Background and Aim: We aimed to prospectively determine patient burden and patient preference for magnetic resonance enteroclysis, capsule endoscopy and balloon‐assisted enteroscopy in patients with suspected or known Crohn's disease (CD) or occult gastrointestinal bleeding (OGIB). Methods: Consecutive consenting patients with CD or OGIB underwent magnetic resonance enteroclysis, capsule endoscopy and balloon‐assisted enteroscopy. Capsule endoscopy was only performed if magnetic resonance enteroclysis showed no high‐grade small bowel stenosis. Patient preference and burden was evaluated by means of standardized questionnaires at five moments in time. Results: From January 2007 until March 2009, 76 patients were included (M/F 31/45; mean age 46.9 years; range 20.0–78.4 years): 38 patients with OGIB and 38 with suspected or known CD. Seventeen patients did not undergo capsule endoscopy because of high‐grade stenosis. Ninety‐five percent (344/363) of the questionnaires were suitable for evaluation. Capsule endoscopy was significantly favored over magnetic resonance enteroclysis and balloon‐assisted enteroscopy with respect to bowel preparation, swallowing of the capsule (compared to insertion of the tube/scope), burden of the entire examination, duration and accordance with the pre‐study information. Capsule endoscopy and magnetic resonance enteroclysis were significantly preferred over balloon‐assisted enteroscopy for clarity of explanation of the examination, and magnetic resonance enteroclysis was significantly preferred over balloon‐assisted enteroscopy for bowel preparation, painfulness and burden of the entire examination. Balloon‐assisted enteroscopy was significantly favored over magnetic resonance enteroclysis for insertion of the scope and procedure duration. Pre‐ and post‐study the order of preference was capsule endoscopy, magnetic resonance enteroclysis and balloon‐assisted enteroscopy. Conclusion: Capsule endoscopy was preferred to magnetic resonance enteroclysis and balloon‐assisted enteroscopy; it also had the lowest burden. Magnetic resonance enteroclysis was preferred over balloon‐assisted enteroscopy for clarity of explanation of the examination, bowel preparation, painfulness and burden of the entire examination, and balloon‐assisted enteroscopy over magnetic resonance enteroclysis for scope insertion and study duration. 相似文献

Enteroscopy, defined as direct visualization of the smallbowel with the use of a fiberoptic or capsule endoscopy, has progressed considerably over the past severalyears. The need for endoscopic access to improvediagnosis and treatment of small bowel disease hasled to the development of novel technologies one ofwhich is noninvasive, the video capsule, and a type of invasive technique, the deviceassisted enteroscopy.In particular, the device-assisted enteroscopy consiststhen of three different types of instruments all able toallow, in skilled hands, to display partially or throug-hout its extension (if necessary) the small intestine.Newer devices, double balloon, single balloon and spiral endoscopy, are just entering clinical use. The aim of this article is to review recent advances in small bowelenteroscopy, focusing on indications, modifications toimprove imaging and techniques, pitfalls, and clinical applications of the new instruments. With new technologies, the trials and tribulations of learning new endo-scopic skills and determining their role in the diagnosisand treatment of small bowel disease come. Identification of small bowel lesions has dramatically improved.Studies are underway to determine the best strategy toapply new enteroscopy technologies for the diagnosisand management of small bowel disease, particularly obscure bleeding. Vascular malformations such as angiectasis and small bowel neoplasms as adenocar cinomaor gas trointestinal stromal tumors. Complete entero-scopy of the small bowel is now possible. However, because of the length of the small bowel, endoscopic examination and the rapeutic maneuvers require significant skill, radiological assistance, the use of deep sedation with the assistance of the anesthetist. Prospective ran-domized studies are needed to guide diagnostic testing and the rapy with these new endoscopic techniques. 相似文献

Since the introduction of capsule endoscopy and, later, balloon enteroscopy in clinical practice, endoscopic examination of the small bowel has dramatically improved. For the first time, it is possible to diagnose the entire small bowel without the need for laparotomy and intraoperative enteroscopy. These methods revolutionized the field of small bowel diagnostics and therapy and have become part of daily clinical practice. This article provides a review of small bowel enteroscopy techniques. 相似文献

Small bowel tuberculosis is sometimes encountered in oriental countries, and because its symptoms are vague and present a nonspecific pattern, confirmative diagnosis is difficult to achieve. In 2001, two new innovative endoscopic techniques for the small bowel, video capsule endoscopy and double balloon enteroscopy, were introduced, thus advancing the diagnostic technology for small bowel disorders. Our asymptomatic patient with small bowel tuberculosis was diagnosed definitively using the combination of video capsule endoscopy and double balloon enteroscopy. The number of such cases will increase when those procedures become more widely used. At present, the endoscopic view of small bowel tuberculosis is difficult to differentiate from Crohn's disease and drug-induced enteropathy, but from now on it will be possible to distinguish them utilizing endoscopic and fluoroscopic images. On the basis of the characteristics of small bowel tuberculosis with its endoscopic images, referring to our case report and previous literature, we report a topical diagnostic procedure, the combination of video capsule endoscopy and double balloon enteroscopy. 相似文献

BACKGROUND: Small bowel mass lesions (SBML) are a relatively common cause of obscure gastrointestinal bleeding (OGIB). Their detection has been limited by the inability to endoscopically examine the entire small intestine. This has changed with the introduction of capsule endoscopy (CE) and double balloon enteroscopy (DBE) into clinical practice. STUDY AIM: To evaluate the detection of SBML by DBE and CE in patients with OGIB who were found to have SBML by DBE and underwent both procedures. METHODS: A retrospective review of a prospectively collected database of all patients undergoing DBE for OGIB at seven North American tertiary centers was performed. Those patients who were found to have SBML as a cause of their OGIB were further analyzed. RESULTS: During an 18 month period, 183 patients underwent DBE for OGIB. A small bowel mass lesion was identified in 18 patients. Of these, 15 patients had prior CE. Capsule endoscopy identified the mass lesion in five patients; fresh luminal blood with no underlying lesion in seven patients, and non-specific erythema in three patients. Capsule endoscopy failed to identify all four cases of primary small bowel adenocarcinoma. CONCLUSIONS: Double balloon enteroscopy detects small bowel mass lesions responsible for OGIB that are missed by CE. Additional endoscopic evaluation of the small bowel by DBE or intraoperative enteroscopy should be performed in patients with ongoing OGIB and negative or non-specific findings on CE. 相似文献

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. 相似文献

Spiral enteroscopy is the newest of the deep enteroscopy techniques. The current technique employs an overtube with a raised spiral at the distal end to pleat the small intestine and achieve deep small bowel intubation. Although spiral enteroscopy is a novel technique, the learning curve is comparable to the balloon enteroscopy techniques. There is some evidence of improved speed of spiral enteroscopy procedures with superior control compared to the balloon endoscopy technologies. Altered surgical anatomy deep enteroscopy has been shown to have similar safety and efficacy to competitive technologies, particularly in cases of Roux-en-Y ERCP cases. Spiral enterosopy is safe and effective for deep small bowel enteroscopy and diagnostic yield and therapeutic yields are similar to alternate technologies. There are bright future applications of the technology with enteroscopes and an integrated spiral. Spiral enteroscopy is an advanced technique that can be performed by any skilled endoscopist. 相似文献

The evaluation of the small bowel in patients with suspected or established IBD is generally performed by radiologic techniques. Capsule endoscopy and balloon enteroscopy may offer additional advantages in the evaluation of small bowel inflammation in patients with suspected small bowel involvement but negative prior radiologic evaluation. This review summarizes the current clinical status of capsule and balloon enteroscopy in patients with suspected or established IBD. 相似文献

Management of small bowel diseases has evolved since the advent of capsule endoscopy (CE) and balloon‐assisted enteroscopy (BAE). One of the most common indications for enteroscopy is obscure gastrointestinal bleeding (OGIB), followed by small bowel stenosis, tumors, and inflammatory bowel disease. Although enteroscopes have been regarded as useful tools, correct guidelines are required to ensure that we manipulate these enteroscopes safely and efficiently in clinical practice. Herein, the Japanese Gastroenterological Endoscopy Society has developed ‘Clinical Practice Guidelines for Enteroscopy’ in collaboration with the Japanese Society of Gastroenterology, the Japanese Gastroenterological Association, and the Japanese Association for Capsule Endoscopy. These guidelines are based on the evidence available until now, but small bowel endoscopy is a relatively new technology, so the guidelines include recommendations based on a consensus reached among experts when the evidence has not been considered sufficient. These guidelines were not designed to be disease‐based, but focus on how we should use small bowel CE and BAE in everyday clinical practice. 相似文献

Crohn’s disease (CD) is a chronic inflammatory condition of the gastrointestinal tract resulting in inflammation, stricturing and fistulae secondary to transmural inflammation. Diagnosis relies on clinical history, abnormal laboratory parameters, characteristic radiologic and endoscopic changes within the gastrointestinal tract and most importantly a supportive histology. The article is intended mainly for the general gastroenterologist and for other interested physicians. Management of small bowel CD has been suboptimal and limited due to the inaccessibility of the small bowel. Enteroscopy has had a significant renaissance recently, thereby extending the reach of the endoscopist, aiding diagnosis and enabling therapeutic interventions in the small bowel. Radiologic imaging is used as the first line modality to visualise the small bowel. If the clinical suspicion is high, wireless capsule endoscopy (WCE) is used to rule out superficial and early disease, despite the above investigations being normal. This is followed by push enteroscopy or device assisted enteroscopy (DAE) as is appropriate. This approach has been found to be the most cost effective and least invasive. DAE includes balloon-assisted enteroscopy, [double balloon enteroscopy (DBE), single balloon enteroscopy (SBE) and more recently spiral enteroscopy (SE)]. This review is not going to cover the various other indications of enteroscopy, radiological small bowel investigations nor WCE and limited only to enteroscopy in small bowel Crohn’s. These excluded topics already have comprehensive reviews. Evidence available from randomized controlled trials comparing the various modalities is limited and at best regarded as Grade C or D (based on expert opinion). The evidence suggests that all three DAE modalities have comparable insertion depths, diagnostic and therapeutic efficacies and complication rates, though most favour DBE due to higher rates of total enteroscopy. SE is quicker than DBE, but lower complete enteroscopy rates. SBE has quicker procedural times and is evolving but the least available DAE today. Larger prospective randomised controlled trial’s in the future could help us understand some unanswered areas including the role of BAE in small bowel screening and comparative studies between the main types of enteroscopy in small bowel CD. 相似文献

Investigation of the small bowel in gastrointestinal bleeding--enteroscopy and capsule endoscopy 总被引:3,自引:0,他引:3
The last frontier in luminal endoscopy has been conquered. Bleeding lesions in the small intestine can present a frustrating clinical problem, but recent advances have made investigating the small bowel easier and less invasive. Capsule endoscopy and double balloon enteroscopy are two new technologies that promise to lower the barrier to evaluation of the entire small intestine. Recent studies show that capsule endoscopy improves outcomes in patients who have OGIB. Although outcome studies regarding double balloon enteroscopy have not been performed, the opportunity to treat lesions throughout the small bowel without resorting to surgery is a tremendous advance. These improvements suggest that the corner may have been turned in the diagnosis and management of small bowel bleeding. Perhaps to the next generation of gastroenterologists, small bowel bleeding will not be obscure. 相似文献

Small bowel pseudomelanosis is a rarely reported clinical entity characterized by brown pigmentation of small bowel mucosa. The authors describe two cases, both with iron deficiency anemia, one of an 81‐year‐old female patient submitted for capsule endoscopy that revealed a brown pigmentation of all small bowel mucosa and another of an 81‐year‐old male whose retrograde double‐balloon enteroscopy revealed a diffuse brown pattern of small bowel mucosa. Ileal biopsies confirmed intense iron deposition in the macrophages of the lamina propria. Both patients were on oral iron therapy and the second one had a previous double‐balloon enteroscopy, 2 years earlier, which revealed only ileal angiodysplasias. These two cases demonstrate the importance of two new endoscopic methods for diagnosis of small bowel pseudomelanosis, the rarity of such an entity and its close relation with oral iron therapy. 相似文献

Obscure gastrointestinal bleeding(OGIB) is defined as recurrent or persistent bleeding or presence of iron deficiency anaemia after evaluation with a negative bidirectional endoscopy. OGIB accounts for 5% of gastrointestinal bleeding and presents a diagnostic challenge. Current modalities available for the investigation of OGIB include capsule endoscopy, balloon assisted enteroscopy, spiral enteroscopy and computed tomography enterography. These modalities overcome the limitations of previous techniques. Following a negative bidirectional endoscopy, capsule endoscopy and double balloon enteroscopy remain the cornerstone of investigation in OGIB given their high diagnostic yield. Longterm outcome data in patients with OGIB is limited, but is most promising for capsule endoscopy. This article reviews the current literature and provides an overview of the clinical evaluation of patients with OGIB, available diagnostic and therapeutic modalities and longterm clinical outcomes. 相似文献

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). 相似文献

Sixty five of 70 consecutive patients with undiagnosed gastrointestinal blood loss were examined using the new technique of small bowel enteroscopy. Using a balloon driven sonde enteroscope (SIF-SW) extended views of the small bowel were obtained as far as the distal ileum. Medium length of small bowel examined was 140 cm (range (30-200 cm). All patients studied had a normal upper gastrointestinal endoscopy. Nineteen (41%) of 46 anaemic rheumatoid arthritis patients taking non-steroidal antiinflammatory drugs (NSAID) and three (27%) of 11 patients with unexplained iron deficiency, were found to have small bowel lesions to account for their anaemia. Small bowel lesions were found in a further three of eight (37%) patients with acute gastrointestinal bleeding. The procedure failed or was terminated in five patients. Small bowel enteroscopy has considerable potential in the investigation of undiagnosed gastrointestinal blood loss and deserves more widespread application. 相似文献
