Introduction: Dieulafoy's lesion of the small bowel is an uncommon cause of gastrointestinal (GI) bleeding that often recurs after endoscopic treatment., Material and Methods: we report an observational, descriptive, retrospective, single-center study in 15 patients with small bowel bleeding who were diagnosed with a Dieulafoy's lesion by capsule endoscopy or double-balloon enteroscopy., Results and Conclusions: all patients underwent combined endoscopic treatment. During a median follow-up of 33.5 months (range, 2-145), three of the 12 cases that stayed in follow-up (25 %) recurred, all within 48 hours after treatment. Two were successfully re-treated with a repeat endoscopic procedure.

Background and Aim: Intermediate-risk patients following a colorectal cancer screening program may have differential risk of advanced lesions depending on the findings of an index colonoscopy. The aim of the present study was to comparatively assess advanced colorectal neoplasia risk at the first follow-up colonoscopy among the different intermediate-risk subgroups with a focus on patients with three to four adenomas., Methods: All patients recruited for a baseline screening colonoscopy between 2006 and 2011 were included. Number, size and histopathological characteristics of adenomas were collected. Main outcome was an advanced colorectal neoplasia detection rate (invasive carcinoma or advanced adenoma) at the first follow-up colonoscopy. Low- and high-risk patients were excluded., Results: Five hundred and sixty-one intermediate-risk patients (63.3% men, mean age: 59.01 ± 6.16 years) underwent indexing and follow-up colonoscopy. By multivariate analysis, three to four adenomas (OR: 3.613 [95% CI: 1.661-7.859], P = 0.001) and adenoma size ≥10 <20 mm (OR: 3.374 [95% CI: 1.618-7.034], P = 0.001) were independent factors associated with advanced colorectal neoplasia. Advanced lesions were detected in 7.66% of cases. Of patients with advanced colorectal neoplasia, 51.16% belonged to the three-to-four-adenoma group and ≥1 of ≥10 <20-mm subgroups (n = 132, 23.53%). These patients demonstrated a higher rate of advanced lesions [OR: 3.886 (95% CI: 2.061-7.325), P < 0.001] than patients with three to four small adenomas of <10 mm (16.67% vs 5.07%, P < 0.001). The association between patients with small adenomas (n = 217, 38.68%) and advanced lesions was not significant (OR: 0.521 [95% CI: 0257-1.056], P = 0.066)., Conclusion: Intermediate-risk patients with three to four small adenomas achieved a very low advanced lesion rate at follow up. Surveillance interval should be lengthened because these patients should be considered low risk., (© 2015 Japan Gastroenterological Endoscopy Society.)

Background and Aim: Capsule endoscopy and double balloon enteroscopy are well-recognized procedures in obscure gastrointestinal bleeding, with many factors that may influence their diagnosis yield. The aim of the present study was to characterize the degree of agreement between both techniques with focus on the type of lesion in a large cohort of patients at a referral center., Material and Method: One thousand two hundred and nine capsules were administered in 1,078 patients and 381 enteroscopies were performed in 361 patients with obscure-gastrointestinal bleeding from 2004 to 2014., Results: Both procedures were carried out in 332 patients (mean age: 65.22 +/- 15.41, 183 men) and they have a similar diagnosis yield (70.5% vs. 69.6%, p = 0.9). Overall enteroscopy diagnosis yield was higher within patients with a previous positive capsule endoscopy (79.3% vs. 27.9%, p < 0.001). The degree of agreement was very good for polyps (0.89 [95% CI: 0.78-0.99]), good for vascular lesions (0.66 [95% CI: 0.55-0.77]) and tumors(0.66 [95% CI: 0.55-0.76]) and moderate for ulcers (0.56 [95% CI: 0.46-0.67]). Diverticula (0.39 [95% CI: 0.29-0.5]) achieved a fair agreement. The results of CE and DBE differed in 73 patients (22%)., Conclusions: The present study confirms that although overall diagnostic yield by capsule endoscopy and double-balloon enteroscopy is similar, there are many factors which can modify these values, mainly the type of lesion.

Background and Aim: There are few data concerning emergency double-balloon enteroscopy (DBE) and its usefulness in the management of severe acute obscure gastrointestinal bleeding (OGIB). The aim of this retrospective study was to evaluate emergency DBE and capsule endoscopy (CE) in patients with overt OGIB, analyzing the feasibility of this combined approach., Methods: Emergency DBE in patients with overt OGIB was defined as performance within 24 h of symptom onset. We reported 27 patients (16 men, mean age: 64.6 ± 17.9 years) with overt severe bleeding who underwent 29 emergency DBE (22 anterograde, 7 retrograde). Of 27 patients, 16 (59.3%) underwent CE with real time (RT) viewing., Results: Patients were diagnosed with the following: Dieulafoy's lesion (DL; n = 11, 40.7%), angioectasia (n = 7, 25.9%), tumors (n = 4, 14.8%), diverticulum (n = 3, 11.1%), ulcers (n = 2, 7.4%). We diagnosed 23 lesions amenable to endoscopic hemostasis and successfully treated 21 of them (77.8%). DL detection rate was statistically higher in the emergency DBE group than in OGIB patients with DBE done 24 h after symptom onset (40.7% vs 0.9%, respectively, P < 0.001). Combined approach with RT viewing by CE correctly modified DBE management in four patients (25%)., Conclusions: Emergency DBE is feasible, safe and effective in acute OGIB and may avoid major surgery, diagnosing and successfully treating most patients. Combined approach with RT viewing by CE is especially useful to identify recurrent bleeding vascular lesions such as DL that may be easily misdiagnosed by non-emergency DBE., (© 2014 The Authors.

Objective: To analyze the clinical characteristics, treatment, and follow-up of a cohort of 29 patients with Wilson's disease (WD) within the region of Murcia., Patients and Method: We reviewed the medical records of 29 cases of WD (mean age, 20.3 +/- 13.4 years) diagnosed during the last 16 years., Results: The most frequent reason for consultation was upon discovering a high transaminase level in almost half the patients, followed by tremors or dystonia in 17% of patients, respectively. A Kayser-Fleischer ring was observed in 17/29 (58.6%) of patients (100% of patients with pure neurological involvement and 35% of patients with pure clinical hepatic disease; p < 0.001). Blood copper levels not associated with ceruloplasmin as well as cupruria were notably superior in patients with neurological symptoms and in those with liver cirrhosis at the time of diagnosis. Patient clinical symptoms remained stable with D-penicillamine or trientine, or improved during the observation period, for 18 out of 29 patients (62%), while 11 out of 29 patients (38%) got worse., Conclusions: In our region patients with WD are diagnosed at a younger age, and in most cases for hepatic disease. Patients with neurological disease or liver cirrhosis had a high level of free copper not associated to ceruloplasmin and cupruria. The disease had a favorable evolution in all patients but those diagnosed with hepatic disease or advanced neurological disease.
