Materials and Methods: From March 2004 to May 2011, 17 patients who underwent primary percutaneous biliary stone removal (Group 1) and 34 case-matched patients who underwent primary endoscopic biliary stone removal were selected (Group 2). The inclusion criteria were as follows: patients who had 1) 15 mm bile duct stones, 2) intrahepatic bile duct stones, 3) bile duct stones with a history of previous gastrointestinal bypass surgery. In the present study were analyzed the success rates, the length of postprocedural hospital stay, the change of Amylase/Lipase values and complications post procedure. Statistical analysis was performed using paired t-test and unpaired t-test. Results: The success rate was higher in Group 1 (94.1%) than in Group 2 (85.3%). Length of post procedural hospital stay and the post procedural amylase level were significantly increased in Group 2 (p = 0.036 and p = 0.017, respectively). Conclusion: In cases of bile duct stones with difficulties in the use of an endoscopy a percutaneous biliary stone removal can be efficient as a primary treatment.

내시경적제거가어려운담관결석환자에서일차적인경피적간경유담석제거술의유용성 mm 이상이거나, 간내담관 (intrahepatic bile duct) 에있거나, 이전에위장관우회술의과거력이있는담관결석환자들에서경피적간경유담석제거술을일차적으로시행한경우와내시경적담석제거술을일차적으로시행한환자군에대한비교는없었다 (2, 8, 10). 이에저자들은상기에서언급한내시경적경로에의한담관결석제거가쉽지않은환자를대상으로일차적으로경피적간경유담석제거술또는 ERCP 를시행받은경우에대하여비교분석하였으며, 이를통해서일차적인경피적치료술의유용성에대하여알아보고자한다. 대상과방법 이번연구는환자의의무기록검토에의한후향적분석으로, 동의서면제를신청하여임상시험심사위원회승인을받아연구를진행하였다. 2004 년 3월부터 2011 년 5월까지담관결석증을진단받고경피적간경유담석제거술 (percutaneous transhepatic biliary stone removal) 또는내시경적담석제거술을받은환자를후향적으로분석하였고, 총 1147 명의환자가이에해당하였다. 담관결석증을진단받은모든환자는발열, 황달, 우상복부통증, 황달, 소화불량등의증상으로내원하였고혈액검사와복부전산화단층촬영 (computed tomography) 을시행한후담관결석을진단받았다. 이중에서내시경적경로에의해담관결석제거가쉽지않은경우로알려져있는, 즉돌의직경이 15 mm 이상이거나, 간내담관에있거나, 이전에위장관우회술의과거력이있는담관결석환자를선별하였으며각시술별환자수는 17 명과 421 명이었다. 최종적으로일차적경피적간경유담석제거술을받은 17 명 (1군; 남자 14명, 여자 3명, 평균연령 72.1 세, 범위 : 46~88 세 ) 과조건이일치하는 34명 (2군; 남자 26명, 여자 8명, 평균연령 72.1세, 범위 : 46~88 세 ) 의내시경적담석제거술시행환자를선정하여두환자군에대하여분석하였다. 환자들이이전에시행받은위장관우회술의종류는위아전절제술과동반된위십이지장문합술또는위공장문합술 (subtotal gastrectomy with Billoth I or II operation), 위전절제술과동반된식도공장문합술 (total gastrectomy with esophagojejunostomy), 담관공장문합술 (choledochojejunostomy), 유문부보존췌십이지장절제술 (pylorus preserving pancreaticoduodenostomy) 이있었다. 1군의모든환자들은담관염증상경감및시술접근경로형성을위하여경피적담도배액술 (percutaneous transhepatic biliary drainage; 이하 PTBD) 을먼저시행하고평균 6.6일 ( 간격 일수 : 0~13 일 ) 후담관결석제거술을시행하였다. PTBD 는 2% Lidocain HCI ( 제일약품, 서울, 한국 ) 국소마취제 5~10 cc를피부에주사한후초음파와투시하에 21-G 시바 (Chiba needle; M.I.Tech, 서울, 한국 ) 로천자한후시행하였다. 1군에서시행한 PTBD 의경로로우측담관을선택한경우가 13예 (76%), 좌측담관을선택한경우가 2예 (12%), 좌우측을동시에시행한경우가 2예 (12%) 였다. PTBD 후담관조영술 (cholangiography) 을시행하여담관구조와결석의위치, 크기, 개수등을미리확인하였다. 결석의크기는담관조영술상에서가장큰결석의장경으로측정하여표기하였다. 시술시기존의 PTBD 를통하여 0.035-inch 유도철사 (stiff guidewire; Radifocus R Guide Wire M; Terumo, Tokyo, Japan) 를간외담관을거쳐십이지장유두부까지지나가게한다음 8 Fr 유도관 (Arrow introducer sheath; Super Arrow-Flex R Sheath Set with Integral Hemostasis Valve/Side Port, Arrow international, INC., Reading, PA, USA) 으로교체하였다. 먼저 10 mm 4 cm 또는 12 mm 4 cm 혈관성형용풍선카테터 (Cordis R, Johnson & Johnson Company, Roden, The Netherlands) 를가이드와이어 (guide-wire) 를통해십이지장유두부를통과시킨후풍선확장 (balloon dilatation) 을 10기압으로 30초간 2회씩시행하였다. 이렇게유두부를확장시킨후결석을확장된유두부를통해십이지장안으로밀어내어제거하였다. 크기가 15 mm를넘거나유두부풍선확장술을통해결석이제거되지않는경우, 즉간내담관에있어유두부배출이어려운경우에는배액용카테터내로기계적쇄석술 (mechanical lithotripsy) 을위한바스켓카테터를통과시켜부분쇄석술을시행하여배출시키거나 7 Fr(21.5 cm sheath, 45 mm diameter, 6 cm length) 담석바구니 (Stone basket, MTW Endoskopie, Wesel, Germany) 를사용하여결석을직접포획한다음경피적으로꺼내거나유두부로밀어내어제거하였다. 시술후에는다시원래의 PTBD 카테터로교체하고 1~7일 ( 평균 3일 ) 후추적담관조영술을시행하여잔류결석유무를확인하였으며, 관찰되는모든담관결석이제거되어조영제가소장으로원활하게통과하면성공으로간주하여배액카테터를제거하였다. 잔류결석이남아있는경우에는위의시술을다시한번반복하여결석을완전히제거하고, 2~4일 ( 평균 3 일 ) 후에담관조영술을재시행하여잔류결석유무를확인후 PTBD 를완전히제거하였다. 한번의시술로잔류결석을모두제거하지못한경우에추가적인같은시술로남은결석을제거한경우도성공한것으로간주하였다. 내시경적담석제거술은환자및보호자의동의후시행되었으며, 시술 1주일전항혈소판제및항응고제의복용을중단하 226 대한영상의학회지 2014;70(3):225-231 jksronline.org

내시경적제거가어려운담관결석환자에서일차적인경피적간경유담석제거술의유용성 장염, 십이지장천공, 담관패혈증, 장기적으로는상행성담관염, 십이지장유두부협착, 재발성결석의합병증을유발하는것으로알려져있다 (16, 17, 22-25). 이연구의한계점으로는모든분석이후향적으로단일기관에서만이루어졌고, 일차적으로내시경적담석제거술을시행한 2군의환자를 1군과같은조건으로선정하였음에도불구하고선택편향이발생하였을가능성이있다는점이다. 1군과연령, 성별, 15 mm 이상의담관결석, 간내담관결석또는위장관우회술의기왕력의포함기준이일치하는 2군을선정하였으나, 일차적내시경적담석제거술을시행받은담관결석증환자 421 명중에서위장관우회술의기왕력을가진환자는총 7명만존재하였기때문에앞서일치시킨 5가지조건중에서위장관우회술의과거력은두군간에유의한차이가있었다. 또한 2군의환자중일차적인내시경적담석제거술을통하여담관결석의완전제거에실패한 8명이포함되었으며, 이환자들은이차적으로경피적간경유담석제거술을시행하여결석을완전제거하였다. 따라서이 8명의환자에서는두가지시술모두가입원기간과 Amylase/Lipase 수치에영향을주었을가능성이있다. 다만 1군은일차적으로경피적담석제거술을시행한환자군이므로, 2군과중복되는환자는존재하지않았다. 마지막으로세가지의포함기준각각에따른구체적인결과분석이미흡하다는점이다. 각기준의환자에서내시경적담석제거술에비하여경피적담석제거술은상기언급된바와같은장점을가지고있으나, 본연구에서각기준에대한개별적인치료성적에대한분석은이루어지지않았다. 따라서향후에는선택편향을배제할수있는대규모및다기관연구를통해경피적간경유담석제거술의효과및유용성과합병증및제한점등에대한더구체적이고많은연구가이루어져야할것이다. 결론적으로, PTBD 를이용한경피적담석제거술은적절한배액으로담관염을치료하는동시에돌의직경이 15 mm 이상이거나, 간내담관에있거나, 이전에위장관우회술의과거력이있는환자와같이내시경적담석제거술에실패할가능성이높은환자들에서담관결석제거에좋은치료성적을보여안전하고효과적인일차적접근방법이라고판단할수있다. 참고문헌 1.
