Malnutrition is observed more frequently in patients with inflammatory bowel disease (IBD) than in the general population and associated with adverse clinical outcomes. This study aimed to review the current knowledge regarding the efficacy of dietary and nutritional intervention in IBD patients. Exclusive enteral nutrition might be inferior to corticosteroid treatment in adults with active Crohn’s disease (CD) but might even be superior considering the adverse effects of corticosteroid treatment in children. Total parenteral nutrition has no advantage over enteral nutrition, which is considered a more physiologic modality in organ function. Current guidelines do not yet recommend ω3-polyunsaturated fatty acid supplementation for the prevention and maintenance of remission in IBD patients. Dietary fiber supplementation could be effective in the relief of symptoms and maintenance of remission in ulcerative colitis (UC). Although vitamin D may be favorable to clinical course of IBD and bone density. Probiotic supplementation has proven to be effective in preventing and treating pouchitis for UC but is less effective in treating CD. Nutritional interventions not only correct nutritional deficiencies but also improve symptoms and clinical courses of the disease. Hence, nutritional approaches need to be developed to significantly evaluate the effectiveness of dietary interventions used to treat IBD.

BACKGROUND/AIMS: Consistently defining disease activity remains a critical challenge in the follow-up of patients with Crohn's disease (CD). We investigated the potential applicability of abdominal ultrasonography with color Doppler (USCD) analysis for the detection of morphological alterations and inflammatory activity in CD. METHODS: Forty-three patients with CD ileitis/ileocolitis were evaluated using USCD analysis with measurements obtained on the terminal ileum and right colon. Sonographic parameters included wall thickening, stricture, hyperemia, presence of intra-abdominal mass, and fistulas. Patients were evaluated for the clinical activity (Harvey-Bradshaw Index [HBI]), fecal calprotectin (FC) and C-reactive protein (CRP). The USCD performance was assessed using magnetic resonance enterography (MRE) as a criterion standard. RESULTS: Most measurements obtained with USCD matched the data generated with MRE; however, the agreement improved in clinically active patients where sensitivity, positive predictive value, and accuracy were >80%, considering wall thickening and hyperemia. Complications such as intestinal wall thickening, stricture formation, and hyperemia, were detected in the USCD analysis with moderate agreement with MRE. The best agreement with the USCD analysis was obtained in regard to FC, where the sensitivity, positive predictive value, and accuracy were >70%. The overall performance of USCD was superior to that of HBI, FC and CRP levels, particularly when considering thickening, stricture, and hyperemia parameters. CONCLUSIONS: USCD represents a practical noninvasive and low-cost tool for evaluating patients with ileal or ileocolonic disease, particularly in clinically active CD. Therefore, USCD might become a useful asset in the follow-up of patients with CD.

OBJECTIVETo evaluate the clinical outcomes of ileal D-pouch anal anastomosis in the treatment of ulcerative colitis (UC) and familial adenomatous polyposis (FAP).

METHODSClinical and follow-up data of 6 UC patients and 5 FAP patients undergoing proctocolectomy and D-ileum pouch anal anastomosis between October 2014 and March 2015 were retrospectively analyzed. End-to-side anastomosis was firstly performed in ileal cutting end and ileum, then side-to-side anastomosis was operated in closing amphi-loop to construct the D-ileum pouch.

RESULTSThe mean age of the patients was 42 years (range 18 to 61 years), 5 patients were female. The duration of surgery was (225±23) min, the operation time to D-ileum pouch was (18±4) min, the volume of D-ileum pouch was (175±15) ml, the blood loss was (110±30) ml. There was no procedure-related death, however rectum perforation occurred in 1 male UC patient during operation. The postoperative hospital stay was 8 to 11 days (mean 8.5 days). The follow-up period was 2 to 7 months (median 3 months). One female FAP patient suffered from anal anastomosis vagina fistula 21 days after operation. No pouch-related fistula, anastomosis or input loop stricture fecal incontinence, and severe pouchitis were recorded. The defecation frequency was 4 to 6 times per day (UC) and 3 to 5 times per day (FAP) 6 months after operation. No night-time fecal leakage was complained in those patients. Wexner incontinence score was 3±2 and GQLI was 114±11 one month after operation. Clinical outcome in the first month was excellent in 10 patients and good in 1 patient.

CONCLUSIONSAfter total colorectal resection for UC and FAP patients, application of D-ileum pouch can clear ileal stump of pouch and avoid the pouch-associated complications effectively.

BACKGROUND/AIMS: Pediatric inflammatory bowel disease (IBD) has been increasing worldwide. The characteristics of pediatric-onset IBD have mainly been reported in Western countries. We investigated the clinical characteristics of pediatric IBD in Korea and compared these with the data from the 5-year European multicenter study of children with new-onset IBD (EUROKIDS registry). METHODS: Children who were diagnosed with IBD between July 1987 and January 2012 were investigated at five Korean university hospitals. Their clinical characteristics were retrospectively evaluated by medical record review. The results were compared with the EUROKIDS data. RESULTS: A total of 30 children with Crohn's disease (CD) and 33 children with ulcerative colitis (UC) were enrolled. In comparison with the EUROKIDS group, Korean pediatric IBD patients showed a male predominance (86.7% vs 59.2%, p=0.002 in CD; 75.8% vs 50%, p=0.003 in UC). Korean pediatric CD patients had a higher prevalence of terminal ileal disease (36.7% vs 16.3%, p=0.004) and perianal disease (33.3% vs 8.2%, p<0.001) than patients in the EUROKIDS group. Korean pediatric UC patients had a higher prevalence of proctitis than patients in the EUROKIDS group. CONCLUSIONS: Our results suggest that the characteristics of Korean pediatric IBD patients and European pediatric IBD patients may be different.

BACKGROUND/AIMS: Diversion colitis is the inflammation of the excluded segment of the colon in patients undergoing ostomy. It has been suggested that a change in colonic flora may lead to colitis; however, direct evidence for this disease progression is lacking. The aim of this study was to evaluate the relationship between the severity of diversion colitis and the composition of colonic bacteria. METHODS: We used culture methods and polymerase chain reaction to analyze the colonic microflora of patients who underwent rectal cancer resection with or without diversion ileostomy. In the diversion group, we also evaluated the severity of colonoscopic and pathologic colitis before reversal. RESULTS: This study enrolled 48 patients: 26 in the diversion group and 22 in the control group. Significant differences were observed between the two groups in the levels of Staphylococcus (p=0.038), Enterococcus (p<0.001), Klebsiella (p<0.001), Pseudomonas (p=0.015), Lactobacillus (p=0.038), presence of anaerobes (p=0.019), and Bifidobacterium (p<0.001). A significant correlation between the severity of colitis and bacterial composition was only observed for Bifidobacterium (p=0.005, correlation coefficient=-0.531). CONCLUSIONS: The colonic microflora differed significantly between the diversion and control groups. Bifidobacterium was negatively correlated with the severity of diversion colitis.

Primary small intestinal lymphoma is relatively uncommon. Small bowel tumors are difficult to diagnose, because they are usually asymptomatic in the initial phase, and they are not easily detected by traditional methods of investigating the small intestine. This case shows a successfully detected and treated gastrointestinal bleeding from rare ileal mucosa-associated lymphoid tissue lymphoma, using double balloon endoscopy.

Crohn's disease is a chronic inflammatory disease that can involve the entire gastrointestinal tract. Several studies indicate that Crohn's patients with long disease duration have an increased risk of small bowel or colorectal cancer. In Korea, only a few cases of Crohn's disease-related small bowel or colorectal cancer have been reported. Here, we described 3 cases of colorectal cancer and 2 cases of small bowel cancer in patients with Crohn's disease. Among 5 patients, 3 had Crohn's disease-related lower gastrointestinal malignancy and the other 2 had sporadic lower gastrointestinal malignancies. Since the diagnosis of Crohn's disease-related lower gastrointestinal malignancy tends to be delayed, the development of malignancy should be considered in patients with long duration of Crohn's disease if patients have refractory symptoms despite intensive medical treatment. Surgical consultation should not be delayed.

OBJECTIVETo study the clinicopathologic features, immunohistochemical findings, differential diagnosis and prognosis of type II enteropathy-associated T-cell lymphoma (EATL).

METHODSFourteen cases of type II EATL encountered in Department of Pathology, Nanjing General Hospital were retrospectively reviewed. The clinical data, histologic features, immunohistochemical findings and follow-up information were analyzed, with literature review.

RESULTSThere were altogether 12 males and 2 females. The median age of patient was 49 years. The sites of involvement included jejunum (10 cases) and ileum/colon (4 cases). The patients often presented with an abdominal mass, abdominal pain, diarrhea and constitutional symptoms such as fever, night sweating and cachexia. There was no clinical evidence of gluten-sensitive enteropathy. Histologically, the lymphoma cells showed full-thickness infiltration of the intestinal wall. They contained round hyperchromatic nuclei and pale cytoplasm. The stroma was minimally inflamed, with or without associated coagulative necrosis. A remarkable finding was the presence of villous atrophy, cryptal hyperplasia and intraepithelial lymphocytosis. Immunohistochemical study showed that the tumor cells expressed CD3, CD43 and CD8 (14/14). Some of them were also positive for CD56 (11/14) and CD30 (2/14). The staining for CD4, CD20, CD79a and myeloperoxidase was negative. A high proliferation index was demonstrated by Ki-67 immunostain. In-situ hybridization for EBER was negative. Follow-up data were available in 9 cases. The duration of follow-up ranged from 6 months to 36 months. Seven patients died within 14 months.

CONCLUSIONSEATL is a rare type of lymphoma with intestinal involvement. Associated enteropathy is not demonstrated, in contrast to cases encountered in Nordic countries. A correct diagnosis requires evaluation of clinical manifestations, pathologic features and ancillary study results.
