Zenker's diverticulum develops because of a weakness in Killian's triangle, leading to a mucosal and submucosal herniation. Its treatment has evolved from morbid surgical interventions to safer endoscopic techniques such as peroral endoscopic myotomy (Z-POEM). Despite being a safe technique, Z-POEM is not free of complications such as perforations, bleeding, pneumoperitoneum, and pneumothorax, for which new endoscopic techniques have been developed. We present the case of a 53-year-old man taken to a Z-POEM who postoperatively presented dehiscence of the mucosotomy and a mediastinal collection, managed with a vacuum-assisted endoscopic closure device.
