Abstract
Twenty patients took part in a controlled double blind study comparing the efficacy of colloidal bismuth and cimetidine (800 mg at night) with cimetidine alone in the treatment of ulcerative reflux oesophagitis. Colloidal bismuth 120 mg was administered through an intraoesophageal tube four times a day. Cimetidine with colloidal bismuth gives significantly (p less than 0.001) better results than cimetidine alone. Of 10 patients treated with cimetidine and bismuth, seven had no endoscopic signs of oesophagitis after three weeks and three had grade I oesophagitis. Of 10 patients treated with cimetidine alone, one had grade I oesophagitis and three grade II oesophagitis after three weeks. The remaining six still had grade III oesophagitis. This study also shows that in nine of 10 patients reflux oesophagitis was accompanied by infection with campylobacter like organisms (CLO). After treatment the bacteria disappeared promptly in five patients receiving combination therapy and in two of four treated with cimetidine alone. The possible role of CLO in reflux oesophagitis is uncertain.
