RT Journal Article SR Electronic T1 Zenker’s diverticulum complicating achalasia: a ‘cup-and-spill’ oesophagus JF BMJ Case Reports FD BMJ Publishing Group Ltd SP bcr2013200702 DO 10.1136/bcr-2013-200702 VO 2013 A1 Sayles, Mark A1 Harrison, Laura A1 McGlashan, Julian A A1 Grant, David G YR 2013 UL http://casereports.bmj.com/content/2013/bcr-2013-200702.abstract AB A 72-year-old woman presented with long-standing gastro-oesophageal reflux, regurgitation of swallowed food and worsening cervical dysphagia. Fluoroscopic barium oesophagography revealed a posterolateral pharyngeal pouch (Zenker’s diverticulum (ZD)) complicating a ‘cup and spill’ oesophageal deformity with a smoothly tapered segment at the gastro-oesophageal junction. CT and high-resolution manometry confirmed that the underlying abnormality was a massively dilated oesophagus with aperistalsis and pan-oesophageal pressurisation, consistent with a diagnosis of oesophageal achalasia (type II). She underwent endoscopic stapled diverticulotomy, with good symptomatic relief. We discuss the aetiology of ZD, its management and the association here with oesophageal achalasia.
