Aim: to evaluate the utility of double-balloon enteroscopy for small-bowel disease. Design: a prospective study of 50 consecutive enteroscopies performed from December 2004 to July 2005 to analyze diagnoses and treatments. Patients: 44 patients (33 had undergone a previous capsule endoscopy) with indications for obscure digestive hemorrhage, angiodysplasia, Peutz-Jeghers syndrome, ulcer, suspected Crohn's disease, tumors, and refractory celiac disease. Results: we carried out enteroscopy studies in 44 patients by the oral route and, in 6 additional patients, by both the oral and anal routes. We reached the ileon with the oral route in all cases but one (jejunal stenosis), and in 4 cases out of 7 with the anal route, with an average duration of 73 minutes. We found angiodysplasia in 19 cases, as well as NSAID-related enteropathy, Crohn's disease, diverticulosis, and Waldenström's disease. We performed biopsies in 31% of cases with diagnoses of adenocarcinoma, lymphangiectasia secondary to tumor in celiac disease, and Whipple's disease. We treated 19 patients with angiodysplasia (1 to 20 synchronous lesions) with argon, and 4 patients with polyps using polipectomy (sporadic polyps or Peutz-Jeghers syndrome). A retained capsule in one patient with stenosis was removed. Conclusions: double-balloon enteroscopy is a useful and effective technique in the diagnosis and treatment of small intestine diseases, thus complementing capsule endoscopy. More studies are needed to analyze its impact on the management of this condition.Objetivo: valorar la utilidad de la enteroscopia de doble balón en enfermedades de intestino delgado. Diseño: estudio prospectivo descriptivo de 50 enteroscopias consecutivas (diciembre 2004 a julio 2005), analizando diagnóstico y terapéutica. Pacientes: cuarenta y cuatro pacientes (33 con cápsula endoscópica previa) con hemorragia digestiva oculta o lesiones detectadas mediante cápsula (angiodisplasias, pólipos, úlceras, enfermedad de Crohn, celiaca refractaria y tumores). Resultados: se realizó enteroscopia vía oral a 44 pacientes y vía oral más anal a 6. Por vía oral se progresó hasta íleon en todos los casos excepto uno (estenosis yeyunal), por vía anal en 4 de 7 (3 casos con dificultad de paso por Bahuin). La duración media fue 73 minutos. Se detectaron angiodisplasias (19 casos), úlceras en enteropatía por AINE, enfermedad de Crohn, enfermedad de Waldenström, y divertículos. Se realizaron biopsias en yeyuno-íleon en un tercio de los casos (adenocarcinoma, linfangiectasias secundarias a tumor sobre celíaca, enfermedad de Whipple). Se realizó terapéutica con argón a 19 pacientes con angiodisplasias (1 a 20 lesiones), polipectomía a 4 pacientes con pólipos esporádicos o Peutz Jeghers (1 a 15 pólipos) y se extrajo una cápsula endoscópica retenida en una estenosis. Conclusiones: la enteroscopia de doble balón es una técnica útil y eficaz en el diagnóstico y tratamiento de las lesiones del intestino delgado, complementando a la cápsula endoscópica. Hacen falta más estudios para analizar el impacto esperado en el cambio del manejo de estos pacientes.

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.

Hypercoagulability is a extraintestinal manifestation of inflammatory bowel disease, which could provoke thromboembolic phenomena. Central nervous system venous thrombosis is a rare complication and could be unnoticed. We report on a patient with ulcerative colitis who presented cerebral venous sinus thrombosis as the first manifestation of a hypercoagulable state. We review the literature and discuss about the pathogenic mechanisms of such complication.

During blunt abdominal trauma the small bowel and/or its mesentery may be injured; if abdominal trauma occurs after compression by an incorrectly-applied seat belt, underlying viscera may be crushed between the vertebral and the seat belt; ischemia or infarction of the intestinal wall, and delayed fibrosis and stenosis may occur. We present a patient, operated on two months after blunt abdominal trauma, with small bowel obstruction secondary to post-traumatic intestinal fibrosis. Assuming that this condition is rarely suspected, a delayed diagnosis and treatment of these patients may occur.
