Abstract
Noninvasive imaging with CT and magnetic resonance enterography or direct visualization with wireless capsule endoscopy can provide valuable diagnostic information and direct therapy. Enteroscopy technology and techniques have evolved significantly and allow diagnosis and therapy deep within the small bowel, previously attainable only with intraoperative enteroscopy. Push enteroscopy, readily available in most endoscopy units, plays an important role in the evaluation and management of lesions located up to the proximal jejunum. Currently available device-assisted enteroscopy systems, DBE, SBE, and spiral enteroscopy each have their technical nuances, clinical advantages, and limitations. Newer, on-demand enteroscopy systems appear promising, but further studies are needed. Despite slight differences in parameters such as procedural times, depths of insertion, and rates of complete enteroscopy, the overall clinical outcomes with all overtube-assisted systems appear to be similar. Endoscopists should therefore master the enteroscopy technology based on institutional availability and their level of technical expertise.

Abstract
BACKGROUND The aim of the present study was to evaluate the efficacy and safety of double balloon enteroscopy (DBE) in children with inflammatory bowel disease (IBD). METHODS A total of 106 DBE procedures in 67 patients were performed at Mie University Hospital from January 2008 to June 2011. Of these, 17 procedures in 12 children and adolescents with established or suspected Crohn's disease (CD) were included in the present study. The procedure, sedation, efficacy, and safety of DBE were evaluated. RESULTS Mean patient age was 12.9 years (range, 3-19 years). Patients ≤ 15 years old had general anesthesia. The procedures included the oral approach (n= 9), the anal approach (n= 4), and the ileostomal approach (n= 4). The mean procedure duration was 60 min. Accurate diagnosis was obtained in 7/8 cases (88%) of suspected CD. Only one case was diagnosed as indeterminate colitis, although the total small and large bowel was examined on DBE and pathology. Procedure tolerance was acceptable and recovery was uneventful in all cases. No serious complications were encountered. CONCLUSIONS With regard to the present limited IBD pediatric case series, DBE is a safe and effective procedure.

Abstract
Occult gastrointestinal bleeding, defined as bleeding that is unknown to the patient, is the most common form of gastrointestinal bleeding and can be caused by virtually any lesion in the gastrointestinal tract. Patients with occult gastrointestinal bleeding include those with fecal occult blood and iron-deficiency anemia (IDA). In men and postmenopausal women, IDA should be considered to be the result of gastrointestinal bleeding until proven otherwise. Indeed, the possibility of gastrointestinal tract malignancy in these patients means that gastrointestinal evaluation is nearly always indicated. Obscure gastrointestinal bleeding is defined as obvious bleeding from a difficult to identify source and is always recurrent. This form of bleeding accounts for approximately 5% of all cases of clinically evident gastrointestinal bleeding and is most commonly caused by bleeding from the small intestine. Capsule endoscopy and deep enteroscopy have had a major impact on the way that patients with occult and, in particular, obscure bleeding are managed. In this Review the causes, diagnostic evaluation and treatment of occult and obscure gastrointestinal bleeding are discussed.

Abstract
Current options for the diagnosis and management of small bowel lesions include push enteroscopy (PE), video capsule endoscopy (VCE), single-balloon enteroscopy (SBE), double-balloon enteroscopy (DBE), and intraoperative enteroscopy (IOE). IOE, the ultimate diagnostic and therapeutic modality for small bowel disorders, is a major surgical and endoscopic procedure. It should be reserved for cases that cannot be managed with others modalities because of the difficulties of the procedure and significant morbidity. The indication for IOE have diminished in recent years because of the development of VCE and DBE. IOE is reserved for patients with massive mid-gut bleeding, lesions not accessible by balloon enteroscopy, and lesions difficult or impossible to treat by balloon enteroscopy. There are special indications in Crohn disease and in Peutz-Jeghers syndrome. Our own results and a review of the literature are presented.

Abstract
Spiral enteroscopy is a new technique for endoscopic evaluation of the small bowel. Currently, more than 3000 cases have been performed worldwide. The Discovery SB device has been approved by the Food and Drug Administration and has been granted a CE mark. The technique is safe and effective for management and detection of small bowel pathology. Recent studies of spiral enteroscopy have demonstrated diagnostic yield, total time of procedure, and depth of insertion that compare favorably with double and single balloon enteroscopy. The strengths of spiral enteroscopy are rapid advancement in the small bowel and controlled, stable withdrawal that facilitates therapy. Future studies will be needed to compare competing technologies. Push enteroscopy is a readily available, safe and effective technique for detecting and treating proximal gut pathology. If performed without an overtube, complications are rare. Use of a dedicated push enteroscope with an overtube is generally reserved for specific indications in which a moderate increase in depth of insertion into the small bowel is required. When capsule endoscopy and deep small bowel enteroscopy are not available, push enteroscopy is a reasonable option with low risk and moderate yield. Push enteroscopy will remain an important part of the armamentarium of the modern endoscopist.

Abstract
BACKGROUND AND AIMS Until recently the study of small bowel was limited to the radiographic approach. This paper describes experience with the first 86 procedures evaluated and treated with the new technique of double-balloon enteroscopy (DBE). PATIENTS AND METHODS Between August 2005 and September 2006, DBE was conducted in consecutive patients. The characteristics of the patients, indications for the procedures, procedural parameters, and diagnostic yield are described here. All conventional treatment options were available. All the patients had previously undergone esophagogastroduodenoscopy and colonoscopy. RESULTS Eighty-six procedures in sixty-eight patients were carried out (41 women, 27 men; mean age 48.5 years, range 20-82). The most common indications were gastrointestinal bleeding (n = 40) and iron deficiency anemia (n = 7). The mean duration of the procedure was 63 (range 20-194) mins and 80 (range 20-150) minutes for the oral and anal routes, respectively. The mean depth of small-bowel insertion was 250 and 200 cm for the oral and anal routes, respectively. Impact in diagnosis and/or treatment was obtained in 50 patients (73.5%). The commonest findings in the 68 patients were angiodysplasia (n = 11), polyps (n = 8), nodular lymphoid hyperplasia (n = 5) and normal (n = 20). No major complications were observed. CONCLUSION DBE is a useful tool for the diagnosis and treatment of patients with small-bowel pathology in whom traditional methods have not been effective. In almost two-thirds of patients DBE was clinically useful for diagnosis and treatment. The complication rate with the procedure was very low.

Abstract
BACKGROUND Double-balloon enteroscopy (DBE) is a new technique, recently described by its innovator, and it is seen to be beneficial in the diagnosis and management of small-bowel disease. OBJECTIVE To evaluate this new technique in consecutive patients with suspected small-bowel disease. DESIGN Single-center prospective study. SETTING Tertiary referral hospital, conducted from July to December 2004. PATIENTS Forty consecutive patients with suspected small-bowel disease referred for DBE, mean age of 58 years (range, 14-89 years), 17 men. INTERVENTIONS Endoscopic biopsies or therapy was performed as clinically indicated. MAIN OUTCOME MEASUREMENTS Significant diagnostic input and therapeutic intervention based on clinical outcomes. RESULTS Indications included obscure GI bleeding (18), iron deficiency anemia (6), anemia of chronic disease (4), acute obscure GI bleeding (4), abdominal pain with other symptoms (4), Crohn's disease (3), and abdominal pain alone (1). Nineteen patients (47.5%) had a small-bowel finding, with 30 of 40 (75%) of the patients having a significant diagnostic input. Intervention was performed in 13 (32.5%) patients with success in 10 (77%). The only variable significantly associated with therapeutic success was a previous history of blood transfusions (p < 0.01). This was the only independent predictor identified by multiple logistic regression analysis (Odds ratio 13.5: 95% confidence interval [1.5, 120]). One perforation from contact diathermy occurred. In 10 attempts at total enteroscopy, none were successful. LIMITATIONS Nonblinded nonrandomized study. CONCLUSIONS These early data suggest DBE to be effective in the diagnosis and the therapy of small-bowel disease, particularly those patients with a history of blood transfusion.

Abstract
Occult gastrointestinal bleeding commonly manifests as iron deficiency anemia or fecal occult blood. Iron deficiency anemia results from chronic occult gastrointestinal bleeding. Evaluation of asymptomatic patients who have iron deficiency anemia or fecal occult blood usually should begin with investigation of the colon. Colonoscopy is preferred, but flexible sigmoidoscopy plus air contrast barium enema, or computed tomographic colonography may be acceptable in certain circumstances. If evaluation of the colon does not reveal a bleeding site, evaluation of the upper gastrointestinal tract is mandatory in patients who have iron deficiency anemia, and this should be considered in those who have fecal occult blood. In patients who have gastrointestinal symptoms, evaluation of the portion of the gastrointestinal tract from which the symptoms is derived should be pursued initially. The role of small intestinal investigation is controversial, and this probably should be reserved for patients who have iron deficiency anemia and persistent gastrointestinal symptoms or those who fail to respond to appropriate therapy. Celiac sprue should be considered as a potential cause of iron deficiency anemia in all patients. The treatment and prognosis of patients who have iron deficiency anemia or fecal occult blood depends on the gastrointestinal tract abnormality(ies) identified. Those without identifiable bleeding sites generally respond to conservative management and have a favorable prognosis. On the other hand, the outlook is poorer for patients with refractory occult blood loss or those who have vascular ectasias. Both groups of patients are clinically challenging and require a focused and experienced team approach to diagnosis and therapy.

Abstract
With the heterogeneous clinical presentation of IBD, endoscopy plays an integral role in the initial diagnosis of Crohn's disease. Although radiographic tests are often supplemental in the evaluation of Crohn's disease, they previously had been the only modality available allowing for visualization of much of the small bowel. The advent of small bowel endoscopy allows for direct visualization, and often biopsy, of the small bowel, allowing for confirmation of diagnosing and extent of involvement. Currently, the only mode for obtaining biopsies from beyond the ligament of Treitz is via push enteroscopy or intraoperative enteroscopy. Knowing the extent of disease can also help explain recalcitrant symptoms or lack of response to certain therapies. With the advent of capsule endoscopy, endoscopic visualization of the entire small intestine is now possible with a relatively noninvasive test. Further advancements in capsule endoscopy may relegate push enteroscopy and intraoperative enteroscopy to those cases in which biopsies or therapy are required. In the future, total enteroscopy with new enteroscopes may become more widely available, allowing biopsies and therapy in all segments of the small intestine, without the need for operative intervention.
