Diagnosis of obscure Gastrointestinal Bleeding: Capsule Endoscopy or Double Balloon Enteroscopy?

引用

Open Journal of Gastroenterology 2018年第3期8卷 79-85页

作者： Gaudel Saroj Prasad Qian Yu Chibin Pu Shrestha Sachin Mulmi Department of Gastroenterology Zhongda Hospital Affiliated to Southeast University Nanjing China

The development of capsule endoscopy (CE) and double balloon enteroscopy (DBE) has significantly enhanced the visualization of the small bowel. CE and DBE have proven to be the choice of investigation for the diagnosis of small bowel disease and is an evident indication for obscure gastrointestinal bleeding (OGIB). CE or DBE respectively are frequent option of professionals for the diagnosis of obscure gastrointestinal bleeding. The purpose of this review is to provide an overview of studies focused on patients with obscure gastrointestinal bleeding with previous CE and/or DBE intervention. Studies show that CE and DBE have similar diagnostic yields for obscure gastrointestinal bleeding. Although with few chances for false negative results, most researches showed good concordance between CE and DBE. However due to its non-invasiveness, safety, patient tolerability and ability to view the entire small bowel, CE can be recommended as a first choice of investigation. DBE, despite being more invasive, is a necessary second choice, which has both diagnostic and therapeutic value, although skilled endoscopist and sedation are required and complications like bleeding, perforation, pancreatitis etc. may occur.

AIM: To elucidate the association between small bowel diseases(SBDs) and positive fecal occult blood test(FOBT) in patients with obscure gastrointestinal bleeding(OGIB).METHODS: Between February 2008 and August 2013, 202 patients with OGIB who performed both capsule endoscopy(CE) and FOBT were enrolled(mean age; 63.6 ± 14.0 years, 118 males, 96 previous overt bleeding, 106 with occult bleeding). All patients underwent immunochemical FOBTs twice prior to CE. Three experienced endoscopists independently reviewed CE videos. All reviews and consensus meeting were conducted without any information on FOBT results. The prevalence of SBDs was compared between patients with positive and negative ***: CE revealed SBDs in 72 patients(36%). FOBT was positive in 100 patients(50%) and negative in 102(50%). The prevalence of SBDs was significantly higher in patients with positive FOBT than those with negative FOBT(46% vs 25%, P = 0.002). In particular, among patients with occult OGIB, the prevalence of SBDs was higher in positive FOBT group than negative FOBT group(45% vs 18%, P = 0.002). On the other hand, among patients with previous overt OGIB, there was no significant difference in the prevalence of SBDs between positive and negative FOBT group(47% vs 33%, P = 0.18). In disease specific analysis among patients with occult OGIB, the prevalence of ulcer and tumor were higher in positive FOBT group than negative FOBT group. In multivariate analysis, only positive FOBT was a predictive factors of SBDs in patients with OGIB(OR = 2.5, 95%CI: 1.4-4.6, P = 0.003). Furthermore, the trend was evidentam on g patients with occult OGIB who underwent FOBT on the same day or a day before CE. The prevalence of SBDs in positive vs negative FOBT group were 54% vs 13% in patients with occult OGIB who underwent FOBT on the same day or the day before CE(P = 0.001), while there was no significant difference between positive and negative FOBT group in those who underwent FOBT two or more d

AIM: To assess the rate of recurrent bleeding of the small bowel in patients with obscure bleeding already undergone capsule endoscopy (CE) with negative results. METHODS: We reviewed the medical records related to 696 consecutive CE performed from December 2002 to January 2011, focusing our attention on patients with recurrence of obscure bleeding and negative CE. Evaluating the patient follow-up, we analyzed the recurrence rate of obscure bleeding in patient with a negative CE. Actuarial rates of rebleeding during follow-up were calculated, and factors associated with rebleeding were assessed through an univariate and multivariate analysis. A P value of less than 0.05 was regarded as statistically significant. The sensitivity, specificity, and positive and negative predictive values (PPV and NPV) of negative CE were calculated. RESULTS: Two hundred and seven out of 696 (29.7%) CE studies resulted negative in patient with obscure/overt gastrointestinal bleeding. Overall, 489 CE (70.2%) were positive studies. The median follow-up was 24 mo (range 12-36 mo). During follow-up, recurrence of obscure bleeding was observed only in 34 out of 207 negative CE patients (16.4%); 26 out of 34 with obscure overt bleeding and 8 out of 34 with obscure occult bleeding. The younger age (obscure gastrointestinal bleeding and negative CE had a significantly lower rebleeding rate, and further invasive investigations can be deferred.

AIM: To compare the roles of capsule endoscopy(CE)and double-balloon enteroscopy(DBE) in the diagnosis of obscure small bowel ***: 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 ***: 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 hemangi

Evaluation and outcomes of patients with obscure gastrointestinal bleeding

World Journal of Gastrointestinal Pathophysiology 2014年第4期5卷 479-486页

作者： Cositha Santhakumar Ken Liu Department of Gastroenterology and Hepatology Level 1 West Concord Repatriation General Hospital

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.

Small bowel Dieulafoy lesions: An uncommon cause of obscure bleeding in cirrhosis

引用

World Journal of Gastrointestinal Endoscopy 2016年第16期8卷 568-571页

作者： Grainne Holleran Mary Hussey Deirdre Mc Namara Trinity Academic Gastroenterology Group Trinity College DublinTrinity Centre for Health SciencesTallaght Hospital

Dieulafoy lesions(DLs) are an uncommon cause of gastrointestinal bleeding, accounting for up to 2% of cases overall. They are largely under recognised and difficult to treat. Up to 95% occur in the stomach, and only case reports document their occurrence in the small bowel(SB). Little is known about their pathophysiology, although there have been associations made previously with chronic liver disease, thought to be due to the erosive effects of alcohol on the mucosa overlying the abnormally dilated vessels. We present a case series of 4 patients with a long duration of obscure gastrointestinal bleeding, who were diagnosed with small intestinal DLs and incidentally diagnosed with chronic liver disease. The histories describe the challenges in both diagnosis and treatment of small intestinal DLs. Our case series suggest a previously unreported link between chronic liver disease and SB DLs which may be due to anatomical vasculature changes or a shift in angiogenic factors as a consequence of portal hypertension or liver cirrhosis.
