title: [Thyroid surgery: generalist or specialist?].
abstract: BACKGROUND
  Thyroid surgery is done in Germany in a considerable numbers of operations (about 110,000 per year). To perform thyroid operations by so called "generalists" or "specialists" have been discussed intensively, however, this issue have not been analyzed in detail.
  
  
  METHODS
  Study material comprised 16,500 consecutive thyroid operations with 30,000 operated sites that have been prospectively documented in the German Thyroid Multicenter Study performed 1998 through 2001. Quality of surgery were analyzed by calculating the inverse relationship between volume and outcome (complication rate).
  
  
  RESULTS
  To achieve complication rates (permanent unilateral recurrent laryngeal nerve paralysis and hypocalcemia) of < 1 % (primary surgery) or < 3 % (redo surgery) the minimum number of thyroid operations of lower level of experience (e. g. benign nodular goiter) per year was n=30. The minimum number of operations with higher level of experience was significantly lower (n=3-12) due to the higher level of experience of operating surgeons. In contrast to the rates of postoperative hypocalcemia the rates of postoperative recurrent laryngeal nerve paralysis was clearly related to the number of thyroid operations performed.
  
  
  CONCLUSIONS
  The high number of thyroid operations in Germany with about 20 % of operations of high level experience are requiring surgical curricula and hospital structures that offer as well generalists as specialists to treat the broad spectrum of thyroid diseases accordingly. To lower the complication rate especially of difficult thyroid operations the level of specialization in Germany have to be increased.
