[PMID: 38254753 PMCID: PMC10813471 DOI: 10.3390/cancers16020262] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 12/21/2023] [Accepted: 12/30/2023] [Indexed: 01/24/2024] Open
Abstract
Small bowel tumors (SBT) are relatively rare, but have had a steadily increasing incidence in the last few decades. Small bowel capsule endoscopy (SBCE) and device-assisted enteroscopy are the main endoscopic techniques for the study of the small bowel, the latter additionally providing sampling and therapeutic options, and hence acting complementary to SBCE in the diagnostic work-up. Although a single diagnostic modality is often insufficient in the setting of SBTs, SBCE is a fundamental tool to drive further management towards a definitive diagnosis. The aim of this paper is to provide a concise narrative review of the role of SBCE in the diagnosis and management of SBTs.

Abstract
Both computed tomography enterography (CTE) and video capsule endoscopy (VCE) are used in identifying small intestinal pathology in patients with suspected small bowel bleeding (SSBB) following normal upper gastrointestinal endoscopy and colonoscopy. Evidence of the comparative accuracy of these two modalities is crucial for clinical and healthcare decision-making. Comprehensive electronic searches were performed for studies on CTE and/or VCE with reference standard(s). Study selection, data extraction and quality assessment were completed by two authors independently. The QUADAS-2 and QUADAS-C tools were used to assess risk of bias, and applicability. Meta-analysis was performed using a bivariate model to obtain summary estimates of sensitivity, specificity, positive and negative likelihood ratios. Twenty-five studies involving 1986 patients with SSBB were included. Four of these were head-to-head comparison of CTE and VCE. Overall, VCE provided significantly higher sensitivity of 0.74 (95% CI: 0.61-0.83) versus 0.47 (95% CI: 0.32-0.62) for CTE, while CTE showed significantly higher specificity of 0.94 (95% CI: 0.64-0.99) versus 0.53 (95% CI: .36-0.69) for VCE. The positive likelihood ratio of CTE was 7.36 (95% CI: 0.97-56.01) versus 1.58 (95% CI: 1.15-2.15) for VCE and the negative likelihood ratio was 0.49 (95% CI: 0.33-0.72) for VCE versus 0.56 (0.40-0.79) for CTE. A secondary analysis of only head-to-head comparative studies gave results that were similar to the main analysis. Certainty of evidence was moderate. Neither VCE nor CTE is a perfect test for identifying etiology of SSBB in small intestine. VCE was more sensitive while CTE was more specific. Clinicians should choose the appropriate modality depending on whether better sensitivity or specificity is required in each clinical scenario.

Abstract
Small-bowel tumors represent a rare entity comprising 0.6% of all new cancer cases in the US, and only 3% of all gastrointestinal neoplasms. They are a heterogenous group of neoplasms comprising of about forty different histological subtypes with the most common being adenocarcinoma, neuroendocrine tumors, stromal tumors and lymphomas. Their incidence has been reportedly increasing over recent years, partly owing to the advances and developments in the diagnostic modalities. Small-bowel capsule endoscopy, device assisted enteroscopy and dedicated small-bowel cross-sectional imaging are complimentary tools, supplementing each other in the diagnostic process. Therapeutic management of small-bowel tumors largely depends on the histological type and staging at diagnosis. The aim of the present review article is to discuss relevant advances in the diagnosis and management of small-bowel tumors.

Abstract
MR1: ESGE recommends small-bowel capsule endoscopy as the first-line examination, before consideration of other endoscopic and radiological diagnostic tests for suspected small-bowel bleeding, given the excellent safety profile of capsule endoscopy, its patient tolerability, and its potential to visualize the entire small-bowel mucosa.Strong recommendation, moderate quality evidence. MR2: ESGE recommends small-bowel capsule endoscopy in patients with overt suspected small-bowel bleeding as soon as possible after the bleeding episode, ideally within 48 hours, to maximize the diagnostic and subsequent therapeutic yield.Strong recommendation, high quality evidence. MR3: ESGE does not recommend routine second-look endoscopy prior to small-bowel capsule endoscopy in patients with suspected small-bowel bleeding or iron-deficiency anemia.Strong recommendation, low quality evidence. MR4: ESGE recommends conservative management in those patients with suspected small-bowel bleeding and high quality negative small-bowel capsule endoscopy.Strong recommendation, moderate quality evidence. MR5: ESGE recommends device-assisted enteroscopy to confirm and possibly treat lesions identified by small-bowel capsule endoscopy.Strong recommendation, high quality evidence. MR6: ESGE recommends the performance of small-bowel capsule endoscopy as a first-line examination in patients with iron-deficiency anemia when small bowel evaluation is indicated.Strong recommendation, high quality evidence. MR7: ESGE recommends small-bowel capsule endoscopy in patients with suspected Crohn's disease and negative ileocolonoscopy findings as the initial diagnostic modality for investigating the small bowel, in the absence of obstructive symptoms or known bowel stenosis.Strong recommendation, high quality evidence. MR8: ESGE recommends, in patients with unremarkable or nondiagnostic findings from dedicated small-bowel cross-sectional imaging, small-bowel capsule endoscopy as a subsequent investigation if deemed likely to influence patient management.Strong recommendation, low quality evidence. MR9: ESGE recommends, in patients with established Crohn's disease, the use of a patency capsule before small-bowel capsule endoscopy to decrease the capsule retention rate.Strong recommendation, moderate quality evidence. MR10: ESGE recommends device-assisted enteroscopy (DAE) as an alternative to surgery for foreign bodies retained in the small bowel requiring retrieval in patients without acute intestinal obstruction.Strong recommendation, moderate quality evidence. MR11: ESGE recommends DAE-endoscopic retrograde cholangiopancreatography (DAE-ERCP) as a first-line endoscopic approach to treat pancreaticobiliary diseases in patients with surgically altered anatomy (except for Billroth II patients).Strong recommendation, moderate quality evidence.

Abstract
In potential small bowel bleeding, video capsule endoscopy (VCE) is excellent to detect mucosal lesions, while mural-based lesions are better detected by computed tomography enterography (CTE). A predictive tool to identify mural-based lesions should guide selecting investigations. In this retrospective study, we developed and validated the "MURAL" model based on logistic regression to predicts bleeding from mural-based lesions. Cost-effectiveness analysis comparing diagnostic strategy among VCE, CTE, and MURAL model was performed. Of 296 patients, 196 and 100 patients were randomly included in the derivative and validation cohorts, respectively. The MURAL model comprises 5 parameters: age, presence of atherosclerosis, chronic kidney disease, antiplatelet use, and serum albumin level. The area under the receiver operating characteristic curve was 0.778 and 0.821 for the derivative and validation cohorts, respectively. At a cutoff value of 24.2%, the model identified mural-based lesions with 70% sensitivity and 83% specificity in the validation cohort. Cost-effectiveness analysis revealed that application of the MURAL model demonstrated a comparable missed lesion rate but had a lower missed tumor rate, and lower cost compared to VCE strategy. The model for predicting mural-based lesions provide some guidance in investigative decision-making, which may improve diagnostic efficiency and reduce costs.

Abstract
BACKGROUND Patients with potential small bowel bleeding (PSBB) who have negative results of video capsule endoscopy (VCE), clinical course, rate of rebleeding, and missed lesions with their predictors are essential for further management decision. METHODS This retrospective study included patients presenting with PSBB who had negative VCE findings between January 2008 and December 2016. All patients had to have at least two years of follow-up data to be included. Patients with <2 years of follow-up in their medical record were interviewed by telephone to determine if any unrecorded rebleeding episodes occurred. RESULTS One hundred forty-two patients were included. The mean age was 60.9 years, and 52.8% were male. Eighty-one patients presented with overt bleeding. The median duration of follow-up was 5.08 years. During the follow-up period, 30 patients experienced rebleeding. The cumulative rate of rebleeding at 1, 2, and 5 years was 10.0%, 14.3%, and 22.4%, respectively. Multivariate analysis showed nonsteroidal anti-inflammatory drugs (NSAIDs) and presentation of overt bleeding to be independent predictors of rebleeding. There were only nine small bowel lesions (6.3%) missed by VCE. These nine patients, compared with others, were significantly younger and tended to present with overt bleeding. CONCLUSION Rebleeding was not uncommon in PSBB after negative VCE; however, the rate of missing small bowel lesions was low. Nonetheless, further investigations may be considered in young patients who present with overt bleeding.

Abstract
BACKGROUND One of the aims of the European Society of Gastrointestinal Endoscopy (ESGE) is to encourage high quality endoscopic research at a European level. In 2016, the ESGE research committee published a set of research priorities. As endoscopic research is flourishing, we aimed to review the literature and determine whether endoscopic research over the last 4 years had managed to address any of our previously published priorities. METHODS As the previously published priorities were grouped under seven different domains, a working party with at least two European experts was created for each domain to review all the priorities under that domain. A structured review form was developed to standardize the review process. The group conducted an extensive literature search relevant to each of the priorities and then graded the priorities into three categories: (1) no longer a priority (well-designed trial, incorporated in national/international guidelines or adopted in routine clinical practice); (2) remains a priority (i. e. the above criterion was not met); (3) redefine the existing priority (i. e. the priority was too vague with the research question not clearly defined). RESULTS The previous ESGE research priorities document published in 2016 had 26 research priorities under seven domains. Our review of these priorities has resulted in seven priorities being removed from the list, one priority being partially removed, another seven being redefined to make them more precise, with eleven priorities remaining unchanged. This is a reflection of a rapid surge in endoscopic research, resulting in 27 % of research questions having already been answered and another 27 % requiring redefinition. CONCLUSIONS Our extensive review process has led to the removal of seven research priorities from the previous (2016) list, leaving 19 research priorities that have been redefined to make them more precise and relevant for researchers and funding bodies to target.

Abstract
Video capsule endoscopy and device-assisted enteroscopy are complementary technologies. Capsule endoscopy is a highly acceptable technology with high diagnostic yield that can guide a subsequent enteroscopy approach. This article aims to focus on the role of video capsule endoscopy as a prelude to deep enteroscopy with a focus on the strengths and limitations of either approach.

Causes and Clinical Characteristics of Small Bowel Bleeding in Northern Vietnam. Can J Gastroenterol Hepatol 2020; 2020:8884092. [PMID: 33313021 PMCID: PMC7721493 DOI: 10.1155/2020/8884092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 11/13/2020] [Accepted: 11/23/2020] [Indexed: 11/17/2022] Open
Abstract
AIM Causes, clinical features, and diagnostic approaches for small bowel (SB) bleeding were analyzed to derive recommendations in dealing with this clinical condition. METHODS We included 54 patients undergoing surgical treatment for SB bleeding, from January 2009 to December 2019. Detailed clinical data, diagnosis procedures, and causes of bleeding were collected. RESULTS Among 54 cases with SB bleeding, the most common causes were tumors (64.8%), followed by angiopathy (14.8%), ulcers (9.3%), diverticula (5.6%), tuberculosis (3.7%), and enteritis (1.9%). Most tumors (32/35 cases, 91.4%) and vascular lesions (8/8 cases, 100%) were located in the jejunum. The incidence of tumors was higher in the older (30/41 cases, 73.1%) than that in patients younger than 40 years of age (5/13 cases, 38.5%, P < 0.01). Common initial findings were melena (68.5%) and hematochezia (31.5%). The overall diagnostic yield of computed tomographic enterography (CTE) was 57.4% (31/54 cases), with the figures for tumors, vascular lesions, and inflammatory lesions being 71.4% (25/35 cases), 62.5% (5/8 cases), and 12.5% (1/8 cases), respectively. Double-balloon enteroscopy (DBE) definitively identified SB bleeding sources in 16/22 (72.7%) patients. CONCLUSION Tumors, angiopathy, ulcers, and diverticula were the most common causes of SB bleeding in Northern Vietnamese population. CTE has a high detection rate for tumors in patients with SB bleeding. CTE as a triage tool may identify patients before double-balloon enteroscopy because of the high prevalence of SB tumors.

Abstract
Video capsule endoscopy became a reality in 2001. This device enabled us to directly view the mucosa of the small intestine for the first time. The main indications for the video capsule remain the detection of small intestinal bleeding and iron deficiency anemia, diagnosis and management of Crohn's disease, and detection of tumors. The device is extraordinarily safe and can be used in the very young to the very old. However, there remain several areas of controversy and difficulty. These are covered in this article and include details of indications and contraindications, whether to prepare patients, whether or not to use simethicone and prokinetics. Detection of location of the capsule remains a major engineering challenge. Reading the videos reliably and quickly remains challenging. However, artificial intelligence and machine learning are already on the horizon to provide assistance. New uses for capsule endoscopy promise more accurate diagnosis and hence improved management of acute gastrointestinal bleeding. The colon capsule may eventually help those who refuse conventional colonoscopy, and robotically controlled capsules may be helpful in screening for serious disease in patients with upper abdominal complaints. The advent of the broadening use of video capsule endoscopy is, though it will be controversial, embraced by some and derided by others; such is the nature of technological development. In the long run, if the use of the video capsule, based on sound evidence-based studies, can be shown to improve the care of our patients and reduce the cost of health care, its use will continue to expand.

Obscure gastrointestinal bleeding localization using preoperative super-selective mesenteric angiography and intraoperative methylene blue injection: A case report and literature review. Int J Surg Case Rep 2019; 65:69-72. [PMID: 31689632 PMCID: PMC6838790 DOI: 10.1016/j.ijscr.2019.10.059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 10/24/2019] [Accepted: 10/24/2019] [Indexed: 11/30/2022] Open
Abstract
INTRODUCTION Currently available diagnostic tests for localizing the source of gastrointestinal bleeding include esophagogastroduodenoscopy, colonoscopy, push enteroscopy, video capsule endoscopy, deep enteroscopy, nuclear scan, angiography, radiographic contrast studies of the small bowel, intraoperative enteroscopy, and computed tomography scanning. Despite these diagnostic modalities obscure gastrointestinal bleeding (OGIB) can be difficult to localize, making surgical intervention challenging. PRESENTATION OF CASE We report the case of a 78-year-old patient who presented with OGIB, melena and passing bright red blood per rectum, with a hemoglobin of 4.8 g/dl requiring multiple blood transfusions. Initially the source of the bleeding was difficult to identify. Eventually, a preoperative superior mesenteric angiogram was performed, identifying an arteriovenous malformation (AVM) within the small bowel as the source of OGIB. Intraoperative methylene blue was then injected through the previously placed angiogram catheter to further localize the bowel segment with the lesion. DISCUSSION Despite multiple diagnostic modalities, OGIB, especially originating in the small bowel, is challenging to localize, making surgical intervention difficult. Methylene blue is frequently used intraoperatively to properly identify anatomic landmarks. CONCLUSION In cases of OGIB, superselective mesenteric angiography (SSMA) with intraoperative methylene blue injection can be used as an adjunct to routine diagnostic modalities to guide surgical interventions for controlling hemorrhage and for limiting the extent of bowel resection.

Abstract
OBJECTIVE The aim of this study was to evaluate the computed tomography enterography (CTE) characteristics of bleeding Meckel diverticulum. METHODS The CTE images of 35 patients with Meckel diverticulum and gastrointestinal bleeding were retrospectively evaluated. RESULTS Meckel diverticulum was visualized in 33 of 35 patients and located in the right lower abdomen (20/33), midline lower abdomen (8/33), left lower abdomen (3/33), or paramedially near the umbilicus (2/33). The Meckel diverticulum was visualized on the antimesenteric side of the ileum in 16 patients (48.5%) and pointed toward the umbilicus in 10 (30.3%). The diverticulum appeared as a blind-ended tubular (22/33 [66.7%]) or saccular (11/33 [33.3%]) bowel segment. Separated supplying vessel was identified in 15 patients (45.5%) and associated with diverticulum (P = 0.037). The ectopic tissue was pathologically confirmed in 11 (33.3%) of 33 patients and was associated with diverticular nodules (P = 0.002). CONCLUSIONS Awareness of CTE features could aid in the preoperative assessment of bleeding Meckel diverticulum.

Abstract
PURPOSE OF REVIEW The objective is to provide an overview on the cause of small bowel bleeding. We discuss the role of small bowel endoscopy in the management of small bowel bleeding and provide an outline of pharmacotherapy that can be additionally beneficial. RECENT FINDINGS Small bowel capsule endoscopy (SBCE) is the initial diagnostic investigation of choice in small bowel bleeding. Computed tomography (CT) can be helpful in the context of small bowel tumours. Device-assisted enteroscopy (DAE) enables several therapeutic procedures such as argon plasma coagulation (APC) and haemoclip application. It can also guide further management with histology or by marking culprit lesions with India ink. A persistent rate of rebleeding despite APC is increasingly being reported. Pharmacotherapy has an emerging role in the management of small bowel bleeding. Somatostatin analogues are a well tolerated class of drugs that can play an additional role in the management of refractory bleeding secondary to small bowel angioectasias. SUMMARY SBCE is useful in determining the cause of small bowel bleeding. DAE offers an endoscopic therapeutic approach to small bowel bleeding replacing surgery and intraoperative enteroscopy. Pharmacotherapy, in addition to endotherapy, can play an important role in the management of multifocal, recurring bleeding small bowel lesions.

Accuracy of Computed Tomographic Enterography for Obscure Gastrointestinal Bleeding: A Diagnostic Meta-analysis. Acad Radiol 2018; 25:196-201. [PMID: 29122470 DOI: 10.1016/j.acra.2017.09.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2017] [Revised: 08/31/2017] [Accepted: 09/02/2017] [Indexed: 12/22/2022]
Abstract
RATIONALE AND OBJECTIVES Obscure gastrointestinal bleeding (OGIB) is the bleeding from the gastrointestinal tract without definite source that persists and recurs after a negative endoscopic evaluation. The study aimed to systematically evaluate the diagnostic accuracy of computed tomography enterography on OGIB detection by meta-analysis. MATERIALS AND METHODS Studies were searched in relevant databases. With predefined inclusion criteria, eligible studies were included, followed by quality assessment using the Quality Assessment of Diagnostic Accuracy Studies scoring system. The Meta-DiSc software was used to implement the meta-analysis, and sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio with their 95% confidence intervals (CIs) were used as the effect size. Publication bias was determined by Egger test. RESULTS A set of nine studies was included in this meta-analysis, having a relatively high quality. Under the random effects model, the pooled sensitivity and specificity were 0.724 (95% CI: 0.651-0.789) and 0.752 (95% CI: 0.691-0.807), respectively. Under the fixed effects model, the pooled positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were 2.949 (95% CI: 2.259-3.850), 0.393 (95% CI: 0.310-0.497), and 9.452 (95% CI: 5.693-15.692), respectively. The area under curve of the summary receiver operating characteristic curve was 0.7916 (95% CI: 0.723-0.860). No obvious publication bias was detected (t = 1.62, P = .181). CONCLUSIONS Computed tomography enterography might be used as a complementary to video capsule endoscopy instead of an alternative for the detection of OGIB.

Abstract
Background In recent years major advances have been made in the management of patients with acute lower gastrointestinal bleeding. The aim of this study was to investigate the characteristics and clinical outcome of patients with acute lower gastrointestinal bleeding (ALGIB) treated with an intensive protocol. Methods We analyzed the medical records of 528 patients with ALGIB. All patients after hemodynamic stabilization underwent colonoscopy during the first 24 h of hospitalization and capsule enteroscopy when needed. Patients with massive ongoing bleeding underwent computed tomography angiography (CTA), and when active bleeding was detected embolization was immediately performed. Results The mean age of the patients was 70.2 ± 14.6 years and 271 (51.3%) of them were men. At least one comorbidity was present in 464 patients (87.9%), cardiovascular disease in 266 (50.4%), while 158 (30%) patients were on antiplatelet drugs and 96 (18.2%) on anticoagulants. The most common causes of bleeding were diverticulosis (19.7%) and ischemic colitis (19.3%). Thirty-six patients (6.9%) had small intestinal bleeding. In 117 patients (22.2%) active bleeding or recent bleeding stigmata were found and in 82 of them (92.1%) endoscopic hemostasis was applied. Embolization was performed in 10 (1.9%) and was successful in seven (70%) cases, while surgical hemostasis was required in only six (1.1%) cases. Forty-four (8.3%) patients had a rebleeding episode, and 13 patients died with an overall mortality of 2.5%. Conclusions Management of ALGIB based on an intensive protocol is safe and effective. The bleeding source can be identified in most cases with a favorable outcome.

Abstract
OBJECTIVE Meckel diverticulum may become symptomatic if it is complicated by hemorrhage, intestinal obstruction, diverticulitis, or tumor. Although classically described in children, it is often missed in adults because of lack of suspicion and difficulty in detection. The purpose of this article is to review the imaging findings and management of Meckel diverticulum and its complications. CONCLUSION Although it is infrequently encountered incidentally, Meckel diverticulum should be considered especially when interpreting examinations for abdominal pain, small-bowel obstruction, and gastrointestinal bleeding.
