Five cases of volvulus of varying lengths of the small intestine are described. The incidence and the aetiology of the condition are briefly discussed. Shock as a feature of extensive volvulus is stressed, and its cause in these cases is related to the previous animal experimental work of others. The other clinical features are briefly described. In the management of these cases the urgency for laparotomy is stressed and immediate delivery from the abdomen of the whole small bowel is advocated. Reference is made to the literature of massive resection of the small intestine to illustrate that the prognosis is not necessarily poor when resections are extensive. [ABSTRACT FROM PUBLISHER]

This study reports one unit's experience of the value of computed tomography (CT) in the evaluation of 24 patients with large cervical and retrosternal goitres. Of these patients, 17 were thought clinically to have symptoms of tracheal compression, but the CT demonstrated significant narrowing in only 12 cases. In the other five patients, surgery was deferred and other causes for their symptoms sought and treated. Seven patients were asymptomatic and CT failed to reveal any evidence of tracheal compression in six. In the remaining patient, however, CT revealed gross narrowing and urgent surgery was performed. When compared with CT, chest/thoracic inlet radiographs were misleading in 48% of patients, with tracheal narrowing being overestimated and underestimated. We conclude that CT gives useful information about tracheal compression in patients with large multinodular goitres, and is more accurate than chest/thoracic inlet radiographs.

Recent reports have suggested an association between familial adenomatous polyposis and papillary carcinoma of the thyroid. This report describes four patients, each with intestinal polyps and thyroid or thyroglossal cyst carcinoma. One patient had a medullary rather than papillary carcinoma of the thyroid and in another the intestinal polyps were due to Peutz-Jeghers syndrome. This may indicate a wider association between thyroid carcinoma and intestinal polyps than has previously been recognised.

One hundred and seven patients with thyroid carcinoma were treated. Thirty-one per cent of the tumours were papillary, 27% were follicular, 28% anaplastic, 4% medullary, and 10% were lymphomas. In the differentiated group of tumours, lobectomy followed by suppressive doses of thyroxine was the commonest surgical treatment. This series confirms that in the absence of extrathyroid dissemination, lobectomy is a safe and effective treatment.

The outcome of 234 patients with Graves' disease treated by subtotal thyroidectomy over a 12-year period is analysed with specific reference to hypothyroidism. Of definite hypothyroid cases, 98% occurred within 2 years. Failure to develop hypothyroidism was statistically related to large remnant size and a large goitre preoperatively. Histological review showed that any degree of lymphocytic infiltration was associated with the development of hypothyroidism (50% vs 22%). Late onset hypothyroidism occurred rarely and is not an inevitable outcome of thyroid surgery in our hands.
