“…The NaviAid AB (Advancing Balloon) device (SMART Medical Systems, Ra’anana, Israel) is a balloon-assisted enteroscopy device that uses a through-the-scope balloon to allow deep intubation of the small intestine with the use of a standard colonoscope. This system has a short learning curve and can be used without the assistance of another endoscopist 37 . More studies are required in order to evaluate its diagnostic yield compared with CE findings.…”

Background and study aims: Several studies have evaluated the utility of double-balloon enteroscopy (DBE) and capsule endoscopy (CE) for patients with small-bowel disease showing inconsistent results. The aim of this study was to determine the sensitivity and specificity of overtube-assisted enteroscopy (OAE) as well as the diagnostic concordance between OAE and CE for small-bowel polyps and tumors. Patients and methods: We conducted a systematic review and meta-analysis of studies in which the results of OAE were compared with the results of CE for the evaluation of small-bowel polyps and tumors. When data for surgically resected lesions were available, the histopathological results of OAE and surgical specimens were compared. The sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio for the diagnosis of small-bowel polyps and tumors were analyzed. Secondarily, the rates of diagnostic concordance and discordance between OAE and CE were calculated. Results: There were 15 full-length studies with a total of 821 patients that met the inclusion criteria. The pooled sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio were as follows: 0.89 (95 % confidence interval [CI] 0.84 – 0.93), with heterogeneity χ2 = 41.23 (P = 0.0002) and inconsistency (I 2) = 66.0 %; 0.97 (95 %CI 0.95 – 0.98), with heterogeneity χ2 = 45.27 (P = 0.07) and inconsistency (I 2) = 69.1 %; 16.61 (95 %CI 3.74 – 73.82), with heterogeneity Cochrane’s Q = 225.19 (P < 0.01) and inconsistency (I 2) = 93.8 %; and 0.14 (95 %CI 0.05 – 0.35), with heterogeneity Cochrane’s Q = 81.01 (P < .01) and inconsistency (I 2) = 82.7 %, respectively. A summary receiver operating characteristic curve (SROC) curve was constructed, and the area under the curve (AUC) was 0.97. Conclusion: OAE is an accurate test for the detection of small-bowel polyps and tumors. OAE and CE have a high diagnostic concordance rate for small-bowel polyps and tumors.This study was registered in the PROSPERO international database () with the study number CRD42015016000.

“…Recently, a ‘through‐the‐scope’ balloon system (such as the NaviAid system by Smart Medical Systems Ltd, Ra'anana, Israel) has been introduced to enable on demand and ready‐to‐use enteroscopy during standard upper or lower endoscopy . However, the evidence on this novel approach is still limited.…”

Over the last decade, impressive technological advances have occurred in ultrasonography and small‐bowel endoscopy. Nowadays, endoscopic ultrasonography is an essential diagnostic tool and a therapeutic weapon for pancreatobiliary disorders. Capsule endoscopy and device‐assisted enteroscopy have quickly become the reference standard for the diagnosis of small‐bowel luminal diseases, thereby leading to radical changes in diagnostic and therapeutic pathways. We herein provide an up‐to‐date overview of the latest advances in endoscopic ultrasonography and small‐bowel endoscopy, focusing on the emerging paradigms and technological innovations that might improve clinical practice in the near future.

“…A new prototype endoscope with a motor driven, force controlled rotating distal spiral segment (Olympus) demonstrated feasibility in patients, allowing complete enteroscopy with a single oral approach in some of them [45] , [46] . Recently, balloon assisted enteroscopy (Pentax/Smart Medical) with a standard colonoscope assisted by a through the scope (TTS) balloon has been reported [47] . After inflation of the advanced balloon catheter the endoscope is pushed forward over the catheter.…”

Flexible gastro-intestinal (GI) endoscopy is an integral diagnostic and therapeutic tool in clinical gastroenterology. High quality standards for safety, patients' comfort, and efficiency have already been achieved. Clinical challenges and technical approaches are discussed in this short review.Image enhanced endoscopy for further characterization of mucosal and vascular patterns includes dye-spray or virtual chromoendoscopy. For confocal laser endoscopy, endocytoscopy, and autofluorescence clinical value has not yet been finally evaluated. An extended viewing field provided by additional cameras in new endoscopes can augment detection of polyps behind folds. Attachable caps, flaps, or balloons can be used to flatten colonic folds for better visualization and stable position.Variable stiffness endoscopes, radiation-free visualization of endoscope position, and different overtube devices help reducing painful loop formation in clinical routine. Computer assisted and super flexible self-propelled colonoscopes for painless sedation-free endoscopy need further research. Single-use devices might minimize the risk of infection transmission in the future.Various exchangeable accessories are available for resection, dissection, tunneling, hemostasis, treatment of stenosis and closure of defects, including dedicated suturing devices. Multiple arm flexible devices controlled via robotic platforms for complex intraluminal and transmural endoscopic procedures require further improvement.
