AlloDerm (LifeCell Corp, Branchburg, NJ, USA) 은사체에서얻은피부를효소처리를통해표피를분리한후면역반응을유발하는항원성과모든진피세포를제거하여얻어진 acellular dermal matrix이다 1. 이는콜라겐기질 (collagen matrix), 탄력소 (elastin), 프로테오글라이칸 (proteoglycan) 과기저막복합체 (basement membrane complex) 로이루어져있으며, 연부조직결손, 구강점막질환, 비천공, 고막천공과복부결손등에사용되고있다. 2004년 Butler 와 Prieto 2 는복부수술에서 AlloDerm 은이식후변성되고반흔조직이적으면서도혈관이풍부한조직으로대체되어주위구조물과의예방적방벽을형성함으로써유착을방지하는것 Copyright c The Korean Society for Surgery of the Hand 57

Treatment of Complex Open Wounds Using AlloDerm in Hand and Foot 간이었다 (Table 1). 세명의환자에서술후2개월경경미한비후성반흔 (hypertrophic scar) 이발생하였으나추적관찰에서반흔구축 (contracture) 이발생한예는없었다. 7명의환자에서신전건의손상이있었으며, 이중 2명의환자에서술후평균 30개월의추적관찰이가능하였다. 신전건이노출된수배부의개방성창상을갖고있던이들 2명의환자에서 AlloDerm 과자가피부이식을병행하여시행한후노출되었던다섯개의신전건의기능회복의정도를분석하였다. 이를위해손가락각관절의능동운동범위를측정하고이를합산하여 total range of active motion (TRAM) 의범위로삼고반대측정상수지의 TRAM (Table 2 3,4 ) 과의백분율로환산함으로써비교하였다. 평균 TRAM은해당정상수지의 89.2% 수준이었다 (Table 3). 1. 증례 1 10세여자환자로자동차를타고가던중차가전복되는사고로오른쪽손을유리창에부딪혀생긴손등의연부조직결손을주소로내원하였다. 내원당시두번째와세번째손가락의등쪽부위에피부전층과피하층을포함한연부조직결손이있었으며, 인지와중지의신전건이노출되어있었다. 입원후 7일간고식적치료로서육아조직의형성을유도하였다. 이 Tabl e 2.

Total range of motion of the index and middle fingers was 86.5% of the normal side. 염 (tenosynovitis) 이의심될때는혈액순환이풍부한피판을사용하는것이좋다. 하지만소아나노인, 전신상태가불안정한환자에서는피판술을적용하기힘들고, 장기간의입원과치료로인해많은시간이필요로하게된다. 또한피판이전술은피부이식술보다실패율이높고, 실패하면공여부의유병등그후유증이훨씬심각하다. 공여부에따라서는심각한조직결손혹은장해가발생할수도있다. 또한피판의특성상이전후필요이상의용적으로인해이차적수술이필요한경우가생길수있다. 따라서보다간단하고수월하게재건이가능하고환자의위험부담이적은여러방법들이연구되고있는데, 그중인공진피 (artificial dermis) 와피부이식을이용한재건방법이다. 일반적으로피부이식의생착은수혜부바닥으로부터자라올라오는혈관과의접합으로이루어지므로수혜부가건이나골혹은골막이노출되어혈액순환이좋지않은경우완전한생착을기대하기힘들다. 그러나최근 Chen 등 5 은골혹은골막이노출된하지의연부조직결손환자에서일차로인공진피 (artificial dermis) 를이식하고 2-4주후자가부분층피부이식을하여좋은결과를얻었다고보고하였다. 또한 2008년에 Jung 등 6 은두피에두개골이노출된연부조직손상환자에서두개골바깥층을제거후 AlloDerm 과부분층피부이식을이용해피복한증례를보고하였다. 2008년에 Wong 등 7 이쥐실험을통해 AlloDerm 이이식후약 3일경부터신생혈관생성을일으킨다고보고하였다. 기존의여러연구결과들을종합해볼때, AlloDerm 과자가부분층피부이식을병행할경우혈액순환이좋지않은연부조직결손부위를재건하는데있어기능적으로, 외형적으로비교적만족할만한결과를얻을것으로기대된다. 본연구에서는수부나하지에건, 골, 골막이노출된결손부위에 AlloDerm 과피부이식술을동시에시행하였고, 모든증례에서피판술못지않게좋은결과를얻을수있었다. 특히수부의복합손상인경우인대의유착없이활주운동 (gliding motion) 을회복하는것이재건의핵심인데, 본연구에서수술후평균 30 개월추적관찰했을때반대편손과비교하여평균 60

5 Hyung Min Hahn, et al. Treatment of Complex Open Wounds Using AlloDerm in Hand and Foot Fi g. 2. Photographs of the hand in 9-year-old male who underwent AlloDerm graft and split thickness skin graft to cover and exposed 3 rd,4 th,5 th extensors on the dorsum of left hand following avulsion injury by escalator belt (A-C). Twenty six months after operation, total range of motion of the 3 rd,4 th,5 th, fingers was 91% in average of the normal side (D-F). 89.2% 의능동운동범위를회복하는것을확인할수있었다. 이는 2007년 Choi 등 8 이토끼실험에서파열된굴곡건의일차봉합부위에 AlloDerm 을감싸건주위유착 (peritendinous adhesion) 이방지됨을확인한결과와일치한다. 또한요골전완피판 (radial forearm flap) 의공여부를 AlloDerm 을이용해피복한경우에도건의유착을예방할수있다고보고하였다 9. AlloDerm 이여러연구에서유착을방지한다고알려져있지만자세한기전은아직밝혀지지않았다. 아마도창상의안정화와관련이있을것으로생각된다. 최근 Yim 등 10 이보고한연구에서 AlloDerm 을이용해재건한화상창상에서 trans-epidermal water loss가더안정적이라는결과를얻었다. 본연구에서는건이노출된수부와골이노출된하지의연부조직결손이있으면서피판술을사용할수없는경우에서 AlloDerm 과자가부분층피부이식술을동시에시행함으로써기능적으로, 외형적으로만족할만한결과를얻을수있었다. 결론 저자들은건이나골이노출된수부, 족부의개방성창상에 AlloDerm 과자가피부를동시에이식하여치료하였다. 이는기술적으로비교적쉬울뿐아니라수술시간도기존의피판술보다훨씬단축시킬수있다. 또한안정적인피부이식생착률을기대할수있고안정된창상재건과함께인대의유착없이활주운동능력을회복하여만족할만한치료결과를얻을수있다. 참고문헌 1.

Materials and Methods: Seven cases of hand and 4 cases of foot were treated with combined AlloDerm graft and split thickness skin graft in a single stage for managing the soft tissue defect of extremities where bone, periosteum, or tendon were exposed but flap operation was not feasible. The mean postoperative follow-up period was 30 months (range: month). Postoperatively, we assessed graft taking rate, wound healing process, and the recovery of motion of hand and foot. Results: AlloDerm and skin graft were readily assimilated into the wound in all cases. The mean postoperative range of motions of the 5 fingers with exposed digital tendons were 89.2% of the normal side. Reconstructions of wound in the foot were successfully settled without unstable scar or ulcer in all cases. Conclusion: Composite grafting with AlloDerm and autologous skin graft for reconstruction of complex open wound in hand and foot where deep structures are exposed provides stable reconstruction of the wound with high taking rate, successful recovery of tendon gliding motion by preventing adhesion.
