We performed hand-assisted laparoscopic surgery for a 67-year-old male with a 5.6 cm sized abdominal aortic aneurysm. To the best of our knowledge, this is the first report in Korea. After an initial hand dissection of the abdominal aorta under laparoscopy, we performed proximal anastomosis and distal abdominal. aorta suture ligation through a 6 cm abdominal incision. Distal anastomosis was done at the bilateral common femoral arteries. He resumed his oral intake 6 hours after the surgery and discharged at the $4^{th}$ postoperative day.

Holstein 우유가 식욕감소와 함께 갑자기 유량이 줄어들고 복부의 타진시 심한 통증과 신음을 나타내어 방사선 및 초음파로 확인하였는데, 방사선 투시소견(fluoroscopy)상 길이 10cm의 직선형 금속성이물이 제2위벽을 관통하여 있었으며 초음파상으로는 제2위벽의 장막과 횡격막의 유착을 관찰하였다. 금속성 이물을 제거하기 위하여 탐색적 개복술을 실시 하였으나 복부의 심한 섬유소성 유착으로 이물을 제거하지 못하고 magnet와 항생제 및 수액을 실시 하였는데 수술후 점차 식욕 및 유량을 회복하였다. 대동물에서는 창상성 복막염에 대한 방사선 투시 및 초음파의 진단과 magnet등의 투여가 매우 유익한 방법이었다.

Congenital interruption of the inferior vena cava (IVC) can lead to secondary hepatic congestion, portal hypertension, and liver cirrhosis. A 49-year-old woman was admitted to the gynecology department with symptoms of menorrhalgia, known uterine myoma, and anemia. Abdominal computed tomography (CT) and venography performed at our hospital revealed congenital interruption of the IVC. The patient underwent retrohepatic cavoatrial bypass surgery with a polytetrafluoroethylene (PTFE) 16-mm ringed graft via posterolateral thoracotomy, and recovered without major complications. A retroperitoneal approach via posterolateral thoracotomy provides appropriate visualization during dorsal cavoatrial bypass in treating patients with congenital interruption of IVC.

Edwards Duromedics mechanical valve was introduced into clinical use in 1982 and is still being used today after several modifications. Valve-related complications after mechanical valve replacement are thiombo-embolism, endocarditis, valve malfunction, valve leaflet escape and fracture. Incidence of valve leaflet escape is very low. A 40 year-old male patient who had undergone mitral replacement with a 31mm Edwards Duromedics mechanical valve(model

A diverticulum is a blind pouch communicating with the gut. The term "diverticulitis" indicates inflammation of a diverticulum or diverticula, which is commonly accompanied by gross or microscopic perforation. Acute diverticuitis is a rare disorder in early childhood. Itis difficult to diagnose acute right colon diverticulitis from common causes of RLQ pain. We report a case of acute diverticulitis in the right colon in a 6-year-old girl. She complained of typical RLQ pain mimicking acute appendicitis,but was diagnosed with acute diverticulitis by CT scanning. Conservative treatment failed because of peritonitis due to perforation of an inflamed diverticulum. After the diverticulcetomy, the symptoms resolved.

We have experienced 25 cases of aortic aneurysm from October 1987 to January 1996. Patients ranged in age from 26yrs to 73yrs(mean age 52. Syrs). There were 13 males and 12 females. Eighteen cases were thoracic aneurysm and seven were abdom nal aneurysm. The cause of aneurysm were dissecting in 16cases aneurysms and non-dissecting in 9 cases. Risk factors of aortic aneurysm were hypertension, hypercholesterolemia, Marfan's syndrome. In thoracic aneurysm patients, 1'S cases of dissecting aneurysm underwent aneurysmectomy and replacement of vessel interposition graft with or without coronary artery implantation on the graft. 6 cases of non-dissecting aneurysm underwent operation with same policy as dissecting aneurysm. In 7 case of abdominal aneurysm,all patients underwent aneurysmectomy and graft interposition with straight i)r Y graft. Thcre were 5 postoperative death(mortality 20%). Several cases of complications were improved with proper managements. All survivors showed improvement in clinical symptom and sign and discharged without specific complications.

복부 MRI 영상에서 간의 인식은 간에 존재하는 질병을 파악하는 것뿐만 아니라 간에 대한 치료 방법이나 수술 방법을 결정하는 중요한 정보를 제공한다. 따라서 본 논문은 복부 MRI 영상에서 이러한 간 영역과 간의 혈관을 자동으로 검출하는 알고리즘을 제안한다. 제안 알고리즘은 1단계로 Region Growing의 개선된 방법으로 초기 설정된 간 영역의 외곽선 정보를 이용하여 씨앗점을 설정해 간 영역을 초기 분할한다. 2단계로 분할된 영역 경계선의 지역적 최소값을 이용하여 경계선의 보정 작업을 수행한다. 이후 3단계로 추출된 간 영역을 기반으로 영상 개선 후, 인페인팅(In-painting) 기법을 활용하여 간 영역 내부의 혈관 부분을 검출하게 된다. 제안 알고리즘의 평가는 전문의의 수작업 결과와 비교하였고, 결과 82.5%의 평균 정확도를 보여 제안 알고리즘의 효과적인 간혈관 검출을 확인하였다. 향후 본 연구의 확장으로 검출된 혈관 영역의 3D Volume Rendering 연구를 수행할 예정이다.

Mycotic anuerysms are uncommon but it is a fulminant infectious process frequently resulting in rupture and death if not properly treated. Commonly known it as infected aneurysm caused by noncardiogenic bacteremia. We experienced a case of infected aneurysm of the abdominal aorta that ruptured into the retroperitoneum. A 57 year old man was admitted with lower back pain, fever and palpable mass. It was identified as an inf cted abdominal aneurysm with staphylococcal septicemia. He underwent resection of aneurysm and replacement with a prosthetic graft and prolonged postoperative organism-specific antibiotics therapy. He recovered well and discharged without complications postoperatively.

The graft infection within the abdomen is a notorious condition, which usually develops serious complications of anastomotic rupture or distal embolism that ended in death. There has been many controversies in the treatment of an aortobiiliac graft infection and varying results have been reported. The authors treated a case of aortobiiliac graft infection after abdominal aortic aneurysm surgery. The operation was performed with re-aortobiiliac bypass using bilateral superficial femoral veins. The result was successful.

Background: The principal surgical technique for treating an abdominal aortic aneurysm since the 1960s has been the transperitoneal approach, yet there have been some recent studies that have reported improved surgical results with using the retroperitoneal approach. However, there are only limited clinical Korean studies that have, compared between the transperitoneal and retroperitoneal approaches. Material and Method: This study included 36 patients who had been diagnosed as having an aneurysm of the abdominal aorta and they were surgically treated between January 2001 and July 2007. The patients were subdivided into the retroperitoneal approach group (n=17) and the transperitoneal approach group (n=19), and they were compared in terms of the preoperative risk factors, the postoperative complications and the operative mortality. The risk factors of operative mortality risk and long-term survival for the 36 patients were assessed by the Kaplan-Meier method. Result: There were no significant differences between the groups in terms of gender, age, the underlying disease, a history of smoking, rupture of aneurysm, the preoperative symptoms, the operation time and the incidence of postoperative complications. However, the duration of postoperative fasting, the number of days of having an indwelling nasogastric tube and the length of the stay in the intensive care unit were significantly short for the retroperitoneal approach group (p<0.05). There was a 16.7% rate of operative mortality (6/36) and five of the deaths were attributed to preoperative ruptured aneurysm. On univariate analysis, a higher preoperative serum creatinine level (SCr ${\geq}$1.8 mg/dL, p=0.016) and ruptured aneurysm (p<0.001) were the significant risk factors of operative mortality. As assessed by the Kaplan-Meier method, the long-term survival was comparable between the groups and the five-year survival rate of all the patients was 57.5%. Conclusion: In the present study, a retroperitoneal approach has several advantages such as a shorter intensive care unit stay, a shorter duration of postoperative fasting and a shorter duration of an indwelling nasogastric tube. Therefore, unless there is any contraindication for a retroperitoneal approach, it could be considered as a primary surgical access for repairing an abdominal aortic aneurysm.
