Abstract
Device-assisted enteroscopy (DAE), balloon-assisted enteroscopy (BAE) in particular, has become a routine endoscopic procedure which has revolutionized our approach to small-bowel disease. Evidence demonstrating the efficacy and safety of BAE spans over 22-years of experience, making it an established pillar of minimally invasive care. The robust evidence for BAE's safety and efficacy has now been incorporated into international clinical guidelines, technical reviews, benchmarking performance measures and curricula. The more recently introduced motorized spiral enteroscopy (MSE) which had replaced the previous manual version, abruptly ended its 7-year stint in clinical practice, when it was withdrawn and recalled from the market by its manufacturing company in July 2023, due to several associated serious adverse events (including fatalities). This article, written by the original developer of double-balloon enteroscopy (DBE) and other recognized international experts and pioneers in this field, focuses mainly on the technical aspects, evolving indications, and equipment-related technological advances. Despite the very recent withdrawal of MSE from clinical practice, for completeness, this technology and its technique is still briefly covered here, albeit importantly, along with a short description of reported, associated, serious adverse events which have contributed to its withdrawal/recall from the market and clinical practice.

Abstract
The advent of video capsule endoscopy into clinical routine more than 15 years ago led to a substantial change in the diagnostic approach to patients with suspected small bowel diseases, often indicating a deep enteroscopy procedure for diagnostical confirmation or endoscopic treatment. Device assisted enteroscopy was developed in 2001 and for the first time established a practicable, safe and effective method for evaluation of the small bowel. Currently with double-balloon enteroscopy, single-balloon enteroscopy and spiral enteroscopy three different platforms are available in clinical routine. Summarizing, double-balloon enteroscopy seems to offer the deepest insertion depth to the small bowel going hand in hand with the disadvantage of a longer procedural duration. Manual spiral enteroscopy seems to be a faster procedure but without reaching the depth of the DBE in currently available data. Finally, single-balloon enteroscopy seems to be the least complicated procedure to perform. Despite substantial improvements in the field of direct enteroscopy, even nowadays deep endoscopic access to the small bowel with all available methods is still a complex procedure, cumbersome and time-consuming and requires high endoscopic skills. This review will give an overview of the currently available techniques and will further discuss the role of the upcoming new technology of the motorized spiral enteroscopy (PowerSpiral).

Abstract
After more than 15 years since its introduction into clinical practice, indications for device-assisted enteroscopy have greatly expanded. Alongside the consolidated indications such as the diagnosis and treatment of small bowel bleeding, Crohn's disease, hereditary polyposis, small-bowel tumors and complicated celiac disease, device-assisted enteroscopy is nowadays largely used to perform endoscopic retrograde cholangiopancreatography in patients with altered anatomy, stent placement, retrieval of foreign bodies, direct insertion of jejunal feeding tubes, and in selected cases of incomplete colonoscopy. This has been made possible by the technical improvements of the enteroscopes and accessories and by the widespread use of the method. Device-assisted enteroscopy endotherapy currently offers a safe and effective alternative to major surgery and often represents the preferred option for treatment of small-bowel pathology. Its safety profile is favourable even in the elderly patient, provided that it is performed in high-volume and experienced centers. The evolution of the enteroscopy technique is a challenge for the future and could be facilitated by the new enteroscopes models. These prototypes need a thorough clinical and safety assessment especially for the complex therapeutic procedures. Large prospective, multicenter studies should be performed to assess whether the use of device-assisted enteroscopy leads to improved patients' long-term outcomes.

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
The advent of deep enteroscopy (DE) has dramatically changed diagnostic and therapeutic approaches to small bowel diseases. Unlike capsule endoscopy, which is unable to obtain biopsies or treat a disease, DE techniques have diagnostic and therapeutic capabilities. Double-balloon enteroscopy (DBE) was introduced in 2001, and single-balloon enteroscopy (SBE) and spiral enteroscopy (SE) were subsequently developed for small bowel investigation. In published reports comparing these different enteroscopy techniques, most comparative parameters (depth of insertion, complications, learning curve, diagnostic yield, and therapeutic yield) were comparable among DBE, SBE, and SE. However, the procedure duration appears to be shorter for SE than for DBE and SBE. The rate of complete enteroscopy is clearly superior for DBE, compared with SE and SBE. Because these results do not indicate an increase in diagnostic or therapeutic yield, the clinical impact of complete enteroscopy remains controversial. According to previous studies, the three DE methods seem to be equally effective and safe in the clinical setting. Although larger randomized controlled trials are needed to evaluate the procedural characteristics and clinical impact, the selection of an enteroscopic technique should be based on availability and the endoscopist's experience.

Abstract
Within the last decade, the technological development improved the diagnostic work-up of small bowel diseases. In addition to abdominal ultrasound and radiological methods, the importance of endoscopy is increasing. Nowadays, five nonsurgical flexible endoscopy techniques are available for small bowel endoscopy: push enteroscopy and balloon-guided enteroscopy for evaluation of the proximal small bowel, balloon-assisted enteroscopy using two balloons (double-balloon enteroscopy) or one balloon (single-balloon enteroscopy), and spiral enteroscopy for evaluation of the deep small bowel. Intraoperative enteroscopy has become a reserve method.

Abstract
BACKGROUND Double-balloon enteroscopy (DBE) is an established method in diagnostic and therapeutic small-bowel enteroscopy. OBJECTIVE Spiral enteroscopy (SE) appears to be a promising new technique. A randomized, prospective study was conducted to compare both methods. DESIGN Randomized, prospective study. SETTING Single tertiary referral center. PATIENTS Between September 2009 and March 2011, 26 patients with suspected mid-GI disorders completed the study. INTERVENTIONS Patients were randomly assigned to DBE or SE. The oral examination was conducted first, with the deepest point reached being marked with India ink. An additional anal examination followed the day after, with the aim of reaching the ink mark. MAIN OUTCOME MEASUREMENTS The primary endpoint of the study was the rate of complete enteroscopies achieved. RESULTS The rate of complete enteroscopies with DBE was 12 times the rate achieved with SE (8% in the SE group and 92% in the DBE group; P = .002). With regard to the secondary study criteria, much longer examination times but greater depths of insertion were associated with DBE. There were no statistically significant differences in the diagnostic or therapeutic outcomes between the SE and DBE groups (diagnostic yield, P = .428; therapeutic yield, P = 1.0; Fisher exact test). One perforation occurred during an anal examination as a relevant adverse event in SE. LIMITATIONS Single-center study, small sample size. CONCLUSION SE does not represent an alternative to DBE with regard to the depth of insertion or the rate of complete enteroscopies achieved. However, SE is advantageous in that it involves significantly shorter examination times. Further technical improvements will be necessary before SE can compete with DBE for complete enteroscopies.

Abstract
Nowadays, 5 nonsurgical flexible endoscopic techniques are available for small bowel endoscopy: push enteroscopy (PE), balloon-assisted enteroscopy using 2 balloons (double-balloon enteroscopy [DBE]) or 1 balloon (single-balloon enteroscopy [SBE]), balloon-guided enteroscopy (BGE), and spiral enteroscopy (SE). PE is a cost-saving, easy, and fast procedure for the examination of the proximal jejunum, but for a deep small bowel endoscopy, the other flexible enteroscopic techniques are required. BGE does not play a considerable role in deep small bowel endoscopy. DBE is the oldest flexible enteroscopic technique. Actually, the balloon-assisted enteroscopy (BAE) techniques with one balloon (SBE) or two balloons (DBE) are the mainly used techniques. DBE has become established throughout the world for diagnostic and therapeutic examinations of the small bowel and is now used universally in clinical routine work. DBE is still regarded as the gold standard nonsurgical procedure for deep small bowel endoscopy, because it provides the highest rates of complete enteroscopy, which becomes increasingly useful. The recently introduced SE technique represents a promising method but still needs technical improvement. Larger prospective studies on SE and prospective studies comparing the 3 systems (DBE, SBE, SE) are awaited before conclusive assessments can be made.

Abstract
BACKGROUND Until now, the insertion depth of the enteroscope during double-balloon enteroscopy (DBE) could only be estimated. However, the currently available methods have limitations, and development of newer, simple, and accurate modalities is needed. OBJECTIVE To evaluate the accuracy of a novel method for evaluation of enteroscope insertion depth during DBE. DESIGN Prospective, single-center cohort study. SETTING Tertiary referral university hospital. PATIENTS Fifty-one patients who had lesions found during 41 antegrade and 10 retrograde DBEs and treated by surgery were enrolled in this study. INTERVENTIONS The length of the ligament of Treitz/ileocecal valve lesion was estimated by adding the forward enteroscope length during each cycle of passage and by calculating the overtube insertion length (every 5 cm of overtube advancement means 40 cm of enteroscope advancement based on preliminary observations) during DBE, respectively, and was evaluated at surgery. MAIN OUTCOME MEASUREMENTS The length from the ligament of Treitz/ileocecal valve to the lesion. RESULTS Surgical evaluation was used as the standard. Regardless of insertion route, the mean difference from surgery in evaluation of enteroscope insertion length between using the enteroscope method and the overtube method was 19 cm (range 0-50 cm) and 17 cm (range 0-60 cm), respectively (P > .05). LIMITATIONS Small number of patients with a case series study design. CONCLUSIONS Calculating the length of the overtube passage is accurate, and it is simple to estimate the insertion depth of the enteroscope during DBE, which is useful in clinical practice.

Abstract
Double balloon enteroscopy (DBE) is a new technique, first published and introduced into clinical practice in 2001 by Yamamoto, the inventor of this outstanding method. DBE allows complete visualization, biopsy and treatment of the small bowel. Nowadays, we have some experience of this method for evaluation of the complication rate. Severe complications are described in 1%-1.7% of patients. Acute pancreatitis is a rare complication of the investigation. The incidence of acute pancreatitis after diagnostic DBE is 0.3% in most studies. More than 50 cases of acute pancreatitis have been described in the literature so far. On the contrary, hyperamylasemia after DBE seems to be a rather common condition. Association with acute pancreatitis is supposed to be possible, but not obligatory. The causal mechanism of post-DBE acute pancreatitis is uncertain, and there are several theories in the literature. The most probable cause seems to be a mechanical straining of the endoscope with over-tube on the pancreas or in the papillary area.

Abstract
Gastrointestinal bleeding can be obscure or occult (OGIB), the causes and diagnostic approach will be discussed in this editorial. The evaluation of OGIB consists on a judicious search of the cause of bleeding, which should be guided by the clinical history and physical findings. The standard approach to patients with OGIB is to directly evaluate the gastrointestinal tract by endoscopy, abdominal computed tomography, angiography, radionuclide scanning, capsule endoscopy. The source of OGIB can be identified in 85%-90%, no bleeding sites will be found in about 5%-10% of cases. Even if the bleedings originating from the small bowel are not frequent in clinical practice (7.6% of all digestive haemorrhages, in our casuistry), they are notoriously difficult to diagnose. In spite of progress, however, a number of OGIB still remain problematic to deal with at present in the clinical context due to both the difficulty in exactly identifying the site and nature of the underlying source and the difficulty in applying affective and durable diagnostic approaches so no single technique has emerged as the most efficient way to evaluate OGIB.

Abstract
Capsule endoscopy and balloon-assisted enteroscopy, have revolutionized our approach to the diagnosis and management of patients with obscure gastrointestinal bleeding, largely replacing intraoperative enteroscopy and conventional barium studies. Despite its limitations, capsule endoscopy may well be the most reasonable initial diagnostic strategy to evaluate most patients with obscure gastrointestinal bleeding, leaving balloon-assisted enteroscopy in reserve as a complementary tool. This article reviews the data on enteroscopy, with particular emphasis on the use of capsule endoscopy and balloon-assisted enteroscopy for the diagnosis and management of patients with obscure gastrointestinal bleeding.
