Of 118 patients treated for peptic stenosis between 1970 and 1979, 89 cases (75.4%) had developed in connection with endobrachyesophagus, i. e., as the result of primary reflux disease; 26 cases were the consequence of secondary reflux disease without endobrachyesophagus. In three cases the peptic stenosis had to be explained as the result of a local acid secretion. The treatment which followed was conservative (bougienage + Cimetidine/Antacids) or operative (bougienage + fundoplication). The results of the therapy varied according to the type of stenosis. In cases where the stenosis was located in the upper part (endobrachyesophagus), good results could be achieved with conservative therapy in 38.3% and with operative therapy, in 67.3%. The results were worse in terminal stenosis (conservative therapy, 45.5%; operative therapy, 60%). Retrospective analysis of unsuccessful treatment shows that predominantly scarred stenosis shows worse results than florid stenosis with recent esophagitis.
