However, this method is not accurate for mass resection. Indocyanine green is commonly employed in breast cancer surgery when finding sentinel lymph nodes using a near-infrared indocyanine green fluorescence. The present study was conducted to demonstrate the usefulness of a method of mass excision of the intraductal papillary lesion using a near-infrared fluorescent camera by injecting indocyanine green into the lesion under ultrasound guidance. Methods: From October 2014 to May 2015, 10 women who were diagnosed with intraductal papilloma by ultrasonography and biopsy at our hospital were operated on by a single surgeon. Indocyanine green was injected into the lesion under ultrasound guidance. After injection, mass excision was performed using a near-infrared camera. The size of the resected lesion and the operation time were reviewed. Results: The mean size of the specimen was cm and the operation time was 36.5 minutes. Conclusion: It is useful for the surgeon and the patient to conduct mass excision of the papilloma lesion using a near-infrared fluorescent camera by injecting indocyanine green into the lesion under ultrasound guidance. However, we studied just 10 cases to date and also there was no comparative group. Therefore, Further studies are needed.

따라서광범위하게유방절제술을시행하게되므로불필요하게정상조직까지제거하게되고유방의모양변형, 장액종이발생하여환자에게통증을유발하게하는등의문제가생기게된다.

2 J Surg Ultrasound Vol. 4, No. 2, 2017 을점차적으로넓히면서병변을찾아절제하는것이이상적이나 (microdochectomy) 이러한방법은병변에확실하게접근할수없으며수술후병변이확실하게절제되었는지육안으로확인할수없어정확도가떨어진다. 따라서광범위하게유방절제술을시행하게되므로불필요하게정상조직까지제거하게되고유방의모양변형, 장액종이발생하여환자에게통증을유발하게하는등의문제가생기게된다. 이방법이외에도메틸렌블루등을사용하기도하나메틸렌블루는유방실질조직으로들어가게되면시야가확실하게보이지않으며메틸렌블루로인해병변주위가흐려져서경계가분명하지않게되어정확도가떨어지게되며이방법또한광범위하게유방절제술을시행할수밖에없게된다.(3-7) 인도시아닌그린은유방암수술에있어감시림프절생검술에사용하고있다.(8-10) 인도시아닌그린을주사용수와희석하여근적외선형광카메라로비추면형광색으로빛나는성질이있어화면을통해볼수있으며 (Fig. 1) 따라서감시림프절이형광색으로빛나면서화면을보면서감시림프절생검술을편리하게할수있다 (Fig. 2). 따라서본연구에서는이러한인도시아닌그린의특성을이용하였으며초음파가이드하에인도시아닌그린을병변에주사하여근적외선형광카메라를사용하여관내유두 종을절제하는방법이유용함을보여주고자하였다. 방법 2014년 10월부터 2015년 5월까지본센터에서유방초음파를시행한후이상소견으로초음파유도하총생검조직검사를시행하여관내유두종으로진단된여자환자 10 명을대상으로하였으며단일술자를통하여수술을시행하였다. 본연구는명지병원임상시험위원회 (IRB) 의승인을받았다. 이후승인된동의서를사용하여수술전환자에게수술방법에대한설명과함께환자의동의하에본연구를시행하였다 (IRB No. MJH ). 생리식염수 10 cc와인도시아닌그린 1 cc를혼합하면 Fig. 3과같이육안으로는옅은녹색을띠게된다 (Fig. 3). 수술실에서전신마취하에먼저인도시아닌그린을상기방법으로혼합하고이렇게혼합한인도시아닌그린과식염수혼합용액 0.5 cc를초음파유도하에관내유두종이보이는병변내로주입하였다 (Fig. 4A). 다발성병변인경우에는하나의병변당 0.5 cc씩주입하였다. 이렇게초음파유도하에병변내로주입하면유관이늘어나는모습이보이면서정확하게병변에들어갔는지여부를초음파화면으로직접실시간으로확인할수있다 (Fig. 4B). 초음파 Fig. 1.

를이용하여병변에인도시아닌그린식염수혼합용액을주입한후모니터로연결된근적외선형광카메라 (Fig. 5) 를사용하여병변에비추어보면피부주위및유방병변에밝게빛나는형광색의모습을화면을통해볼수있다 (Fig. 6).

절제한병변조직에근적외선형광카메라를사용하여비추어보면유관을따라병변이염색된것을확인할수있었으며따라서실시간으로육안으로직접절제연을확인할수있었다 (Fig. 6C).

수술 1일전초음파로관내유두종으로진단된병변의피부에마킹을하여표시하여놓았으며수술중표시된부위를따라병변을절제하였다. 결과 환자의임상적특징에대해서살펴보면 10건의환자의평균연령은 47.

(1,2) 그러나이병변은보통크기가크지않고잘만져지지않기때문에수술적절제에있어병변을찾아절제하는것은쉽지않다. 따라서수술전에 MRI를사용하여병변을확인하는방법이있으나비용적인면에서효율성이없으며수술중정확도가떨어지는단점이있다.(11,12) 통상쓰는와이어를이용한 ductoscope 로유관내병변을찾아보는방법은유관으로 scope 을넣고와이어를넣어병변을넓게하면서병변을찾아절제하는것이이상적이나이러한방법은병변에확실하게접근할수없으며수술후병변이확실하게절제되었는지육안으로확인할수없다. 이에따라광범위하게유방절제술을시행할수밖에없게된다. 또한 ductoscope 를사용하는데익숙한숙련된술자가아니면어려운수술방법이기도하다.(3,4) 이방법이외에도메틸렌블루등을사용하기도하나메틸렌블루는유방실질조직으로들어가게되면수술하고있는유방조직이메틸렌블루로인하여염색되어병변주위가흐려지고경계가분명하지않아시야가뿌옇게되어정확하게병변을알수없고결국완전절제연을확보하기위해무리하게광범위한유방절제술을시행할수밖에없게된다.(5-7) 초음파유도하에 hook wire를사용하여 localization 을시행하는방법은수술실에서한다면시간을줄일수있으나수술중절개창을열고시야확보를위해움직이다보면 wire가빠지거나위치가움직여지면서변동이생기 게될수있는경우가있어병변에정확하게접근하기어려울수있다. 본연구방법을이용하면수술중에도 hook wire 처럼위치가바뀌거나병변이벗어나게된다던지빠진다든지하는경우가없이수술도중에계속해서형광카메라를비추면서확인가능하기때문에정확도가떨어지지않는다. 또한 ductoscope 를사용하여와이어를넣는방법도수술시간이외에수술실에하든, 수술실들어오기전에하든준비시간이꽤필요하다는단점이동반된다.(5,6) 그러나본연구방법을사용하면환자가불편하거나통증을느끼는불편감을없앨수있어고통을줄일수있다. 또한술자도수술전에시간을들여병변을찾는시간을줄일수있으며이에따라수술시간및수술전준비시간그리고환자가준비하는데사용하는시간을절약할수있는장점이있다. 메텔렌블루는비용적인면에서는유용하지만염증반응등을일으켜유방조직이나피부병변에이물질을만들거나괴사를만드는부작용이동반될수있다.(13) 그러나메틸렌블루와같은단점이인도시아닌그린에서는없다. 인도시아닌그린과생리식염수를혼합한용액은인체에반응을일으키지않고부작용을일으키지않는물질로이러한부작용이적은물질이며 FDA 의승인을받았으며본센터에서도승인을받아사용하였으며환자에게도상기염증반응으로인한부작용은없었다.(9,10) 초음파유도하에병변으로인도시아닌그린과생리식염수를혼합한용액을주입하는것은 targeting 하는시간이길게걸리지않는다. 그렇기때문에단시간에수술할수있으며수술시간이매우단축되어본연구에서는평균 36.5분밖에걸리지않았다. 또한수술실에서환자에게통증이나불편감을주지않고도사용할수있으며바로초음파화면을통하여유관이늘어나면서병변에정확하게용액이들어갔는지를실시간으로확인할수있으며본연구에서도 10건에서모두 100% 의정확도를보였다. 본연구방법은수술하는도중에도병변의절제연을확인하면서술자가수술할수있는것이큰장점이다. 다른방법과달리수술에서의수술시야를흐리거나방해하지않으면서도근적외선형광카메라를비추면바로염색된곳이보이기때문에수술중정확한병변확인이가능하며절제면을확실히확인하여절제조직을최소화할수있다. 또한정확하게절제되어절제연이확실히확보되었는지 39

6 J Surg Ultrasound Vol. 4, No. 2, 2017 를절제조직에근적외선형광카메라를직접절제조직에비추어한번더확인할수있다 (Fig. 6C). 본연구방법은절제면이적어지게되어유방의모양변형을막을수있고수술후생기는통증그리고장액종등의부작용을줄일수있어환자의불편감을줄여줄수있으며, hook wire을사용한 localization에비하여술자에게도쉽게수술중정확하면서도간편하게그리고필요한만큼절제연을최소화하여수술시간을단축시킬수있음을알수있으므로매우의미가크다고하겠다. 그러나본연구는 10건을대상으로하여사례가많지않고비교군또한사례가적어좀더많은사례를모아추가적인연구를진행하는것이필요하겠다. 결 론 초음파유도하에병변에인도시아닌그린용액을주입하고근적외선형광카메라를이용하는방법으로관내유두종병변을절제하는것은환자와술자에게매우유용하다고하겠다. 다만증례가많지않고비교군도적어이에대한추가적인연구가필요하다.
