Abstract
Up to 50% of patients with Crohn's disease develop a stricture within 10 years of diagnosis. Crohn's strictures can compose of inflammation, fibrosis or smooth muscle expansion and usually a combination of these. There have been numerous new developments in imaging modalities in determining the composition of Crohn's strictures. Magnetic resonance imaging remains the best upfront imaging modality to characterize Crohn's strictures. Gastrointestinal ultrasound (GIUS) has an increasing role in clinical practice, particularly for monitoring stricture response as a treat-to-target tool. Novel imaging techniques to differentiate between fibrosis and inflammatory strictures have been developed including contrast-enhanced GIUS, strain or shear wave elastography with GIUS and multiple new magnetic resonance imaging (MRI) protocols, including diffusion weighted, delayed contrast enhancement and magnetization transfer MR protocols. However, these techniques require further validation and standardization. Regarding therapeutics, anti-tumor necrosis agents with a treat-to-target strategy have the highest quality evidence in treating strictures and can lead to stricture regression in some cases. Endoscopic balloon dilatation remains a mainstay in the treatment algorithm of treating predominantly fibrostenotic Crohn's strictures, particularly those which are symptomatic, < 5 cm in length and not causing prestenotic dilatation. Endoscopic balloon dilatation has greater effectiveness in anastomotic strictures. Surgery remains an important treatment option in Crohn's strictures, with segmental resection and stricturoplasty having their own advantages and disadvantages. Kono-S anastomosis may be superior to conventional anastomosis for endoscopic recurrence; however, further high-quality studies are required to confirm this. Using risk stratification models such as the BACARDI risk model is important to guide management decisions between a medical and surgical approach. Early post-operative medical prophylaxis with an advanced therapy is an important consideration to prevent disease recurrence. This review expands on the above topics, highlights research gaps and provides a suggested investigation and management pathway in stricturing Crohn's disease.

Abstract
BACKGROUND & AIMS Colonoscopy (CS) is the gold standard to assess postoperative recurrence (POR) in Crohn's disease (CD). However, CS is invasive and may be poorly tolerated by patients. The aim of this study was to prospectively assess the diagnostic accuracy of a noninvasive approach in detecting POR, using the endoscopic Rutgeerts' score (RS) as the reference standard. METHODS Consecutive patients with CD who underwent ileo-cecal resection were prospectively enrolled in 3 referral Italian centers. Patients underwent CS and bowel ultrasound within 1 year of surgery. Uni- and multivariable analyses were used to assess the correlation between noninvasive parameters and endoscopic recurrence, defined by a RS ≥2. RESULTS Ninety-one patients were enrolled. Sixty patients (66%) experienced endoscopic POR. The multivariable analysis identified bowel wall thickness (BWT) per 1-mm increase (odds ratio [OR], 2.43; 95% confidence interval [CI], 1.21-4.89; P = .012), the presence of mesenteric lymph nodes (OR, 15.63; 95% CI, 1.48-164.54; P = .022), and fecal calprotectin (FC) values ≥50 mcg/g (OR, 8.58; 95% CI, 2.45-29.99; P < .001) as independent predictors for endoscopic recurrence. The presence of lymph nodes or the combination of BWT ≥3 mm and FC values ≥50 mcg/g correctly classified 56% and 75% of patients, with less than 5% of patients falsely classified as having endoscopic recurrence. Conversely, the combination of BWT <3 mm and FC <50 mcg/g correctly classified 74% of patients with only 4.5% of patients falsely classified as not having endoscopic recurrence. CONCLUSIONS A noninvasive approach combining bowel ultrasound and FC can be used with confidence for detecting POR in patients with CD without the requirement for CS.

Abstract
Despite the introduction of potent biologic therapies, many patients with Crohn's disease [CD] still require an ileocolonic resection [ICR] during the course of their disease. Furthermore, the need of redo ICR has not decreased over the past few decades, highlighting the need for better strategies to prevent and treat postoperative recurrence [POR]. The first step to develop such a strategy would be to define and standardise the description of POR with adequate diagnostic instruments. In this article, we will describe the different methodologies used to report POR [endoscopic, histological, radiological, biochemical, clinical, and surgical], and review their potential benefits and limitations, as well as the optimal timing of evaluation.

Abstract
The majority of patients affected by Crohn’s disease (CD) develop a chronic condition with persistent inflammation and relapses that may cause progressive and irreversible damage to the bowel, resulting in stricturing or penetrating complications in around 50% of patients during the natural history of the disease. Surgery is frequently needed to treat complicated disease when pharmacological therapy failes, with a high risk of repeated operations in time. Intestinal ultrasound (IUS), a non-invasive, cost-effective, radiation free and reproducible method for the diagnosis and follow-up of CD, in expert hands, allow a precise assessment of all the disease manifestations: Bowel characteristics, retrodilation, wrapping fat, fistulas and abscesses. Moreover, IUS is able to assess bowel wall thickness, bowel wall stratification (echo-pattern), vascularization and elasticity, as well as mesenteric hypertrophy, lymph-nodes and mesenteric blood flow. Its role in the disease evaluation and behaviour description is well assessed in literature, but less is known about the potential space of IUS as predictor of prognostic factors suggesting response to a medical treatment or postoperative recurrence. The availability of a low cost exam as IUS, able to recognize which patients are more likely to respond to a specific therapy and which patients are at high risk of surgery or complications, could be a very useful instrument in the hands of IBD physician. The aim of this review is to present current evidence about the prognostic role that IUS can show in predicting response to treatment, disease progression, risk of surgery and risk of post-surgical recurrence in CD.

Abstract
Some evidence suggests a reduction in clinical and surgical recurrence after mesenteric resection in Crohn’s Disease (CD). The aim of the REsection of the MEsentery StuDY (Remedy) was to assess whether mesenteric removal during surgery for ileocolic CD has an impact in terms of postoperative complications, endoscopic and ultrasonographic recurrences, and long-term surgical recurrence. Among the 326 patients undergoing primary resection between 2009 and 2019 in two referral centers, in 204 (62%) the mesentery was resected (Group A) and in 122 (38%) it was retained (Group B). Median follow-up was 4.7 ± 3 years. Groups were similar in the peri-operative course. Endoscopic and ultrasonographic recurrences were 44.6% and 40.4% in Group A, and 46.7% and 41.2% in Group B, respectively, without statistically significant differences. The five-year time-to-event estimates, compared with the Log-rank test, were 3% and 4% for normal or thickened mesentery (p = 0.6), 2.8% and 4% for resection or sparing of the mesentery (p = 0.6), and 1.7% and 5.4% in patients treated with biological or immunosuppressants versus other adjuvant therapy (p = 0.02). In Cox’s model, perforating behavior was a risk factor, and biological or immunosuppressant adjuvant therapy protective for surgical recurrence. The resection of the mesentery does not seem to reduce endoscopic and ultrasonographic recurrences, and the five-year recurrence rate.

Abstract
OBJECTIVE Fetal midgut volvulus is rare and fatal, which can be easily missed on prenatal two-dimensional (2D) ultrasonography. The purpose of this study was to review our experience in prenatal diagnosis of midgut volvulus using 2D and three-dimensional (3D) ultrasound, so as to assess the diagnostic value of the two ultrasonic methods in fetal midgut volvulus. METHODS The retrospective study was conducted on 355 fetuses with intestinal dilatation diagnosed with 2D ultrasonography in the First Affiliated Hospital of Anhui Medical University from January 2017 to December 2019. All cases underwent 3D volume-rendered imaging. The diagnostic value of the two ultrasonic methods in fetal midgut volvulus was assessed. RESULTS Twelve cases of midgut volvulus were confirmed during postnatal surgery, 11 of which were correctly identified by prenatal imaging. On 2D ultrasound images, the whirlpool sign was observed in 5/12 (41%) fetuses, and of these 5 fetuses, one case also showed the coffee-bean sign. Two weeks later, another fetus showed the coffee-bean sign on ultrasound. The coffee-bean sign without the whirlpool sign was observed in two fetuses. The spiral sign was observed in 9 of the 12 cases (75%) with 3D imaging using the inversion mode. The sensitivity, specificity and accuracy of 2D ultrasound diagnosis were 83.3%, 93.3% and 93.0%, respectively. The sensitivity, specificity and accuracy of 3D ultrasound diagnosis were 91.7%, 98.3% and 98.0%, respectively. CONCLUSION Midgut volvulus should be highly suspected in the presence of intestinal dilatation and positive spiral sign on 3D volume-rendered images. Absent or decreased intestine wall echo on 2D and 3D images may be indicative of intestinal necrosis.

Abstract
Intestinal fibrosis is a late-stage phenotype of inflammatory bowel disease (IBD), which underlies most of the long-term complications and surgical interventions in patients, particularly those with Crohn's disease. Despite these issues, antifibrotic therapies are still scarce, mainly due to the current lack of understanding concerning the pathogenetic mechanisms that mediate fibrogenesis in patients with chronic intestinal inflammation. In the current review, we summarize recent evidence regarding the cellular and molecular factors of innate and adaptive immunity that are considered critical for the initiation and amplification of extracellular matrix deposition and stricture formation. We focus on the role of cytokines by dissecting the pro- vs antifibrotic components of the immune response, while taking into consideration their temporal association to the progressive stages of the natural history of IBD. We critically present evidence from animal models of intestinal fibrosis and analyze inflammation-fibrosis interactions that occur under such experimental scenarios. In addition, we comment on recent findings from large-scale, single-cell profiling of fibrosis-relevant populations in IBD patients. Based on such evidence, we propose future potential targets for antifibrotic therapies to treat patients with IBD.

Abstract
Intestinal fibrosis is one of the most common intestinal complications observed in inflammatory bowel disease, especially Crohn’s disease (CD). Intestinal fibrosis in CD is associated with chronic inflammation resulting from immunologic abnormalities and occurs as a form of tissue repair during the anti-inflammatory process. Various types of immune cells and mesenchymal cells, including myofibroblasts, are intricately involved in causing intestinal fibrosis. It is often difficult to treat intestinal fibrosis as intestinal stricture may develop despite treatment aimed at controlling inflammation. Detailed analysis of the pathogenesis of intestinal fibrosis is critical towards advancing the development of future therapeutic applications.

Abstract
Despite progress in recent decades, patients with inflammatory bowel diseases face many critical unmet needs, demonstrating the limitations of available treatment options. Addressing these unmet needs will require interventions targeting multiple aspects of inflammatory bowel disease pathology, including disease drivers that are not targeted by available therapies. The vast majority of late-stage investigational therapies also focus primarily on a narrow range of fundamental mechanisms. Thus, there is a pressing need to advance to clinical stage differentiated investigational therapies directly targeting a broader range of key mechanistic drivers of inflammatory bowel diseases. In addition, innovations are critically needed to enable treatments to be tailored to the specific underlying abnormal biological pathways of patients; interventions with improved safety profiles; biomarkers to develop prognostic, predictive, and monitoring tests; novel devices for nonpharmacological approaches such as minimally invasive monitoring; and digital health technologies. To address these needs, the Crohn's & Colitis Foundation launched IBD Ventures, a venture philanthropy-funding mechanism, and IBD Innovate®, an innovative, product-focused scientific conference. This special IBD Innovate® supplement is a collection of articles reflecting the diverse and exciting research and development that is currently ongoing in the inflammatory bowel disease field to deliver innovative and differentiated products addressing critical unmet needs of patients. Here, we highlight the pipeline of new product opportunities currently advancing at the preclinical and early clinical development stages. We categorize and describe novel and differentiated potential product opportunities based on their potential to address the following critical unmet patient needs: (1) biomarkers for prognosis of disease course and prediction/monitoring of treatment response; (2) restoration of eubiosis; (3) restoration of barrier function and mucosal healing; (4) more effective and safer anti-inflammatories; (5) neuromodulatory and behavioral therapies; (6) management of disease complications; and (7) targeted drug delivery.

Complicated Crohn’s disease (CD) will require surgical treatment during patients’ lifetime, with a considerable recurrence rate requiring additional surgery. The present study is a retrospective analysis of a prospectively maintained database in an IBD Tertiary Centre that included all the consecutive, unselected patients undergoing surgery for CD between 1993 and 2019. Patients treated with small bowel resections, colonic resections, conventional and non-conventional strictureplasties were considered. The aim was to evaluate morbidity and long-term recurrence of repeated surgery. Among the population included, the following procedures were performed: 713 (58.2%) primary surgery (group S1), 325 (26.5%) first recurrence (group S2), and 186 (15.3%) multiple recurrences (group S3). Patients undergoing repeat surgery were older (p < 0.0001) and had a longer disease duration (p < 0.0001), extended disease (p = 0.0001), shorter time frame to first surgery (p < 0.0001), nutritional impairment (p < 0.0001), and a history of aggressive medical therapy (p = 0.04). Patients undergoing surgery for recurrences required higher complexity level surgery, with more conservative approaches (p = 0.0004) and a higher ostomy number (p = 0.06). Recurrent patients had higher short bowel syndrome rate (p < 0.0001), higher minor (p = 0.04) but not major (p = 0.2) postoperative complications rate. The 10-year surgical recurrence rate was 18% for group S1, 27% for S2, and 48% for S3, with significant differences at the log-rank test. Repeated surgery for complicated CD was associated with an increased rate of minor, but not major complications, requiring high-risk surgery, with a major ostomy rate and short bowel syndrome, and is associated with an increased long-term surgical recurrence, even on strictureplasty sites.

Abstract
BACKGROUND Laparoscopy is considered the best surgical approach for Crohn's Disease (CD), and strictureplasty a reliable alternative to intestinal resection. Nevertheless, their association has never been evaluated. AIM To investigate feasibility and safety of conventional (SP) and non-conventional (NCSP) strictureplasties, using laparoscopy, for complicated CD. METHODS Starting January 2008, a prospective cohort study was performed, in consecutive, unselected patients, undergoing primary surgery for CD (Group-A). The residential database (CD-CARD) was used for the retrospective extraction of control patients (Group-B). Univariate and multi-variate analysis of pre-operative characteristics, intra-operative findings, morbidity, and intra-abdominal septic complications (IASCs) was performed. RESULTS Between January 2008 and December 2019, 331 patients received 162 SPs, 138 NCSPs, and 373 resections (Group-A). From the CD-CARD, 227 control patients received 159 SPs, 117 NCSPs, and 271 resections (Group-B) (ns). Preoperatively, Group-A presented batter nutritional status and received more biological therapies, Group-B more steroids. Group-A presented less abdominal abscesses, planned ostomies, minor complications, shorter operating time and hospitalization than Group-B, but similar major complications, IASCs and anastomotic leaks. IASCs were related to older age, elevated inflammatory indices, and preoperative treatment with high-risk drugs. CONCLUSIONS SP and NCSP are feasible by laparoscopy, with low morbidity rate, confirming the advantages of both minimally invasive and conservative surgery.

Abstract
BACKGROUND AND AIMS Post-surgical recurrence of Crohn's disease (CD) after ileocolonic resection is common. Early identification of features associated with recurrence is a standard procedure of postoperative management, but the prognostic role of such features when detected at later time points is unclear. We compared the predictivity for Crohn's disease recurrence of common clinical-instrumental variables when assessed early (<12 months) or late (>36 months) after surgery. METHODS This retrospective study considered CD patients who had ileocolonic resection and were followed for a median of 7.6 years. Clinical characteristics, post-surgical therapy, endoscopy recurrence (Rutgeerts' score ≥i2) and ultrasound features were compared between subgroups who had a early or late post-surgical assessment. Univariate and multivariate analyses were done to identify variables associated with recurrence (clinical and surgical). RESULTS Of 201 patients, 70 (32%) had a early and 39 (19%) had a late post-surgical assessment. The Early and Late subgroups had similar clinical characteristics. Overall, clinical relapse was observed in 131 patients (66%), surgical relapse in 31 (16%), endoscopic recurrence in 149 (75%) and ultrasonographic recurrence in 132 (66%), without significant differences in frequencies between subgroups. By Cox proportional hazard regression, endoscopic recurrence was a significant predictor of clinical recurrence overall (HR=2.31, P = 0.002) and in the Early (HR=3.85, P = 0.002) but not Late subgroup. DISCUSSION The most informative postoperative CD assessment is the one done within the first year of surgery. Later endoscopic evaluations have no prognostic value and should be done only for clinical needs or for research purposes.

Abstract
The evaluation of the degree of inflammation and fibrosis, intrinsic elements in intestinal wall damage of Crohn’s disease, is essential to individuate the extent of the lesions and the presence of strictures. This information will contribute to the choice of the appropriate therapeutic approach, the prediction of the response to therapy and the course of the disease. The accurate evaluation of the extent and severity of inflammation and/or fibrosis in Crohn’s disease currently requires histopathological analysis of the intestinal wall. However, in clinical practice and research, transmural assessment of the intestinal wall with cross sectional imaging is increasingly used for this purpose. The B-mode ultrasonograhic characteristics of the intestinal wall, the assessment of its vascularization by color Doppler and I.V. contrast agents, and the evaluation of the mechanical and elastic properties by sonoelastography, may provide useful and accurate information on the severity and extent of inflammation and intestinal fibrosis in Crohn’s disease. The purpose of this review is to provide an update on current sonographic methods to discriminate inflammation and fibrosis in Crohn’s disease.

Abstract
Introduction: Fibrostenosis is a hallmark of Crohn's disease (CD), remains a challenge in today's clinical management of inflammatory bowel disease patients and represents a key event in the disease course necessitating improved preventative strategies and a multidisciplinary approach to diagnosis and management. With the advent of anti-fibrotic therapies and well-defined clinical endpoints for stricturing CD, there is promise to impact the natural history of disease.Areas covered: This review summarizes current evidence in the natural history of stricturing Crohn's disease, discusses management approaches as well as future perspectives on intestinal fibrosis.Expert opinion: Currently, there are no specific therapies to prevent progression to fibrosis or to treat it after it becomes clinically apparent. In addition to the international effort by the Stenosis Therapy and Anti-Fibrotic Research (STAR) consortium to standardize definitions and propose endpoints in the management of stricturing CD, further research to improve our understanding of mechanisms of intestinal fibrosis will help pave the way for the development of future anti-fibrotic therapies.

Abstract
BACKGROUND AND AIMS Postoperative recurrence remains a challenging problem in patients with Crohn's disease [CD]. To avoid development of short bowel syndrome, strictureplasty techniques have therefore been proposed. We evaluated short- and long-term outcomes of atypical strictureplasties in CD patients with extensive bowel involvement. METHODS Side-to-side isoperistaltic strictureplasty [SSIS] was performed according to the Michelassi technique or modification of this over the ileocaecal valve [mSSIS]. Ninety-day postoperative morbidity was assessed using the comprehensive complication index [CCI]. Clinical recurrence was defined as symptomatic, endoscopically or radiologically confirmed, stricture/inflammatory lesion requiring medical treatment or surgery. Surgical recurrence was defined as the need for any surgical intervention. Endoscopic remission was defined as ≤i1, according to the modified Rutgeerts score. Deep remission was defined as the combination of endoscopic remission and absence of clinical symptoms. Perioperative factors related to clinical recurrence were evaluated. RESULTS A total of 52 CD patients [SSIS n = 12; mSSIS n = 40] were included. No mortality occurred. Mean CCI was 10.3 [range 0-33.7]. Median follow-up was 5.9 years [range 0.8-9.9]. Clinical recurrence [19 patients] was 29.7% and 39.6% after 3 and 5 years, respectively. Surgical recurrence [seven patients] was 2% and 14.1% after 3 and 5 years, respectively. At the end of the follow-up, 92% of patients kept the original strictureplasty and deep remission was observed in 25.7% of the mSSIS patients. None of the perioperative variables considered showed a significant association with clinical recurrence. CONCLUSIONS SSIS is safe, effective, and provides durable disease control in patients with extensive CD ileitis.

Abstract
Despite major advances in the inflammatory bowel diseases field, biomarkers to enable personalized and effective management are inadequate. Disease course and treatment response are highly variable, with some patients experiencing mild disease progression, whereas other patients experience severe or complicated disease. Periodic endoscopy is performed to assess disease activity; as a result, it takes months to ascertain whether a treatment is having a positive impact on disease progression. Minimally invasive biomarkers for prognosis of disease course, prediction of treatment response, monitoring of disease activity, and accurate diagnosis based on improved disease phenotyping and classification could improve outcomes and accelerate the development of novel therapeutics. Rapidly developing technologies have great potential in this regard; however, the discovery, validation, and qualification of biomarkers will require partnerships including academia, industry, funders, and regulators. The Crohn's & Colitis Foundation launched the IBD Biomarker Summit to bring together key stakeholders to identify and prioritize critical unmet needs; prioritize promising technologies and consortium approaches to address these needs; and propose harmonization approaches to improve comparability of data across studies. Here, we summarize the outcomes of the 2018 and 2019 meetings, including consensus-based unmet needs in the clinical and drug development context. We highlight ongoing consortium efforts and promising technologies with the potential to address these needs in the near term. Finally, we summarize actionable recommendations for harmonization, including data collection tools for improved consistency in disease phenotyping; standardization of informed consenting; and development of guidelines for sample management and assay validation. Taken together, these outcomes demonstrate that there is an exceptional alignment of priorities across stakeholders for a coordinated effort to address unmet needs of patients with inflammatory bowel diseases through biomarker science.

Abstract
The use of biologic agents including anti-tumor necrosis factor monoclonal antibodies followed by anti-integrins and anti-interleukins has drastically changed the treatment paradigm of Crohn’s disease (CD) by improving clinical symptoms and mucosal healing. However, up to 70% of CD patients still eventually undergo surgery mainly due to fibrostenotic strictures. There are no specific anti-fibrotic drugs yet. This review comprehensively addresses the mechanism, prediction, diagnosis and treatment of the fibrostenotic strictures in CD. We also introduce promising anti-fibrotic agents which may be available in the near future and summarize challenges in developing novel therapies to treat fibrostenotic strictures in CD.

Abstract
The Italian Society of Colorectal Surgery (SICCR) promoted the project reported here, which consists of a position statement of Italian colorectal surgeons to address the surgical aspects of Crohn's disease management. Members of the society were invited to express their opinions on several items proposed by the writing committee, based on evidence available in the literature. The results are presented, focusing on relevant points. The present paper is not an alternative to available guidelines; rather, it offers a snapshot of the attitudes of SICCR surgeons about the surgical treatment of Crohn's disease. The committee was able to identify some points of major disagreement and suggested strategies to improve quality of available data and acceptance of guidelines.

Abstract
Stricturing Crohn's disease (CD) is a significant clinical problem. The presence of a stricture may be suggested by clinical symptoms. Cross-sectional imaging using computed tomography or magnetic resonance enterography is essential in diagnosing strictures as it allows further characterization and evaluation for complications such as abscess, fistulizing disease or malignancy. Managing small bowel stricturing CD should be approached in a multidisciplinary fashion. Medical therapy can be considered in strictures which are not associated with complications, with most of the data supporting anti-TNF strategies in this setting. If the disease is refractory to medical therapy, endoscopic therapy or surgery should be performed. Endoscopic balloon dilation (EBD) is an option for short, uncomplicated and straight strictures that are within reach of a colonoscope. Although EBD has good short-term outcomes, repeat dilation is often required. Surgical options mainly include resection and strictureplasty. Strictures refractory to medical therapy, not amenable or refractory to EBD, or associated with complications or malignancy should be managed surgically. However, surgery may also be considered at an earlier stage depending on disease characteristics and patient preference. Postoperative recurrence is common, highlighting the importance of careful monitoring of the patient postoperatively and optimization of medical management accordingly. There is a pressing need to develop anti-fibrotics for the treatment of stricturing CD. This requires the development of standardized diagnostic criteria, patient-reported outcome measures and validation of endpoints in fibrostenotic CD. The STAR consortium is pioneering this effort in order to allow development and testing of anti-fibrotics in future clinical trials.

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
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
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
BACKGROUND Crohn's disease (CD) is a chronic bowel inflammation that ultimately leads to fibrosis, for which medical therapy is currently unavailable. Fibrotic strictures in CD are characterized by excessive extracellular matrix (ECM) deposition, altered balance between matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs), and overexpression of fibroblast activation protein (FAP), a marker of active fibroblasts. Here we investigated the role of FAP-targeted therapy in ECM remodeling in CD strictures ex vivo. METHODS Bowel specimens were obtained from stenotic and nonstenotic ileal segments from 30 patients with fibrostenotic CD undergoing surgery. FAP expression was evaluated in isolated mucosal myofibroblasts by immunoblotting and flow cytometry. Bowel tissue cultures were treated with anti-FAP antibody, and soluble collagen, TIMP-1, and MMPs were measured in tissue culture supernatants by immunoblotting. Anti-FAP-treated myofibroblasts were analyzed for TIMP-1 expression by immunoblotting, for migratory potential by wound healing assay, and for apoptosis by Annexin V staining. RESULTS Myofibroblasts from stenotic CD mucosa showed upregulation of FAP expression when compared with nonstenotic mucosa. Treatment of stenotic tissues with anti-FAP antibody induced a dose-dependent decrease in collagen production, particularly affecting type I collagen. The treatment also reduced TIMP-1 production in CD strictures, without altering MMP-3 and MMP-12 secretion. Accordingly, anti-FAP treatment inhibited TIMP-1 expression in stenotic CD myofibroblasts and enhanced myofibroblast migration without affecting survival. CONCLUSIONS FAP inhibition reduced type I collagen and TIMP-1 production by CD strictures ex vivo without compromising uninvolved bowel areas. These results suggest that targeting FAP could reconstitute ECM homeostasis in fibrostenotic CD.

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
In recent years, the therapeutic paradigm in Crohn's disease has shifted from a mere symptom-oriented approach, to aiming to healing of the underlying inflammation and prevention of long-term structural complications. Such 'treat-to-target' approach may allow for a more stable disease course with less hospitalizations, lower requirement for surgery and improved quality of life. In Crohn's disease, the small bowel is affected in the majority of patients; frequently, Crohn's involves only the small bowel, which remains inaccessible to conventional ileocolonoscopic techniques. Thus, non-invasive monitoring techniques are crucial for accurate disease assessment. Areas covered: This review addresses the indications and clinical implications of non-invasive small bowel monitoring modalities (magnetic resonance enterography, intestinal ultrasound, capsule endoscopy) in the assessment and management of Crohn's disease. Expert commentary: This review addresses the limitations of the current knowledge and future areas of research, including the possible utilization of transmural healing as an imaging target and the need to establish clear quantitative target values to guide treatment by imaging findings in Crohn's disease.

Abstract
BACKGROUND Stenosis is the most common complication of Crohn's disease (CD). Long-term outcome of patients receiving tumour necrosis factor (TNF) antagonists for such disease complication is poorly understood. METHODS 51 CD patients (from July 2006 to November 2015) who had a diagnosis of small bowel or colonic stenosis, diagnosed by colonoscopy and/or MRI enterography, and were treated with TNF antagonists (adalimumab or infliximab) were enrolled. The primary outcome was to assess the rate of success of TNF antagonists on avoiding abdominal surgery for stricturing CD patients. RESULTS 20 patients (39.2%) underwent surgery during the follow-up period. The overall incidence of abdominal surgery was 1.8 per 100 person-months at risk, while the median time to surgery was 37.9 months. The univariable and multivariable Cox's proportional hazards analysis of baseline parameters indicated that disease location (colonic vs ileal, HR: 28.2, 95% CI: 2.45-324, p=0.007; ileocolonic vs ileal, HR: 3.38, 95% CI: 1.09-10.5, p=0.035), prestenotic dilatation (per 1-mm increase, HR: 1.08, 95% CI: 1.01-1.15, p=0.022) and the existence of non-perianal fistula (HR: 9.77, 95% CI: 2.99-31.9, p<0.001) are independent risk factors for abdominal surgery. CONCLUSIONS In stricturing CD, anti-TNFs are effective in up to about two-thirds of the patients.

Abstract
PURPOSE OF REVIEW Intestinal fibrosis is a common complication of several enteropathies, with inflammatory bowel disease (IBD) being the major cause. Intestinal fibrosis affects both ulcerative colitis and Crohn's disease, and no specific antifibrotic therapy exists. This review highlights recent developments in this area. RECENT FINDINGS The pathophysiology of intestinal stricture formation includes inflammation-dependent and inflammation-independent mechanisms. A better understanding of the mechanisms of intestinal fibrogenesis and the availability of compounds for other nonintestinal fibrotic diseases bring clincial trials in stricturing Crohn's disease within reach. SUMMARY Improved understanding of its mechanisms and ongoing development of clinical trial endpoints for intestinal fibrosis will allow the testing of novel antifibrotic compounds in IBD.

Abstract
In the last 10 years, we have learned much about the pathogenesis, diagnosis, and management of intestinal fibrosis in patients with inflammatory bowel diseases. Just a decade ago, intestinal strictures were considered to be an inevitable consequence of long-term inflammation in patients who did not respond to anti-inflammatory therapies. Inflammatory bowel diseases-associated fibrosis was seen as an irreversible process that frequently led to intestinal obstructions requiring surgical intervention. This paradigm has changed rapidly, due to the antifibrotic approaches that may become available. We review the mechanisms and diagnosis of this serious complication of inflammatory bowel diseases, as well as factors that predict its progression and management strategies.

Abstract
Imaging in inflammatory bowel disease (IBD) plays a pivotal role in the primary diagnosis, as well as during the management of patients with known IBD. The evolution of ultrasound equipment and the growing expertise of examiners have both enhanced the role of intestinal ultrasound in the assessment of the gastrointestinal tract in IBD patients. Intestinal ultrasound has been shown to have high sensitivity and specificity, as well as high positive and negative predictive value, in the detection or exclusion of intestinal inflammatory activity in IBD. The obvious advantages of intestinal ultrasound over other imaging modalities include non-invasiveness, rapid availability and low costs. This review summarizes the current developments in the use of intestinal ultrasound for the detection of IBD and its complications, and discusses its use in the management of patients with IBD. Indications for the use of intestinal ultrasound in daily practice are presented, expanded by new developments such as contrast-enhanced ultrasonography and elastography.

Abstract
The implementation of cross-sectional imaging techniques for the clinical management of Crohn's disease patients has steadily grown over the recent years, thanks to a series of technological advances, including the evolution of contrast media for magnetic resonance, computed tomography and bowel ultrasound. This has resulted in a continuous improvement of diagnostic accuracy and capability to detect Crohn's disease-related complications. Additionally, a progressive widening of indications for cross-sectional imaging in Crohn's disease has been put forward, thus leading to hypothesize that in the near future imaging techniques can increasingly complement endoscopy in most clinical settings, including the grading of disease activity and the assessment of mucosal healing or Crohn's disease post-surgical recurrence.

Abstract
Fibrosis in inflammatory bowel disease (IBD) is a largely unresolved clinical problem. Despite recent advances in anti-inflammatory therapies over the last few decades, the occurrence of intestinal strictures in Crohn's disease patients has not significantly changed. No antifibrotic therapies are available. This journal supplement will address novel mechanisms of intestinal fibrosis, biomarker and imaging techniques and is intended to provide a roadmap toward antifibrotic therapies in IBD.

Abstract
Background Intestinal fibrosis and liver fibrosis represent a significant burden for our patients and health-care systems. Despite the severe clinical problem and the observation that fibrosis is reversible, no specific antifibrotic therapies exist. Summary In this review, using an 'East-West' scientific collaboration, we summarize the current knowledge on principal mechanisms shared by intestinal fibrosis and liver fibrosis. We furthermore discuss inflammation as the cause of fibrogenesis in both entities, depict unique features of intestinal and hepatic fibrosis, and provide a future outlook on the development of antifibrotic therapies. Key Messages A collaborative effort in the field of fibrosis, covering multiple organ systems, will have the highest chance of leading to the development of a successful antifibrotic intervention.

Abstract
Intestinal fibrosis is a common feature of Crohn's disease and may appear as a stricture, stenosis, or intestinal obstruction. Fibrostenosing Crohn's disease leads to a significantly impaired quality of life in affected patients and constitutes a challenging treatment situation. In the absence of specific medical antifibrotic treatment options, endoscopic or surgical therapy approaches with their potential harmful side effects are frequently used. However, our understanding of mechanisms of fibrogenesis in general and specifically intestinal fibrosis has emerged. Progression of fibrosis in the liver, lung, or skin can be halted or even reversed, and possible treatment targets have been identified. In face of this observation and given the fact that fibrotic alterations in various organs of the human body share distinct core characteristics, this article aims to address whether reversibility of intestinal fibrosis may be conceivable and to highlight promising research avenues and therapies.

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
The assessment of extent and severity of IBD is crucial for directing treatment decisions. Clinical symptoms alone are neither sensitive nor specific for the assessment of lesion severity in IBD. Cross-sectional imaging techniques, as well as small-bowel capsule endoscopy (SBCE) and device-assisted enteroscopy, have a high accuracy for assessing the extent of mucosal lesions, and are reliable alternatives to ileocolonoscopy. New endoscopic techniques and devices are emerging for improved follow-up and surveillance. In this Review, we discuss different imaging techniques that are used to assess IBD activity and to survey patients with IBD, and highlight the latest developments in each area. Moreover, technical improvements and new tools that aim to measure intestinal fibrosis, postoperative recurrence, activity indices and endoscopic features are analysed. All of these imaging techniques are aimed at changing the paradigm from symptom-driven to lesion-driven treatment of IBD.

Abstract
The management of patients with IBD requires evaluation with objective tools, both at the time of diagnosis and throughout the course of the disease, to determine the location, extension, activity and severity of inflammatory lesions, as well as, the potential existence of complications. Whereas endoscopy is a well-established and uniformly performed diagnostic examination, the implementation of radiologic techniques for assessment of IBD is still heterogeneous; variations in technical aspects and the degrees of experience and preferences exist across countries in Europe. ECCO and ESGAR scientific societies jointly elaborated a consensus to establish standards for imaging in IBD using magnetic resonance imaging, computed tomography, ultrasonography, and including also other radiologic procedures such as conventional radiology or nuclear medicine examinations for different clinical situations that include general principles, upper GI tract, colon and rectum, perineum, liver and biliary tract, emergency situation, and the postoperative setting. The statements and general recommendations of this consensus are based on the highest level of evidence available, but significant gaps remain in certain areas such as the comparison of diagnostic accuracy between different techniques, the value for therapeutic monitoring, and the prognostic implications of particular findings.

Abstract
BACKGROUND Infliximab has shown efficacy at preventing post operative recurrence (POR) of Crohn's disease (CD). This study aimed at evaluating whether adalimumab can prevent and treat POR of CD. METHODS This prospective, single-center, open-label, two-year study included 23 patients who had undergone ileocecal resection for refractory or complicated CD and were at high-risk for POR. Patients received adalimumab from post operative day 14 (Group I, n=8) or at 6 months post operatively after confirmation of endoscopic recurrence (PO-ER) despite treatment with azathioprine, infliximab, or 5-ASA (patients intolerant to infliximab and azathioprine, Group II, n=15). Symptom assessment and laboratory tests were performed at monthly visits. Endoscopic findings were graded using the Rutgeerts score (RS) at 6 and 24 months after initiation of adalimumab. Primary end-points were maintenance (group I) or achievement of mucosal healing (Group II). Secondary end-points were prevention of post operative clinical recurrence (PO-CR) (Group I) and endoscopic and clinical improvement (group II). RESULTS In Group I, PO-ER (RS≥i2) was seen in one patient at 6 months PO, whereas a second patient developed PO-ER and PO-CR after 24 months of treatment. In Group II, all patients had PO-ER whereas 9 (60%) patients had PO-CR at study enrolment; after 24 months of treatment 9/15 (60%) patients achieved complete (RS-i0, n=3) or near complete (RS-i1, n=6) mucosal healing and 5/9 (56%) clinical remission. No serious adverse events were reported. CONCLUSIONS This pilot study suggests that adalimumab may prevent PO-ER and treat PO-ER/CR in high risk patients for POR of CD.

Abstract
Despite improved immunosuppressive therapy, surgical resection is still often required for uncontrolled inflammatory disease and the stenosing and perforating complications of Crohn's disease. However, surgery is not curative. A majority of patients develop disease recurrence at or above the anastomosis. Subclinical endoscopically identifiable recurrence precedes the development of clinical symptoms; identification and treatment of early mucosal recurrence may therefore prevent clinical recurrence. Therapy to achieve mucosal healing should now be the focus of postoperative therapy. A number of clinical risk factors for the development of earlier postoperative recurrence have been identified, and reasonable evidence is now available regarding the efficacy of drug therapies in preventing recurrence. This evidence now needs to be incorporated into prospective treatment strategies.

Abstract
The majority of patients diagnosed with Crohn's disease eventually require surgical intervention. Unfortunately, postsurgical remission tends to be short lived; a significant number of patients experience clinical relapse and many require additional operations. The pathogenesis of this postoperative recurrence is poorly understood and, currently, there are no reliable tools to predict when and in whom the disease will recur. Furthermore, the postoperative prophylaxis profiles of available Crohn's disease therapeutic agents such as 5-aminosalicylates, immunomodulators, steroids and probiotics have been disappointing. Recently, the combination of antibiotics and azathioprine in selected high-risk patients has demonstrated some potential for benefit. The goal of the present article is to provide a coherent summary of previous and new research to guide clinicians in managing the challenging and complex problem of postoperative Crohn's disease recurrence.

Abstract
Transabdominal bowel sonography is a fast, efficient, and cheap way of examining the intestines. It is also virtually hazard-free and well accepted by patients. During the last 20 years, it has been established as a procedure for detecting bowel disease early in the diagnostic workup. Although rather unspecific, the method is sensitive for detection of bowel disease and can be applied to find the extent and location of inflammatory bowel disease. In patients with known ulcerative colitis and Crohn disease, it can also be used for follow-up because it is easily repeatable and radiation-free. Because it can be applied to find both intraluminal and peri-intestinal pathological features, it is a particularly valuable tool for the detection of complications of Crohn disease as stenosis, fistulas, and abscesses. Neither B-mode nor Doppler techniques have been proven obviously useful in categorizing disease activity, but new techniques using intravenous contrast might come closer to solving this question. Finally, recent longitudinal studies using transabdominal bowel sonography show that it can also give important prognostic information and be used for monitoring the effect of therapy.

Abstract
Prospective study carried out on 24 consecutive patients with Crohn's Disease, using sonography to assess changes caused by biological therapy and its relationship with the clinical-biological response. The Crohn's Disease Activity Index, the plasma concentration of C-reactive protein and abdominal sonograms (to assess the thickness and Doppler flow grade of the bowel wall and to detect the presence of any complications) were carried out one week prior to the induction treatment and two weeks after. The biological therapy induced remission or a partial response in 46% and 25% of the patients, respectively. It also caused a significant reduction in the thickness of the bowel wall (P = 0.005) and Doppler flow (P = 0.02), leading to the disappearance of complications in 50% of the patients. Sonographic changes were significantly more marked in patients who achieved some type of clinical-biological response, in such a way that sonograms were improved in 65% (P = 0.001) and complications disappeared in 100% of patients (P = 0.005) compared to those patients who did not respond to treatment. However, sonographic normality was only achieved in five out of 17 (29%) reactive patients (P = 0.27). This fact may support the use of sonography as a technique for optimizing the biological treatment of Crohn's Disease.

Abstract
OBJECTIVE Abdominal bowel ultrasound (US) is widely used in the management of Crohn's disease (CD). The aim of this study was to evaluate the prognostic role of bowel-wall US morphology on the short-term risk of surgery. MATERIAL AND METHODS The 147 CD patients recruited in a case-control study comprised 49 cases operated on within 30 days after US examination and 98 matched non-operated controls. Clinical and US characteristics were analysed. Bowel-wall thickness was recorded, bowel-wall patterns were grouped into five types, but for final analysis they were grouped as "preserved" or "disrupted stratification". RESULTS Wall thickness and US patterns were significantly different between cases and controls (p<0.0001). A wall thickness >4.5 mm was observed in 45/49 cases and 47/98 controls (OR = 12.21), while "disrupted stratification" was observed in 34/49 cases and 12/98 controls (OR = 16.24). Among the clinical and US characteristics recorded, only 4 US variables were independently associated with surgery (pattern, thickness, presence of fistulae/abscesses and stenoses) and considered for the US score=(2.5*US pattern)+(1.5*Bowel thickness)+(3*Presence of fistulae/abscesses)+(1.5*Presence of stenoses). Based on this score, up to 84% of patients were correctly classified according to actual status (operated/non-operated). CONCLUSIONS Although it needs further prospective validation, the score we propose seems to be a reliable prognostic marker for the short-term risk of surgery in CD. In particular, the score points out those patients with an impending risk of surgery who need careful and frequent control in order to decide on the right time for surgery.

Abstract
In the last two decades, there has been substantial development in the diagnostic possibilities for examining the small intestine. Compared with computerized tomography, magnetic resonance imaging, capsule endoscopy and double-balloon endoscopy, ultrasonography has the advantage of being cheap, portable, flexible and user- and patient-friendly, while at the same time providing the clinician with image data of high temporal and spatial resolution. The method has limitations with penetration in obesity and with intestinal air impairing image quality. The flexibility ultrasonography offers the examiner also implies that a systematic approach during scanning is needed. This paper reviews the basic scanning techniques and new modalities such as contrast-enhanced ultrasound, elastography, strain rate imaging, hydrosonography, allergosonography, endoscopic sonography and nutritional imaging, and the literature on disease-specific findings in the small intestine. Some of these methods have shown clinical benefit, while others are under research and development to establish their role in the diagnostic repertoire. However, along with improved overall image quality of new ultrasound scanners, these methods have enabled more anatomical and physiological changes in the small intestine to be observed. Accordingly, ultrasound of the small intestine is an attractive clinical tool to study patients with a range of diseases.

Abstract
BACKGROUND & AIMS Several bowel-sparing techniques have been proposed for treating patients with CD, but there have been no prospective studies analyzing risk factors and long-term outcome. We prospectively evaluated safety and long-term efficacy of conservative surgery for patients with complicated CD. METHODS From 1993-2007, 393 of 502 consecutive patients underwent surgery for complicated CD of the small bowel. Those with colonic involvement were excluded. The Student t test, chi(2) test, Kaplan-Meier estimates, and Cox proportional hazard model were used to analyze postoperative complications and long-term outcome. RESULTS A total of 865 jejunoileal segments underwent 318 small bowel resections and 367 strictureplasties (either classic or nonconventional). There were no deaths; the complication rate was 5.6%, and the cumulative 10-year recurrence rate was 35%. None of the prognostic factors were correlated with postoperative complications. Younger age, an upper jejunoileal location, stricturing behavior, and small-bowel wall thickening 12 months after surgery showed hazard ratios of 2.4 (95% confidence interval [CI], 1-5.4; P = .03), 2.5 (95% CI, 1.3-4.7; P = .004), 2.2 (95% CI, 1.1-4.1; P = .01), and 4.5 (95% CI, 2.3-8.6; P = .000), respectively. Immunomodulator therapy failed to reduce long-term surgical recurrence. CONCLUSIONS Young patients with extended and stricturing disease are at high risk for disease recurrence after surgery. Bowel wall thickening was a reliable prognostic factor for these patients. Conservative surgery is safe and effective in treating patients with jejunoileal CD and should be considered as the first-line surgical treatment, preventing the risk of short bowel syndrome caused by repeated resections.

Abstract
BACKGROUND Mesenteric adipose tissue hypertrophy is a frequent sonographic finding in Crohn's disease (CD). This study assessed its sonographic prevalence, the correlation with the degree of clinical or biochemical activity of the disease, and its impact on disease outcome in CD patients. METHODS In all, 185 consecutive CD patients underwent bowel ultrasound to assess the presence of mesenteric fat tissue alteration as well as thickness and echopattern of the bowel wall, site and extent of CD, and presence of stenosis, fistulas, and abscesses. Clinical and biochemical parameters of disease activity were also assessed. Multiple logistic regression analysis was used to identify variables related to mesenteric adipose tissue alteration. RESULTS Mesenteric adipose tissue alteration, detected in 88 (47.6%) patients, showed a significant correlation both with clinical and biochemical CD activity and with internal fistulas, bowel wall thickness, and length of thickened bowel wall. Logistic regression analysis showed that internal fistulas (odds ratio [OR] = 13.5), thickened bowel wall (OR = 7.6), C-reactive protein (OR = 6.1), CD Activity Index (CDAI) (OR = 3.1), and length of diseased bowel walls (OR = 2.6) were significantly associated with mesenteric adipose tissue alteration. Of the 111 patients with quiescent CD, 22 showed mesenteric adipose tissue hypertrophy. These patients did not show increased risk of relapse compared with quiescent patients without mesenteric fat alteration. CONCLUSIONS Mesenteric adipose tissue alteration is correlated with biochemical and clinical activity of CD and with internal fistulas and increased bowel wall thickness. In quiescent CD, mesenteric hypertrophy does not appear to be a risk factor of relapse.
