Emergency repair of traumatic avulsion of the right main stem bronchus using biliary stent in a 6-year-Old girl: A case report.

Introduction: Pediatric thoracic trauma is a rare condition, but results in high levels of morbidity and mortality. These injuries are often more devastating in the pediatric population due to differences in children's anatomy and physiology relative to adult patients. Tracheobronchial injuries secondary to blunt trauma are difficult to diagnose compared to penetrating trauma. So, a high index of suspicion is of utmost importance. Case presentation: We report a case of a 6-year-old girl who experienced complete avulsion of the right main bronchus. The patient presented with extensive emphysema and severe respiratory distress with bilateral tension pneumothorax. Endotracheal intubation and two thoracostomy tubes were applied. Pneumothorax and a massive air leak persisted on the right side. After thoracotomy, right main bronchus avulsion was present and then repaired by end-to-end anastomosis and muscle flap. minimal air leaks from right chest tubes and partially expanding right lung on chest X-ray are seen after that. So, reinforcement by biliary (instead of bronchial) stent was performed because unavailability of bronchial stent with the desired size at that time. Discussion: Traumatic tracheobronchial damage occurs in just 0.05-3% of all pediatric thoracic traumas. It's fatal condition especially in first hour. With proper recognition and management of these injuries, there is an associated improved long-term outcome. This article reviews the current literature and discusses the initial evaluation, current management practices, and future directions in pediatric thoracic trauma. Conclusion: Biliary stent placement could be a reasonable treatment option for tracheobronchial damage.

Endoscopic Management of Unusual Bezoar in a Prader-Willi Syndrome Patient.

Bezoar occurs due to the ingestion of inedible material. The most common bezoar is a phytobezoar, which results from the ingestion of indigestible food particles found in vegetables and fruits. Other types include trichobezoar, which involves hair, lactobezoar, which involves milk products, pharmacobezoar, which involves medication, and in unusual cases, bezoar may involve different materials such as metals, plastics, and paper. We are presenting a case of a 19-year-old patient, a known case of Prader-Willi syndrome, who presented with difficulty breathing and tachypnea after aspiration of grape particles, and then he started to complain of melena and vomiting of dark content. He was admitted for urgent bronchoscopy and endoscopy, which showed a bezoar composed of grapes and threads. He was managed endoscopically by removing most of the threads and grape particles and releasing the tangled threads to facilitate its migration distally. Follow-up endoscopy showed complete resolution of the previously noticed content. We reported this case to discuss the endoscopic management of unusual bezoar involving threads.
