[Assessment of drain insertion in thyroid surgery?].
BACKGROUND
Although generally recommended the benefit of suction drains in thyroid surgery is not proven.


METHODS
Therefore, we started a prospective randomized trial including all patients who were referred to our institution for resection of an euthyroid goiter (n = 52 with drains and 48 without). On the third postoperative day as well as four weeks later the patients were questioned and physically examined, including an ultrasound of the neck and, if present, the measurement of a hematoma.


RESULTS
Two patients had to be reoperated due to a hemorrhage detected by the drains. Further the study revealed that patients without drains left the hospital significantly earlier (3.9 vs 4.6 days, p = 0.006). On the other hand the hematoma size in this group was larger than in the group with drains (1.9 ml vs. 0.9 ml, p = 0.016). The other clinical parameters were comparable in both groups. Four weeks postoperatively no differences were detected.


CONCLUSIONS
So far neither our results nor those in the literature could prove that severe postoperative hemorrhage can be recognized or treated faster with the use of drains. Although drains reduce the size of hematomas significantly, the quantity is too small for any clinical relevance. Based on these results a general insertion of drains after resection of an euthyroid goiter is not recommended.
