Flexible upper videoendoscopy through a modified endoscopy mask in infants and young children

Evaluation of the Explorer Endoscopy Mask(©) for esogastroduodenoscopy in children: a retrospective study of 173 cases

AIMS

The aim of this study was to evaluate the usability and safety of the Explorer Endoscopy Mask(®) (EM) as an alternative to endotracheal intubation in children undergoing elective esogastroduodenoscopy (EGD) under general anesthesia (GA).

METHODS

This study was a retrospective observational study. The study was undertaken at the pediatric digestive endoscopy suite in the Cliniques universitaires Saint-Luc, Brussels, Belgium. We retrospectively analyzed the occurrence of minor and major airway-related adverse effects during pediatric EGD procedures performed under GA with the EM between June 2014 and March 2015.

RESULTS

During the study period, 173 patients underwent EGD. Their mean age was 8.4 years (median: 9.1 years, range 4 months to 16 years). Mean duration of endoscopy (from insertion to removal of the endoscope) was 12.6 min (median: 12 min, range 3-47 min). The use of EM was uneventful in 159 (92%) cases. There were 24 airway-related adverse events in 14 children. Hypoxemia (SpO2 <90%) (13 events, 7.5%) was the most commonly encountered complication followed by laryngo- or bronchospasm (five events, 2.89%), cough (five events, 2.89%), and intubation (one event, 0.58%). No cases of regurgitation/aspiration were observed.

CONCLUSIONS

Our data support the EM use in pediatric EGD. There were few transient respiratory adverse events which were easily solved with minor interventions.

The role of rigid and flexible bronchoscopy in children

Bronchoscopy for paediatric respiratory disease is a routine procedure in paediatric pulmonology. Rigid bronchoscopy is now much less commonly used than flexible bronchoscopy. Technological advances have brought better picture quality and easier storage of video documentation. Indications with clear clinical benefit are congenital or acquired unexplained airway obstruction. In pulmonary infections or infiltrates in immunodeficient or immunosuppressed children not responding to empirical treatment a pathogen may be identified by bronchoscopy and bronchoalveolar lavage (BAL). Bronchoscopy and BAL can be indicated in children with unusual presentations of chronic cough or wheeze, and cystic fibrosis. The use of transbronchial biopsies (TBB) is established in paediatric lung transplantation. New applications and techniques are being developed, such as endobronchial ultrasound and transbronchial needle biopsy of lymph nodes and the role of airway stent placement have become better understood.
