Upper gastrointestinal endoscopy (UGE) is routinely used in daily practice [1,2]. Some patients are repeatedly sent for UGE despite the fact that a previous procedure showed no abnormalities. Apparently because of recurrent or persistent complaints. Hence there can be discussion on the feasibility of a new procedure. A study was done in order to evaluate the results of a UGE if a previous one revealed no abnormalities. (See Table 1.)
