Different roles of capsule endoscopy and double-balloon enteroscopy in obscure small intestinal diseases

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 differencein 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(χ 2 = 1.810,P = 0.179, Pearson χ 2 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(χ 2 = 22.146, P = 0.008, Kruskal Wallis Test). Small intestinal cancer(5/6 cases), vascular malformations(22/29 cases), and active bleeding(3/4cases) appeared more commonly in the patients over50 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.     

Capsule endoscopy in neoplastic diseases

Until recently, diagnosis and management of small-bowel tumors were delayed by the diffi culty of access to the small bowel and the poor diagnostic capabilities of the available diagnostic techniques. An array of new methods has recently been developed, increasing the possibility of detecting these tumors at an earlier stage. Capsule endoscopy （CE） appears to be an ideal tool to recognize the presence of neoplastic lesions along this organ, since it is non-invasive and enables the entire small bowel to be visualized. High- quality images of the small-bowel mucosa may be captured and small and ？ at lesions recognized, without exposure to radiation. Recent studies on a large population of patients undergoing CE have reported small-bowel tumor frequency only slightly above that reported in previous surgical series （range, 1.6%-2.4%） and have also confirmed that the main clinical indication to CE in patients with small-bowel tumors is obscure gastrointestinal （GI） bleeding. The majority of tumors identified by CE are malignant; many were unsuspected and not found by other methods. However, it remains difficult to identify pathology and tumor type based on the lesion’s endoscopic appearance. Despite its limitations, CE provides crucial information leading in most cases to changes in subsequent patient management. Whether the use of CE in combination with other new diagnostic （MRI or multidetector CT enterography） and therapeutic （Push- and-pull enteroscopy） techniques will lead to earlier diagnosis and treatment of these neoplasms, ultimately resulting in a survival advantage and in cost savings,remains to be determined through carefully-designed studies.     

Capsule endoscopy

Capsule endoscopy （CE） is a simple, safe, non-invasive, reliable technique, well accepted and tolerated by the patients, which allows complete exploration of the small intestine. The advent of CE in 2000 has dramatically changed the diagnosis and management of many diseases of the small intestine, such as obscure gastrointestinal bleeding, Crohn＇s disease, small bowel tumors, polyposis syndromes, etc. CE has become the gold standard for the diagnosis of most diseases of the small bowel. Lately this technique has also been used for esophageal and colonic diseases.     

胶囊内镜和CT仿真内镜诊断小肠疾病的对照研究

目的评价胶囊内镜和cT仿真内镜（CTVE）在小肠病变诊断方面的临床应用价值。方法回顾性总结3l例临床怀疑小肠疾病行胶囊内镜和CTVE检查患者的临床资料,参照最终诊断结果（手术病例以病理诊断为金标准,非手术病例依据后续检查及随访结果给出最终诊断）统计胶囊内镜、CTVE以及二者联合的诊断阳性率并行对比分析。结果最终诊断阳性26例,包括小肠肿瘤性病变16例、非肿瘤性病变10例,阴性5例。胶囊内镜诊断阳性24例,包括小肠肿瘤性病变14例（其中2例定位不准确,7例不能定性）和非肿瘤性病变10例;CTVE诊断阳性17例,包括小肠肿瘤性病变14例（其中1例定位不准确,4例不能定性）和非肿瘤性病变3例;胶囊内镜联合CTVE诊断阳性26例,包括小肠肿瘤性病变16例、非肿瘤性病变10例。对于小肠肿瘤性病变,胶囊内镜和CTVE诊断阳性率相同,均为87．5％（14／16）;而在总体诊断阳性率方面,胶囊内镜为77．4％（24／31）,CTVE为54．8％（17／31）,胶囊内镜联合CT仿真内镜为83．9％（26／31）,二者联合总体诊断阳性率明显高于CTVE（P=0．004）,但与胶囊内镜比较差异无统计学意义（P〉0．05）,胶囊内镜与CTVE比较差异也无统计学意义（P=0．065）。结论胶囊内镜和CTVE均有助于小肠疾病的诊断,胶囊内镜在诊断小肠非肿瘤性病变方面更有优势,而CTVE在判断小肠肿瘤性病变的位置和结构方面优于胶囊内镜,二者联合使用可进一步提高检出小肠疾病的能力。     

Capsule endoscopy in patients refusing conventional endoscopy

Capsule endoscopy is nowadays the diagnostic technique of choice in the study of small bowel pathologies, allowing the non-invasive study of the entire mucosa. This has led, together with new technical advances, to the creation of two new models (PillCam ESO and PillCam Colon) for the study of esophageal and colonic diseases. These two new capsules offer an interesting alternative to conventional endoscopy in the study of the upper and lower digestive tracts, because traditional endoscopy is often unpleasant and uncomfortable for the patient, can be painful, often requires moderate or deep sedation and is not without complications (hemorrhage, perforation, etc.). PillCam Colon is particularly important for its usefulness in the diagnosis of colonic polyps, and is a potentially useful tool in cases of incomplete colonoscopy or in colorectal cancer screening, even more when most patients are reluctant to undergo screening programs due to the said disadvantages of conventional colonoscopy. This article discusses the advantages of capsule endoscopy over conventional endoscopy, its current application possibilities and indications in routine clinical practice. In the various sections of the work, we assess the application of endoscopic capsule in different sections of the digestive tract (esophagus, stomach, and colon) and finally the potential role of panendoscopy with PillCam Colon.     

胶囊内镜与双气囊内镜诊断小肠疾病的比较

目的比较胶囊内镜和双气囊内镜对小肠疾病的检出率和诊断准确性，探讨其联合应用的临床意义。方法对116例不明原因消化道出血和102例不明原因腹痛或腹泻患者，共218例进行内镜检查。其中165例首选胶囊内镜，53例首选双气囊内镜。对胶囊内镜检查阴性或可疑病变者建议双气囊内镜检查，反之亦然。比较两种检查方法对小肠疾病的检出率、诊断率以及患者依从性、不良反应发生率等。结果1例胶囊内镜和2例双气囊内镜操作失败。51例患者行64次双气囊内镜检查，其中34例经口、4例经肛检查，13例分别接受经口和经肛检查。胶囊内镜对小肠病变的总检出率及对不明原因消化道出血的小肠疾病检出率（72．0％和88．0％），均明显高于双气囊内镜（41．2％和60．0％），诊断率也高于后者（51．8％和39．2％）。5例胶囊内镜检查阴性再经双气囊内镜检查者中，1例发现病灶；15例胶囊内镜检查怀疑小肠病变者中，12例经双气囊内镜结合活检病理确诊。而3例双气囊内镜未发现异常者再经胶囊内镜检查发现小肠病变。所有患者均未发生严重不良反应。结论胶囊内镜对小肠疾病检出率高，可作为怀疑小肠疾病，尤其是不明原因消化道出血的首选检查方法；双气囊内镜在胶囊内镜检查阴性者中仍可发现部分病灶，并能明确多数胶囊内镜下可疑病变，可作为胶囊内镜检查后的补充检测手段。     

胶囊内镜诊断小肠出血及与手术结果的对照研究

目的 通过胶囊内镜在诊断小肠出血中的应用探讨其诊断意义,并与手术结果进行对照研究。方法 利用胶囊内镜检查了50例小肠出血患者,所有患者均接受过胃镜、肠镜等传统检查方法未能明确诊断;将患者按照出血次数分为3组:A组出血大于5次,B组出血在2-5次之间,C组仅出血1次。有18例接受手术治疗。结果在50名患者中有39例(78％)患者发现了出血原因,A组患者中检出率为92.9％(26/28),B组为71.4％(10/14),C组为37.5％(3/8),经统计学处理,差异有显著性(P<0.01)。手术治疗患者中17例(94.4％)诊断与定位和胶囊内镜完全吻合。结论 胶囊内镜对小肠出血有较高的诊断价值,而且似乎在出血次数越多的患者中检出率越高。

Capsule endoscopy: The road ahead

Since its introduction into clinical practice 15 years ago, capsule endoscopy (CE) has become the first-line investigation procedure in some small bowel pathologies, and more recently, dedicated esophageal and colon CE have expanded the fields of application to include the upper and lower gastrointestinal disorders. During this time, CE has become increasingly popular among gastroenterologists, with more than 2 million capsule examinations performed worldwide, and nearly 3000 PubMed-listed studies on its different aspects published. This huge interest in CE may be explained by its non-invasive nature, patient comfort, safety, and access to anatomical regions unattainable via conventional endoscopy. However, CE has several limitations which impede its wider clinical applications, including the lack of therapeutic capabilities, inability to obtain biopsies and control its locomotion. Several research groups are currently working to overcome these limitations, while novel devices able to control capsule movement, obtain high quality images, insufflate the gut lumen, perform chromoendoscopy, biopsy of suspect lesions, or even deliver targeted drugs directly to specific sites are under development. Overlooking current limitations, especially as some of them have already been successfully surmounted, and based on the tremendous progress in technology, it is expected that, by the end of next 15 years, CE able to perform both diagnostic and therapeutic procedures will remain the major form of digestive endoscopy. This review summarizes the literature that prognosticates about the future developments of CE.     

Capsule endoscopy in pediatrics: A 10-years journey

Video capsule endoscopy(CE) for evaluation the esophagus(ECE), small bowel(SBCE) and the colon(CCE) is particularly useful in pediatrics, because this imaging modality does not require ionizing radiation, deep sedation or general anesthesia. The risk of capsule retention appears to be dependent on indication rather than age and parallels the adult experience by indication, making SBCE a relatively safe procedure with a significant diagnostic yield. The newest indication, assessment of mucosal change, greatly enhances and expands its potential benefit. The diagnostic role of CE extends beyond the SB. The use of ECE also may enhance our knowledge of esophageal disease and assist patient care. Colon CCE is a novel minimally invasive and painless endoscopic technique allowing exploration of the colon without need for sedation, rectal intubation and gas insufflation. The limited data on ECE and CCE in pediatrics does not yet allow the same conclusions regarding efficacy; however, both appear to provide safe methods to assess and monitor mucosal change in their respective areas with little discomfort. Moreover, although experience has been limited, the patency capsule may help lessen the potential of capsule retention; and newly researched protocols for bowel cleaning may further enhance CE’s diagnostic yield. However, further research is needed to optimize the use of the various CE procedures in pediatric populations.

Capsule endoscopy: role of bowel preparation in successful visualization

Background: Lesions of the small bowel that cannot be detected by other techniques can be indentified by capsule endoscopy. Good preparation before any endoscopic procedure is the most important factor for patient safety, quality of care and cost effectiveness. This should also apply to capsule endoscopy. The aim of this study was to evaluate the quality and efficacy of preparation with oral sodium phosphate for capsule endoscopy. Methods: A retrospective cohort study design was used. The study sample consisted of 32 consecutive patients scheduled for capsule endoscopy in two periods; the first 10 patients were prepared with overnight fasting only, and the next 22 with oral sodium phosphate. An experienced endoscopist and gastroenterology nurse, who were blinded to the method used, graded the quality of preparation. Results: Small‐bowel cleansing was significantly better in patients given sodium phosphate. Five patients (50%) received a poor preparation rating in the first period compared with only 1 (4.5%) of the 22 patients given oral sodium phosphate (P?=?0.01). Intraluminal fluid was noted in 9 patients (90%) in the first group after a mean of 53?±?60?min, and in 17 patients (77%) in the second group after a mean of 158?±?71?min (P?Conclusions: Bowel preparation with sodium phosphate before capsule endoscopy offers better visualization than overnight fasting alone and induces fewer disturbances by intraluminal turbid fluid.

胶囊内镜与双气囊小肠镜对小肠疾病诊断的荟萃分析

目的比较胶囊内镜和双气囊小肠镜对小肠疾病的阳性检出率。方法从Medline、Embase、Elsevier Science Direct和中国期刊全文数据库中检索比较胶囊内镜和双气囊小肠镜对小肠疾病阳性检出率的前瞻性研究。对各项研究中2种内镜的阳性检出率比数比（OR）行荟萃分析，经异质性检验后采用固定效应模型或随机效应模型进行统计分析。并根据可能产生异质性的原因进行分层分析。结果共有8项研究入选（n=277）。荟萃结果表明，胶囊内镜和双气囊小肠镜对小肠疾病阳性检出率没有显著差别[170／277比156／277，随机效应模式：OR为1．21（95％可信区间CI：0．64，2．29）]。分层分析提示：胶囊内镜的阳性率显著高于未采用经口和经肛这2种进镜方式相结合的双气囊小肠镜[137／219比110／219，固定效应模式：OR为1．67（95％CI：1．14，2．44），（P〈0．01）]；而低于用这2种进镜方式相结合的双气囊小肠镜检查，但差异没有统计学意义[26／48比37／48，随机效应模式：OR0．33（95％CI：0．05，2．21），（P〉0．05）]。进一步对5项全文发表的关于对不明原因消化道出血诊断的研究进行荟萃，结果仍然提示胶囊内镜的阳性检出率明显高于未采用经口和经肛这2种进镜方式相结合的双气囊小肠镜[118／191比96／191，固定效应模式：OR1．61（95％CI：1．07，2．43），（P〈0．05）]，但显著低于2种进镜方式相结合的双气囊小肠镜检查[11／24比21／24，固定效应模式：OR0．12（95％CI：0．03，0．52），（P〈0．01）]。结论双气囊小肠镜经口和经肛2种进镜方式联合应用的阳性率可能高于胶囊内镜，对这2种内镜的选择，应该取决于病人的一般状况及其意愿，医疗单位所具备的能力，以及病灶是否可能需要采取进一步的介入治疗。     

Capsule endoscopy findings in patients with suspected Crohn''s disease and biochemical markers of inflammation

BACKGROUND: Because it provides a direct view of superficial lesions in the small bowel, capsule endoscopy is a promising diagnostic tool for studying patients with suspected Crohn's disease undetected by conventional modalities. AIM: To assess the role of capsule endoscopy in the diagnosis of patients with suspected Crohn's disease. PATIENTS AND METHODS: Thirty-eight patients (16 males, mean age 46.2 years) with suspected Crohn's disease but negative at conventional imaging were examined using capsule endoscopy. They were divided into 2 groups: 12 patients with ongoing symptoms (Group 1), and 26 with ongoing symptoms and biochemical markers of inflammation (Group 2). Capsule endoscopy findings were classified as diagnostic (multiple erosions/ulcerations), suspicious (相似文献   

Capsule endoscopy in celiac disease

Video capsule endoscopy is an attractive and patient- friendly tool that provides high quality images of the small bowel. Obscure gastrointestinal bleeding is the primary and most evaluated indication to capsule endoscopy; however, indications are expanding and a small number of preliminary reports have been presented concerning the role of video capsule endoscopy in the diagnosis of celiac disease. The purpose of this review is to update the current knowledge and to hypothesize on future perspectives of the use of video capsule endoscopy in patients with celiac disease.     

Diagnosis of Ascaris lumbricoides infection using capsule endoscopy

Ascaris lumbricoides (A. lumbricoides ) is the most common intestinal roundworm parasite, infecting approximately one quarter of the world’s population. Infection can lead to various complications because it can spread along the gastrointestinal tract. Although A. lumbricoides infection is a serious healthcare issue in developing countries, it now also has a worldwide distribution as a result of increased immigration and travel. Intestinal obstruction is the most common complication of A. lumbricoides infection, potentially leading to even more serious consequences such as small bowel perforation and peritonitis. Diagnosis is based primarily on stool samples and the patient’s history. Early diagnosis, aided in part by knowledge of the local prevalence, can result in early treatment, thereby preventing surgical complications associated with intestinal obstruction. Further, delay in diagnosis may have fatal consequences. Capsule endoscopy can serve as a crucial, non-invasive diagnostic toolfor A. lumbricoides infection, especially when other diagnostic methods have failed to detect the parasite. We report a case of A. lumbricoides infection that resulted in intestinal obstruction at the level of the ileum. Both stool sample examination and open surgery failed to indicate the presence of A. lumbricoides, and the cause of the obstruction was only revealed by capsule endoscopy. The patient was treated with anthelmintics.
