Project description:BackgroundEvidence for endoscopic balloon dilation of small intestinal strictures in Crohn's disease (CD) using balloon-assisted enteroscopy is scarce.AimTo evaluate endoscopic balloon dilation for the treatment of small intestinal CD strictures using balloon-assisted enteroscopy.MethodsCitations in Embase, MEDLINE, and Cochrane were systematically reviewed. In a meta-analysis of 18 studies with 463 patients and 1189 endoscopic balloon dilations, technical success was defined as the ability to dilate a stricture. Individual data were also obtained on 218 patients to identify outcome-relevant risk factors.ResultsIn the pooled per-study analysis, technical success rate of endoscopic balloon dilation was 94.9%, resulting in short-term clinical efficacy in 82.3% of patients. Major complications occurred in 5.3% of patients. During follow-up, 48.3% of patients reported symptom recurrence, 38.8% were re-dilated and 27.4% proceeded to surgery. On the per-patient-based multivariable analysis, that patients with disease activity in the small intestine had lower short-term clinical efficacy (odds ratio 0.32; 95% confidence interval 0.14-0.73, P = 0.007). Patients with concomitant active disease in the small and/or large intestine had an increased risk to proceed toward surgery (hazard ratio 1.85; 95% confidence interval 1.09-3.13, P = 0.02 and hazard ratio 1.77; 95% confidence interval 1.34-2.34, P < 0.001).ConclusionsBalloon-assisted enteroscopy for dilatation of CD-associated small intestinal strictures has high short-term technical and clinical efficacy and low complication rates. However, up to two-thirds of patients need re-dilation or surgery.

Project description:BackgroundVideocapsule endoscopy (VCE) and double-balloon enteroscopy (DBE) are part of the diagnostic and therapeutic work-up of indications other than suspected small bowel bleeding (OSBB). The literature is currently lacking studies describing these procedures in this particular setting.ObjectivesWe assessed the clinical impact of VCE and DBE in a large monocentric cohort of OSBB patients, as compared to a control group of suspected small bowel bleeding (SSBB) patients who underwent enteroscopy over the same period.DesignMonocentric, retrospective, cohort study.MethodsWe collected the data of consecutive patients with OSBB undergoing VCE and/or DBE from March 2001 to July 2020. The demographic and clinical parameters of the patients, technical characteristics, and adverse events for each procedure were collected. The impact of VCE and DBE was defined in terms of diagnostic yield (DY). The patients were subdivided according to the main indication into four groups: celiac disease, Crohn's disease (CD), neoplasia, and persistent gastrointestinal symptoms.ResultsA total of 611 VCEs and 387 DBEs were performed for OSBB. The main indications were complicated celiac disease and CD. The DYs of VCE and DBE overall were 53 and 61.7%, respectively, with some variance among the four groups. We report no statistical differences in the DY of VCE and DBE in SSBB vs OSBB (57.7% vs 53%, p = 0.0859 and 68.8% vs 61.7%, p = 0.0582, respectively). OSBB patients were significantly younger than those with SSBB. However, similarly to SSBB (k = 0.059), poor agreement between the enteroscopic techniques was found in the OSBB population (k = 0.109). The safety of both procedures in OSBB was comparable to that in SSBB patients.ConclusionVCE and DBE are effective and safe in suspected OSBB, where their role is similar to that in SSBB, their main indication.

Project description:PurposeTo quantify bowel motility shown on cine MRI using the classical optical flow algorithm and compare it with balloon-assisted enteroscopy (BAE) findings in patients with Crohn's disease (CD).MethodsThis retrospective study included 29 consecutive patients with CD who had undergone MR enterocolonography (MREC) and BAE between March and May 2017. We developed computer software to present motion vector magnitudes between consecutive cine MR images as bowel motility maps via a classical optical flow algorithm using the Horn-Schunck method. Cine MR images were acquired with a balanced steady-state free precession sequence in the coronal direction to capture small bowel motility. The small bowels were divided into three segments. In total, 63 bowel segments were assessed via BAE and MREC. Motility scores on the maps, simplified MR index of activity (sMaRIA), and MREC score derived from a 5-point MR classification were assessed independently by two radiologists and compared with the CD endoscopic index of severity (CDEIS). Correlations were assessed using Spearman's rank coefficient. The areas under the receiver-operating characteristic curve (AUCs) of motility score for differentiating CDEIS was calculated; a P value < 0.05 was considered statistically significant.ResultsMotility score was negatively correlated with CDEIS (r = -0.59 [P < 0.001] and -0.54 [P < 0.001]), and the AUCs of motility scores for detecting CDEIS ≥ 3 were 88.2% and 78.6% for observers 1 and 2, respectively. There were no significant differences in the AUC for detecting CDEIS ≥ 3 and CDEIS ≥ 12 between motility and sMaRIA or MREC score.ConclusionThe motility map was feasible for locally quantifying the bowel motility. In addition, the motility score on the map reflected the endoscopic inflammatory activity of each small bowel segment in patients with CD; hence, it could be used as a tool in objectively interpreting cine MREC to predict inflammatory activity in CD.

Project description:BackgroundThe diagnosis of isolated small bowel Crohn's disease (ISBCD) has always been challenging.AimsThis study is aimed at comparing the clinical features and double-balloon enteroscopy (DBE) characteristics of ISBCD with those of other small bowel ulcerative diseases (OSBUD).MethodsPatients with coexisting colonic and/or ileal valve lesions (n = 45) or whose final diagnosis was not determined (n = 29) were excluded. One hundred thirty-nine patients with ISBCD and 62 patients with OSBUD found by DBE were retrospectively analyzed.ResultsThe age of ISBCD onset was lower than that of OSBUD (OR 0.957, 95% CI 0.938-0.977, p < 0.001). Abdominal pain was more common in ISBCD (OR 4.986, 95% CI 2.539-9.792, p < 0.001). Elevated fibrinogen levels (OR 1.431, 95% CI 1.022-2.003, p = 0.037) and lower levels of D-dimer (OR 0.999, 95% CI 0.999-1.000, p = 0.017) were also more supportive of the diagnosis of ISBCD. Nonsteroidal anti-inflammatory drugs (NSAIDs) used for more than two weeks decreased the probability of a diagnosis of ISBCD (OR 0.173, 95% CI 0.043-0.695, p = 0.013). Abdominal computed tomography revealed a higher proportion of skip lesions in ISBCD than in OSBUD (OR 9.728, 95% CI 3.676-25.742, p < 0.001). The ulcers of ISBCD were more distributed in the ileum (111 (79.9%) vs. 29 (46.8%), p < 0.001), and their main morphology differed in different intestinal segments. Longitudinal ulcers (OR 14.293, 95% CI 4.920-41.518, p < 0.001) and large ulcer (OR 0.128, 95% CI 0.044-0.374, p < 0.001) contributed to the differentiation of ISBCD from OSBUD. We constructed a diagnostic model, ISBCD index (AUROC = 0.877, 95% CI: 0.830-0.925), using multifactorial binary logistic regression to help distinguish between these two groups of diseases.ConclusionClinical features, laboratory tests, abdominal computed tomography, DBE characteristics, and pathology help to distinguish ISBCD from OSBUD.

Project description:ObjectiveEffective medical therapy and validated trial outcomes are lacking for small bowel Crohn's disease (CD) strictures. Histopathology of surgically resected specimens is the gold standard for correlation with imaging techniques. However, no validated histopathological scoring systems are currently available for small bowel stricturing disease. We convened an expert panel to evaluate the appropriateness of histopathology scoring systems and items generated based on panel opinion.DesignModified RAND/University of California Los Angeles methodology was used to determine the appropriateness of 313 candidate items related to assessment of CD small bowel strictures.ResultsIn this exercise, diagnosis of naïve and anastomotic strictures required increased bowel wall thickness, decreased luminal diameter or internal circumference, and fibrosis of the submucosa. Specific definitions for stricture features and technical sampling parameters were also identified. Histopathologically, a stricture was defined as increased thickness of all layers of the bowel wall, fibrosis of the submucosa and bowel wall, and muscularisation of the submucosa. Active mucosal inflammatory disease was defined as neutrophilic inflammation in the lamina propria and any crypt or intact surface epithelium, erosion, ulcer and fistula. Chronic mucosal inflammatory disease was defined as crypt architectural distortion and loss, pyloric gland metaplasia, Paneth cell hyperplasia, basal lymphoplasmacytosis, plasmacytosis and fibrosis, or prominent lymphoid aggregates at the mucosa/submucosa interface. None of the scoring systems used to assess CD strictures were considered appropriate for clinical trials.ConclusionStandardised assessment of gross pathology and histopathology of CD small bowel strictures will improve clinical trial efficiency and aid drug development.

Project description:BACKGROUND:Owing to the development of double-balloon enteroscopy (DBE) and video capsule endoscopy (VCE) in recent years, direct visualization of the entire small intestinal mucosa has become possible. Because of the nonspecific symptoms and the anatomic location of the small bowel, diagnosis of isolated small bowel Crohn's disease (CD) remains a challenge. The aim of this research was to explore the value of DBE for isolated small bowel CD in situations where routine tests cannot confirm the diagnosis. METHODS:This study included patients with suspected isolated small bowel CD who were hospitalized in Shengjing Hospital from April 2014 to June 2018. We included patients presenting with chronic diarrhea, abdominal pain, abdominal mass, perianal lesions, and systemic symptoms including weight loss, fever, and anemia after excluding infection factors. Patients with purely colonic CD were excluded from this cohort. Patients with suspected isolated small bowel CD underwent DBE. RESULTS:In 16/18 patients, pathological findings were detected by DBE. In 12 of the cases, small bowel CD was confirmed. The remaining four patients were diagnosed with small bowel inflammation, duodenal carcinoma, ileum inflammation and small bowel ulcers. However, the diagnosis of CD was confirmed in 14/18 (78%) patients by taking into account the clinical presentation, endoscopic and histological results as well as the experimental treatment. DBE assisted in the diagnosis in 86% (12/14) of the patients. CONCLUSIONS:In the diagnosis of small bowel CD, DBE is a helpful tool. Before assessment with DBE, clinical features, colonoscopy, and CT were used to initially assess the intestine. According to the lesions indicated by CT, we chose the most appropriate endoscope insertion route, and combined the endoscopic characteristics and pathological results of DBE to confirm the diagnosis.

Project description:BackgroundsEndoscopic stricturotomy (ESt) has been shown to be effective in treating inflammatory bowel disease (IBD)-associated anastomotic strictures. However, the outcome of ESt in benign, non-IBD conditions has not been described. The aim of this study was to evaluate the outcome of ESt in the management of IBD and non-IBD-associated strictures.MethodsData of all consecutive IBD and non-IBD patients with benign anastomotic strictures treated with ESt from 2009 to 2016 were extracted. The primary outcomes were surgery-free survival and procedure-related complications.ResultsA total of 49 IBD and 15 non-IBD patients were included in this study. The IBD group included 25 patients with Crohn's disease and 24 with ulcerative colitis and ileal pouches. Underlying diseases in the non-IBD group included colorectal cancer (n = 7), diverticulitis (n = 5), large bowel prolapse (n = 2), and constipation (n = 1). Immediate technical success was achieved in all patients in both groups. Bleeding complications occurred on five occasions (4.7% per procedure) in the IBD group, while no complication occurred in the non-IBD group (P = 0.20). Stricture improvement on follow-up endoscopy was found in 10 (20.4%) and 5 (33.3%) patients in the IBD and non-IBD groups, respectively (P = 0.32). Six (12.2%) patients in the IBD group and four (26.7%) patients in the non-IBD group eventually required stricture-related surgery (P = 0.23). IBD patients appeared to have a higher tendency for maintaining surgery-free after the procedure than non-IBD patients (P = 0.08).ConclusionsEndoscopic stricturotomy was shown to have comparable outcomes, though non-IBD patients seem to have a higher need for subsequent surgery but a lower complication rate than IBD patients.

Project description:Device-assisted enteroscopy (DAE) enables the direct visualization of small bowel lesions with histological diagnosis; however, few studies have described the diagnostic performance of enteroscopic biopsy. We investigated the diagnostic performance of enteroscopic biopsy. We used a nationwide multicenter enteroscopy database to identify patients who underwent DAE with biopsy for small bowel diseases. The patients were classified into the tumor and non-tumor groups according to the final diagnosis. They were also divided into diagnostic and non-diagnostic groups based on the enteroscopic biopsy results. The clinical significance of the first biopsy and histological diagnostic yield of DAE were analyzed. Among the 112 procedures investigated, 32 (28.9%) were diagnosed with tumors, and 80 (71.7%) were diagnosed with non-tumor diseases. The overall histological diagnostic yield of DAE was 43.7%. The histological diagnostic yield was significantly higher in the tumor than in the non-tumor group (81.2% vs. 28.8%, p < 0.001). The mean number of biopsies was significantly higher in the diagnostic than in the non-diagnostic group (5.6 ± 3.3 vs. 3.7 ± 2.1, p = 0.001). In the diagnostic group, 87.7% of the cases were histologically confirmed at the first biopsy. Therefore, the first biopsy should be performed carefully.
