Abstract Background In the majority of patients, the areas of the intestine affected in Crohn’s disease (CD) are the terminal ileum and less commonly the rectum. The terminal ileum is affected in the majority of genetic animal models of CD as well. Additionally, CD recurs at sites of tight anastomosis or strictures postoperatively. These observations lead to the assumption that increased intraluminal pressure related to the presence of a valve, sphincter or stenosis is associated with CD pathogenesis. We investigated the hypothesis that the creation of a partial intestinal stenosis could have an impact on disease severity, in a genetic animal model of CD (TNFΔare/+). TNFΔare/+ mice overexpress TNFα leading to a Crohn-like colitis in the terminal ileum. Methods Twenty-nine TNFΔare/+ mice, 6 weeks old, were divided into three intervention groups: stenosis, sham and control. In the stenosis group (n = 11), a partial small bowel obstruction was created via a novel triple suture technique, approximately 3 cm from the ileocecal valve. In the control group (n = 9), a loose single suture was placed at the aforementioned site to test the direct effect of the foreign material on the intestinal wall. The sham group (n = 9) received a sham operation. The triple suture stenosis was also performed on wild-type (WT) C57BL/6 mice (group WT, n = 9). 6 weeks post-surgery all animals were sacrificed and samples from the ileum 3 cm proximal and 3 cm distal to the intervention site were collected for histopathological evaluation. The Crohn-like changes were assessed using a modified colitis histological scoring system (based on Katakura et al., JCI 2005; 115: 695–702). Results Proximal to the intervention, the mean colitis score of stenosis group (10.18 ± 0.87) was significantly higher compared with sham (6.33 ± 0.97, p: 0.009) and control group (5.00 ± 0.91, p: 0.001). There was no difference between sham and control group (p: 0.332). No significant differences between the groups were reported distal to the intervention. The triple suture technique led to Crohn-like inflammatory lesions only in the TNFΔare/+ mice, as shown from the significantly increased score compared with WT mice proximal and distal to the stenosis (10.18 ± 0.87 vs. 0.67 ± 0.37, p < 0.001 and 9.20 ± 1.09 vs. 0.33 ± 0.24, p < 0.001). Conclusion The creation of a stenotic segment in the intestine of TNFΔare/+ mice, led to higher colitis score than expected. The probable mechanism is the increased intraluminal pressure proximal to the stenosis. This suggests that mechanical forces contribute as important co-factors in the pathophysiology of CD, in genetically predisposed populations.

Abstract Purpose The most frequent long-term complication after ileocecal resection in Crohn’s disease is anastomotic recurrence and subsequent stenosis. Recurrence typically begins at the site of the anastomosis, raising the question of whether the surgical technique of the anastomosis could affect recurrence rates. Kono-S anastomosis is a hand-sewn antimesenteric functional end-to-end anastomosis that offers a wide lumen that is well accessible for endoscopic dilatation. The purpose of our study is to review the rate of postoperative complications almost 2 years after the introduction of this technique. Materials and methods This is a prospective single-center cohort study of all consecutive patients with Crohn’s disease undergoing ileocecal resection. Patients’ characteristics as well as specific data for the surgical procedure and short-term outcome were evaluated. Results Thirty patients were operated for Crohn’s disease of the terminal ileum (n = 24) or anastomotic recurrence (n = 6). Postoperative complications with a Clavien-Dindo Score ≥ IIIb were observed in three patients. One patient showed a hemorrhage and underwent surgical hemostasis. Two patients developed anastomotic leakage; in both cases, ileostomy was created after resection of the anastomosis. The median hospital stay was 9 days (IQR 7–12). A comparison with a historic group of conventionally operated patients of our hospital revealed no differences in short-term results except for the duration of surgery. Conclusion The Kono-S anastomosis is associated with acceptable short-term results, complications, and recurrence rates comparable with the established anastomotic techniques. Longer operation times are observed, but the few published studies concerning long-term recurrence are promising.

IntroductionCrohn’s disease diagnosis and monitoring remains a great clinical challenge and often requires multiple testing modalities. Assessing Crohn’s disease activity in the entire gastrointestinal (GI) tract using a panenteric capsule endoscopy (CE) system could be used as an alternative to colonoscopy and cross-sectional imaging. This study assessed the accuracy and safety of panenteric CE in Crohn’s disease as compared with ileocolonoscopy (IC) and/or magnetic resonance enterography (MRE).MethodsA prospective, multicentre study was performed in subjects with established Crohn’s disease. Individuals with proven small bowel patency underwent a standardised bowel preparation, followed by CE ingestion and IC either the same or following day. MRE, IC, and CE interpretations were performed by blinded central readers using validated scoring systems. The primary endpoint was the overall sensitivity of CE vs MRE and/or IC in Crohn’s disease subjects.ResultsStudy enrolment included 158 subjects from 21 sites in the USA, Austria, and Israel. Of those, 99 were included in the analysis. Imaging modality scores indicated none to mild inflammation in the proximal small bowel and colon, but discrepant levels of inflammation in the terminal ileum. Overall sensitivity for active enteric inflammation (CE vs MRE and/or IC) was 94% vs 100% (p=0.125) and specificity was 74% vs 22% (p=0.001). Sensitivity of CE was superior to MRE for enteric inflammation in the proximal small bowel (97% vs 71%, p=0.021), and similar to MRE and/or IC in the terminal ileum and colon (p=0.500–0.625). There were seven serious adverse advents of which three were related to the CE device.ConclusionPanenteric CE is a reliable tool for assessing Crohn’s disease mucosal activity and extent compared with more invasive methods. This study demonstrates high performance of the panenteric CE as compared to MRE and/or IC without the need for multiple tests in non-stricturing Crohn’s disease.Trial registration numberClinicalTrials.gov NCT03241368

Objective. We aim to analyze the diagnostic yield, diagnostic accuracy, and delayed diagnosis of patients with terminal ileum lesions, providing follow-up suggestions for suspected patients. Methods. We carried out an analysis of 1099 patients who had terminal ileum lesions in our hospital from 2009 to 2019. The endoscopy reports and histopathology reports of terminal ileal biopsies were recorded. Clinical diagnosis and management were reviewed to determine whether there was a need to correct after a follow-up endoscopy result. Results. A total of 1099 patients were found to have terminal ileum lesions, among which 959 in 1099 patients (87.26%) were diagnosed as benign, 17 in 1099 patients (1.55%) were diagnosed as malignant, and 123 in 1099 patients (11.19%) were diagnosed as suspected. The diagnostic accuracies of terminal ileal polyp, cyst, cancer, eosinophilic enteritis, parasite, lymphofollicular hyperplasia, and amyloidosis were 100%. The diagnosis was delayed in 9.93% of Crohn’s disease (CD) and 12.5% of lymphoma. Among the definite cases, the diagnosis was corrected during the follow-up in 12.5% of the patients, while the clinical treatment was corrected during the follow-up in 17.86% of the patients. Among the suspected cases, the diagnosis and treatment was corrected in 61.11% of the patients during the follow-up. Conclusion. Coincident diagnosis of ileitis and ileum ulcer is low. Delayed diagnosis of Crohn’s disease and lymphoma were observed in a certain proportion of patients with terminal ileum lesions. A follow-up endoscopy was strongly recommended for these suspected patients with terminal ileum lesions.

Abstract Background Faecal calprotectin (FC) is a biomarker elevated in active inflammatory bowel disease (IBD). FC is more sensitive in colonic than small bowel IBD. Ileo-colonoscopy is usually performed to confirm a diagnosis of IBD. Isolated non-specific terminal ileitis is often inconclusive despite biopsy. We aimed to assess the factors that predict terminal ileal Crohn’s disease after ileitis is seen at colonoscopy. Methods A single centre retrospective study of all endoscopic cases of isolated terminal ileitis diagnosed at colonoscopy over a 4 year period (January 2015 – December 2018) was performed. Data was obtained from the Unisoft Endoscopy reporting software. Statistical analyses included chi-square, student t-test and binary logistic regression. Faecal calprotectin, CRP and histology were noted. >150μg/mg was used as a cut off for elevated FC. Results 139 cases were identified and exclusion criteria were applied (known Crohn’s disease, colonic disease). 74 cases were included for analysis. The mean age was 43.9. 44 (59.5%) of the cases were women. 38 (51.4%) had FC performed of which 27 (71.1%) had a FC >150μg/mg. 60 (81.1%) cases had macroscopic terminal ileum ulcers, 9 (15%) of these had histological evidence of ulceration. Subsequent diagnoses of Crohn’s disease were made in 15 (20.3%) patients. Odds ratio of 1.28 (p = 0.016, Cl 0.45-0.047) in the TI ulcers + FC >150μg/mg vs. no TI ulcers + FC <150μg/mg. Conclusion 1 in 5 patients with isolated terminal ileitis were subsequently diagnosed with Crohn’s disease. Almost 90% of these new cases had a faecal calprotectin >150μg/mg. There is poor correlation between endoscopic and histological terminal ileum ulceration. We conclude that terminal ileal ulceration in combination with faecal calprotectin >150μg/mg increases the likelihood of a new diagnosis of Crohn’s disease.
