients died during follow-up. On multivariable analysis, metastatic indications were associated with nonsurvival (HR = 3.37, P = 0.045) CONCLUSION:: This is the largest review of children who underwent pneumonectomy for cancer. There is decreased procedure-related morbidity and mortality than reported for adults. Survival is worse with preoperative metastatic disease, especially osteosarcoma.

Isolated unilateral pulmonary vein atresia with hemoptysis in a child: A case report and literature review

RATIONALE

Hemoptysis is an uncommon chief complaint but a distressing symptom in pediatric patients. Due to the recurrence and mortality in minor patients, an accurate diagnosis of the underlying cause is quite essential for treatment. The etiologies causing hemoptysis in children are similar to that in adults. Isolated unilateral pulmonary vein atresia (PVA), as an unusual cardiovascular anomaly, has rarely been reported to be an etiology of hemoptysis in children.

PATIENT CONCERNS

A 2-year and 11-month-old boy was admitted into our hospital with a complaint of recurrent hemoptysis for 2 months and the symptom became more aggravated in recent 4 days before admission. Physical examination was only remarkable for slightly diminished breath sounds over the left lung field, pale face, and colorless lip. Series of targeted laboratory evaluation were negative expect for anemia. Due to the identification of asymmetrical transparency of bilateral lung, slight emphysema of right lung, less volume of left lung with ground-glass opacity and reticular opacity, and ipsilateral mediastinal shift on chest CT, and varices of submucosal vessels in the left bronchial tree on the fiber-optic bronchoscope.

DIAGNOSES

It more likely indicated a congenital cardiovascular disease. The diagnosis of left isolated unilateral PVA was ultimately confirmed through chest CT angiography (CTA) with three-dimensional (3D) reconstruction.

INTERVENTIONS

Since the boy did not complain with hemoptysis after admission, respiratory tract infections seldom occurred and no pulmonary hypertension was detected, a conservative approach was chosen with periodic clinical follow-up after discussing with the cardiac surgeons and in accordance to his parents' own wishes.

OUTCOMES

Fortunately, he was doing well after 3 months of clinical observation.

LESSONS

We firstly reported a rare case of hemoptysis in children secondary to isolated unilateral PVA with no associated congenital heart disease in Chinese population. It is significant to improve the recognition and prompt diagnosis of this rare condition for pediatric clinicians, and widen the etiology spectrum of hemoptysis in children. The diagnosis of unilateral PVA should be considered for a patient with recurrent hemoptysis and imaging findings that indicate hypoplastic lung, ipsilateral mediastinal shift, and smooth margins of left atrium without evidence of rudimentary pulmonary veins.

Long-term outcomes of congenital lung malformations

Congenital lung malformations comprise a group of anatomical abnormalities of the respiratory tree including congenital cystic malformations, bronchopulmonary sequestrations, bronchogenic cyst, bronchial atresia, and congenital lobar emphysema. These anomalies are detected with increasing frequency by pre-natal sonography, but may also present for the first time with symptoms in childhood or later life. When symptomatic, there is little controversy that resection is indicated, which is usually curative. When a lesion is asymptomatic there is greater debate regarding the benefit of resection versus continued observation. This article provides an overview of the spectrum of disorders, the management options available and the long-term outcomes associated with each treatment option.
