The solid bolus oesophageal egg transit test: Its manometric interpretation and usefulness as a screening test

Abstract
The standardized 99mTc‐labelled solid bolus oesophageal egg transit test (OET) was developed for assessing oesophageal motility. Its value in detecting oesophageal motility disorders was compared with oesophageal manometry in 102 symptomatic patients. Of 32 patients with normal OET, 22 (68·8 per cent) had normal manometry, whereas of 61 patients with abnormal manometry, 51 (84 per cent) had abnormal OET (χ2 = 15·82, P2 = 5·14, P2 = 7·85, P2 = 20·47, P2 = 17·22, P<0·001 respectively). The solid bolus oesophageal transit test provides an objective screening test of specific oesophageal motility disorders and should be performed before oesophageal manometry.
