Abstract
Metastatic small bowel cancers are extremely rare in clinical practice. Primary appendiceal adenocarcinoma with gastrointestinal metastasis is seldom reported in the literature. Here, we describe the case of an 80-year-old male patient with primary appendiceal adenocarcinoma, who presented to China Medical University Hospital with mid-gastrointestinal tract bleeding. Capsule endoscopy revealed stenotic bowel lumen, but the capsule was retained in the distal duodenum. Double-balloon enteroscopy demonstrated erosive and erythematous mucosa in the region of capsule retention. The retained capsule was retrieved successfully by using an electrosurgical snare. Histological examination and immunohistochemical staining of the biopsy specimen from the duodenal lesion strongly supported the diagnosis of metastatic appendiceal adenocarcinoma.

Zhang ZH, Qiu CH, Li Y. Different roles of capsule endoscopy and double-balloon enteroscopy in obscure small intestinal diseases. World J Gastroenterol 2015; 21:7297-7304. [PMID: 26109818 PMCID: PMC4476893 DOI: 10.3748/wjg.v21.i23.7297] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2015] [Revised: 02/27/2015] [Accepted: 04/28/2015] [Indexed: 02/06/2023] Open
Abstract
AIM: To compare the roles of capsule endoscopy (CE) and double-balloon enteroscopy (DBE) in the diagnosis of obscure small bowel diseases.
METHODS: From June 2009 to December 2014, 88 patients were included in this study; the patients had undergone gastroscopy, colonoscopy, radiological small intestinal barium meal, abdominal computed tomography or magnetic resonance imaging scan and mesenteric angiography, but their diagnoses were still unclear. The patients with gastrointestinal obstructions, fistulas, strictures, or cardiac pacemakers, as well as pregnant women, and individuals who could not accept the capsule-retention or capsule-removal surgery were excluded. Patients with heart, lung and other vital organ failure diseases were also excluded. Everyone involved in this study had undergone CE and DBE. The results were divided into: (1) the definite diagnosis (the diagnosis was confirmed at least by one of the biopsy, surgery, pathology or the drug treatment effects with follow-up for at least 3 mo); (2) the possible diagnosis (a possible diagnosis was suggested by CE or DBE, but not confirmed by the biopsy, surgery or follow-up drug treatment effects); and (3) the unclear diagnosis (no exact causes were provided by CE and DBE for the disease). The detection rate and the diagnostic yield of the two methods were compared. The difference in the etiologies between CE and DBE was estimated, and the different possible etiologies caused by the age groups were also investigated.
RESULTS: CE exhibited a better trend than DBE for diagnosing scattered small ulcers (P = 0.242, Fisher’s test), and small vascular malformations (χ2 = 1.810, P = 0.179, Pearson χ2 test), but with no significant differences, possible due to few cases. However, DBE was better than CE for larger tumors (P = 0.018, Fisher’s test) and for diverticular lesions with bleeding ulcers (P = 0.005, Fisher’s test). All three hemangioma cases diagnosed by DBE in this study (including sponge hemangioma, venous hemangioma, and hemangioma with hamartoma lesions) were all confirmed by biopsy. Two parasite cases were found by CE, but were negative by DBE. This study revealed no obvious differences in the detection rates (DR) of CE (60.0%, 53/88) and DBE (59.1%, 52/88). However, the etiological diagnostic yield (DY) difference was apparent. The CE diagnostic yield was 42.0% (37/88), and the DBE diagnostic yield was 51.1% (45/88). Furthermore, there were differences among the age groups (χ2 = 22.146, P = 0.008, Kruskal Wallis Test). Small intestinal cancer (5/6 cases), vascular malformations (22/29 cases), and active bleeding (3/4 cases) appeared more commonly in the patients over 50 years old, but diverticula with bleeding ulcers were usually found in the 15-25-year group (4/7cases). The over-25-year group accounted for the stromal tumors (10/12 cases).
CONCLUSION: CE and DBE each have their own advantages and disadvantages. The appropriate choice depends on the patient’s age, tolerance, and clinical manifestations. Sometimes CE followed by DBE is necessary.

Abstract
Patients with persistent, recurrent, or intermittent bleeding from the gastrointestinal (GI) tract for which no definite cause has been identified by initial esophagogastroduodenoscopy, colonoscopy, or conventional radiologic evaluation are considered to have an obscure GI bleeding (OGIB). The diagnosis and management of patients with OGIB is challenging, often requiring extensive and expensive workups. The main objective is the identification of the etiology and site of bleeding, which should be as rapidly accomplished as possible, in order to establish the most appropriate therapy. The introduction of capsule endoscopy and double balloon enteroscopy and the recent improvements in CT and MRI techniques have revolutionized the approach to patients with OGIB, allowing the visualization of the entire GI tract, particularly the small bowel, until now considered as the "dark continent" . In this article we review and compare the radiologic and endoscopic examinations currently used in occult and OGIB, focusing on diagnostic patterns, pitfalls, strengths, weaknesses, and value in patients' management.

Abstract
BACKGROUND AND AIM Capsule endoscopy (CE) has been proven to be a sensitive and a safe tool for the examination of the small bowel. However, careful patient selection is required to avoid complications, primarily capsule retention. The aims of this study were to evaluate the rate of capsule retention in patients with suspected chronic small bowel obstruction and to analyze the role and the impact of subsequent surgical intervention. METHODOLOGY Fifteen patients referred for CE with a clinical picture suggestive of chronic small bowel obstruction and with negative imaging studies were retrospectively analyzed. RESULTS Capsule retention occurred in three (20%) patients who developed symptoms of subacute obstruction and subsequently underwent surgery. Radiation enteritis, Crohn's disease, and an ileal tumor were demonstrated as the causes of the capsule retention in these patients. Surgical removal of the retained capsule was performed and the underlying small bowel disease was treated. CONCLUSION Capsule retention is a frequent complication of CE in patients with symptoms of chronic small bowel obstruction. Surgery, with the removal of the retained capsule, is proven to be beneficial in identifying the location of, and treating, the underlying disease in these patients.

Abstract
PURPOSE The aim of our study was to determine the safety and usefulness of capsule endoscopy (CE) in pediatric patients. METHODS We prospectively examined children (aged 10-18 years) with suspected small bowel disease and recorded capsule transit times, findings, and complications. RESULTS We performed 19 CE examinations in 12 patients (median age 11.8 years; range 10-18 years). One of the two patients with obscure gastrointestinal bleeding (OGIB), a 14-year-old girl whose OGIB occurred after cord-blood transplantation due to leukemia, was diagnosed with thrombotic microangiopathy. Repeated CE allowed visualization of real-time mucosal changes, such as the improvement of ulcers and bleeding, and newly emerged lymphangiectasia, without causing the patient physical and mental stress. This information facilitated both subsequent evaluation of the clinical course and determination of the appropriate treatment strategy. In the second patient with chronic OGIB, a 10-year-old girl, the detection of severe ileal stenoses by capsule retention led to the diagnosis of non-specific multiple ulcers of the small intestine. After ileal resection, repeated CE detected the recurrence of multiple ulcers and enabled the optimal treatment strategy to be applied. CE confirmed small bowel involvement in a patient with unresponsive Crohn's disease (CD) and excluded CD in all five patients with suspected CD. Similarly, CE confirmed the absence of small bowel involvement in three of the four patients with recurrent abdominal pain, although one patient had nodular lymphoid hyperplasia. CONCLUSIONS Based on our results, CE is a valuable tool in the differential diagnoses of small bowel diseases, and repeated examination can provide real-time information that will enable evaluation of the clinical course in pediatric patients.

Abstract
Wireless capsule endoscopy is a simple, non-invasive technique for the visualization of the entire small bowel. It was introduced in clinical praxis in 2001 and has already become the method of choice for the investigation of small-bowel pathology. Capsule retention is a major complication, with an overall incidence of 1-2%, although reported rates vary widely from 0% to 21%, depending on the indication for the examination. This complication can occur at any level of the gastrointestinal tract and in most cases runs asymptomatically. However, symptomatic bowel obstruction requiring surgical or endoscopic removal of the impacted capsule can occur. Rarely, capsule retention can lead to intestinal perforation. Despite several years of experience with wireless capsule endoscopy, there is up to the present no safe means of predicting capsule retention. Radiological studies have a low diagnostic yield and tend to underestimate or overestimate small-bowel strictures. The role of the new generation patency capsule (Agile patency capsule) needs to be further documented. The experts agree that obtaining a careful history is perhaps the best single method to detect the possibility of retention.

Abstract
The advent of video capsule endoscopy (VCE) in 2000 has dramatically changed the diagnosis and management of many diseases of the small intestine. In this review we discuss the procedure, the various indications and contraindications, adverse effects, and future prospects of VCE. VCE has a significant role in the diagnosis of obscure gastrointestinal hemorrhage and Crohn's disease and has the highest diagnostic yield in comparison to other diagnostic modalities. Furthermore, VCE has gained an important role in the management and surveillance of suspected small bowel tumors and in patients with polyposis syndromes. Capsule enteroscopy may have a role in the work-up of symptomatic celiac disease and in the assessment of drug therapeutic efficacy and adverse small bowel effects. Although VCE is relatively non-invasive, it is contraindicated in patients with swallowing disorders, known or suspected gastrointestinal obstruction, strictures, or fistulas, and in patients with implanted electromedical devices. Other contraindications include pregnancy and children under 10. Capsule retention is the most feared complication of VCE with a frequency of 1%-2%. Risk factors and management of capsule retention are also discussed. It is probable that new indications for VCE will evolve and technological improvements will refine VCE's diagnostic accuracy and simplify video reviewing.

Abstract
BACKGROUND There is no consensus on the relative accuracy of capsule endoscopy (CE) versus double-balloon enteroscopy (DBE) to investigate obscure gastrointestinal bleeding (GIB). CE is less invasive, but DBE more directly examines the small bowel, and allows tissue sampling plus therapeutic intervention. OBJECTIVES To evaluate the yield and outcome of DBE following CE in patients with obscure GIB. METHODS After DBE became readily available at the Centre for Therapeutic Endoscopy and Endoscopic Oncology (St Michael's Hospital, Toronto, Ontario), all patients with obscure GIB seen from December 2002 to June 2007 were evaluated identically, first with CE, then with DBE (some with further interventions). Findings, adverse outcomes and interventions are reported. RESULTS Fifty-one patients (25 women) with a mean (range) age of 64.1 years (34 to 83 years) are reported. Eight patients underwent DBE twice, for a total of 59 DBEs. Fourteen patients had overt GIB and the median (range) number of red blood cell unit transfusions was 10 (0 to 100). The positive findings for each type of lesion were compared in these 51 patients: angiodysplasia (CE 64.7% and DBE 61%, P=0.3), ulcers (CE 19.6% and DBE 18.6%, P=0.5), bleeding lesions (CE 43.1% and DBE 15.3%, P=0.0004) and mass (CE 10.2% and DBE 8.5%, P=0.5). DBE provided the advantage of therapeutic intervention: argon plasma coagulation (33 of 59 DBEs), clipping (two of 59), both argon plasma coagulation and clipping (three of 59), polypectomy (two of 59), tattooing (52 of 59) and biopsies (11 of 59). DBE detected lesions not seen by CE in 21 patients; lesions were treated in 18 patients. However, CE detected 31 lesions not seen by DBE. No major complications occurred with either examination. CONCLUSION Overall detection rates for both techniques are similar. Each technique detected lesions not seen by the other. These data suggest that CE and DBE are complementary and that both evaluate obscure GIB more fully than either modality alone.

Abstract
Wireless capsule endoscopy is a new technique that allows complete exploration of the small bowel without external wires. Its role has been analyzed in many small bowel diseases such as obscure gastrointestinal bleeding, Crohn’s disease and gastrointestinal polyposis syndromes with promising results. Studies on other pathologies (i.e. small bowel tumour, celiac disease) are under evaluation to define the role of this technique.

Abstract
BACKGROUND AND AIM The presence of a critical intestinal stricture is a contraindication for conventional capsule endoscopy for the risk of impaction. Prior assessment of intestinal patency can substantially minimize this risk. The aim of the present study was to assess the safety and efficacy of the M2A patency capsule (PC) for verification of intestinal strictures. METHODS The M2A PC consists of a biodegradable body surrounding a small radiofrequency identification (RFID) tag. This capsule was administered to patients with known or suspected intestinal strictures. Patency was verified if the capsule was excreted intact. The capsule disintegrated into small fragments and only the RFID tag was excreted if retained at the stricture beyond a stipulated time. The patency scanner was used to detect the RFID tag externally. The M2A video capsule (VC) was administered to patients who excreted the intact capsule. RESULTS Twenty-six patients with known or suspected intestinal strictures were administered the M2A PC. This included 16 (61%) patients with tuberculosis, eight (31%) with Crohn's disease, and one each of postoperative and malignant strictures. Eight capsules were excreted intact within 72 h and two at 109 and 110 h. Fifteen capsules disintegrated in the G(I) tract and one capsule was removed during surgery. No PC-related complications were noted. Six of the eight patients who tested positive for patency were tested with the regular M2A VC with normal excretion. CONCLUSION The M2A PC is a reliable indicator of functional patency in suspected or even known cases of intestinal stricture. It could be used prior to conventional capsule endoscopy to predict and minimize the risk of impaction.

Abstract
The investigation of small bowel morphology is often mandatory in many patients with Crohn’s disease. Traditional radiological techniques (small bowel enteroclysis and small bowel follow-through) have long been the only suitable methods for this purpose. In recent years, several alternative imaging techniques have been proposed. To review the most recent advances in imaging studies of the small bowel, with particular reference to their possible application in Crohn’s disease, we conducted a complete review of the most important studies in which traditional and newer imaging methods were performed and compared in patients with Crohn’s disease. Several radiological and endoscopic techniques are now available for the study of the small bowel; each of them is characterized by a distinct profile of favourable and unfavourable features. In some cases, they may also be used as complementary rather than alternative techniques. In everyday practice, the choice of the technique to be used stands upon its availability and a careful evaluation of diagnostic accuracy, clinical usefulness, safety and cost. The recent development of innovative imaging techniques has opened a new and exciting area in the exploration of the small bowel in Crohn’s disease patients.

Abstract
Wireless capsule endoscopy (PillCam) represents a major advance in the study of small bowel disease since this procedure allows images of hitherto unreachable areas to be obtained. Approved for use by the Food and Drug Administration in August 2000, capsule endoscopy is currently a first line procedure in the study of small bowel disease. This technique consists of a non-reusable swallowable capsule (length 26 x 11 mm) that acquires video images while moving through the gastrointestinal tract propelled by natural peristalsis. The main indications of capsule endoscopy are evaluation of obscure gastrointestinal bleeding, chronic anemia, and inflammatory bowel disease. Contraindications are swallowing disorders and known or suspected small bowel strictures of any etiology. Consequently, small bowel follow through is useful prior to capsule endoscopy when these lesions are suspected.

Abstract
Capsule endoscopy is generally a safe procedure with few complications. Clinically significant complications including symptomatic capsule retention and aspiration occur in less than 2% of examinations. There is currently no accepted means of accurately predicting or preventing capsule retention. A modified capsule has recently been developed to determine patency in patients who have possible strictures. Incomplete small bowel examinations occur in 15% of examinations. After risk stratification, various pharmacologic and endoscopic adjuncts can be employed to minimize this complication. Technical complications occur most commonly early in a center's experience and decrease as experience with the device increases. Implanted cardiac devices are no longer an absolute contraindication to the examination but should be conducted after multidisciplinary consultation.

Abstract
BACKGROUND Capsule endoscopy has been found superior to barium x-rays and push enteroscopy in the investigation of obscure gastrointestinal bleeding and in the evaluation of suspected Crohn's disease. Currently, small bowel obstruction and strictures are considered by many physicians to be a contraindication to capsule endoscopy for fear of capsule retention or impaction. The goal of this study was to reassess this conventional wisdom that capsule endoscopy is contraindicated in small bowel obstruction and to determine the safety and efficacy of capsule endoscopy in the evaluation of patients with suspected stricture or small bowel obstruction. STUDY A retrospective chart review was performed using a database of 568 capsule endoscopy cases performed between August 2001 and November 2003. Cases of suspected small bowel obstruction were selected and reviewed. RESULTS Nineteen cases were identified in which capsule endoscopy was used in the setting of suspected small bowel obstruction. The diagnosis of suspected small bowel obstruction was based on symptoms alone in 8 cases and on symptoms plus abnormal radiographs in the remaining 11 cases. Capsule endoscopy made a definitive diagnosis in 5 of the 19 cases (26%): 2 Crohn's strictures, 1 radiation induced stricture, 1 nonsteroidal anti-inflammatory drug induced stricture, and 1 MALT lymphoma. The capsule was retained proximal to a stricture in 4 cases, in which the obstructing lesions were electively resected without complications. There was no case in which administration of the capsule led to an acute small bowel obstruction. CONCLUSIONS Capsule endoscopy can be safely used to help identify the etiology and site of a small bowel obstruction. Retention of the capsule may indicate the presence of a lesion requiring surgery, but small bowel obstruction or strictures are not in themselves contraindications to the procedure. It is understood, however, that retention may lead to surgery in a patient who otherwise may have been treated medically without surgery for the same illness (eg, Crohn's disease and nonsteroidal anti-inflammatory drug enteropathy).

Abstract
The European experience of wireless capsule endoscopy (WCE) inCrohn's disease (CD) is presented. Evidence from prospectivestudies comparing WCE with standard methods speaks in favor ofWCE as the method with the highest sensitivity for diagnosingsmall intestinal CD. WCE is likely to be helpful in diagnosing CD,in determining the extent of the disease, and in providing infor-mation on which of the current treatment approaches are specifi-cally effective within the small intestine. Although the invention ofthe patency capsule was helpful for diagnosing and characterizingsmall bowel strictures, the problem of capsule retention in CDpatients remains a controversial issue.
