A randomized clinical trial of surgical drainage in thyroid surgery was performed on 97 patients. Morbidity was not significantly different between both groups. The length of hospital stay was shorter in the undrained group. However, this RCT is not an indication of the value of drainage after thyroid surgery because the series is too small. Using a meta-analysis of the RCTs reported it is possible to show that to drain is not useful.
对97例患者进行了甲状腺手术中手术引流的随机临床试验。两组的发病率无显著差异。未引流组的住院时间较短。然而，该随机对照试验并不能表明甲状腺手术后引流的价值，因为样本量太小。通过对所报道的随机对照试验进行荟萃分析，可以表明引流并无益处。
