Brockmann body Brockmann body Brockmann body is an endocrine organ in some teleost fish, and is composed of a collection of islet tissues. The islet tissues are in turn composed of endocrine cells which are the principal sites of insulin synthesis. They are distributed around the spleen and the large intestine. They also secrete other hormones such as glucagon and somatostatin. Hence, Brochmann body is the centre of control of blood glucose level in these fishes. Glucagon is also produced from the intestine, but Brockmann body is the major source. Increased level of glucose stimulate the Brockmann body to release insulin, while
Endocrine surgery performed by surgeons who do at least 100 thyroid operations per year.In the United Kingdom most thyroid surgery is performed by surgeons doing less than 20 thyroid operations per year. This results in a high risk of permanent voice change (up to 2%) and a high risk of parathyroid damage. In expert hands these risks should be nearer 0.5%.Permanent damage to both voice box nerves is an extreme rarity and needs in most cases a permanent tracheotomy. Endocrine surgery Endocrine surgery is a surgical sub-speciality focusing on surgery of the endocrine glands, including the thyroid gland, the parathyroid glands, the
