Abstract
PURPOSE OF REVIEW Crohn's disease (CD), requires accurate diagnosis and regular monitoring to manage disease activity, prevent complications, and improve outcomes. Intestinal ultrasound (IUS) has emerged as a noninvasive, real-time imaging modality, offering a valuable alternative to traditional diagnostic techniques such as magnetic resonance enterography (MRE), endoscopy and capsule endoscopy (CE). This review examines recent advances in IUS for the diagnosis and monitoring of small bowel CD, with a focus on its applications, benefits, and limitations. RECENT FINDINGS Recent studies have demonstrated that IUS provides high sensitivity and specificity in detecting key markers of disease activity, including bowel wall thickness (BWT), bowel wall flow (BWF), and bowel wall stratification (BWS). Advances in IUS techniques, such as elastography and contrast-enhanced ultrasound (CEUS), have expanded its diagnostic and prognostic capabilities, potentially enabling differentiation between inflammation and fibrosis. However, challenges remain, including operator dependency, variability in scoring systems, and reduced sensitivity for superficial mucosal abnormalities. Efforts to standardize parameters and improve training have shown promise in addressing these limitations. SUMMARY IUS is a critical complementary tool for assessing disease activity, transmural healing, and postoperative recurrence in small bowel CD. Its noninvasiveness, cost-effectiveness, and real time assessment make it well suited for routine clinical use. Nonetheless, further multicentre studies are needed to validate scoring systems, optimize integration with other modalities, and improve consistency across clinical settings. IUS holds significant potential for advancing personalized care in small bowel CD, though ongoing research is required to refine its applications and maximize its clinical utility.

Abstract
In recent years, we have seen a considerable increase in the number of patients with inflammatory bowel diseases of unknown etiology, including both Crohn's disease and ulcerative colitis. Inflammatory bowel diseases can cause intestinal lesions throughout the gastrointestinal tract, necessitating gastrointestinal endoscopy for examining all relevant aspects, especially lesion characteristics, for differential diagnosis and histological diagnosis, to select the appropriate treatment options, determine treatment effectiveness, etc. Specific guidelines are necessary to ensure that endoscopy can be performed in a safe and more tailored and efficient manner, especially since gastrointestinal endoscopy, including enteroscopy, is a common procedure worldwide, including in Japan. Within this context, the Japan Gastroenterological Endoscopy Society has formulated the "Guidelines for the Endoscopic Diagnosis and Treatment of Inflammatory Bowel Diseases" to provide detailed guidelines regarding esophagogastroduodenoscopy, enteroscopy, and colonoscopy procedures for definitive diagnosis, as well as determination of treatment effectiveness in clinical cases of inflammatory bowel diseases.

Abstract
BACKGROUND Outcomes after ileocolonic resection in Crohn's disease [CD] are heterogeneous, and a clear definition of postoperative recurrence remains to be determined. Our Endpoints Working Group of the International Organization for the study of Inflammatory Bowel Disease [IOIBD] aimed to standardise postoperative outcomes, to discuss which endpoints should be used for postoperative clinical trials, and to define those which could be used in trials or registries. METHODS Based on a systematic review of the literature, recommendations and statements were drafted and sent to all IOIBD members for a first round of voting. Recommendations and statements were revised based on the voters' comments during a consensus hybrid conference open to all IOIBD members. If no agreement was reached after two rounds of voting, the statement was excluded. RESULTS In the systematic review, 3071 manuscripts were screened of which 434 were included. Sixteen recommendations were identified, of which 11 were endorsed. Recommendations and statements include that endoscopy remains the gold standard and should be used as a short-term primary endpoint in both observational cohorts and randomised controlled trials. Clinical symptoms classically used in clinical trials for luminal CD are not reliable in this specific situation. For that reason, longer-term endpoints should be based on the evidence of macroscopic inflammation assessed by imaging techniques, endoscopy, or as reflected by the presence of complications. CONCLUSIONS Agencies recommend the use of clinical evaluations, as in the case of luminal CD, and do not recognise primary endpoints based solely on endoscopy. This consensus has led to agreement on the need to define postoperative endoscopy-based and/or imaging-based endpoints.

Monitoring endoscopic postoperative recurrence in Crohn’s disease after an ileocecal resection. Does capsule endoscopy have a role in the short and long term? Acta Gastroenterol Belg 2022; 85:485-491. [DOI: 10.51821/85.3.10535] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/12/2022]
Abstract
Background: Small bowel capsule endoscopy (SBCE) is a noninvasive method to detect endoscopic postoperative recurrence (POR) after an ileocolonic resection in Crohn’s Disease (CD). Few studies have evaluated the role of SBCE in the early POR (= 12 months). Data for detection of late POR (>12 months) and evaluation of treatment response in previous POR is scarce. We aimed to assess the SBCE performance in the three scenarios (early-POR, late-POR, and previous-POR)
Methods: Retrospective 11-year cohort study of SBCE procedures performed on CD patients with ileocolonic resection. Disease activity by Rutgeerts score (RS), correlation with biomarkers, and therapeutic changes were recorded.
Results: We included 113 SBCE procedures (34 early-POR, 44 late-POR, and 35 previous-POR). 105 procedures (92.9%) were complete and 97 SBCE (85.5%) were conclusive with no differences between groups. Relevant POR (RS ≥i2) was more frequent in the early-POR group compared to late-POR (58.8% vs 27.3%, p=0.02). In the previous-POR, RS improved in 43.5% of procedures, worsened in 26%, and remained unchanged in 30.5%. Fecal calprotectin (FCP) value of 100µg/g displayed the best accuracy: sensitivity 53.8%, specificity 78.8%, positive predictive value 66.7% and negative predictive value 68.4%. SBCE guided therapeutic changes in 43 patients (38%). No adverse events occurred in our cohort.
Conclusion: SBCE is a safe and effective method to assess POR in the early and late setting in clinical practice, and for the evaluation of treatment response to previous POR. FCP is an accurate surrogate marker of POR and 100µg/g value had the best overall accuracy.

Abstract
Crohn’s disease (CD) is a chronic inflammatory disorder with a predilection for the small bowel. Although awareness of this disorder has increased over the years, it remains a diagnostic challenge for many physicians. This is exacerbated by the rising incidence and high recurrence rate following therapy in certain individuals. It is currently agreed that a multimodality approach is the best one, but with the advent of new modalities, that could be changing. Furthermore, given its impact on the mental health of patients and the cost of treatment, it is pertinent that we arrive at not only convenient but accurate modalities in its diagnosis and management. Among these investigative modalities is the relatively novel capsule endoscopy (CE) that not only provides a more patient-friendly alternative but avoids the need for invasiveness. Asides from its diagnostic capability, its influence on therapy and monitoring of known CD patients following treatment has been shown. This article has reviewed the current literature comparing the relevance of CE with other available modalities in diagnosing CD patients. We explored its therapeutic impact and how it influences monitoring post-treatment in CD. This article also discusses the complications of CE and the possible solutions to these complications in the future.

Abstract
Background Crohn’s disease (CD) recurrence can occur not only at the site of anastomosis but also elsewhere in the bowel following an ileocolic resection (ICR) procedure. The aims of the present study were to assess long-term outcomes of a primary ICR procedure for CD in consecutive patients and examine the location of the reoperation causative lesion. Methods We examined cases of surgery with ICR initially performed at our institution. Those with simultaneous multiple bowel resection or bowel resection with strictureplasty were excluded. Results A total of 169 patients who underwent ICR due to CD were enrolled. The median follow-up period was 12.6 years (range 4–27 years). A reoperation was needed in 45 (26.6%), of whom 14 had lesions causative of the reoperation at other than the anastomotic site. The most common causative lesion location was in the colon rather than the oral side of the small intestine. Furthermore, we investigated the relationship between presence of residual lesions following the initial surgery and lesions causative of reoperation. In the group without residual disease (n = 31), 29.0% (n = 9) had non-anastomotic lesions involved in indications for reoperation, while that was 35.7% (n = 5) in the group with residual disease (n = 14). Conclusions Anastomotic site lesion is not the only causative factor for reoperation following ICR. Regular examinations and applicable treatment with awareness that the cause of reoperation is not limited to the site of anastomosis are important in these cases.

Abstract
Technological improvements and growing sonographers' expertise boost the role of intestinal ultrasound (IUS) in assessing patients with inflammatory bowel diseases (IBD). Non-invasiveness, low cost and good reproducibility make IUS attractive. Leveraging on the Authors' long-term field experience, this review focuses on the IUS role in IBD patients' clinical management. For detecting IBD, particularly Crohn's disease, the IUS parameters - above all the evidence of a thickened bowel wall (BWT) - show very good diagnostic accuracy similar to that of MRI or CT scan. The standard IUS parameters are not accurate enough to detect inflammatory activity, but intravenous contrast-enhanced US (CEUS) is highly accurate in ruling active inflammation out. However, its routinely use remains limited in clinical practice and its parameters need standardization. IUS is accurate in detecting IBD main complications: in particular, fistulae and abscesses. As to stenosis the recent introduction of IUS-based elastographic techniques allows to differentiate prevalently inflammatory from highly fibrotic strictures. IUS proves valid also for monitoring IBD patients. In particular, the evidence of transmural healing, defined as BWT normalization, has got an important prognostic meaning, as associated with better long-term clinical outcomes. Post-surgery CD recurrence can be suggested by early IUS assessment.

Abstract
Ulcerative colitis and Crohn's disease are the principal forms of inflammatory bowel disease. Both represent chronic inflammation of the gastrointestinal tract, which displays heterogeneity in inflammatory and symptomatic burden between patients and within individuals over time. Optimal management relies on understanding and tailoring evidence-based interventions by clinicians in partnership with patients. This guideline for management of inflammatory bowel disease in adults over 16 years of age was developed by Stakeholders representing UK physicians (British Society of Gastroenterology), surgeons (Association of Coloproctology of Great Britain and Ireland), specialist nurses (Royal College of Nursing), paediatricians (British Society of Paediatric Gastroenterology, Hepatology and Nutrition), dietitians (British Dietetic Association), radiologists (British Society of Gastrointestinal and Abdominal Radiology), general practitioners (Primary Care Society for Gastroenterology) and patients (Crohn's and Colitis UK). A systematic review of 88 247 publications and a Delphi consensus process involving 81 multidisciplinary clinicians and patients was undertaken to develop 168 evidence- and expert opinion-based recommendations for pharmacological, non-pharmacological and surgical interventions, as well as optimal service delivery in the management of both ulcerative colitis and Crohn's disease. Comprehensive up-to-date guidance is provided regarding indications for, initiation and monitoring of immunosuppressive therapies, nutrition interventions, pre-, peri- and postoperative management, as well as structure and function of the multidisciplinary team and integration between primary and secondary care. Twenty research priorities to inform future clinical management are presented, alongside objective measurement of priority importance, determined by 2379 electronic survey responses from individuals living with ulcerative colitis and Crohn's disease, including patients, their families and friends.

Abstract
Ulcerative colitis and Crohn's disease are the principal forms of inflammatory bowel disease. Both represent chronic inflammation of the gastrointestinal tract, which displays heterogeneity in inflammatory and symptomatic burden between patients and within individuals over time. Optimal management relies on understanding and tailoring evidence-based interventions by clinicians in partnership with patients. This guideline for management of inflammatory bowel disease in adults over 16 years of age was developed by Stakeholders representing UK physicians (British Society of Gastroenterology), surgeons (Association of Coloproctology of Great Britain and Ireland), specialist nurses (Royal College of Nursing), paediatricians (British Society of Paediatric Gastroenterology, Hepatology and Nutrition), dietitians (British Dietetic Association), radiologists (British Society of Gastrointestinal and Abdominal Radiology), general practitioners (Primary Care Society for Gastroenterology) and patients (Crohn's and Colitis UK). A systematic review of 88 247 publications and a Delphi consensus process involving 81 multidisciplinary clinicians and patients was undertaken to develop 168 evidence- and expert opinion-based recommendations for pharmacological, non-pharmacological and surgical interventions, as well as optimal service delivery in the management of both ulcerative colitis and Crohn's disease. Comprehensive up-to-date guidance is provided regarding indications for, initiation and monitoring of immunosuppressive therapies, nutrition interventions, pre-, peri- and postoperative management, as well as structure and function of the multidisciplinary team and integration between primary and secondary care. Twenty research priorities to inform future clinical management are presented, alongside objective measurement of priority importance, determined by 2379 electronic survey responses from individuals living with ulcerative colitis and Crohn's disease, including patients, their families and friends.

[PMID: 31496630 PMCID: PMC6710184 DOI: 10.3748/wjg.v25.i31.4534] [Citation(s) in RCA: 40] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2019] [Revised: 05/28/2019] [Accepted: 07/19/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Crohn's disease (CD) can affect the entire gastrointestinal tract. Proximal small bowel (SB) lesions are associated with a significant risk of stricturing disease and multiple abdominal surgeries. The assessment of SB in patients with CD is therefore necessary because it may have a significant impact on prognosis with potential therapeutic implications. Because of the weak correlation that exists between symptoms and endoscopic disease activity, the "treat-to-target" paradigm has been developed, and the associated treatment goal is to achieve and maintain deep remission, encompassing both clinical and endoscopic remission. Small bowel capsule endoscopy (SBCE) allows to visualize the mucosal surface of the entire SB. At that time, there is no recommendation regarding the use of SBCE during follow-up. AIM To investigate the impact of SBCE in a treat-to-target strategy in patients with CD. METHODS An electronic literature search was conducted in PubMed and Cochrane library using the following search terms: "capsule endoscopy", in combination with "Crohn's disease" and "treat-to-target" or synonyms. Two authors independently reviewed titles and abstracts identified by the search strategy after duplicates were removed. Following the initial screening of abstracts, all articles containing information about SBCE in the context of treat-to-target strategy in patients with CD were included. Full-text articles were retrieved, reference lists were screened manually to identify additional studies. RESULTS Forty-seven articles were included in this review. Two indexes are currently used to quantify disease activity using SBCE, and there is good correlation between them. SBCE was shown to be useful for disease reclassification in patients who are suspected of having or who are diagnosed with CD, with a significant incremental diagnostic yield compared to other diagnostic modalities. Nine studies also demonstrated that the mucosal healing can be evaluated by SBCE to monitor the effect of medical treatment in patients with CD. This review also demonstrated that SBCE can detect post-operative recurrence to a similar extent as ileocolonoscopy, and proximal SB lesions that are beyond the reach of the colonoscope in over half of the patients. CONCLUSION SBCE could be incorporated in the treat-to-target algorithm for patients with CD. Randomized controlled trials are required to confirm its usefulness and reliability in this indication.

Abstract
Background To assess the cost and patient impact of using small bowel and colon video capsule endoscopy (SBC) for scheduled monitoring of Crohn’s disease (CD). Methods An individual-patient, decision-analytic model of the CD care pathway was developed given current practice and expert input. A literature review informed clinical endpoints with data from peer-reviewed literature. Four thousand simulated CD patients were extrapolated from summary patient data from the Project Sonar Database. Two monitoring scenarios were assessed in this population. The first scenario represented common monitoring practice (CMP) for CD (ileocolonoscopy plus imaging), while in the second scenario patients were converted to disease monitoring using SBC. The cost-effectiveness of using SBC was assessed over 20 years. The cost of switching 50% of patients to SBC was assessed over 5 years for a health-plan including 12,000 patients with CD. Uncertainty of results was assessed using probabilistic sensitivity analysis. Results All patient groups showed increased quality of life with SBC versus CMP, with the highest gain in active symptomatic patients. Over 20 years, SBC reduced costs ($313,367 versus $320,015), increased life expectancy (18.15 versus 17.9 years) and increased quality of life (8.7 versus 8.0 QALY), making it a cost-effective option. SBC was cost-effective in 71% of individuals and 78% of populations including 50 patients. A payer implementing SBC in 50% of patients over 5 years could expect a decreased cost of monitoring (–$469 mean per patient) and surgery (–$698), but increased costs for active treatments (+$717). The discounted mean annual cost of care using CMP was $22,681 per patient over 5 years. The annual savings were $1135 per SBC-patient. The total savings for the payer over 5 years were $36.5 million. Conclusion SBC is likely to be a cost-effective and cost-saving strategy for monitoring CD in the US.

Abstract
BACKGROUND In patients with inflammatory bowel disease, we strive to achieve mucosal healing, as this has been shown to decrease the risk of disease flares, hospitalization, and surgery. For this reason, we must use objective measures of mucosal healing to inform our clinical decision-making and can no longer rely on patient symptoms alone. Assessment of small bowel Crohn's disease (SBCD) is particularly challenging given its lack of accessibility via standard endoscopic techniques. Ultrasound (US) represents a readily available, cost-effective, minimally invasive, radiation-free alternative for the assessment of small bowel disease. In this study, we performed a systematic review to determine the accuracy of ultrasound in diagnosing SBCD and its complications as compared with endoscopic visualization, surgery, and/or pathology. METHODS We searched MEDLINE, EMBASE, and CENTRAL. Prospective cohort studies published up to March 2017 were reviewed. References meeting all eligibility criteria were assessed at the full-text level by 2 independent reviewers. Sensitivity and specificity were collected where available. RESULTS A total of 2817 unique references were identified. Twenty-two studies were included. All studies were at low-moderate risk of bias based on the Quality Assessment of Diagnostic Accuracy Studies criteria. Transabdominal US (TAUS) yielded moderately high sensitivity and specificity for the diagnosis of SBCD and its postoperative recurrence. Detection was more accurate for severe postoperative recurrence. The diagnostic accuracy of US in stricture and abscess detection was high. Contrast enhancement improved the detection of abscess. Diagnostic detection of fistulas was of moderate accuracy. Entero-enteric fistulization and entero-mesenteric fistulization were most clearly identified. CONCLUSIONS Ultrasound can be used to diagnose SBCD in those with known or suspected Crohn's disease. It can be used to detect postoperative recurrence and can accurately identify abscesses and fistulas, especially with the aid of contrast enhancement.

Intravenous Contrast-Enhanced Ultrasound for Assessing and Grading Postoperative Recurrence of Crohn's Disease. Dig Dis Sci 2019; 64:1640-1650. [PMID: 30604372 DOI: 10.1007/s10620-018-5432-6] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2018] [Accepted: 12/12/2018] [Indexed: 12/11/2022]
Abstract
PURPOSE The aim was to investigate the contribution of contrast-enhanced ultrasound (CEUS) to improve the results of US in the evaluation of recurrence in postsurgical Crohn's disease (CD) and establish its role in the assessment of the severity. METHODS Anastomotic site was assessed in 108 postsurgical CD patients with B-mode, color Doppler and CEUS. Bowel wall thickness (WT), transmural complications or stenosis, color Doppler grade, and bowel wall contrast enhancement (BWCE)-using time-intensity curves-were correlated with endoscopic Rutgeerts score. A receiver operating characteristic (ROC) curve was built to establish the best cutoff to predict recurrence and the severity. A US scoring system was elaborated in order to determine the grade of recurrence. RESULTS Ileocolonoscopy detected recurrence in 90 (83.3%) subjects and severe recurrence in 62. WT ≥ 3 mm had an accuracy of 90.7% in the detection of endoscopic recurrence. The combination of parameters-WT ≥ 3 mm and BWCE (≥ 46%)-demonstrated similar accuracy (90.7%). A WT ≥ 5 mm showed the best specificity (100%) for the diagnosis of recurrence and a WT ≥ 6 mm the best specificity (95.7%) for the detection of severe recurrence. The combination of sonographic parameters-WT ≥ 6 mm or WT between 5 and 6 mm with BWCE ≥ 70%, or complications-obtained the best results grading the recurrence (sensitivity, specificity, and accuracy of 90.3%, 87%, and 88.9%, respectively). CONCLUSIONS US shows high sensitivity and specificity for the diagnosis of postsurgical recurrence. When combined with CEUS, it can improve the detection of severe recurrence.

Abstract
BACKGROUND Capsule endoscopy can be used to identify the early stage of small bowel Crohn's disease (CD). We evaluated significant small bowel capsule endoscopy (SBCE) findings that can lead to early diagnosis of CD. METHODS We retrospectively accumulated clinical and SBCE data of 108 patients (63 with and 45 without CD). Types of small bowel mucosal injuries, including erosion, ulceration, and cobblestone appearance, and the alignment of diminutive lesions were compared between patients with and without CD. Inter- and intra-observer agreement in the determination of lesions was assessed in 25 pairs of SBCE from the two groups. RESULTS Under SBCE, cobblestone appearance (33% vs. 2%, p < 0.0001), longitudinal ulcers (78% vs. 20%, p < 0.0001), and irregular ulcers (84% vs. 60%, p < 0.01) were more frequently found in patients with CD. Linear erosion (90% vs. 38%, p < 0.0001) and irregular erosion (89% vs. 64%, p < 0.005) were also more frequent in patients with CD. Furthermore, circumferential (75% vs. 9%, p < 0.0001) and longitudinal (56% vs. 7%, p < 0.0001) alignment of diminutive lesions, mainly observed in the 1st tertile of the small bowel, was more frequent in patients with CD. Good intra-observer agreement was found for ulcers, cobblestone appearance, and lesion alignment. However, inter-observer agreement of SBCE findings differed among observers. CONCLUSIONS Circumferential or longitudinal alignment of diminutive lesions, especially in the upper small bowel, may be a diagnostic clue for CD under SBCE, while inter-observer variations should be cautiously considered when using SBCE.

Abstract
BACKGROUND In Crohn's disease (CD) a small bowel study-in addition to colonoscopy-is considered necessary for diagnosis/staging. In this study we re-examined the role of capsule endoscopy (CE), colonoscopy, imaging tests [magnetic resonance enterography/computed tomographic enterography (MRE/CTE)], and inflammatory markers [fecal lactoferrin and C-reactive protein (FL/CRP)] in CD patients who had undergone intestinal resection and in those who never had surgery. METHODS In this retrospective study 43 consecutive patients underwent CE because of staging/symptoms unexplained by colonoscopy/imaging. We compared colonoscopy, imaging, and FL/CRP with CE and evaluated the impact of the latter on clinical management and outcomes. RESULTS In patients who never had surgery imaging was negative with a positive CE in 8/15 (53%) of cases. Colonoscopy was insufficient for disease staging in 10/20 (50%) cases. CRP and FL were normal with a positive CE in 35% and 28% of cases, respectively. CE findings changed the management in 6/20 (30%) of cases, with 83% showing clinical/biochemical improvement after up to 15 months of follow-up. In postoperative patients CE was positive with negative imaging in 6/8 (75%) cases. Colonoscopy was insufficient for disease staging in 13/22 (59%) cases. CRP and FL were normal in 42% and 31.8% of patients with positive CE. In these patients CE findings changed the management in 12/23 (52%) cases with 83% of them showing clinical/biochemical improvement after up to 18 months of follow-up. CONCLUSIONS Omitting CE from diagnostic/staging algorithms in CD tends to underdiagnose clinically significant small bowel lesions, thus impacting on patients' management and outcomes. 10.1093/ibd/izy048_video1izy048.video15794820403001.

Abstract
As Crohn's disease (CD) is predominantly located within the small bowel, imaging of the small bowel plays an intriguing role in the primary diagnosis as well as in the monitoring of patients with CD. Intestinal ultrasound (IUS) offers several advantages over endoscopy and other imaging modalities. Obvious advantages of IUS include noninvasiveness, rapid availability and cost effectiveness. IUS has been shown to have high accuracy in detecting small bowel CD and determining intra- and extramural complications such as stenoses, fistulae and abscesses. IUS has also been shown to be highly effective in determining postoperative disease recurrence and in follow up of patients under treatment. The following review summarizes current developments in the use of IUS for the detection of small bowel lesions and complications. The aim of this review is to suggest algorithms on how to use IUS in managing patients with small bowel CD in clinical practice. Suggested applications on the use of high frequency IUS in CD are extended by discussing new developments such as contrast-enhanced ultrasonography and elastography.

Abstract
Evolution of treatment targets in IBD has increased the need for objective monitoring of disease activity to guide therapeutic strategy. Although mucosal healing is the current target of therapy in IBD, endoscopy is invasive, expensive and unappealing to patients. GI ultrasound (GIUS) represents a non-invasive modality to assess disease activity in IBD. It is accurate, cost-effective and reproducible. GIUS can be performed at the point of care without specific patient preparation so as to facilitate clinical decision-making. As compared with ileocolonoscopy and other imaging modalities (CT and MRI), GIUS is accurate in diagnosing IBD, detecting complications of disease including fistulae, strictures and abscesses, monitoring disease activity and detecting postoperative disease recurrence. International groups increasingly recognise GIUS as a valuable tool with paradigm-changing application in the management of IBD; however, uptake outside parts of continental Europe has been slow and GIUS is underused in many countries. The aim of this review is to present a pragmatic guide to the positioning of GIUS in IBD clinical practice, providing evidence for use, algorithms for integration into practice, training pathways and a strategic implementation framework.

Abstract
BACKGROUND AND AIMS The postoperative course of Crohn's disease (CD) is best predicted by ileocolonoscopy. Ultrasonography (US) has been proposed as indicator for postsurgical recurrence (PSR), but further confirmation is needed. We performed a systemic review with meta-analysis to assess the pooled diagnostic accuracy of US in the evaluation of PSR. METHODS The systematic review was performed in PubMed/MEDLINE, EMBASE, SCOPUS, and Cochrane databases to identify studies assessing the US accuracy in PSR diagnosis. A sub-analysis between bowel sonography (BS), small-intestine contrast ultrasound (SICUS), and contrast-enhanced ultrasound (CEUS) was performed. Pooling was performed using diagnostic fixed or random-effect model according with heterogeneity. RESULTS Ten studies (536 patients) met the inclusion criteria. There was no publication bias. Pooled sensitivity and specificity of US in detecting PSR were 0.94 (95% CI, 0.86-0.97) and 0.84 (95% CI, 0.62-0.94; diagnostic accuracy 90%), respectively. At sub-analysis, pooled sensitivity and specificity were 0.82 (95% CI, 0.76-0.88) and 0.88 (95% CI, 0.74-0.95) respectively for BS, with 0.99 (95% CI, 0.99-1.00) and 0.74 (95% CI, 0.73-0.74) for SICUS. Finally, an SROC curve was built to establish the best bowel wall thickness (BWT) cutoff able to predict the presence of severe PSR (Rutgeerts ≥3): a BWT ≥5.5 mm at US revealed sensitivity of 83.8% (95% CI, 73.6%-90.6%), specificity of 97.7% (95% CI, 93%-99%). CONCLUSIONS US shows high sensitivity and specificity for the diagnosis of PSR. SICUS appears more sensitive-but less specific-than BS, while the role of CEUS needs further investigation. A cutoff value of BWT ≥5.5 mm is strongly indicative of severe PSR. 10.1093/ibd/izy012_video1izy012.video15775249754001.

Abstract
Treatment of Crohn's disease (CD) is intrinsically reliant on imaging techniques, due to the preponderance of small bowel disease and its transmural pattern of inflammation. Ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) are the most widely employed imaging methods and have excellent diagnostic accuracy in most instances. Some limitations persist, perhaps the most clinically relevant being the distinction between inflammatory and fibrotic strictures. In this regard, several methodologies have recently been tested in animal models and human patients, namely US strain elastography, shear wave elastography, contrast-enhanced US, magnetization transfer MRI and contrast dynamics in standard MRI. Technical advances in each of the imaging methods may expand their indications. The addition of oral contrast to abdominal US appears to substantially improve its diagnostic capabilities compared to standard US. Ionizing dose-reduction methods in CT can decrease concern about cumulative radiation exposure in CD patients and diffusion-weighted MRI may reduce the need for gadolinium contrast. Clinical indexes of disease activity and severity are also increasingly relying on imaging scores, such as the recently developed Lémann Index. In this review we summarize some of the recent advances in small bowel CD imaging and how they might affect clinical practice in the near future.

Abstract
BACKGROUND Anastomotic recurrence is frequent in patients with Crohn's disease (CD) following ileocecal resection. The degree of endoscopic recurrence, quantified by the Rutgeerts score (RS), is correlated with the risk of clinical and surgical recurrence. Noninvasive modalities such as capsule endoscopy (CE), magnetic resonance enterography (MRE), and intestinal ultrasound (US) may yield similar information without the need for ileocolonoscopy (IC). The aim of our meta-analysis was to evaluate the accuracy of those modalities for detection of endoscopic recurrence in postoperative CD patients. METHODS We performed a systematic literature search for studies comparing the accuracy of CE, MRE, and US with IC for detection of postoperative recurrence in CD. We calculated pooled diagnostic sensitivity, specificity, diagnostic odds ratio (DOR), and area under the curve (AUC) for each comparison. RESULTS A total of 135 studies were retrieved; 14 studies were eligible for analysis. For CE, the pooled sensitivity was 100% (95% CI, 91%-100%), specificity was 69% (95% CI, 52%-83%), DOR was 30.8 (95% CI, 6.9-138), and AUC was 0.94. MRE had pooled sensitivity of 97% (95% CI, 89%-100%), specificity of 84% (95% CI, 62%-96%), DOR of 129.5 (95% CI, 16.4-1024.7), and AUC of 0.98. US had pooled sensitivity of 89% (95% CI, 85%-92%), specificity of 86% (95% CI, 78%-93%), DOR of 42.3 (95% CI, 18.6-96.0), and AUC 0.93. CONCLUSIONS CE, MRE, and US provide accurate assessment of postoperative endoscopic recurrence in CD. These modalities should gain wider use for detection of postoperative recurrence; the prognostic value of those diagnostic findings merits evaluation in further prospective studies.

Abstract
Pediatric Crohn disease is characterized by clinical and endoscopic relapses. The inflammatory process is considered to be progressive and may lead to strictures, fistulas, and penetrating disease that may require surgery. In addition, medically refractory disease may be treated by surgical resection of inflamed bowel in an effort to reverse growth failure. The need for surgery in childhood suggests severe disease and these patients have an increased risk for recurrent disease and potentially more surgery. Data show that up to 55% of patients had clinical recurrence in the first 2 years after initial surgery. The current clinical report on postoperative recurrence in pediatric Crohn disease reviews the risk factors for early surgery and postoperative recurrence, operative risk factors for recurrence, and prevention and monitoring strategies for postoperative recurrence. We also propose an algorithm for postoperative management in pediatric Crohn disease.

Abstract
Background/Aims As a result of the rapid development of medical diagnostic tools, physicians require concrete evidence to evaluate the effectiveness of the tools. We aimed to investigate the effectiveness and additional diagnostic benefits of capsule endoscopy (CE) in patients with small bowel Crohn’s disease (CD). Methods We performed a systematic search of databases, including MEDLINE, EMBASE, and the Cochrane Library, as well as eight domestic databases. Two reviewers independently screened all references. Diagnostic data from the studies were collected, and a meta-analysis was performed. Results Twenty-four studies were included. In cases of suspected CD, CE demonstrated a superior diagnostic yield compared with small bowel follow-through (SBFT) and enteroclysis (EC); however, there was no difference compared with computed tomography enterography or magnetic resonance enterography. In cases with established CD, CE demonstrated a higher diagnostic yield only compared with EC. In the detection of terminal ileum lesions, CE exhibited a significantly increased detection rate compared with ileoscopy. Conclusions The findings of our meta-analysis indicate that CE is superior to SBFT and EC in the evaluation of suspected CD cases. CE is also a more effective diagnostic modality in patients with established CD compared with EC.

Abstract
BACKGROUND AND AIMS Capsule endoscopy (CE), magnetic resonance enterography (MRE) and small bowel (SB) intestinal contrast ultrasound (SICUS) are the modalities of choice for SB evaluation. This study aimed to compare the diagnostic yield (DY) of CE to MRE and SICUS in detection and monitoring of SB CD through meta-analysis of the available literature. METHODS We performed a systematic literature search for trials comparing the accuracy of CE, MRE and SICUS for detection of active SB inflammation in patients with suspected and/or established CD. Only prospective studies comparing CE with another additional diagnostic modality were included in the final analysis. Pooled odds ratios (ORs) for the DY of the three modalities were calculated. RESULTS A total of 112 studies were retrieved; following selection, 13 studies were eligible for analysis. The DY of CE for detection of active SB CD was similar to that of MRE (10 studies, 400 patients, OR 1.17; 95% CI 0.83-1.67) and SICUS (5 studies, 142 patients, OR 0.88; 95% CI 0.51-1.53). The outcomes were similar for the subgroups of suspected versus established CD and adult versus pediatric patients. CE was superior to MRE for proximal SB CD (7 studies, 251 patients, OR 2.79; 95% CI 1.2-6.48); the difference vs SICUS was not significant. CONCLUSION CE, MRE and SICUS have similar DY for detection of SB CD in both suspected and established CD. CE is superior to MRE for detection of proximal SB disease, however the risk of capsule retention should be considered.

Abstract
BACKGROUND AND AIMS Infliximab and adalimumab are increasingly used to prevent postoperative recurrence in Crohn's disease patients. The impact of previous exposure to one or more anti-tumour necrosis factor [TNF] agents before surgery on the efficacy of anti-TNF therapy on postoperative recurrence is unknown. METHODS We performed a retrospective analysis of Crohn's disease patients who underwent surgical bowel resection with anastomosis and prophylactic treatment with anti-TNF therapy between January 2005 and June 2013. RESULTS A total of 57 consecutive Crohn's disease patients with bowel resection and anastomosis followed by prophylactic treatment with anti-TNF were included; 21 [37%] and 24 [42%] patients had a previous exposure to one and more than one anti-TNF agents, respectively; 39 patients [68%] had a surveillance colonoscopy. Cumulative rates of postoperative endoscopic recurrence at 2 years were 45.5% [26.6-69.6%] in patients exposed to two or more anti-TNFα as compared with 29.1% [11.5-48.1%] in patients exposed to one or to zero anti-TNFα before surgery [p = 0.07]. Cumulative rates of clinical recurrence at 1 year were 21.6% [9.6-44.4%] in patients exposed to two or more anti-TNFα as compared with 6.9% [1.8-25.1%] in patients exposed to zero or one anti-TNFα before surgery [p = 0.02]. Multivariable analysis identified smoking and previous exposure to two or more anti-TNFα as risk factors for Crohn's disease clinical or endoscopic postoperative recurrence (hazard ratio [HR] = 3.17; 95% confidence interval [CI]: 1.3-7.8, p = 0.01 and HR = 4.2; 95% CI: 1.8-10.2, p = 0.001, respectively). CONCLUSIONS Previous exposure to two or more anti-TNF agents was associated with a higher risk of postoperative recurrence in Crohn's disease patients.

Abstract
BACKGROUND & AIMS Video capsule endoscopy (CE) provides a noninvasive option to assess the small intestine, but its use with respect to endoscopic procedures and cross-sectional imaging varies widely. The aim of this consensus was to provide guidance on the appropriate use of CE in clinical practice. METHODS A systematic literature search identified studies on the use of CE in patients with Crohn's disease, celiac disease, gastrointestinal bleeding, and anemia. The quality of evidence and strength of recommendations were rated using the Grading of Recommendation Assessment, Development, and Evaluation (GRADE) approach. RESULTS The consensus includes 21 statements focused on the use of small-bowel CE and colon capsule endoscopy. CE was recommended for patients with suspected, known, or relapsed Crohn's disease when ileocolonoscopy and imaging studies were negative if it was imperative to know whether active Crohn's disease was present in the small bowel. It was not recommended in patients with chronic abdominal pain or diarrhea, in whom there was no evidence of abnormal biomarkers typically associated with Crohn's disease. CE was recommended to assess patients with celiac disease who have unexplained symptoms despite appropriate treatment, but not to make the diagnosis. In patients with overt gastrointestinal bleeding, and negative findings on esophagogastroduodenoscopy and colonoscopy, CE should be performed as soon as possible. CE was recommended only in selected patients with unexplained, mild, chronic iron-deficiency anemia. CE was suggested for surveillance in patients with polyposis syndromes or other small-bowel cancers, who required small-bowel studies. Colon capsule endoscopy should not be substituted routinely for colonoscopy. Patients should be made aware of the potential risks of CE including a failed procedure, capsule retention, or a missed lesion. Finally, standardized criteria for training and reporting in CE should be defined. CONCLUSIONS CE generally should be considered a complementary test in patients with gastrointestinal bleeding, Crohn's disease, or celiac disease, who have had negative or inconclusive endoscopic or imaging studies.

Abstract
The high frequency of intestinal strictures in patients with Crohn's disease and the different treatment approaches specific for each type of stenosis make the differentiation between fibrotic and inflammatory strictures crucial in management of the disease. However, there is no standardized approach to evaluate and discriminate intestinal strictures, and until now, there was no established cross-sectional imaging modality to detect fibrosis. New techniques, such as contrast-enhanced ultrasound and sonoelastography allow the assessment of vascularization and mechanical properties of stenotic bowel tissue, respectively. These techniques have shown great potential to characterize strictures in Crohn's disease. The aim of this review is to sum up the current knowledge on bowel ultrasound tools to discriminate inflammatory from fibrotic stenosis in Crohn's disease considering the most recent published studies in the field.

Abstract
Postoperative recurrence (POR) of Crohn's disease is common after surgical resection. How to best manage POR remains uncertain. Areas covered: In this review, we will first describe the natural course and the best modalities to diagnose this surgical sequela. We will then focus on the potential risk factors for relapse and highlight the main shortcomings in the current study designs and endoscopic and clinical scoring systems, which may partly explain the unexpected outcomes of recent clinical trials. Finally, we will propose a strategy to address the management of POR. Expert commentary: Anti-tumor necrosis factor (Anti-TNF) agents are the most effective therapy to prevent POR in Crohn's disease. Patient risk stratification and active monitoring with scheduled ileocolonoscopy are cornerstones of optimal POR management. Further studies are needed to address areas of uncertainty including timing and duration of therapy and the role of therapeutic drug monitoring in this setting.

Abstract
BACKGROUND Crohn disease (CD) is a chronic relapsing disease. Imaging modalities are essential for the diagnosis and assessment of CD. Small intestine contrast ultrasonography (SICUS) is a well-tolerated, noninvasive and radiation-free modality and has shown potential in CD assessment. We aimed at evaluating the diagnostic accuracy of SICUS in the detection and assessment of small-bowel lesions and complications in CD. METHODS We searched PubMed database for relevant studies published before April 24, 2016. We integrated the true positive, false positive, false negative, and true negative into the pooled estimates of sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio. Forest plots were to represent the pooled results of all studies. RESULTS Thirteen articles were finally considered eligible. The pooled sensitivity and specificity of SICUS in detecting small-bowel lesions were 0.883 (95% confidence interval (CI) 0.847-0.913) and 0.861 (95% CI 0.828-0.890), respectively. The pooled diagnostic odds ratio was 39.123 (95% CI 20.014-76.476) and the area under the curve of summary receiver operating characteristic was 0.9273 (standard error: 0.0152). In subgroup analyses, SICUS represented fine sensitivity and specificity in proximal and distal small intestine lesion, as well as in CD-related complications such as stricture, dilation, abscess, and fistula. CONCLUSION SICUS is accurate enough to make a complete assessment about the location, extent, number, and almost all kinds of complications in CD small-bowel lesions.

Onali S, Calabrese E, Petruzziello C, Lolli E, Ascolani M, Ruffa A, Sica G, Rossi A, Chiaramonte C, Pallone F, Biancone L. Post-operative recurrence of Crohn's disease: A prospective study at 5 years. Dig Liver Dis 2016; 48:489-494. [PMID: 26905749 DOI: 10.1016/j.dld.2016.01.009] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2015] [Revised: 01/04/2016] [Accepted: 01/16/2016] [Indexed: 12/11/2022]
Abstract
BACKGROUND We aimed to prospectively assess whether endoscopic recurrence severity at 1 year in Crohn's disease is predictive of clinical recurrence within 5 years. METHODS Clinical recurrence (Crohn's Disease Activity Index>150) was assessed yearly for 5 years in Crohn's disease patients undergoing ileo-colonic resection. At 1 year, recurrence was assessed by colonoscopy (Rutgeerts' score ≥i1 or ≥2i) and small intestine contrast ultrasonography. RESULTS 40 patients were included (23 males, median age 39 [16-69] years). Clinical recurrence occurred within 5 years in 16 (40%) patients (years 1, 2, 3, 4, 5: 2 [5%]; 10 [25%]; 4 [10%]; 2 [5%]; 4 [10%], respectively). At 1 year, endoscopic recurrence (score≥i1) occurred in 39 (97.5%) patients (score≥i2: 33 [82.5%]). Ultrasound detected lesions compatible with recurrence in 39/40 (97.5%) patients. Endoscopic score at 1 year was correlated with clinical score at 2 years (p=0.007; r=0.41). Endoscopic score at 1 year was higher in patients with (n=10) vs without (n=30) clinical recurrence at 2 years (3 [2-4] vs 2 [0-4]; p=0.003). Higher endoscopic score (>i2) at 1 year was a risk factor for clinical recurrence within 5 years (OR=0.18; 95% CI 0.04-0.71; p=0.008). CONCLUSIONS In Crohn's disease, severity of endoscopic recurrence at 1 year remains a predictive marker of clinical recurrence within 5 years. Small intestine contrast ultrasonography is useful for assessing 1-year recurrence.

Abstract
BACKGROUND Bowel ultrasonography (US) is considered a useful technique for assessing mural inflammation and complications in Crohn's disease (CD). The aim of this review is to appraise the evidence on the accuracy of bowel US for CD. In addition, we aim to provide recommendations for its optimal use. METHODS Publications were identified by literature search from 1992 to 2014 and selected based on predefined criteria: 15 or more patients; bowel US for diagnosing CD, complications, postoperative recurrence, activity; adequate reference standards; prospective study design; data reported to allow calculation of sensitivity, specificity, agreement, or correlation values; articles published in English. RESULTS The search yielded 655 articles, of which 63 were found to be eligible and retrieved as full-text articles for analysis. Bowel US showed 79.7% sensitivity and 96.7% specificity for the diagnosis of suspected CD, and 89% sensitivity and 94.3% specificity for initial assessment in established patients with CD. Bowel US identified ileal CD with 92.7% sensitivity, 88.2% specificity, and colon CD with 81.8% sensitivity, 95.3% specificity, with lower accuracy for detecting proximal lesions. The oral contrast agent improves the sensitivity and specificity in determining CD lesions and in assessing sites and extent. CONCLUSIONS Bowel US is a tool for evaluation of CD lesions in terms of complications, postoperative recurrence, and monitoring response to medical therapy; it reliably detects postoperative recurrence and complications, as well as offers the possibility of monitoring disease progression.

Capsule Endoscopy for Crohn's Disease: Current Status of Diagnosis and Management. Gastroenterol Res Pract 2015; 2016:8236367.

Abstract
Crohn's disease (CD) is an idiopathic inflammatory bowel disease involving the small and/or large intestine. More than 50% of Western CD patients and up to 88% of Asian CD patients may have small intestinal involvement. Video capsule endoscopy (VCE) has a higher diagnostic yield than small bowel barium radiography and computed tomography enterography for the detection of small intestinal involvement of CD. VCE also provides diagnostic yields comparable to magnetic resonance- (MR-) based enterography or enteroclysis and may have several advantages over MR-based tests for the detection of early small intestinal lesions. Several studies have suggested the use of VCE-based disease activity scoring systems to evaluate small intestinal mucosal disease activity, although their clinical relevance needs to be further studied. A possible indication for VCE is recurrence monitoring after complete surgical excision of CD-involved segments but its usefulness and efficacy compared with conventional endoscopy should be evaluated. The capsule retention rate ranges from 0 to 5.4% in suspected CD patients and from 0 to 13.2% in established CD patients. If VCE is necessary, significant small bowel stricture should be ruled out before VCE by performing a patency capsule study and/or small bowel radiological study in suspected or established CD patients.

Abstract
The introduction of wireless capsule endoscopy in 2000 has revolutionized our ability to visualize parts of the small bowel mucosa classically unreached by the conventional endoscope, and since the recent introduction of colon capsule endoscopy, a promising alternative method has been available for the evaluation of large bowel mucosa. The advantages of wireless capsule endoscopy include its non-invasive character and its ability to visualize proximal and distal parts of the intestine, while important disadvantages include the procedure’s inability of tissue sampling and significant incompletion rate. Its greatest limitation is the prohibited use in cases of known or suspected stenosis of the intestinal lumen due to high risk of retention. Wireless capsule endoscopy plays an important role in the early recognition of recurrence, on Crohn’s disease patients who have undergone ileocolonic resection for the treatment of Crohn’s disease complications, and in patients’ management and therapeutic strategy planning, before obvious clinical and laboratory relapse. Although capsule endoscopy cannot replace traditional endoscopy, it offers valuable information on the evaluation of intestinal disease and has a significant impact on disease reclassification of patients with a previous diagnosis of ulcerative colitis or inflammatory bowel disease unclassified/indeterminate colitis. Moreover, it may serve as an effective alternative where colonoscopy is contraindicated and in cases with incomplete colonoscopy studies. The use of patency capsule maximizes safety and is advocated in cases of suspected small or large bowel stenosis.

Abstract
BACKGROUND AND AIMS The structured IBD Ahead 'Optimised Monitoring' programme was designed to obtain the opinion, insight and advice of gastroenterologists on optimising the monitoring of Crohn's disease activity in four settings: (1) assessment at diagnosis, (2) monitoring in symptomatic patients, (3) monitoring in asymptomatic patients, and (4) the postoperative follow-up. For each of these settings, four monitoring methods were discussed: (a) symptom assessment, (b) endoscopy, (c) laboratory markers, and (d) imaging. Based on literature search and expert opinion compiled during an international consensus meeting, recommendations were given to answer the question 'which diagnostic method, when, and how often'. The International IBD Ahead Expert Panel advised to tailor this guidance to the healthcare system and the special prerequisites of each country. The IBD Ahead Swiss National Steering Committee proposes best-practice recommendations adapted for Switzerland. METHODS The IBD Ahead Steering Committee identified key questions and provided the Swiss Expert Panel with a structured literature research. The expert panel agreed on a set of statements. During an international expert meeting the consolidated outcome of the national meetings was merged into final statements agreed by the participating International and National Steering Committee members - the IBD Ahead 'Optimized Monitoring' Consensus. RESULTS A systematic assessment of symptoms, endoscopy findings, and laboratory markers with special emphasis on faecal calprotectin is deemed necessary even in symptom-free patients. The choice of recommended imaging methods is adapted to the specific situation in Switzerland and highlights the importance of ultrasonography and magnetic resonance imaging besides endoscopy. CONCLUSION The recommendations stress the importance of monitoring disease activity on a regular basis and by objective parameters, such as faecal calprotectin and endoscopy with detailed documentation of findings. Physicians should not rely on symptoms only and adapt the monitoring schedule and choice of options to individual situations.

Abstract
Inflammatory bowel disease (IBD) is one of the most common chronic gastrointestinal diseases in pediatric patients. Choosing the optimal imaging modality for the assessment of gastrointestinal disease in pediatric patients can be challenging. The invasiveness and patient acceptance, the radiation exposure and the quality performance of the diagnostic test need to be considered. By reviewing the literature regarding imaging in inflammatory bowel disease the value of ultrasound in the clinical management of pediatric patients is highlighted. Transabdominal ultrasound is a useful, noninvasive method for the initial diagnosis of IBD in children; it also provides guidance for therapeutic decisions and helps to characterize and predict the course of the disease in individual patients. Ultrasound techniques including color Doppler imaging and contrast-enhanced ultrasound are promising imaging tools to determine disease activity and complications. Comparative studies between different imaging methods are needed.

Abstract
Video capsule endoscopy (VCE) is an ingestible video camera that transmits high-quality images of the small intestinal mucosa. This makes the small intestine more readily accessible to physicians investigating the presence of small bowel disorders, such as Crohn's disease (CD). Although VCE is frequently performed in Korea, there are no evidence-based guidelines on the appropriate use of VCE in the diagnosis of CD. To provide accurate information and suggest correct testing approaches for small bowel diseases, the Korean Gut Image Study Group, part of the Korean Society of Gastrointestinal Endoscopy, developed guidelines on VCE. Teams were set up to develop guidelines on VCE. Four areas were selected: diagnosis of obscure gastrointestinal bleeding, small bowel preparation for VCE, diagnosis of CD, and diagnosis of small bowel tumors. Three key questions were selected regarding the role of VCE in CD. In preparing these guidelines, a systematic literature search, evaluation, selection, and meta-analysis were performed. After writing a draft of the guidelines, the opinions of various experts were solicited before producing the final document. These guidelines are expected to play a role in the diagnosis of CD. They will need to be updated as new data and evidence become available.

Abstract
Despite advances in medical management, many patients with Crohn's disease (CD) require intestinal surgery throughout their lives. Surgery is not a cure, and postoperative recurrence is common in patients with CD. Ileocolonoscopy has been considered to be the gold standard in the diagnosis and monitoring of postoperative recurrence. However, the optimal monitoring strategy for postoperative recurrence has yet to be established. Capsule endoscopy and cross-sectional imaging techniques, including ultrasonography, computed tomography and MRI, have been used in the postoperative setting, and their usefulness in the monitoring of disease activity has been evaluated in recent clinical trials. The value of fecal markers, such as calprotectin and lactoferrin, has been also assessed in several studies. This review was to identify optimized methods for the diagnosis and monitoring of postoperative recurrence in CD.

Abstract
BACKGROUND Colonic metaplasia has been described in pouchitis. In a prospective study, we investigated whether colonic phenotype may develop in Crohn's disease (CD) ileum. The expression of sulfomucins (colonic mucin), sialomucins, and CD10 (small intestine mucin and phenotype) was evaluated before and after ileocolonic resection for CD. METHODS From February 2007 to March 2010, 22 patients with CD undergoing surgery were enrolled. Clinical (Crohn's Disease Activity Index >150) and endoscopic recurrence (Rutgeerts score ≥1) rates were assessed at 6 and 12 months. Ileal samples were taken at surgery (T0), at 6 (T1), and 12 months (T2) for histology, histochemistry (High Iron Diamine-Alcian Blue), and immunohistochemistry (anti-CD10). RESULTS In 22 patients, recurrence was assessed at 6 and 12 months (clinical recurrence 9% and 18%; endoscopic recurrence 73% and 77%). In all 22 patients, ileal samples were taken at 6 and 12 months (involved area in patients with recurrence). In 19 of 22 (86.3%) patients, the involved ileum was also studied at surgery. At T0, T1, and T2, the expression of sialomucins and CD10 (small intestine mucin and phenotype) was comparable and higher (P < 0.0001) than the expression of sulfomucins (colonic mucin) (mean [range], T0:82 [35-100] versus 75 [0-100] versus 16 [0-50]; T1:96 [60-100] versus 94.7 [50-100] versus 3.89 [0-40]; T2:93.3 [60-100] versus 88.1 [25-100] versus 6.6 [0-40]). The expression of small-intestine mucin and phenotype was higher at T1 (P = 0.025) versus T0 (P = 0.026). Differently, the expression of colonic mucin was lower at T1 versus T0 (P = 0.027). CONCLUSIONS In CD, the ileum involved by severe/established lesions develops a "metaplastic" colonic mucosa phenotype. Differently, CD ileum with no lesions or with early recurrence maintains the "native" small intestine type mucin secretion and phenotype.

Abstract
Surgical treatment does not cure Crohn's disease, and postoperative recurrence is a feature of the clinical course of the disease. Ileocolonoscopy remains the gold standard for the surveillance of recurrent Crohn's disease and should be performed 6-12 months after an operation. Many other non-invasive techniques are also useful and complement endoscopy for the early diagnosis of postoperative recurrence. Anti-TNF agents show great efficacy for the prevention of postoperative recurrence, and long-term use can maintain remission. It remains undetermined whether early treatment after postoperative endoscopic recurrence is ultimately as efficacious as prophylactic therapy.

Abstract
Despite an increasing use of immunosuppressants and anti-tumor necrosis factor (TNF) agents, approximately half of the patients with Crohn's disease will require surgery within 10 years after diagnosis. Postoperative relapse is frequent and should be systematically assessed within the first year by endoscopy. Absence of prophylactic treatment is associated with a higher risk of relapse. Other risk factors include smoking, prior intestinal surgery, penetrating disease behavior, perianal location, and extensive small bowel resection. Pooled data indicate that 5-aminosalicylic acid and thiopurines have only slight efficacy to prevent postoperative recurrence in Crohn's disease. Nitroimidazole antibiotics are modestly effective, but long-term toxicity limits their use in clinical practice. Recently, anti-TNF agents in this setting have demonstrated efficacy and dramatically contrast with other interventions, but rising costs are concerning. Anti-TNF agents are highly effective in the prevention of postoperative recurrence in these patients. A therapeutic strategy based on a risk stratification of patients, with further treatment step-up and adjustment if relapse occurs on the basis of ileocolonoscopy, is recommended in clinical practice. Should we move towards top-down strategies based on a wider use of anti-TNF agents even in patients who are not at high risk of postoperative recurrence? Ongoing clinical trials addressing this issue will dramatically change our clinical practice.

Abstract
BACKGROUND Discrepancies between severity of lesions and symptoms may be observed in Crohn's disease. We prospectively assessed whether Crohn's disease may be diagnosed among asymptomatic relatives of patients, using Small Bowel Contrast Ultrasonography. METHODS Diagnosis of asymptomatic Crohn's disease relatives was defined ultrasonographically as: bowel wall thickness >3mm, bowel dilation/stricture, lumen diameter >2.5 cm. Diagnosis was confirmed by ileocolonoscopy. Subjects were also screened for the Leu3020insC mutation. RESULTS Consent was given by 35 asymptomatic first-degree relatives of 18 Crohn's disease patients. Ultrasonography indicated increased bowel wall thickness (5mm) compatible with ileal Crohn's disease in 1 relative (2.8%), a 42 year-old male. Ileocolonoscopy, histology, and radiology confirmed the diagnosis of stricturing ileal Crohn's disease. Gallbladder stones were detected in 7/35 (20%) relatives and Leu3020insC mutation in 3/35 (8.5%). CONCLUSIONS Small Bowel Contrast Ultrasonography may be a useful tool to diagnose asymptomatic small bowel Crohn's disease among first-degree relatives of patients.

Abstract
AIM To review the optimal strategy to prevent recurrence of Crohn's disease (CD) after surgery, with particular emphasis on the risk factors that predict postoperative recurrence, methods of monitoring for recurrence and medications used to prevent postoperative recurrence. METHOD MEDLINE and the Cochrane Library were searched for clinical trials and meta-analyses that studied postoperative recurrence and prophylactic medications in CD. RESULTS The most significant factor that predicted postoperative recurrence was patient smoking status. Smokers had an increased risk of recurrence (odds ratio = 2.15; 95% confidence interval (CI) = 1.42-3.27). Similarly, perforating CD appeared to be associated with a higher recurrence rate compared with nonperforating CD (hazard ratio = 1.50; 95% CI = 1.16-1.93). The optimal monitoring strategy for postoperative recurrence has yet to be established. Nonetheless, ileocolonoscopy is considered to be the gold standard. Noninvasive imaging techniques including contrast ultrasonography and capsule endoscopy appear to be useful for postoperative monitoring. A number of meta-analyses found that mesalazine, nitroimidazole antibiotics and purine analogues (azathioprine/6-mercaptopurine) significantly reduced the risk of postoperative recurrence when compared with placebo. Additionally, recent randomized controlled trials have suggested that an early intervention with infliximab is likely to prevent recurrence after ileocolonic resection. Likewise, in prospective studies, biological therapy (infliximab/adalimumab) reduced clinical and endoscopic CD activity in patients with early endoscopic recurrence after surgery. CONCLUSION Although additional evidence is necessary, endoscopic monitoring and treatment step-up should be used to prevent postoperative recurrence of CD.

Abstract
AIM The aim of this study was to assess whether the contrast-enhanced ultrasonography (CEUS) can increase the value of the ultrasonography in the study of postoperative recurrence of Crohn's disease (CD). MATERIALS AND METHODS 60 patients with CD who had previously undergone ileocolic resection underwent prospectively both CEUS and colonoscopy within a 3-day period. The sonographic examination included evaluation of bowel wall thickness, transmural complications, colour Doppler grade and contrast-enhanced US. In addition a sonographic score was established. The capacity of CEUS to diagnose endoscopic recurrence, as well as its severity, was assessed by calculating the sensitivity, specificity and positive and negative predictive values, accuracy and odds ratio, with their respective 95% confidence intervals. The areas under the receiver operating characteristic (ROC) curves were also calculated. RESULTS 49 out of 60 patients showed endoscopic postoperative recurrence. Severe endoscopic recurrence was present in 34 patients (57%). Classic ultrasound parameters (wall thickness >3mm and colour Doppler flow) revealed an accuracy of 88.3% for the diagnosis of recurrence. Sonographic score 2, including thickness >5mm or contrast enhancement >46%, improved the results with a sensitivity, specificity and accuracy of 98%, 100% and 98.3%, respectively, in the diagnosis of endoscopic recurrence. The area under the ROC curve was 0.99, in remarkable agreement with endoscopy (k: 0.946). Sonographic score 3, including thickness >5mm, contrast enhancement >70% or fistula identified 32 out of 34 (94.1%) severe endoscopic recurrences. The area under the ROC curve was 0.836, in good agreement with endoscopy (k: 0.688). CONCLUSION CEUS shows excellent sensitivity and specificity for the diagnosis of postoperative recurrence in CD and can also detect severe recurrences.

Abstract
The traditional goals of Crohn's disease therapy, to induce and maintain clinical remission, have not clearly changed its natural history. In contrast, emerging evidence suggests that achieving and maintaining mucosal healing may alter the natural history of Crohn's disease, as it has been associated with more sustained clinical remission and reduced rates of hospitalization and surgical resection. Induction and maintenance of mucosal healing should therefore be a goal toward which therapy is now directed. Unresolved issues pertain to the benefit of achieving mucosal healing at different stages of the disease, the relationship between mucosal healing and transmural inflammation, the intensity of treatment needed to achieve mucosal healing when it has not been obtained using standard therapy, and the means by which mucosal healing is defined using current endoscopic disease activity indices. The main clinical challenge relates to defining the means of achieving high rates of mucosal healing in clinical practice.

Small intestine contrast ultrasonography vs computed tomography enteroclysis for assessing ileal Crohn's disease. World J Gastroenterol 2012; 18:6088-6095.

Abstract
AIM To compare computed tomography enteroclysis (CTE) vs small intestine contrast ultrasonography (SICUS) for assessing small bowel lesions in Crohn's disease (CD), when using surgical pathology as gold standard. METHODS From January 2007 to July 2008, 15 eligible patients undergoing elective resection of the distal ileum and coecum (or right colon) were prospectively enrolled. All patients were under follow-up. The study population included 6 males and 9 females, with a median age of 44 years (range: 18-80 years). INCLUSION CRITERIA (1) certain diagnosis of small bowel requiring elective ileo-colonic resection; (2) age between 18-80 years; (3) elective surgery in our Surgical Unit; and (4) written informed consent. SICUS and CTE were performed ≤ 3 mo before surgery, followed by surgical pathology. The following small bowel lesions were blindly reported by one sonologist, radiologist, surgeon and histolopathologist: disease site, extent, strictures, abscesses, fistulae, small bowel dilation. Comparison between findings at SICUS, CTE, surgical specimens and histological examination was made by assessing the specificity, sensitivity and accuracy of each technique, when using surgical findings as gold standard. RESULTS Among the 15 patients enrolled, CTE was not feasible in 2 patients, due to urgent surgery in one patients and to low compliance in the second patient, refusing to perform CTE due to the discomfort related to the naso-jejunal tube. The analysis for comparing CTE vs SICUS findings was therefore performed in 13 out of the 15 CD patients enrolled. Differently from CTE, SICUS was feasible in all the 15 patients enrolled. No complications were observed when using SICUS or CTE. Surgical pathology findings in the tested population included: small bowel stricture in 13 patients, small bowel dilation above ileal stricture in 10 patients, abdominal abscesses in 2 patients, enteric fistulae in 5 patients, lymphnodes enlargement (> 1 cm) in 7 patients and mesenteric enlargement in 9 patients. In order to compare findings by using SICUS, CTE, histology and surgery, characteristics of the small bowel lesions observed in CD each patient were blindly reported in the same form by one gastroenterologist-sonologist, radiologist, surgeon and anatomopathologist. At surgery, lesions related to CD were detected in the distal ileum in all 13 patients, also visualized by both SICUS and CTE in all 13 patients. Ileal lesions > 10 cm length were detected at surgery in all the 13 CD patients, confirmed by SICUS and CTE in the same 12 out of the 13 patients. When using surgical findings as a gold standard, SICUS and CTE showed the exactly same sensitivity, specificity and accuracy for detecting the presence of small bowel fistulae (accuracy 77% for both) and abscesses (accuracy 85% for both). In the tested CD population, SICUS and CTE were also quite comparable in terms of accuracy for detecting the presence of small bowel strictures (92% vs 100%), small bowel fistulae (77% for both) and small bowel dilation (85% vs 82%). CONCLUSION In our study population, CTE and the non-invasive and radiation-free SICUS showed a comparable high accuracy for assessing small bowel lesions in CD.

Abstract
Two-thirds to three-quarters of Crohn's disease patients require intestinal surgery for medically refractory disease or complications. Surgery is not a cure and most patients develop recurrent Crohn's disease and require additional intestinal resections. There are a number of medications that have been investigated for preventing and treating recurrence. Risk factors for postoperative disease recurrence help guide the physician in determining the appropriate treatment strategy after Crohn's disease surgery. The approach to Crohn's disease treatment has evolved over the years. No longer should surgery be considered a failure of treatment, rather an important intervention to correct irreversible disease. In combination with a better understanding of postoperative medication strategies, patients with Crohn's disease may achieve longer term remission than previously realized. This review elucidates current understanding of the natural course of postoperative Crohn's disease, monitoring for recurrence, the risk factors for recurrence, and provides insight into an evolving new paradigm for postoperative Crohn's disease treatment.

Abstract
Ileocolonoscopy remains the gold standard in diagnosing postoperative recurrence. After excluding stricture, wireless capsule endoscopy seemed accurate in small series, but no validated score is available. Ultrasonography is a non-invasive diagnostic method reducing radiation exposure and emerging as an alternative tool for identifying post-operative recurrence. Computed tomography enteroclysis yields objective morphologic criteria that help differentiate between recurrent disease and fibrostenosis at the anastomotic site, but ionising radiation exposure limits its use. Magnetic resonance imaging may be as powerful as ileocolonoscopy in diagnosing postoperative recurrence and in predicting the clinical outcome using specific MR-scores. Biomarkers such as faecal calprotectin and faecal lactoferrin showed promising results, but their specificity in the postoperative period will require further investigation. Numerous medications have been tested to prevent and/or to treat postoperative recurrence. Efficacy of mesalamine is very low and comparable to placebo in most series. Thiopurines have modest efficacy in the postoperative setting and are associated with a high rate of adverse events leading to drug withdrawal. Antibiotics such as metronidazole or ornidazole may be effective, but toxicity and drug resistance prevent their long-term use. Anti-Tumour Necrosis Factor therapy is the most potent drug class to prevent and to treat postoperative recurrence in Crohn's disease.
