RESUMO
AIM: This randomized controlled study was carried out to evaluate the role of H2 receptor antagonists after simple closure of perforated duodenal ulcer. METHODS: A total of 192 patients who underwent simple closure for perforated duodenal ulcer were divided into two groups (A: study group and B: control group). Group A patients were treated with H2 receptor antagonists, while the patients in group B received placebo. Only 174 patients were available for endoscopic follow up. RESULTS: At the end of 24 weeks, only 6 patients out of 90 (6.6%) in group A as compared to 18 patients out of 84 (21.4%) in group B had persistent symptoms of ulcer disease as well as endoscopically proven ulcer (p < 0.05). CONCLUSIONS: The results indicate that H2 receptor antagonists have a definite role and endoscopic follow up is mandatory to define those cases who actually need definitive surgery.
