Total thyroidectomy with a modified Miccoli's approach for treatment of Graves' disease--feasibility and its applying techniques / 浙江大学学报·医学版

ABSTRACT

<p><b>OBJECTIVE</b>To assess the feasibility and relevant applying techniques of total thyroidectomy for Graves' disease with a modified Miccoli's approach.</p><p><b>METHODS</b>Forty-two patients with Graves' disease consecutively received the radical operation from June 2002 to December 2004.The modification includes (1) Incision extending according to the degree of lobe enlargement (3-6 cm, average 4 cm); (2) A space maintain-regulating device was used to change dimensionally the volume of working space (mainly height) when specific manipulation needed; (3) A volume-reducing resection step was performed for the gland with degree III hyperplasia by cutting off the middle-inferior part of the lobe prior to endoscopic lobectomy. The approach was designed to mainly use ultrasonically-activated scalpels, with suction-dissector or others as supplementary instruments. During the operations, a method of "sequenced dissect-coagulate-cut" was employed to directly divide all branches of thyroid vessels without ligation or application of hemoclips.</p><p><b>RESULTS</b>All procedures were completed successfully. None of them were converted to open surgery due to uncontrolled bleeding or severe postoperative hematoma. No severe complications occurred, except 2 cases who suffered from temporary hoarseness.</p><p><b>CONCLUSION</b>Total thyroidectomy for Graves' disease can be safely performed with the modified Miccoli's approach by using ultrasonic scalpel and the space maintain-regulating device. Application of these adaptive reforms can obviously reduce the difficulties in manipulation, and thus, make the usage of this minimally invasive design also clinically possible for even radical treatment of the gland.</p>
