A 69-year-old woman with a history of renal transplantation was investigated for biliary duct dilation. She was receiving treatment with prednisone and tacrolimus.
Echoendoscopy was performed with a radial scope (Olympus GF-UE160) with the patient under conscious sedation. During introduction of the endoscope, perforation was observed in the pharyngoesophageal area. The decision was made to place a fully covered self-expandable metal stent (23 × 12 mm; Wallflex, Boston Scientific), completely covering the defect in the oropharynx ([Fig. 1]). The patient was intubated first to avoid the discomfort caused by the stent, and was then moved to the resuscitation unit. The stent was removed 5 days later with apparent resolution of the perforation. Computed tomography (CT) and a barium esophagogram confirmed resolution of the defect ([Fig. 2]; [Fig. 3]). A small fluid collection at the mediastinum without air bubbles, shown on CT ([Fig. 2]), was treated conservatively with antibiotics ([Video 1]). The patient recovered completely with no symptoms of dysphagia.

Video 1 Iatrogenic pharyngoesophageal perforation treated with a fully covered self-expandable metal stent and orotracheal intubation.
Qualität:
Iatrogenic oropharyngeal perforation is a rare complication of echoendoscopy, occurring in 0.03 % of explorations [1] [2]. The rate is probably higher with echoendoscopes and duodenoscopes because of their rigidity and lateral or oblique viewing. In the oropharynx, it is not possible to close a perforation with either normal or over-the-scope clips. Other cases have been published in which resolution of the defect in 3 days was reported [3] [4], but because our patient was being treated with prednisone, we preferred to delay removal of the stent.
