Sucralfate and carbenoxolone in the treatment of functional disturbances following partial gastrectomy.

30 patients submitted to partial gastrectomy (Billroth II) who later suffered digestive complaints (pain, "heartburn", bilious vomiting) showed gastric hyperemia, oedema and some erosions of the gastric stump when examined by endoscopy, the presence of cancer having been excluded by biopsy. These patients were randomly allocated into 2 groups of 15, one of which was treated with sucralfate (1 g 4 times), and the other with carbenoxolone (50 mg 4 times), daily for 8 weeks. After sucralfate the endoscopic finding showed a clear improvement in the gastric wall, accompanied by the almost complete disappearance of the complaint symptoms, in 13 cases (86.6%). After carbenoxolone the same improvement was observed at the endoscopy in 12 cases (80%), with similar recovery from symptoms. Nevertheless, no histological changes that could be attributed to the treatments were observed. In those patients whose endoscopic pattern remained unchanged by either drug, the complaints did not show any relief. No side-effects were detected during either of these drug treatments, each of which showed a similar therapeutic efficacy.
