Haemorrhage from smooth muscle tumours of the upper gastro-intestinal tract

Eight patients with haemorrhage from smooth muscle tumours of the upper gastro-intestinal tract were treated during a 10 year period from 1973 to 1982. Seven of the tumours were benign and one a malignant leiomyoblastoma. Seven tumours were sited in the stomach and there was one duodenal lesion. Endoscopy was performed in all eight cases and made the diagnosis definitively in four. In two cases the diagnosis was confirmed on barium meal and in the other two, diagnosis was eventually made at laparotomy. Two patients were shocked on admission and required emergency surgery. In one case a diameter greater than 10 cm suggested malignant potential and wide local resection was performed. In one other case with a tumour in the antrum, a distal partial gastrectomy was performed, and in the case with leiomyoblastoma a proximal gastrectomy was performed. One case was lost to follow-up. The mean follow-up in six cases free of disease with benign tumour was 2.6 years. The patient with a tumour of greater than 10 cm in diameter remains well at 18 months follow-up and the patient with a malignant leiomyoblastoma died 2 years after surgery.
