OBJECTIVES: We evaluated the relationship between pretreatment clinical parameters and lateral pelvic node (LPN) recurrence in patients with rectal cancer treated with a combination of curative resection and chemoradiotherapy (CRT) and attempted to identify the patients who might benefit from LPN dissection. METHODS: This study involved 900 patients between June 2001 and June 2009. Pretreatment clinical parameters including radiological size of LPN were analyzed to identify risk factors associat

Contrast-enhanced gray scale harmonic sonography showed the typical vascularity of a spoked wheel pattern during the vascular phase and persistent enhancement on serial acoustic emission imaging in most cases of hepatic focal nodular hyperplasia, and thereby it can be a promising technique in noninvasive diagnosis of this entity.

Transrectal ultrasonography (TRUS) has been widely accepted as a popular imaging modality for evaluating the lower rectum, anal sphincters, and pelvic floor in patients with various anorectal diseases. It provides excellent visualization of the layers of the rectal wall and of the anatomy of the anal canal. TRUS is an accurate tool for the staging of primary rectal cancer, especially for early stages. Although magnetic resonance imaging is a modality complementary to TRUS with advantages for eva

The size and signal intensity of LPLN before and after CRT are useful MRI findings to predict LPLN metastasis and are helpful to determine the indications for LPLD.

For local staging of rectal cancer, 3-T MRI is more accurate than MDCT for determining the depth of tumor invasion and the extent of lymph node metastasis.

Growing teratoma syndrome can be manifested as intraperitoneal masses with an increased fatty or cystic component. Radiologists should consider GTS when there are such masses on follow-up imaging studies in patients with malignant ovarian GCT.

본 연구에서는 다수의 공적개발원조 수혜국들을 대상으로 원조수혜의 이유에 대한 분석을 실시한다. 원조수혜의 이유들에 대해 이론적으로 논의한 후 경험적 분석을 통해 현실에서도 원조수혜의 이유들이 원조수혜국들의 원조수혜에 영향을 주는가를 분석한다. 이때 본 연구가 특히 관심을 갖는 원조수혜의 이유는 ‘원조수혜국의 열악한(bad) 거버넌스’이다. 그동안 원조수혜국의 열악한 거버넌스 개선은 원조수혜국들이 원조공여국가들로부터 원조를 제공받는 이유들 중 하나로 언급되어 왔다는 점에서, 그것이 경험적 분석에서도 유의미하게 나타나는지를 분석하고자 하는 것이다. 여기서 특별히 중점적으로 살펴볼 것은, 1990년대 후반 이후 원조수혜국들의 원조수혜의 이유가 ‘이행조건으로써 거버넌스 개선’에서 ‘선택조건으로써 거버넌스 개선’으로 강조점이 변화되었다는 점에서, 경험적 분석에서도 과연 그러한 변화가 나타나고 있는가에 대해 분석하는 것이다. 분석결과는 공적개발원조 활동에 대한 이론적 시사점과 OECD/DAC

Adjacent-organ injuries by ePTFE graft after LDLT were rare but present. Interventional procedures, adhesion of the bowel wall and early occlusion of the grafts were possible risk factors.

Barium-based fecal tagging using both the 40% w/v and the 4.6% w/v barium suspensions showed moderate tagging efficacy. The preliminary comparison did not demonstrate a statistically significant difference in the tagging efficacy between the use of the two tagging agents, despite the tendency toward better tagging with the use of the 4.6% w/v barium suspension.

BACKGROUND/AIMS: Alcohol and the hepatitis B virus (HBV) exert synergistic effects in hepatocelluar carcinogenesis. We aimed to elucidate the clinical significance of the antibody to hepatitis B core antigen (anti-HBc) and occult HBV infection on the development of hepatocellular carcinoma (HCC) in patients with alcoholic liver cirrhosis (LC). METHODS: Patients with alcoholic LC alone (n=193) or combined with HCC (n=36), who did not have HBsAg or antibody to hepatitis C virus were enrolled. Clin
