From January 1988 to December 1994, endoscopic sphincterotomy with stone extraction was attempted in 395 patients with common duct stones at Yeungnam University Hospital. Endoscopic sphincterotomy was successful in 389 patients(98.5 %), and clearance of the duct was achieved in 364 patients with an overall success rate of 92.2%. After sphincterotomy, stone extraction by basket or balloon was undertaken in 298 patients without lithotripsy, and stones could be extracted after fragmentation of stones in 19 patients. In 47 patients, stones were passed into duo denum spontaneously. There were 6 cases of sphincterotomy failure due to large periampullary diverticulum or previous gastrojejunostomy. In patients with success ful sphincterotomy, endoscopic stone extraction was failed in 25 cases due to 14 large stones, 5 bile duct strictures, 4 impacted stones, and 2 cases of technical fail ure. Complications were developed in 13 patients(3.3%); 8 pancreatitis and 5 bleedings. All of them were improved with medical therapy only. Despite relatively high success rate and low complications of the endoscopic management of choledocholithiasis, there were significant difficulties in removing large stones. Developement of more effective and inexpensive methods of lithotripsy, and the search for rapidly effective solvent dissolving stones were needed.

Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) with uncertain etiopathogenesis. CD can involve any site of gastrointestinal tract from the mouth to anus and is associated with serious complications such as bowel strictures, perforations, and fistula formation. The incidence and prevalence rates of CD in Korea are still lower than those of Western countries, but have been rapidly increasing during the past decades. Although there are no definitive curative modalities for CD, various medical and surgical therapies are currently applied for diverse clinical situations of CD. However, a lot of decisions on the management of CD are made depending on the personal experiences and personal dicision of physicians. To suggest preferable approaches to diverse problems of CD and to minimize the variations according to physicians, guidelines for the management of CD are needed. Therefore, IBD Study Group of the Korean Association for the Study of the Intestinal Diseases has set out to develop the guidelines for the management of CD in Korea. These guidelines were developed using the adaptation methods and encompass the treatment of inflammatory disease, stricturing disease, and penetrating disease. The guidelines also cover the indication of surgery, prevention of recurrence after surgery, and CD in pregnancy and lactation. These are the first Korean guidelines for the management of CD and the update with further scientific data and evidences is needed.

Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) with uncertain etiopathogenesis. CD can involve any site of gastrointestinal tract from mouth to anus and is associated with serious complications such as bowel stricture, perforation, abscess, and fistula formation. The incidence and prevalence rates of CD in Korea are still low compared with those of Western countries, but are rapidly increasing during the past decades. The diagnosis of CD is a challenging issue in some clinical situations and it is often difficult to differentiate CD from intestinal tuberculosis or Beh?et's enterocolitis which are more prevalent in Korea than in Western countries. Therefore, IBD Study Group of KASID has set out to establish the diagnostic guideline of CD in Korea. There is no single gold standard for the diagnosis of CD and diagnosis is made by clinical evaluation including detailed history, physical examination, and combination of endoscopic findings, histology, radiologic findings and laboratory investigations. The typical symptoms of CD are abdominal pain, diarrhea, and weight loss especially in late adolescence or early adulthood. Initial laboratory investigations include CBC, C-reactive protein, and serum chemistry. Ileocolonoscopy and biopsies are recommended as the first line procedures to establish the diagnosis. Typical endoscopic findings of CD are non-continuous distribution of longitudinal ulcers, cobblestone mucosal appearance, and aphthous ulcerations arranged in a longitudinal fashion. The evaluation of small bowel with small bowel follow-through is recommended for suspected CD to establish diagnosis and to determine the extent and location of disease. Focal and patchy chronic inflammation, focal crypt irregularity, and non-caseating granulomas are usual microscopic features of CD. This is the first Korean diagnostic guideline for CD and needs revision with further data on CD in Koreans.

Moderate to severe pulmonary hypertension, mean pulmonary arterial pressure (mPAP) > 35 mmHg, in cirrhotic patients is usually considered an absolute contraindication to orthotopic liver transplantation (OLT) because of unacceptably high mortality. We present the case of successful OLT in a cirrhotic patient with a mPAP of 42 mmHg and a pulmonary vascular resistance (PVR) of 298 dyne . sec . cm(-5) preoperatively. He was treated with oral sildenafil (Viagra(R)) and inhaled iloprost (Ventavis(R)) for 45 days and then his mPAP and PVR were reduced to 33 mmHg and 206 dyne . sec . cm(-5) at the time of transplantation. During OLT, his mPAP was stable of 28?38 mmHg with the combined use of sildenafil via a nasogastric tube and iloprost via a nebulizer. His hemodynamic parameters were stable and significant postoperative bleeding was not noticed throughout his stay in the intensive care unit. Thereafter, he was transferred to general ward without any cardio-respiratory problems on 7th postoperative days.

Nocardia is a kind of aerobic Actinomycetes, gram positive organism that was acid-fast when stained with the modified Ziehl-Neelsen method. Nocardia is a soil saprophyte widely distributed throughout the world which usually introduced through the respiratory tract and may develop a disseminated infection, especially subcutaneous abscess and or central nervous system infection. Nocardiosis is an important opportunistic infection in immunosuppressed patients, lymphoma, sarcoidosis, and organ transplant patient. Sulfonamide therapy is known as a treatment of choice in nocardiosis. We report the two cases of nocardiosis in renal transplant recipient. Nocardia asteroides was isolated in our two cases. We treated sucessfully with Trimethoprim/Sulfamethoxazole(Bactrim).

Video capsule endoscopy (VCE) is an ingestible video camera that transmits high-quality images of the small intestinal mucosa. This makes the small intestine more readily accessible to physicians investigating the presence of small bowel disorders, such as Crohn's disease (CD). Although VCE is frequently performed in Korea, there are no evidence-based guidelines on the appropriate use of VCE in the diagnosis of CD. To provide accurate information and suggest correct testing approaches for small bowel diseases, the Korean Gut Image Study Group, part of the Korean Society of Gastrointestinal Endoscopy, developed guidelines on VCE. Teams were set up to develop guidelines on VCE. Four areas were selected: diagnosis of obscure gastrointestinal bleeding, small bowel preparation for VCE, diagnosis of CD, and diagnosis of small bowel tumors. Three key questions were selected regarding the role of VCE in CD. In preparing these guidelines, a systematic literature search, evaluation, selection, and meta-analysis were performed. After writing a draft of the guidelines, the opinions of various experts were solicited before producing the final document. These guidelines are expected to play a role in the diagnosis of CD. They will need to be updated as new data and evidence become available.

OBJECTIVES: Protein-calorie malnutrition has been shown to be prevalent among patients on long-term hemodialysis(HD) patients. And assessment of nutritional status of HD patients has assumed greater importance because of the association of protein- calorie malnutrition with increasing morbidity and mortality. So we observed the incidence and clinical effect of protein-calorie malnutrition, and we compared the indices of nutrition with dialysis adequacy utilizing urea kinetic modeling in HD patients. METHODS: We performed a cross-sectional study in which eight parameters, based on anthropometry, blood chemistry and subjective symptoms, were scored according to the degree of abnormalities in 48 HD patients. A malnutrition index was derived from these scores. We also performed comparative analysis to identify significant correlations of the indices of urea kinetic modeling with the other parameters of nutritional status. RESULTS: The malnutrition index classified 12(25 %) patients as normal, 28(58%) intermediately malnourished, and 8(17%) as severely malnourished. Malnutrition index showed a significant correlation with the body mass index(BMI), mid-arm circumference(MAC), mid-arm muscle area(MAMA), duration of HD, total lymphocyte count,trnsferrin. The malnutrition index also showed a significant correlation with renal creatinine clearance(Ccr), alkaline phosphatase. However, malnutrition index showed no meaningful correlation with TWR-Kt/V, TW-Kt/V, BUN, cholesterol,calcium, triglyceride. The value of Ccr was significantly lower in the severely malnourished and intermediately group than in the normal group. CONCLUSION: In assessing the nutritional status of HD patients, body weight, MAC, MAMA, duration of HD, total lymphocyte count, transferrin, alkaline phosphatase and Ccr were considered useful parameters. No meaningful relationships between TW-Kt/V and malnutrition index or between NPCR (normalized protein catabolic rate) and malnutrition index were found in this cross-sectional study. As the number of patients with longer duration of HD or negligible Ccr has increased in the malnourished patients, regular monitoring of these parameters, especially TWR-Kt/V and residual renal function may be helpful to assess dialysis adequacy to keep good nutritional status of each HD patient.

BACKGROUND/AIMS: Cytomegalovirus (CMV) reactivations are frequently observed in patients with active ulcerative colitis (UC), and ganciclovir therapy is effective in patients with steroid-refractory UC. This study aimed to determine the long-term outcomes of CMV reactivation and the long-term therapeutic efficacy of ganciclovir treatment. METHODS: This retrospective multicenter study included a cohort of 72 patients with moderate-to-severe UC who were evaluated for CMV reactivation at the time of their initial UC flare. Colectomy, disease relapse, and the recurrence rate of CMV reactivation were investigated. RESULTS: The mean duration of follow-up for the 72 patients was 43.16+/-19.78 months (range, 1 to 67 months). The cumulative colectomy (log-rank, p=0.025) and disease flare-up rates (log-rank, p=0.048) were significantly higher in the CMV-positive group. Of the 11 patients who were successfully treated with ganciclovir in the initial treatment, three patients (27.3%) experienced CMV reactivation, and six patients (54.5%) experienced poor outcomes, such as the need for colectomy or a steroid-dependent state. CONCLUSIONS: The patients who had CMV-reactivated UC showed poor outcomes at the long-term follow-up, and the long-term efficacy of ganciclovir therapy was marginal. Careful assessment is necessary for patients who exhibit evidence of CMV reactivation.
