He reported a history of dysphagia for 3\u2005months prior to presentation, but had yet to seek medical attention. On presentation, he was hypotensive and tachycardic with a haemoglobin of 6.6\u2005g\/dL and an International Normalised Ratio (INR) of 3.9. Esophagogastroduodenoscopy was performed and showed active bleeding from Zenker's diverticulum. The patient's INR was reversed with fresh frozen plasma and his anaemia was treated with packed red blood cells. The bleeding stopped after reversal of his INR. A barium swallow confirmed a 9\u2005cm Zenker's diverticulum. The patient had a diverticulectomy and cricopharyngeal myotomy. Histology showed mild chronic inflammation of the mucosa, but no ulceration. The patient was discharged without any further bleeding episodes.<\/jats:p>","DOI":"10.1136\/bcr-2014-204677","type":"journal-article","created":{"date-parts":[[2014,6,10]],"date-time":"2014-06-10T06:14:02Z","timestamp":1402380842000},"page":"bcr2014204677","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Where's the ulcer?
