No. 1, 2011 급성합병성담낭염의치료에서 PTGBD 의유용성 원저 을지대학교병원외과 김정혁ㆍ박혜원ㆍ이문수ㆍ이민구ㆍ조병선ㆍ박주승 Impact of PTGBD on Patients with Acute Complicated Cholecystitis: Consecutive 4,000 Cases of Laparoscopic Cholecystectomy Jung Hyuk Kim, M.D., Hye Won Park, M.D., Mun Su Lee, M.D., Min Koo Lee, M.D., Byung Sun Cho, M.D., Joo Seung Park, M.D. Department of Surgery, Eulji University Hospital, Daejeon, Korea Purpose: The aim of this study was to determine the advantage of adequate PTGBD in acute complicated cholecystitis patients. Methods: We performed a retrospective review of a collected database from September 2001 to July 2008. Acute cholecystitis with gangrene or perforation was defined as acute complicated cholecystitis. A PTGBD was performed for these patients immediately after the diagnosis using US or CT and then a tubogram was performed after 5 7 days. After evaluating the gallbladder (GB) and common bile duct (CBD) with a tubogram, we removed the drainage tube and the patients underwent a LC after readmission. Results: Three hundred seventy four of the 893 patients who were diagnosed with acute cholecystitis underwent PTGBD. While 19 (3.2%) of the total acute cholecystitis patients were converted to open cholecystectomy due to severe inflammation, 14 (3.7%) of the acute complicated patients were converted to open cholecystectomy. In 79 patients, the pre-operative tubogram showed the presence of CBD stone and so ERCP was performed. There were no post-operative deaths. Conclusion: PTBGD in acute complicated cholecystitis patients allows the early relief of acute cholecystitis symptoms. This allows sufficient evaluation and treatment for CBD during the PTGBD state. Furthermore, this decreases the mortality and morbidity in the high-risk patients due to sufficient evaluation and management of the underlying critical disease, which allows elective cholecystectomy when the patients is in better condition for surgery. Therefore, PTGBD can be useful for acute complicated cholecystitis.

김정혁외 5 인 : 급성합병성담낭염의치료에서 PTGBD 의유용성 15 전환율은 3.2% 이었으며, 급성합병성담낭염환자에서염증으로인한개복율은 3.7% (14/374) 로급성담낭염환자에서보이는개복전환율과비슷한수치를보이며, 다른연구들에서보인개복전환율의 16 32% 에비해현저히낮은것을볼수있다. 6,7 이는 PTGBD에의해담낭과주변의염증을최소화했기때문으로생각된다. 급성담낭염에서조기에복강경담낭절제술을시행함으로써개복수술로의전환과이에대한합병증의발생을감소시키고있지만개복술로의전환이필요한경우가여전히 6 32% 남아있고개복술시수술에따른사망률도 3.4% 보고되었다. 11 특히고령이나동반질환이있는고위험군에서는 6 46% ( 평균 15%) 의수술사망률이보고되고있다. 1-3,12-17 이에대해최근에는경피간담낭조루술을시행하고환자의상태가호전된후안전하게담낭절제를시행한결과가보고되고있고 18 본원에서도 PTGBD를시행한급성합병성담낭염을포함한급성담낭염환자에서담낭절제술을시행한예와이기간중개복담낭절제술을시행한전예에서현재까지사망한환자는없어 0% 의사망률을보이고있다. 담낭결석으로수술하는환자에서총담관결석의동반비율은 5 20% 정도로알려져있는데 19,20 예측인자로는오한, 발열, 황달의증상, 확장된총담관직경, 간효소및빌리루빈상승, 담석의크기가작으면서다발성인경우, 췌장염이동반된경우등이있다. 21-24 이를확인하기위해서는혈액검사, 초음파, 담도전산화촬영, MRCP 등이이루어지지만가장좋은방법은 ERCP이다. 하지만 ERCP는침습적인검사로서모든환자에게시행하기는어려워혈액검사나초음파검사등에서총담관결석이의심되는상황에서만 MRCP와같이제한적으로시행되고있다. 25 Son 등 26 의연구에의하면 PTGBD 후의담낭조영술로담도의해부학적구조를알수있다는장점과함께총담관결석을진단하는데유용하게사용될수있다고했다. 본연구에서도급성합병성담낭염환자에서 US나 CT상에서는정상소견을보였으나 PTGBD 시행후 79명의환자에서담낭조영술에서총담관결석이의심되거나확진되어 ERCP 를시행하였고, 이중 59명 (74.7%) 에서결석이발견되었는데이는전체 ERCP상발견된 303명의환자중 19.5% 에해당되는수치로 PTGBD가수술전총담관결석의진단에도움을준다는것과수술시총담관촬영이필요치않고총담관결석이발견된경우총담관에대한수술이필요치않아환자의회복및예후에큰장점을보인다는것을알수있다. 결 급성합병성담낭염환자에서 PTGBD 시행후경과적복강경담낭절제술을시행함으로써급성담낭염의증상을조기에소실시키고환자의기왕증을확인, 치료함으로써수 론 술합병증과사망률을낮출수있으며총담관결석에대한확인과처치가가능하여치료의적절성과편의성이확보되며담낭주위와의유착을최소화하여개복담낭절제술로의전환을최소화할수있어 PTGBD 시행후경과적복강경담낭절제술을시행하는것이급성합병성담낭염환자의치료에많은도움이되리라생각된다. 참고문헌 1) Werbel GB, Narhrwold DL, Joehl RJ, Vogelzang RL, Rege RV.
