title: Oesophageal transit of marshmallow after the Angelchik procedure.
abstract: The oesophageal transit time of half a marshmallow was measured radiologically in 17 controls, 28 patients with gastro-oesophageal reflux pre-operatively, 36 patients soon after implantation of the Angelchik prosthesis (2-9 weeks) and in 23 patients later postoperatively (9-48 months). Sixteen postoperative patients also underwent oesophageal manometry. All control and pre-operative patients had a marshmallow transit time of less than 1 min; 67 per cent of the early postoperative patients had prolonged transit and 70 per cent of the late tests were similarly abnormal. Prolonged oesophageal transit as measured by marshmallow swallow correlated well with symptoms of solid food dysphagia. Most, but not all, patients with an abnormal marshmallow swallow had abnormal manometric findings. The oesophageal transit of solid food is significantly slowed after the Angelchik procedure and this is not a transient postoperative phenomenon.
