title: Midgut carcinoid tumours: surgical treatment and prognosis.
abstract: Midgut carcinoids originating in the small intestine are the most common cause of the carcinoid syndrome. These tumours typically progress slowly and have an extended disease course, and although they often present with metastases at diagnosis, surgical treatment has become increasingly important for their management. Surgery should include efforts to remove mesenteric metastases, which may cause severe long-term abdominal complications with typical fibrotic intestinal entrapment and small-bowel ischaemia due to compression of mesenteric vessels. Attempts should also be made to surgically remove or ablate liver metastases, since this may provide considerable palliation of the carcinoid syndrome. For patients with the carcinoid syndrome surgery is combined with continuous biotherapy with long-acting somatostatin analogues, which may alleviate symptoms and stabilize disease or slow progression. Favourable survival and appreciable quality of life can be expected with this combined treatment, even in patients with advanced midgut carcinoids.
