BACKGROUND: Crohn's disease (CD) is a chronic inflammatory disease that has difficulty in treatment due to various complications and frequent recurrence. There have been many studies on the clinical aspects of CD in western countries, however there have been few studies in Korea. We try to perform this study to elucidate the clinical features of CD in Korea. METHODS: We retrospectively reviewed the medical records of 62 patients diagnosed as CD in Samsung Medical Center from October 1994 to July 1999 and investigated their clinical features. RESULTS: Male to female ratio was 1.7:1 and the mean age at diagnosis was 29.6 years. The most common symptom was abdominal pain (58%), followed by diarrhea. Perianal lesions were observed in 27 cases (44%) of 62 patients. Fistula was the most common (60%) among the perianal lesions, followed by abscess, fissure, and stricture. Extraintestinal manifestations were observed in 23 cases (37%) of 62 patients. Arthritis was the most common (44%), followed by oral, skin, and ocular lesions. All patients were classified into three groups on the basis of disease extent by the radiologic and endoscopic findings; combined type (66%), colitis alone (23%), and small bowel disease alone (11%). Empirical anti-tuberculous medications were administered to 28 cases (45%) of 62 patients before CD was diagnosed. The presenting features were classified into inflammatory (71%), fistulizing (14.5%), and fibrostenotic (14.5%) type. Operation was performed in 31 cases (50%) of 62 patients during clinical course. The causes of operation were fistulizing complication (48%), fibrostenotic obstruction (32%), and indefinite diagnosis (20%). CONCLUSION: We noticed little difference in the clinical features of CD in Korea compared to those of western countries. And, intestinal tuberculosis should be considered in differential diagnosis of CD in endemic areas of tuberculosis like Korea.

Gastric tuberculosis is quite rare and usually combined with pulmonary tuberculosis. Its diagnosis is so difficult as it is often unsuspected. We report a patient with gastric tuberculosis who presented with hematemesis in Korea. Upper endoscopy showed large, deep penetrating ulcer containing an exposed vessel and adherent clot in the body. Gastric biopsies revealed only chronic inflammation and no evidence of granuloma or malignancy. Diffuse mural thickening was noted on abdominal CT. The diagnosis was made postoperatively following gastrectomy for bleeding gastric ulcer. Microscopic examination of resected stomach showed peptic detritus and noncaseating granulomas. However, multiple caseating granulomas with Lagerhan's giant cells were found on the examination of lymph nodes. The patient was treated with antituberculous therapy for 12 months without any complications.

BACKGOUND/AIMS: Gastrointestinal (GI) bleeding remains a common medical problem, with morbidity and mortality rates of GI bleeding in intensive care unit (ICU) believed to have remained unchanged. There has been no report about the etiology and clinical manifestation of GI bleeding in ICU in Korea. Therefore, we performed this study to determine the frequency, etiology, risk factors, and outcome of clinically significant GI bleeding that occurred after admission to ICU. METHODS: We reviewed medical records of 1829 patients admitted to medical ICU in Samsung Medical Center from October 1994 to May 1999. Cases were enrolled the patients who developed GI bleeding more than 24 hours after admission to the medical ICU. The cases were compared with control populations: a set of ICU patients without GI bleeding matched with cases for age, gender, and length of ICU stay to evaluate the risk factors of GI bleeding. RESULTS: Clinically significant GI bleeding, confirmed by endoscopy, occurred in 71 patients of 1,829 patients (3.9%) after a mean ICU stay of 14+/-2.6 days. Gastric ulcer bleeding was the most common source of GI bleeding, accounting for 29.6% of cases overall. There were no statistical differences in underlying disease, mechanical ventilator use, heparin or steroid use, prothrombin time, prophylactic drug use such as H2 blocker and antacid use between cases and controls. However, thrombocytopenia (<50,000/mm3) was more common in cases who had GI bleeding than controls (P<0.05). CONCLUSIONS: Gastric ulcer was the most common cause of GI bleeding in ICU and careful attention was necessary to patients with thrombocytopenia (<50,000/mm3) in ICU.

OBJECTIVES: The purpose of present study is to investigate the influence of a spinal gamma-aminobutyric acid B (GABAB) receptor on a central regulation of blood pressure(BP) and heart rate(HR), and to define its mechanism in the spinal cord. METHODS: In urethane-anesthetized, d-tubocurarine- paralyzed and artificially ventilated male Sprague-Dawley rats, intrathecal administration of drugs were carried out using injecton cannula(33-gauge stainless steel) through the guide cannula(PE 10) which was inserted intrathecally at lower thoracic level through the puncture of a atlantooccipital membrane. RESULTS: Intrathecal injection of an GABAB receptor agonist baclofen(30, 60, 100 nmol) decreased both blood pressure and heart rate dose-dependently. Pretreatment with 8-bromo-cAMP(50 nmol), a cAMP analog or glipizide(50 nmol), a ATP-sensitive K+ channel blocker attenuated the depressor and bradycardic effects of baclofen (100 nmol) but not with 8-bromo-cGMP(50 nmol) a cGMP analog. CONCLUSIONS: The GABAB receptor in the spinal cord plays an inhibitory role in central cardiovascular regulation and that this depressor and bradycardic actions are mediated by the decrease of cAMP via the inhibition of adenylate cyclase and the opening of K+ channel.

Duplication of the alimentary tract is an unusual congenital anomaly which may occur at any level, from the oral cavity to the rectum. Jejunal duplication cyst is quite rare and most of them are presented in infancy with the symptoms of abdominal mass, obstruction, hemorrhage and perforation. But some cases has not been diagnosed till adult if duplication cyst was too small enough to cause symptoms. We report a case of a 28-year-old woman who presented with recurrent gastrointestinal hemorrhage as a result of an ulceration without ectopic mucosa in jejunal duplication cyst and was successfully treated with surgery.

Mesenteric vein thrombosis (MVT) is an infrequent but old form of acute mesenteric ischemia, various forms of which have been recognized through imaging techniques. Pre- viously, diagnosis was made only by a laparotomy or autopsy. MVT is an abdominal emergency that is rarely diagnosed early. Review of the literature has shown that most cases have been treated by intestinal resection, and a few by thrombectomy with or with- out resection. Most are primary thromboses, but some are related to thromboembolic dise- ases, sepsis, cirrhosis, coagulopathy, abdominal neoplasms, traurna, or use of oral contra- ceptives. We report a case of superior mesenteric vein thrombosis with acute ischemic bowel disease, diagnosed early through a duodenoscopy and definitively assessed by superior mesenteric angiography and computed tomography. The predisposing factor for this case was a pelvic abscess post placenta previa operation. The first symptoms were hematemesis and abdominal pain. An intestinal mucosal lesion and clinical symptoms were improved by only heparinization and symptomatic treatment without resection.

Purpose: We evaluated the association of body composition with long-term oncologic outcomes innon-metastatic rectal cancer patients. Materials and Methods: We included 1,384 patients with stage(y)0-III rectal cancer treated at Asan Medical Centerbetween January 2005 and December 2012. Body composition at diagnosis was measuredusing abdomino-pelvic computed tomography (CT). Sarcopenia, visceral obesity (VO), andsarcopenic obesity (SO) were defined using CT measured parameters such as skeletal muscleindex (total abdominal muscle area, TAMA), visceral fat area (VFA), and VFA/TAMA. Inflammatorystatus was defined as a neutrophil-lymphocyte ratio of ! 3. Obesity was categorizedby body mass index (! 25 kg/m2). Results: Among the 1,384 patients, 944 (68.2%) had sarcopenia and 307 (22.2%) had SO. The5-year overall survival (OS) rate was significantly lower in sarcopenic patients (no sarcopeniavs. sarcopenia; 84% vs. 78%, p=0.003) but the 5-year recurrence-free survival (RFS) ratewas not different (77.3% vs. 77.9% p=0.957). Patients with SO showed lower 5-year OS(79.1% vs. 75.5% p=0.02) but no difference in 5-year RFS (p=0.957). Sarcopenia, SO, VO,and obesity were not associated with RFS. However, obesity, SO, age, sex, inflammatorystatus, and tumor stage were confirmed as independent factors associated with OS on multivariateanalysis. In subgroup analysis, association of SO with OS was more prominent inpatients with (y)p stage 0-2 and no inflammatory status. Conclusion The presence of SO and a low body mass index at diagnosis are negatively associated withOS in non-metastatic rectal cancer patients.
