Abstract PDF: Background/Aims
Ischemic colitis is recognized as the most common intestinal vascular disorder, especially in the elderly. Several predisposing factors, especially a cardiac embolism, have been reported for ischemic colitis. The aims of this study were to evaluate the prevalence of cardiovascular disease and the role of echocardiography in ischemic colitis. Methods: Thirty-six patients with ischemic colitis from January 2000 to February 2007 were analyzed retrospectively. Results: The mean age of subjects was 68.8±8.4 years. The prevalence of cardiovascular disease in ischemic colitis patients was 33% (12/36 cases). There were eight ischemic heart disease cases, four valvular heart disease cases, three arrhythmia cases and one hypertrophic cardiomyopathy case. Echocardiography was performed in 21 cases; cardiovascular disease could be detected in 11/12 cases (92%) and four cases were previously unknown. Anticoagulant therapy was required in 25% of the patients. Factors influencing hospital stay were the presence of cardiovascular disease. The presence of an associated medical illness did not influence hospital stay. Conclusions: Echocardiography may be useful to evaluate predisposing factors and to determine the use of anticoagulation therapy in ischemic colitis. (Intest Res 2007;5:165-169)

A Case of Colonic Perforation following Colonoscopy in Collagenous Colitis: Youn Sun Park, Byung Ik Jang, Tae Nyeun Kim, Jong Ryul Eun, Jae Won Choi, Kyu Hyung Lee, Kyeong Ok Kim, Si Hyung Lee, Mi Jin Kim; Intest Res 2007;5(1):77-80. Published online June 30, 2007

Abstract PDF: Collagenous colitis is a clinicopathological syndrome characterized by: (1) chronic watery diarrhea and crampy abdominal pain and (2) thickened subepithelial collagen band and increased intraepithelial lymphocytes on histology. The mucosa generally appears endoscopically normal, although some nonspecific abnormalities such as patchy erythema, an abnormal vascular pattern or erythema may be found in upto one third of cases. Collagenous colitis is generally regarded as a benign disease and serious complication are uncommon. The frequency of colonic perforation in collagenous coliltis is unknown, but is probably very rare. Only 16 patients, excluding our cases, have so far been reported. We report a case of a 80-year-old woman with collagenous colitis who presented with colonic perforation two days after the colonoscopy. (Intest Res 2007;5:77-80)

A Case of Colon Mucinous Carcinoma Mimicking Diverticular Disease with Abscess on Colonoscopy: Jae Won Choi, Byung Ik Jang, Youn Sun Park, Kook Hyun Kim, Jong Ryul Eun, Tae Nyeun Kim, Yong-Jin Kim, Chang Heon Yang; Intest Res 2006;4(2):106-109. Published online December 30, 2006

Abstract PDF: A 51-year-old male visited our hospital for investigation of abdominal pain. Barium enema revealed luminal protruding mass at descending colon, but relatively intact colonic mucosal surface and several orifices with whitish exudates observed during colonoscopic examination, these findings suggested colonic diverticular disease with abscess. Also, specimen from ultrasound guided needle biopsy demonstrated chronic inflammation. Antibiotics applied, but mass lesion showed no improvement. The patient underwent operation two month later, the histologic exam demonstrated mucinous carcinoma. (Intestinal Research 2006;4:106-109)

Recur of Malignant Mixed Mullerian Tumor of the Ovary in Intestine: Ji Eun Lee, Jang Won Sohn, Hee Jung Moon, Sang Hoon Lee, Youn Sun Park, Jae Won Choi, Kook Hyun Kim, Jong Ryul Eun, Byung Ik Jang, Tae Nyeun Kim, Jae Hwang Kim, Mi Jin Kim; Intest Res 2006;4(1):53-56. Published online June 30, 2006

Abstract PDF: Malignant mixed mullerian tumor (MMMT) is rare tumor of the ovary, representing less than 1% of all ovarian malignancies. MMMT is an uncommon tumor containing epithelial and mesenchymal components. Most of all were heterologous type and 80% occur in postmenopausal women. It is a aggressive and rapidly progressive tumor. MMMT is highly malignant and the prognosis is poor because of frequent metastasis and recurrance. The survival rate is very low in spite of surgery, chemotherapy and radiotherapy. The optimal treatment is still controversial. We experienced one recur case of malignant mixed mullerian tumor of the ovary in intestine and report with brief review of literature.

Positron Emission Tomography Finding of Small Bowel Crohn's Disease: Report of a Case: Youn Sun Park, Kook Hyun Kim, Jae Won Choi, Jong Ryul Eun, Byung Ik Jang, Tae Nyeun Kim; Intest Res 2006;4(1):57-60. Published online June 30, 2006

Abstract PDF: Endoscopic and radiologic studies are frequently required in inflammatory bowel disease to determine disease activity, extent of disease, and delineating type. Positron emission tomography (PET) using fluorine-18-fluoro-deoxyglucose to identify metabolically active tissues may offer a simple noninvasive alternative to conventional studies in identification and localization of active intestinal inflammation with inflammatory bowel disease. Crohn's disease can also be detected by PET-CT. In this case, we discribe a small bowel Crohn's disease with PET-CT finding. There was intensely increased fluorine-18-fluoro-deoxyglucose uptake in terminal ileum area. (Intestinal Research 2006;4:57-60)
