Abstract
BACKGROUND Narrow-band imaging (NBI) is as sensitive as Lugol chromoendoscopy to detect esophageal squamous cell carcinoma (SCC) but its specificity, which appears higher than that of Lugol chromoendoscopy in expert centers, remains to be established in general practice. This study aimed to prove the superiority of NBI specificity over Lugol chromoendoscopy in the detection of esophageal SCC and high grade dysplasia (HGD) in current general practice (including tertiary care centers, local hospitals, and private clinics). METHODS This prospective randomized multicenter trial included consecutive patients with previous or current SCC of the upper aerodigestive tract who were scheduled for gastroscopy. Patients were randomly allocated to either the Lugol or NBI group. In the Lugol group, examination with white light and Lugol chromoendoscopy were successively performed. In the NBI group, NBI examination was performed after white-light endoscopy. We compared the diagnostic characteristics of NBI and Lugol chromoendoscopy in a per-patient analysis. RESULTS 334 patients with history of SCC were included and analyzed (intention-to-treat) from 15 French institutions between March 2011 and December 2015. In per-patient analysis, sensitivity, specificity, positive and negative likelihood values were 100 %, 66.0 %, 21.2 %, and 100 %, respectively, for Lugol chromoendoscopy vs. 100 %, 79.9 %, 37.5 %, and 100 %, respectively, for NBI. Specificity was greater with NBI than with Lugol (P = 0.002). CONCLUSIONS As previously demonstrated in expert centers, NBI was more specific than Lugol in current gastroenterology practice for the detection of early SCC, but combined approaches with both NBI and Lugol could improve the detection of squamous neoplasia.

Abstract
INTRODUCTION Most studies of elderly-onset Crohn's disease [CD; diagnosed in patients aged 60 or over] have described a mild course. However, data on the natural history of perianal fistulising CD [pfCD] in this population are scarce. In a population-based cohort study, we described the prevalence, natural history, and treatment of pfCD in patients with elderly-onset CD vs patients with paediatric-onset CD. METHOD All patients diagnosed with CD at or after the age of 60 between 1988 and 2006, were included [n = 372]. Logistic regression, Cox models, and a nested case-control method were used to identify factors associated with pfCD. RESULTS A total of 34 elderly patients [9% of the 372] had pfCD at diagnosis. After a median follow-up of 6 years (interquartile range [IQR]: 3; 10), 59 patients [16%] had pfCD; the same prevalence [16%] was observed in paediatric-onset patients. At last follow-up, anal incontinence was more frequent in elderly patients with pfCD than in elderly patients without pfCD [22% vs 4%, respectively; p < 10-4]. Rectal CD at diagnosis was associated with pfCD: hazard ratio (95% confidence interval [CI] = 2.8 [1.6-5.0]). Although 37% of the patients received immunosuppressants and 17% received anti-tumour necrosis factor agents, 24% [14 out of 59] had a definitive stoma at last follow-up. CONCLUSION During the first 6 years of disease, the prevalence of pfCD was similar in elderly and paediatric patients. Rectal involvement was associated with the appearance of pfCD in elderly-onset patients. Around a quarter of patients with elderly-onset CD will have a stoma. Our results suggest that treatment with biologics should be evaluated in these patients.

Abstract
OBJECTIVES Few data are available to describe the changes in incidence of pediatric-onset inflammatory bowel disease (IBD). The aim of this study was to describe changes in incidence and phenotypic presentation of pediatric-onset IBD in northern France during a 24-year period. METHODS Pediatric-onset IBD (<17 years) was issued from a population-based IBD study in France between 1988 and 2011. Age groups and digestive location were defined according to the Paris classification. RESULTS 1,350 incident cases were recorded (8.3% of all IBD) including 990 Crohn's disease (CD), 326 ulcerative colitis (UC) and 34 IBD unclassified (IBDU). Median age at diagnosis was similar in CD (14.4 years (Q1=11.8-Q3=16.0)) and UC (14.0 years (11.0-16.0)) and did not change over time. There were significantly more males with CD (females/males=0.82) than UC (females/males=1.25) (P=0.0042). Median time between onset of symptoms and IBD diagnosis was consistently 3 months (1-6). Mean incidence was 4.4/105 for IBD overall (3.2 for CD, 1.1 for UC and 0.1 for IBDU). From 1988-1990 to 2009-2011, a dramatic increase in incidences of both CD and UC were observed in adolescents (10-16 years): for CD from 4.2 to 9.5/105 (+126%; P<0.001) and for UC, from 1.6 to 4.1/105 (+156%; P<0.001). No modification in age or location at diagnosis was observed in either CD or UC. CONCLUSIONS In this population-based study, CD and UC incidences increased dramatically in adolescents across a 24-year span, suggesting that one or more strong environmental factors may predispose this population to IBD.

Abstract
BACKGROUND AND AIMS Data on extra-intestinal manifestations [EIM] and their impact on the disease course of ulcerative colitis [UC] in population-based cohorts are scarce, particularly in paediatric- and elderly-onset UC patients. The aims of this population-based study were to assess: 1] the occurrence of EIM in paediatric- and elderly-onset UC; 2] the factors associated with EIM; and 3] their impact on long-term disease outcome. METHODS Paediatric-onset [< 17 years at diagnosis] and elderly-onset UC patients [> 60 years at diagnosis] from a French prospective population-based registry [EPIMAD] were included. Data on EIM and other clinical factors at diagnosis and at maximal follow-up were collected. RESULTS In all, 158 paediatric- and 470 elderly-onset patients were included [median age at diagnosis 14.5 and 68.8 years, median follow-up 11.2 and 6.2 years, respectively]. EIM occurred in 8.9% of childhood- and 3% of elderly-onset patients at diagnosis and in 16.7% and 2.2% of individuals during follow-up [p < 0.01], respectively. The most frequent EIM was joint involvement [15.8% of paediatric onset and 2.6% of elderly-onset]. Presence of EIM at diagnosis was associated with more severe disease course [need for immunosuppressants or biologic therapy or colectomy] in both paediatric- and elderly-onset UC (hazard ratio [HR] = 2.0, 95% confidence interval [CI]: 1.0-4.2; and HR = 2.8, 0.9-7.9, respectively). Extensive colitis was another independent risk factor in both age groups. CONCLUSIONS Elderly-onset UC patients had lower risk of EIM either at diagnosis or during follow-up than paediatric-onset individuals. EIM at diagnosis predicted more severe disease outcome, including need for immunosuppressive or biologic therapy or surgery, in both paediatric- and elderly-onset UC.

Abstract
Direct electron transfer (DET) to proteins is of considerable interest for the development of biosensors and bioelectrocatalysts. While protein structure is mainly used as a method of attaching the protein to the electrode surface, we employed bioinformatics analysis to predict the suitable orientation of the enzymes to promote DET. Structure similarity and secondary structure prediction were combined underlying localized amino-acids able to direct one of the enzyme's electron relays toward the electrode surface by creating a suitable bioelectrocatalytic nanostructure. The electro-polymerization of pyrene pyrrole onto a fluorine-doped tin oxide (FTO) electrode allowed the targeted orientation of the formate dehydrogenase enzyme from Rhodobacter capsulatus (RcFDH) by means of hydrophobic interactions. Its electron relays were directed to the FTO surface, thus promoting DET. The reduction of nicotinamide adenine dinucleotide (NAD(+)) generating a maximum current density of 1μAcm(-2) with 10mM NAD(+) leads to a turnover number of 0.09electron/s/molRcFDH. This work represents a practical approach to evaluate electrode surface modification strategies in order to create valuable bioelectrocatalysts.

Abstract
Self-expandable plastic stents are currently recommended for refractory benign esophageal strictures but they show disappointing results in terms of migration and long-term efficacy. We report here our experience in the management of benign esophageal strictures with partially covered (PCSEMS) and fully covered self-expandable metal stents (FCSEMS). We performed a retrospective analysis of self-expandable metal stent (SEMS) placements for benign esophageal strictures from 1998 to 2011 in Rouen University Hospital. Twenty-two patients (15 men, 7 women) attempted 40 esophageal SEMS placements (17 PCSEMS, 23 FCSEMS) during this period. All technical complications were migrations. Migration was noted after 3/17 PCSEMS (17.6%) and 4/23 FCSEMS placement (17.4%, P = ns). Clinical complications occurred after 6/17 PCSEMS and 2/23 FCSEMS placements (35.3% vs. 8.7%, P = 0.053). PCSEMS caused two major complications (fistulae) whereas FCSEMS did not cause any major complication (11.7% vs. 0%). Mean dysphagia score was significantly lower after SEMS placement (1.68 vs. 3.08, P < 0.001) with similar results for PCSEMS and FCSEMS. Stent placement resulted in long-term clinical success for 23.5% of PCSEMS and 34.7% of FCSEMS (P = 0.0505). FCSEMS provide satisfying clinical success rate with an acceptable complication rate and they could constitute a relevant therapeutic option in the management of benign esophageal strictures.

Abstract
BACKGROUND The diagnosis of acute diverticulitis is mainly based on clinical, biological and computed tomography (CT)-scan findings. Elective colonoscopy is recommended after medical treatment, to rule out another diagnosis and to detect associated conditions; however, the relevance of this recommendation has been questioned. PATIENTS AND METHODS Between January 2005 and December 2011, we retrospectively identified in three referral centers the consecutive patients whom underwent a colonoscopy after the medical treatment of a CT scan-proven acute diverticulitis episode. We excluded from the analysis patients with haematochezia or recent change in bowel habits. Sex and age-matched asymptomatic patients undergoing a screening colonoscopy were chosen as a control group. We collected and compared the results of colonoscopy and histological findings in both groups. RESULTS We matched 404 patients whom underwent a colonoscopy after an episode of acute diverticulitis with 404 control patients. Their mean age was 60.9 years, with 59% being women. Colorectal adenoma, advanced adenoma and cancer detection rates in acute diverticulitis patients were 12.1%, 2.7% and 0.25%, respectively; versus 14.6% (p = 0.35), 6.7% (p = 0.01) and 0.25% respectively, in control patients. CONCLUSIONS Diagnosis rates for adenomas and for colorectal cancer during a colonoscopy scheduled after acute diverticulitis were similar than those of control patients undergoing a screening colonoscopy, while the detection rate of advanced adenomas was lower. We suggest that colonoscopy should be indicated only in selected patients, i.e. those presenting with reasonable doubt on initial CT-scan, those with alarm symptoms, and those with identified risk factors for colorectal cancer.

BACKGROUND To date, there are no large studies on videocapsule endoscopy in systemic sclerosis (SSc). Consequently, the prevalence and features of gastrointestinal mucosal abnormalities in SSc have not been determined. AIMS To determine both prevalence and characteristics of gastrointestinal mucosal abnormalities in unselected patients with SSc, using videocapsule endoscopy. To predict which SSc patients are at risk of developing potentially bleeding gastrointestinal vascular mucosal abnormalities. METHODS Videocapsule endoscopy was performed on 50 patients with SSc. RESULTS Prevalence of gastrointestinal mucosal abnormalities was 52%. Potentially bleeding vascular mucosal lesions were predominant, including: watermelon stomach (34.6%), gastric and/or small intestinal telangiectasia (26.9%) and gastric and/or small intestinal angiodysplasia (38.5%). SSc patients with gastrointestinal vascular mucosal lesions more often exhibited: limited cutaneous SSc (P = 0.06), digital ulcers (P = 0.05), higher score of nailfold videocapillaroscopy (P = 0.0009), anaemia (P = 0.02), lower levels of ferritin (P < 0.0001) and anti-centromere antibody. CONCLUSIONS Our study identifies a high frequency of gastrointestinal mucosal abnormalities in SSc, with a marked predominance of vascular mucosal damage. Furthermore, our study shows a strong correlation between gastrointestinal vascular mucosal lesions and presence of severe extra-digestive vasculopathy (digital ulcers and higher nailfold videocapillaroscopy scores). This latter supports the theory that SSc-related diffuse vasculopathy is responsible for both cutaneous and digestive vascular lesions. Therefore, we suggest that nailfold videocapillaroscopy may be a helpful test for managing SSc patients. In fact, nailfold videocapillaroscopy score should be calculated routinely, as it may result in identification of SSc patients at higher risk of developing potentially bleeding gastrointestinal vascular mucosal lesions.

Abstract
157 Background: For pancreatic tumor, guidelines recommend pancreatic cytology examination by EUS-FNA as the first diagnostic procedure in unresectable patients. Detecting CTCs in blood could play the role of a “liquid biopsy”. The usefulness of CTC detection in the clinical management of these patients has not been established yet. Here, we aimed to prospectively evaluate the accuracy of a diagnostic method based on CTC detection. Methods: All patients referred from January 2011 to March 2012 for EUS-FNA procedure in a context of pancreatic solid tumor diagnosis were prospectively enrolled after their consent. Prior EUS-FNA procedure a sample of peripheral blood was collected. CTCs were analyzed using the ScreenCell method. Cells were considered as tumoral if they met these morphological criteria: nuclear diameter >14 µ, anisocytosis, anisocaryosis, nuclear membrane irregularities, large nucleolus, clots of tumoral cells with platelets and fibrin. All analysis was performed by a pathologist blinded to the EUS-FNA results. The diagnosis of pancreatic adenocarcinoma was defined either by pathological evidence based on FNA or surgical specimen, or by clinical outcome with metastatic evolution and CA19.9 serum level rather than 10 fold normal value. Results: A total of 40 patients were included. A pancreatic adenocarcinoma was confirmed in 27/40 patients (68.3%). In 21 of the 27 patients, pathological proof of adenocarcinoma was obtained by EUS-FNA. For the diagnosis of adenocarcinoma, sensitivity and specificity of EUS-FNA were 77.8% and 100% respectively. The diagnostic accuracy of FNA was 85%. CTC detection was positive in 15 patients. Sensitivity and specificity were 55.5% (CI95% [40.1%; 70.9%]) and 100% (CI95% [75%; 100%]) respectively. The diagnostic accuracy of CTC was 70%. Metastatic statuses, lymph node involvement, vascular invasion, size of tumor and CA19.9 serum level were not statistically associated with CTC detection. Conclusions: We suggest that CTC detection be applied as first-line procedure before EUS-FNA in the strategy of pancreatic tumor diagnosis. With the implementation of this blood test on a routine basis, approximately one half of these patients could avoid invasive EUS-FNA procedure.

Abstract
BACKGROUND & AIMS Capsule enteroscopy (CE) is the best noninvasive tool to explore the entire small bowel of patients with obscure gastrointestinal bleeding (OGIB); it has a diagnostic yield of 40%-80%. However, little is known about the factors associated with a diagnosis of OGIB by CE. METHODS We analyzed data from 911 consecutive patients who underwent CE for OGIB from January 2004 to January 2010. Results from upper and lower gastrointestinal endoscopy examinations were negative in all patients. CE findings were recorded. Features of patients that were associated with diagnosis of OGIB by CE were identified by using logistic regression. RESULTS Based on CE, 509 patients (56%) had a confirmed lesion responsible for the OGIB: 203 had disease of the small bowel (22%), 88 had ulcerations (10%), 70 had tumors (8%), 24 had varices (2%), 6 had diverticula (0.5%), and 118 had what appeared to be bleeding lesions of the esophagus or stomach (10.6%) or colon (2%). Factors independently associated with a diagnosis of OGIB by CE were age >60 years (odds ratio [OR], 1.2), male sex, history of overt bleeding (OR, 3.8), and current hospitalization (OR, 1.4). Women were less likely to be diagnosed with OGIB by CE (OR, 0.7). CONCLUSIONS A history of overt bleeding is the factor most strongly associated with a diagnosis of OGIB by CE. Male sex, age >60 years, and inpatient status were also independent predictors of positive diagnosis by CE.

Abstract
Background The irritable bowel syndrome (IBS) is a functional gastrointestinal disorder whose
pathogenesis is not completely understood. Its high prevalence and the considerable
effects on quality of life make IBS a disease with high social cost. Recent studies
suggest that low grade mucosal immune activation, increased intestinal permeability and
the altered host-microbiota interactions that modulate innate immune response,
contribute to the pathophysiology of IBS. However, the understanding of the precise
molecular pathophysiology remains largely unknown. Methodology and Findings In this study our objective was to evaluate the TLR expression as a key player in the
innate immune response, in the colonic mucosa of IBS patients classified into the three
main subtypes (with constipation, with diarrhea or mixed). TLR2 and TLR4 mRNA expression
was assessed by real time RT-PCR while TLRs protein expression in intestinal epithelial
cells was specifically assessed by flow cytometry and immunofluorescence. Mucosal
inflammatory cytokine production was investigated by the multiplex technology. Here we
report that the IBS-Mixed subgroup displayed a significant up-regulation of TLR2 and
TLR4 in the colonic mucosa. Furthermore, these expressions were localized in the
epithelial cells, opening new perspectives for a potential role of epithelial cells in
host-immune interactions in IBS. In addition, the increased TLR expression in IBS-M
patients elicited intracellular signaling pathways resulting in increased expression of
the mucosal proinflammatory cytokines IL-8 and IL1β. Conclusions Our results provide the first evidence of differential expression of TLR in IBS
patients according to the disease subtype. These results offer further support that
microflora plays a central role in the complex pathophysiology of IBS providing novel
pharmacological targets for this chronic gastrointestinal disorder according to bowel
habits.

Abstract
BACKGROUND AND STUDY AIMS Patients with obscure-overt gastrointestinal bleeding (OOGIB) are defined by overt hemorrhage and negative upper and lower endoscopy findings. At present, the place of emergency capsule enteroscopy in patients with severe OOGIB is unknown. The aim of this study was to assess the diagnostic yield and the impact of emergency capsule enteroscopy on further management in patients with severe OOGIB. PATIENTS AND METHODS Between 2003 and 2010, we retrospectively included all patients with severe OOGIB who underwent emergency capsule enteroscopy in the 24-48 h following negative urgent upper and lower endoscopy. Severe OOGIB was defined by ongoing bleeding with hemodynamic instability and/or the need for significant red blood cell transfusion. RESULTS Out of 5744 patients hospitalized in our Gastrointestinal Bleeding Unit, 55 (1%) presented with severe OOGIB and underwent emergency capsule enteroscopy. Capsule enteroscopy showed blood in 41 patients (75%) and lesions in 37 patients (67%). Findings included small bowel angiodysplasia in 19 patients (35%), ulcers in 7 (13%), tumors in 5 (9%), small-bowel varices in 2 (3%), cecum angiodysplasia in 4 (7%), fresh blood in small bowel without identified lesion in 12 (22%). Specific diagnostic and therapeutic procedures were undertaken in 78 % of patients. Further management included endoscopy (54%), surgery (22%), and radiology (2%). CONCLUSIONS Emergency capsule enteroscopy identified bleeding lesions in 67 % of patients with severe OOGIB. Emergency capsule enteroscopy seems to be a promising diagnostic tool with a subsequent impact on clinical management in patients with severe OOGIB.

Abstract
To date, Lugol chromo-endoscopy is the reference technique to detect an esophageal neoplasia in patients with prior esophageal squamous-cell carcinoma (ESCC), but is not easy to perform without general anesthesia, which can limit its use in routine practice. The objective of this study were to compare the accuracy of white light, narrow band imaging (NBI), and Lugol to detect esophageal neoplasia in patients with a history of cured ESCC, in a prospective study. Thirty patients were prospectively included between June 2006 and June 2009. They all had a history of cured ESCC. Esophageal mucosa was examined first using white light, second NBI, and third after Lugol staining. Histology was obtained in all abnormalities detected by white light, NBI, and/or Lugol. Five neoplastic lesions in five different patients were identified at histology, four cancers, and one high-grade dysplasia. NBI and Lugol both detected all esophageal neoplastic lesions, whereas white light detected the four cancers but missed the high-grade dysplasia. In this feasibility study, NBI and Lugol both detected all identified esophageal neoplasia in very high-risk patients of ESCC. This result suggests that NBI could be used instead of Lugol to detect an esophageal neoplasia in patients with high risk of ESCC, but needs to be confirmed in a larger study.

Abstract
ABSTRACTStudies of the local segmental relaxation in rubbery networks reveal a variety of behaviors. In experiments on networks with labeled junctions, whereby the motion of the crosslink site is specifically monitored, the segmental relaxation function broadens, accompanied by a larger activation energy, in a manner well-described by the coupling model of relaxation. The more usual experiment simply measures bulk relaxation, without discriminating among different relaxing entities. For networks, crosslinking introduces a distribution of relaxation behaviors, related to the proximity of a moiety to the junctions. The resulting inhomogeneously broadened relaxation function is difficult to analyze; nevertheless, a heightened sensitivity to temperature (larger activation energy) is exhibited, from which inferences can be made regarding the shape of the relaxation function. Finally, the segmental relaxation of highly crosslinked microgels is ostensibly homogeneous. Interestingly, however, the inverse correlation between the stretch exponent, β, and the activation energy, observed quantitatively in conventional networks, is violated by the microgels.

Abstract
BACKGROUND Only limited data has been reported so far regarding oesophageal cancer (EC) in elderly patients. The aim of the study is to identify the baseline parameters that influenced therapeutic decision. METHODS All consecutive patients 70 years or older being treated for EC were retrospectively analyzed. Patients without visceral metastasis were divided into two groups: treatment with curative intent (chemoradiotherapy, surgery, radiotherapy, mucosectomy or photodynamic therapy) or best supportive care (BSC). Patients with metastasis were divided into two groups: palliative treatment (chemotherapy, chemoradiotherapy or radiotherapy) or BSC. RESULTS Two hundred and eighty-two patients were studied. Mean age was 76.5 ± 5.5 years and 22.4% of patients had visceral metastasis. In patients without visceral metastasis (n = 220) the majority had treatment with curative intent (n = 151) whereas in patients with metastasis (n = 62) the majority had BSC (n = 32). Severe adverse events (≥ grade 3) were observed in only 17% of the patients. Patients without specific carcinologic treatment were older, had more weight loss, worse WHO performance status and Charlson score in multivariate analysis. DISCUSSION Our results suggest that elderly patients with an EC could benefit from cancer treatment without major toxicities. Weight loss, WHO performance status and the Charlson score could be used to select the appropriate treatment in an elderly patient.

Abstract
BACKGROUND Capsule endoscopy (CE) is an effective method for investigating the small bowel, especially in cases of obscure gastrointestinal bleeding (OGIB), although the long-term outcome of patients with a negative CE is generally not known. PATIENTS AND METHODS For 49 patients with OGIB and a negative CE, their referring physicians filled out a follow-up questionnaire to assess bleeding recurrence and any repeat investigations after negative video capsule endoscopy (VCE). RESULTS A minimum follow-up duration of one year (median: 15.9 months) was available for 35 patients with an overall rebleeding rate of 23% (n=8). Of these eight patients, four women presented with recurrence prior to new investigations. In the four remaining patients, repeat endoscopy work-ups after negative CE were performed and revealed previously missed lesions with bleeding potential, mainly in the stomach. Overall, 13 patients, with or without rebleeding, had repeat endoscopy work-ups after a negative CE, leading to a definitive diagnosis in nine patients, with lesions located in the stomach and colon in eight of them. CONCLUSION Patients with OGIB and a negative CE had a low rate of rebleeding. This study highlights the importance of the initial endoscopy work-up, and suggests that CE be proposed after a minimum of two gastroscopies and one complete colonoscopy.

Abstract
OBJECTIVES Proteasome-mediated protein degradation may contribute to the regulation of intestinal inflammation. At the same time, low-grade inflammation and increased intestinal permeability seem to be involved in the pathophysiology of irritable bowel syndrome (IBS). Thus, we aimed to evaluate proteasome composition and activities in colonic mucosa of IBS patients and its putative pathogenic role. METHODS Proteasome activities and proteasome subunit expression were measured in colonic mucosa of IBS, Crohn's disease (CD), and control patients by fluorometric assays and western blot, respectively. Expression of inhibitor of kappa B factor (IkappaB alpha) and occludin, a tight junction protein, was also evaluated in colonic biopsies. The degradation of recombinant occludin incubated with protein extracts from colonic mucosa was evaluated in the presence or absence of proteasome inhibitor, MG132. RESULTS Proteasome trypsin-like activity was increased in IBS patients compared with CD and controls, whereas chymotrypsin-like activity was upregulated in CD patients only. Caspase-like activity was reduced both in IBS and CD patients. IkappaB alpha expression was similar between IBS and controls. In contrast, occludin expression was lower in IBS than in controls, but occludin mRNA level was similar. Protein extracts from IBS patients but not from controls degraded recombinant occludin (20% over 160 min), which was blocked by MG132. Although mast cell number was increased in IBS patients, no correlation was found between this number and proteasome alterations. CONCLUSIONS Our study shows that proteasome alterations are present in the colonic mucosa of IBS patients and may contribute to the pathophysiology of IBS by increasing occludin degradation.

Abstract
Mallory-Weiss syndrome is relatively common and is involved in 3 to 10% of cases of upper gastrointestinal bleeding. Most of the time, the hemorrhage is mild and stops spontaneously. Clinical suspicion requires confirmation by an upper gastrointestinal endoscopy, which must be performed rapidly after the first hematemesis. Mallory-Weiss syndrome is diagnosed when it shows a longitudinal mucosal tear at the esophagogastric junction. Patients with active bleeding or signs of recent bleeding at endoscopy need immediate endoscopic treatment for hemostasis. Band ligation seems to be the most efficient procedure for primary hemostasis and for preventing recurrent bleeding. The use of proton pump inhibitors and antiemetics seems logical in all cases, although nothing in the literature demonstrates their efficacy.

Abstract
BACKGROUND Mallory-Weiss syndrome (MWS) with active bleeding at endoscopy may require endoscopic haemostasis the modalities of which are not well-defined. AIM To compare the efficacy of endoscopic band ligation vs. hemoclip plus epinephrine (adrenaline) in bleeding MWS. METHODS From 2001 to 2008, 218 consecutive patients with a MWS at endoscopy were hospitalized in our Gastrointestinal Bleeding Unit. In 56 patients (26%), an endoscopic haemostasis was required because of active bleeding. Band ligation was performed in 29 patients (Banding group), while hemoclip application plus epinephrine injection was performed in 27 patients (H&E group). Treatment efficacy and early recurrent bleeding were retrospectively compared between the two groups. RESULTS Primary endoscopic haemostasis was achieved in all patients. Recurrent bleeding occurred in 0% in Banding group vs. 18% in H&E group (P = 0.02). The use of hemoclips plus epinephrine (OR = 3; 95% CI = 1.15-15.8) and active bleeding at endoscopy (OR = 1.9; 95% CI = 1.04-5.2) were independent predictive factors of early recurrent bleeding. CONCLUSIONS Haemostasis by hemoclips plus epinephrine was an independent predictive factor of rebleeding. This result suggests that band ligation could be the first choice endoscopic treatment for bleeding MWS, but requires further prospective assessment.

Abstract
Glutamine (Gln) and arginine (Arg) are conditionally essential amino acids with immunomodulatory properties. The aim of the study was to assess the effects of Gln and Arg alone or in combination on cytokine release by cultured colonic biopsies from patients with active Crohn's disease (CD). Ten consecutive patients [mean (range) age 26 (18-39) y] with active colonic CD (mean CD activity index: 383.7 +/- 129.8) were prospectively included in the study. Eight colonic biopsies were obtained via a colonoscopy and incubated during 18 h with low (physiological) or high (pharmacological) doses of Arg (0.1 or 2 mmol/L designated as Arg(low) or Arg(high), respectively) and Gln (0.6 or 10 mmol/L designated as Gln(low) or Gln(high), respectively). The concentrations of cytokines [interleukin (IL)-4, IL-10, IL-8, IL-6, tumor necrosis factor-alpha (TNFalpha), IL-1beta, interferon-gamma) were assessed by ELISA, and nitric oxide (NO) production was evaluated by Griess assay. Nuclear factor (NF)-kappaB p65 subunit, inhibitor of NFkappaB-alpha, and p38 mitogen-activated protein kinase (MAPK) were assessed by immunoblotting. Arg(high)/Gln(high) decreased the production of TNFalpha, IL-1beta, IL-8, and IL-6 (each P < 0.01). Arg(low)/Gln(high) decreased IL-6 and IL-8 production (both P < 0.01), whereas Arg(high)/Gln(low) did not affect cytokine and NO production. Arg(low)/Gln(high) and Arg(high)/Gln(high) decreased NF-kappaB p65 subunit expression, whereas p38 MAPK was decreased only by Arg(high)/Gln(high). Combined pharmacological doses of Arg and Gln decreased TNFalpha and the main proinflammatory cytokines release in active colonic CD biopsies via NF-kappaB and p38 MAPK pathways. These results could be the basis of prospective studies evaluating the effects of enteral supply of combined Arg and Gln during active CD.

Abstract
INTRODUCTION Photodynamic therapy (PDT) is a therapeutic option in patients with a superficial esophageal cancer. Recently, PDT was shown to be effective as a salvage therapy for a local recurrence after chemoradiotherapy (CRT). AIM To compare retrospectively the results and the complications rate of PDT between consecutive patients treated in primary intent for a superficial esophageal cancer versus patients treated by PDT for a local recurrence after CRT. METHODS Between 1999 and 2007 in a single center, 40 consecutive patients were treated by PDT for a superficial esophageal cancer, 25 (group 1) in primary intent and 15 (group 2) for a local recurrence after CRT. Two days after intravenous (IV) Photofrin (2 mg/kg), the phototherapy was performed with a dye laser. The treatment response and severe complications, defined as perforation and stricture requiring endoscopic dilation, were compared between the two groups. RESULTS The patient and tumor characteristics were not different between the two groups. In group 1, 19 out of 25 patients (76%) were successfully treated versus 8 out of 15 patients (53%) in group 2 (P= 0.17). Severe complications occurred more frequently in patients with a prior CRT (8%vs 46.7%, P= 0.008) and included two perforations and five strictures requiring endoscopic dilation, while only two strictures occurred in group 1. A prior CRT was an independent risk factor of severe complications (odds ratio [OR] 8.05; 95% confidence interval [CI]1.22-43.0). CONCLUSIONS Severe complications were significantly more frequent in patients treated after a prior CRT. PDT as a salvage therapy in patients with a local recurrence after CRT for esophageal cancer tended to be less efficient than in first-line treatment.

Abstract
BACKGROUND To date, there are no large endoscopic studies in systemic sclerosis (SSc), and both prevalence and characteristics of watermelon stomach in SSc have not been determined. AIMS To determine the prevalence, clinical presentation, endoscopic appearance, therapy success and long-term outcome in SSc patients with watermelon stomach and make predictions about which SSc patients are at risk for watermelon stomach. Patients and methods From 1990 to 2008, 264 patients were seen for evaluation of SSc. Data were collected as regards patients' characteristics, time of watermelon stomach onset, features, therapy and outcome of watermelon stomach. RESULTS Fifteen SSc patients (5.7%) exhibited watermelon stomach. SSc onset preceded watermelon stomach manifestations in 13 patients (86.7%). Most patients (86.7%) presented with iron-deficiency anaemia, two other patients experienced gastrointestinal haemorrhage. Gastroscopy disclosed typical 'watermelon stomach' characterized by prominent, erythematous stripes, radiating in a spoke-like fashion from the antrum to the pylorus. All patients received conservative therapy; because of deterioration of watermelon stomach, eight patients (53.3%) underwent endoscopic procedures. During follow-up, five patients (33.3%) exhibited recurrences of watermelon stomach. CONCLUSIONS Our series indicates that watermelon stomach should be considered when unexplained iron-deficiency anaemia occurs in SSc patients. Moreover, because watermelon stomach may be the first manifestation of SSc, patients with unexplained watermelon stomach should systematically undergo physical examination and autoantibody testing to detect the underlying SSc.

Abstract
BACKGROUND Capsule endoscopy (CE) is the first procedure to explore the small bowel in obscure GI bleeding (OGB). OBJECTIVE To evaluate the role of bowel preparation with oral sodium phosphate (NaP) in this indication. DESIGN A prospective multicenter, controlled, randomized, blind study. METHODS A total of 129 patients with the diagnosis of OGB were included and were randomized into 2 groups (group A [n = 64] and group B [n = 63]). In group A, a CE was performed after an 8-hour fasting period. In group B, patients were asked to drink 2 doses of 45 mL NaP before swallowing the capsule. The quality of the images was assessed at 5 different locations of the small bowel. Bowel cleanliness and visibility were evaluated by using 2 scoring systems, which included assessing the presence of bubbles, liquid, and the rate of visibility. RESULTS A total of 127 patients (53 men; mean age 56.9 years, range 19-90 years) were analyzed for the preparation and detection of lesions (2 patients were not able to swallow the capsule). No difference was observed for cleanliness and visibility between the 2 groups at any of the small-bowel segments; no difference was found for gastric transit time (39.8 minutes vs 35.7 minutes, P = .63), small-bowel transit time (257.5 minutes vs 248.6 minutes, P = .59), and the detection of lesions (35.9% vs 42.8%, P = .54). LIMITATIONS The evaluation of bowel cleanliness was based on subjective features. CONCLUSIONS The results of the present study, despite a significant number of limitations, did not support that small-bowel preparation with oral NaP can be recommended for CE exploration in patients with OGB.

Abstract
BACKGROUND AND AIM Esophageal capsule endoscopy (ECE) is a new technology that allows noninvasive investigation of the esophagus. Our aim was to evaluate prospectively the diagnostic yield of ECE in patients with chronic reflux symptoms. PATIENTS AND METHODS Eighty-nine patients (40 men, mean age 54 yr) referred to five endoscopic centers for esophagogastroduodenoscopy (EGD) were enrolled. Patients first underwent ECE, then EGD; endoscopists who performed the EGD were blind to the ECE data that were interpreted separately by two independent readers. The Los Angeles, Prague, and Montreal classification systems were used to describe endoscopic findings. RESULTS Seventy-seven patients completed the study. Esophagitis and endoscopically suspected esophageal metaplasia (ESEM) were present in 24 and 10 patients, respectively. Columnar lining was histologically confirmed in seven patients (3 with specialized intestinal metaplasia and 4 with gastric metaplasia). The kappa values for interobserver agreement regarding the diagnosis of esophagitis and ESEM were 0.67 (0.49-0.85) and 0.49 (0.17-0.81), respectively. The diagnostic yields of ECE to detect esophagitis and ESEM were as follows: sensitivity 79% and 60%, specificity 94% and 100%, positive predictive value (PPV) 83% and 100%, negative predictive value (NPV) 92% and 95%, respectively. CONCLUSION As a screening tool in patients with reflux symptoms, ECE has an excellent specificity and NPV for the diagnosis of esophagitis and ESEM. However, its sensitivity for the diagnosis of ESEM is not optimal. Further studies are necessary to improve the procedure, and to compare the cost-effectiveness of strategies using ECE or EGD.

Abstract
BACKGROUND Gastric vascular ectasia (GVE) is an uncommon etiology of GI bleeding. GVE can affect not only patients with cirrhosis but also patients with a variety of chronic diseases. OBJECTIVE The aim of the study was to compare clinical and endoscopic patient characteristics and responses to treatment by argon plasma coagulation (APC) of bleeding GVE between patients with cirrhosis and noncirrhotic patients. DESIGN Retrospective study of consecutive patients. PATIENTS Between January 2001 and December 2005, 30 patients were treated by APC for bleeding GVE. INTERVENTIONS Clinical and endoscopic features and APC treatment success were compared between patients with cirrhosis (group 1) and noncirrhotic patients (group 2). MAIN OUTCOME MEASUREMENTS Endoscopic treatment efficacy was assessed on the recurrence of symptoms after APC. RESULTS Seventeen patients were cirrhotic and 13 had no cirrhosis. Cirrhotic patients presented more frequently with overt bleeding (65% vs 15%) and noncirrhotic patients with occult bleeding with iron deficiency anemia (35% vs 85%, P= .01). Endoscopy in noncirrhotic patients revealed more frequently a "watermelon" appearance (23.5% vs 76.9%, P= .008). Endoscopic treatment by APC was successful in 83.3% of patients (88.2% vs 76.9%, not significant). Patients from group 2 required significantly more APC sessions to achieve a complete treatment (2.18 vs 3.77, P= .04). CONCLUSIONS APC treatment of bleeding GVE was efficient and safe in cirrhotic and noncirrhotic patients in more than 80% of cases. Noncirrhotic patients required significantly more APC sessions to achieve a complete treatment. An endoscopic watermelon appearance and the use of antiplatelet drugs were associated with failure of APC.

Abstract
BACKGROUND Double stenting of oesophagus and airways may be required in palliative treatment of patients with locally advanced oesophageal cancer. AIM To assess feasibility, efficacy and complications occurring in patients with locally advanced oesophageal cancer receiving both oesophagus and airways stenting. METHODS In one single centre between 1997 and 2005, among 180 patients with locally advanced oesophageal cancer treated by the palliative placement of a self-expanding metal stent, patients requiring double stenting of oesophagus and airways were identified. Clinical efficacy, complications and survival were retrospectively collected. RESULTS Fifteen patients (8.3% of 180) required a double stenting at follow-up. Symptomatic efficacy of oesophagus and airways stenting was 86.7% for dysphagia and 100% for dyspnoea. Median survival after the second stent insertion was 99 days. Life-threatening early complications occurred in three patients after double stenting (20%), including two deaths following oesophageal perforation and massive haemoptysis, respectively. Procedure-related mortality was 13.3%. CONCLUSIONS Double stenting of oesophagus and airways is feasible in patients with locally advanced oesophageal cancer, with a relevant clinical efficacy. However, early major complications including procedure-related death may occur in as many as 20% of patients. This treatment should be reserved to very selected patients with severe symptoms and end-stage disease.

Abstract
BACKGROUND Self-expanding metallic stents (SEMS) are a first-line therapeutic procedure in the palliative treatment of dysphagia in patients with esophageal cancer. However, the impact of SEMS insertion on patient nutritional status has never been assessed. OBJECTIVE To evaluate the nutritional status of patients after insertion of a SEMS and the impact of a preexisting undernutrition status on survival. DESIGN Retrospective observational study. PATIENTS A total of 120 patients treated in a single center by insertion of a SEMS for relief of dysphagia in the palliative treatment of esophageal cancer were retrospectively included. MAIN OUTCOME MEASUREMENTS Efficacy of SEMS was assessed by the Ogilvie's dysphagia score. Patient nutritional and clinical statuses were evaluated at SEMS insertion, and patients were regularly followed until death. Independent predictive factors of early 30-day mortality were researched. RESULTS Dysphagia scores decreased after SEMS insertion in 89.1% of patients, with median scores decreasing from 3.0 to 1.0 (P < .05). There was a significant decrease in body mass index (BMI) (P < .04), serum albumin level (P < .01), and World Health Organization (WHO) performance index (P < .02) at a 1-month evaluation. Serum albumin level, BMI <18 kg/m(2), and WHO performance index >2 at SEMS insertion were independent predictive factors of 30-day mortality. CONCLUSIONS This study suggested that palliative stent placement in esophageal cancer was effective to relieve dysphagia but was not followed by an improvement of nutritional parameters. Moreover, it underlined the key role played by undernutrition on survival.

Abstract
BACKGROUND AND STUDY AIMS Celiac disease can manifest with nonspecific symptoms, including functional gastrointestinal disorders such as dyspepsia. The aim of our study was to assess the usefulness of duodenal endoscopic markers of villous atrophy for the selection of dyspeptic patients for histological assessment. PATIENTS AND METHODS Esophagogastroduodenoscopy was performed in dyspeptic patients, in patients considered to be at risk of having celiac disease, and in healthy controls. At least three duodenal biopsies were performed for histological assessment of villous atrophy in all patients and controls. We looked for the following four duodenal endoscopic markers of celiac disease: reduction in the number of folds, scalloping of folds, mosaic-pattern mucosa, and nodular mucosa. RESULTS A total of 175 people were enrolled (75 patients with dyspepsia; 75 patients who were "at risk" of having celiac disease; and 25 healthy volunteers, or "controls"). Of the dyspeptic patients, four had endoscopic markers of celiac disease with no histologically confirmed villous atrophy, while one patient without endoscopic markers was found to have Marsh type I villous atrophy. Of the patients at risk of having celiac disease, 16 had at least one endoscopic marker and 10/16 were found to have histological villous atrophy. In this group, the sensitivity and specificity of the endoscopic markers were 100 % and 90.8 % respectively. "At-risk" patients with two or more endoscopic markers all had histologically confirmed villous atrophy. Neither endoscopic markers nor villous atrophy were found in any of the control patients. CONCLUSIONS Additional endoscopic markers are valuable for diagnosis in patients with clinical symptoms suggestive of celiac disease. In contrast, endoscopic markers of villous atrophy are not useful for selecting a subgroup of dyspeptic patients for screening for celiac disease by duodenal histological assessment. These patients should be screened using other protocols.

Abstract
BACKGROUND Self-expanding metal stents are used routinely to palliate dysphagia due to oesophageal cancer. STUDY AIM To compare the frequency of life-threatening complications after self-expanding metal stent insertion, depending on whether patients received prior chemoradiotherapy or no treatment. PATIENTS AND METHODS During 7 years, 116 consecutive patients were treated at a single centre in a palliative intent by insertion of self-expanding metal stent for dysphagia due to an oesophageal cancer. Patients were retrospectively separated into two groups: patients with chemoradiotherapy before self-expanding metal stent insertion (group 1, n = 56) and patients with no treatment before or after self-expanding metal stent insertion (group 2, n = 60). Life-threatening complications were compared and predictive risk factors of postprocedure complications were identified. RESULTS Median dysphagia was significantly improved during the first month (grade 3 to grade 1 in the two groups). Early and late major complications occurred more frequently in group 1 (23.2% vs. 3.3%; P < 0.002 and 21.6% vs. 5.1%; P < 0.02 respectively). Prior chemoradiotherapy was the only independent predictive factor of postprocedure major complications, with an odds ratio of 5.59 (CI 95% 1.7-18.1). CONCLUSIONS Life-threatening complications after palliative self-expanding metal stent placement seem to occur more frequently in patients with prior chemoradiotherapy. Prevention of these severe complications should be considered before stenting.

Abstract
AIMS Fluoroscopy is not available in every endoscopic unit. This situation leads to delays in treatment or to transfer of patients to other centres for stent insertion. We assessed safety and effectiveness of expandable esophageal metal stent placement under endoscopic control without fluoroscopy using a thin gastroscope. PATIENTS AND METHODS From October 2002 to June 2004, thirty-three consecutive patients have been included for esophageal stent placement under endoscopic control alone with a nasogastroscope (5.9 mm). A proximal release covered stent (Ultraflex; Boston Scientific Microvasive) was used. Indications were malignant esophageal stricture (N = 26), malignant extrinsic compression (N = 2 ) and esophago-respiratory neoplastic fistulae (N = 5). RESULTS Stent placement using endoscopic control alone was successful in 30/33 (90%) patients. Complications occurred in 11 patients. Early complications (<7 days) included one death from pulmonary embolism, severe retrosternal pain needing transient morphinic treatment (N = 2) and GERD despite antisecretory therapy (N = 1). Late complications included: food impaction (N = 1), tumour overgrowth-related obstruction of the stent (N = 5) and one late esophago-respiratory fistula at 4 months at the proximal end of the stent. Relief of dysphagia was obtained for all patients at 48 hours and dysphagia score decreased from 3.1 before stent to 1.2 at 1 month (P < 0.05). CONCLUSION Expandable esophageal stents can be accurately and safely placed using endoscopy with a thin gastrosocope. This method obviates the requirement of fluoroscopic access, lacking in many centres, and avoids exposure to X-ray.

Abstract
BACKGROUND Gastric retention and delayed gastric emptying of the video capsule are major limitations. We retrospectively studied gastric transit time, gastric retention, and completeness of capsule endoscopy (CE) in relation to the conditions in which it was performed. METHODS From May 2002 to September 2004, CE was performed in 190 patients (92 men; mean age, 58.4 years, range 16-91 years). Patients were stratified according to the way CE was performed (hospital day setting, outpatient, or ongoing hospitalization), and the recordings were analyzed to measure gastric retention, gastric transit time, and the completeness of the examinations. RESULTS CE examination was performed in a hospital day setting in 100 patients, in an outpatient setting in 61, and during hospitalization in 29. Gastric retention of the capsule occurred in 8 of 190 patients (4.2%) (5 women, 3 men; mean age, 37.9 years). Gastric retention occurred during hospitalization in 7/29 (24.1%) and in hospital day setting in one of 100. Ongoing hospitalization was statistically associated with an increased risk of gastric capsule retention (p < 0.0001). The cecum was reached in 165/190 (87%), and ongoing hospitalization was associated with a lower rate of complete examinations (p < 0.001). Small-bowel transit time was similar, regardless of the circumstances of CE performance. CONCLUSIONS Ongoing hospitalization is a major cause of gastric retention and incomplete examination by CE. Therefore, CE performance during ongoing hospitalization may require the use of a prokinetic agent.

Abstract
AIMS Small bowel contents can sometimes hamper the quality of capsule images. Our aim was to investigate the effect of PEG administered prior to capsule endoscopy (CE) upon quality of images, gastrointestinal transit time, and detection rate of small bowel bleeding lesions in patients with obscure gastrointestinal bleeding. PATIENTS AND METHODS Forty-two consecutive patients were included. CE was performed following a 12-hour fasting period. The 16 first patients (Group A) received no preparation and the following 27 patients (Group B) received 2 L of PEG the night before. The quality of images was assessed at both in duodenojejunum and ileum level, using a scale including the presence of air bubbles, biliary secretion, and residue (1-4). RESULTS Quality of images were not different in Group A compared with Group B in the duodenojejunum and in the ileum. Gastric transit time tended to be shorter in Group A compared with Group B (25.5 vs. 45.7 minutes) (P = 0.15), whereas small bowel transit was not different between both groups (271 vs. 288 minutes). Total small bowel CE examination was complete in Group A and in 24 of 26 in Group B (not significant). Potential bleeding lesions were seen in 8 patients in Group A and 12 in Group B (not significant). CONCLUSION Our retrospective study suggests that 2 L PEG preparation seems able to improve neither the quality of CE images nor its diagnostic performance. Moreover, in our study, PEG tended to increase gastric emptying time and may constitute a limitation for small bowel complete examination.

Abstract
AIM The main aim of this study was to evaluate efficacy and therapeutic impact of capsule endoscopy (CE) in obscure gastrointestinal bleeding (OGIB). In addition, we evaluated the software of automatic detection of red zones (SBI, Given Imaging). PATIENTS AND METHODS From June 2002 to June 2003, thirty-five patients with OGIB underwent capsule endoscopy after negative upper and lower digestive endoscopy. Capsule endoscopy was performed following a 12-hour fasting period and some received 2 L of PEG the night before for bowel preparation. RESULTS CE was performed for occult (N=18) or overt (N=17) OGIB. Potentially bleeding lesions were found in 16/35 patients (45.7%). Lesions were angiodysplasias (N=8), ulcerations (N=4), tumors (N=2) and active bleeding without visible lesion (N=2). Lesions were located in gastric antrum (N=1), duodenum (N=2) and jejuno-ileum (N=13). Endoscopic (N=10), surgical (N=2) or medical (N=1) treatments were performed in 13/35 (37%). SBI was retrospectively evaluated in 24 patients with sensitivity, specificity, positive and negative predictive value of respectively 45%, 73%, 50% and 69%. CE retention during 10 days occurred in a patient with a small bowel NSAID-induced stricture. CONCLUSION CE is a safe and effective procedure in the management of OGIB and had a therapeutic impact in more than one third of patients.

Abstract
AIMS We evaluate prospectively effectiveness, tolerance, predictive factors of failure and complications of argon plasma coagulation (APC) in the treatment of hemorrhagic radiation proctitis (HRP). PATIENTS AND METHODS Twenty-seven patients were treated by APC for HRP. Eight patients needed blood transfusion before APC. Six patients were anti-coagulated and one had severe thrombocytopenia. APC was performed without sedation in 25/27 patients. Before APC treatment, bowel preparation was performed by enema (n = 19 sessions), polyethylene glycol or sodium phosphate (n = 53 sessions). APC treatment was performed every 5 weeks. Effectiveness of APC was based on clinical and endoscopic score and biological status before and after APC treatment. RESULTS The mean follow-up was 13.6 months (range, 3-31 months). After one to seven sessions of APC (average, 2.66 sessions), twenty-five patients (92%) had no recurrence of bleeding. The bleeding score decreased from 3.03 to 0.42 (P < 0.001) and the endoscopic score from 3.08 to 0.73 (P < 0.001). Out of the eight patients requiring blood transfusion prior to APC sessions, only one required blood transfusion after APC (P < 0.05). One late relapse was observed and successfully re-treated by APC. Side effects were anal or rectal pain (n = 3) and vagal symptoms (n = 2). Three colonic explosions occurred, with perforation leading to surgery in one case. The incidence of bowel explosion was higher after local preparation (3/19 sessions) compared with oral preparation (0/53 sessions) (P < 0.05). No stricture due to APC appeared, even if telangiectasias coagulated during a session were circumferential. CONCLUSION Coagulation by APC is an effective and safe treatment of HRP if a complete cleansing preparation is performed to avoid explosion.
