PURPOSE The aim of this study was to observe the clinical features of a bezoar-induced small bowel obstruction and to investigate the role of abdominal computed tomography (CT) in establishing the diagnosis. METHODS We retrospectively reviewed 20 cases of bezoar-induced small bowel obstruction in our hospital from 1996 to 2010. RESULTS Thirteen patients(More)
BACKGROUND Radioimmunoguided surgery (RIGS) appears as an efficient tool for accurate tumor detection up to the level of micrometastases by detecting radiolabeled antibody-bound tumor cells during operation. Anti-CEA-specific T84.66 fragments were examined as to whether they efficiently detected gastric cancer cells in experimental RIGS. T84.66,(More)
OBJECTIVE The objective was to assess the diagnostic performance of 64-multidetector computed tomography (CT) for blunt small bowel perforation (BSBP). MATERIALS AND METHODS The study included 106 CT examinations of surgically proven blunt bowel and mesentery injuries (78 of BSBP and 28 of non-BSBP). CT diagnosis was based on detection of bowel wall(More)
Lymphovascular invasion (LVI) is a biological manifestation of aggressive behavior in colorectal cancer. This study sought to identify and examine the association between genetic and pathologic alterations implicated in this invasive tumor progression. We consecutively recruited 81 and 79 colorectal cancer patients with and without LVI, respectively.(More)
PURPOSE The performance of 2-deoxy-2-[(18)F]fluoro-D-glucose positron emission tomography/computed tomography (FDG PET/CT) has been not established for the evaluation of recurrent colorectal cancer. The aim of this study was to evaluate the diagnostic value of FDG PET/CT in postoperative colorectal cancer patients with normal carcinoembryonic antigen (CEA)(More)
PURPOSE This study evaluated the efficacy of neoadjuvant chemotherapy combining 5-flurouracil/folinic acid with irinotecan (FOLFIRI) in colorectal multiple liver metastases regardless of resectability. METHODS Forty-four patients with multiple (at least two) colorectal liver metastases were enrolled at seven tertiary referral hospitals between May 2007(More)
Multiple jejunalgastrointestinal stromal tumors (GISTs) were found in a 52-year-old woman with a history of neurofibromatosis type 1. These tumors were composed of interlacing fascicles of uniform spindle cells with eosinophilic cytoplasm. Immunohistochemically, the tumor cells were positive for CD117, CD34 and negative for S-100, smooth muscle actin.(More)
PURPOSE The aim of this study was to investigate the incidence and spectrum of malignant tumors in Korean neurofibromatosis type 1 (NF1) patients. METHODS We retrospectively reviewed 125 patients who were diagnosed with NF1 at a single institution from 1995 to 2010. The incidence, location, histologic type, and radiologic findings of malignant tumors as(More)
Isolated diaphragmatic metastasis arising from colorectal cancer has been reported only one case in the literature presently. Here, we presented a new case and discussed the possible pathogenesis and the treatment options. A 42-year-old male patient had received anterior resection for sigmoid colon cancer. Although the increased serum CEA level was detected(More)
