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.
