Introduction

Smoking is an environmental and conductual risk factor for the development of Chron’s Disease (CD) and is associated with a more severe course of CD. In contrast, a protective effect is shown in the development and a mild course of Ulcerative Colitis (UC). Smoking leads to cardiovascular disease, cancer and other chronic diseases, and social isolation, anxiety and depression. It is also a predictor of poorer adherence to treatment in young patients.

Results & Findings

50% were women, 52 years old (SD: 12.6). 58.6% suffered CD, 39.7% more than 10 years from onset of disease, 60.7% with biologics; 54.4% in remission and 29.8% mild activity. 24% were active smokers, 60% ex-smokers and 15.5% has never smoked. 60.3% were regular exercisers, and 66% consume alcoholic beverages regularly.
Of those who smoked, 64% were women, 57% suffered CD, 46% was in remission. 85.7% with anxiety and 52.7% with depression, 61.5% perceived their health status as suboptimal. 64.3% consumed alcoholic beverages, 57.1% no physical exercise.
The mean anxiety score was 9 (SD: 3.6), depression score was 5.76 (SD: 3.7). 67.2% had anxiety levels and 32.8% depression. Perceived health status as optimal was 57.9%.
In the bilateral analysis between smoking and the independent variables, only depression and anxiety was associated.

Summary & Discussion

Smoking is an environmental risk factor for the development and course of CD. The aim of this study iis to determine smoking habits and associated factors in patients with Inflammatory Bowel Disease (IBD) in Hospital Universitario del Henares (Madrid).
A transversal study was carried out. Data were collected in a questionnaire ad-hoc and HADS.
Patients with IBD are active smokers, and their percentage is bigger to regular population in Comunidad de Madrid (21.9%). On the other hand, the percentage of ex-smokers with IBD (60%) is much higher than with no IBD; it may be related to IBD development.
It is well known the relationship between IBD and psicosocial aspects. In this study we show the high prevalence of anxiety and depression, which is higher than in general population.
Nurses can play an important role in the psychological care of patients with IBD, especially in prevention and early detection.

Conclusion

Patients with IBD showed a high tobacco consumption, most of which were women and with no healthy habits.
Smoking in patients with IBD is associated with anxiety and depression.

Introduction

In colorectal epithelial neoplasms, lesions classified as type 2B according to the Japan Narrow Band Imaging (NBI) Expert Team classification (JNET), which are characterized by irregular microsurface or microvascular patterns, are often difficult to diagnose accurately using NBI magnifying endoscopy (ME) alone. Therefore, supplementary pit pattern diagnosis using crystal violet (CV)-stained ME (CV-ME) is recommended. However, CV is potentially carcinogenic, and CV-ME is relatively complex and time-consuming. Acetic acid (AA)-enhanced NBI ME (ANBI-ME) has been proposed as a simpler and safer alternative. Based on our previous study identifying 4.5% AA as the optimal concentration[1], this study prospectively evaluated the diagnostic utility of 4.5% ANBI-ME as a substitute for CV-ME (UMIN registration number: 00045621).

Aims & Methods

From October 2021 to March 2024, colorectal lesions classified as JNET type 2B or 3 during colonoscopy were prospectively enrolled until 300 cases were included. Each lesion underwent ANBI-ME with 4.5% AA, followed by CV-ME. The area of suspected deepest invasion was selected, and one representative image from ANBI-ME and one from CV-ME were independently assessed by two expert endoscopists blinded to histopathology. Intermethod and interobserver agreement were evaluated using Cohen’s weighted kappa. Diagnostic accuracy for each modality was calculated using the individual and consensus diagnoses of the two experts (McNemar’s test). AA whitening duration (AD), representing a reversible mucosal reaction, was measured during ANBI-ME and analyzed by histological depth (low-grade dysplasia [LGD], high-grade dysplasia [HGD], superficial submucosal invasive carcinoma [SMs], and deep submucosal invasive carcinoma [SMd]) using Kaplan–Meier analysis and the log-rank test.

Results

After excluding four unresected lesions, 296 lesions were analyzed. Median lesion size was 18 mm. Locations included the cecum (30), ascending colon (47), transverse colon (69), descending colon (13), sigmoid colon (73), and rectum (64); 122 lesions were elevated and 174 flat. Histological diagnosis included 77 LGD, 145 HGD, 18 SMs, and 56 SMd. Good agreement was observed between modalities (κ = 0.65 and 0.62) and between observers (κ = 0.78 for ANBI-ME, κ = 0.66 for CV-ME). Consensus was reached in 216 ANBI-ME and 192 CV-ME cases. Diagnostic accuracy was significantly higher with ANBI-ME than CV-ME for both observers (81% vs. 76%, p = 0.028; 75% vs. 69%, p = 0.025). Among consensus cases, ANBI-ME also showed higher accuracy (66% vs. 57%, p < 0.01). Median AD (in seconds) was 52 for LGD, 80 for HGD, 132 for SMs, and 107 for SMd, with a significantly shorter duration observed in LGD (p < 0.001).

Conclusion

ANBI-ME demonstrated diagnostic performance equivalent to or superior to CV-ME for colorectal lesions classified as JNET type 2B or 3. In addition, AA whitening duration (AD) may complement the assessment of histological depth of invasion.

Introduction

Endoscopic resection techniques, particularly endoscopic submucosal dissection (ESD), are increasingly adapted for lesions located beyond the gastrointestinal tract, including the hypopharynx. Atypical lesions in the pyriform sinus are uncommon and pose significant diagnostic and therapeutic challenges due to their anatomical complexity and limited endoscopic experience. We present a rare case of a flat mucosal lesion in the left pyriform sinus, initially suggestive of low-grade dysplasia (LGD) managed by ESD for excisional biopsy. Our optical diagnosis and resection strategy were based on a previously published case by Di et al., who demonstrated the feasibility of modified ESD in the hypopharyngeal region. (BMC Cancer 17, 712 (2017).

Aims & Methods

A 28-year-old female presented with upper abdominal pain and was referred for diagnostic esophagogastroduodenoscopy (EGD). She was a non-smoker with no relevant oncological family history. Routine examination of the esophagus, stomach, and duodenum was unremarkable. However, careful inspection of the hypopharynx revealed a flat elevated lesion (Paris 0-IIa), approximately 10×10 mm in size, with a demarcated border, located in the left pyriform sinus. Under narrow-band imaging (NBI) with dual focus, intrapapillary capillary loop (IPCL) pattern type IV was observed, raising suspicion for low-grade neoplasia or high-grade neoplasia. The lesion was photo-documented, and the patient was referred for therapeutic resection.
ESD was performed under general anesthesia. En bloc excision was achieved without adverse events; the resection time was 12 minutes.

Results

Histopathologic analysis revealed stratified non-keratinizing squamous epithelium overlying subepithelial lymphoid tissue, consistent with mucosa-associated lymphoid tissue (MALT). Areas of lymphoid follicular hyperplasia with fused follicles were present. The epithelium was non-dysplastic, with regenerative changes and mild intraepithelial lymphocytosis. Immunohistochemistry revealed non-block-type p16 staining, and Ki-67 expression was limited to the basal layer. No morphological or immunohistochemical evidence of high-grade squamous intraepithelial lesion (HSIL) was found.
The patient experienced mild local discomfort for two weeks post-procedure, controlled with ibuprofen. Follow-up endoscopy at one month confirmed complete healing with no recurrence.

Conclusion

This case highlights the growing applicability of advanced endoscopic techniques beyond the gastrointestinal tract and emphasizes the diagnostic limitations of optical assessment in small hypopharyngeal lesions. Despite features suggestive of squamous dysplasia, accurate diagnosis relied on excisional biopsy. ESD proved to be a safe and effective therapeutic option in this anatomically challenging location.

Introduction

Post-operative recurrence (POR) affects a substantial proportion of Crohn's disease (CD) patients following intestinal resection. While ileocolonoscopy remains the gold standard for detecting recurrence, its invasive nature and patient burden have spurred interest in non-invasive monitoring approaches. This study evaluates the performance of faecal calprotectin (FC) and cross-sectional imaging at different timepoints in predicting endoscopic recurrence in postoperative CD patients.

Aims & Methods

In this multicenter retrospective cohort of 895 CD patients who underwent ileocecal resection, we analyzed the diagnostic accuracy of FC measurements at 3, 6-12, and 18-24 months postoperatively for predicting endoscopic recurrence (Rutgeerts score ≥i2 or SES-CD ≥3). Additionally, we assessed the concordance between intestinal ultrasound (IUS) and magnetic resonance imagings (MRI) and endoscopic findings at both 6-12- and 18-24-months using kappa statistics.

Results

FC demonstrated modest discriminatory ability at 3 months (AUC 0.642, 95% CI: 0.530-0.753) and 6-12 months (AUC 0.653, 95% CI: 0.593-0.713), with improved performance at 18-24 months (AUC 0.676, 95% CI: 0.608-0.744). The optimal cutoff values for FC (47.5 μg/g at 3 and 6-12 months; 80.0 μg/g at 18-24 months) were substantially lower than standard thresholds (150-250 μg/g) used in non-operated patients.
At 6-12 months, radiological and endoscopic assessments showed moderate agreement (κ=0.426, p<0.001) with 63.2% concordance. At 18-24 months, IUS demonstrated superior agreement with endoscopic findings (κ=0.531, p<0.001; sensitivity 83.8%, specificity 72.7%) compared to MRI (κ=0.324, p<0.001). Notably, radiological remission at 18-24 months was identified as a significant protective factor against surgical recurrence (OR 0.356, 95% CI: 0.179-0.705, p=0.003).

Conclusion

Non-invasive monitoring with FC shows promise in postoperative CD surveillance, though diagnostic thresholds differ substantially from those established for non-operated patients. IUS demonstrates superior concordance with endoscopic findings compared to MRI, particularly at later timepoints. The protective role of radiological remission against surgical recurrence highlights the importance of transmural healing. Combining FC with radiological assessment, especially IUS, may provide a comprehensive, patient-friendly approach to monitoring postoperative CD, potentially reducing the need for invasive procedures in selected patients but further studies are needed in this direction.
