[Surgery of the goiter].
Surgery of the goiter has been greatly influenced by Theodor Kocher all over the world. Dedicated to his understanding of goiterogenesis he is considered the father of the prevention and elimination of the wide spread iodine deficiency goiter disease in Switzerland by introducing the iodinesation of salt. Therefore Switzerland is the only country in Europe, which is no longer an iodine deficiency region but remains an endemic goiter region. The traditional conservative Kocher type of surgical resection of the multinodular goiter showed to harbour the problem of a high recurrence rate. The analysis of our Bernese data (3193 thyroid operations with 4395 nerves at risk) brought us to the point to question this traditional surgical strategy. In order to lower the recurrence rate and in addition to lower surgical morbidity we started from 1990 to resect much more thyroid tissue in order to resect all pathologic thyroid tissue. This meant as a minimal surgical procedure, a thyroidectomy on one side followed by a subtotal resection on the contralateral side in case of bilateral disease. The surgical concept in parallel was supported by the novel molecular biological concept of goiterogenesis presented by our Bernese research team, which could demonstrate that the potential for goiterogenesis and clonal growth of functional and morphological independent cluster is distributed all over the whole thyroid gland. Therefore a more radical resection at the first operation will resect much more potential clones at risk to become recurrent goiters than the 'old' conservative resection type. With the more radical initial resection combined with a routine demonstration of the recurrent laryngeal nerve and the parathyroid glands we could reduce the recurrent laryngeal nerve palsy from 2.7% (nerves at risk) in the early period (1972-1990) to 0.7% with the more radical resection (1991-1996, p < 0.05). In parallel the postoperative hypoparathyroidism of the early period of 3.6% could be lowered to 1% in the actual series (p < 0.05). Theodor Kocher's conservative thyroid gland surgical concept has now one century later found a correction by a Bernese team again, which could significantly reduce the morbidity of thyroid gland surgery and as well, will greatly reduce the incidence of recurrent goiter disease after initial surgery in our endemic region.
