| 1 | Wireless capsule endoscopy and proximal small bowel lesions in Crohn’s disease显示文摘AIM: To investigate the prevalence of proximal small bowel (SB) lesions detected by wireless capsule endoscopy (WCE) in Crohn's disease (CD). METHODS: WCE was performed in 64 patients: 32 with CD of the distal ileum, and 32 controls with iron-deficiency anemia (IDA) or diarrhea. WCE was performed using the Given SB-WCE, followed by small intestine contrast ultrasonography (SICUS). Findings compatible with CD by using WCE included erosions, aphthoid or deep ulcers, and strictures/stenosis. RESULTS: WCE detected proximal SB lesions in 16/32 (50%) patients (14 aphthoid ulcers, 2 deep ulcers, one stricture), which appeared not to be related to clinical parameters [epigastric pain, age, smoking, non-steroidalanti-inflammatory drugs (NSAIDs), IDA]. Among patients with proximal SB lesions, 6 (37%) were smokers, 3 (19%) NSAID users, 3 (19%) had epigastric pain and 4 (25%) had IDA. SICUS detected proximal SB lesions in 3/32 patients (19%) also showing lesions with WCE. No correlations were observed between proximal SB lesions assessed by WCE or by SICUS (χ2 = 1.5, P = 0.2). CONCLUSION: The use of WCE allows the detection of previously unknown upper SB lesions in a high proportion of patients with a previous diagnosis of CD involving the distal ileum. | Carmelina Petruzziello Sara Onali Emma Calabrese Francesca Zorzi Marta Ascolani Giovanna Condino Elisabetta Lolli Paola Naccarato Francesco Pallone Livia Biancone | 2010 | World Journal of Gastroenterology2010，16，26： | 7 |
| 2 | Small intestine contrast ultrasonography vs computed tomography enteroclysis for assessing ileal Crohn's disease显示文摘AIM:To compare computed tomography enteroclysis(CTE) vs small intestine contrast ultrasonography(SICUS) for assessing small bowel lesions in Crohn's disease(CD),when using surgical pathology as gold standard.METHODS:From January 2007 to July 2008,15 eligible patients undergoing elective resection of the distal ileum and coecum(or right colon) were prospectively enrolled.All patients were under follow-up.The study population included 6 males and 9 females,with a median age of 44 years(range:18-80 years).Inclusion criteria:(1) certain diagnosis of small bowel requiring elective ileo-colonic resection;(2) age between 18-80 years;(3) elective surgery in our Surgical Unit;and(4) written informed consent.SICUS and CTE were performed ≤ 3 mo before surgery,followed by surgical pathology.The following small bowel lesions were blindly reported by one sonologist,radiologist,surgeon and histolopathologist:disease site,extent,strictures,abscesses,fistulae,small bowel dilation.Comparison between findings at SICUS,CTE,surgical specimens and histological examination was made by assessing the specificity,sensitivity and accuracy of each technique,when using surgical findings as gold standard.RESULTS:Among the 15 patients enrolled,CTE was not feasible in 2 patients,due to urgent surgery in one patients and to low compliance in the second patient,refusing to perform CTE due to the discomfort related to the naso-jejunal tube.The analysis for comparing CTE vs SICUS findings was therefore performed in 13 out of the 15 CD patients enrolled.Differently from CTE,SICUS was feasible in all the 15 patients enrolled.No complications were observed when using SICUS or CTE.Surgical pathology findings in the tested population included:small bowel stricture in 13 patients,small bowel dilation above ileal stricture in 10 patients,abdominal abscesses in 2 patients,enteric fistulae in 5 patients,lymphnodes enlargement(> 1 cm) in 7 patients and mesenteric enlargement in 9 patients.In order to compare findings by using SICUS,CTE,histology and surgery,characteristics of the small bowel lesions observed in CD each patient were blindly reported in the same form by one gastroenterologistsonologist,radiologist,surgeon and anatomopathologist.At surgery,lesions related to CD were detected in the distal ileum in all 13 patients,also visualized by both SICUS and CTE in all 13 patients.Ileal lesions > 10 cm length were detected at surgery in all the 13 CD patients,confirmed by SICUS and CTE in the same 12 out of the 13 patients.When using surgical findings as a gold standard,SICUS and CTE showed the exactly same sensitivity,specificity and accuracy for detecting the presence of small bowel fistulae(accuracy 77% for both) and abscesses(accuracy 85% for both).In the tested CD population,SICUS and CTE were also quite comparable in terms of accuracy for detecting the presence of small bowel strictures(92% vs 100%),small bowel fistulae(77% for both) and small bowel dilation(85% vs 82%).CONCLUSION:In our study population,CTE and the non-invasive and radiation-free SICUS showed a comparable high accuracy for assessing small bowel lesions in CD. | Sara Onali Emma Calabrese Carmelina Petruzziello Francesca Zorzi Giuseppe Sica Roberto Fiori Marta Ascolani Elisabetta Lolli Giovanna Condino Giampiero Palmieri Giovanni Simonetti Francesco Pallone Livia Biancone | 2012 | World Journal of Gastroenterology2012，18，42： | 5 |

| 9 | Ileal lesions in patients with ulcerative colitis after ileo-rectal anastomosis:Relationship with colonic metaplasia显示文摘AIM:To assess whether in ulcerative colitis (UC) patients with ileo-rectal anastomosis (IRA), ileal lesions may develop in the neo-terminal-ileum and their possible relation with phenotypic changes towards colonic epithelium. METHODS: A total of 19 patients with IRA under regular follow up were enrolled, including 11 UC and 8 controls (6 Crohn’s disease, CD; 1 familial adenomatous polyposis, FAP; 1 colon cancer, colon K). Ileal lesions were identifi ed by ileoscopy with biopsies taken from the ileum (involved and uninvolved) and from the rectal stump. Staining included HE and immunohistochemistry using monoclonal antibodies against colonic epithelial protein CEP (Das-1) and human tropomyosin isoform 5, hTM5 (CG3). Possible relation between development of colonic metaplasia and ileal lesions was investigated.RESULTS: Stenosing adenocarcinoma of the rectal stump was detected in 1 UC patient. The neo-terminal ileum was therefore investigated in 10/11 UC patients. Ileal ulcers were detected in 7/10 UC, associated with colonic metaplasia in 4/7 (57.1%) and Das-1 and CG3 reactivity in 3/4 UC. In controls, recurrence occurred in 4/6 CD, associated with colonic metaplasia in 3/4 and reactivity with Das-1 and CG3 in 2/3. CONCLUSION: Present fi ndings suggest that in UC, ileal lesions associated with changes towards colonic epithelium may develop also after IRA. Changes of the ileal content after colectomy may contribute to the development of colonic metaplasia, leading to ileal lesions both in the pouch and in the neo-terminal ileum after IRA. | Livia Biancone Emma Calabrese Giampiero Palmieri Carmelina Petruzziello Sara Onali Giuseppe Sigismondo Sica Marta Cossignani Giovanna Condino Kiron Moy Das Francesco Pallone | 2008 | World Journal of Gastroenterology2008，14，34： | 1 |
