Analysis of the effect of ultrasound knife assisted low small incision thyroid operation

Objective To discuss the clinical curative effect of ultrasound knife assisted low small incision thyroid operation.Methods According to the digital table ,100 patients with nodular goiter who were treated with operation were divided into the small incision group and control group ,50 cases in each group .The patients in small incision group were given the ultrasound knife assisted low small incision thyroid operation , while the patients in control group were given the traditional thyroid operation .The operation time , incision length , operative blood loss , postoperative visual analog scale （VAS） of pain scores,length of stay（LOS） and postoperative complications were observed and compared in the two groups .Results The operations in two groups were both successful .The operation time,incision length,operative blood loss,LOS,VAS of pain scores 12 h and 24 h after the operation in the small inci-sion group were much better than those in the control group （t=2.91,2.93,2.17,2.22,2.24,2.87,all P〈0.05）. The incidence rate of postoperative complication in the small incision group was lower than that in the control group （χ2 =4.33,P〈0.05）.Conclusion Compared with traditional thyroid operation ,ultrasound knife assisted low small incision thyroid operation has the following advantages to treat nodular goiter ：shorter operation time ,smaller operation wound,lighter postoperative pain,better cosmetic effect,less postoperative complication and etc .
