Appendectomy and inflammatory bowel disease: is there a link? A review

The appendix has historically been considered a rudimentary organ with an unknown function. Currently, its role in the human body has a special place. It has been proved that it is a "piggy bank" for commensal microorganisms and acts as an immunological organ. The impact of appendectomy on ulcerative colitis and Crohn’s disease has been debated for more than 30 years. Removal of the appendix at an early age has been reported to reduce the risk of ulcerative colitis but lead to a progressive course of Crohn’s disease. These observations led to the postulate that there may be an association between appendectomy and inflammatory bowel disease that can be explained by the immunomodulatory effect of surgery. There is still no definitive evidence of a protective or damaging role of the appendix in inflammatory bowel disease, which is a prospect for future research.

The Natural History of Crohn's Disease Leading to Intestinal Failure: A Longitudinal Cohort Study from 1973 to 2018.

The natural history of Crohn's disease leading to intestinal failure is not well characterised. This study aims to describe the clinical course of Crohn's disease preceding intestinal failure and compare disease course and burden between Crohn's disease patients with and without intestinal failure. Patients with Crohn's disease complicated by intestinal failure from Rigshospitalet, Copenhagen (n=182) and a nationwide Danish Crohn's disease cohort without intestinal failure (n=22,845) were included. Using nationwide registries in Denmark, disease course was determined from hospitalisations, surgeries and outpatient medications, and disease burden was determined from employment and mortality data. The 10-year cumulative incidence of intestinal failure following Crohn's disease diagnosis declined from 2.7% prior to 1980 to 0.2% after 2000. Compared to Crohn's disease patients without intestinal failure, those with intestinal failure experienced significantly longer duration of severe disease (50 vs. 19 years per 100 patient-years, p<0.01), secondary to greater corticosteroid use (71% vs. 60%, p=0.02), inpatient contacts (98% vs. 55%, p<0.01), and abdominal surgeries (99% vs. 48%, p<0.01). However, exposure to biologics was not different between the two groups (20.4% vs. 21%, p=0.95), and duration on biologics was shorter in Crohn's disease patients with intestinal failure (2,068 vs. 4,126 days per 100 patient-years, p=0.02). Standard mortality ratio in Crohn's disease patients with intestinal failure was 3.66 [97.5% CI 2.79,4.72]. Patients with Crohn's disease complicated by intestinal failure experienced a more persistently severe preceding course of Crohn's disease but were not more likely to be treated with biological therapy.

Prospective Evaluation of the Prediction Score for a Mild Course of Crohn's Disease (PreMiCC) in Newly Diagnosed Patients With Crohn's Disease: The PROGNOS Study.

The course of Crohn's disease (CD) is highly variable. The Prospektive Evaluation eines Score zur Vorhersage eines milden Verlaufsbei neu diagnostizierten Morbus Crohn-Patienten in gastroenterologischen Fachpraxen (PROGNOS) study aimed to determine the frequency of a mild disease course and validate a proposed prediction score. The PROGNOS study is a prospective study of CD patients who were newly diagnosed and, except for 1 course of 5-aminosalicylic acid or steroids for ≤10 days, therapy-naïve. Among other predefined inclusion criteria, the initial diagnosis had to be made ≤6 weeks before enrollment. All inception cohort patients were diagnosed and screened consecutively in participating gastroenterology practices in Germany specialized in inflammatory bowel disease. All screened CD patients were scored and, if possible, included in the study for up to 5 years (NCT02193048). A total of 201 CD patients were included in the study (43.3% male; mean age 33 years, mean follow-up 38 months). Altogether, 29.5% of the patients had a mild course at 36 months. Among those with a score ≤2, therapy escalation at 36 months was necessary for only 24.2%, whereas in the group with a score >2, therapy escalation was necessary for 70.2% of patients. In the Kaplan-Meier curve showing time to therapy escalation in the 2 groups, there was a pronounced and statistically significant divergence of the curves starting at 3 months and extending to 48 months (P < .001). In this prospective study, about 30% of incident CD patients had a mild disease course. Our suggested PreMiCC (prediction score for a mild course of Crohn's disease) successfully predicted this.

Prior Appendectomy Is Associated With a Milder Clinical Course in Crohn's Disease: A Nationwide Population-based Cohort Study.

Appendectomy may affect the clinical course of Crohn's disease (CD), but rigorous evidence is sparse and contradicting. The aim of this study was to examine the association between appendectomy and the clinical course of CD. All patients diagnosed with CD in Denmark in the period from 1977 to 2017 were identified from the Danish National Patient Registry. Patients with appendectomy were matched with up to 10 comparators with CD and no appendectomy; and rates of CD-related hospital admissions were compared between CD patients with and without appendectomy using incidence rate ratios (IRRs). We used stratified Cox regression analysis to calculate adjusted hazard ratios (aHRs) of initiating treatment with biologics or undergoing intestinal resections. In all, 21 189 CD patients (1936 with appendectomy and 19 253 without) were identified and followed for a median of 13.6 years. Crohn'sdisease patients who had undergone appendectomy experienced a lower rate of CD-related hospital admissions (appendectomy before CD: IRR = 0.83; 95% confidence interval [CI], 0.81-0.85; appendectomy after CD:IRR = 0.85; 95% CI, 0.81-0.88) compared with CD patients without appendectomy. For patients with appendectomy before CD diagnosis, the rate of initiating biologics was lower compared with CD patients with no appendectomy (aHR1-<5 years = 0.61; 95% CI, 0.46-0.81; aHR5-<10 years 0.47; 95% CI, 0.33-0.66; aHR10-20 years = 0.61; 95% CI, 0.47-0.79), as was the risk of undergoing colorectal resections (aHR1-<5 years = 0.94; 95% CI, 0.77-1.15; aHR5-<10 years 0.63; 95% CI, 0.47-0.85; aHR10-20 years = 0.75; 95% CI, 0.54-1.04). Rates of small bowel resections were comparable for CD patients with or without appendectomy prior to CD. Appendectomy performed after CD did not influence the rate of initiating treatment with biologics or undergoing intestinal resections. The clinical course of CD is milder for those who have previously undergone appendectomy.

Surgical tactics for Crohn’s disease complicated by intestinal bleeding

BACKGROUND: The course of Crohn’s disease often leads to complications requiring surgical treatment. One of the most serious complications of Crohn’s disease is intestinal bleeding. AIM: To determine the most optimal timing and extent of surgical treatment in patients with Crohn’s disease complicated by intestinal bleeding when conservative therapy is ineffective. MATERIALS AND METHODS: The article presents the experience of treating patients with Crohn’s disease complicated by intestinal bleeding at the Center for Gastroenterology and Oncopreventology of the Elizabeth Hospital (Russia) and the Republican Scientific Center of Coloproctology (Uzbekistan). RESULTS: Despite the possibilities of conservative treatment, in 33% of cases the therapy was ineffective and required urgent surgical intervention. The degree of intervention was selected individually based on multivariate analysis. CONCLUSIONS: Intestinal bleeding is a life-threatening complication of Crohn’s disease, causing the need for surgical intervention in almost a third of cases. Crohn’s disease is characterized by various damage to the gastrointestinal tract, which require multiple options for resective surgery on the small and large intestines, as well as an individual approach to the degree of intervention. The use of modern methods of complex conservative therapy for Crohn’s disease can reduce the risk of complications and reduce the amount of surgical intervention.

Assessment of intestinal luminal stenosis and prediction of endoscopy passage in Crohn’s disease patients using MRI

BackgroundCrohn’s disease (CD) is an inflammatory disease of the gastrointestinal tract. The disease behavior changes over time, and endoscopy is crucial in evaluating and monitoring the course of CD. To reduce the economic burden of patients and alleviate the discomfort associated with ineffective examination, it is necessary to fully understand the location, extent, and severity of intestinal stenosis in patients with CD before endoscopy. This study aimed to utilize imaging features of magnetic resonance enterography (MRE) to evaluate intestinal stenosis in patients with CD and to predict whether endoscopy could be passed.MethodsMRE data of patients with CD were collected, while age, gender, disease duration, and laboratory test parameters were also gathered. Two radiologists analyzed the images and assessed whether endoscopy could be passed based on the imaging performance. Imaging features of MRE were analyzed in groups based on endoscopy results.ResultsThe readers evaluated the imaging performance for 86 patients to determine if endoscopy could be passed and performed a consistency test (compared between two readers k = 0.812, p = 0.000). In the univariate analysis, statistical differences were observed in the degree of T1WI enhancement, thickness of the intestine wall at the stenosis, and diameter of the upstream intestine between the two groups of whether endoscopy was passed. In multivariate logistic regression, the diameter of the upstream intestine was identified to be an independent factor in predicting whether endoscopy was passed or not (OR = 3.260, p = 0.046).ConclusionsThe utilization of MRE signs for assessing the passage of an endoscope through the narrow segment revealed that the diameter of the upstream intestine emerged as an independent predictor of endoscopic passage. Before performing an endoscopy, MRE can aid in evaluating the passage of the endoscope.Critical relevance statementThis retrospective study explored the imaging features of MRE to evaluate intestinal stenosis in patients with Crohn’s disease and determined that the diameter of the upstream intestine of the stenotic segment was an independent predictor in assessing endoscopic passage.Key points• Endoscopy is crucial in evaluating and monitoring the course of Crohn’s disease.• The diameter of the upstream intestine of the stenotic segment was an independent predictor in assessing endoscopic passage.• MRE can aid in evaluating the passage of the endoscope in stenotic segments of Crohn’s disease.Graphical

Evaluation of a Multimodal Stress Management and Comprehensive Lifestyle Modification Program on Quality of Life and Gastrointestinal Symptoms in Patients with Crohn’s Disease: A Randomized Controlled Pilot Trial with 9-Month Follow-Up

Introduction: Stress and lifestyle factors impact the course of Crohn’s disease (CD). Our primary objective was to assess whether patients with CD benefit from a mind-body-medicine stress management and lifestyle modification (MBM) program. Methods: This 9-month two-arm pilot trial was conducted in Bamberg, Germany (2020–2021). Patients (18–75 years) with mild to moderate activity of CD and stable medication were enrolled and randomly assigned to either a 10-week MBM program (intervention group, IG) or a single 90-min education session (waiting list control group, CG). Primary endpoints were quality of life (IBDQ) and disease activity (HBI). Secondary endpoints were emotional distress, core self-evaluation, and inflammatory biomarkers 3 and 9 months after baseline assessment. Results: We analyzed data from 37 patients (IG: n = 19, mean ± SD age 49.6 ± 13.1 years, 68% female; CG: 18, 46.8 ± 11.4, 67% female). Immediately after the intervention, 79% (IG) and 44% (CG) experienced a clinically relevant improvement (IBDQ score ≥16 points). This was similar after 9 months (63% vs. 44%). There was no difference in disease activity (3 months: p = 0.082, 95% CI −1.3 to 2.6; 9 months: p = 0.251, 95% CI −1.2 to 2.5). Secondary outcomes indicated improvements in emotional distress, core self-evaluation, erythrocyte sedimentation rate after three and in emotional distress, T-cell profiling in the blood, and fecal lactoferrin and calprotectin group after 9 months in the IG. Conclusion: Our study suggested benefits of a multimodal stress management and lifestyle modification program for patients with CD. Larger trials are needed to determine if the program can supplement or at least partially replace pharmacological treatment approaches.

Analysis quality of life of Crohn’s disease patients based on the sf-36 questionnaire

Introduction: the relevance of the problem of quality of life (QOL) in Crohn’s disease (CD) is due to the increasing prevalence of inflammatory bowel diseases (IBD), the progressive course of this disease, frequent exacerbations, the presence of complications, which leads to early disability and increases the risk of surgical interventions. Purpose: To analyze publications describing the quality of life of patients with Crohn’s disease. Materials and methods: A search was conducted for publications carried out from 2003 to 2023 on databases using keywords: inflammatory bowel diseases (IBD), quality of life (QOL), Crohn’s disease, SF-36 questionnaire. X articles were found. X papers were selected for the review, where the SF-36 questionnaire was the main tool for studying the quality of life of patients. 13 papers were found and selected for the review, where the SF-36 questionnaire was the main tool for studying the quality of life of patients. Result: Most researchers had convincing confirmation that the quality of life of patients with CD is worse during exacerbation on all studied scales in comparison with healthy people, while during remission it does not differ from the quality of life of people without this disease. Factors that improve and worsen QOL in CD have been identified. Conclusion: in people of different ages with the active course of Crohn’s disease, the quality of life is significantly impaired, but the quality of life of children and adolescents requires additional study.

The Impact of Obesity on Inflammatory Bowel Disease.

Obesity is prevalent in the inflammatory bowel disease (IBD) population, particularly in newly developed countries where both IBD and obesity in the general population are on the rise. The role of obesity in the pathogenesis of IBD was entertained but results from available studies are conflicting. It does, however, appear to negatively influence disease course whilst impacting on our medical and surgical therapies. The pro-inflammatory profile of the visceral adipose tissue might play a role in the pathogenesis and course of Crohn's Disease (CD). Interestingly, isolating the mesentery from the surgical anastomosis using a KONO-S technique significantly decreases anastomotic recurrence rate. Anti-obesity therapy is not widely used in IBD but was suggested as an adjunctive therapy in those patients. In this review, we aimed to highlight the epidemiology of obesity in IBD and to describe its influence on disease course and outcomes.

Resection of anorectal fistula cancer associated with Crohn’s disease after preoperative chemoradiotherapy: a case report

BackgroundAnorectal fistula cancer is often diagnosed in an advanced state, and radical resection is difficult when invasion of the pelvic wall is observed. In addition, there is currently no clear evidence for perioperative treatment of locally advanced cases. We report a case of anorectal fistula cancer with widespread infiltration diagnosed during the course of Crohn’s disease, which was curatively resected after preoperative chemoradiotherapy.Case presentationA 49-year-old man who had been diagnosed with Crohn’s disease (ileocolonic type) at the age of 25 and was found to have an anorectal fistula and perianal abscess at the age of 44 was referred to our department with complaints of abdominal pain and diarrhea. Computed tomography (CT) showed anal stenosis due to a pelvic mass. Pathological analysis of a biopsy taken under general anesthesia indicated mucinous carcinoma. Magnetic resonance imaging (MRI) revealed infiltration into the prostate, seminal vesicles, levator ani muscle, and left internal obturator muscle, and the patient was diagnosed with cT4N0M0 cStage IIIB anorectal fistula cancer (UICC TNM classification 8th edition). After performing a laparoscopic sigmoid colostomy, chemoradiation therapy (capecitabine + oxaliplatin, 50.4 Gy/28fr) was initiated. The patient then underwent laparoscopic total pelvic exenteration, colonic conduit diversion, extensive perineal resection, and reconstruction using bilateral gluteus maximus flaps and a right rectus abdominis musculocutaneous flap. The pathological diagnosis was mucinous adenocarcinoma, pT4, and all margins were negative. No recurrence was evident 6 months after the operation without adjuvant chemotherapy.ConclusionWe described a case of curative resection after preoperative chemoradiotherapy for anorectal fistula cancer with extensive invasion that was diagnosed during the course of Crohn’s disease.An accumulation of cases is needed to determine the usefulness of preoperative chemoradiation therapy for local control of anorectal fistula cancer associated with Crohn’s disease.

Paediatric obesity and Crohn's disease: a descriptive review of disease phenotype and clinical course.

In an era of increasing paediatric obesity and inflammatory bowel disease (IBD), this study evaluates the disease phenotype and clinical course of Crohn's disease (CD) in paediatric patients who are obese or overweight. This is a retrospective, single-center, descriptive observational study from January 2010 to May 2020. Participants were included if they were: aged 2 to 18 years at the time of diagnosis, had a confirmed diagnosis of CD, and met WHO criteria for overweight or obesity at the time of diagnosis or within one year before diagnosis. A total of 345 patient charts with CD were screened during the study period, with 16 patients meeting inclusion criteria. Median age of patients was 15.5 years (IQR = 13.6, 16.1). Of the 15 patients over 10 years of age, median anthropometrics at diagnosis included body mass index (BMI) of 27.2 (IQR = 24.9, 29.4) and BMI for age z-score of 1.82 (IQR = 1.58, 2.19). Presenting symptoms included abdominal pain (80.0%), diarrhea (66.7%), hematochezia (66.7%), and weight loss (26.7%). Five patients (33.3%) had obesity-related complications. Median time from symptom onset to diagnosis was 146 days (IQR = 31, 367), and median time from diagnosis to remission was 229 days (IQR = 101.8, 496.3). Patients with elevated BMI and CD present with typical symptoms of IBD, although weight loss was a less common presenting symptom. Time to disease remission is delayed, and obesity-related complications are common. Primary care providers must have a high degree of clinical suspicion in patients to prevent delays to gastroenterology referral and to improve time to disease remission.

Strong impact of sarcopenic state defined by skeletal muscle mass index on postoperative complication of Crohn's disease patients

BackgroundMalnutrition impacts the clinical course of Crohn's disease; however, there is little evidence of its influence on perioperative adverse events. We assessed whether nutritional indicators are associated with postoperative complications in surgical treatment of Crohn's disease. Methods137 patients with Crohn's disease who underwent surgical treatment between January 2011 and December 2020 were included. Skeletal muscle index was calculated by a single CT slice. We analyzed the risk factors for adverse events. Results37 % of patients had postoperative complications. Adverse events occurred more frequently in patients with high serum C-reactive protein, low serum albumin, prognostic nutritional index <38.3, skeletal muscle index <38.9 cm2/m2, abdominoperineal resection, long surgical duration, and mass hemorrhage. Among patients with skeletal muscle index <38.9 cm2/m2, patients who experienced adverse events had higher visceral fat index compared with those who did not (0.85 vs. 0.45, P = 0.04). Multivariate analysis revealed that skeletal muscle index <38.9 cm2/m2 and low serum albumin were the independent risk factors for postoperative complications (Odds ratio, 2.85; 95 % confidence interval, 1.13–7.16; P = 0.03, 2.62; 1.09–6.26; P = 0.03, respectively). Separated by sex, low serum albumin (<3.5 and <2.8 g/dL, male and female, respectively) and skeletal muscle index (<38.9 and <36.6 cm2/m2, male and female, respectively) were statistically related to postoperative complications. ConclusionsSkeletal muscle index is the most useful nutritional predictor of postoperative complications in Crohn's disease patients among other nutritional indices. We believe that these patients are at high risk of postoperative complications and need appropriate nutritional support in the perioperative period.

Feasibility of in vivo magnetic resonance elastography of mesenteric adipose tissue in Crohn's disease.

Although there is growing evidence that functional involvement and structural changes of mesenteric adipose tissue (MAT) influence the course of Crohn's disease (CD), its viscoelastic properties remain elusive. Therefore, we aimed to investigate the viscoelastic properties of MAT in CD using magnetic resonance elastography (MRE), providing reference values for CD diagnosis. In this prospective proof-of-concept study, 31 subjects (CD: n=11; healthy controls: n=20) were consecutively enrolled in a specialized care center for inflammatory bowel diseases (tertiary/quaternary care). Inclusion criteria for the CD patients were a clinically and endoscopically established diagnosis of CD based on the clinical record, absence of other concurrent bowel diseases, scheduled surgery for the following day, and age of at least 18 years. Diagnoses were confirmed by histological analysis of the resected bowel the day after MRE. Subjects were investigated using MRE at 1.5-T with frequencies of 40-70 Hz. To retrieve shear wave speed (SWS), volumes of interest (VOIs) in MAT were drawn adjacent to CD lesions (MATCD) and on the opposite side without adjacent bowel lesions in patients (MATCD_Opp) and controls (MATCTRL). The presented study is not registered in the clinical trial platform. A statistically significant decrease in mean SWS of 7% was found for MATCD_Opp vs. MATCTRL (0.76±0.05 vs. 0.82±0.04 m/s, P=0.012), whereas there was a nonsignificant trend with an 8% increase for MATCD vs. MATCD_Opp (0.82±0.07 vs. 0.76±0.05 m/s, P=0.098) and no difference for MATCD vs. MATCTRL. Preliminary area under the receiver operating characteristic curve (AUC) analysis showed diagnostic accuracy in detecting CD to be excellent for SWS of MATCD_Opp [AUC =0.82; 95% confidence interval (CI): 0.64-0.96] but poor for SWS of MATCD (AUC =0.52; 95% CI: 0.34-0.73). This study demonstrates the feasibility of MRE of MAT and presents preliminary reference values for CD patients and healthy controls. Our results motivate further studies for the biophysical characterization of MAT in inflammatory bowel disease.

Molecular Mechanisms of the Antitumor Effects of Mesalazine and Its Preventive Potential in Colorectal Cancer

Chemoprevention is one of the ways to fight colorectal cancer, which is a huge challenge in oncology. Numerous pieces of evidence indicate that chronic inflammation in the course of Crohn’s disease or ulcerative colitis (UC) is a significant cancer risk factor. Epidemiologic studies suggest that long-term use of non-steroidal anti-inflammatory drugs (NSAIDs), including mesalazine, has beneficial effects on colitis-associated colorectal cancer. Mesalazine is a first-line therapy for UC and is also widely used for maintaining remission in UC. Data showed that mesalazine has antiproliferative properties associated with cyclooxygenase (COX) inhibition but can also act through COX-independent pathways. This review summarizes knowledge about mesalazine’s molecular mechanisms of action and chemopreventive effect by which it could interfere with colorectal cancer cell proliferation and survival.

Creeping Fat in Crohn's Disease-Surgical, Histological, and Radiological Approaches.

During the course of Crohn's disease, the response of mesenteric adipose tissue to the production of inflammatory mediators and bacterial invasion through the intestinal mucosa results in the formation of creeping fat. Creeping fat describes the arresting finger-like projections that surround the inflamed bowel. In this review, the microscopic and macroscopic features of creeping fat and histological evidence for the importance of this tissue are discussed. Moreover, the most recent insights into the radiological assessment of creeping fat in patients with Crohn's disease are reported. Advances in imaging techniques have revolutionized the possibility of visualization and quantification of adipose tissue depots with excellent accuracy. Visceral fat has been significantly correlated with various Crohn's-disease-related outcomes. Despite the difficulties in distinguishing physiologic perienteric fat from creeping fat, the growing interest in fat-wrapping in Crohn's disease has rejuvenated radiologic research. With regard to the noninvasive fat-wrapping assessment, a novel CT enterography-based mesenteric creeping fat index has been developed for the mitigation of the confounding effect of normal retroperitoneal and perienteric adipose tissue. Research on machine learning algorithms and computational radiomics in conjunction with mechanistic studies may be the key for the elucidation of the complex role of creeping fat in Crohn's disease.

Some features of oral mucosal disease symptoms and clinical manifestations in patients with chronic inflammatory bowel disease

Relevance. The work presents the results of a comprehensive dental examination of patients with vermilion and oral mucosa proper (OM) diseases associated with manifestations of Crohn's disease (CD) and ulcerative colitis (UC).Aim. To determine the cause-related features of complaints and clinical manifestations of vermilion and OM diseases.Material and methods. The comprehensive dental examination included the analysis of complaints, history, and assessment of the vermilion and OM condition and the nociceptive pain severity score according to the Visual Analog Scale (VAS).Results and discussion. In CD and UC, the vermillion diseases clinically manifested in 51.43% and 42.85% of subjects (p &lt; 0.01), OM chronic trauma – in 40.0% and 31.43% (p &lt; 0.05), chronic recurrent aphthae – in 48.47% (p &lt; 0.001) and 31.43% (p &lt; 0.01), glossitis – in 62.86% (p &lt; 0.001) and 25.71% (p &lt; 0.01), glossodynia – in 31.43% (p &lt; 0.01) and 17.15% (p &lt; 0.05) of cases. The main complaints of patients with the detected OM pathology included unpleasant sensations, like rawness and soreness, on taking irritating foods in 100% and 65.71% and talking in 31.43% and 25.71% of cases, dry mouth in 51.43% and 25.71% of cases. The burning mouth syndrome was in 31.43% and 17.15% of patients.Conclusion. The vermilion and the oral mucosal diseases often prevail associated with the clinical course of Crohn'sdisease compared to patients with UC. The VAS pain severity score hinges on CD and UC course (p &lt; 0.055). The variety of clinical manifestations of the vermillion and oral mucosal diseases directly depends on CD and UC, a criterion for developing an integrated approach to their diagnosis and implementing recommendations for their prevention and treatment in practical health care.
