AIM To evaluate the rate of adverse events(AEs) during consecutive gastric and duodenal polypectomies in several Spanish centers. METHODS polypectomies of protruded gastric or duodenal polyps ≥ 5 mm using hot snare were prospectively included. prophylactic measures of hemorrhage were allowed in predefined cases. AEs were defined and graded according to the lexicon recommended by the American Society for Gastrointestinal Endoscopy. patients were followed for 48 h, one week and 1 mo after theprocedure. RESULTS308 patients were included and a single polypectomy was performed in 205. Only 36(11.7%) were on prior anticoagulant therapy. Mean polyp size was 15 ± 8.9 mm(5-60) and in 294 cases(95.4%) were located in the stomach. Hemorrhage prophylaxis was performed in 219(71.1%) patients. Nine patients presented AEs(2.9%), and 6 of them were bleeding(n = 6, 1.9%)(in 5 out of 6 AE, different types of endoscopic treatment were performed). Other 24 hemorrhagic episodes could be managed without any change in the outcome of the endoscopy and, consequently, were considered incidents. We did not find any independent risk factor of *** Gastroduodenal polypectomy using prophylactic measures has a rate of AEs small enough to consider this procedure a safe and effective method for polyp resection independently of the polyp size and location.

AIMTo analyze the diagnostic yield (DY), therapeutic impact (TI) and safety of capsule endoscopy (CE).METHODSThis is a multi-centre, observational, analytical, retrospective study. A total of 163 patients with suspicion of celiac disease (CD) (mean age = 46.4 ± 17.3 years, 68.1% women) who underwent CE from 2003 to 2015 were included. patients were divided into four groups: seronegative CD with atrophy (Group-I, n = 19), seropositive CD without atrophy (Group-II, n = 39), contraindication to gastroscopy (Group-III, n = 6), seronegative CD without atrophy, but with a compatible context (Group-IV, n = 99). DY, TI and the safety of CE were *** overall DY was 54% and the final diagnosis was villous atrophy (n = 65, 39.9%), complicated CD (n = 12, 7.4%) and other enteropathies (n = 11, 6.8%; 8 Crohn’s). DY for groups I to IV was 73.7%, 69.2%, 50% and 44.4%, respectively. Atrophy was located in duodenum in 24 cases (36.9%), diffuse in 19 (29.2%), jejunal in 11 (16.9%), and patchy in 10 cases (15.4%). Factors associated with a greater DY were positive serology (68.3% vs 49.2%, p = 0.034) and older age (p = 0.008). On the other hand, neither sex nor clinical presentation, family background, positive histology or HLA status were associated with DY. CE results changed the therapeutic approach in 71.8% of the cases. Atrophy was associated with a greater TI (92.3% vs 45.3%, p patients responded to diet. There was one case of capsule retention (0.6%). Agreement between CE findings and subsequent histology was 100% for diagnosing normal/other conditions, 70% for suspected CD and 50% for complicated *** has a high DY in cases of suspicion of CD and it leads to changes in the clinical course of the disease. CE is safe procedure with a high degree of concordance with histology and it helps in the differential diagnosis of CD.

AIM: To assess the double-balloon enteroscopy(DBE) role in malignant small bowel tumors(MSBT).METHODS: This is a retrospective descriptive study performed in a single center. All consecutive patients who underwent a DBE with final diagnosis of a malignant neoplasm from 2004 to 2014 in our referral center were included. patient demographic and clinical pathological characteristics were recorded and reviewed. MSBT diagnosis was achieved either by DBE directed biopsy with multiple tissue sampling, endoscopic findings or histological analysis of surgical specimen. We have analyzed double-balloon enteroscopy impact in outcome and clinical course of these patients. RESULTS: Of 627 patients, 28(4.5%)(mean age = 60 ± 17.3 years) underwent 30 procedures(25 anterograde, 5 retrograde) and were diagnosed of a malignant tumor. patients presented with obscure gastrointestinal bleeding(n = 19, 67.9%), occlusion syndrome(n = 7, 25%) and diarrhea(n = 1, 3.6%). They were diagnosed by DBE biopsy(n = 18, 64.3%), histological analysis of surgical specimen(n = 7, 25%) and unequivocal endoscopic findings(n = 2, 7.1%). Gastrointestinal stromal tumor(n = 8, 28.6%), adenocarcinoma(n = 7, 25%), lymphoma(n = 4, 14.3%), neuroendocrine tumor(n = 4, 14.3%), metastatic(n = 3, 10.7%) and Kaposi sarcoma(n = 1, 3.6%) were identified. DBE modified outcome in 7 cases(25%), delaying or avoiding emergency surgery(n = 3), modifying surgery approach(n = 2) and indicating emergency SB partial resection instead of elective approach(n = 2).CONCLUSION: DBE may be critical in the management of MSBT providing additional information that may be decisive in the clinical course of these patients.

AIM: To determine the hypothesis that inflating the balloons in the duodenal papilla determines changes in the biochemical markers of ***: Four groups of pigs were used: Group papilla(Gp), the overtube's balloon was inflated in the area of the papilla; Gp + double balloon enteroscopy(Gp + DBE), the overtube's balloon was kept inflated in the area of the papilla for 20 min before a DBE; Group DBE(GDBE), DBE was carried out after insuring the balloon's inflation far from the pancreatic papilla; and Group control(GC). Serum concentrations of amylase, lipase and C-reactive protein(CRp) were evaluated. pancreases were processed for histopathology ***: Main changes occurred 24 h after the procedure compared with baseline levels. Amylase levels increased significantly in Gp(59.2% higher) and were moderately higher in groups Gp + DBE and GDBE(22.7% and 20%, respectively). Lipase increased in Gp and Gp + DBE, whereas it hardly changed in GDBE and in GC. CRp increased significantly in Gp, Gp + DBE and GDBE, while no changes were reported for GC. No statistically significant difference between groups Gp and Gp + DBE was found for the histopathological findings, except for vacuolization and necrosis of the pancreatic parenchyma that was higher in Gp than in Gp + ***: The manipulation of the duodenal papilla by the inflated overtube's balloon during DBE causes pancreatic structural damage and increased biochemical markers associated with pancreatitis.

AIM： To evaluate the effect of double-balloon enteros- copy （DBE） on pancreas histology and levels of pancre- atic enzymes. METHODS： Conventional upper gastrointestinal endos- copy was performed on five control pigs. Oral DBE was performed with an EN-450T5 enteroscope on 20 pigs. Two experimental groups （10 pigs each） were defined according to DBE duration： 90 rain for Group 1 and 140 min for Group 2. During oral insertion, the balloons were not inflated in the descending part of the duodenum to avoid the minor duodenal papilla. Serum amy- lase, lipase and C-reactive protein （CRp） levels were monitored before the procedure and repeated every 30 min until the exploration was finished, as well as 24 h and 7 d after. After the procedure and for a total of 7 d, the pigs were observed twice a day for signs of de- creased activity, irritability, vomiting or anorexia. Gross and microscopic examination of the pancreas was per- formed on day 7. RESULTS： All animals tolerated DBE without clini- cal manifestations of acute pancreatitis. Experimental groups had higher levels of enzymes than the control group at 24 h. Throughout the exploration, the amylase levels increased significantly above the baseline 24 h after DBE, although the increase was not statistically significant and did not reach 20% of the baseline. An increase in lipase and CRp was observed at 24 h after the procedure, although by day 7, all enzymatic lev- els had returned to baseline. No differences between Groups 1 and 2 were found for any enzyme and sam- pling site during and after the procedure. Similarly, no correlation between insertion depth and enzyme levels was observed. Direct in situ and post-removal inspec- tion of the pancreas did not show any evidence of fluid collection, abscesses or hemorrhage. Histological examination of the pancreas from Groups 1 and 2 re- vealed the existence of focal areas （0.14-0.26 mm2） of ischemic necrosis in 47.4% of the animals. In the pigs with damaged pancreas, the lef
