However, the cosmetic result of single port laparoscopic totally extraperitoneal inguinal hernia repair (TEP) has not been superior to that of transabdominal preperitoneal hernia repair (TAPP). The aim of this study is to introduce and assess the Single Umbilical Tangential Incision (SUTI) for Lap-TEP repair. Methods: Forty one hernia repairs of 34 patients were performed using SUTI-TEP method. SUTI was made all along the inferolateral skin of the umbilical pit and a vertical incision of less than one centimeter was made in the supra- or infraumbilical skin if needed; the total length of the incision was 2~2.5 cm. SILS TM port and conventional instruments were used for the procedure. Results: All procedures were completed without conversion to the conventional TEP procedure. Mean operation time was 73 minutes for unilateral primary hernia, 119 minutes for bilateral primary hernia, 88.5 minutes for unilateral recurrent hernia, and 120 minutes for bilateral recurrent hernia. There were two cases of wound seroma and four cases of urinary retention postoperatively. Other significant complications were not noted. There was no recurrence of hernia during the follow-up period of one to 24 months. At routine follow-up visit at three months postoperative, the scar was barely visible and overall level of patient satisfaction was very high. Conclusion: The SUTI-TEP inguinal hernia repair is safe and shows superior cosmetic results. Further studies are required in order to assess the long-term outcome.

SUTI 배꼽접면절개방법접면절개는배꼽와 (umbilical pit) 의가운데가아니라배꼽와의측면 ( 서혜탈장위치의동측 ) 피부에말그대로접면절개를가한후복직근의전복직근초에도달하는것을의미하며, 나머지는기존의복강경전복막수술과동일하다 (Fig. 1). 배꼽모양에따라 (Fig. 2), 오메가모양을시계방향 90도혹은반시계방향 90도로돌린 rotated omega (Ω) incision 을사용 Single umbilical tangential incision (SUTI) Rectus muscle Skin and subcutaneousfat Perforators Inferior epigastric artery and vein Fig. 1.

SUTI (Single Umbilical Tangential Incision) Laparoscopic TEP Inguinal Hernia Repair 27 결과환자분포 (Table 1) 34명의환자에서 41 예의단일공복강경전복막탈장교정술을시행하였다. 남녀의비는 5.8:1 로남자에서많았으며, 단측탈장 27예, 양측탈장 7예, 원발성탈장 31 예, 재발성탈장 3예였고, 이중탈장의유형으로는간접탈장이 31 예, 직접탈장 6예, 판탈롱탈장 3예, 대퇴탈장 1예였다. 수술결과 (Table 2) SUTI-TEP 의수술시간은원발성단측탈장 73분, 양측탈장 119 분, 재발성단측탈장 88.5 분, 양측성인경우 120 분이었다. 수술직후통증을 VAS 로측정한결과 SILS TM port 의하연을제거하지않고원래모양대로쓰면서국소마취제를쓰지않은경우통증의정도가심해서평균 7.5 점을보인반면, cutted SILS TM port 를사용하고국소마취제를사용한경우평균 3.04 로나타났다. 수술직후합병증은상처장액종 2예로간단하게외래에서치료되었으며, 4명의환자에서수술직후소변저류가있었으나다음날호전되어퇴원하였다. SUTI-TEP 중기존의다공수술이나개복수술로전환한경우는없었으며, 최장 24개월동안의추적조사에서도만성통증을호소하거나, 재발된경우가발견되지않았다. 환자들의만족도는매우높았다 (Fig. 5). 고찰 단일공수술인 Single port or single incision TEP 은보통배꼽하방인 infraumbilical or 배꼽을통한 transumbilical incision Table 1. Patient demographics SUTI-TEP (41 hernias/34 patients) Age (ranges) 60.5 (27~81) Gender (M : F) 29 : 5 BMI (kg/m 2 ) (ranges) 23.52 (20.7~29.17) Hernia side (Rt : Lt : Bilateral) 20 : 7 : 7 Hernia types Primary : Recurrent 31 : 3 Unilateral : Bilateral 27 : 7 Indirect : Direct : Pantaloon : Femoral 36 : 6 : 3 : 1 으로많이시행되어왔다. 3,4 그러나 infraumbilical incision 의 경우상대적으로큰반흔 (scar) 이남아단일공복강경수술의 장점인미용적인면을추구할수없고, transumbilical 이라는 단어는실상 umbilicus 를뚫고복강내로들어간것인지, 단지 배꼽의피부를경유했다는것인지, 혹은배꼽중어느부위에 절개를가한것인지의여부는알수가없다. 5 따라서저자는이모든문제를해결하고자단일공수술시배 꼽절개를변형한접면절개인 SUTI 를사용하여단일공전복막 서혜탈장수술을시행하였다. 배꼽의모양은크게 hooded oval or T-shape, oval, horizontal, vertical, hooded vertical 등 5 가지로나뉜다 (Fig. 2). 7 SUTI 의장 점은개개인의배꼽모양에따라절개모양을다양화하여, 변 형선택하여가함으로써, 배꼽주름내에대부분의절개가위치 하므로, infraumbilical incision 처럼수술직후절개의전길이 가보이지않아미용면에서매우유리하다는점이다. 복직근의 6 pack 을나타내는건교차 (tendinous intersection) 는사람마다매우다양해서보통 1~4 개정도존재하며배꼽상 방에주로존재한다. 8 따라서 SUTI-TEP 시행과정에서배꼽상 방으로절개가가해지고복직근의뒤를통해전복막공간으로 접근할때건교차에의하여접근이힘들가능성을예상할수 있다. 그러나다행히복직근건교차는근육의전층이아닌중 간깊이의근육만이포함되며, 특히복직근전초에밀접히붙어 있고, 복직근후초와는거의유착등이없어배꼽상방의절개 로도아무런문제없이복직근과복직근후초를통하여전복막 Table 2.

SUTI-TEP 서혜탈장교정술이성공하려면 5가지요소가매우중요하다. 첫째, 환자의수술체위로양쪽팔을환자의몸에붙이는것 ; 둘째, 환자의가슴쪽에위치하는외과의의 high up position; 셋째, 배꼽의접면절개 ; 넷째, 수술직전장시간작용하는국소마취제의절개부위주입, 그리고마지막으로 cutted SILS TM port 이다. 환자의몸에팔을붙이고외과의가환자의가슴쪽에위치하여수술하면단일공수술시발생하는수술포지션에따른부담이줄어인체공학적으로좀더편한수술을하게된다. 단일공복강경수술을하는경우, 수술직후절개가들어갔던배꼽부위에심한통증을호소하는경우가있다. 복강경수술의장점이절개가적어통증이적은것도포함되는데, 절개는작은데통증이심하다면이는또다른논란을야기할수있다. 따라서저자는두가지방법을사용하여수술후통증을경감하였는데, 수술절개부위의국소마취제주입후수술하는것과 cuttted SILS 이다. 수술절개부위의국소마취제주입만으로는수술후통증감소가많지않았는데아마도 SILS TM port 의모양때문인것으로사료된다. SILS TM port 의 dimension 은위아래넓은부분이 50 mm, 길이 50 mm, waist 부분 27 mm로길이가 길고, 위아래가넓어서위아래닿는부분이눌림으로인한통증이야기될수있을것으로생각하고, SILS TM port 의아래튀어나온부분을잘라낸후사용하였다. 잘라낸후사용한또다른이유는 SILS TM port 크기가절개선이나 SILS TM port 가삽입되는복직근과복직근후초사이의공간보다커서수술시삽입이힘들었기때문이다. 아래쪽 bottom portion 을잘라내어사용한후통증의감소를경험하였다. 따라서국소마취제주입은 port entry site 에대한통증감소를목적으로하며, cutted SILS TM port 는 entry site 와 3~4 cm 떨어진부위의통증감소를목적으로한다. 본연구에서도 SILS TM port 만을사용해서수술했던경우통증이심했던반면, 장시간작용국소마취제와 cutted SILS TM port 를사용했던경우통증이매우줄어서, 이두가지요소가환자의수술직후통증을많이경감시키는역할을하여, 미용적인면에서나통증면에서 SUTI-TEP 에대한환자의만족도를더욱높이는역할을하였다. SUTI-TEP 수술결과원발성단측성서혜부탈장의경우수술시간은약 70분, 양측탈장 119 분정도소요되었다. 시간은좀더걸렸지만, 다른수술로의전환이나심한합병증등은없었다. SUTI-TEP 수술시간기존의복강경전복막탈장교정술에비하여약 10~30 분정도의시간이더소요되었는데, 6 이 Journal of Minimally Invasive Surgery Vol. 18. No. 1, 2015
SUTI (Single Umbilical Tangential Incision) Laparoscopic TEP Inguinal Hernia Repair 29 는절개선이들어가는피부에국소마취주입및 SILS TM port cutting 등수술기구에대한준비시간 ( 약 10~15 분 ) 뿐아니라피부절개및봉합시기존절개방법보다더미용적으로봉합하는데대한시간소요 ( 약 10~20 분 ) 를감안해야한다 (data not shown). 만일이를감안하면단일공수술이시간이더걸리는것은사실이지만실제전복막강내에서의수술시간의차이가아주크지는않다. 또한단일공 TEP 수술에대한다른저자의결과와크게다르지않다. 9 SUTI-TEP 수술후재원기간은하루로기존의복강경전복막탈장교정술과저자나다른저자의경험과크게다르지않았다. 6,9,10 짧게는 1개월, 길게는 24개월의추적조사에서도재발인만성서혜통증등은한예도없었고, 절개부위에대한환자의만족도는매우높았다. 비교적짧은추적조사기간이었지만 SUTI-TEP 서혜탈장교정술은기존의복강경전복막탈장교정술과비교하여수술후합병증이나재발률의차이가없이안전하고수술이가능하며, 미용적인면에서도매우우수하였다. 단일공수술인 SUTI-TEP 이기술적으로, 인체공학적으로아직은많은노력이필요하지만, 그결과와환자의만족도를볼때지속적으로추구해볼만한가치가있다고하겠다.
