Massive colonic haemorrhage--the case for right hemicolectomy

Abstract

A total of 14 patients had operations for massive colonic haemorrhage. Of the seven who had a right hemicolectomy, four had the bleeding site localised, and three had only 'equivocal' indications of a right-sided source. One of these rebled 11 months later, but all survived and are well. Of the remaining patients, two had left-sided resection, one requiring an immediate second operation for rebleeding, and five, subtotal colectomy, of whom two died. A literature review confirms the suggestion that if the bleeding site has not been identified but, nevertheless, there are clues suggesting it to be right-sided, the best results will be obtained by right hemicolectomy. Left-sided resection should be used only when there is proof of left-sided bleeding, otherwise there will be an unacceptably high mortality. No clues, 'equivocal' indications of a left-sided source, or the presence of bilateral disease, should lead the operator to perform subtotal colectomy.
